Making sure an iPhone is unlocked when buying or selling a used device can make or break the sale. It's important that the iPhone is unlocked, so that any compatible SIM card can be used. When an iPhone is locked to one cellular carrier, it cannot be used on another network. Once a device is out-of-contract carriers must unlock it when requested to do so. Many iPhones are sold unlocked, and thanks to iOS 14 there's an easy way to verify if a device is unlocked.
iOS 14's Back Tap is an accessibility feature that literally lets you tap the back of your iPhone to access system features or start shortcut automations. For example you could assign your App Switcher to the double back tap, letting you open your App Switcher simply by tapping the back of your iPhone two or three times. There are a bunch of system and accessibility features available for Back Tap, including Control Center, Home, Screenshot, Magnifier and Zoom among others, but Flashlight is noticeably missing.
Memoji on the iPhone and iPad continue to gain new options for personalization. Due to the ongoing global pandemic, Apple has added face coverings to the mix with iOS 14. Now your Memoji can sport a unique face mask to help stop the spread of COVID-19. Once a face covering is added, all of the Memoji expressions are masked automatically.
In the first major UI update since folders were introduced, iOS 14 lets you personalize your Home Screen with widgets of varying size. Obviously you can't fit every widget on your Home Screen so you have the option of adding a "Smart Stack," which is group of widgets that you can scroll through, stacked into one widget sized area. While you can remove widgets from the Smart Stack, you can't add any as it currently stands, though hopefully this will be fixed by the the time of the official release.
One of the most simple and useful apps on iPhone keeps getting better. Apple's Voice Memos has gained an audio enhancement feature with the launch of iOS 14. Much like the magic wand in Photos, with one tap the iPhone utilizes on-device processing to improve the quality of existing recordings. Enhance Recording will analyze the audio to reduce background noise and highlight important sounds, such as voices. If the results aren't to your liking, it takes one tap to undo the changes.
