I have the same problem on samsung galaxy s4, please help
I got my Samsung Galaxy S4 2 to 3 weeks ago and it appears that theres a problem to my device. Recently there have been occasional hangs which causes me to be unable to use my device. Pressing the "Home" nor the "power" button or the screen did anything to get rid of the frozen screen. A notification then pop up saying "Touchwiz Home isn't responding" and gave me options to press "wait" or "ok" but still, im unable to press any of the options due to the frozen screen. My screen then turn off and I am unable to on it until a couple of minutes later. My mobile still functions normally, just that this frozen screen problem with Touchwiz have been occuring out of sudden occasionally when Im not even using the phone. (It happens out of nowhere)
Is there anything I could do to resolve this problem? Or is it a system problem which could be covered under warranty?
Much Help is appreciated. Thank you
