Can you please advise what's the difference between GM1900 vs. GM1903?  In particular, does the GM1900 8G/256RAM) come with:

1)  Two prong 110V plug not Indian or other country plug)?

2)  Does this version ship with Oxygen OS or Hydrogen OS?

3)  What is your warranty for phone when purchased directly from your site?

Your replies are appreciated!
