Lag issues, especially around mobs.

I am finding issues with my fps on my Motorola phone, in these screenshots I am clearly doing well with over 40+ fps while in peaceful mode (only 5 render distance, at 8 render distance my game starts to get massive lag spikes simply because of passive mobs spawning and the game becomes unplayable). As soon as I enable medium difficulty, the game instantly drops fps as mobs spawn, and by the time I have 5 zombies in a small area, my fps drop down into the low 20's and high teens (also I am only using 5 render distance, because at 8+ I drop into single digit fps). This also applies for cows and other animals spawning on the surface. And the lag is so intense, that most of the time my game ends up not responding to my taps and I can't attack anything. As of right now it's almost unplayable without peaceful mode, hopefully this gets fixed soon 🙂
