Android update causing esim network loss

[Shah120]

This most recent update (see image) for S23 plus is now causing my esim network to frequently disconnect. The only solution is then to turn on airplane mode and then turn off and network comes on again but then goes offline after a while. 

I have tried turning of the esim and on, restarting phone and still happening. I haven't yet tried network or factory reset as want to avoid that for now. 

I don't know what's causing this but do know it happened only since applying this recent android update.

Hi there 👋and welcome

You could try to wipe phones cache partition before factory reset.

Try to turn phone into safe mode see if that would help.

Also you should try networks reset.

Hi, how do I wipe phones cache?

[lminvti]

Turn off your phone
Plug phone to PC, tv etc with usb
Press and hold power button and volume up button until samsung logo appears Then quickly release power button and keep holding volume up button until reboot menu appears then navigate with volume down button till wipe cache partition press power button Restart your phone

Good morning, i know this might sound silly, but have thought it could be down to you using a VPN that's causing the issue?

I use opendns vpn for home Internet filtering, but before this update, there were no problems.

So, I have done the following

- cleared cache through reboot
- replaced esim to physical sim
- reset network connections

However, the mobile network, which is lyca, still keeps disconnecting, and then i have toggle airplane mode on and off again. It's just very random.

I suspect this recent android update has broken something, but I don't know how to fix it.

I will try to remove the vpn and check progress.

From my research, I've found multiple samsung mobile owners having network connectivity problems, which in some cases resulted in the phones motherboard being replaced to fix the issue. I hope that's not the case with me as this was mostly with the S22 model, not S23.

I think Samsung should bring out a rollback feature on updates for the future to avoid issues arising.

Factory reset is the last and worst option especially after you have spent a lot of time setting up your phone and apps, fingerprints, etc. It should only be done when upgrading your phone, in my opinion, or when it's really necessary.

Hello there,

Same problem here. S23, Lycamobile. I tried opposite thing too you - I added e-sim and it didn't help at all. My SIM is working on old phone without any problems.  Started happening after update as well ( I had update on Saturday). 

Hopefully Samsung will sort out that. Do you know what is the best way to report problem to them?

[Shah120]

Hi, I have tried various platforms but only way to report it is here on the Samsung member forums. Hopefully Samsung development team will see this at some point.

A solution for now is to go to Connections, Mobile Networks, and change Network mode from 5G to 4G.

This should stop the phone from constantly going into Emergency Calls Only mode.

It seems something has gone wrong with 5G connectivity after this update putting phone into Emergency calls only mode.
