Galaxy S7 logic board versus battery problem
Sometimes my Galaxy S7 freezes with black screen and blue light. I used to reboot it via the volum down and power buttons. However, it sometimes dies with black screen, no lights, and does not respond to any combination of keys!
I thought of changing its logic board versus battery? Any suggestions?
The problem happened the first time when I used a different charger (not Samsung), and the phone freezed immediatly. Since then, the phone did not accept any Android OS update!
I also noticed that it does not freeze when I do not use network data or WIFI connection!
Is this a good question?
