1. Customize what Face ID unlocks

You might think face ID completely changes the passcode when it's active, but Apple actually gives a lot of control over it by unlocking face ID. For example, if you are worried about the situation described above, you can set up a Face ID so that it works for things like Apple Pay and Safari passwords, but the iPhone doesn't really unlock. Whoever wants to unlock the phone will still need a passcode.

2.Hide photos from your main Photos feed

Many of us have images in our photo feed that we don't want parents or colleagues to do when we show them our holiday pictures (or whatever). Fortunately, iOS lets you hide those photos from the main feed by keeping them in a special folder.

3.Use Reachability to reach upper-screen elements from the bottom

I love my giant iPhone XS Max, but I also admit that the options pressed on top of the display are irritating when I hold the phone with one hand. That's where accessibility facility comes in handy.

When you have an app opening up, swipe down on the digital bar at the bottom of the screen (usually white), and the top of the app will be moved halfway from the screen so you can easily press the buttons there.

4.Switch to a one-handed keyboard for easier typing on larger iPhones

Even if you have big nails, typing with one hand becomes awkward when you are trying to use one hand to type a message on the digital keyboard of the iPhone XS Max or iPhone 8 Plus. Fortunately, Apple lets you use a one-handed keyboard that is completely usable with a thumb.

5.Turn on the grid for better-framed photos

Good photography takes real skills, but you can instantly make your photos better by turning on the grid on your iPhone's camera and paying attention to some simple arrangement tips. To turn on the grid, go to settings > camera, and then toggle the grid to green. When you open your camera app again, you'll now see a fuzzy grid with nine squares.

At the most basic, this helps keep your subjects centered, but for the real artsy stuff, you should place the focus of your shot along one of the points where the lines intersect. I’m oversimplifying, but basically this is the “Rule of Thirds.If you only think of your iPhone’s Control Center as the place where you do things like adjust the volume and brightness and turn on Airplane Mode, you’re not getting the most out of it.
