anti theft false alert

Hi,
My phone switch into alarm. It was in my pocket so it’s false alarm.
I unlock it but I have no idea why it switch to alarm, no log in account or phone to understand the cause. I would understand the reason because when you are in meeting and your phone start to say “stolen phone,…” you don’t feel very comfortable.

Any idea how to find the cause ?

Thanks

Once again :-(((

After new alarms I found the issue and solve it:

I removed Avast from my phone :wink:

Same thing happened to me today. Will use your solution if it happens again. :o
