🛡️ Why This Matters

Sensor problems are often:

• Misdiagnosed
  
  

• Made worse by cheap parts
  
  

• Caused by missing internal components during DIY repairs
  
  

Correct diagnosis saves money — and prevents permanent damage.

⚠️ SECTION 2: High-Pain Sensor Symptoms — What Your Phone Is Actually Doing

If your phone feels “possessed” during calls, notifications, or everyday use, the problem is almost always a sensor stuck in the wrong state.

Below are the most common high-frustration symptoms, categorised by how the sensor is failing — not just which part is broken.

📞 Proximity Sensor Problems (Most Common Sensor Failure)

Your proximity sensor has only two jobs:

1. Detect when something is close to the screen
   
   

2. Detect when nothing is close to the screen
   
   

When it gets stuck in either state, everything breaks.

🖤 STUCK NEAR — “The Black Screen Crisis”

(Phone thinks your face is always against the screen)

What you experience:

• Screen turns black immediately when a call starts
  
  

• Screen will NOT wake during calls
  
  

• Power button does nothing until call ends
  
  

• You can’t hang up or access keypad
  
  

• Call ends only when the other person hangs up
  
  

Why this feels serious:

• You lose control of your phone mid-call
  
  

• Emergency calls become stressful
  
  

• Makes phone feel “dead” or frozen
  
  

What’s actually happening inside:

• Proximity sensor constantly reports “object detected”
  
  

• Infrared reflection is blocked or misread
  
  

• Phone disables screen and touch for safety
  
  

Most common causes (in order):

• Dust or compacted debris in earpiece
  
  

• Missing internal rubber sensor cover (after screen replacement)
  
  

• Adhesive residue blocking sensor window
  
  

• Liquid residue inside earpiece channel
  
  

• Sensor flex damaged during previous repair
  
  

Good news:
✔ Very often fixable without replacing parts

Typical repair outcome:
⏱️ 30–90 minutes
✅ Success rate: 90%+

⚠️ Reality check:
Some iPhone Face ID failures are not repairable — and any shop promising otherwise is misleading you.

Diagnosis determines outcome.

🔁 CRITICAL SYMPTOM — Do Not Ignore

🔴 iPhone Reboots Every 3 Minutes

(Especially iPhone 13–16)

What this means:

• Proximity sensor flex reporting invalid data
  
  

• iOS watchdog triggers forced restart
  
  

• Often caused by liquid or flex damage
  
  

Why this is urgent:

• Continued use can damage motherboard layers
  
  

• Simple sensor issue can escalate into logic board failure
  
  

👉 Immediate professional diagnosis required.

🛡️ SECTION 3: Can I Fix This Myself?

Safe Checks That Help — and DIY Mistakes That Make It Worse

Before you spend any money, there are a few safe things you can try.
Some sensor problems are simple. Others become permanently unrepairable if handled incorrectly.

This section shows you what’s safe, what’s risky, and what to avoid completely.

✅ SAFE DIY CHECKS (Low Risk, Often Effective)

These steps fix or confirm up to 40% of sensor problems, especially proximity and vibration issues.

✅ 1️⃣ Remove Screen Protector & Case (MOST IMPORTANT)

Why this works:

• Proximity and light sensors use infrared light
  
  

• Poorly designed screen protectors block or reflect IR
  
  

• Thick cases can shadow the sensor window
  
  

Do this:

1. Remove screen protector completely
   
   

2. Remove case
   
   

3. Make a test call
   
   

4. Hold phone to ear or mirror
   
   

If the screen now behaves normally:
🎉 Problem solved — no repair needed

📌 This is the #1 free fix we see daily.

✅ 2️⃣ Clean the Sensor Window Properly (Not Aggressively)

Safe cleaning method:

• Power off phone
  
  

• Use microfiber cloth
  
  

• Light isopropyl alcohol (70–99%)
  
  

• Gently clean earpiece area
  
  

Why it helps:

• Skin oils, dust, and makeup block IR sensors
  
  

• Even invisible residue causes failures
  
  

⚠️ Do NOT use:

• Toothpicks
  
  

• Needles
  
  

• Compressed air directly into earpiece
  
  

• Household cleaners
  
  

✅ 3️⃣ Use Built-In Diagnostic Codes (Android Only)

These do not fix hardware, but they confirm what’s broken.

Brand

Diagnostic Code

What It Shows

Samsung

*#0*#

Live proximity & light values

Xiaomi

*#*#6484#*#*

Hardware Test (CIT)

Google Pixel

*#*#7287#*#*

Pixel Diagnostics

Motorola

*#*#2486#*#*

Engineering Mode

Generic Android

*#*#0588#*#*

Proximity test

What to look for:

• Proximity should change from FAR → NEAR
  
  

• Light values should change when you cover sensor
  
  

📌 If values don’t change → hardware or calibration issue.

✅ 4️⃣ Re-Enroll Biometrics (Fingerprint / Face Unlock)

Fingerprint:

• Delete existing fingerprints
  
  

• Clean sensor
  
  

• Re-add same finger 2–3 times from different angles
  
  

Face Unlock:

• Clean front camera & sensor area
  
  

• Re-enrol face in good lighting
  
  

• Remove glasses or masks
  
  

💡 Works well for software-only corruption.

✅ 5️⃣ Check Vibration & Haptic Settings

iPhone:

• Settings → Sounds & Haptics
  
  

• Vibrate on Ring & Silent → ON
  
  

Android:

• Settings → Sound → Vibration & Haptics
  
  

• Enable call, notification, and touch vibration
  
  

📌 If all settings are ON and vibration is still dead → hardware failure.

❌ DANGEROUS DIY (High Risk, Often Permanent Damage)

These mistakes turn fixable problems into permanent ones.

🚫 DO NOT Try to “Calibrate” Proximity Sensors with Magnets

Internet myth:
Waving magnets over the phone fixes sensors.

Reality:

• Proximity sensors use infrared light, not magnetism
  
  

• Magnets can damage:
  
  

  • Compass (magnetometer)
    
    

  • Wireless charging alignment
    
    

• Does absolutely nothing useful
  
  

🚫 DO NOT Open the Phone Without Transferring Sensor Covers

Very common DIY mistake:

• Rubber proximity sensor “bushing” sticks to old screen
  
  

• New screen installed without it
  
  

• Sensor becomes blind
  
  

📌 This is the #1 reason sensors fail after DIY screen replacement.

Once lost, replacements often:

• Don’t fit correctly
  
  

• Cause constant STUCK NEAR or STUCK FAR behavior
  
  

🚫 DO NOT Replace iPhone Touch ID or Face ID Yourself

Why this is irreversible:

• Sensors are cryptographically paired to the logic board
  
  

• Replacing them disables biometrics permanently
  
  

⚠️ Even original Apple parts from another phone will NOT work.

Only authorised Apple systems can preserve pairing.

🚫 DO NOT Hit, Shake, or “Tap” the Phone

“It worked for my friend” stories are myths.

What actually happens:

• Solder joints crack
  
  

• Flex cables tear
  
  

• Motherboard layers separate (modern iPhones)
  
  

📌 Vibration motors don’t “unstick” — they wear out.

🚫 DO NOT Trust “Sensor Repair” Apps

What they can do:

• Display readings
  
  

• Confirm failure
  
  

What they cannot do:

• Repair hardware
  
  

• Restore lost calibration data
  
  

• Fix damaged flex cables
  
  

⚠️ Many are malware or ad-spam apps.

⚠️ CRITICAL WARNING (iPhone 13–16 Users)

🔴 If Your iPhone Reboots Every 3 Minutes — STOP DIY

This is not a software bug.

Cause:

• Proximity flex damage
  
  

• Liquid in earpiece
  
  

• Watchdog timeout
  
  

DIY attempts often cause:

• Logic board sandwich separation
  
  

• Unrepairable sensor + board failure
  
  

👉 Immediate professional diagnosis recommended.

🧠 Why Professional Diagnosis Saves Money

Many sensor problems:

• Don’t need part replacement
  
  

• Only need calibration
  
  

• Are blocked, not broken
  
  

But DIY without tools:

• Misses the real cause
  
  

• Creates new damage
  
  

• Increases repair cost later
  
  

Correct diagnosis first = cheapest outcome.

🔬 SECTION 4: What’s Actually Happening Inside Your Phone

Why Sensors Fail, Why Cheap Repairs Don’t Last, and Why Calibration Matters

Phone sensors don’t “randomly stop working.”
They fail in predictable, technical ways — and understanding this explains why:

• Some fixes are FREE
  
  

• Some repairs fail after a few days
  
  

• Some sensors cannot be replaced at all
  
  

• Calibration is sometimes more important than the part itself
  
  

This section explains what’s really going on, in plain language.

🧠 Sensors Are Not Simple Parts — They Are Systems

Most people think a sensor is just a tiny component.
In reality, every phone sensor is a system made of three layers:

1️⃣ The Sensor Hardware

The physical component (IR sensor, accelerometer, vibration motor, fingerprint reader)

2️⃣ The Connection Path

Flex cables, solder joints, connectors, and shielding

3️⃣ Calibration & Identity Data

Software thresholds, offsets, and in many phones, cryptographic pairing

👉 If any one layer fails, the sensor fails — even if the part looks “fine”.

📞 Proximity Sensor — Why “Stuck Near” and “Stuck Far” Happen

How the Proximity Sensor Really Works

• Emits invisible infrared light
  
  

• Measures reflected light bouncing back
  
  

• Calculates distance based on reflection strength
  
  

Why It Fails

🖤 STUCK NEAR (Black Screen Crisis)

The phone constantly sees reflection.

Caused by:

• Dust or debris in the earpiece channel
  
  

• Adhesive residue after screen replacement
  
  

• Missing rubber sensor bushing (very common)
  
  

• Liquid residue changing IR reflectivity
  
  

📌 The sensor itself is often not broken — it’s being lied to by its environment.

😵 STUCK FAR (Accidental Touch Nightmare)

The phone sees no reflection at all.

Caused by:

• Sensor flex damage
  
  

• IR LED failure
  
  

• Calibration threshold corruption
  
  

• Cheap replacement screens blocking IR wavelengths
  
  

📌 This is where calibration becomes critical.

🔧 Calibration — The Part Most Shops Skip

Calibration tells the phone:

• What “near” means
  
  

• What “far” means
  
  

• What light levels are normal
  
  

• What vibration strength is expected
  
  

Why Calibration Breaks

• Software updates overwrite values
  
  

• Sensors replaced without recalibration
  
  

• Cheap screens lack proper optical properties
  
  

• Data corruption after drops or liquid exposure
  
  

Why Apps Can’t Fix This

• Calibration menus are hidden
  
  

• Require service-level access
  
  

• Need reference values and test environments
  
  

👉 Replacing a sensor without calibration is like replacing a steering wheel without aligning the wheels.

🔆 Ambient Light Sensor & True Tone — Serialization Matters

On iPhone 8 and Later:

• Ambient Light Sensor (ALS) is cryptographically paired
  
  

• Controls:
  
  

  • Auto-brightness
    
    

  • True Tone
    
    

  • Color temperature
    
    

What Goes Wrong in Cheap Repairs

• Screen replaced without transferring sensor data
  
  

• Original Apple screen from another phone used
  
  

• No JCID / calibration programmer used
  
  

Result:

• Auto-brightness missing
  
  

• True Tone gone
  
  

• Screen brightness behaves erratically
  
  

📌 The sensor may still work — but the phone rejects its identity.

📳 Vibration Motors — Mechanical Failure, Not Software

Why Vibration “Suddenly” Dies

• Motors contain moving parts
  
  

• Bearings wear out
  
  

• Weights detach
  
  

• Coils burn over time
  
  

No app or reset can fix:

• Burned windings
  
  

• Broken weights
  
  

• Seized motors
  
  

👉 This is why vibration repair has such a high success rate — it’s a clean, mechanical replacement when done properly.

👆 Fingerprint Sensors — Why Some Can’t Be Replaced

Android Fingerprint Sensors

• Usually replaceable
  
  

• Require:
  
  

  • Correct part type
    
    

  • Recalibration
    
    

  • Clean optical path (under-display)
    
    

iPhone Touch ID

• Cryptographically paired
  
  

• Replacement permanently disables Touch ID
  
  

• Even original Apple parts won’t restore it
  
  

📌 Any shop promising “Touch ID replacement” is either uninformed or dishonest.

🤳 Face ID — Why Some Failures Are Final

iPhone Face ID Is a Security System

It uses:

• Infrared camera
  
  

• Dot projector
  
  

• Flood illuminator
  
  

All components are:

• Factory paired
  
  

• Encrypted
  
  

• Linked to the Secure Enclave
  
  

What This Means

• One damaged component can disable the entire system
  
  

• Replacing parts breaks pairing
  
  

• Apple often replaces the entire phone instead
  
  

👉 Diagnosis determines whether recovery is possible — before money is spent.

🧭 Motion Sensors (Accelerometer & Gyroscope) — Microscopic Machines

These sensors are MEMS devices — tiny mechanical structures that move.

Why Drops Break Them (Even Without Cracks)

• Microscopic arms bend or jam
  
  

• Shock disrupts calibration
  
  

• Moisture causes internal corrosion
  
  

Why Problems Feel “Random”

• Sensor works in some positions
  
  

• Fails in others
  
  

• Rotation delayed or reversed
  
  

📌 This is not software confusion — it’s mechanical physics.

🧱 Motherboard “Sandwich” Failures (Modern iPhones)

From iPhone X onward:

• Logic board is two PCBs sandwiched together
  
  

• Joined by microscopic solder balls
  
  

What Happens After a Hard Drop

• Layers partially separate
  
  

• Sensor lines lose continuity
  
  

• Symptoms appear sensor-related
  
  

⚠️ No sensor replacement can fix this.

👉 This is why proper diagnosis comes before repair, not after.

💸 Why Cheap Repairs Don’t Last

Cheap repairs usually mean:

• No calibration
  
  

• Incorrect sensor bushings
  
  

• Low-quality parts
  
  

• No post-repair testing
  
  

Result:

• Sensor works briefly
  
  

• Fails again days or weeks later
  
  

• Customer pays twice
  
  

We fix the cause, not just the symptom.

🛠️ Our Repair Philosophy (Why Our Fixes Last)

We don’t just replace parts. We:

• Measure live sensor data
  
  

• Restore calibration where possible
  
  

• Use correct optical and mechanical components
  
  

• Test every sensor before return
  
  

If calibration fixes it — we don’t sell you parts.

🛠️ SECTION 5: Our Professional Sensor Repair Process

How We Diagnose, Repair, Calibrate & Test — Step by Step

Sensor repair is not guesswork.
It’s a controlled process designed to identify the real fault, fix only what’s necessary, and return your phone fully tested.

Here’s exactly what happens when you bring your phone to us.

🔍 STEP 1: FREE Sensor Diagnosis (10–15 Minutes)

Before opening your phone, we verify the problem using live data.

What We Test:

• Proximity sensor (NEAR / FAR response)
  
  

• Ambient light sensor (lux response)
  
  

• Accelerometer & gyroscope (orientation vectors)
  
  

• Vibration motor strength
  
  

• Fingerprint recognition accuracy
  
  

• Face unlock response (where applicable)
  
  

• Compass & Hall sensor (if relevant)
  
  

How We Test:

• Manufacturer diagnostic menus
  
  

• Service-level calibration tools
  
  

• Real-world call, rotation, and notification tests
  
  

📌 Why this matters:
Many sensor problems are blockage or calibration-related — replacing parts too early wastes your money.

🧠 STEP 2: Root Cause Analysis (Not Symptom Guessing)

We determine:

• Is the sensor stuck NEAR or stuck FAR?
  
  

• Is the hardware responding at all?
  
  

• Is calibration data missing or corrupted?
  
  

• Was there prior repair damage?
  
  

• Is the fault software, mechanical, or board-level?
  
  

You’ll be told:

• What’s broken
  
  

• What’s NOT broken
  
  

• Whether repair is worthwhile
  
  

No repair begins without your approval.

🧼 STEP 3: Non-Invasive Fixes (When Possible)

If the issue can be fixed without replacing parts, we do that first.

This includes:

• Removing debris or residue from sensor channels
  
  

• Reinstalling missing rubber sensor bushings
  
  

• Correcting misaligned components from previous repairs
  
  

• Software recalibration of sensors
  
  

💡 Many shops skip this step entirely.

If this solves the problem, you pay less — or nothing.

🔧 STEP 4: Precision Component Repair (If Required)

If hardware is confirmed faulty:

We Replace Only What’s Necessary:

• Proximity sensor flex
  
  

• Ambient light sensor module
  
  

• Accelerometer / gyroscope IC
  
  

• Vibration motor
  
  

• Fingerprint sensor (where allowed)
  
  

Our Standards:

• OEM-quality or original-spec parts
  
  

• Correct optical transparency for IR sensors
  
  

• Proper shielding and alignment
  
  

• Clean soldering and connector handling
  
  

⚠️ We do not replace cryptographically paired sensors on iPhones unless functionality can be preserved.

🧬 STEP 5: Calibration & Serialization (The Critical Step)

This is where many repairs succeed — or fail.

What We Calibrate:

• Proximity NEAR/FAR thresholds
  
  

• Ambient light response curves
  
  

• Accelerometer & gyroscope orientation
  
  

• Fingerprint sensor sensitivity (Android)
  
  

• Haptic strength (where applicable)
  
  

Why It Matters:

Without calibration:

• Sensors behave unpredictably
  
  

• Auto-brightness fails
  
  

• Screen stays on or off incorrectly
  
  

• Repair “works today, fails tomorrow”
  
  

📌 Calibration requires professional tools, not apps.

🧪 STEP 6: Multi-Stage Quality Testing (Before You Pay)

Your phone is tested in real-world conditions:

Our Testing Checklist:

✔ Test calls (screen turns off/on correctly)
✔ Rotation in all orientations
✔ Brightness response (dark & bright environments)
✔ Vibration strength (calls, notifications, haptics)
✔ Fingerprint accuracy (multiple scans)
✔ Face unlock reliability (if applicable)
✔ No unexpected reboots or errors

If it doesn’t pass all tests, it doesn’t leave the bench.

🧾 STEP 7: Transparent Handover & Advice

Before you leave, we:

• Show you the repaired function
  
  

• Explain what failed and why
  
  

• Advise on prevention (screen protectors, cases, care)
  
  

• Provide warranty details
  
  

You walk away informed, not confused.

🛡️ Our Repair Ethics (Why Customers Trust Us)

• ✔ No unnecessary parts replaced
  
  

• ✔ No charge if calibration fixes it
  
  

• ✔ No false promises on unrepairable sensors
  
  

• ✔ No “trial and error” billing
  
  

• ✔ No rushed testing
  
  

If we can’t fix it properly, we’ll tell you — before touching your phone.

💰 SECTION 6: Pricing After Diagnosis

Transparent, Tiered & Fair — No Guesswork, No Surprises

Sensor repairs do not have one fixed price, because the cause matters more than the symptom.

A screen that won’t turn off during calls could be:

• A blocked sensor (FREE fix)
  
  

• A calibration issue (low cost)
  
  

• A damaged sensor flex (component repair)
  
  

• A motherboard-level fault (not worth repairing)
  
  

That’s why diagnosis always comes first — and why ours is FREE.

🔍 Why Sensor Repair Prices Vary

1️⃣ Software vs Hardware

• Software calibration → inexpensive
  
  

• Hardware replacement → higher cost
  
  

2️⃣ Sensor Type

Some sensors are:

• Simple (vibration motors)
  
  

• Integrated (proximity + ambient light)
  
  

• Security-paired (Touch ID / Face ID)
  
  

3️⃣ Phone Model

• Flagship phones use more complex sensor systems
  
  

• Newer models require more precise calibration
  
  

4️⃣ Previous Repair Quality

• Missing sensor bushings
  
  

• Cheap screens blocking IR
  
  

• Incorrect parts installed elsewhere
  
  

📌 Fixing someone else’s mistake often costs more than a first-time repair.

🧾 Our Pricing Philosophy

✔ You only pay for what’s actually broken
✔ No “trial and error” part swapping
✔ Calibration billed lower than replacement
✔ If it’s not worth fixing — we tell you

FREE diagnosis. No obligation.

📌 Saying “no” saves customers thousands.

💡 How to Avoid Overpaying for Sensor Repairs

✔ Always get diagnosis first

Never accept pricing without testing.

✔ Be suspicious of “flat prices”

Sensors fail in different ways.

✔ Avoid shops that promise biometric replacement on iPhones

It’s not possible without losing security.

✔ Cheap screen replacements often create sensor problems

Fixing the aftermath costs more.

🛡️ Warranty & Peace of Mind

All sensor repairs include:

⚠️ SECTION 7: Why Sensor Repairs Fail Elsewhere

(And How We Prevent It)

Sensor repairs are one of the most commonly misdiagnosed phone problems.
Many customers visit us after paying for a repair that didn’t last — or made the problem worse.

Here’s why that happens, and what we do differently.

❌ Reason #1: Treating Symptoms Instead of Sensor State

What often happens elsewhere:

• Phone shows a symptom → part is replaced
  
  

• No testing of NEAR / FAR values
  
  

• No confirmation of actual sensor behavior
  
  

Why it fails:

• “Stuck Near” and “Stuck Far” behave very differently
  
  

• Replacing the wrong component does nothing
  
  

• Underlying blockage or calibration issue remains
  
  

How we prevent this:

• We diagnose sensor state, not just the symptom
  
  

• Live data testing before any repair
  
  

• We don’t replace parts unless the sensor is proven faulty
  
  

❌ Reason #2: No Calibration After Repair

What often happens elsewhere:

• Sensor replaced
  
  

• Phone handed back immediately
  
  

• No calibration performed
  
  

Why it fails:

• Phone doesn’t know how to interpret new sensor values
  
  

• Thresholds are incorrect
  
  

• Sensor behaves unpredictably
  
  

How we prevent this:

• Calibration is mandatory, not optional
  
  

• We restore correct NEAR / FAR thresholds
  
  

• Motion and light sensors are recalibrated after any repair
  
  

📌 Many “repairs that fail in a week” are uncalibrated repairs.

❌ Reason #3: Missing or Incorrect Sensor Bushings

This is extremely common after screen replacement.

What goes wrong:

• Rubber sensor cover sticks to old screen
  
  

• New screen installed without it
  
  

• Sensor becomes blind or confused
  
  

Result:

• Screen stays black
  
  

• Screen never turns off
  
  

• Random sensor behavior
  
  

How we prevent this:

• We inspect and transfer all sensor bushings
  
  

• Replace damaged covers with correct spec parts
  
  

• Verify optical alignment before sealing the phone
  
  

❌ Reason #4: Cheap Screens That Block Infrared Light

Not all screens are sensor-compatible.

What happens with cheap displays:

• IR light doesn’t pass correctly
  
  

• Proximity sensor reads false values
  
  

• Auto-brightness becomes erratic
  
  

Why this is dangerous:

• Sensor may appear “broken”
  
  

• Shop replaces sensors unnecessarily
  
  

• Root cause (screen) is ignored
  
  

How we prevent this:

• We use sensor-compatible screens only
  
  

• Verify IR transparency before installation
  
  

• Test proximity response with the display installed
  
  

❌ Reason #5: Ignoring Cryptographic Pairing (iPhones)

Some sensors cannot be replaced freely.

Common misinformation:

• “We’ll replace your Touch ID”
  
  

• “We’ll fix Face ID easily”
  
  

Reality:

• Touch ID & Face ID are cryptographically paired
  
  

• Replacing them disables biometric security permanently
  
  

How we prevent this:

• We explain limitations upfront
  
  

• We refuse unethical replacements
  
  

• We diagnose repairability before charging
  
  

📌 Honesty protects your phone — and your money.

❌ Reason #6: Rushing the Repair (Time Over Quality)

What happens in fast-turn shops:

• No pre-testing
  
  

• No post-testing
  
  

• Phone returned quickly
  
  

Why it fails:

• Sensor problems are subtle
  
  

• Some failures only appear in real usage
  
  

• Issues show up hours or days later
  
  

How we prevent this:

• Multi-stage testing
  
  

• Real call tests
  
  

• Rotation and brightness testing
  
  

• Stress-testing before handover
  
  

❌ Reason #7: Misdiagnosing Board-Level Failures

Some sensor failures are not sensor failures at all.

Example:

• iPhone logic board “sandwich” separation
  
  

• Sensor lines lose continuity
  
  

• Replacing sensors does nothing
  
  

What happens elsewhere:

• Parts swapped repeatedly
  
  

• Customer charged multiple times
  
  

• Phone still fails
  
  

How we prevent this:

• We identify board-level faults early
  
  

• We stop the repair before wasting your money
  
  

• We advise honestly if repair is not viable
  
  

🛡️ Our Prevention Checklist (What We Do Every Time)

✔ Live sensor data testing
✔ Root cause analysis
✔ Correct part selection
✔ Mandatory calibration
✔ Real-world usage testing
✔ Ethical repair limits

This is why our repairs last.

🧠 Why This Section Matters to You

Sensor failures are frustrating — but bad repairs are worse:

• You pay twice

❓ SECTION 8: Frequently Asked Questions (FAQ) — Sensor & Notification Issues

🔍 Why did my phone screen go black during calls and won’t turn back on?

This is usually a proximity sensor stuck in the “NEAR” state.
Common causes include dust in the earpiece, a blocked sensor window, missing rubber sensor bushing, or calibration issues after a screen replacement.

In many cases, the sensor itself is not broken and can be fixed without replacing parts.

📱 Why does my screen stay on during calls and press buttons by itself?

This indicates a “STUCK FAR” proximity sensor.
The sensor is failing to detect your face, often due to:

• Sensor flex damage
  
  

• Calibration corruption
  
  

• Cheap or incompatible replacement screens blocking infrared light
  
  

A proper diagnosis determines whether calibration or replacement is needed.

🔔 My notifications work, but vibration is weak or inconsistent — why?

Vibration motors are mechanical components.
Weak vibration usually means:

• Internal wear
  
  

• Loose weights
  
  

• Partial coil failure
  
  

No app or reset can fix this. A physical motor replacement is required for reliable vibration again.

💧 Can water damage affect sensors even if my phone still works?

Yes. Sensors are extremely sensitive to moisture.

Liquid can:

• Change infrared reflection (proximity sensors)
  
  

• Corrode microscopic sensor contacts
  
  

• Cause delayed or random failures days or weeks later
  
  

That’s why sensor issues often appear after liquid exposure, not immediately.

🧼 I cleaned my phone and the sensor worked again — will it fail later?

If cleaning removed dust or residue, the fix can be permanent.
However, if contamination remains inside the earpiece channel or under the screen, the issue may return.

We clean internally, not just externally, to prevent repeat failures.

🔆 Why is auto-brightness missing or not working?

On many phones (especially iPhone 8 and later), this means:

• Ambient Light Sensor calibration data is missing
  
  

• The sensor is no longer correctly paired
  
  

• A screen replacement was done without serialization
  
  

Calibration or proper data transfer is required — apps cannot restore this.

🍏 Can you replace iPhone Touch ID or Face ID sensors?

Touch ID: ❌ Not replaceable. It is cryptographically paired to the logic board.
Face ID: ⚠️ Sometimes repairable, sometimes not — it depends on which component failed.

Any shop promising guaranteed biometric replacement on iPhones is misleading you.

We diagnose before charging.

🤳 My fingerprint sensor stopped working after a screen replacement — why?

This is very common.

Possible causes:

• Incorrect screen thickness
  
  

• Missing sensor alignment ring
  
  

• Calibration not performed
  
  

• Incompatible display
  
  

Fingerprint sensors are extremely position-sensitive. A proper reinstall and calibration usually fixes it.

🔄 My phone reboots every few minutes — is this sensor-related?

On certain iPhones (especially 13–16 series), repeated reboots every 2–3 minutes can be caused by:

• A damaged proximity sensor flex
  
  

• Liquid in the earpiece area
  
  

• Watchdog timeout errors
  
  

This requires urgent diagnosis to prevent further damage.

🛠️ Can a software update break my sensors?

Yes. Updates can:

• Overwrite calibration data
  
  

• Expose existing hardware faults
  
  

• Disable improperly installed replacement parts
  
  

This is why sensors may “fail overnight” after an update — the fault was already there.

⏱️ How long does a sensor repair take?

Most sensor repairs are same-day:

• Diagnosis & calibration: 30–60 minutes
  
  

• Proximity / light sensor: 1–2 hours
  
  

• Vibration motor: 30–60 minutes
  
  

• Motion sensors: 1–3 hours
  
  

Complex cases may take longer, but you’ll be informed upfront.

💸 Why is diagnosis free?

Because guessing costs customers money.

We only charge after we:

• Identify the real fault
  
  

• Confirm repairability
  
  

• Explain the price and options
  
  

If calibration fixes it, you don’t pay for parts.

🛡️ Is there a warranty on sensor repairs?

Yes. All eligible sensor repairs include warranty on:

• Replaced parts
  
  

• Calibration work
  
  

• Repeat of the same fault
  
  

Details depend on the repair type and phone model, and are explained before payment.

📍 Do I need an appointment?

No appointment is needed for diagnosis.
Walk-ins are welcome, or you can book online for a guaranteed time slot.

📞 What’s the fastest way to get help?

WhatsApp is fastest.
Send:
