I'm really liking mine so far, none of the "am I going to keep this or not" feelings I had when I got my V20. I'm not sure if that is a good or a bad thing though. I ended up loving the V20.
I'm still getting used to the smaller screen size. 5.7 on the G6 is not the same as 5.7 on the V20, but I knew that going in. The phone size is much more manageable, that's for sure. Going to give the camera a good run today. Performance appears to be quick and smooth, but haven't really put that to the test either. I did notice that apps seemed to install faster than on my V20, but they pretty much run the same.
Noticing a few issues with ffc video in some apps that is concerning, but I haven't really dug into the camera enough to tell if it's an issue or just a setting.
Overall very happy so far.
