A53. SIM card slot 1 doesn't work after update

[Sman42]

I updated my phone recently, and got One UI 6. And after that SIM card slot 1 stops working.

If a sim card is installed in slot 1 then there is no service, even if the phone is showing E (Egde) and signal level in the notification area. And I checked SIM status, it is showing "connecting".

If I install the same sim card to slot 2 then everything works fine!

I went to carrier office and we tried a few different sim cards there, got same result for all sim cards: nothing works in slot 1 and slot 2 works fine.

Again, it happened after the update, so this is definitely a software bug. 

Very very frustrated and disappointed. Samsung Mobile division and QA - this is terrible!

This is the exact issue I'm facing after the recent OneUI 6 update. I'm in Denmark and this is totally so frustrating. Were you able to manage to fix this issue?

Iam experiencing the same issue.

During Jan 2024, samsung A53 sim slot 2 does not work. Then during April slot 1 also lost.

I tried to factory reset couple of times not fix the issue.

I asked support from Belgium samsung support. They could not resolve it.

I need to throw this samsung phone into Garbage.
