My S22 Ultra sits on a low power wireless charger all night. I use it as my alarm clock, and the alarm commences at 7 am. Previously on Android 12 and now on Android 13, intermittently, the screen will not turn on for me to cancel the alarm. I have to hold down the power button to get the restart/power menu. I push to restart, then it needs confirmation to restart, which I push. Then the screen goes black, while the wake-up alarm is continuing to sound. This is repeatable every time the screen does not come on in the morning.
In Android 12 I would get the fingerprint symbol, after restart confirmation, so that I could provide my fingerprint and the phone would restart. In Android 13, this step is missing and I'm stuck.
Only by holding the power and volume down buttons for a long time, about 30 seconds, does the phone eventually restart.
The phone has no physical damage, and works perfectly at any other time. The phone is protected by the Samsung Smart LED cover EF-NS908 while in the wireless charger, and at any other time.
I have one SIM card and one ESIM number in use on the phone.
Samsung wants me to send the phone to them to investigate a hardware fault. Firstly, I can't be without my phone for an unknown number of days. Secondly, I seriously doubt this is a hardware fault.
I've seen other odd symptoms as well. I'll pull down notifications and they won't appear, the top bar will just go transparent. I'll tap a text field and my keyboard won't appear, until I pull down notifications, then the keyboard appears, then the notifications appear?
I did find that, plugging in my phone would sometimes help me cajole it into powering off or restarting. But yeah, seems like something fundamentally wrong with how it's deciding what to show at any given moment.
This is my first Samsung phone, I'd already decided it'll be my last due to bloatware and overly aggressive power saving. This is just icing on the cake. I learned my lesson and will get a Pixel next time.
Having traveled for 10 days, and only used wired charging, there is no problem. Returning home to my wireless charger and the problem is back. 2 out of 3 mornings I have to do a hard reset to stop the alarm in the morning.
