Since the latest update it is running fine, with the only exception being the white balance on time lapse mode of photo every 0.5 and 1 sec. Holds charge, got just over an hour run time on 2.7k 30fps wifi on. I was sceptical but took the plunge, (usually I am the one who always gets the dud product) but am very happy with the camera. 1080p 60fs is incredible. Have not had a problem with freezing, battery, it does get a little hot of running constant 1hr, but cools down quick also.
If it helps the update process was a pain in the ass. Flash didn't work properly so had to do the manual way, but once I figured it out all was good. :)
