Automatically restarting randomly

[amyf27]

Has anyone else had this issue with the s 21 ultra the last couple days my phone while probably 50% charged randomly shut off and turned itself back on I did check settings it wasn't set to do that daily not sure why it would do that randomly

Have you installed the OS update? Could have a app not playing nice with it.
