Hi guys, I have some problems and they are as follows I just bought s20 ultra a few days ago to someone and things were fine but then you said you can do a factory reset to make it clean as new But then I notice that there is a problem, which is to turn off 5G, set LTE network as mandatory, and when going to select network mode, there is no other option but to meet me as mandatory. It doesn't let me press the selection, it just appears automatically, which means it's mandatory Then I went to update the search for UICC open Then it was found that it is a hidden suspicion and it is not acceptable to click on it as shown in the image below. Hope experienced reply as soon as possible.
