I have two Diamond V97 devices. Since yesterday, the touch functionality on both devices suddenly rotated, and using the default calibration software did not resolve the issue. The display resolution is 768*1024 and now the touch resolution rotated 90 degrees clockwise!Additionally, three days ago, the firmware for both devices was updated online from version 1.1.8 to 1.1.8.2.I cannot figure out what the problem is or how to fix it!
