So I just got my refurbished Pixel 8 and while I was waiting for the case and screen protector to arrive, I was trying out the phone and OS as this is the first time I'm doing this. Once the case arrived, I put it on the phone and everything worked for a few minutes, then the phone started flashing a yellow screen every few seconds with the lock screen appearing and disappearing. But the moment I removed the case, it still flashed for a bit until it started slowly to return back to normal. The case I got is a Spigen case. I have no idea why the case is making the phone like that. It's so strange to me. Anyone got any ideas? If I need to get a new case, what do you recommend? Idk why the case would be causing this unless its pushing on the volume and power button too hard and making it act this way.
