Thanks for reaching out!
You can access your Lock screen contact information by going to Settings > Lock screen > Contact information.
Let me know if this works for you (and don't forget to click "Accept as Solution" on my comment if it does ♥)
I see. This came out after your One UI 5 update?
Thanks for bringing this up. Seems like a software issue, so let's report this properly and get this fixed!
I'll be sending an error report regarding this, but you can help the process along by sending one yourself. You can do this straight from your Samsung Members app through Support > Send feedback > Error reports. Sending your screenshots will be useful for our devs!
You can also send us an email through spr.ly/SamsungPH-Support or engage with us through our Live Chat Support at spr.ly/Support-SMC (available from 9:00 AM to 6:00 PM) to report this issue.
Really sorry about this. In the meantime, both the Galaxy Store and the Google Play Store have tons of apps that let you customize how your lockscreen works. Maybe while the Contact Information feature is missing, you can try them out?
Yeah, I understand how frustrating this is for you. It's a very useful feature too, and I get why you want it back. We'll do our best to get this feature back to you!
I've already sent an error report from my end, hopefully you can send one too!
I'm happy to hear that! Welcome to Samsung Members. Happy to have you here ♥
We don't just troubleshoot here, it's the place for all things Samsung!
Thanks for reaching out to us here in order to find out how to edit the lock screen contact information feature that was missing after the recent update on your beloved Samsung Galaxy A52s 5G.
We hope that your are satisfy for the meantime, with our replies here.
