Screen lags after unplugging the charger.
Hello, I have gotten my TMobile Galaxy S2 for about two weeks now. From time to time I experience a strange unresponsive lag when I unplug the charger after the phone is fully charged. This also happens when I unplug the charger when it's not fully charged.
When I unplug the charger the screen would NORMALLY turn on immediately. But from time to time, after I unplug the charger, the screen would stay off for a good THREE TO FIVE SECONDS before the screen finally turns on! I am wondering if this is normal or did I receive a defective phone? Is anyone else experiencing this?
I am completely fine with this problem if it's normal but if this is abnormal I would like to claim my warranty for a new one as soon as possible.
I am not familiar with these modern phones and I paid a lot of money to purchase this phone so I just want to make sure everything is in the norm.
Thanks in advance for your help!
