Some logs are collected recently, and some are few years ago. I just decided to review these logs and summarize my findings.
My results shows that Pixel does not support AptX; the rests do.
What surprises me a bit is the fact that Moto E Gen 2 Verizon LTE does support AptX, while the AptX official website does not have it as AptX enabled device. (Link here, accessed Nov 29 2016)
