Why did my phone Factory Reset itself?

[moxie4408]

I did not log in to open my phone and it did the very same factory reset. It was not due to failed log-in attempts. Thanks.

We're here to help, moxie4408! What type of device do you have? When did it reset? How do you access your phone?

Thank you for these details, moxie4408. We are here for support and happy to help!

1. What is the make/model of your device? 
2. Was your device remotely accessed when the factory reset occurred? 

3. When did it reset (what date/time, roughly)?

I have a Samsung A20. I access it with a swipe, no pin, and this happened on May 9th. Everything was lost except a contact list I had from 10 years ago. Contacts entered within the last 4 or 5 years were not on the list.
