Totally love it!! After the first few problems were fixed by factory upgrades

sabbeijing has owned it for less than year before publishing this review

Bought it in 2013 August in Beijing from HK smuggled grey import.

Immidiatelly Loved the design and the size. I knew that no other company will ever try to make a bigger phone since this is just exactly fit a regular pocket of normal pants. They started to increase the size recently they will ended up at Sony Z ultra's 6.4 inch size because there is no point to make a bigger phone which won't fit to your pocket in the future.

In the very first month, I had troubles with the power switch button, the screen stayed blank after calls. Couldn't hang up! But few weeks later an update is fixed this problem. After using it for a half a year the back panel got loose (and there is no screws there) the phone started to suprise me with sudden shut downs. Lost setup details and current time set all the time. The service pushed a little of glue behind the panel and it seems to be working now. But afraid to use it without protecting case in order to keep the back panel firm and steady.

Pros: Love the text input, love the screen, love the icon setup abilities, love the off-line voice recognition, love the design, love its speed and hardware.

Negativ: battery time way too short for the fun it's provide (browsing and watching anything is like a small laptop), camera out of date quality (I bet it would have been way too expensive with a better unit) Not so firm case.

Stll the most admirable and unique phone of the market of 2013-2014!!!!

Some Great Aspects, But still lack in some departements

refillable has owned it for less than year before publishing this review

Bought in January. I would really call this phone a mini-tablet rather than a phablet. But that's probably because I wear size 8 gloves, but still, this device dwarfs the Mega 6.3.

The nice things about this phablet is snappy Performance, Great screen, Good Battery Life, MicroSD support, Premium build quality, Waterproof and Price. We would be paying $150-$200 more for a Note 3.

However, We have issues on the Ergonomics (stated before), Camera and lack of flash, speaker quality/Loudness and Call quality.

Overall, a worthy contender if you're looking for a Note 3 Alternative.

Build quality 9/10 Great Premium build quality, but can still be improved. A curved back would help a little.
Reception 9/10 Does receive signals pretty well for it's class, but surely not the best.
Call quality 7/10 Pretty Average call quality to be honest.
Internet 10/10 The snappy Snapdragon 800 SoC and the 6.4" display lets internet Browsing a breeze. I am using Dolphin Browser.
Multimedia 10/10 Great 6.4" screen and fluid operations of the device lets you have a great experience on multimedia.
Camera 6/10 This is where We're dissapointed the most. Outside, the 8MP shooter could give an OK result, does preserve details pretty well, but colours are sometimes not accurate. But indoors, the lack of flash forced us to crank up the ISO setting and have horrible noise in the pictures. Although buying an external flash could help, it will subtract your bank account at least $50.
UI speed 10/10 Blazing fast for it's class. It's SD 800 afterall.
Everyday usage 8/10 Great, but not perfect. Does do tasks very well, but the ergonomics limits it somewhat.
Text input 9/10 We have very few issues with the Z Ultra's keyboard.
Display 10/10 Gorgeous screen. Excellent for it's class.
Battery 9/10 Could be improved, but the battery can last a day on us with a moderate to heavy usage. Charging with the original adapter only takes 30 minutes at most.

Best phone I have owned yet

sconerad has owned it for less than month before publishing this review

Bought this phone at Christmas, and having come from the HTC one, it felt massive, but after about a week, I got used the the size and felt like it was an actual phone, it has amazingly nice colours and its a joy to watch movies on it, checking facebook is super nice as well as its easier to read everything. the camera isnt to bad, but it lacks detail, audio is a bit muffled as well, but im guessing thats because if the water proof or something. I have shot video under water in my pool and its pretty cool to do that with a phone. The phone feels of quality and my only negative would be that the protective sheet over the screen is hard to clean from fingerprints and oils. But awesome phone and would recommend to anyone looking for a large phone
