Phone Random Restart

[BZT]

Has anybody else had this issue? My watch was on sleep mode, when the phone shut off the watch disconnected and turned off sleep mode. Sleep mode came back on a couple days prior. This happened Tuesday, March 24, 2026.

I'm on the latest OneUI 8.5 Beta, ZZC7

U.S. Unlocked Galaxy S25 Ultra (Samsung Shop Exclusive version)

U.S. Wifi+Bluetooth Galaxy Watch7 44mm

I haven't installed any malicious software recently, my auto restart for optimization in settings says "Never". The phone was charging at the time.

I have the same issue. Started happening last week.

This is my first occurrence, will see what happens this night. What software version are you running?

[userFuc9NYpaLu]

OneUI 8.0 currently. Just updated 10 min ago.

[BZT]

Interesting. I assumed it was because I was on the beta software, but maybe not.

Google searches brought me to the potential issue being old incompatible apps or a factory motherboard issue. Not sure if that's accurate, but apparently others have had the issue.

[BZT]

Yeah. I haven't installed any apps lately, but I do have many sideloaded apps.

Please post this in the beta forum.

My S25 Ultra will do that during Device Care or App updates or Software updates. I suggest you check your settings for those
