I have a foreign purchased S22 Ultra (SM-S908U1), but have no 5G support anymore in China (both China Mobile and China Unicom) after One UI 6.1 update.
I mean okay this might sound a little weird but under the sim manager have you turning off the sim and then back on to have the phone restart and switch and see if that fixes the problem
Hi there, everyone! Have any of you tried to boot in "Recovery mode" and clear the cache partition? You CAN kind of rollback an update by "flashing" it with Odin, but you void the warranty immediately, and if you aren't highly skilled at speaking Andriod, it can be disastrous My humble opinion is that you absolutely DO NOT GO THIS ROUTE. Try clearing the cache partition first by turning off the phone and then long holding the volume up button and power button at the same time until your device turns on and shows you the recovery menu. Tap on the "Repair Apps" option in recovery mode, and that should clear any cache issues. If that doesn't make you a happier camper, try the "Device Care" option. Quickest method for me to access the app is to pull up the apps from your "Home Screen" and typing "D-E-V" (Device Care is not an app you can see by default in the apps. In "Device Care" home screen tap on "Optimize now," if your battery is a drain like an ex spouse, go ahead while in the app and tap on "Performance Profile"-"Light" to prioritize better battery life. That is it, folks! Good luck, and let me know how it works out, please!! Thanks!šš THE END FINALLY!!
