Hi , I am using this samsung a7 phone since one year but recently I have been getting issues with the touch screen. First it started with the ghost touch for which i searched on google n got a resolution to master reset my phone. To my surprise after doing that the phone screen started working weird. I mean it will not allow me to use the screen for around 30 mins or so if I keep the screen display always on, n if I press the side lock key and wen I open it again, then again will have to wait for 30 mins or so for the screen to work smoothly. This is a weird thing happening an in this lockdown want some assistance urgently. Can u help??
