I have a Galaxy S6, which is only 4 months old, and it will not do ANYTHING after I started the latest software update yesterday morning!! 1/2 way through the software update I lost the wi-fi signal, and 3-4 times in the past 24 hours, the home screen will pop up for approximately 10-15 seconds, but that's it! I tried to look for the software update after the shutdown and reboot started, but it states that the software update is "currently unavailable, please try again later"...then proceeded to shut down completely (again). NOT HAPPY!!!!! Will not start in "safe mode", will not stay on for more than 10-15 seconds, fully charged yet nothing happens. Any thoughts?
