I am on AT&T. My S23 was updated with One UI 7 successfully yesterday. But since then I have completely lost AT&T wireless service. Only wifi call works. I inserted the Sim card to my older AT&T phones, it works. I talked to AT&T, was told that my account is fine and they couldn't figure why my S23 can't access the network after One UI 7 update.
One thing I noticed is that, when I tried to update my system again, this message was displayed: "software update was interrupted . No update is available at this time. Please try again in 24 hours". But the update was completed without any iterreuption....Waited 24 hours, still seeing the same message.
Does anyone experience the same issue? Shall I wait for Samsung to roll out a fix? Or is there anything I can do to have it fixed?
Update 5/23: I did a factory reset. Still didn't work. The same "update was interrupted" shows up every time I tried to update the system. It seems to me that the factory reset will keep the same system (One UI 7) while deleting all other apps and data. What a waste of time. Now my phone is a brick!! What's going on Sansumg?!
Update 8/31/2025: had the USB board changed. And it worked! This is a common issue with Galaxy phones. I have seen similar issue on other forums, including weak signal or bad reception. All related to the USB board issue. Somehow the antenna is linked to the board. It's an easy fix. 30 min job.
If the troubleshooting is not helpful, the phone will need to be evaluated by a certified technician. You can use the following link to find a list of service centers in the U.S. that can do the repair: http://www.samsung.com/us/support/service/location or by contacting customer support at 1-800-726-7864.
