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.

💡 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.
