So recently whenever I get a call and I accept it the screen does not go off its goes off for maybe like 2 seconds and comes back on. Even if I press the power button it turns off for 2 seconds but comes back on. The only way to actually fox that is to press the home button while on the call to out in background and then it turns off. Why is this happening randomly.
This sounds like an issue with your proximity sensor—did you put your Note8 in a new case by any chance? Sometimes magnetic interference can disrupt the sensor functionality.
If not, you can test if your proximity sensor is working by typing *#0*# into your phone's dial pad, and selecting Sensor. Run your hand across the top of the screen. If the device turns green and vibrates, then your sensor is working fine—likely a setting somewhere that needs to be toggled.
