I have had my phone for about 6 months. I hae already had it replaced four times. Now everytime i go to send a text or turn on my phone things start popping up like i touched them. Such as when im gonig to ssend a text random letters look like they are being pushed. the only way to stop it is to lock the phone and unlock it. recently that hasnt been working either. I called tech support and suggested i do a hard reset. So i did. there is no downloaded apps on my phone they even suggested i removed all memory cards. So there is apsolutly no influence on my phone. anyone have an idea why this is happening?
