When i input a text "Abc" i m getting the text "Abc" but when i remove the character greater then inputted text and input other text (Ex. "XXX" ) i am getting backspace added in front of text.
I'm not quite sure what you mean by this: Could you give detailed steps to reproduce the issue and on what version of Unity?
I am using 5.2.1p1.If i input "Abc" the length of string is 3 and now i want to edit it so i remove "Abc" by pressing cancel button on mobile device keyboard and if i press it greater then 3 times and input another text (Ex. "XXX") now i got backspace in front of inputted text.
Thank you, I can reproduce the issue here. Could you submit a bug report? We don't want issues to get lost here on the forums.
