There's more to your smartphone than you might think: underneath its user-friendly, simple surface there are all kinds of hidden features and shortcuts you can take advantage of do more with your handset of choice.

Okay, okay - maybe your friends won't be that impressed unless you make your phone vanish into thin air. 

But these are all handy little tips you can use to get more out of your mobile, and maybe raise an eyebrow or two along the way.

1. Digitise your documents

Thanks to the increasing quality of smartphone cameras, you no longer need a scanner to get all of your paper files up into the cloud. Evernote, Google Driveand CamScanner are three of several apps that can do the job.

2. Identify songs in an instant

You can use apps such as Shazam or SoundHound to work out what you're listening to, but you don't have to: Google Now, Siri and Cortana can all respond to the voice command "what song is this?".

3. Put your contact details on your lock screen

If someone else finds your phone, will they be able to get it back to you? Put your details on the lock screen to make sure: the option is in Settings on Android, Health on iOS and on Windows Phone you'll have to edit the wallpaper.

5. Fix the Google Calendar time zone (Android and iOS)

Delve into the Google Calendar app settings and it's possible to fix the time zone (rather than have it update every time you travel somewhere). That way, you'll always know when something's happening at home.

iOS 9.2 added Mail Drop to iPhones, so when you email a large file from your phone you'll get a prompt to use it. Instead of attaching the file, Mail uploads it to iCloud, with the download link valid for 30 days.

8. Control your computer with your phone

A host of apps, from Spotify to YouTube, have some kind of remote control functionality built in. If you want overall control of your laptop or desktop, take a look at the likes of Unified Remote and Alfred.

Both Android and iOS now support the use of third-party keyboards, which can do everything from add extra emojis to apply some neural network processing power to your phone's autocorrect feature.

10. Find out where all your battery power is going

All the major smartphone OSes now have detailed readouts of which apps are using up most of your battery juice, so have a root through the Settings app to find the worst offenders and uninstall them if necessary.

11. Use aeroplane mode to speed up charging

Just like everyone else you probably want your phone to charge up as quickly as possible (even more so if you're in a rush). Put it in aeroplane mode and it will use much less battery life and thus charge more quickly.

12. Keep your kids or friends inside one app (Android)

On Android Marshmallow, go to Settings, Security and Screen pinning - when activated, you can 'pin' apps from the multitasking screen, so the app can't be left without a PIN. Handy for lending your handset to other people.

iOS doesn't have a safe mode, but you can quickly clear out the memory and speed everything up again - press and hold the power button, then when you see the "slide" message, press and hold the home button.

16. Unlock the System UI tuner (Android)

Android Marshmallow includes a hidden System UI tuner for playing around with the Quick Settings pane (Wi-Fi, Bluetooth, etc). To enable it, press and hold the cog icon at the top of Quick Settings, then find it in the Settings app.

17. Turn the keyboard into a trackpad (iOS)

If you're running iOS 9 or above on an iPad, an iPhone 6S or an iPhone 6S, press and hold two fingers on the keyboard to turn it into a makeshift trackpad. Unfortunately the feature doesn't work on older iPhones.

18. Go home with one button tap (Android)

Google Maps for Android offers a one-icon widget that instantly directs you to the address of your choosing - that means you can create a home screen shortcut that takes you home from anywhere with one finger tap.

19. Fall asleep to your music (iOS)

If you go into the Clock app on your iPhone you can set a countdown timer - easy enough - but you can then choose Stop Playing as the option from the When Timer Ends menu to shut off all your music after the allotted period.

20. Set your alarm to get louder and louder (Android)

Here's a tip for the Android Clock app: delve into the menu (three vertical dots) from the main alarms page then find the option that says Gradually increase volume. It gives you that extra impetus to get out of bed.

Sometimes you can't beat the feeling of a real physical button when taking your snaps - well, good news, because on Android, iOS and Windows Phone you can take photos using the volume buttons whilst in the Camera app.

If you need to get at a phone setting but you don't know where it is, just search for it - the Settings apps on both Android and iOS have search options at the top that you can use to look for obscure options.
