Why Android smartphones as users increasingly slow?

You feel your phone and your Android tablet running increasingly slow? Here are the reasons of this situation and how to fix it.

Due to the operating system and application upgrades worsening

Your Android phone is no longer used as the software has launched, which is also the reason why the machine run more slowly.

Specifically, when you get the update Android operating system, and this update is not perfect customization for your device, it can cause the machine to slow down. Or, manufacturers, network operators have additional applications in your computer, the application runs in the background (background) and delayed making machine.

Even if you have not updated, the application running in your device as well as a cause.

Whether you use the newer application or the updated version, the app seems to be getting worse.Because when developers reach faster smartphone hardware, games and applications can be customized for this faster hardware, and so they're less active than on the old device. This usually happens on all platforms.

And over time, these sites have become more severe, the application needs more RAM, the game needs more hardware.

 Solution: For this problem, there are many solutions for you. If the operating system is running slow, you may want to install a custom ROM like CyanogenMod, CyanogenMod for no bloatware software - that is, the application is added to the device by the manufacturer put on the same operating system . If your application is running slowly, look for other alternative uses lighter.

The application platform

There are more and more you can install more applications. Some applications that start up when you open the machine up and running in the background, consuming CPU resources and memory hungry devices. If you have installed multiple applications in the background, they can make your device slow down. The Android operating system provides multitasking, so apps can run in the background.

Applications running in the background can also consume a lot of resources. To check what applications are running in the background, go to the Apps screen in the settings app, and move them to another mode. If there are any applications running in the background that you do not use, uninstall them. If you can not uninstall because it was the default in the device, disable it. You do not end application, as it will automatically restart.

Solution: Please disable the wallpaper, removed the widget and remove or disable the applications that you do not take seriously. In fact, you can remove, disable all applications that you never use.

Coming full file system

SSD hard drives will slow down when they are full, so writing to the file system can be very slow.This makes the Android operating system and applications also operate much more slowly. Storage screen in the Settings app will show you the remaining capacity of your equipment, and what occupies this space.

The cache file can consume a lot of storage space if allowed to develop freely, not under their control, so deleting all the cache files can free storage space and help the file system you perform better. To delete stored data at the same time for all applications, open the Settings app, in the Storage section, scroll down and go to the Cached data, and click OK.

Solution: again, clean up the hard drive of the machine will run faster. Uninstall apps you do not use, delete files you do not need to catch and clean up files to free up memory.

SSDs do not support TRIM

TRIM is a technology that allows to improve the speed of the action recorded current data on the SSD only. The SSD TRIM support allows to improve write speeds than conventional SSDs and especially when compared to mechanical hard drives. The lack of TRIM support is the main reason Google's Nexus 7 tablet slowly over time. This error has been handled in Android 4.3, adds support TRIM. On the Nexus device, the Android 4.3 update to solve this problem.

If you use the older devices running Android 4.3 and not the machine slowly and gradually over time, you can perform TRIM by rooting and LagFix application. This application is similar fstrim run Android 4.3 in the background. TRIM is essential for SSDs - because SSDs slow down over time due to the flash memory slot must be removed before they can be recorded. TRIM will remove the slot containing the data from the deleted file, make sure everything will run as fast as possible when Android needs to burn up the slots in the future.

Solution: Root and run LagFix machine if you are using older equipment. Android devices running Android 4.3 and newer versions have TRIM support, so you can be assured of this.

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.
