hii i dont know what happen to the phone but it all of a sudden it just reset itself, i thought it was ok but then when it turned back on the touch screen didnt really work properly so i had to turn off the phone manually then after it was fine but later on the screen didnt load right and it froze. everytime i turn off and on again it was always one or the other, ive tried taking out the sim and the battery but nothing works. the last thing i was doing before it reset saving the settings on the htc home customizer. does anyone have any idea whats wrong or came across the same situation?
please help me out here .. and sorry if its in the wrong thread im still trying to get used to this site ><
