Looks like some of these presoldered digitizers are coming without the magnetic sensors which are located on the home button flex cable. After purchasing two of these I ended up having to harvest the OEM home button flex and moving it to the purchased digitizer. I sent a picture to the seller showing the issue. I figured I ought to put it up for your viewing as well. Note that this is showing one of the sensors near the home button. There is another sensor near the soldering joints which is a bit smaller. You can see how they work together in the youtube video above.
