Wesley's Tool-Box

One of the features that stand out on the iPhone 6S series is the 3D Touch. It's something you can immediately notice when you use the device for the first time because many of the stock apps take advantage of it. Basically, the phone's screen now knows how hard you push your finger against it, and translates it into triggering different functions.

In the home screen, a light touch on the app icon still launches it. But when you push it a bit harder, Quick Actions menu is triggered for the supported apps, letting you do get into various tasks even before the app is actually launched. It's something that I didn't know I wanted, but I would definitely miss it if it were gone. I'd be slightly frustrated to use older generation iPhones now thanks to this, sort of like how I feel about the lack of Touch ID on iPhone 5 and older. As it's the most obvious way that an app can be extended for 6S series, many of the 3rd party apps are now getting updated to enable this.


Here's a comparison video I made to show how 3D Touch lets you do more. On the left is an iPhone 6 Plus, and on the right is a 6S Plus. When I push the Photos app hard, 6S Plus shows the Quick Actions whereas 6 Plus only recognizes the long press and wants to know if I want to delete any apps.

Once into the app, pressing hard on a photo in 6S Plus lets me "peek", i.e. preview the photo, and if I push even harder, I "pop" into the photo and it's loaded on the screen. A light tapping feedback happens as I do this due to the Taptic Engine. On 6 Plus, nothing happens. This peek/pop interaction can be seen in many other stock apps, so I'm having fun trying to push the screen a lot to see there's anything more I can do.

Apple Watch's Korean launch is just a few days away (June 26) and I'd like to offer you a nicely consolidated list of all my reviews for your convenience. I hope this will help you get some idea on whether you should get one and how you should use it if you do.

Preview	Summary
	1. One of the first Apple Watch in Korea
	Sent three days after the official release in the US and arriving about a week later, one of the first Apple Watch to land in Korea gets prompt unboxing and gets ready for a full review.
	2. Getting the Apple Watch up & running
	I have the bands installed in place and the battery wirelessly charged up, so that I can pair the Apple Watch with my iPhone 6 Plus and make it work.
	3. Basic screens & buttons of the Apple Watch
	Apple Watch's many screens are explored, including the watch face, lock screen, home, and favourites. I also try out the digital crown and the side button.
	4. Notifications & contacts on Apple Watch
	As one of the primary functions, I took a look at how the notifications appear and interact. Then I tried contacting someone with Apple Watch, either through text or voice.
	5. Apple Watch's daily life tracking
	Fitness tracking with Apple Watch is explored, including the heartbeat measurement with an integrated sensor and the daily activity logging through a three-ring system.
	6. Running, swimming with Apple Watch
	I had both Nintendo Wii Fit Plus and Apple Watch record indoor running sessions to see how they compare. Then I went swimming with my Apple Watch to see if it'd actually work.
	7. Apple Watch as an extension, stand-in
	I tried using Apple Watch as a replacement for membership cards. Then I remote controlled my Apple TV and iPhone 6 Plus camera with it, as well.
	8. Battery life of the Apple Watch
	I recorded my Apple Watch's battery life for three weeks, through international travels and all sorts of exercises, to see if Apple's claims stood up.
	9. More Apple Watch observations
	I took a look at how fast the Apple Watch charges up and how step counting data are consolidated. Also, I have some more tips and observations on its daily use.
	10. 45 days with Apple Watch & watchOS 2
	Seven weeks later, the hardware of Apple Watch Sport is still standing up quite well. But early watchOS 2 and iOS 9 betas are incredibly rough to use.

After replacing the entire display assembly on my iPhone 6 Plus, everything seemed to be okay, except for one thing. The Touch ID sensor was not working for some reason, and it wouldn't respond to my fingerprint touches. The home button itself was working, and I could press it to go back to the home screen or call up the multitasking view.

When I went to the Settings app, Touch ID option was disabled. When I tried to re-enable it, the process immediately failed, showing the above on the screen. Also, the Reachability function that brings the screen area down half way did not work, either. This relied on lightly touching the home button quickly twice, so it must have been recognizing the fingerprint to function.


I remembered that the Touch ID cable on the display assembly's shield plate got weak while applying heat to loosen the adhesive. Thinking that maybe the connector was damaged, I ordered some replacement shield plates with the Touch ID cable on them.

Seeing that the glue can no longer cleanly fix the cracked screen, I decided to order a 3rd party replacement display assembly for my iPhone 6 Plus. Currently, they're pretty expensive - easily fetching more than US$300 with shipping cost extra - and some sellers don't really have them in stock or ask for more money once you pay the listed price. In my case, it took me three tries to get one shipped, paying about $260 for the display and $35 for shipping.

With the replacement in hand, I started disassembling the phone. After removing two pentalobe screws on the bottom and lifting the screen with a suction cup, I was able to easily disconnect the display assembly from the rest of the phone. All I needed to do was to take off the five screws holding the cable bracket, and then carefully disconnect the four cables from the display assembly.


But there were a lot of modules on the display assembly that had to be separated. They did not come with the replacement display, so they had to be re-used. And in the case of the home button, the integrated Touch ID sensor is uniquely paired with the phone and any replacement will not have the fingerprint sensing enabled due to security reasons.

So I carefully removed the earpiece speaker and the front-side camera & sensor assembly on top, and then the home button on the bottom. Where they were stuck using adhesives, I used a heat gun at a setting of 50C (122F) to loosen them.

I had been using my iPhone 6 Plus with the repaired screen for a few weeks without issues. But one day, I put the phone down on the desk a bit hard... and the screen somehow cracked like crazy even though the screen was facing up. I suppose the previous incident weakened the screen already and this was sort of a final blow.

You can see that the cracks occurred near the original hairline cracks and spread dramatically. Much of the original cracks were held together by the glue, but the nearby areas were already vulnerable to crack anyway. While the touch screen functionality was not affected, the cracks undermined the safety of my fingers and the visibility. It was time to try the Screen Glue again.
