Android JellyBean stock keyboard capitalizes first letter of word before question mark On my Samsung Galaxy Tab 3 running Android JellyBean 4.1.2, when I add a question mark after a word, the first letter of that word gets capitalized. Do you know why this happens and how it can be Solved? See the last Sentence? It's happened there too.
All I can see are lower case letters. It might be a bug with  your Samsung keyboard software. You could try updating your os if it is the case or you could try other apps for writing like SwiftKey for example.
