Project Treble is a big step forward because Google managed to get major chipset producers to one table and they seem to work together, from what I read. Interesting interview with two Android engineers. Unfortunately, while Android 8 is perfectly able to run on the FP2 (demonstrated by LineageOS 15.1), Project Treble’s completely new standardized hardware abstraction layer will most probably never arrive on FP2’s “old” Snapdragon 801 chipset.
Or not and their phones catch fire and explode (Samsung Galaxy Note 7).
This sounds like a math task that we had to do at school. “Calculate the probability of finding at least one faulty phone.”
