Sometimes the clock will go weird, and the time won't change unless I touch the phone. This morning I woke up at half 8, I went to look at the time on my phone and it said 04:36, then after a couple of seconds updated to the actual time of half 8. As a result of this, my alarm set to half 6 didn't go off. How do I fix this? Note: I don't have any task killer apps, my phone was not turned off, or on silent.
