Unstable data connectivity s24ultra

[pi1010]

Hello All, 

I'm facing persistent issue with Wifi as well as Mobile data. s24 ultra randomly drops the connectivity (Settings show it as enabled ) and I had to turn off and on mobile data to make it work again. This is very irritating while playing games or watching videos. Anyone facing similar issue?  Galaxy S24 Ultra

This seems to solve the annoying issue with losing network for my Base S24 as well. 

Many thanks for sharing this tip!

Same issue here. The network suddenly stops after 15-20 minutes. I am using 2 physical and 1 esim of 3 different service providers. Phone shows Full 5G bars. Its really frustrating as i need to swich mobile data sim every 15 mins and will get good connectivity on that sim for 15 mins. Hope samsung fix this

I purchased the S24 Ultra two days ago, and unfortunately, I’m encountering a few issues:
-During calls, it falls back to voice-only mode despite having VoLTE enabled on the SIM. I am working on resolving this.
-Network coverage seems inconsistent, leading to degraded call quality and occasional issues with the data connection.

I plan to upgrade the software tonight and hope this will improve the situation.

I am facing the same issue.

For me wifi works just fine but whenever I switch to mobile data, after few minutes the network suddenly disappears for like 10-15 seconds and then I have to enable then disable flight mode to enable it and that too does not work always.

How a big company can make such an error in their flagship is beyond my understanding.  

The standard features that are used daily and are core for the smartphone should always be the priority.

Same issue here on my brand new S24 base exynos upgraded from S23 base snapdragon. I've tried resetting APN, reboot, insert sims again and it's regardless whether I have sim1 or sim2 active. Signal status says still connected and I can see signal quality go up and down as I move (meaning there is an active good connection, yet cant ping 1.1.1.1)

It seems to only happen under active use. I've yet to wake up to no internet. Though it could be that when there is cell change it works again.

Connecting to a wifi router and then disconnecting is enough to solve it.

So I'm half a day into the new 2 GB OneUI update, so far mobile data is fine!

I think your VPN is causing it, when I turn it off it doesn't do it

Update: I am not facing this issue anymore on my S24U after One UI 6.1.1 update.

I am quiet frustrated with this network issue over s24+ it keeps dropping and each time have to refresh the network and stays 20 mins no use ..I tried changing my new sim but no use ..quiet frustrating.. no one is properly supporting this issue

The "select automatically" is not highlighted so it won't let me disable it.

I traded in my S22 Ultra because of the same problem. I spoke to a tech at Samsung and he confirmed they were having the issue of the phone falling of the network..so he advised me to upgrade so I did to the S24 Ultra and now I have the same exact problem..can't make or receive calls for a few minutes at a time..I get a message that says my phone is not registered on a network. Very frustrating..
