I've had my S2 since Dec and have never had a dropped call. I ran .320 until .428 came out, then ran .428 until .451 came out, and not dropped a single call on any of those OS's. Yesterday, I installed AppWorld (for the first time ever) to get an app I read about. Since installing it (AppWorld only, as the app I wanted to download said it wasn't available for my device), I've dropped 5 calls. I just deleted it, but was wondering if anyone thinks there could be a correlation between AppWorld and dropped calls?
I would agree on the probable-no, but like I said, I've never had a dropped call until the day I first installed AppWorld, and have not had a dropped call since I removed it.
