This is a mixture of AOSP and SAMMY keyboard. All latest kb features are working with aosp based kb look. It takes less space as the numeric keys are on the top row and there are graphical changes also. yes, it supports multi dpi/240 dpi. And it doesn't have the bug of double spacing if select any word from suggestions which is on latest NHI1 base.
those who are interested can try.
overwrite/ replace the new apk on /sysyem/app, change permission and reboot.
you should keep a copy of the existing one in case to revert.
special thanks to the great e-Team.
