OK, as "Huawei Ascend Y511" user hopefully already knew how to enable "Developer options".
--Tap 'Build number' 7(seven) times in 'Phone Settings > About phone' and What!!.. "Developer options" will appear in phone settings. (Don't know if same with other huawei models.)
Well, what i find out is almost same thing to do which bring up "Developer options". But it's not 'developer options'.
just for Fun/sharing, nothing more than a "trick".
-- In same 'Phone settings > About phone' there is " Android version". What if you Tap it for 3(three) times.
Lets Test it out....
Let us know, on what other Huawei phones this work out!!!!
Will try to post whenever i'll find something New/Interesting....
