Wonder if I am missing calls on AquaFish. Looks like something similar that was holding back the 2.0.x update from being public a few months back.

I experienced it first on last Sunday. Had missed a few calls from home and friends. Came to know about it only when they scolded me. According to them, it was ringing and I didn't pick up the calls. Even SMS were not delivered. A restart fixed it that night and delivered a few SMS too, wonder why though! I thought it was a network error then. But I again experienced it today. When I tried calling my own number, it was ringing, but no notifications. And same with SMS. Working fine after a restart now.

I'm still not fully sure if it's a network issue or OS. Will check closely the coming days with a different network and try to investigate. BTW, my current network is BSNL.
