After the June 2022 update, my Galaxy Note 20 Ultra 5G shows mobile network disconnected. Although sometimes I can still get 4G access, the signal is very poor. Worse still, the connection only lasts for a few minutes, and then I have to reset the mobile network to get connected again. I'm using T-mobile.
Really disappointing to hear this.It would probably be a motherboard issue if the problem still persists after a factory data reset and Samsung would charge you a significant amount for the motherboard if your device is out of warranty.
Well, T Mobile is not here in India, so not sure how thing is gonna work but just want to ask if you are using physical sim or esim. If physical sim is the case then, i would suggest you to get a duplicate sim. Many times sim got damaged and cause network issues. If that's a esim then, give a try to physical sim. I don't think its a update issue, as far as i know, if any update cause this either it will be out of network untill you eject or insert the sim again or factory reset.
