Android 4.2 (Jellybean) Tips and Tricks

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. Go to Settings – Security – Screen lock. Then choose Face Unlock.

Once that is done go to Settings – Security – Improve face matching. 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.

Note: this may not work on all phones. Check for a software update if it doesn’t work on yours.

Normally you don’t have the ability to create shortcuts to files or folders on your home screen.

There is a workaround however. Go to the Play Store and download an App called Linda File Manager.

Once installed, browse to a file or folder. Then press and hold on the file and select Create shortcut.

The shortcut will be created on your homescreen where you can hold and drag it elsewhere if you want.

Go to Settings – Display. Then tick the Display battery percentage checkbox. If your phone doesn’t have this option, then go to the Google Play store and download a useful App called Battery Percentage.

There are two different Apps under that name, but they are both good.

There are two ways to bring up Bookmarks while browsing:

1) The quickest way is to simple long press the Back key to bring up your bookmarks

2) Alternatively you can enable the Quick Control panel. Go to Settings – Labs. Then check the option for Full screen. Then when you are browsing slide your finger in from the left or right of the screen. A semi-circular Quick Control panel will appear. Slide your finger to the top icon to see your bookmarks. This also means your browser runs in full screen mode so you maximise your website viewing area.

If you want to remove an entire text message conversation (or thread), go into Messages and look for the thread. Then long press on it and select the Trash icon.

You can also select multiple threads. Before you press the Trash, you can highlight the threads you want deleted. Then press Trash.

If you don’t want the Tab bar at the top of the browser, then you can remove this which will use the whole screen while browsing.

Open the standard browser and press Menu – Settings – Labs. Then put a check mark under Quick controls.

To get access to the controls that are now invisible, there is now a neat hidden menu. Position your finger on the right side of your phone, just off the screen. Then slide it onto the screen in a left-ward direction. A circular menu will appear with various options.

To take a screen shot, hold down the Volume Down and Power Buttons together. This will save the current screen to your phone’s memory card.

Rather than having to locate the hang up icon on the screen after each call, you can quickly end a call by pressing the Power button.

To enable this, go to Settings – Accessibility – Power button ends call.

Open your music and play a song. Then press Menu – Sound Effects. You will then be presented with an equalizer including presets.

If you want to conserve battery life, you can turn off the WiFi while the phone is asleep.

Go to Settings – WiFi – Advanced – Keep WiFi on during sleep.
