Although delivered were the windshield and two strips, but none of the shown tools (suction cup, picks, screwdrivers, chain hoists) or other aids. Instead of the depicted full-surface adhesive film only 2 small adhesive strip on the upper and lower range have been delivered. After the disc was clean in protective foil and bubble wrap wrapped, with an additional protective cardboard around it. Because of the missing pieces there are only three stars.
The exchange itself went smoothly by hand, but requires precise, clean work, appropriate tools and a little time. First, I removed the battery and SIM card and the defective screen covered with packing tape so that the pieces remain attached to it. With an adjustable hot air gun, set to 110 °, the old screen was about 80 ° warm. A higher temperature would damage the AMOLED. With a trapezoidal blade I have slightly raised the old screen on the top edge.
The display is fully bonded, the adhesive has a rubbery consistency. When peeling a lot of patience is required. It is advisable to put the parts to be detached only slightly under tension and then wait until the adhesive detaches from itself. As a tool I used an old credit card and these missed a sharp edge. With metal tools the risk of scratching is much higher.
Caution at the lower end of S3, where the controls are connected with a thin trace. These are bonded and must be replaced with appropriate care.
After the old disk was removed, I gently cleaned the screen with the credit card of adhesive residues and cleaned with isopropanol. Again, work with appropriate care so that there are no scratches.
Now the new tape be mounted. Sorry, no were there for the left and right sides, so I have to manage that divorced me.
Finally, I used the new display. It fits perfectly, and so is the service almost perfect success.
The only differences that I notice to the original state: The display acts turned off dark gray instead of black because there is now a tiny layer of air between the disk and the screen instead of the full-area bonding. And with me is to see where the wheel touches the screen appear exactly in the middle of a dark spot diameter of about 2 mm. However, this is seen only when the mobile phone.
Addendum 26.04.2014: The point is gone. This was caused by a "compatible" battery, which is slightly bulbous. With the original battery, the point does not arise.
