Sony Xperia U review: Fun united

 

The Xperia S has all the spotlight to itself in the NXT series, but history has taught us that Sony (and previously Sony Ericsson) can do wonders in the compact class. In two generations of minis and the Xperia ray, the Japanese have delivered packages...

Quad-band GSM /GPRS/EDGE support ; 3.5" 16M-color capacitive touchscreen of Full WVGA resolution (854 x 480 pixels) with Sony Mobile BRAVIA engine ; Android OS v2.3.7 Gingerbread, planned Android 4.0 ICS update ; Dual-core 1 GHz Cortex-A9 CPU, 512 MB...

Limited storage with no expansion options ; No Android 4.0 Ice Cream Sandwich out of box ; Some competitors are slimmer

So, Sony know what they're doing in the midrange. The Xperia U is so comfortably ahead of similarly priced smartphones that it's one of the easiest to recommend.

Sony Xperia U review: a little slice of Android that punches above its weight

 

More InfoSony Xperia P reviewSony officially debuts Xperia U at MWC 2012Sony Xperia U gets torn to pieces, FCC destroys something

Smooth performance ; Bright screen ; Comfortable to use

Limited storage space ; Old Gingerbread OS ; Some minor software quirks

While the Xperia U might appear to be the next one down from the P, better battery life and general performance make this a worthy consideration if you have an eye for a smaller phone.

Sony Xperia U review

 

The Xperia U is the final piece of Sony's NXT series puzzle. In March came the flagship Xperia S, a good device that shipped with outdated software. It's only just been updated to Android 4.0. Our...

Dense, bright display ; Snappy, agile performance ; Enduring battery life ; Great call quality

Ships with Android 2.3, not 4.0 ; Chubby design feels a little awkward ; LED lights not for everyone

You’ll have trouble finding a better device at this price point

Sony Xperia U Review

 

Sony pushed the Xperia S out of the door back in March, but the Xperia P and Xperia U have lagged behind a little in making it to market. Both of those devices are finally with us, and just like HTC , Sony seems to be banking on three phones hitting...

The Xperia U is decent, but we can’t look past the two glaring issues. The first is the screen: maybe we’re nitpicking, but we wouldn’t be able to live with it for an extended period of time without becoming extremely irritated. Secondly, the omission...

Sony Xperia U Review

 

The Sony Xperia U begs to be noticed with its removable bottom caps in different colors and boxy design, clearly aiming for the younger crowd, but its capable hardware and affordable price actually make it suitable for everybody. We have a dual-core...

Very good specs and design for the price ; Two seconds sleep-to-snap camera mode ; Good call quality ; Strong and clear loudspeaker ; Transparent strip illuminates with different colors

Subpar video quality ; No microSD slot ; Lack of oleophobic coating

Sony has cut a few corners to achieve the very affordable price of the Xperia U, like the lack of oleophobic coating and microSD slot, but these are still overshadowed by the cool design and the contemporary specs like a dual-core processor and screen...

An Android smartphone doesn't need to have the fastest processor, the largest touchscreen display, or the fastest mobile data speeds in order to be great. It just has to offer the right combination of hardware and software features at a price that...

Sony Xperia U: a tiny kaleidoscope with personality

 

Are you the type of person who walks down the street, head down, sliding your nondescript phone out of your pocket as you go, trying not to draw attention

Sony Xperia U - Funky Xperia

 

The smallest among the Xperia NXT family, the Sony Xperia U comes with a 3.5-inch Realty Display and a more affordable price tag. Its transparent band has some interesting tricks up its sleeve too. What are they? Read on to find out more of this handy...

Sony design imprint ; Solid build quality

No memory card slot ; Limited internal memory ; Battery life could be better ; Runs on Android 2.3

Retailing at S$488 without line contract (inclusive of GST), the Sony Xperia U is a mid-tier Android smartphone that offers an overall decent performance. While it has nothing really unique to boast about, its color-changing transparent strip and...
