Face Unlock allows you to unlock your phone by holding it up to your face. It is highly recommended to use the Improve Face Unlock feature to make the recognition faster and more accurate.

First, ensure you have Face Unlock enabled by going to Settings – My device – Lock screen – Screen lock and chose Face Unlock.

Once that is done go to Settings – My device – Lock screen – Improve facial recognition. You might have to do this a few times to improve the speed of recognition. It is also a good idea to position the phone at different angles to your head to improve the accuracy.

If you want to find your phone’s WiFi MAC address (for improved WiFi security), then go to Settings – More – About device – Status.

Then scroll down until you see WiFi MAC Address. The address should be a series of Hex numbers and letters.

WARNING: Making your volume or music louder can damage your hearing.

Most phones have their volumes limited by local laws to protect your hearing. There is a way to boost your volume however.

Go to the Play Store and download an App called Volume Booster or Volume+ FREE.

You may need to root your phone for this App to work, but read the instructions in the App’s description.

If you regularly visit a website you can add a shortcut to your homescreen which can be quite useful, rather than entering the web address each time you want to visit the site.

You can either do this to an existing Bookmark, or simply a page you’re visiting:

1) Open your Browser App. Enter the website you want to bookmark. You may need to wait for the whole page to load first. Then press the phone’s menu button (bottom left of the phone) and select Add shortcut to home.

2) Open your Browser App. Find an existing Bookmark by pressing the symbol in the top the right of the screen. Choose the Bookmark. Then press and hold and select Add shortcut to home.

Sometimes those Lock Screen widgets are great, sometimes they are a pain.

To disable them completely, go to Settings – More – Security

To enable Face Unlock, go into Settings – My device – Lock screen – Screen lock.

Then select Face unlock. From here you will be required to look at the phone via the front facing camera. It is usually better to do this during the day when the lighting is better, although the phone will guide you through the process.

Smartphones that are always connected to the internet are great, but if you have a data plan that is capped each month, then you will want to keep an eye on how much data you are downloading. Fortunately there is a built in feature to monitor this.

Go to Settings – Connections – Data usage. From here you can set a limit and set the usage cycle (e.g. a from and to date).

If you press the Menu button on this screen you will also see a number of features such as restrict background data usage (although this will prevent some Apps from working).

If you get tired of receiving sales calls or want to block a particular number, then you can set up auto call rejects on your device.

Often you will get calls from unknown numbers. Depending on how cautious or curious you are, then normally it’s good practice to ignore such calls. If you don’t want to answer, but you’d still like to know who the call is from, then you can simply Google the number and there are a number of websites which lists phone numbers with details about the company of the caller. From these sites you can easily see if the call you received is from a dodgy company or not.

Once you have establed that you want to block or reject the call in future, then open your normal Dialler App. Then go to Logs and find the number you want to block. Long press on the number and select Add to reject list.

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

To manage or manually enter numbers on your reject list, then again open your Dialler App. Press your Menu key and select Call settings. Then Call rejection. Then selet Auto reject list to see your reject number list. You can also manually add numbers from here

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 – More – 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 press Menu – Delete. Then press Select all (at the top) and then Delete again.

3) Go to Settings – Accounts and sync. Then untick Background data and 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.

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 home button. Then swipe left or right to close Apps.
