Master your iPhone 7 At first glance on an iPhone 7 or iPhone 7 Plus , you might think that little has changed compared to the previous generation. This is obviously wrong. From the new main button that can now be customized to the new portrait mode that uses the 7 Plus dual camera, there are several new functions to discover and tame. Here is an overview of these new features, and some tips for using them. Adjust the Home button of the iPhone 7 One of the first things that is noticeable on the iPhone 7 (after noticing that it misses a headphone jack), is the fact that the home button does not move at all. Instead, there is a tactile zone in a recess that responds when pressed. The home button uses the vibrator to simulate the feel of a button . This applies to both iPhone 7 and iPhone 7 Plus with haptic Home buttons: Open “Settings” and go to “General” Choose “Home Button” to access the Home button click preferences Tap on the 1, 2, or 3, and then press the Home button to test how it feels 1 – soft and subtle feedback when Home button is pressed 2 – moderate feedback on pressing Home button 3 – strongest feedback when pressing Home button Restarting an iPhone 7 A main button that does not move anymore means that you have to go through a new method to force restart of an iPhone 7 and 7 Plus . Instead of holding the main button and the power button at the same time for a few seconds, as on the previous iPhone, you must now hold the power button and the volume buttons at the same time . It takes time to adapt, especially for long-time iPhone users, but it's a simple method to master once you know how to do it. Use the optical zoom of the iPhone 7 Plus Here is a function that the iPhone 7 Plus offers out of the box: the use of its double camera to zoom on objects. From the Camera application, tap the "1x" button at the bottom of the image to apply an optical zoom , marked with a "2x". Tap this button again to return to a 1x zoom. To get a better zoom, keep your finger on the "1x" button to make an arc appear. By sliding your finger on it, you can zoom up to 10x , but you will then use the digital zoom of the camera, which will degrade the image quality. Finally, if you are used to pinching the image to zoom in or zoom out, this function is always available in the camera, and you can also mount up to 10x, without having the same accuracy as The first method. Lock the lens of the iPhone 7 Plus Adding a second sensor and optical zoom arrives with new settings for the camera. You can now lock the lens of your camera when shooting. This will prevent the camera from switching from one sensor to another in full video, thus avoiding the slight jumps in the image that a lens change may cause. In the Settings, click Photos and Camera, and choose Record Video. You will find the option " Lock Camera Lens ". Adjust the unlocking of the iPhone with Touch ID IOS 10 changes the way you can unlock your iPhone with Touch ID, which requires pressing the main button instead of just leaving your finger. This may be a bit unusual for some users, especially for longtime iPhone users. There is, however, a way to modify it and to return to the old system, provided that one knows where to look. Going to Settings> General> Accessibility, you will find the Home Button option. In this menu, you can check the option Touch to open, which allows you to simply rest your finger on the sensor to unlock the iPhone. Find the shortcut to the camera Here is another shortcut to iOS 10 that might surprise former iPhone users who would move to an iPhone 7 or 7 Plus. In iOS 9, the locked screen offered a shortcut to the camera represented by an icon at the bottom of the screen, which allowed you to launch without having to unlock the phone. Ideal for taking a picture quickly without having to go through the main menu of the iPhone. In iOS 10, this icon has disappeared, but the option still exists and Apple has simplified its access. From the locked screen, simply slide your finger from right to left. The Camera application will launch on the iPhone and will be ready for use. Turn off automatic screen activation The function Rise to Wake, which allows your iPhone to display the screen locked when you hold it at eye level, is one of the most original iOS 10. But you may prefer to see your smartphone turn on only When you ask him. In this case, there is a menu allowing you to disable the function. This time, go to Settings and choose Display & Brightness. Here you will find an option to uncheck to disable the Rise to Wake function. Transform your keyboard into a trackpad This function is not quite new on iPhone 7 and 7 Plus, but it still represents an interesting use of the 3D Touch function.When you write a note, email or message and want to move the cursor to correct an error or choose a word, you can place your finger where you want to put it. But this method lacks precision, and it can be difficult to see exactly where the cursor is under his finger. Instead, a strong pressure on the keyboard allows to reveal another method: the keyboard disappears, and you end up with a semblance of trackpad. You can now move your cursor anywhere by sliding your finger into that space. Once the cursor hovers over the word you want, press it again to select the word. A double strong pressure will select the entire sentence. Change the resolution of the video You may not have 4K TV yet, but it could only be a matter of time. At this time, the iPhone 7 will already be able to offer videos corresponding to this resolution. Open the settings and go to Photos and Camera, and then scroll to Video Recording. It offers several recording formats in various resolutions and frame rates, between 720p at 30 frames per second and 4K. Note that the size of the video will obviously change depending on the format chosen: iOS warns you that one minute of 4K video weighs 350 MB, nearly 6 times the volume of a video at the lowest definition. Take a Live Photo The iPhone 6s had been the first to use Live Photos: still images that come alive when you press it, and that you can do with your camera, which will automatically take a short video with each shot. Live Photos is enabled by default. You can see this through the icon at the top, at the center of the screen in the Camera application. If the icon is yellow, the option is activated: tap it to disable it. When Live Photos is enabled, your iPhone will take a short 1.5 second video before and after your shooting, to animate it all afterwards. "Live" appears on the display to indicate that the camera is still recording. Edit Live Photos Now that you can take Live Photos with your iPhone 7, you can also edit them. In iOS 10, the editing tool in the Photos application allows this. Choose a photo, and tap the edit button at the bottom of the screen (which looks like three cursors one above the other). From there, you can choose the size, adjust the brightness and color, or add a filter without losing animation. Like the classic photos, the editions do not delete the original version, which you can find afterwards.
