Im using my asus zenfone 6 for 1 year and 3 months now and still doing great. I don't find any problem about it, only that it drains fast but its not a big deal at all for me. it jumped off my bed, table how many times but the gorilla glass is really protective. I really love usus technology.
I really like this smartphone and it work well and I did not experience any problem as people say. The battery last longer during normal use, but the battery will run out quickly when I play game as I turn off asus power optimize.
