Everything seemed to work fine until i use my phone to call someone. During the call i had to open up my dial-pad but heres the problem when i lifted the phone up from my ear the dial-pad didn't showed up it was just a black screen i tried pressing home button and power but nothing and b4 i just lift it from my ear and the dial-pad shows up but NOT ANYMORE. Also the only way for me to hang up is to shut down my phone and open it again. Can someone help me PLZ!!!!! I really like this phone PLZZZ
