When i was accessing my gmail from another country, it sent some code to my phone and wanted me to confirm it before it could let me login. there was of course an option if i did not have the phone which i think it would ask answers for some personal info and security questions. strange it did not happen on ur gmail account.
Android is Good . but i made mistake while installing apps
Never install app outside google play.
Always avoid app which comes with .app extension, outside google play
Got it .
Have you used the same username and pass on any other Bitcoin related service?
No. I made a mistake here " some android games and apps asked permission to access maill account and i blindly allowed them to access to my mail .

guys you should always have a security practice of having three email accounts. one personal(Only the most trusted people get's it, and have it secured using two factor), one commercial(Banking, Bitcoin and financial services), general(This you give it out to the world, download apps and access from a unsecured connection).
They Got my general email so ,From nowhere its also going under 2-step authentication.
