Why some of my contacts have been deleted from my George's Galaxy A42 5G?

[George1988]

I just received a phone call from a friend who I am speaking any other day.

However his name did not show up. I haven't deleted his phone number from the contact app. 

When I went to the bin it showed that some other people phone number and names has been deleted. 

Any ideas?

Sounds like a glitch to me @George1988 

If this starts to become a regular occurrence then first check if a setting like your Sync is causing this and a Samsung Experience Store  / Samsung Service Centre can take a look too.

@George1988 Hello, do you have another phone with the same Samsung account? In case yes, it is possible that you have deleted contacts on the other phone?
All the best

No, not really.. Thank you for your answer

[George1988]

Will keep that in mind. Thank you for your answer

I am seeing this happen as well, I have no other phone or Samsung account but name and numbers are being deleted

[George1988]

Strange, isn't it?

[mikey12]

Yes my s21 ultra is deleting names and numbers

Don't forget to do back up at least one day of the week
