Hello guys. Last month after using my friend charger, when I opened any apps my display suddenly become automatic back and then open the apps again repeat for a few times and then it stopped. I thought it was just a one times thing but this month it occur again twice. Is it relate to the charger or is it because of the software issues? Or is it a normal thing to occurs? As I have been using this phone from 2021 and there is no problem ever since. Thank you guys.
