[Q] Factory Reset Note 2 yesterday, it factory reset itself today (please advise) topic

Good morning,

Sorry that my first post is asking for help. I've always googled any issues I have with my phone, and this forum is often the one that comes up with the goods, so I thought I'd post here.

Issue:
My phone has been having some problems for a while (lagging, freezing, occasionally restarting, System UIDs inconsistent), so finally I backed up the important stuff, and did a factory reset yesterday. After the reset, the phone seemed fine again for the day. Back to being quick, no error messages, and I restored the data I'd backed up.

This morning, the phone seemed fine, then suddenly it restarted itself, and seemed to be stuck on the boot logo, so I popped the battery out, back in and turned it on. It's done another factory reset on itself, had to log back into Samsung/Google accounts, set up WiFi etc, all data gone again.

Thank you.
