After installing One UI 4 Android 12 Beta, my phone doesn Not indicate a connection to Verizon's Ultra Wideband 5G Network (used to say 5G UW) or AT&T's 5G+ network anymore. Now, the icon just says 5G no matter which network it is connected to. Used to work just fine on Android 11.
Is it possible to make it show connections to high band 5G on Android 12 like it used to?
Please try installing Google carrier services and then reboot your phone, I have 2 S21 devices and one is on Verizon after the Google carrier application was installed 5g Uw connection
