It’s a difficult challenge to implement any changes to this particular phone due to its water and dust resistance. All the parts of the phone are combined and glued really tight, which makes it hard to perform a simple task such as changing the screen.
The disassembling procedure starts from the back of the phone. Firstly, we needed to heat the back panel using a heat gun and to remove it very gently with a suction cup. Once the phone is open, we needed to unplug very carefully all the flex cables from the logic board as well as small pieces such as microphones, speakers and cameras. Secondly, we had to remove the battery, which sounds easier than it actually is. Because of the water and dust resistance the battery is glued extremely strong to the bezel and there are two flex cables under it, which we can easily tear apart, but of course we shouldn’t. Having the battery pulled out makes the whole process smoother. We continued with removing the motherboard, the flex cable of the screen, the cable with the power and volume buttons and we released the final circuit board for the antenna. When all that is done, changing the actual screen was rather easy, but still it took us a bit longer time. We used the heat gun to unglue the broken screen from the frame. Then we cleaned the frame and applied new adhesive tape. The next step was to place the new screen and step by step to assemble all the parts back together. When all the parts were together, we tested thoroughly the performance of the phone before gluing the back lid.
All and all it took us three hours to finish the repair and the phone was as good as new. Our client was more than happy with result and so were we.
