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.

If you find that apps are slowing down your device or consuming unnecessary memory or batter life, then try downloading an App called DU Battery Saver or DU Speed Boost which are great for optimising the Apps that are running.

No one likes nuisance phone calls, so here’s how to deal with these on your phone.

The first option is to block all anonymous calls, although this may block some calls from people or companies that you do want to allow, so use this carefully.

To enable this, go to your Dial App press the settings icon in the top right. Then choose Settings.

Then choose Block numbers and then Block unknown callers.

Secondly, if you’d like to block calls on a case-by-case basis, then follow these instructions:

First, wait until you’ve been called by a nuisance number. You can either answer and verify who they are, or when the phone is ringing, do a quick Google search for the number (ideally on a PC, otherwise you may need to switch between apps on your phone).

Often the number will come up on Page 1 of Google and be reported as a nuisance call number. You can often tell pretty quickly because the number will have many negative review.

Then once the phone has stopped ringing, go to your Dial App and then select Log to find the number on your recent call list.

Find the number that called you and press on it. Then in the top right, select More and select Block/unblock number.

To manage this list, then go back to the first screen of your Dial App and press the settings icon in the top right. Then choose Settings.

Then select Block numbers. From here you can see which ones to block or unblock.

From now on you will see that you received a missed call, however the phone will not ring and you won’t be bothered by the caller.

There is a hidden Android Easter egg on the phone that Google has built into your device.

Go to Settings. Then scroll down to About device or About phone.

Then select Software info and find Android version.

Press this 5 times.

Once you see something on the screen, you can then rub the screen with your finger to produce another surprise. If rubbing doesn’t work then try tapping with your finger. A combination of the above should work. If not, then try different things. That’s the fun of the Easter egg.

By the way don’t expect to see an actual Easter Egg. That is just the name given to things hidden inside software or operating systems.

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

To copy files between your phone and PC, go to the Android Play Market and search for one of the following top rates Apps:

Air More
Airdroid
Wi-Fi File Transfer
Portal

These are all useful Apps which allow you to connect your phone to your PC wirelessly, allowing you to move files and many other things.

Alternatively if you just want to copy using USB then simply plug the standard micro USB cable into your phone and it should appear as another drive on your PC.

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 Apps.

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!

If you are browsing a website and want to see the HTML source code behind the page, then Android doesn’t offer you the ability to do this by default.

There is however a handy App called View Web Source which can be installed. Whenever you want to view the HTML of a web page, you just press the Menu – Share – View Web Source.

You can then browse the code or copy the content into the clipboard.

There are some other Apps that are similar to this if it isn’t what you need. Try searching the PlayStore for HTML Viewer or similar.

When browsing on your phone you may notice images are quite blurry. This is because your telecom provider is compressing the images before they are downloaded on to your phone.

There is no way to prevent this, but if you have a WiFi connection nearby, then you can turn that on. This will mean that all browser downloads come through the WiFi connection, rather than the carrier, and your images will appear normally.

If you would like to unmount your SD card for whatever reason, then drag down your notifications menu from the top of the screen and press the Settings icon.

Then go to Device management – Storage – SD card.

This will depend on your device, but you should then be able to select Unmount SD card.
