If anyone has any objections, please let me know. ------------------ From: Duje Mihanović [ Upstream commit 4da515eca1b8de56c9e8a17866626f99d9bccbc7 ] The old 1.9V setting was found to be insufficient in certain environments (in my case cold ones), causing the touchscreen to register ghost touches and mostly ignore actual touches. Increase the voltage to 2.5V to correct the issue.
