I have three issues with this phone. If someone could help me with them i would be really grateful 1. Some times the touch does not respond at all no matter what you do? Suppose I want to answer a call when I try drag the slider it would not respond. Likewise with other applications. 2. when you make a call the screen goes blank and attempts to call the person. At times you accidentally call the wrong person from the call log and you cannot end the call as the screen is blank 3. the phone will shutdown for apparently no reason and you may have to remove the battery and put it back, then power it back on. This has happened to me thrice is the past one and half months are these common issues or should I go to the service center for software re installation?
