I have a Samsung Galaxy A5 (SM-A500FU) with Android 6.0.1. I see frequently the following issue:
1. Screen is turned off
2. Press the power key or home key
3. The screen appears and clock show the correct time
4. I draw the pattern in order to unlock the screen
5. Screen is unlocked, but the clock doesn't show the correct time. I have to wait several second in order to refresh the clock. As long as the phone doesn't "wake-up" (clock is not updated), I cannot start a call, cannot answer a call, etc.
I see sometimes the similar issue, when somebody calls me. I answer the call, but I have to wait several seconds to be able to start to speak (I don't hear the caller and she/he doesn't hear me, too).
Do you have any idea, where shall I find the root cause of this strange behaviour?
