To install any app in your Android mobile phone you need a Google account. In simpler terms, you need a Gmail email id, something like yourName@gmail.com The very fact that you are using your mobile phone means that you do have a Gmail email [ ignore the alliteration! ]. But you have no clue what your email is? Probably someone else had setup the phone for you? Here’s how to view your email id:
1) Please go to Settings and tap on Accounts
2) In this screen please tap on the Google icon
3) Voila! Here is your email id right at the top of the screen!
That was not that difficult, was it?!
