I did two things to my Pre2 yesterday, added a few patches from Preware and dropped it in the parking lot. Today I noticed that while making a phone call the speaker does not work and the prox sensor does not disable the screen. Turning the speaker phone on works fine still The first thing I thought about was dropping it and I was ready to kick myself for breaking it. That is until I discovered the interactive tests program and to my surprise the phone's speaker and prox sensor still work perfectly fine, just not with the phone application.
I erased all the patches I had installed, did a luna restart, but still no dice. I have done all the different restarts, still nothing.
Anything else I could try before I doctor it? Such as terminal commands.
