Mobile Data dropping after One UI 6.1 update (Samsung S24 Ultra)

[PierreU]

My mobile data connection keeps dropping every few minutes a week after One UI 6.1 update. I need to toggle airplane mode to reconnect to mobile data. I didn't have this issue before so I'm guessing it's not a hardware issue.

I've tried a few things that I saw here but the issue persists.

Troubleshooting steps done:

• Cleared browser cache
• Cleared phone temporary cache
• Installed sim into second slot
• Tried sim in different phone (no issues)
• Changed network mode from 5g to 4g
• Changed network operator from automatic to manual
• Changed APN protocol from IPv6 to IPv4 and IPv4/6
• Uninstalled VPN/Removed VPN profiles

Have you guys had any luck with other troubleshooting steps?

It looks like it has something to do with 5g. Once I limit my phone to connect to 4g only, I don't have the issue anymore, but we need a fix ASAP.

I have had the same issue since the update also. Only had my s24 for a month and having to keep switching airplane mode to force the phone to find the signal is frustrating. I expect better from both Android and Samsung

I have the same issue with my S23 Ultra since the update on 16th Sept.

I also noticed that my network signal strength is pretty low since one of the recent updates. Could that be related? I'm on s23U
