Remove shader for minecraft on mobile phone. How does it work?

I downloaded a shader for the minecraft app on my Android.

However, my minecraft has been very, very slow since then and I don't find the graphics particularly nice either.

I have already looked under the graphics settings in the minecraft app and tried around.

Unfortunately, none of this worked.

Can someone tell me how I got a down loaded shader

(downloaded from UTK.io)

completely remove from the minecraft app on my Android?

A shader is nothing more than texture pack and can be removed in the settings on the start screen for texture packs.

In the meantime I found out for myself, but I thank you a lot for your answer
