A handy feature of Android is to quickly clear your notifications.

Simply pull down your notifications bar by swiping your finger from the top of your phone downwards.

Then when you see each individual notification, swipe your finger left or right to clear each one. You can do this with your Apps too – press and hold the multitasking button. Then swipe left or right to close Apps.

If you want to access certain features of your device that are only available to developers, then you want the Developer options setting.

On most devices, this feature is hidden so you will need to pull down your notifications screen go into Settings. Then scroll down to About device.

Then you should see Build Number. This needs to be pressed a total of seven times. You should get a message at the fourth press. On the seventh, you’ll get another message saying that Developer Options are unlocked.

There is no need to be stuck with the standard Android keyboard, which isn’t always great for typing quickly.

Go to the Play Store and search for ‘Keyboard’ to see some great alternatives, many of which are more accurate and make typing much easier.

One of the very best is SwiftKey. They provide a free trial, but once the trial is over it is well worth the small amount of money they charge. It can increase your typing rates massively.

Another good one is GoKeyboard.

If you see a warning saying the keyboard will collect all information (including credit cards) just ignore this. This is just a security feature that Android shows for every third-party keyboard that you install.

Android has an interesting new feature called Talkback which is designed for blind and low vision users.

The feature is an interesting way to navigate your phone however.

Simply go to Settings – Personal – Accessibility – Talkback to activate it.

Then your phone will give you an ongoing narration of its various functions.

If you don’t like the default A-Z way of viewing your contacts you can change this.

First, go to your Contacts App and press the Menu key or More at the top of the screen. Then select Settings.

Then choose Sort by.

To adjust your screen brightness, there are two options:

1) Simply drag your finger from the top of the phone down to pull down your quick settings screen. Then at the top there will be a brightness bar. Drag this left or right or press Auto.

2) Drag your notifications screen down and select Settings. Then under Device, select Display – Brightness. Then choose the desired brightness setting.

You can also select Automatic brightness to let the phone decide for you.

Warning: This will remove ALL data on the phone (but not the MicroSD card).

To perform a hard reset, or factory reset, then there are a number of methods to try:

1) Go to Settings – Personal – Backup and reset – Factory data reset – Reset device. It may ask for a password. Then select Erase everything.

If the phone is totally unresponsive, even after a reboot, then try the following methods.

2) While the phone is turned off, press and hold the Volume Up and Volume Down buttons together. Then, while holding these, press and release the Power button (keep holding the volume buttons). The phone should turn on and a menu will appear. Press the Volume down button to navigate to the Recovery option. Press the Volume Up to select (if that doesn’t work, use the Power button to select). A yellow triangle and an Android logo will appear. Press the Volume Down and Volume Up button together and a recovery menu should appear. Use the Volume buttons to move to the Wipe data/Factory reset option and then press Power to select. Again, use the Volume Down key to choose Yes and press the Power button again to select.

3) While the phone is turned off, press and hold the Volume Down button. Then, while holding, press and release the Power button. A menu should appear. Use the Volume down key to go to Clear Storage. Use the Power button to select the option. Then when asked to confirm, press Volume Up for Yes.

4) While the phone is off, press and hold down Volume Up + Home + Power buttons at the same time. Then release the buttons when you see the Logo. Use the Volume Down button to go down and the Home or Power key to select. Choose the Wipe data/Factory reset option. Then Select Yes to delete all user data. Then choose to reboot the phone.

5) A final method is to enter the code into your phone’s dialler: *2767*3855# This method will not give you an option to reverse the process, so be careful! This method will only work if you can boot into your phone.

If you don’t want to hear the shutter sound when you take photos, then there are a few things you can try.

Firstly, some countries have laws to force the phone to play these sounds. Assuming you’re not in one of these countries, then the first thing you can try is to go to the Camera App – Settings – Shutter Sound – Off.

If that doesn’t work, then you can try turning the volume of the phone down or put it in silent mode when taking photos.

The last option is to Root your phone. If you don’t know what that means, then it’s best not to attempt it unless you have thoroughly read about the process. Once Rooted, go to this folder on your phone: /system/media/audio/ui and rename the camerashutter and/or cameraclick OGG files to something else.

Alternatively, on a rooted phone you can use a Root Browser, to edit /system/csc/feature.xml and set the option to TRUE. Then you should be able to go to Camera App – Settings – Shutter Sound – Off.
