From here you can choose various options.

This may not be available on all models. An alternative however is to download NoLED from the Play Store, which has many options for incoming notifications.

Looking for a charger for your Lg K4? Our guide shows you the best deals and provides advice on charger types.

Important: We take no responsibility for chargers purchased that are incompatible with your device. Please check your user manual or product descriptions before you buy.

The good news is that unless you own an iPhone (which uses the Apple Lightning Charger), almost all smartphones on the market today use the standard 5 watt Micro USB connection. This is great for consumers because it means you can normally borrow a charger from someone else if your phone is out of juice (unless they own an iPhone of course). Many shopping centres and events also provide charging stations for this connection.

Charger types
Chargers can be classified into the following four categories:

USB Charger – This is normally a simple cable that connects from your phone (micro USB port) to your laptops or desktop PCs (normal USB port). They’re super cheap and super convenient. They are often included in your phone box, but we recommend you buy extras so you can leave one at home, one at work, one at friends place etc.

Mains Charger – These also normally come in your phone’s box, but it’s also useful to have them dotted around the house or workplace so you’re never far away from a re-charge.

Car Charger – If you have a car, you should get a car charger. These simply plug into your cigarette lighter and the other end plugs into your phone. We recommend buying one for each car that you own.

Portable Charger – Also known as an external battery pack, these are great for camping, festivals or going anywhere where you may not have a mains power supply. They come in many sizes ranging from tiny portable ones providing one charge, to large power packs allowing you to charge your device multiple times.

While the stock standard keyboard is fine, there are much better keyboards available. First, you need to go to the Play Store and download one. Try searching for the word ‘keyboard’ and you will see a number of options.

One of the best keyboards is a keyboard called Swiftkey, which is a top-rate App. This will literally change the way you feel about your phone as the standard keyboard can be quite a frustrating experience.

Download your chosen keyboard and go through any install steps that you are presented with.

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.

Then, go to the App you want to type in. You should now see a little Keyboard icon on the row at the bottom of your screen, towards the bottom-right corner. Press that icon and you can switch between all of the keyboards you have installed.

To use your phone as a WiFi hotspot, tether it via USB or via Bluetooth, then go to Settings – Connections – Mobile hotspot and tethering.

You can then choose from three options:

1) USB – connect your phone via a USB cable. The phone should automatically configure the correct settings.

2) Mobile/WiFi Hotspot – To turn your phone into a WiFi hotspot, press Configure WiFi hotspot. You will then be asked to enter a Network SSID (this is your own name for the WiFi hotspot). Then choose Security and lastly, choose a password (this is password for your WiFi hotspot which you will enter on your computer).

3) Bluetooth – With this option, you will need to pair a Bluetooth device with your phone. On the other device, ensure you search for Bluetooth devices and your phone should show up.

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.

If you have forgotten your custom unlock pattern, then don’t panic.

After 5 unsuccessful tries a button should appear saying ‘Forgot pattern’. Press this and you will be asked to enter your Gmail username/password.

The phone will then ask for a new unlock pattern. If you don’t have a Gmail account, then you might have to either call your carrier or factory reset your phone.

To soft reset your phone press and hold the Power/Lock button for around 8 to 10 seconds. The phone will restart automatically.

If that doesn’t work, then remove the battery (if it has one). Wait 30 seconds and put the battery back in. Then press the Power/Lock button to turn the phone on.

Sometimes you may need your screen to stay on when plugged in via USB.

To do this, Drag down your notifications screen and press Settings. Then under System, select Developer Options. Then check Stay Awake.

If you can’t see Developer options then you need to enable this. Go to Settings – System – About device and press on Build number 7 times. Developer options will now appear in the System section of your settings.

Here are the top 5 tips to make your phone run faster:

1) Use only essential widgets on your homescreen – each widget consumes memory and processing power which can slow your down your phone.

2) Uninstall apps that you don’t use – after awhile your phone can get cluttered as some Apps are designed to always run in the background. If you rarely use an App, then uninstall it to free up memory and CPU resource.

3) Install Apps to your phone memory – if you have an SDCard, always install Apps to the phone memory, which can be accessed faster. If you have Apps on the SDCard, then move them back to the phone memory with an App called Move2SD available from the Play Market.

4) Use Static rather than Live wallpapers – Live wallpapers consume processing power and memory. Unless you really must have them, uninstall them.

5) Kill tasks occasionally – Some Apps will run in the background indefinitely unless you kill them. Most of them won’t cause a problem, but it pays to check your running tasks from time to time. Hold down your Home key and check the Task Manager.

One last thing: Don’t use Task Killers. Android manages tasks very well and Task Killers just make your phone unstable and can slow it down further.

A useful feature of Android Lollipop is what’s called Screen Pinning. This allows you to lock your phone to one App. Perfect if you have a young child that you don’t want messing with your phone. Or if you want to lend your phone to someone to make a call, but make the call only.

To enable this go to Settings – Security – Screen pinning. Then go to the App you want to Pin and press the Multitask key. Then look at the most recent app and press the blue thumb tack icon in the bottom right corner.

To un-pin an App just press the Multitask key and the back key together.
