Hi, My HTC Hero keeps crashing and not sure what the heck is going on. It happens when I am in the middle of a phone call. It just locks up and can not do anything about it. I have to take the back off and remove the battery. Then I replace the battery and power on the Android logo comes up but the little robot doesn't. I have to then take the battery out again and redo the power cycle. Does anyone have ANY idea why this happening ? Regards Anthoni Edit 1: Just to add I am still on the old 1.5 build. Not done any fancy updates (am patiently waiting for 3 still). It has happened 3 times thus far, so it's not like a regular thing.
