-'''Pixel 6a Vibration/Haptics Not Working'''
-<nowiki>**</nowiki> 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.

+<!--
-The vibration motor usually dies after quick key presses. Some users say that it dies when connected to a weak cellular connection.
+You can manually link to external sources for additional information that might not fit here but are useful such as BIOS image dumps, firmware, etc!

-💡 '''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.
