Frame Freeze

Hello Mojang, the last time I reported about the lag on my phone, I just found out that the cause of the lag was the frame freeze and I think the chunk rendering is the problem, I already know that there was a setting to change the rendering distance but even though I already changed it to the lowest rendering distance possible, I was still experiencing the lag that I just found out that it was a frame freeze. It only happens to me when I play on survival mode in infinite type of world but I don't experience it in flat world and on some worlds like skyblocks. I hope it this will help you fix the lag that I reported here last time.
