I'm more asking for a friend than myself- I have an Android tablet, but have never had an issue like this.

His Samsung Stratosphere's clock will randomly freeze for about five minutes, then continue as normal. During the time it's frozen he does not receive any messages or calls. He has not as of yet attempted to make a call or send an SMS during this, usually because he doesn't notice it until he gets a small avalanche of texts. The phone is updated, but still shows the Android logo in the upper left corner. There have also been incidences of shutdown, but no full reboots.

I've done some research online, but found nothing explicitly like this. His carrier is Verizon, if that matters at all, and the issue has gotten markedly worse in the last week.
