Once you have those, go to Settings – Connections – Mobile networks – Access Point Names.
From here press the Plus sign at the top right and select New APN. Then fill in the details your carrier gave you. Then press the menu button and press Save.
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).
To copy files between your phone and PC, go to the Android Play Market and download an app called Air Droid.
This is an extremely useful App that connects your phone to your PC wirelessly, allowing you to move files and many, many other things.
Alternatively if you just want to copy using USB then simply plug a micro USB cable into your phone and it should appear as another drive on your PC.
Some phones do not allow data transfer to PC, to enable this feature go to Settings – Developer Options – Networking, and then tap on USB configuration and change it from ‘Charging’ to ‘MTP’.
Note: Developer Options is not always enabled by default. To enable, go to Settings – System – About Device. Then tap on Build number 7 times to enable this secret option.
If you prefer a different voice when listening to the Google Maps voice navigation, you can select another language or accent.
To change this, go to Settings. Then select System – Language and input – Text-to-speech options. Then under the Preferred text-to-speech engine, press the gear icon.
From there, select Language and you will be able to choose from different languages or language variations.
Looking for a charger for your Lg K40? 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.

Android manages your applications so if the phone is running low on memory, it will close the oldest running App.

Then choose the application you want to stop and select Force Stop.
To share or upload a video to services like Facebook or YouTube, simply go to your Video App and long press on a video.
Then select Share via. From here you will be given options to share the video with various services.
A great new feature is dual shot which lets you take a picture of someone else with the rear camera, while simultaneously taking a picture of yourself with the front facing camera. The problem is this feature isn’t obvious to find as it isn’t included in the list of camera Modes.
To find it open your Camera App and you will see three icons in the top right corner. Dual shot is the middle icon of these. Press that and you both cameras will activate allowing you to shoot away.
