My Samsung Galaxy S4 automatically restarted?

[Rikku Watro]

On December 18, this year, my Samsung Galaxy S4 automatically restarted. It hasn't been manually restarted for a month already, is that why this happened? The SIM card was fine, and my phone didn't have any problems.

Probably was an error int he RAM temporarily. One automatic reboot isn't really anything to worry about. If they become subsequent, and frequent, then it may be a cause for concern.
