Keyboard in alphabetical sequence (ABC layout keyboard) I am considering buying a Samsung Galaxy phone. Is there an option (either basic phone function or a third party app) which provides a keyboard in alpha sequence, that is ABC layout instead of QWERTY?
The stock Android keyboard doesn't have ABC layout. However, there are some keyboard apps which have ABC layout. SlideIT English - ABC pack is an example. You can find some more if you  search for "ABC keyboard" on Google Play.
