How to improve the performance of your Android smartphone or tablet

Android as an OS has evolved quite a bit over the past few years and there are a lot of tools at users disposal to optimize the performance of the smartphone. The Android OS has the ability to give users an acceptable experience even on an entry level smartphone. Manufacturers at times skin the OS with their own UI and also offer some preloaded apps that may often be nothing more than bloatware. The flexibility and customization options that Android offers sometimes works against it as it may make the smartphone/tablet lag, slower and a battery guzzler.

To help you achieve a state of optimum battery life and performance on your Android device, here we list a few tips and tricks that can help you get the most out of your smartphone or tablet.

If you aren’t using it, delete it!

Some Android devices come preloaded with a bunch of apps. If you pick up a smartphone or tablet from Samsung, HTC, Sony or some other manufacturers, you will get a preloaded skin on it along with a few preloaded apps. Some of these apps may consume memory, stay active in the background or just consume storage space. If you aren’t going to use these apps, it makes sense for you to delete them. This will not only help you get some storage space, but also make the phone run smoother as well. You can uninstall apps from the Settings>Device>Apps menu.

If you have purchased a few apps and are worried that you will have to repurchase them once deleted, don’t worry. Once an app has been purchased, you can delete it and download it as many times as you like. All you need is to log in with your Gmail account (the one you used to purchase the app). The only downside is that you will lose any data that you have saved via some of these apps.

Update on a regular basis

App developers as well as smartphone or tablet manufacturers release updates on a regular basis. These updates may bring a new version of the OS to your device or may update the firmware to give you better performance. Developers also release updates for the apps on a regular basis. These updates help optimise the performance of the apps as well as make them more efficient. Updating your apps and device on a regular basis will affect the performance.

Updates for apps can be accessed from the Google Play store. To update firmware/OS , you can access it from Settings>System>About the Phone>System Update.

Fewer widgets

One of the best features of owning an Android device is that you can customize the available home screens with widgets and live wallpapers. The downside to this is that they are battery guzzlers. You would do a lot better to have a static wallpaper and if you aren’t using a widget, it makes sense to remove it, as widgets not only consume battery but data as well while updating.

Widgets and live wallpapers consume not only the battery but the memory of your Android device as well. Switching them off means that the device will become smoother to operate. A long press on the home screen will bring up the wallpaper and widgets option on most Android devices for you to customize.

Transfer apps to the SD card

One of the biggest problems, especially of mid-ranged Android smartphones and tablets is that the built-in storage is really low. There are some apps that cannot be transferred to the SD card, but most of the apps available on the Play store can be moved to the SD card.

It is easier to clean up the memory card by deleting left over folders from uninstalled apps and also simpler to transfer data from your PC to the device.

Background data and connectivity options

The beauty of Android is that it is very easy to sync your contacts, apps and other information seamlessly between devices. Unfortunately, the background sync depletes the devices battery life in a jiffy. Disabling background sync will help you save on the battery life of the smartphone. It is easy to manually sync your Android device with a simple click of a button. You can also enable selective sync if there are apps and information you would like updated all the time.

On your Android smartphone or tablet you have a bunch of connectivity options such as 3G, Wi-Fi, Bluetooth and GPS. Sure, all these connectivity options are great to use but you won’t use them all the time. It makes sense for you to disable these functions when they aren’t in operation. Switch on the Wi-Fi when you are in a Wi-Fi zone and switch it off when you leave it. When you aren’t using the Internet on your smartphone, it makes sense for you to switch to 2G as 3G is very power hungry. GPS and location services too can be switched off after you have checked-in or finished using Google Maps.

Setting the display brightness to auto will help you save the battery but it is better if you manually control the brightness and set it to as low as you’d feel comfortable with. The screen is one the biggest battery drainers and if you are someone who has a behemoth of a smartphone with a large display, you will see a noticeable bump in battery life with lowered display brightness.

You can add a power control widget on the home screen that lets you control the Wi-Fi, Bluetooth GPS and other settings with brightness controls. Some smartphone makers give you these options in the drop down notification area.

Root your Android device

This option isn’t advisable for all but if you are someone who wants to unleash the full potential of your smartphone, there is no better option than rooting.

Android is built on the Linux kernel and like any other Linux-based OS it also can be rooted. The advantage of rooting is that you have administrator level access on your phone/tablet. If there are apps on your device that can’t be uninstalled through  traditional means, you will be able to get rid of them after rooting the smartphone.

Rooting your phone also gives you the ability to flash it with custom ROMs. This means that you can customize the phone to work the way you want it to. Put simply, rooting helps you enhance the performance and battery life of your phone. If this sounds like something you’d like to do, check out our comprehensive guide to rooting Android smartphones.

When Google launches a new version of Android, it takes quite a bit of time to come to third party smartphones and tablets. Rooting your smartphone gives you the ability to install and have access to the latest version of the OS days after its launch.

Third party apps

If you are someone who has already tried the above options and still wants to do more to get the best performance boost from your Android device, you can resort to some third party apps available on the Google Play store. You have many free apps to choose from but there are a few paid apps worth investing in as well, depending on your requirement.

Battery boosters

Typing “battery booster” in the Play store will give you a hundred apps to choose from. These apps help you boost the battery life of your smartphone and also help you monitor and see what apps are consuming the most amount of battery. Some apps also give you options such as power mode, restrictive mode and battery saver mode. Each mode cuts down activities such as data, Wi-Fi, brightness, background sync and more to conserve battery.

These apps are handy if you are someone who doesn’t want to manually control the functions of your smartphone. They also help monitor the health of the battery on your smartphone.

Clearing memory/Boosting apps

If you have a smartphone that has low RAM, you will notice quite a bit of lag, especially if you multitask heavily. There are a bunch of apps available on the Play Store such as Clean Master, Memory Cleaner, History eraser and more. These apps help clear the cache and also help free memory being consumed by apps in the background at any given point of time.

If you have a large library of apps and are a heavy multitasking user, then these memory-freeing apps do make sense for your Android device.

All-in-one monitoring apps

If you don’t want a different app for monitoring each function of your smartphone, you can always resort to some all-in-one apps such as Elixire 2, System Tuner, Android Assistant, Greenify and many more. These apps not only help you improve the battery life of the smartphone but also help in enhancing the performance by managing the apps and memory usage of the device.

How to move files and apps from phone to expansion card in Android

In our Android smartphone reviews we often comment that a handset has only 8- or 16GB storage, but can be expanded using an SD card. The ability to use portable storage to expand the capabilities of a smartphone is an absolute boon, but it’s not always as straightforward to use such storage as you might think. It is desirable, however.

Keeping files stored on SD card rather than phone makes it easier to swap them from device to device. It also keeps your phone storage free for things such as the OS and apps, which may keep things moving along quickly on an older handset.

Moving apps from your phone to the SD card is almost always difficult, and often impossible. And it isn’t always as straightforward as it might be to move files from your phone’s storage to the SD card.

Because each iteration- and each manufacturer’s version of Android can be so very different, we can offer only general advice here. But here is advice for if you have an Android phone or Android tablet and you want to move apps or data from the phone to the SD card.

How to move apps from Android phone to SD card

Let’s address the main issue first: there’s a very good chance you might not be able to do this. Because of the way they mount SD cards, many Android manufacturers won’t let you run apps from the SD card – you can’t on some of the Galaxy phones, for instance. In part this is for performance reasons, and in part because the SD card is outside the walled world of your Google account which may make permissions tricky.

This isn’t the case with all Android phones, however. If you can move apps to your SD card, the process is likely to be something like this: go to the Apps menu, find the app you want to move. Then through that particular App’s settings, select move to SD card. See also: Group test: what’s the best smartphone?

How to move files, photos from Android phone to SD card

Transfer Data to SD cardIf you can’t move apps, you can definitely move date from your phone storage to the expansion card. By default files such as music, movies, photos and documents will save to the phone. We’ll explain how to set each type of file to save to the card a little further on. For now let’s concentrate on moving files.

First of all look in your phone’s app menu – is there something called ‘File Manager’ or similar? If so, you are in clover. If not, don’t worry – there are plenty of free third-party file manager apps on the Google Play app store. One we like is ASTRO File Manager.

Using such an app you can browse through the file structure of your handset, find the file or folder you wish to move, copy it, paste it into the new location on your SD card, and delete the original.

But here’s a simple pro tip: you don’t even need an app if you have access to a PC and a USB cable. That being the case you can mount your phone or tablet like a USB drive on your PC. Click into it from the PC and you’ll see the file structure, like any other portable storage. Then simply drag-and-drop files to the SD card. This ability to see and utilise your phone as USB storage is one of the key advantages of Android over iOS.

Transfer Data to SD cardThere is one other possibility that is worth considering. In some recent versions of Android, if you go to Settings > Storage, you’ll find an option called ‘Transfer data to SD card’. Here you can select or all data or certain types of file (photos/music etc), and transfer them from the phone to the SD card via a single click. Do this periodically to keep your phone’s storage free.

How to save files direct to SD card on Android

Finally, here’s how to set up your Android phone so that new files automatically save to the expansion card. Select the app you use for that type of file – for instance ‘Camera’ for photos. Then go to Settings > Storage or similar. There should be an option called something like ‘Save to SD card by default’. Enable this option

BBM for Android & iPhone

If the arrival of landing page on BlackBerry’s company website is can be used an accurate indication of things to come, the launch of BBM or BlackBerry Messaging for Android and iOS could be near.

A special page for the upcoming applications arrived earlier today. Unfortunately, the landing page doesn’t actually offer any more details about the iOS and Android variants of the application. Instead it only asks users to submit their email address so that BlackBerry can provide them with an email notification the moment BBM for Android & BBM for iOS are available.

BlackBerry first announced that it would be bringing its BBM messaging service to both Apple and Google’s mobile operating systems at its BlackBerry World show this past May. Since then screenshots of the Android variant of the application have leaked, depicting an interface that will be familiar to any user who has had experience with BBM on BlackBerry’s BlackBerry OS.

Users can now leave their  email address and get a notification on when BBM for Android and iOS arrives.

Users can now leave their email address and get a notification on when BBM for Android and iOS arrives.

It is generally believed that BlackBerry is making the application widely available so that its users can enjoy communicating with their friends on iPhone and Android without having to use other messaging clients. By making the app and service available, BlackBerry is also hoping to attract BBM on Android and iOS users to its BlackBerry 10 operating system.

While the tactic might have worked just a few years ago, lately each mobile operating system has consolidated around its own built-in messaging service, a few of which are already freely available. For example, iPhone, iPad and Mac OS users are able to communicate with other users on Apple’s platform using the freely available iMessage app. Meanwhile Google’s revitalized Hangouts app is available to all Android users, desktop PCs and on iOS. For its part Microsoft’s Skype is available on nearly every platform.

Every device running BlackBerry 10 including the BlackBerry Q10, BlackBerry Q5 and the BlackBerry Z10 all come with BlackBerry Messaging built-in.

If the recently released screenshots are correct, users will have to sign up for a BlackBerry specific account before they can use BBM, however there doesn’t appear to be any sort of fee attached with using the service.

India’s first cyber forensic lab set up in Tripura

India’s first Cyber Forensic Laboratory (CFL) has been set up in Tripura, an official said Monday.
The lab, established at the Tripura High Court will provide court case related information.

“From the CFL, automatic SMS alert would go to both lawyers and the litigant about the fate of the court case. If any lawyer or the petitioner remains absent on the day of trial, the SMS alert would go to all concerned,” a law department official told IANS.

Supreme Court judge Justice Madan B. Lokur, who was earlier the chief justice of the Gauhati High Court, inaugurated the CFL on Sunday.

“We want decentralisation of legal services across the country. It is difficult to control everything from Delhi. High courts in the states would look after the lower courts to dispose the pending cases in the quickest possible time,” Lokur said.

“A National Judicial Data Grid (NJDG) is being developed under the Supreme Court’s supervision. All information about legal services, court cases and judicial actions would be available from the NJDG,” Lokur said.

The NJDG would be fully operational by January 2014.

“So far, 13,000 judicial officers, including judges, have been trained about the e-court system and to equip them with the ongoing modernisation of legal services. Several thousand judicial officers would be given training about this new system,” Lokur said.

To conduct an online trial, video conferencing systems are being expanded across the country, he said.

“Under this system, any judge or lawyer sitting in the court can talk to the accused lodged in jails”.

Lokur first introduced the e-court programme in India when he was a judge in the Delhi High Court. He was a pioneer in introducing video conferencing systems between the Delhi High Court and Tihar jail in 2007.

Of the 620 district courts in India, 140 have created their own websites to provide case related information, he said.

“All e-court schemes would help judges take appropriate action for quick disposal of pending cases in various courts,” he said.

“With this new system of trial and administrative works, the litigants will be immensely benefited. It will save both time and money to get quick justice and prompt disposal of cases,” Lokur added.

Tripura High Court Chief Justice Deepak Gupta and Justice Subhashish Talapatra also spoke about the lab.

Separate high courts were set up in Tripura, Meghalaya and Manipur in March.

The seven northeastern states – Assam, Tripura, Manipur, Meghalaya, Mizoram, Nagaland and Arunachal Pradesh – were earlier under the Gauhati High Court with benches in the state capitals. Sikkim had a separate high court.
