Hey Awesometic, really thanks a lot for the ROM!! It works flawlessly for me on my galaxy tab S3 LTE
the battery is good, the performance of the tablet is A LOT better than the stock ROM and also it's awesome to not have all the bloatware installed!
The only thing that "ruins" a bit the experience and makes me want to go back to the stock is sound, the quad speakers work, but the sound is not really the best, it sounds like it's a phone speaker compared to the stock Samsung UI. I tuned it a bit through audioFx presets, but it lacks all the surround sound that you had with Dolby Atmos, the highs are tingly, there's no bass at all and the overall sound is not equalised well.
Would you be able to extract Dolby Atmos or its settings? That would make this ROM the BEST CHOICE, and better in every aspect. Anyway, other than that, this is already a way better experience than the stock. Congrats and thanks again!!
