Review Sony Xperia Z Ultra Smartphone


Ultra-huge. 6.4-inches, Full HD resolution and a Qualcomm Snapdragon 800. These are the impressive specs for the combination of a smartphone and a tablet. We are not concerned that the Xperia Ultra Z is not powerful enough to handle all upcoming tasks...

High performance; Bright display; Thickness of the device; Build quality; Port variety; Expandable storage

Price; Operation with one hand can be difficult; Black value is too high; Non-removable battery

The huge display is perfect for multimedia applications and web browsing.

Sony Xperia Z Ultra Review


The ever blurring line between smartphones and tablets just got thinner when Sony introduced the Xperia Z Ultra. At 6.4-inches, it's the largest handset to hit the Indian market and just so happens to be the most expensive. While bigger is not always...

Media The Walkman music player is very similar to the ones we’ve seen in the past and so is the video player. Audio quality is good through headphones, but the speaker volume is quite weak and not very loud. According to Sony, certain compromises had...

Sony Z Ultra Google Play Edition Review


The Sony Z Ultra Google Play Edition carves out a rather unique place in the Google collection of devices. Here you've got an ideal middle-place between smartphone and tablet, edging a lot more in on the tablet side of things. In this device is the...

Size Matters


Positioned somewhere between the Z and the Z Tab, the new Xperia Z Ultra is Sony's latest flagship phone. Actually, calling this thing a phone (or even a phablet) is a bit of a stretch, given its whopping 6.44-inch display. It is, after all, only...

Water and dust resistant. Spectacularly bright display with great contrast and wide viewing angles. 3050 mAh battery easily lasts all day

It’s crazy big. Odd dock connector location on the left-hand side. Like on the Xperia Z, the tempered-glass front and rear panels ­are still huge fingerprint magnets. Grainy low-light photos

Sony Xperia Z Ultra (Unlocked)


The well-built, beautiful Sony Xperia Z Ultra is the biggest, baddest Android smartphone you'll find, but at 6.4 inches, it takes things to such a ridiculous extreme that we're not even sure it actually qualifies as a phone.

Big, beautiful 1080p display. Slim, refined design. Fast Snapdragon 800 processor. Incredible battery life. Waterproof

Enormous. Really, it's too big. Average camera. No multitasking

Picking up the 6.44-inch Sony Xperia Z Ultra, I don't know whether to laugh or cry. I'm convinced that no mere mortal could wield this beast as their actual phone. At the same time, it's hard not to get sucked in by the superb 1080p display, blazing...

Sony Xperia Z Ultra review


Huge 6.4-inch screen great for games and movies, Top-notch specs make for snappy performance, Touchscreen works with a standard pencil, Premium look and feel, Impressively thin

Disappointing camera with no flash, Glass over the screen is to reflective, Poorly placed speaker doesn’t get loud enough, Awkward to hold due to size, slippery-ness, and square edges

The Sony Xperia Z Ultra leaves us with mixed feelings. Its components and performance are in line with the best phones we’ve tested so far; its screen is gorgeous and huge, making for great gaming and movie watching; it certainly looks and feels the...

Sony Xperia Z Ultra review: Thinking big


Unwieldy size for a phone, Non user-replaceable battery, No camera flash or camera shutter key, Below average loudspeaker performance (probably due to the increased water tightness), No proper video playback decoders (XviD, DivX) out of the box

Phone or tablet? One of the rivals was telling us to "feel free". If asked, Sony would probably go for a simple yes . As in, why not have both. As in we cannot quite make up our mind either. As in... hell yeah. The latter suits the Sony Xperia Z Ultra....

Sony Xperia Z Ultra review: the best phone you'll probably never buy


More InfoSony Xperia Z Ultra hands-onSony Xperia Z reviewSamsung Galaxy Mega reviewWhat we're about to describe is the same kind of

Beautiful display ; Sleek, gorgeous design ; Waterproof ; Powerful performance

Awkward to hold ; No camera flash ; Battery life is decent, but doesn't live up to expectations

The Z Ultra is a powerful phone with a great display, but your purchase decision will ultimately depend on the price and how well the phone fits in your hand.

Sony Xperia Z Ultra hands-on: First look


Sony just dropped a real bomb on the phablet market - a 6.4" monster that threatens to flatten the competition. The Sony Xperia Z Ultra the first officially announced device to be powered by Snapdragon 800 and it's also the thinnest device with a 1080p...

Sony Xperia Z Ultra and Z Ultra Google Play Edition review


If you're looking for the biggest smartphone you can get, without regard for portability and price, then you needn't look any further than the Sony Z Ultra. Available in two flavors, one with Sony's custom Xperia branding, apps, and services, and...

Great display ; Fast performance ; Water resistent design

Awkward handling ; Average battery life ; Software not optimized for large display size
