When you work for Apple, even if it's not for long, you clearly become extremely familiar with the iPhone - which makes sense.
TikTok creator Tyler Morgan, who is an ex-Apple employee, has shared a whole host of quick tips and hacks that help him use his iPhone more efficiently.
The video opens with a really quick tip on using your camera app, which reminds you that you can just hold down the shutter button to start recording a video.
This can be a lot easier than swiping to the right part of the app if you're using your phone one-handed or trying to capture something on the spur of the moment. You can also slide your finger up while still holding it down to zoom in, and slide it down to zoom out - again, really useful for one-handed filming.

He also shares how to change your keyboard to be one-handed, on the same theme. When typing a message or text, if you hold down on the smiley-face emoji button at the bottom left of your display, an options menu appears.
This lets you change your keyboard language, but also has three layouts for it, which can make it smaller and send it to hug the right or left of your display, making single-handed typing simpler.
Sticking with the keyboard, Morgan shows how you can hold down the number key to type your numbers before letting go to go back to regular letters, another speedy option, while he also reminds viewers that holding down the space bar turns it into a little trackpad for selecting a part of your text to move to.
The latter is so handy for fixing typos or inserting new parts into a drafted message, as is Morgan's tip to shake your phone while typing to bring up an 'Undo' or 'Redo' option for the changes you just made.
The tips Morgan shares are very utilitarian, and they've been attracting some really fun responses as people find out things about their phones they never realised.
One comment has over 6,000 likes, and reads: "HOW DID I NOT KNOW ABOUT MOST OF THESE? I feel left out". Another viewer replied to the video: "Dude your videos are so freaking useful".
After all, for all of Apple's strengths, it does sometimes bury its descriptions of features like these deep in menus that most of us never read, so it can be hard to know they exist.
So, if you're an iPhone user looking to get a little bit more creative and technical with how you use your phone, be sure to check out Morgan's video, and the others on his page - he has plenty more little tips like these to share and help you learn.
