HELP!!! MOBILE PHONE LOCKED, ASKING FOR PASSWORD: "Your password contains at least 4 characters, including at least 1 letter."

[DanijelDomazet]

My (wife's) phone (galaxy A52), exactly 1-year-old on this date, suddenly, out of nowhere, started asking for an unlocking password: "Your password contains at least 4 characters, including at least 1 letter."

The phone was not ever locked, neither with PIN, nor fingerprint, nor with a password.

All we can think of is that some OS update happened, and the phone just locked because of a bug in the update procedure.

We tried to unlock it via Find My Phone, but UNFORTUNATELY, even though the phone was located successfully and the service connected to it, but when we tried to unlock, it just said that the remote unlock option was not ON.

This is just terrible. No words to say. Desparate.

Factory reset is out of the question.

What to do?

How to check if I have Find my mobile option available?

[Meftahurrohman]

type a password of at least 4 characters, one of which is a number or vice versa, one of which is a letter, then type, click the word "done" on the right of the keyboard

Samsung is going thru another update as of this weekend & once again I am locked out of my A13. Tech Sppt told me to TAKE IT TO A SAMSUNG STORE IN MY AREA AS THEY HV THE SOFTWARE 2 UNLOCK THE PHONE.  I set this up with a pin which I keep in an excel spreadsheet along w/other user id's & pass. No go. Find my phone found the phone, tells me I M logged in ... so what! 2 yrs ago i wz locked out for 3 days!! When this A54 no longer performs, I will go to a different manufacturer.

I use many functions on the A13 even tho it is no longer hooked up 2 a carrier. When i m on the fone, i use the voice recording. I have several photos on it; use it like a tablet. This is really tiking me off.  I am scared to death that one morning, just like 2 years ago when samsung had an update & required a 2 step, my phone was off for 3 days. I had a terrible time proving to them it was my phone. my carrier had to get involved. one has to wonder what is wrong with their tech/software programmers.
