How can I change the keyboard settings ?

[AC Question]

I have change by accident the size of my qwerty keyboard (device p8 lite) and it sucks!i've tried everything but nothing helped!
P.s I don't want to use other keyboard but even if I do,the size is still wrong in other apps,in the calling pad,in the pin and everywhere!HELPPP

Welcome to Android Central! So you've already looked through all of the keyboard app's settings? Did you change the size of the entire keyboard, or the size of the letters on the keys only?
