This is a QR Code reader that can be accessed through the Control Center. Overall, the feature is similar to the reader built into the iOS camera, but with some differences. The page that is linked to the QR Code is opened directly in Safari after reading the code, without the user having to click on the link that appears on the camera.
To enable the iPhone Code Scanner, the user must access “Settings” on the cell phone, search for “Control Center” and locate the Code Scanner in the list. Afterwards, it is necessary to tap on the “+” icon, in order to be able to add to the included controls. Afterwards, just access the Control Center and press the reader icon to finish.
This option allows you to perform actions on your cell phone by touching the back of the device. In this way, it is possible to take a picture of the screen, lock the cell phone, turn on the camera, turn on the flashlight, turn down the volume, open the Notification Center and many other options. You can still enable up to two actions with this feature. Therefore, one of them will be activated when there are two taps on the back, and another when there are three consecutive taps.
To be able to activate the touch, it is necessary to go to “Settings”, click on “Accessibility”, “Touch” and scroll down to the option “Touch Behind”. After that, you can separately enable the commands. To be able to use this feature, you must have an iPhone 8 or higher, with a system from iOS 14.
The “Field Test”, in the translation into Portuguese, is an iPhone feature that allows you to see the strength of the cellular signal and other information related to the telephone network. In addition, this feature provides some technical data that can be used by network professionals to measure operator performance.
To be able to access this function, you must open the phone's dialer and enter the code *3001#12345#*. After that, press the green call button, and a panel with this technical information will immediately appear.
