How it happens:
1. Plug in charging cable
2. Phone starts to charge
3. Towards 93% and above, usually around 95%, the phone starts vibrating for no specific reasons
4. When it vibrates it may show the charging level on the middle of the screen (big round circle overlay showing charging level)
5. If i unplug the charger it stops doing this
6. The vibration is loud enough and repetitive enough to wake you up
What I tried:
- Silent modes => Didn't work
- deactivate all vibrations for notifications => didn't work
- de-activate charging sound and charging vibration => Testing. Looks like this might have worked for me. Some stupid hidden setup.
