Nokia X - a combination of Windows Phone and Android

The first Android phone from Nokia has officially introduced. With the appeal of each phone manufacturers lead the world, the Android operating system and special relationship with Microsoft, a lot of people are curious about the Nokia X experience that brings.

Here are the views from TheVerge.



It's not a device that the Finnish phone company has brought to three the MWC 2014 Nokia X running Android. Rumors appeared on models from 12/2013 but many people are skeptical especially when Nokia bought by Microsoft. XL equipped with Nokia's largest display, 5 inches, with price 150 USD Nokia X and X + also owns 4 inch screen with price and $ 122 respectively 136 USD. This is not a competitor of Samsung Galaxy S5 unveiled Apple iPhone 5S or equipment not owned by configuration cult, high-end features. Nokia X attracted special attention because it is the first Android device from Nokia.

Nokia ever signed a cooperation agreement with Microsoft about using Windows Phone OS but this did not stop the carrier testing Android operating system accounted for the largest market share today. Unlike most Android devices, Nokia X uses a completely new interface similar to Amazon did with the Kindle Fire but still take advantage of the services and bring Android ecosystem. Specifically, Nokia X interface of Windows Phone slightly bring with simple square but a lot will run Android applications, something that Windows Phone is lacking. Nokia X is not authorized to access Google Play app store and install software such as Google's Gmail, the Chrome browser, maps ... However, we have also created a separate app store for third-party registration download.



Nokia X shares many design templates on the Lumia 520 running Windows Phone operating system. Both seasoned design with striking colors and jointly own 4-inch screen. Nokia also equipped with a modest configuration for the first Android phone with its dual core processor speed of 1.2 GHz, 512 MB RAM, 4 GB of internal memory and a 3 megapixel camera. Nokia X + has high memory capacity and more. Nokia Android devices support 2 SIM and in appearance, it is little more than the Lumia 520 omitted three capacitive touch key and camera key. With Nokia XL, the difference was clear when the machine is equipped with 5-inch screen, 5 megapixel main camera with autofocus and 2 megapixel camera.

Regarding software, just feeling strange experience but also "a bit confusing." hard keys allow navigation only click once to go back and keep to the main screen. Nokia has created Android devices that interface with the same squares on Windows Phone. All installed applications will be displayed instead of being arranged in each folder. However, users can change the size of this square. Nokia also customize notifications when items using features from Fastlane brought to Asha line. Fastlane will gather all user activity recently in a single interface.

Nokia X experience that brings different from what firms do with another Windows Phone device, including cheap line. The Verge says, users will feel "frustrating, slow interface response and have a long wait." These heavy applications like web browsing will "challenge your patience." The third-party applications such as Facebook are no different than the version on Android and efficiency is also quite bad. The only unique navigation keys on the Nokia X quite confusing when Android needs three buttons and the Windows Phone as well. Users will need more time to get used to new users.

One of the reasons why Nokia X high performance is not due to hardware fitted quite low compared with the current Android devices. There is a similar configuration but Nokia Lumia 520 X running Android 4.1.2 Jelly Bean was released from 10/2012 and this is not the OS is optimized for low profile devices. If you are using Android 4.4 KitKat, experience can be better than the new version uses less memory than 16% of Jelly Bean. The old Android users also pointed out that Nokia has cherished and Nokia X testing for quite some time.



The question many people ask is why re-launched Nokia X series running Android? The company said, X is designed to combine the flexibility of services, applications, features of Android, Microsoft and Nokia. The launch of Android phones seem to not be prevented from Microsoft even after acquisition by these devices will help users access to its online services as OneDrive, Outlook, Skype and MixRadio, Here the map. Nokia X will install the application on the factory immediately, Bing also become the default search service. Clearly, Google is developing a strong ecosystem through its online Android and here is how to do the same.

Nokia X was announced less than a day after Microsoft unveiled updates will appear on Windows Phone 8.1 which the company said will be compatible with the low-profile design. Windows Phone behind Android but Microsoft is trying to make a difference. What Nokia X shows you this is just a test project with the efforts of a group of engineers. This happened when Nokia launches N9 device then no successor yet. Nokia X also have to build its own app store and make sure the new software would appear difficult at the same time as on Google Play.

At the press conference, curator of the PC, phone and tablet Microsft, Joe Belfiore said: "We are excited that Nokia has made some but some do not," when asked about Nokia X was released.There will be much to talk about but the project launched Nokia X phones running its Android actually is only a test.

Android 4.4: important turning point run smoother and increase smartphone battery life

Throughout history, rapid growth and prolong choppy 5 years, compared with operating system version first, almost every aspect or feature of Android 4.4 has been changed. Every time Google releases a new version of Android, which are updated or upgraded fairly comprehensive, but everything except the most important: Dalvik. Accordingly, the virtual machine is responsible for running most Android apps remain like this since the first day. And to this point, Dalvik has revealed signs of age, slowness is visible. To keep pace and meet the demand for higher levels of users, Google has decided to use ART (short for Android Runtime) on the Android operating system version 4.4 to replace Dalvik KitKat. ART first version integrates with Android 4.4 can accelerate applications by 100%, while the complete version will be even better.



When you run the software on electronic devices, such as PC or smartphone, almost always your machine to run the compiler "compiled code". The compiler is responsible for shifting the source code written in a high level language into object code or machine language which can be executed directly by a computer or by a virtual machine. For example, if you open an EXE file, you will see the compiler "gobbledegook" help CPU can perform load cycle to start the application. Windows, web browser, Crysis 3, Linux, iOS apps are all examples that use the compiler.

Next, we are a different kind of code interpreter called "interpreted code" with many different types, but have one thing in common is that they can not be done directly by the CPU load. First, the interpreter must be decoded into machine code by a process called translation system JIT (Just-in-time). For example, the most popular of the JavaScript interpreter, according to which, the web browser will compile / interpreter code when a user visits a web page using JavaScript.

In addition, a typical example of the Java and Dalvik interpreter is essentially a "Google version" of Java. With Java, developers can write applications once only, and then convert it into the language of the hardware platform through an "interpreter" named Java Virtual Machine.Explains a lot, but we can generally shortened to the point that Google has decided to use the Dalvik virtual machine for Android app. This way, a developer can write a single application Dalvik and be assured that it will run on smartphones, tablets, TVs or other devices.


The chart shows the performance of JavaScript (red / green) than when compiling the source code (orange).

But now, the shortcomings of the interpreter "interpreted code" is it really slow. For example, JavaScript can be up to 20 times slower than the same code compiled with C or C + +. Java / Dalvik is not too slow, but can not compare with the speed of the original compiler. In many cases, especially with the processor's advanced 4, the speed difference is very clear. We can not be blamed entirely for the cause Dalvik Android devices lag or battery power, but this is certainly an important factor causing this. Basically, the Dalvik interpreter takes longer to decode and to calculate more CPU, so it directly reduces the battery life and smoother overall mobile device.

Android Runtime - ART

While using session Dalvik JIT (Just-in-time) to decode, ART on Android 4.4 using process AOT (Ahead-Of-Time). First visible effect of shortening the time it is decoded meaning shorten boot time, help applications launch time 2 times faster than the old Dalvik process. By activating ART, each Android application will be compiled into native code when you install it. Then, when you launch the application, it will act as a root application installed on your computer.



Currently, ART is still in the experimental stage, but you can still activate it on the machine running KitKat Nexus by going to Settings> Developer options> Select runtime, then just wait for the machine to reboot. This change also accounts for part of the machine capacity (increased about 10% to 20%) because your code is still being finalized. Maybe you will not notice the change of AOT for small applications, but for larger applications, the delay will be remedied. In addition, the main advantages of ART is to allow Android developers continue to write code and run on multiple handsets with different hardware configurations.



ART has been tested and Vietnam expressed its advantages: increased battery life, smoother handling and speed up application open. Once ART is fully developed, the current Android OS can be "disappeared", but instead is a new operating system faster, more powerful and more Vietnamese priority. Benefits are more easily seen when you run compute-intensive applications such as photo editing or video editing. At the same time we can hope for a smooth run Android as what iOS or Windows Phone has done.
