S23 can't connect when tmobile signal is weak

[freeman93]

I have an S23 and since the last big OneUI update it seems like I have issues with mobile connectivity.
If the signal is weak, I drop calls and actually lose all connection.    The signal is -115 db
I still have my s21 ultra, and I found that it has no problems in the same area and at the same time.

So that tells me that somehow my S23 is not able to connect when my s21 ultra can with the same signal.

If I go somewhere with a very strong signal like -70  db then its no problem.

Can anyone point me to a solution?  was it the software update or was that a coincindence?

I tried resetting my mobile network settings but it didn't help

Hi @freeman93 

My Samsung Galaxy s²³ Ultra appears fine after the update. 

Maybe try the following troubleshooting step. 

• Reset the Network settings via Settings > General Management > Reset > Reset Network Settings.

You mention t mobile, so guessing you're in the US?
