Crashes when loading generated chunks

As new chunks generate, the game suddenly lags and kicks me out of the game. I am only able to wander off at least 4-6 chunks away from my base until the lag suddenly comes. I know that the developers are working hard to make sure that the game works well for all devices, but I would love to adventure off into new biomes that are 1000 blocks away and travel in the End and Nether without having the lag and crashing becoming a major issue because it can really get annoying when you are trying to finish something. Thank you, and I hope that you will see this.
