I am typing this review from my new digitizer and screen!
My Samsung J3 digitizer was broken (the screen was not).
The way the digitizer was damaged, it made removal very hard as it stuck to the housing and cracked and crumbled further into shards on the bottom half (tge area opposite where the battery is housed) when I tried to remove it. In some cases I could remove the copper colored adhesive and remove parts of the digitizer. In the central areas tge digitizer left behind a black substance on top of the adhesive. Because of the nature of the damage and removal of the old digitizer it made the replacement take over an hour. After everything was removed, including the adhesive residue in some areas, the installation of the new digitizer was a breeze. Thanks!
