Phones can randomly vibrate for several common reasons, including:
- Notification glitches where apps trigger vibrations without visible alerts.
- Background app activities like syncing email or calendar reminders that cause silent vibrations.
- Phone settings related to vibrations on touch or gestures.
- NFC detecting cards or devices nearby, causing vibrations.
- Psychological effects like phantom vibration syndrome, where the brain perceives vibrations that didn't actually occur.
To fix random vibrations, one can check and adjust notification settings, disable background activity for certain apps, turn off touch or haptic feedback vibrations, update or reinstall apps, clear app caches, disable NFC, and restart the phone. On some phones, turning off repeat notification alerts or emergency alert settings can also stop random vibrations. If none of these resolve the issue, it could be due to hardware or rare software bugs.
