I am baffled by the representation that this task requires 1-2 hours. I’ve spent at least 16 hours so far, and I’ve just gotten to the point of applying the adhesive around the perimeter of the case. I’ve done DIY with many gadgets, with cars, electricity, plumbing, painting, carpentry, masonry, and so forth, so it’s not a matter of inexperience, incompetence, or my having ten thumbs. While I am being very deliberate in this work, since this is the first time I’ve opened up a smartphone, and even tiny errors can seriously damage the phone, that doesn’t begin to account for the enormous discrepancy regarding the time this takes. Are other commenters being boastful, afraid to admit how long this is taking them, or what?
