We all know what Android is and Droid too. At least we think we do. ‘Cause many people would say that “Droid” is just short for “Android”. True, but not entirely.
In fact there is a specific phone which Verizon offers, and it’s NOT Android. Android is (just) the operating system which powers many great smart phones today.
To make long story short, we could also say: operating system (OS) of the modern smart phones is Android. Nickname or short expression for the smart phone powered by Android can be “Droid”. If you exclude Verizon’s phone, it’s quite clear.
Hope this helps somebody
Enjoy!
