Even mobile screen has dead pixel. There is a tiny black dot on the screen. I tried cleaning that but it is not going. This appeared after I applied a new screen guard. I just want to confirm whether this is a dead pixel or not. The dot remains fixed at the same place. So it can be a dust particle also. I do not want to remove the screen guard also. It will be wasted if I removed which is applied just a few days ago.
