Recently I have updated my phone(s24 ultra) os to one ui7. It's Korean variant. If mobile network is turned on then call drop is must, it's dropped within one minute.When there is no VoLTE sign call drop is not occurring. So there should a VolTE turned on/off buttons in settings. On the other hand loading icon is getting stuck in every app. It seems app app is going to crashed. But apps work properly, just loading icon getting stuck.
It's a major update reset factory data with backup then try to it's again. If you like please accept as a solution it's help to others users also, click on 3dots in my reply section and click on accept solution. Thanks.
