I was stuck at One UI 6 when I bought my phone. I was waiting for any update but nothing happened. It was an AT&T . I changed it to T-Mobile using SamFw tool. And boom I got 6 updates in 1 day. It was stuck for years in One UI 6. I got ONE UI 6.1 and on May 2nd I got One UI 7. It was the among earliest phone who get ONE UI 7.
