It is best to avoid task killers such as Advanced Task Killer. Android is designed to automatically pre-load certain applications, even if you don’t load them yourself. If it starts to run low on memory, it will smartly unload the oldest running apps automatically.

Manually killing tasks will only mean they get loaded in memory again. Task killers can make the phone slow, laggy, or drain battery life more quickly.

The most recent version of Android now comes with a built in Flashlight / Torch App.

To find this, simply pull down to see your notifications. Then on the top bar (where you see your settings for WiFi, Bluetooth etc.), scroll across until you see Torch.

To enable or disable the vibrate function when you receive text messages go to the standard Messaging App and press More. Then Settings and then Notifications. Then select Vibrate.

If you find that a particular App is sending you too many notifications, there is a quick way to disable these.

When you receive the notification, pull down the notification screen. Then long press on the notification. You should see a small ‘i’. Press this and you should see the notifications specific to that App.

Simply select Block notifications to disable them for that App only.

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

Recent Android versions use a special mode that hides all Android related visuals. The mode is called immersive mode and it essentially means certain Apps have the whole screen available.

Sometimes this can be annoying however and you want to see the time, signal strength or batter indicator.

To temporarily leave immersive mode, simply drag down your notifications screen and the phone will exit immersive mode so you can see other features.

To set your voicemail number which allows your phone to automatically input your voicemail password, then open your Dialler App.

Then press the More or Menu button and choose Call settings. Then scroll down to Voicemail settings and set a Voicemail number (you might need to check with your carrier for the correct number).

Depending on your carrier you may have to enter the series of steps required to go through the voicemail menu, for example: *86,,yourpassword# (a comma inserts a pause).

Android has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Personal – Lock screen and security – Screen lock type – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.

This may not be available on all devices.

Having notifications come through on the lock screen can be handy because you don’t have to unlock your phone to see what the notification is about.

The problem with this is that someone may see the content of a notification (a text message for example) which you would like to keep private.

To change this setting to only display that the notification has arrive (rather than the actual content), then go to Settings – Sounds and notifications. Then under the Notifications section, select Notifications on lock screen. Select Hide content to only show the notification and not the content itself.

By default, your phone will recognise swear words, but insert x’s instead of the word. To change this, go to Settings – System – Language and input – Voice input.

Then you may need to select your voice input system. Then toggle the Block offensive words option.
