This is my 2nd envtouch (the first one got damaged, i had to send it back.) but i've been having problems with it lately, even though my first one never gave me any problems. now though, my touchscreen is acting up and won't react to what i'm trying to get it to do. it will vibrate when i touch it, but if i press a button that's all it does, with no other reaction. i've tried to recalibrate it but it only seems to help sometimes. also, my motion thing doesn't seem to be working properly as when i make a call to an automated machine, like my bank, i move my phone away from my ear to press buttons and it's supposed to show me the dialpad, but it remains dark. and it has also starting locking itself when i'm actually on a call which it isn't suppsoed to do. now when i'm on the phone and i need to press a button, i have to press the actual return button, unlock the phone, and then hope that the dial pad will show up. what's the deal????
