Update: It appears that a number of HTC One owners who have already received this update it appears to enhance the functionality of the capacitive buttons, which seems to be welcome news all around.
Admittedly we don’t know a lot as this software update is out of the blue, but it does bring the HTC One up to version 1.27.531.8 on Android 4.1.2. According to a few people who have already found the OTA update waiting on their devices this morning, the update includes unknown “system enhancements.” What that means exactly we don’t know, but I’d love to hear about any changes HTC One owners notice as this update arrives. Stay tuned for more info.
