I just purchased this app last night for my Galaxy Nexus (GSM version) that I'm using on Tmo's $30 pre-paid plan (at the moment). I'm having a lot of difficulty with it. Seemed to work just fine last night on wifi when I just test called my wife's phone, but today I tried it on 4g/3g and I'm having a LOT of problems.
1. When I tried calling her number this morning using 4g, it would ring (she verified it rang on her end too), but when she picked up neither one of us would hear anything.
2. In between calls GrooveIP would log out of google voice and suddenly be unable to log back in. When I went into the app it prompted me for my password, which I correctly typed in, and it gave me a "incorrect username or password" error. Then several minutes later it suddenly connected successfully.
3. The app actually restarted my phone at one point - was the strangest thing, because it didn't actually hang or shut the phone off, it just went to the boot animation all of a sudden. Really weird.
4. It doesn't seem to work with my Bluetooth at all - calls made do not use my car's system, though all calls made with the stock dialer do.
I tried a variety of settings (synchronize voice, among others) with no luck, but I admit that I don't know much about what they really do, so I might have been blundering about.
Is all of this because I'm running android 4.0? Any help is appreciated.
