User Interface : remove EMUI, use pure android topic

Hi,

I buy this smartphone but... I think that "EMUI" is worst interface never seen on a smartphone...
So I have the fist Huawei HONOR and we could disable the "huawei interface" and get a pure ANdroid 4.0.4 interface.

I can't find same thing on ASCEND P7.
==> Do you know how to disable this interface and get pure Android interface on it ?

Thanks..
