Stylus Pen

On models capable of using a Stylus Pen, you can find this test to evaluate them. Upon opening this test, the screen will gain 2 sets of gray squares:

The first set is the X shaped ones that cover the edges and cross the center of the screen. These you must all touch with your pen, and as you draw you should see an orange line following your pen consistently.

The second set is the larger squares near the bottom-middle of the screen. To activate these, you have to hover the pen above the screen, without touching it. You should not see an orange line appear in this case.

Pass: This test passes when all squares have been turned green.

Fail: This test fails if the timer runs out without the test having been completed. You can also manually fail this test by pressing the volume down button.
