I'm currently using a Note 20 Ultra 5G from T-mobile. I had the phone for about 3 weeks. Everything is fast except data speed. I ran a speed test and was very surprised. 5G speed was slower than 4G, in half. I called Tmobile and their tech stated that is the phone (Samsung 5G) issue and they're waiting for Samsung to roll out an update. IS ANYONE WITH TMOBILE HAVING SAME SPEED ISSUE AS I AM? If so please go to Speedtest.net and run speed test on 5G and on 4G. Please let me know.
