Stock Android is now dead 
Automatic translate
At the end of May, at the Google I/O developer conference, a preliminary version of the Android M mobile operating system was presented. Many new impressive features, fine-tuning of application permissions, Chrome browser tabs inside applications, links that open in corresponding programs instead of the browser, mobile payments, support Fingerprint sensors, energy saving. Wonderful, isn’t it?
Not true. Most of what was shown at the presentation will not reach smartphones and tablets in the form in which Google intended. In reality, how Google sees the Android M system doesn’t matter. For the simple reason that in its pure form Android M will not get into smartphones that have real meaning - all these Galaxy, One and G of our world, presented in abundance in stores: https://www.creditasia.uz/vse- smartfony/ . Most of the improvements to Android M will make it to smartphones, but you can be sure that this will be later than the 3rd quarter, when Android M is scheduled to be released.
It’s time to face the truth: how many smartphones run stock Android, the way Google envisions its own system?
The answer is simple - one smartphone. Nexus 6. A device that won’t fit in your pocket. Surveys show that most users prefer smartphones with diagonals of 4.5–5.7 inches. How many of these run on stock Android? Zero.
Such a smartphone was Nexus 5. Introduced in 2013, the 5-inch device from LG was discontinued in 2015. The Nexus 5 was in many ways a dream device: half the price of other flagships, with a great display, clean Android with constant updates, a good camera, convenient wireless charging, attractive to ordinary users and developers. We can only hope that Google will offer a similar smartphone this year.
There are a few things to note about the stock version of Android.
You can recall devices that run on almost stock versions: Motorola Moto X 2014, Sony Xperia Z and a number of others, but the problem is that “almost” does not count. Key features are missing, and one of them is the speed of Nexus devices.
In 2015, lags remain a problem for the best Android devices: the Samsung Galaxy S6 slows down, the Galaxy Note 4 behaves even worse, and most other models also experience similar problems. Comparing performance with the Nexus 5 will be in favor of the device from the year before - it is faster, smoother, simply better.
It’s not limited to lags
Devices from leading brands offer an interface that is completely redesigned compared to stock Android: different icons, applications, animations, styles. It’s hard for the untrained eye to tell if it’s Android at all, and firmware makers like Cyanogen are trying to challenge Google by releasing increasingly different versions of the system.
Then we have Android One, Google’s attempt to bring a stock system with up to two years of regular updates to emerging markets. Devices running Android One have not become a real solution to the problem of stock Android: budget devices are incomparable in importance to flagships, and their low price leads to compromises in their production and operation.
The stock version of Android, which Google spends millions of dollars developing to perfection, is not available on the most advanced devices from a hardware point of view. Without the new Nexus 5, stock Android and Android M will simply be a utopia without material embodiment.
