Shaders..? 24/7/14

I’ve been playing this game for 3 years and I remember the old times when I downloaded shaders cause they were realistic and I liked them and made all of my builds look way better. But now whenever I put a shader on it just changes the sky and does nothing else but that. I have no idea if it’s just me, maybe my Minecraft is bugging but whenever I tried other and many shaders it still didn’t work. I love this game and it’s fun at times but I feel like the game would revive again if shaders were allowed on mobile like the old times. cause I mostly use this game to build houses, and I honestly don’t feel like my house is good without shaders. Either way this game is fun. I hope you can fix this issue as it’s also bothering so many people I know. Thank you!
