You're very welcome, this may sound like a stupid question but is there a certain app that you use for the handwriting input method if you can explain to me how you normally use it and if there's an app I,d be quite willing to give it a try and let you know how it works out, I always use the voice typing for input so I don't know anything about the handwriting apps or software.
The own keyboard that comes by default the note 12.2, both KIT KAT as lollipop, has an option that recognizes handwriting to bring the S Pen to the screen in the area of writing, this is the functionality that I I mean in this ROM. The same is true also in other tablets Samsung, Note 8 and Note 10.1
for example, you can handwrite "hello" with the S Pen or press the "h", "e", "l", "l", "o" keys and the result is the same, I don't know if I explain correctly
Thank you
