What happened:
- battery died and replaced it with a new one
- used heat gun on the back to open the phone
Issues:
- after battery replacement, it takes cca 5 seconds to respond to everything
- if I turn on/off the screen...it starts blinking continuously (when screen active)
- I put the old battery back and faced the same issues
- I've never had any issues with it before replacing the battery
Phone: One Plus 6
