I had a previous thread saying that my compass wasn't functioning (http://androidforums.com/support/6561-compass-not-responding-all.html#post39695), but now I'm realizing that there are many things not functioning: 1) Compass is not functioning. Apps that use compass (streetview, skymap, compass, new horizons) hang at a "loading..." type screen 2) Accelerometer not functioning - games/auto-rotation are not receiving input from the accelerometer 3) Caller-lookup is not functioning. Every call received shows up as "Unknown", no matter who the caller is. I'm running JF-1.5, and things have been working for a long time, but only suddenly stopped. At first, this seemed like a hardware issue, but now i'm wondering: are there any software type issues that could cause these issues? Thank you all very much for any input!
