I'll add in my 2 cents since I've had my G3 for some time now. This device is incredible, and it certainly is not a 1080 screen there is a huge difference when you watch Blue-Ray 1080 movies on this screen the color, image details are flawless and perfect. Just watch 300: Rise of an Empire and you'll see what I mean. I've comparing the At&t service on my G3 with my Verizon Note 3, the G3 kills it everywhere, I have dropped calls on my Note while I get 4-5 LTE bars every here on At&t. I don't use the camera that much pictures are crisp and clean. I small hands and can manage this device one handed. My Bootanimation collection will be brought over to the G3 in full 1440×2550. I may even do some bootanimations for the circle case haven't decided yet. Anyhow, I recommend first things getting a 9H screen protector Skinobi has one for 16 dollars on Amazon, this improves screen visibility and gives it more of a greater premium look. There is Root and a modified Recovery. The recovery is good for flashing ROMs and nandroid backups, the Recovery is app based. Firmware is easy to reinstall can be done either through flashtools with the TOT firmware & dll file or via flash tools 2014 with KDZ firmware. Most likely all US models will follow the TOT & dll format. KDZ can sometimes be used for internal test updates. I should mention this as this true on International and Korean versions, not sure about models if you Root your device the system will not perform updates. This not really a concern because we can flash TOT files which provide the same update or we can flash in some cases KDZ files and have the updates well before an update is even mentioned. I'm also working on other Development efforts have a look at tapatalk Sig, to some of what I have planned. If on the fence with this device, GET IT.
