Why did my phone Factory Reset itself?

[TomH4]

I pulled my phone out of my pocket and it had factory reset itself and was on the "Lets Get Started" screen. I was able to restore from backup but want to know why it happened. If the phone factory resets due to too many failed login attempts (while in my pocket) does that get logged somewhere, and if so where can I check it?

Phone is a Galaxy S10e Rev1.0 running Android 10.

Thanks,

Oh no. I can only come to the same conclusion that the movement activated the login screen, and there were too many unsuccessful login attempts. There's no log file of these attempts. 

In Settings> Lock Screen > Secure Lock Settings, is Auto factory reset now on or off?
