Some Android widgets provide similar functionality on the GS6 edge+. For example, you add Instagram and Swarm widgets to your Galaxy's home screen, and then quickly view photos or check-in. But widgets take up valuable screen real estate, in addition to their app icons, and most are dedicated to singular purposes. The iPhone's 3D Touch gives you quick home-screen access to a variety of features within apps. The system is also new, and relatively few third-parties currently use the technology, so it has the potential to become significantly more valuable in the future.
2) iPhone 6s Plus has 'Live Photos,' Galaxy S6 edge+ doesn't
Another brand feature in the iPhone 6s and 6s Plus: "Live Photos." After you enable the feature in your Camera settings, the iPhone 6s Plus records a few seconds of audio and video before and after you snap an image, which basically amount to tiny video clips centered around your image. You view Live Photos via 3D Touch by pressing and holding a finger on pictures in your camera roll. You can use Live Photos as iPhone wallpaper, and they also "come to life" on other Apple devices.
In my experience, it's tough to purposefully capture a good Live Photo and, frankly, it's easier to capture good audio and video with the video camera. However, Live Photos are all about spontaneity, and the best way to get a good one is to simply forget about the feature, at least in my experience. My best Live Photos are the ones that capture an important detail that was lost in the still photo, such as a tiny facial movement, a quick comment from a person in the photo, or the sound of wind blowing across a river on a windy autumn day.
The GS6 edge+ camera has many bells and whistles — and a 16MP rear shooter, compared to the iPhone 6s Plus's 12MP rear camera. But it doesn't do Live Photos.
3) iPhone 6s Plus and Touch ID vs. Galaxy S6 edge+ and Samsung scanner
Fingerprint scanners are common on many of today's high-end smartphones, and both the iPhone 6s Plus and GSG edge+ have finger scanners that work well. In my experience, you rarely have to tap a finger more than once or twice to unlock or authenticate using either device.
But Apple's Touch ID is infinitely more useful than Samsung's scanner. The main purpose of such scanners is to unlock your phone, and they work seamlessly on both devices. They're also equally efficient at authenticating mobile payments, using Apple Pay, Samsung Pay and others. However, Touch ID can be used for authentication in countless other apps, while Samsung's finger scanner is limited in comparison.
