I have a Galaxy S22 smart phone.
Since it got updated to the One UI 5.0 a couple of months ago, the sleep mode has stopped working for me.
I have it set up in the Modes and Routines app and the clock app.
The time set is 9 PM in the night every day to 7 am in the next morning every day.
I have set it up to turn on the screen grey scale in between these times, with do not disturb turned on too.
Before the update, it worked fine - every day at 9 pm it would turn on and do not disturb would be active.
Now it does not turn on at all.
When I open the modes and routines app, and save the time again by clicking Done, it turns on.
If I don't open the app and click done on a given day, it does not turn on at all.
I have tried resetting all settings once and clearing cache etc. but it does not work at all.
Is anyone else facing this weird issue as well?
Please share your input.
Solved! Go to Solution.
Instead of using the pre-defined "sleep" mode I have created a mode called "My Night Mode" and deleted the sleep mode. So far it works flawless. Starts at right time, stops at right time. Phone goes to dark mode. DND is turned on. Battery saver turns on and off automatically. I am happy.
Also while deleting the "Sleep" mode I got a warning that all associated alarms in the clock app will also be deleted. So yes, there is definately a connection to the clock app somehow with the predefined sleep mode.
Maybe it tries to guess if you are sleeping according to movement of the phone or something. So it turns on according to that? But that is not what I want. I want my DND mode at a specific time. If I fall asleep earlier, people should be able to wake me. If I fall asleep later shame on me I wasted some sleeptime. A specific DND time is something I can communicate to my colleauges and family. Some random guessed sleep time not so much. (My phone sometimes just sits on the desk. Does not mean I am actually sleeping early. People should be able to reach me then.)
I have Samsung note 20, and I am also trying to find out if there's a fix... As far as I know, I have the latest update... And my phone does not go on bedtime mode automatically unless I go into settings. It worked perfectly before. Now it's pretty much garbage because I have to manually do it.
I am having the same problem. It also happened after the software update.
It started working intermittently but now it does not turn off or on automatically for the times I set to turn on and off.
