Samsung service centre denied about personal data. They told me mobile will be format and all data will be erase.

are you facing same problem now?

No, there is no such option availlable on lock screen of forgot pasword. google and Samsung completely removed this feature a long time ago. in one ui8 Samsung has made security tighter than even before.

don't suggest anyone to hard reset. I know about hard reset but I don't want to loose my data

You bought a old dated phone. you should buy m17 which come with android 15 aur wait for m37 which come with android 16.
