In most cases, the HTC 10 Touch Key is not broken, there just disabled and turned OFF. The reason that these keys are turned OFF is because the HTC 10 is in energy saving mode. Follow these step-by-step instructions on how to turn on the Touch Key lights on the HTC 10: Turn on the HTC 10 Open the Menu page Go to Settings Select on “Quick Settings” Select on “Power Saving” Go to “Power Saving Mode” Then go to “Restrict Performance” Uncheck the box next to “Turn off touch key light” Now the lighting of the two touch keys on the HTC 10 will be turned back on.
