I have a Samsung Galaxy 6 Edge phone and twice now, the phone has gotten into a locked state, but the screen swipe does not work, it does not respond to finger swipe to unlock the device. I can push power button to get screen on or off, but no screen finger action has any effect. I cannot get it to reboot. Pushing power off button for a while brings up screen with choice to reboot, but that requires touching screen to select reboot.
I pressed power and volume down keys for several seconds to force restart, and chose normal boot from the menu, but after rebooting the issue remains, no screen swipe response. Booting into safe-mode didn't help either. I did a factory reset and still no response to screen touch. Is this a hardware issue and I need a new phone? Should I use ADB and redownload the operating system onto it?
