[LeEco Le Max 2 Questions & Answers] ccheney:
I couldn't track down the previous message, but I have been working on making a list of what's added in 26s vs aosp (still in progress). It appears quite a few vendor (non-LeEco) related things are currently missing from the builds but I'm not sure what all they do yet. From what I recall the 32bit libraries for ims are also missing, but I haven't gotten that far in my double checking yet.
