I have Samsung A06, I've noticed a weird blinking red light at the top right corner of my phone (Not on the Display) just above where the Wifi Symbol would appear and I know it is not a pixel problem as it doesn't appear on the display and as the blinking light would only appear when I turn on my phone and it just disappear until I turn on my phone again. Also, it is pretty distinct as one can only notice it in a dark room.
A weird blinking red light can indicate a variety of issues depending on the device it’s coming from, but it’s usually a warning signal that shouldn’t be ignored. In electronics like routers, smoke detectors unitv download, or security systems, a flashing red light often points to a fault, low battery, overheating, or a connection problem.
