1/ Use Markup on photos — Launch Photos, open a picture, and click the three-slider icon that opens up the editing options. From there, click the three-dot icon in a circle and choose ‘Markup’.
2/ Now you can use your iPhone as a magnifying glass — To enable the magnifying lens feature in iOS 10, go to
Settings>General>Accessibility>Magnifier on your iPhone. Once it’s enabled, you triple-click your Home button to turn the rear-facing camera into a magnifying lens. In magnify mode you can zoom in and apply filters to make the little things you need to see easier to pick out. When you’re done, tape the Home button again. This isn’t the same as using the Zoom feature in Apple’s camera app; it’s more like a macro shot. It’s handy for reading small type (like that tiny grey type on Apple’s power units, chargers etc) or for seeing fine details, and it saves you from having to carry a magnifying lens around.
3/ Change Haptic Feedback — iPhone 6s and 6s Plus, and 7 and 7 Plus, have ‘haptic feedback’ Home buttons that give your finger vibration feedback. There are three levels of haptic feedback you can set to your preference, and they’re labelled 1, 2, and 3: 1 is light feedback and level 3 is the maximum. To change your level of feedback, go to Settings>General and look for Home Button, and you are presented with the same interface you get during the setup process, as shown below. You can bounce through all three settings and try them by pressing the Home Button itself. Once you’re satisfied, tap Done.
4/ Find my iPhone — OK, this one’s for everyone, whether you have upgraded to iOS 10 yet or not. Find My iPhone is a default app included with iOS and it can be used for much more than simply finding a lost iPhone (although that, of course, is a terrific feature so make sure you turn in on in Settings>iCloud).
You can log onto Find My iPhone from another iOS device signed into your Apple ID or with any web browser by going to www.icloud.com. After launching the app or clicking on Find My iPhone on the iCloud website, you’ll be asked to log in with your Apple ID email address and password (this is the same combo as for iTunes and the App Stores). If you have two-step authentication enabled for your Apple ID you will be asked to enter the secondary passcode.
After logging into Find My iPhone, a map with all the devices used with that Apple ID is displayed. Devices owned by other people on a family plan will be displayed on the map as well. If a device has been located, it’s indicated by a green circle that can be clicked for details. There’s also a dropdown menu for seeing all of the devices associated with the Apple ID account.
Click or tap on the device you want to find and Find My iPhone zooms in on its location on a map. You then have a choice to play a sound, go into Lost Mode, or totally erase the device. With such powerful options, it’s important that you guard access to Find My iPhone quite well. Two-step authentication really helps with this.
Play Sound does exactly what it says: if you have misplaced your iPhone, Play Sound will make the iPhone emit a loud sonar-type sound for five minutes. The device makes this sound even if the side mute switch is on.
5/ Lost Mode and Erase — This setting, which you can turn on in your browser as above, locks your device with a passcode, displays a custom message on the home screen including a phone number to call, and begins tracking the location of the device even if location services were originally disabled.
If the phone is off when you go into Find My iPhone, there is a checkbox to provide you with a notification when it is turned on and located. The passcode you entered remotely and the “call me” message go into effect when the device is turned on.
Erase Phone does exactly what it says. When you select Erase Phone, you have to enter the Apple ID of the device. You will receive an email confirmation if the device is on. If the device is off, the erase begins as soon as it is powered back on. Therefore, any thieves are denied access to any websites you have been to (ie, bank sites) or banking apps and other personal info like your contacts and email accounts, Facebook Messenger etc.
If the device is running iOS 7 or later, the message and phone number remain on the screen even after the phone is erased. That should increase the chances of someone returning your phone to you.
