At seemingly random times when taking a photo that makes the camera glitch. More often happens when using the camera hardware button rather than the on screen button but can happen with either being pressed, no special settings just literally default camera settings and snap a picture.when this glitch happens, the screen goes blank, the buttons and screen are all unresponsive and a few seconds later the image reappears at phone Home Screen and camera app has quit, and no photo taken/recorded. Thereafter each time the camera app is loaded, whenever taking a photo is attempted the screen goes black and same thing happens. Occasionally when home screen reappears the phone is unresponsive for a few more seconds and then starts working again. I usually restart at that point or do a soft reset using the volume button / power button sequence because the phone often starts glitching even more as time goes on. After reset and restart then it works ok again for a few hours till the next time.
