I have a serious lag on galaxy s7 and Z3c in many maps, mostly on imported map Win10 to PE,
MCPE have 10-30 FPS with 5 chunks and all settings are disable, On the previous update(1.0.9) they have 60 FPS on same maps with max settings.

on older android devices(Galaxy s4/Nexus 4 and Galaxy S3 with android 4.4) can have max settings with 45-55 FPS on same maps(1.1.0.55 and 1.0.9).
