S21 Ultra Loses Data 4g/5g but not texting or calls after update
Hi, Runing a Galaxy S21 Ultra T-Mobile (SM-G998U) My phone pulled down the latest T-Mobile update yesterday around 10am EST time Installed it. Since then I have lost all data connectivity unless using Wi-Fi, texting and phone calls are fine. I tried the troubleshooting below: Restart Power off/Power On Pulled the sim card (while off and On Changing the network modes to LTE/3g and LTE/3G/2G Manually creating an APNwith IPV4/IPV6 ManuallySelecting Networking operators (also tried AT&T then back to T-Mobile) Did some errands in other towns to confirm it is not a tower problem other phone in the house does have 4g/5g full signal. My phone does have full bars as well just missing the 4G/5G symbol.
No Android 12 Update for S21 Ultra
Purchased S21 ultra from Best Buy as device upgrade for Tmobile line about 5 days ago. Device itself is Tmobile (verified by tmobile and their Samsung support). Problem is that it doesn't seem to be getting any update from Tmobile's servers. Contacted TM and they transferred to their Samsung support. Samsung support blamed tmobile and stated its their responsibility to push the update. Tmobile said to wait for 48-72 hours. Been waiting for a while now and no Android 12 update. I could update the firmware on my own using third party solutions but I shouldn't have to as there's risk involved with that. My return period from Best Buy will end soon. Need to figure out if this device will get the update or not. My S21 was on Android 12 for almost a month until I traded it in. Another family member has S21 Ultra and their device is also running 12. Need this figured out fast as my return period is ending soon.
