One UI 6 _ data/connection issues

[As1mi]

I upgraded my S22 ULTRA to one ui 6 and have had issues with data and connection [I'm with EE and 99 percent no issues, b4 update] Since update at times I've NOT been able to CALL anyone or RECEIVE CALLS. At times no Internet connection, which are needed especially for work purposes.

I reset mobile data, i wiped cache through recovery mode and the issue was persistent.

I ended up using Odin to FLASH one ui 5.1. No issues after doing that. I recommend people not to upgrade until they have an update for one ui6. 

Maybe I'm not the majority but thought id share my exp.

Yep! They released another update about 3 days ago and it's sorted my phone out !! X

Hi ve just got the 22 ultra for Christmas and having same problems is there any fix for it ve tried alsorts

Its better but still at times unreliable. I was using a back up phone and during that time the s22u was in aeroplane mode. Then when i swapped sims back to the s22u i put it in 4g and that seemed to have fixed the problem. However it is still unreliable at times so I'm still using the other phone every now and again. I also ended up updating the phone as the downgrade was just a temporary fix

Unfortunately, last update available on my s22ultra Verizon phone was 12/17, which did not correct my issues. Hopefully whatever update you received will be pushed out to the rest of us.

Literally bought it as my old one plus just hit the grave after solid 5 years of amazing performance. Unfortunately  some things are just not child proof.   Wanted to go back to old roots and try Samsung again. Day of setting it up was great. Did update the same night and since this morning I've got no data outside or WiFi. Tried tricks  from YouTube. Nothing works. Thinking  of returning  this heap of overpriced plastic back and going back with  One plus.  How does samsung perform with bringing updates or patches like this?. Got 30 days to return this!

Return it unless your willing to wait for 6.1

Same thing for me on Samsung s22 ultra and T-mobile. Last year samsung messed up my S21+ with a faulty update, never acknowledged the issue and left my phone broken for more than 3 months.

Now this issue, never going to buy another samsung again :@

Also, from my last experience half the samsung folks on the forums and service center wont know s****, they'll keep on calling it as a network provider issue instead of escalating it to the right people.

A factory reset fixed my issue. I was messaging with samsung with the Members app and nothing worked but that. Trust me we tried everything except reverting back to the old update through a third party app.

I noticed also I had same problem. Tried many things.

In my case it was just disabled after update somehow.

I have polish version of Android so I will translate to english settings to which I went.

Go to sim manager -> enable mobile data for sim 1 or sim 2.

For me it was disabled after update somehow.

Edit: Somehow I went to galaxy s22. My problem was for m33. But maybe it will fix yours problem too.
