i have a samsung galaxy ace. One time, i was charging my phone and after a couple of hours i took it off from the plug. The next day it wont open! After a couple of days, i bought another battery but then that's when this problem started. It turns off by itself even if im only using it for 3 minutes! And i also noticed how its lagging. I've looked up this prob online and they said that the phone needs to be reformatted, so i reformat my phone. But still, its turning off by itself and is still lagging! What can i do to make it fast? Please help me =(
