All armor is normal but if you put enchantments on it everyone of it would have a trashy texture.

This bug has going on for years and it's hard to play when you got this trashy texture because of this bug. I uninstalled it many times even last year I already did it, I logged out my Microsoft account and logged in it again but nothing changes and I don't know if it was on my phone or it was already in my Minecraft app. Hope you fix this soon.
