Wesley's Tool-Box

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.

I've cracked the back side of an iPhone when it was made of glass, but never the front side. That changed with iPhone 6 Plus - the screen got hairline cracks when the device was dropped from about 50cm (1 1/2 feet) high onto a brick road. Getting an iPhone bought overseas serviced by an Apple designated service center in Korea isn't possible due to local warranty (as opposed to world-wide), so I looked for other ways to get this fixed.


This is when I found this "Screen Glue" manufactured by DiYPRO which claimed to fix screen cracks by filling the gaps with a UV-curing glue. The package, which costs about US$17, comes with 5 ml of the glue and a sheet of instructions. Frankly, the price seemed steep for the amount of glue provided, but if it could get the job done, I thought it wasn't too bad. So I bought a bottle and got to work.
