Wesley's Tool-Box

It is pretty safe to assume that the latest iPhone has the best camera in general. The tradition continues with iPhone 7, which allows me to take impressive photos like the one you see here. But to truly appreciate the improvements, a good round of comparison is in order.

First, let's look at the basic specifications as reported by the EXIF data. For the rear camera, we have these values:

And for the front camera:
Last year's rear camera was mostly about the increased pixel count; with the quality improvement taking a back seat. Front camera did jump out of the 1.2-megapixel hole, which was overdue. This year, enhancing the image quality is back in focus. The sensor can now capture on a much wider colour space (DCI-P3, a.k.a. Display-P3, instead of the traditional sRGB), and the wider aperture on the new rear lens (f/1.8, up from f/2.2) should allow for lower noise and brighter night shots. Meanwhile, the front camera can now take 7-megapixel photos.

As far as changes go, iPhone 7 is doing a big jump we've come to expect when the major number changes (e.g. iPhone 5S to iPhone 6). It just happens to be that Apple was happy to keep the general shape and size for the third generation. Personally, this seems like Apple is happy with these design decisions instead of being lazy. After all, Original iPhone style survived three generations as well until thinner design became feasible.

In any case, the packaging of the iPhone 7 is also largely the same as the previous 4.7" iPhones. Two major differences, other than the phone itself, are the photo of the iPhone on the box and the bundled EarPod earphones using the Lightning connector instead of the 3.5mm earphone jack. 3.5mm to Lightning adapter is included for those who need to use the existing earphones.


Speaking of the earphone jack, iPhone 7 indeed no longer has one as you can see here. This has been the source of much online drama, but I expect it to simmer down as time goes on, much like when Lightning connector itself was introduced with iPhone 5.

iPhones and iPads bought (or intended to be sold) in either Korea or Japan has the camera shutter sound forcibly turned on at maximum volume no matter what sound setting is used. I've noted this three years ago. This is due to local regulations, but even making a screenshot causes the same sound, which is inconvenient.

Recently, though, someone at Ruliweb has posted an interesting tip that can override this if you're using iOS 10.0.1. I would like to share this information here.

1. Run Settings app and go to General > Accessibility

2. Scroll to the bottom and enter "Accessibility Shortcut" option. Select "AssistiveTouch".

3. Back in the Accessibility menu, scroll up to the middle. Find and enter "AssistiveTouch" option.

4. Enter "Customize Top Level Menu" and remove icons until there's only one left. Select "Mute" for this icon. (If you leave two or more icons, this tip will not work.)

When you triple-click the home button, a small floating AssistiveTouch button will appear on the screen. When you press it, the system sound will be muted completely, including the camera shutter sound and alarm. Pressing the AssistiveTouch button again will re-enable the system sound, and triple-clicking the home button will hide the AssistiveTouch button.

In a nutshell, you can use AssistiveTouch to disable or enable camera shutter sound at will. User reports indicate that the tip works across all devices, including iPhone 7 that I personally confirmed. However, it doesn't seem to work on iOS 9. Therefore it isn't clear if this is a bug or an intended effect. Use at your discretion.

Ever since Apple integrated a fingerprint sensor into the iPhone's home button with 5S, unlocking the phone had been quick and painless for me. The success rate is really high, and it's basically a touch-and-go experience that is faster than even sliding to unlock. Still, Apple must have thought that this could be improved further, so now there is a 3rd generation Touch ID on my iPhone 6S Plus. How does it perform?

As the video illustrates, the speed has gotten to the point where the fingerprint recognition is virtually instantaneous. Even if my finger was resting on the home button very briefly, the lock screen would disappear. Analyzing the video, this is how long each device's Touch ID sensor took to unlock.


iPhone 6S Plus is nearly twice as fast as 6 Plus, taking only 0.23 seconds. 5S's performance was measured to be 0.70 seconds here, but it sometimes does get close to (but not surpass) 6 Plus's time of 0.40 seconds.

If 5S and 6 Plus's speed were "good enough", 6S Plus is bordering on "too fast". Unless you intentionally take your finger off the home button as quick as possible after you press or just use the power button, you'll miss the chance to see or interact with the lock screen most of the time. This includes loading the camera app via sliding up the lower right corner of the lock screen. It took a lot of time of getting used to.

Meanwhile, shooting burst photos is a completely different story.
