Sony Ericsson K770

Posted: , posted by PhoneArena Team



A mobile phone’s design plays an important role in the consumers’ purchasing decision: one would hardly ever buy a visually unappealing phone, no matter how functional it can be. Being well aware of this, manufacturers invest not only in the phones’ technical development, but also in the improvement of their design, using distinctive colors, materials, lights or other features that can make their phones stand out among the competition.

The Sony Ericsson К770 we’re reviewing is a standard candybar with dimensions of 105 x 47 x 14.5 mm (4.1 x 1.8 x 0.6 inches) and weight of 95 g (3.4 oz), which makes it an average device as far as size and weight are concerned.

Model Dimension (Inches) Dimension (mm) Weight (oz) Weight (Gramms)
Sony Ericsson K770 4.10" x 1.90" x 0.60" 105 x 47 x 14.5 3.4 95
Sony Ericsson T650 4.10" x 1.80" x 0.50" 104 x 46 x 12.5 3.4 95
Sony Ericsson K850 4.00" x 1.90" x 0.70" 102 x 48 x 17 4.2 118
Sony Ericsson K810 4.20" x 1.90" x 0.70" 106 x 48 x 17 3.60 104

The phone does not claim to be neither thin nor small, nor light: just an average phone. The device we’ve tested was of a color called Truffle Brown; you have two more options as far as color is concerned: Sandy Beige and Ultra Violet.

The 1.9-inch display has a resolution of 240 x 320 pixels (QVGA) and shows 262,144-colors. Just like in the case of Т650, the display does not take up all the space of the protective glass, leaving the fringe empty, which might put you off. The images are bright and contrasting with saturated colors and are well visible even in broad daylight. The light censor, located above the display, regulates the brightness: if it’s dark, the brightness is reduced, in bright light it’s decreased. This dynamic regulation ensures good visibility depending on the environment and so you do not have to make corrections manually. The light censor is a new feature in Sony Ericsson phones (K850 and Т650) and we would appreciate it in more models to come. Our overall impressions of the display are positive and we consider it almost on a par with the quality of the latest Nokia models (6500 series, N95, etc.).

Under the display is the navigation button, surrounded by the other keys, relevant to the phone’s navigation: the left and right soft keys, back and clear key, and internet and shortcut menu keys. These keys are located very close to one another, but they can be told apart quite easily, pressing them is easy and working with them is generally convenient.

Lower down is the numeric keyboard with considerable space between the rows and none between the columns. Its keys are long and slim, which, together with their good relief, makes them very convenient and easy to distinguish and press. On these keys, apart from the standard inscriptions (numbers and letters), you’ll also find icons, indicating their functions in camera mode. When you are working with the phone, the keys that you need are backlit in white. The buttons that are active in camera mode are backlit in blue. This is a very good solution that we saw in К810/К850, ensuring easier work with the camera without obstructing working with the rest of the phone’s functions. The idea is further developed in К770, compared to the above-mentioned models, and we have two, rather than one row of shortcuts.

The right-hand side keys - volume keys and camera key are a little more difficult to work with. During conversation you can easily find the position of the volume keys, but pressing them is difficult, so that you have to use the tip of your thumb. There is a similar inconvenience, related to the camera key: it is slim, but you have to press it a little harder to take a picture. However, when pressing hard, you can budge and so the picture will come out blurred. We think pressing the keys with your nail, rather than with the finger tip is the easiest way to do it. You’ll not find any other keys on the left-hand side, apart from the universal connector, used for charging or connecting to additional accessories (handsfree, data cable, etc.).

At the top is the on/off key, which can be used for a quick profile change, as well as for some other functions. Right next to it is the slider, which releases the back lid, so that you have access to the battery, and the SIM and memory cards that can be found just under it. The type of the additional memory is Memory Stick Micro (M2) and, since it is hot-swappable, you do not have to switch off your phone in order to replace it or put it back.

The whole back panel of the phone is taken up by the lid, which is attached solidly without any play, which speaks of the phone’s precise make and construction. The lens of the 3.2-megapixel camera are also here, covered by a sliding metal lid, fitted on the lid itself. This is a traditional solution for protecting the lens, which we have seen in other Cyber-shots models, though not so advanced as the model used for К850, where the lens open automatically. When sliding it the camera goes on and two blue lights go on at the back – those have a decorative role, rather than any other function. LED flash and the auto-picture mirror are located next to the lens and the loudspeaker is in the lower part of the lid, right next to the Sony Ericsson logo. The second camera, intended for video talks, is on the front part, right above the display to the right of the “Sony Ericsson” inscription.

The phone’s make and structure are rather good, although the materials that have been used are not as impressive same as the ones used to make Т650. The only metal part is the lid, protecting the lens and the mechanism it slides along, which, on the other hand, is the main reason for К770 to be a little thicker than Т650.
