My hill is the microsd card slot. I might have to figure out how to make my note 20 ultra last another 40 years, though. :-(
On another note; if compatible, APTX Bluetooth codec is pretty lag free when watching streaming videos. For local videos, there is a bit of noticeable lag on a lot of players, but I use VLC and it has an audio/video sync setting you can manually adjust so it matches up correctly and it will forever save that setup for you.
