I surrended to evidence, and rolled my Nexus 7 2012 back to KitKat... What was a frozen, paralized, practically dead brick is now alive and kicking, and almost snappy in its 4.4 personality! OK, it is known that Lollipop on the original N7 is the Windows Vista of Androids, but now I'm curious... can anybody point to a technical analysis of THE F**KING MESS THAT LOLLIPOP IS DOING WITH OLDER DEVICES???
Because... ok, I can understand that N7's HW is old and a bit inadequate, but Chrome on KK starts almost instantly, while Chrome on Lollipop (even after several factory resets, even after testing Cyanogenmod's implementation) sometimes took 5, i mean FIVE, minutes to become responsive!!!
What the hell is Lollipop doing with storage? what did they do to kill performance in such a monstrous and devastating way? I'd like to read something technical about it, because I just can't imagine anything other that filling the code with idle loops, unnecessary reads and writes, and pervert ups and downs from the caches.
(which must have become a trendy thing, since I've read that the N7 with Marshmallow takes HOURS to finish the first boot. Not even Microsoft was able to cause such performance loss when stepping from one Windows version to the next... :-/ )
