To take a screen shot, hold down the Volume Down and Power Buttons together (i.e. exactly the same time).

This will save the current screen to your phone’s memory card. They will be stored in the folder /Device Storage/Pictures/Screenshots. You can get to this folder by going to your My Files App.

It is best to avoid task killers such as Advanced Task Killer. Android is designed to automatically pre-load certain applications, even if you don’t load them yourself. If it starts to run low on memory, it will smartly unload the oldest running apps automatically.

Manually killing tasks will only mean they get loaded in memory again. Task killers can make the phone slow, laggy, or drain battery life more quickly.

Most Android devices come with an alternative way of entering text called Swype. Many prefer this method and believe it is quicker.

When any text entry box appears, press and hold the box. Then select Input method: SWYPE. Once enabled, you simply drag your finger around the keyboard moving over the letters in the correct order to spell a word.

If you want to conserve battery life, you can turn off the WiFi while the phone is asleep.

Pull down the notifications screen. Then long press on the WiFi icon. Then press the Menu or More button and select Keep WiFi on during sleep.

To quickly hide the on-screen keyboard, press the Back button or simply tap on any empty space on screen.

If you would prefer not to be told every time an Application has been updated, open the Play Store and swipe from left to right. Then select Settings and untick the Notifications options.

If you find the vibration of your phone a little too much, this can easily be reduced.

Go to Settings. Then select System – Language and input – your keyboard – Preferences. From here you can change the vibration settings.

Type a word that is not in the dictionary. The word will show up in the suggestion box to the left. Long press on the word and it will save to the dictionary.

Your phone comes with a handy widget which lets you kill all running tasks. This is great if you want to quickly free up some memory.

To use the widget, press and hold for 2 seconds on a blank part of any homescreen. Then find the Active Apps Manager widget and install it.

Once that is done, press the widget and it will show you all currently running Apps. Press End all to close all running Apps.

If you regularly visit a website you can add a shortcut to your homescreen which can be quite useful, rather than entering the web address each time you want to visit the site.

You can either do this to an existing Bookmark, or simply a page you’re visiting:

1) Open your Browser App. Enter the website you want to bookmark. You may need to wait for the whole page to load first. Then press the phone’s Menu button or More at the top and select Add shortcut to home screen.

2) Open your Browser App. Find an existing Bookmark by pressing the Bookmarks icon at the bottom of the App. Select the Bookmark and repeat the above steps.
