Pixel 6a Vibration/Haptics Not Working

** This guide is anecdotal. My phone now has 100% vibration uptime using this repair. If it worked for you, please update with pictures **

The device's haptics do not register notifications, button presses, etc. This guide realigns the pins for a better contact between the motherboard and haptics component.

🔍 Step-by-Step Diagnosis

If your vibration motor is not working, hard reset the phone by holding down the power button + volume up key for 30 secs.

If the vibration comes back after reboot and dies later, your device may benefit from this guide.

The vibration motor usually dies after quick key presses. Some users say that it dies when connected to a weak cellular connection.

Check for similar kernel logs hinting that the vibration motor is not working

💡 Issue with Vibrator Contacts

The vibrator is not firmly attached to the motherboard like other "lego" style connectors. The motherboard has spring loaded pins that press against the vibrator module. After time, I believe the contacts lose their elasticity and make a poor connection, causing many kernel errors. After too many errors, I think the phone locks out the vibrator to prevent further damage to other components.

⚙️ Hardware Solution

Take off the screen and midframe
Locate where the vibrator connects to the motherboard. Using narrow tweezers, grab each pin and gently bend it upwards.
Take out the vibrator module and slightly bend the two pins downwards.
You should feel some tension when screwing back the midframe as the pins press against each other.

-== Problem description ==
+'''Pixel 6a Vibration/Haptics Not Working'''
-iPhone 15 units experience an issue where the rear camera will not switch from 0.5x (ultra-wide) to 1x (wide) or 2x(telephoto), or switches intermittently. This is often due to two capacitors near the rear camera connector developing cold solder joints (improper solder bonding) or failing. These capacitors are part of the camera power circuit — when the connection is unstable, the system cannot properly drive the other camera modules.

-== Symptoms ==
+The device's haptics do not register notifications, button presses, etc. This guide realigns the pins for a better contact between the motherboard and haptics component.
-* Camera stuck on 0.5x
+🔍 '''Step-by-Step Diagnosis'''
-* Lag or delay when switching between lenses
-* Camera intermittently switches but fails again shortly
-== Diagnostic steps ==
+If your vibration motor is not working, hard reset the phone by holding down the power button + volume up key for 30 secs.
-# Confirm the Symptom
+If the vibration comes back after reboot and dies later, your device may benefit from this guide.
-#* Open the Camera app.
-#* Attempt to switch between 0.5x, 1x, and 2x zoom.
-#* Note if the camera is stuck on one lens (usually 0.5x) or switching is slow/intermittent.
-# Rule Out Software Issues
-#* Force close the Camera app and reopen it.
-#* Test in third-party camera apps (e.g., Instagram, Snapchat).
-#* Update iOS to the latest version.
-#* Perform a hard reset of the phone.
-#* If the issue persists, proceed to hardware diagnostics.
-# Inspect Camera Connector
-#* Disassemble the phone and visually inspect the rear camera connector on the logic board for debris, corrosion, or mechanical damage.
-#* Clean with IPA (isopropyl alcohol) if necessary.
-# Test with a Known Good Camera Module
-#* Connect a known working rear camera assembly to the board.
-#* If switching works normally, the fault is in the customer’s camera module (replace camera).
-#* If switching still fails, the fault is on the logic board — proceed to step 5.
-# Probe the Lens Switching Capacitors
-#* Locate the two capacitors near the rear camera connector (refer to the location photo in the guide).
-#* Inspect for cold solder joints (dull, cracked, or uneven solder).
-== Repair steps ==
+The vibration motor usually dies after quick key presses. Some users say that it dies when connected to a weak cellular connection.
-# Preparation
+Check for similar kernel logs hinting that the vibration motor is not working
-#* Disconnect battery.
