Salloum wroteHuawei makes some great phones but their UI is really crap in my opinion. It's one of those "hate it or love it" kind of UIs.
It's not just the UI. I got a G8 and the EMUI got me so mad . You wouldn't believe how slow it ran on a snapdragon 610 octacore !
I ended up flashing CyanogenMod 13 on it . Now it's as fast as my old Xperia Z2 (Snapdragon 805 - a beast this one) . But for 250$ .
Seriously the best thing you can do with huawei is buy a cheap one , and flash some custom ROM on it :p
