[Q] Can't change Input Method

[ammend]

I have a rooted S5 running alliance rom with the Apex launcher and I cannot enable any other keyboard. I've installed/unistalled multiple keyboards and when I change the input method it will get ticked and then switch right back to the stock keyboard. Any have this happen or have a fix?

Never had that happen but try freezing the stock keyboard then try using a different one.
