Is the Android system included in the phone or can it be downloaded backwards???

It is generally brought by itself.

Android is a Linux-based free and open-source** operating system for mobile devices such as smartphones and tablets, led and developed by Google Inc. and the Open Handset Alliance. There is no unified Chinese name, and most people in Chinese mainland use "Android" or "Anzhi". The Android operating system was originally developed by Andy Rubin and mainly supports mobile phones.

In August 2005, it was acquired by Google and injected capital. In November 2007, Google and 84 hardware manufacturers, software developers and telecom operators formed the Open Handset Consortium to jointly develop and improve the Android system. Subsequently, Google released the source of Android under the Apache open source license.

The first Android smartphone was released in October 2008. Android is gradually expanding to tablets and other areas such as TVs, digital cameras, game consoles, etc. In the first quarter of 2011, Android's global market share surpassed Symbian for the first time, ranking first in the world.

In the fourth quarter of 2013, the global market share of Android platform phones has been reached. On September 24, 2013, Google's operating system Android celebrated its 5th birthday, and the number of devices using this system in the world has reached 1 billion.

In the first quarter of 2014, Android accounted for all mobile ad traffic**, surpassing iOS for the first time. But the operating income is not as good as IOS.

It is generally brought by the mobile phone, such as the version .And so on, most Android phones support the **update function, so that you can get the official, more stable upgrade version, if you want to flash your own phone, you can use the flashing tool to update. There are a lot of personal modifications on the general forums, but they are generally not stable enough, or the beautification mode of the kernel does not change.

Comes your own. Android system is like a laptop system, you can install XP, you can also install win7. But it was installed when it came.

The average mobile phone is 2G, which means that the Internet speed is slow! 3G mobile phones are too expensive to hurry up! A 3G phone will be about 50 more expensive than a 2G phone (just a small part).

Hovering between Google and Moto, because I don't know who made Android, Google acquired Moto, and I don't know if it's for Android, in short, it's one of the two of them who made Android, so it must be the machine they built first, so it's one of them, the best Android machine?? Wood has the best, only your preferences, MI2 MX2 N7100 19300 OPPO5 NEXUS, etc., the configuration is about the same, it depends on your preferences.
