Question Mobile Data extremely slow on Samsung Galaxy S22 Ultra (Snapdragon)

[TheMystic]

I have a Samsung Galaxy S22 Ultra with Snapdragon processor.

I use dual SIMs from different network providers, and both support 5G.

When I'm on mobile data, I find that the internet connection becomes extremely slow, and sometimes doesn't work at all. Switching to the other data SIM under SIM Manager Settings sometimes helps, but often the speed is pathetic. Even though the status bar shows 5G or LTE+ or LTE, the speeds I get most of the time on either SIM is like 2G.

I'm not sure if this has anything to do with the problem, but please note:

1. I use Netguard to block most system apps from connecting to the internet.
2. I use private DNS (dns.adguard.com) and I often get this notification Network has no internet access (Private DNS server cannot be accessed) which goes away after a few seconds.

Is there anything that can be done to resolve this?


Thanks.

Not yet.

adguard is what is causing that, I couldn't find a workaround so have to stop using it, for what I saw, looks like any dns causes the same issue

I have tried turning OFF the dns, but that didn't help.

I have bad news for you, I bought one yesterday and it made calls without problems, but the internet is terrible, and it turned out that the cell phone is on a blacklist in Canada by a cell phone company there and hence the problem.

I'm not in Canada and the S22U isn't on the blacklist of any telecom company here.

At best, this is a software issue.
At worst, this is an issue with the network modem/ radio on the device.

And I hope it is a software issue.

disable 5G and use NEXTDNS ultrafast servers


my LTE is 30-160 MBPS
my 5G is 60-280 MBPS

5G is draining battery like a crazy--so its off for me

I hope all basic troubleshooting is done on this matter. Even if this is not the issue with the operator then for sure it is a Software issue, because, in my S22 Ultra, everything is running perfectly;y fine.

Have bookmarked it. I use dns.adguard.com. I'll give it a shot sometime.

It is most likely a software issue only.

Turning OFF private DNS helps, but only rarely. When i have the problem, nothing i do solves it, including reboot. And when it works, it's pretty much on its own.

Interesting. I see that I can uninstall it (as opposed to disabling). For now, I have deleted it's app data, restricted battery usage and blocked it from accessing internet using Netguard. I'll see how it goes from here. Thanks for this tip.

I was using dns.adguard.com. I disable it and it works. At least much better than witn dns private dns.
Dns.adguard.com work super fine on my Oneplus phones since 2015.. till s22u.
Also i uninstall Google's Carrier Services, like our friend say. Don't see much difference for my phone..
