I am facing this problem with my s21 ultra where my Mobile stops internet completely and only upload sign is shown in the Lte arrows.then I have to toggle airplane mode off-on and mobile data starts working again. This issue is there when I use both the sim cards if I disable one sim card the mobile data works fine. Many users worldwide have been raising this issue but samsung is sleeping. This problem started in August 2020 and after that one UI 4 came and today I updated to one UI 4.1 but still the issue is there worst flagship worst company.
Hi all, actually this is not samsung issue. I had also faced this same issue where i was unable to use internet and only it was showing uploading speed. I just opened Samsung Notes app, disabled SYNC, after that everything is normal.
NOTE: some ISP provider's uploading speed is very low so whenever phone is uploading something, downloading option and all got less speed at which nothing can't work.
