I am using the Galaxy W I8150. The problem is whenever the phone is on lock screen, it keeps brighting up every now. I mean the light keep flashes. This happens like organized manner after every few minutes. If the phone is not on the locked state, then also it randomly bright up even I don’t touch anything on it. I checked the background processes and killed few tasks using task killer. Also removed some apps which I suspect as a cause, also changed some apps settings but it is still happening. How can I avoid this? It eats much batter and drains the battery very quickly.
