The Phantom Digitizer Input iPad Repair Test – Only at Milliamp

We have fixed a LOT of iPads since they hit the consumer landscape, probably more than any other iPad repair company out there. From all over the world, in fact: United States, Canada, Abu Dhabi, England, and Mexico, to name but a few.

And with that exposure comes experience. Something YOU will want to have on your side when deciding who to send YOUR iPad to when you accidentally damage it (and believe me, one day, you will!).

A great example of quantity driving quality is the “phantom input” test we now perform on every iPad screen that we change out. What the hell is that?, you must be asking. Well, on just a handful of iPads that had a smashed display, they had also sustained damage to their logic board (motherboard) from the initial trauma that broke the screen.

But the interesting thing about these iPads was that the damage was not entirely evident right from the start. It wasn’t until we learned that the digitizers were acting as if the screen was being touched when they were sitting all by themselves did we realize that we had to improve our quality control testing after each iPad repair.

At first we believed the new digitizer must have failed, a bad part, and that’s why the screen was acting like a ghost was using it. But when that same screen was placed in another (never dropped or damaged) iPad, the same new digitizer worked flawlessly – no phantom inputs.

So in typical milliamp fashion, we quickly devised a simple test that every iPad that we repair must go through (and dutifully added it to our in-house device management system called millihub), wether the digitizer was repaired or not: The Phantom Digitizer Input Test.

What we do during this test is pull up this page on our website directly from the repaired iPad, and zoom in so that we can see the following image:

And then you leave the iPad alone. If the image moves off the inverted triangle (or zooms in or out), you will notice this, and if the screen detects a tap/click, you get an image that tells you that the test failed. We let currently let this test run for 30 minutes.

Note: You must change the settings temporarily on the iPad so that it does not turn off and stays on for the duration of the test.

So long, ghosts!
