In my experience, the best prerequisites for a very good functioning of /e/OS are when Stock Android 11 is installed in combination with /e/OS R-11 on the SM-T720 (Wi-Fi) and SM-T725 (LTE).
I also first performed a firmware downgrade from Samsung Stock Android 12-S to 11-R during my installation described above. I assume that this extra effort was a worthwhile time investment. And the e-Recovery ‘R’ V1.x manages the OTA updates completely in the background and flawlessly.
