I don't know what is causing it, cause I regularly clean cache and trash from a phone(I'm using clean master) and I even have 12gb free space on a memory. The problem is that when phone goes to the sleep and when I want to turn it and press home button or power button, the screen is still black, the buttons on the sides of home button flash for a second and then switch off as if the phone is still on sleep mode...I have to try several times before the screen flashes and it goes to the lock screen BUT another round of hell starts here...even though I manage to wake phone it still works veeery slow, I can't even type the password on time before the screen blacks out again. I have to restart the phone to get rid of this, after restart it works normal untill the another slow down happens...I don't know what triggers it...at first it happened when I was charging the battery, the wifi was turned on that time and a lot of notifications came and thought that it was the problem. but another time when I was also charging battery the wifi was turned off and no apps were running background, it still happened. I thought it happened only when I was charging battery but once it happened when phone wasn't charging it was just in my bag and when I needed it I couldn't turn it on. I don't know what triggers it, I really want to fix it... is there any solution?? Please help!!!
