Minecraft pocket edition 1.12.0.13 how to lower render distance in options.txt

My phone works pretty well, but it’s stuck at a render distance of 5 chunks. How do I lower that in options.txt to 4 (or lower)?

Here’s the options.txt file. It’s gfx_viewdistance, the view distance is 80, and in-game render distance is 5 chunks which causes me tons of lag in multiplayer and in worlds. Nvm I don’t think there’s a way to reduce it since I tried 4 x 16 which gave me the number 64. It just keeps setting it back to 5.
