If you want to move a widget from one homescreen to another, simply press and hold on the widget. Then drag it to the edge of the screen. The next homescreen will appear. Then, just drag the item to where you would like.

Recent Android versions use a special mode that hides all Android related visuals. The mode is called immersive mode and it essentially means certain Apps have the whole screen available.

Sometimes this can be annoying however and you want to see the time, signal strength or batter indicator.

To temporarily leave immersive mode, simply drag down your notifications screen and the phone will exit immersive mode so you can see other features.

To change the backlight screen timeout, drag down your notifications screen and press Settings. Then under System select Display. Then under Screen timeout you can set the screen time out duration.

You can also tell the phone screen to always stay lit when it is plugged in via USB. Go to Settings – System – Developer Options. Then check Stay Awake.

Note: Developer Options is not always enabled by default. To enable, go to Settings – System – About Device. Then tap on Build number 7 times to enable this secret option.

To add a widget, simply long press on a blank part of one of your homescreens. Then select Widget. Scroll through the list of available widgets and choose one. It will be placed on your homescreen and you can move it around as you desire.

There are a number of ways, as below. The first two of these may be disabled on some networks/carriers or Android versions however.

1) Go to Settings – Device – Applications – Application Manager. Then swipe from right to left until you are on the All screen (at the top). Then scroll down to Contacts Storage – Clear Data.

2) Go to Contacts. Then hold and press on a contact. Then choose the All option at the top of the screen and select Delete. .

3) Go to Settings – Personal – Accounts and sync. Then press More at the top and choose Disable auto sync. Then go to Gmail (or an account that your phone syncs with) and delete all of your Contacts from there. Then re-sync your phone.

4) Download an App called ‘Delete All Contacts’ and use that as a last resort.

The methods above will delete contacts from the Phone only, not the SIM card.

If you would prefer to correct your own mistakes, then go to Settings – System – Language and input.

Then select the keyboard you are using and press the Settings icon again.

You should be able to find a predictive text option on this screen.

Android manages Apps very well and some Apps do not have the option to close them specifically. Normally the App will stay running in the background and only close when many other Apps have been opened.

If you do want to close or terminate an App, then press and hold the Multitasking key on your phone. On some devices you may need to long press the Home key. Then you can swipe the Apps off the screen to close them.

Even after doing that, there may be some apps still running in the background.

To close these apps, go to Settings and open Application icon, from here you can open applications list and tap on any app you want to close.

From here simply tap on force stop and application will stop working in background.

To set your voicemail number which allows your phone to automatically input your voicemail password, then open your Dialler App.

Then press the More or Menu button and choose Call settings. Then scroll down to Voicemail settings and set a Voicemail number (you might need to check with your carrier for the correct number).

Depending on your carrier you may have to enter the series of steps required to go through the voicemail menu, for example: *86,,yourpassword# (a comma inserts a pause).

When using your Calendar App, you will normally be in Month view. To quickly switch to Year view, you can pinch the screen to zoom out.

This is useful if you want to quickly jump backwards or forwards through a few months at a time.

To go from Year to Month, you can do a reverse pinch.

If you are running low on phone memory, you can look for your largest applications to uninstall.

Go to Settings – Applications – Application manager. Then swipe from right to left and select Running.

From here you can see which applications are taking up the most memory and close them.
