I have a Note 20 US version still on OneUI 4.0 Because I don’t live in the US I don’t get the update offers to 5.1. I can download the files from SamMobile or SamFW and install them. However, I have also an issue with 5G connection to one of the major telcos here. Because I can choose different files from several US telco’s, Q1 should I research first which 5G bands they use, and then choose the one that has the most overlap with local telco’s? Q2 with doing so, would I introduce new problems on my phone regarding different settings or whatever? Any help greatly appreciated!
