Blazes seem to lag up the game, possibly with their smoke particles! When there are multiple blazes in the Nether, my game slows down to the point where turning around is a real hassle, which has led to many deaths in the Nether Fortress. When I switched my game mode to Peaceful in the Nether Fortress I've been slain in, the lag has ceased, and I was able to move about with ease to get my stuff back. My phone model is an Android ZTE GRAND X MAX +. An idea to fix this would be to have a particle option to toggle particles on or off, like in the PC.
