Did anyone find a solution for this? I had to hard reset my HD2 couple of days ago. After the reset, I installed all the apps, one after another. The phone worked fine for a day, until this afternoon when it started acting crazy. First symptom was that when you type some numbers of the "Phone" screen to look up a contact, I was not able to delete the using the back button. Other keys like up, down, left, right too didn't work in the SMS compose screen. I restarted the phone thinking that it would resolve the issue, but worse. The volume control showed up just after the boot and the "volume up" tone was constantly going off as though I was pressing the volume-up button constantly. I tried rebooting and remove the battery, SD etc, uninstalled few programs, but to no avail.
