not working deferred technical preview

Hello, I activated the related experience settings in my world and tried this new feature of the Minecraft game with shaders that support this feature, and every time I enter the settings and activate the deferred technical preview option, it does not work and is thrown out of the game , will this feature be optimized for Android? Will it solve the problem?

and my processor and phone; Motorola one action, GPU renderer mali-G72, GPU vendor: ARM, ram = 4 gb, storage = 128 gb ,

I know it should work on my system too, because I've played games with shadow graphics and a lot of content, and it worked, and I think it should be optimized for Android, because it makes the game much better and nicer. does, this is a new feature and I think it should be optimized, and it should work well on game objects, there are many things in programming that can be done to improve and optimize, please improve this feature, and even It can automatically disable lighting in places where we don't pass by and can't see, and in places in a certain range and in sight, I have played the game called Ark mobile, despite its bugs, with relatively good graphics and A lot of content and lighting and shadows worked!
