Considering we're all pretty much glued to our phones from morning to night - it's pretty remarkable that there are still some secrets about our beloved devices we're yet to know about.
Well, get ready for you mind to be blown as one tech engineer has completely stunned the internet with an amazing hidden iPhone feature.
Abi Bouhmaida, who goes by the handle @forgoodcode, has since taken to Instagram to share with his 1.6 million followers exactly why one particular function of your phone is the 'most powerful app in the world'.
Abi has shared a life-changing hack to do with Apple's Notes app.

In the Instagram video caption he revealed: "Notes might just be the best free note-taking app you can use, provided you have an iPhone or a Mac (ideally both).
"The app is packed full of features that many note-taking apps charge money for, so if you’re not yet using it you might want to give it a shot."
The tech expert went on to tease the number one hack 'you might not know about'.
Abi explained that any iPhone users can use the Notes app - previously utilised for shopping lists or drunken ramblings - to scan documents and save them as PDFs directly onto their phone.

He then provided a fool-proof step-by-step demonstration to spread the news about the 'most powerful' feature.
To scan documents, Abi teaches, simply open the Notes app and select a note or create a new one.
Tap the Camera button on the bottom left-hand side of the screen then select 'Scan Documents' from the drop-down menu.

Your screen will then take you to your Camera with an instruction to: "Position the document in view."
Once you're happy with the placement, your document will automatically scan if your device is in Auto mode.
If it is not, you can toggle it on at the top right-hand side of the screen.
And, if your phone is in Manual mode then simply tap the Shutter button.

Then, just drag the corner to adjust the scan to properly fit the page then tap 'Keep Scan'.
All that's left is to either 'Save' the scanned doc or - if you're feeling jazzy - continue to add even more scans.
The world is quite literally your oyster.
Among the other hacks Abi explained were the ability to copy and paste text from a physical document into your Notes app; share and sync your notes with friends and family; organise your notes into folders; and create password-protected notes.

The post has since gone viral after clocking up more than 718k likes with an avalanche of comments from people eager to share their reactions.
One Instagram user exclaimed: "WOW! Mind blown - saving for reference."
"This is so helpful! I've had an iPhone for almost 10 years and I never knew any of these things," revealed a second.
A third echoed: "Thank you! I use Notes all the time! And I was just thinking the other day 'Notes is my favourite productivity app…' It rocks!"
It sure does.
