Ques. in twitter only we can 140text characters we can write how can we write unlimited text i use android phone.
Sir, Twitter is a micro blogging site. It has a word limit set of 140 characters, this word limit is same for all platforms whether it is Personal computer, or any mobile device ( Android/ Windows / I OS).
And there is no way you can exceed this world limit.
You are not the first one to raise this concern and are affected by it. Many have requested twitter about it.
But so far twitter is all about a 140 character limited small "Tweet".
