Network issues after android 12 update

[Mo_miah]

Hi guys, 

I ve been having issues with my S21 after the the android 12 update. 

Network keeps drooping & mobile data will switch on and off continuously. I updated my mobile on the 4 January 2022. Immediately after the upate the phone crashed and now I can't even make a phone call. 

Has anyone found a fix, I have wiped the cache, restarted the phone, reset the network connections and even got a new sim with new network packages/text.

I am at the end of my tether, no acknowledgement from samsung if it was just mobile data or WiFi you could get by but I can't make or receive calls it cuts out.

Please reach out if you have

Same here, the android update in May destroyed my network on my note 10 plus. Only the wifi is working nicely. What a shame to release such a  version.....

Same here for Galaxy Note 10 +, the phone went out of battery in the night and I may have allow the update once booted. Then no network, just wi-fi, the sim is well detected as the pin is asked and can be seen in the settings. Also Airplane mode is stuck in a faded state.
