I've upgraded my phone thru kies a month back. And, so far I've observed following bugs in GB 2.3.4 INU version. 1. Fetching wrong album art while swiping for next/previous in the stock music player. 2. A random/frequent pulse noise is occurring while listening to music in the same stock music player. 3. Lags while back to contacts after hung up the call. 4. Lags in running call duration timer in course of the call. 5. Still have the "Unable to turn on WiFi" error which is prolonged from Froyo. 6. Failing to turn on/off the Data connectivity using the power key menu. I don't know where to report these and get them fixed. So, any one knows the solutions please update this thread. Esp, the second issue is more annoying to me since I can't bear this b**ls**t noise while listening to music. Thanks in advance!
