-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 The touch coordinates are read by shifting a value left by 3, this is incorrect and effectively causes the coordinates to be half of the correct value. Shift by 4 bits instead to report the correct value. This matches downstream examples, and has been confirmed on my device (OnePlus 7 Pro).
