Set the countdown timer in the clock app to say 30 seconds. After this time the alarm should beep.
Now repeat the excercise but after activating the countdown, turnoff the screen and lock.
The alarm never beeps.
None of my alarm/reminder notifications sound if the screen is off.
Also, I do not receive sms messages if the screen is off
This for me is a major fault and needs to be rectified fast.
Does anyone else experience the above or have I just got a dud phone?
I had an similar issue. My UMI had to different Clock apps (both seemingly the stock version), but one was in the UMI ROM and the other one was restored from previous android backups and downloaded automatically. There's basically no way to tell them apart, except one can be disabled and the other can't. The one integrated in the ROM works without any problems.
This is incorrect section.
This clock could be on due to "daydream" activated. This option helping to monitoring device when is docked (charged). Go to settings - display - daydream.
