The development of the Android operating system in recent years has resulted in many devices (smartphones and tablets) by different manufacturers around the world, so it is not surprising to be undecided when we are in the process of selection.
For this reason, Google has created a specially formatted web Google Phone with detailed information on the characteristics of the devices and providers that offer per country (Greece is unfortunately not included) and allows everyone to choose up three different devices to compare them directly!
The website Google Phone is available for several months but has now upgraded with the addition of several devices (and constantly add new), so the only thing to Google is to add and competing devices (iOS, Windows Phone, BlackBerry etc. ) for a more complete comparison.
