When taking photos or videos, tap the screen where you want to focus on. The phone will automatically adjust the settings to improve the image or video

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.

Android manages your applications so if the phone is running low on memory, it will close the oldest running App.

If you do need to manually close an application go to Settings – Applications – Application manager. Then swipe the screen from right to left until you are on the Running screen.

Then choose the application you want to stop and select Force Stop.

Android has a feature allowing you to update Applications automatically. This is turned off by default, but you can turn it on.

Open the Play Store App and press the Menu icon in the top left of the App. Then select Settings and in Notification section you can turn Auto-update apps on.

From here you can chose to do this over WiFi only or using your Data connection.?

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.

Depending on how your phone is set up, sometimes you will see lag when swiping between homescreens. There are a number of things you can try to fix this, as follows:

First, try restarting your phone. This will fix many problems.

If that doesn’t work, then remove any Widgets that pull data to the phone, such as Twitter, Weather widgets etc.

If you have Live wallpapers turned on, then try turning them off by going to Settings – Wallpaper, then changing to a different Wallpaper.

Go to Settings – System – Developer options – Window Animation Scale and Transition Animation Scale. Try changing these to 0.5x (or even 0).
(you will need to unlock Developer options if you can’t find this. Use the search form on this site).

Sometimes the problem can be with the phone or operators skin or launcher, so try going to the Play Store and downloading a third party launcher such as Nova launcher or Go LauncherEx. Note: you will need to re-create your homescreen shortcuts, but they are both great launchers.

Another tip is to always press the Back key instead of the Home key when leaving Apps. The Back key will often close the App properly, while the Home key can leave it running in the background.

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.

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.

The phone has the ability to send quick response text messages if your phone is ringing but you can’t answer it.

To change these, go to your Dialler App and press the Menu or More button. Then select Settings – Call rejection.

From here you can add or edit your reject messages.

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.
