For those of you that came from the G3, can you give a few contrast points between the G3 and Z2? Thanks. I keep going back and forth.
Here are my thoughts after a day of use with the phone, granted this is too short of a time to really pass a final judgment.
Build quality on this phone is second to none. I own an HTC One M8 as well, and I would argue that the Z2 actually looks and feels more premium than that phone does. It feels nice in the hand despite being more or less a rectangle. There's a slight curving around the side that makes it pretty comfortable to hold, even though it is a larger device. I thought the ports being covered would bother me, but so far it hasn't been an issue since the waterproofing is such a cool feature. I took my phone in the shower with me yesterday to listen to podcasts, something I wouldn't have dreamed of doing with the other phones I've owned.
I'm not a huge fan of the software Sony has on here. I played around with the UI for all of 10 minutes before switching to Nova. It just wasn't for me. One thing I will say is that there is NO lag on this device at all. Coming from the G3 which stuttered when entering the app drawer, this is a revelation haha.
I've taken a few test shots with the camera and they have come out pretty well. Jury is still out on that though.
Screen is beautiful, not quite as nice as the M8, but certainly acceptable for the use I have for it.
Speakers could be much better, the sound is not nearly as loud as other phones I have used. The G3 was definitely louder, and so is the M8 (obviously with boomsound). I understand that this is likely a tradeoff for waterproofing the phone.
Can't really comment on battery, but it got me through a full day of fairly heavy usage yesterday. Will keep an eye on how it continues to perform.
Let me know if you have any other questions you'd like answered.
