[INFO] Zram in 5.1.1 firmware

as everyone may have noticed the update that Sony provided us for android 5.1.1 is much more fluid and fast
Verifying the new firmware came across Zram enabled by default, which does not we obtained in previous firmwares

So Sony is adding many other features to optimize our dispoositivos, that's pretty technical but were not mentioned in its changelog of the new firmware
