Hi. My Samsung s6 active screen is totally unresponsive. However, the volume, power and home, etc BUTTONS work. I've tried soft rebooting it (volume down + power), but touchscreen is still totally unresponsive. I've seen on other threads, there's a solution where you can enter in *#2663# on the phone, but as I said, screen is totally unresponsive. I can't even enter in my password to unlock the phone...
