A micro SD card is a removable mobile memory card, that can be installed in a mobile device for extending the internal storage capacity.
1. To install the micro SD card, carefully remove the back cover of your device (some devices may not require this step).
2. Remove the device’s battery (some devices may not require this step).
3. Locate the micro SD card slot and just slide-in the card with the gold contacts facing down.
4. To remove the micro SD card, just slide-out the card carefully to remove.
5. Reinstall the battery and the back cover (some devices may not require this step).

1. Uninstall any apps you do not use: If you have apps you do not use but they are still on your phone, it is better to remove them and avoid having them run automatically in the background and use up your phone’s resources like memory, processing power and battery. Remember that the less internal memory that is available, the slower your phone gets. There are several apps available online at the Google Play Store for removing unused applications; one such app is App Eater.
2. Reduce the number of home screens: Limit home screens to two or three. You will realize this quantity is more than enough and you will always have the apps you use the most on hand.
3. Disable animations: When using your Android device, animations appear when apps are opened and closed. These animations improve the visual appearance of the apps; but by disabling them, the apps will load almost instantly. Disabling the animations is simple, just go to Settings>About device>tap on “Build number” quickly seven times and tap the back icon. In the Settings menu the icon “Developer options” will be visible. Tap on “Developer options” and scroll down to the “Drawing” section. Tap on “Window animation scale” and select “Animation is off”. Do the same for the options “Transition animation scale” and “Animator Duration Scale”.
4. Use static wallpapers: Live wallpapers look very nice with their changing colors and images, but they take up resources and slow down your device. Selecting static wallpaper will free up system resources and improve the performance of your device.
5. Reduce the number of widgets:Having an open widget is like having an open app; it will consume resources and battery power. It’s advisable to remove all unnecessary widgets.
6. Use only one app for each function: Your device may have several apps that perform the same function, for example, an email app, Twitter client, music player, etc. Choose the one you like and delete the rest.
7. Clear the Cache and Delete Junk Files: One of the best apps for this task is Clean Master. This app lets you: see how much space is taken up by your files, clear the application cache, and delete junk files or empty folders. This is a quick and easy way to clear your Android device of unwanted files.
8. Reduce the number of accounts being synchronized: Within the Settings sections there is an option called “Accounts” that contains the details of all the accounts that are synchronized periodically on your device. The synchronization process consumes your device’s battery and processing power. If you do not use an account or do not require constant synchronization, it is recommended that you disable automatic synchronization for that account.
9. Use ART: ART is a new Java-based library that manages all your smartphone’s functions. Using this library will increase your smartphone’s performance and improve battery consumption.
10. Perform a Factory data reset: We all use our phones 24/7 without giving it a rest. If you notice that your device starts working strangely, is operating very slowly, or the battery life is too short a good solution may be to reset your device. Go to SETTINGS>BACKUP AND RESET>FACTORY DATA RESET. Once the process is completed your device will be restored to the original factory settings.
