I bought my Zenphone 6 (6z, India version) 3 weeks back. Went to long family holiday next day just after unboxing and initial setup. GPS all day, used it as my primary camera for video, photos and SloMo. Never have to use power bank.
Phone checked up every point a flagship expected to be with the massive battery and great camera.
No issue with hardware or software so far.
Little talked about dtsX with lots of headphone profile and customization, HiRes audio support with included HiRes earphone. I thought the included headphone is those shitty Nokia/Samsung one. But it's actually very good. I watched one episode of Mandalorian and blown away the sound effects.
UI is clean and simple.
Good camera, massive battery and battery management. Notice the Dual VoLTE sim. Lots of streaming and internet. 10 Hours of SOT is really good. It's like no matter if you use phone all day long, battery will keep going for 24 hours for sure.
No So good:
48mp is resolution pics are bad. Always kept at 9mp or 12mp
