Apple iPad Air 11-inch screen or touch input is not working correctly

The checks in more detail

If the screen reacts when you do not touch it, the cause may be moisture, a charger that adds electrical noise, or the Magic Keyboard folio pressing on the glass at the edges when closed. Try another charger and keep the Pencil away from the screen. A screen that is dead in an area or shows colored lines needs Apple, particularly after a drop. Back up in case the panel fails. Test with a second app to rule out one app. If the iPad behaves oddly only when the Magic Keyboard folio is attached, the folio's magnets and the Smart Connector can influence the screen's edge; detach it and test.

The M2 Air 11 also has a landscape front camera at the top, and a protector with a cutout that does not match can press on the sensor edge. Choose a protector made for this model, and wait a day after applying it, since fresh adhesive can leave bubbles that read as touches. Charging cables with a damaged shield can inject noise at the USB-C port, so replace a frayed cable and avoid cheap unbranded chargers. If touch faults vanish on battery and return on charge, the charger is the cause and an Apple or reputable adapter ends the problem.

On this iPad, touch trouble often comes from what is attached to it. A Magic Keyboard Folio or a case with a magnet can press against the edge of the screen, and a screen protector that was fitted with an air bubble over the edge can register phantom taps, so take the case and the protector off before testing. An Apple Pencil that is still attached to the side and charging can also confuse the screen, and detaching it for a minute is a quick test.
