Unknown numbers on screen and Information Security Solution pop-up

[Android Central Question]

hello,
I have on my screen (left and right) some strange numbers. Also, an Information Security Solution screen pops-up ever couple of seconds. I did factory reset form both Settings and by pressing buttons, still have them. Why do I have this, how to eliminate them? Sorry, it seems I cannot attach screenshots.
Thank you,
Liviu

Welcome to Android Central! Which phone? Are there any Developer Options turned on in the System Settings?

Hello,
Those are the screenshots. I didn't touch the developer options, and anyway I did 2 factory resets.
Thank you for your help,
Liviu

Again, what device?

Looks like something downloaded, look at most recent apps installed , also put in safe mode to see if goes away to know for sure if 3rd party app causing this .

Factory reset should not delete everything?

If you restore from a back up it could put the same thing back like a app.

Try safe mode then we can go from there.

Welcome to the forums. Did you buy this phone new or second hand? When did this screen appear? Was it the first time you used the phone or after any process that you performed?

Thanks. It's odd the text mentions a pre-release device. Has it always been like this or did it happen after an update or installing an app. As Mustang said this will rule out the latter

It looks like the device was originally a pre-release test device. I'm not sure if you can get rid of that. You could try flashing a stock ROM for it.

Thank you all! I will try a new ROM.
