A manual (video) to change the glass can be found on the Internet. However, as the adhesive film is used properly and for which the other adhesive fragments are needed can only guess. At the first attempt I have the adhesive film laid over the whole area and put the display together. Then I discovered that the glue is really just the tiny thin black border and not all black film. So everything apart again and tried rauszubekommen the superfluous black film. This was of course not to destroy without the actual adhesive. After that I just put the glass so without the Blode foil top, somewhere Klebereste were still the all stick together now. My phone now looks indeed like shit but it does at least still. The delivered glass was impeccable and also the surgeon cutlery you could really use. Packt ne description purely wofúr which film is designed and how they are used then there also 5 star.
