Since the update on April 18, 2021, I've had some weird things going on with my Galaxy S20 Note Ultra and wanted to see if anyone else noticed other odd things.

Since the update,
-Only LTE shows for signal
- I cannot receive/send MMS
-Constant "Network error" messages despite everything working fine.

My best friend's phone on the other hand, had multiple features greyed out and showed no signal at all for about an hour before everything became "normal" again.

I've done almost everything to fix this and have not had luck, but I mainly just want to know if anyone else has had odd things happen out of curiosity.

I had the can't send/receive MMS issue. You will find a few threads here on the same issue. I tried many things, contacted AT&T with no resolution. Then I learned that my APN configuration was missing a lot of critical information. If you have AT&T you may want to try the following which solved the issue for me. If you have another carrier, you will need to find the correct APN values for that carrier. 

AT&T users, try this:

  1. Open Settings
  2. Click on Connections
  3. Click on Mobile networks
  4. Click on Access Point Names
  5. Click Add
  6. Enter the values in this table: Screenshot_20210415180905_Chro-7c7278f1-b46d-428e-bdb5-1b5fc573ba68-1761911783.jpeg

Did all that, still doesn't work. Would taking it to AT&T be better? Tried reaching out to Samsung and a little disappointed, they sorta claimed they didn't know of this issue.

Thank you! Configuring the APN settings as you detailed fixed the issue for me. It's been a frustrating couple of days of trying many other troubleshooting items. I appreciate you sharing this info. Thanks again!
