Replacing the previous Cyber-shot models, the K850 builds on them and although different, one can easily guess it is from the same family. The overall look is inspired by the K810 and its keypad and combines the style of the recently announced models of the manufacturer in one.

Model Dimension (Inches) Dimension (mm) Weight (oz) Weight (Gramms)
Sony Ericsson K850 4.0" x 1.90" x 0.70" 102 x 48 x 17 4.20 118
Samsung G800 4.0" x 2.0" x 0.70" 101 x 51 x 18.8 4.90 139
Nokia N95 US 3.90" x 2.10" x 0.80" 99 x 53 x 21 4.20 120
LG Viewty 4.10" x 2.10" x 0.60" 103.5 x 54.4 x 14.8 4.0 112

Similar to other new SE device, including the W880, T650 and K810, the buttons are small and with lots of space between each other which results in very precise feeling of each separate button (excellent haptic feedback). Pressing of each is also something you would like, as it is easy and one feels it clearly. Due again to the spaces between them, It is impossible to press two keys at the same time and hitting the wrong button is definitely rare.

In the pursuit of increasing the size of the display and the numeric keyboard, but not at the price of bulky dimension, some compromises had to appear. The unique thing here is the new navigation method Sony Ericsson have used – three touch sensitive buttons and 4-way d-pad built in-between the keypad. Yes, you’ve heard it right – in order to save place, the D-pad is not above the keyboard, it is over it, surrounding the “2” and “5” buttons. As the 5th (central) position, you would find on most other phones, cannot be placed here, it is exactly above, with the left and right soft buttons respectively next to it. Those three keys are pretty small and if you don’t want to touch the display, which often results in leaving of fingerprints, you must touch them with the tip of the finger. Still, they react pretty accurately and by any mean better than the ones of the Samsung phones and the LG Chocolate we’ve used. This is due to the technology, which is activated by the touch and not by electricity over your skin. Like in standard touch-sensitive display, you will find on any WM Professional device or SE UIQ phone, this buttons can be activated with stylus or any other object and not only with finger.

After the first official photos were revealed, most people were concerned about the manipulation with the D-pad, but as we’ve mentioned above, the big spaces between the numeric keys are enough for housing it. It actually has excellent relief and is very usable, more than are most others. Once you get used to the fact that the “central position” is not in the centre of the d-pad but above, you will have no concerns about it.

All keys but the top row (the touch sensitive ones) are illuminated in white (with slight purple nuance) color and when the camera is in use, the right column has additional characters backlit in blue for shortcuts to some functions. This first appeared in the K810, but it used the left column (bottom row) while the K850 now uses the right (top) one. The K770 which comes as budget version of the K850 has two rows of such shortcuts, but the K850 isn’t really jealous about this.

When (un)locking the keyboard, an impression makes the fact that the buttons illuminate from the top to the bottom row or pass out gradually (in a wave manner), which is similar to the T650’s illuminating effects. Plugging an accessory will also make the keyboard light “dance”. Unlike the T650 though, the K850 doesn’t take full advantage of this and the preloaded flash themes doesn’t interact with the backlight.

While the left side is blank, on the right there are plenty of side keys, appointed to different functions of the camera. Standard in the upper part is the volume rocker which although small feels easily, thanks to the protruding ends. It doubles as a zoom in/out in the camera, but as this is digital zoom, we will suggest you not to use it.

A characteristic which brings the K850 closer to the regular digital camera feels and operation is the camera controls constellation. The shutter key resembles the one of the T650, with projecting oval shape which makes it easy to feel. One thing that is added here is that once the camera is active, it is illuminated in blue. Strangely, it doesn’t start the camera but just focuses and acts as shutter key when pressed. To activate the camera, Sony Ericsson has put additional on/off button which is flat but still can be found easily, having in mind it is next to the shutter. This is done in order to prevent the undesired starting of the camera while using or carrying the phone but is also another likeness with camera.

On this side also is situated the 3-way switch, which will change the functionality between camera, camcorder or playback interface – just as on regular digital cameras. It moves rather hard, but when the phone is in landscape orientation it won’t really cause a problem.

The two sides and the top house a green trim, which is the same color as the D-pad. The other color version of the phone is silver instead of black and has blue trim instead of green but in both cases, the contrast is what the designers seek. We’ve also noticed it in other Sony Ericsson phones, including the Walkman Black+Orange/Gold combination which is the most obvious example. One of the S500’s color variant is even named after the contrast, called “Contrasted Copper”. This way the manufacturer tries to escape from the boring all-black or all-silver models in its own unique way.

On the front is the 2.2 inches display, which is an improvement over the 2.0” of the K800 but still lacks in size compared to the 2.6” of the N95. The resolution is the standard nowadays QVGA and the colors are 262k . Although it has slight yellowish nuance, we are happy that remains visible even in direct sunlight, which is something many displays suffered from in the past. Thanks to sensor, it is bright when it has to but saves power otherwise.

We cannot skip the fact that we are impressed by the design of the back-side. Back in the years, many manufacturers have tried to copy the look of a pocket digital camera’s face for the back of the cameraphone, but not many have succeeded. A good example is the Sony Ericsson S700, which had one of the best camera modules in a phone for its time. The K850 now repeats the success with smooth glossy black surface, central-mounted circular lens with contrasting silver border, Xenon flash with LED below it and large Cyber-shot 5.0 megapixels and Sony Ericsson labels. It looks as a feature-rich cameraphone should, but also doesn’t lack style. As the back is the “Face” of the phone while you are talking through it or using it as a camera, we think that designers should put greater effort on its look. The Sony Ericsson’s ones have done their job successfully, creating a pretty back.

The small details are the things that improve with the new generation of phones. Those who follow the history of Sony Ericsson phones must have noted that the K810 is slimmer than the K800 thanks to a redesigned lens cover. The K850 upgrades this aspect once again, with now automated lens-cover, which is inside the phone’s body and in contrast to previous models, opens easily and only when one wants to. This is logical improvement and is something we’ve seen on almost any portable digicam, but just now arrives in a cameraphone. Still, we would have preferred the cover to protect the glass in front of the lens as well because now it can be scratched.

Once again, we give our approval when it comes to changing the memory card, SIM or the battery. The back is not removable, which helps for the lack of any unwanted movement, and the bottom is opened, giving you access to what you need. This is very wily idea and we believe we will see this in future phones. Previous Sony Ericsson phones were known for the “Easy-to-put-but-hard-to-remove” sim-card slots, but the new one is totally redesigned and seems that none of the previous problems will appear here.

The K850 has some unique design details we must note. When powering the phone on, or starting the camera, if you are looking at the back, you will notice the blue circular light around the camera lens to glow. In the prototype we used a few weeks ago, the power button glowed in red when powering on, but here it is illuminated only during charging .

We’ve marked all the things that we like about the new K850, but cannot skip what we do not. Our main disrelish with the manufacturer is that it still keeps on using the proprietary connector. Even the conservative Nokia has started using 2.5/3.5mm jacks and mini/microUSB, realizing that this is what the consumer wants – standard cables and accessories which can be used with a variety of devices, no matter the brand.

The only improvement in this direction is the unique, dual-card-support. For extending the internal memory, the user can use either Sony’s M2 card (which is among all recent models of the brand) or a “standard” microSD instead of it but not both at the same time. This is a great feature as the microSD is the most popular standard now, used in most of the phones of the major brands including Nokia, Motorola, Samsung, LG, HTC, RIM and others.
