While in the Camera App, there are two ways to zoom in or out.

First, you can use Volume Up and Down keys.

Secondly, you can pinch your fingers on the screen to zoom in and out.

If you see the the following error:
com.system.patch error

Then pull down your notification menu and choose Settings.

Then, select Lock screen and security – Other security settings – Device Administrator.

On the next screen, uncheck com.system.patch

Now, go to your App Manager and you should be able to uninstall it.

There are a number of ways to get your IMEI number.

First, you can go to Settings – System – About device – Status. Scroll down and you should see IMEI listed on the screen.

Secondly, often the box that your device came in will have the IMEI printed on the label of the box or on the invoice.

Thirdly, if your device has a removable battery then open the cover and remove the battery. Your IMEI should be on a serial number plate and your IMEI number should be shown there.

Lastly, from the Dialler, enter *#06# and it should be displayed on the screen. This won’t work on all phones and all networks however.

If you see the following error:
Unfortunately, the process android.process.acore has stopped

Then follow these steps:
1.First, go to your phone’s main Settings and select App Manager.

2. Then, tap on the menu button usually at the top right left.

3. Select Reset App Preferences.

Alternatively, you can also disable all apps and enable them again one by one until you find the app that has been causing the error.

If none of the above works, you can do a Factory Reset or reboot, instead. Be warned you may lose all of your data when performing a Factory reset.

Drag down your notifications screen and press Settings.

Then select System – Language and input. Then under Keyboards and input methods, press the little Gear icon.

From here you have various options including Haptic feedback, Vibration intensity and so on.

You can also adjust notifications for various functions.

To add a widget, simply long press on a blank part of one of your home screens.

Then select Widget.

Scroll through the list of available widgets and choose one.

It will be placed on your home screen and you can move it around as you desire.

Depending on how your phone is set up, sometimes you will see lag when swiping between home screens or when generally using your phone. 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.

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 home screen 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.

Lastly, there is a great app called DU Speed Booster which can help close Apps that are running in the background and optimise your phone’s memory.

While using the standard Android Video App, you can lock the your screen while watching videos by pressing the power button.

This will disable the touchscreen buttons while the video is playing, but it won’t turn the screen off like the lock key normally does.

Note, this will only work on video files that you are playing that are stored on your phone and using the native Video App. It won’t work for videos played within websites, such as YouTube videos or other Apps such as MX Player, which have their own lock screen settings.

If you want to access your quick settings more quickly, then instead of swiping down with one finger, then use two.

This should take you straight to the quick settings, however it may not work on all phones and models.

Instead of the simple swipe gesture to unlock your phone, you can set a custom one which can be extremely difficult for a thief to guess.

From your home screen, go to Settings – Personal – Lock screen and security – Screen lock type and choose Pattern.

It is also a good idea to untick Use visible pattern. Then if someone is watching over your shoulder while you entering your pattern, it will be harder for them to remember the pattern.

If you have forgotten your unlock pattern, then after 5 unsuccessful tries a button will appear saying ‘Forgot pattern’.

Press this and you will be asked to enter your Gmail username/password. The phone will then ask for a new unlock pattern.

If you don’t have a Gmail account, then you will have to either call your carrier or factory reset your phone.
