Tip Acceleration for Android smartphones

Over time, you will feel the speed of your Android phone becomes quite slow and can not meet demand.  following article will show you some simple ways to improve speed for your phone without having to do a lot of complicated steps.

The update of the operating system and applications more severe

Software of Android phone was much different than a year ago. Did you get the updated version of this operating system, but they may not fit your device and can slow it. Alternatively, the network or the manufacturer has included in the updated application bloatwaretrong. Bloatware will run in the background and make the machine run more slowly.

Also, whether you are using the newer application versions or updates of the applications you have used a year ago, then the application will become more severe over time. Because more and more smartphone hardware improvements, the developers have created games or other applications that can integrate a complete hardware faster and they will become worse on older devices. This seems to happen on all platforms.

Solution:

Most people choose to install custom ROMs, and indeed a lot of phones that much faster. With most Android phones, there are a few or numerous custom ROM reserved for them. The most popular custom ROM now includes CyanogenMod, MIUI, Liquid, AOKP ...

Applications running in background

You probably will increasingly install more applications for your device. Some applications open when you boot the machine and run in the background, they consume a lot of CPU resources and memory occupancy of the device. If you have installed multiple applications running in the background, we can slow down the device. Also, animated wallpapers and a large number of widgets on the home screen as well as significant impacts to your device.

To check what applications are running in the background, you visit the Apps in Settings and navigate to Running.

Solution: disable the animated wallpapers, widgets relocation and removal of unnecessary heavy applications.

A file system is almost full

The solid-state hard drive becomes slow when you fill them, the same file system can be very slow if it is almost full. Storagetrong Application Settings screen will only show you the device's memory is full, and how something is occupied storage space.

Cache memory can consume a lot of storage space, so please clean the cache to help you remove the files that were installed but no longer used. You visit the Settings section of the application that uses the cache as Google and click the button to clear your cache (Clear Cache) to clean data cache.

Solution: uninstall the apps you do not use, delete unnecessary files, and delete the cache to free up storage space. You can also perform the restore status quo for the time as new devices shipped and installed only the applications you need to get equipment working like new.

Lack of adequate support TRIM

Lack of full TRIM support are the main reasons that makes the tablet Google Nexus 7 slow first time. This problem has been fixed in Android 4.3. On the Nexus device, the Android 4.3 update will help to overcome this problem.

If you own an older devices that have Android 4.3 and has not slowed down, you can implement TRIM by rooting and using LagFix applications.

Solution: please root your device and run LagFix if you are using an older device. This happens automatically on devices running Android version 4.3 or higher.

5 major technological breakthroughs are coming on smartphones

In recent years, many companies have made interesting features to attract customers. Apple integrated fingerprint sensor Touch ID on iPhone 5s. Google and Motorola to develop listening Moto X users everywhere. Meanwhile, LG and Samsung step the first step in the production of curved and flexible screen smartphones.

As the technological barriers that the mobile industry will be studied and overcome? Let's look at some of the technology can be applied to enhance the smartphone experience in the future.

Take pictures faster, focus after shooting

Imaging technology is developing at amazing speed. Here we are not talking about the camera sensor size stuffed polar body, such as the crisis in Lumia 1020.

Speaker to be upgraded significantly

Quality of smartphone speakerphone generally pretty bad, sounds no depth. However, in the near future, we will be able to enjoy better sound emanating from the speakers. HTC took the lead in this area by working with Beats Audio technology and Boomsound. Decision put 2 speakers in the front on the HTC One offers quality speaker best sound ever seen on a smartphone. However, due to restrictions on price and design, most manufacturers only equipped with a speakerphone.

Thanks semiconductor company NXP (Netherlands), we will be more welcomed improvements in quality speakerphone. TFA9895 is a class-D amplifier with high-performance algorithms to protect amplify sound sophisticated, integrated multi-band compression technology. In other words, these components provide the sound quality is improved, reducing distortion without affecting the volume and does not take batteries.

It is expected there will be more smartphones equipped TFA9895 in the coming months.Customers can expect more devices with dual stereo speakers as HTC One. Thus, we can enjoy great sound and higher quality on the phone without a headset.

Large capacity battery and charger faster

The battery is still one of the biggest concerns of most smartphone users. Today, the manufacturers continue to upgrade the screen resolution and equipped with many other features, the battery problem becomes more interesting. Li-ion battery technology currently requires large size to accommodate more power. Battery charger silicon expands and contracts when the discharge leads to reduced battery life, although the researchers are trying to bypass this feature.

Alternative energy sources and wireless charging

One of the ways to deal with problems such as battery energy review which we exploit.

Wireless Charger appeared to be a fairly long time, but have to be applied widely when people see the convenience of it. However, one of the barriers to bring wireless charging to more users is the lack of a common standard, while many other wireless charging technology together. Qi standard is now ready to take the lead, while Samsung is also developing a magnetic resonance wireless charging can operate from a longer distance. That means that smartphone in your pocket and can be charged if there is a charger near where you stand.

A further potential from the device is capable of charging. On the market today there have been the case with charger and external battery using solar energy. Solar cells are also integrated into the screen, but this technology is still in the research phase and development. Still, not a solar technology that provides enough power, but it also requires direct sunlight.

Plastics Technology

Equipment in the dream will likely fit into pockets, could open up to become a 10 inch tablet. The problem lies outside the screen panels, the other components of the machine can not be contortionist.

Graphene is the material could help realize the dream device mentioned above and being very extensive research. Graphene is a layer of carbon is very strong and flexible, can be used as a capacitor. That means we can use graphene to fabricate batteries, just make phones become more flexible. The sad thing is we still have a future that many years, but who knows mobile industry will soon witness major breakthroughs that.

5 smartphone features high-end property 'toxic' today

IPhone 5S, 1020 or LG G2 Lumia smartphones are equipped with the most unique feature on the market today, such as fingerprint recognition sensor, camera 41 "dots", or "monitor stand".

With most of the smartphones on the market possess quite similar configuration as today, a manufacturer needs certain elements to their smartphones to make a difference. These include names like LG G Flex, Samsung Galaxy Round with curved screen. However, the screen on this device is identical to the screen "contortionist" who appeared in the earlier technology exhibition.

Some other devices, such as Galaxy Note 3, is included with the stylus pen that allows users to draw, notes, very convenient. Here are 5 smartphone owners the most unique feature on the market today:

1. iPhone 5S

Apple always knows how to make its new products with practical features. Touch ID allows you to unlock, access the App Store App Store without a password. Also thanks to this feature, iPhone 5S smartphone become one of the best security available today. Some other advantages of the iPhone 5S is good quality camera with dual flash, iOS 7 interface brings a new look to the product.

In Vietnam, the 16GB iPhone 5S laptop being sold at over 16 million.

2. Asus Padfone Infinity

The highlight of the Infinity is the dock PadStation Padfone, helped turn it into a tablet immediately. This will make sense when you will not have to install 2 different devices, and even use 2 SIM. Infinity Padfone powerful integrated configuration, luxurious design and impressive battery life (when combined with the dock). With the Asus has released a few dozen test Padfone 2 in Vietnam in September last, Infinity can Padfone will soon appear on the shelves in the water next time.

3. LG G2

Not hard key design on the back of strange, the main screen "floating" is the highlight of the new G2. Combined with ultra-thin screen edges, effect "floating" screen of the LG G2 as the fullest.Currently, this is the ratio smartphone optimized display on the front area of ​​the world's best. As a number of other high-end products, LG for super fast processing speed, battery life and camera are fine. However, plastic shell design makes it less glitter than rivals. Genuine LG G2 is sold for $ 14.5 million.

4. Nokia Lumia 1020

Luia 1020 is the worst camera phone on the market today. The Nokia launched and successfully integrated 41 megapixel sensor with Carl Zeiss lens on a fragile product like Lumia expressed in 1020 constant creation of this company. However, in addition to the ultimate shooting experience, the only property Lumia 1020 midrange configuration, with dual-core and 4.5 inch screen.Windows Phone 8 platform has not received great trust is a weakness of the Lumia 1020. You will have to spend 15 million to own a genuine Lumia 1020 at this time.

5. Sony Xperia Z Ultra

Phablet a 6.4 inch screen with a thickness of only 6.5 mm, waterproof design, anti-dust is not a priority of the Xperia Z Ultra Vietnam. With a business-friendly products such as Xperia Z Ultra, without the ability to note stylus (just pencil or pen) was the most notable. Currently, it is also the first smartphone to allow users to type notes with pen often, instead of the stylus. Besides, Z Ultra also integrates powerful configuration, except for camera 8 megapixel resolution only. Price of Xperia genuine Ultra Z is 18 million.

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.
