Sony Ericsson Xperia Arc sales package
Two new features are introduced with the Xperia Arc. Mobile BRAVIA Engine on a Reality touch display and Mobile Exmor R CMOS camera sensor. Both technologies are originally coming from the mother company Sony but Mobile BRAVIA Engine are developed jointly by Sony and Sony Ericsson. Rumors are saying that Apple will have the Exmor R sensor in the upcoming iPhone 5.
Even if it is thin, the Sony Ericsson Xperia Arc is a relatively large smartphone with a large display. It ships in two colours and the exterior are made of hard plastic. Some users do not like plastic, but the weight are kept down and the durability is nothing to complain about. Too bad we got hold of a preview sample which a small production fault. The glossy frame going all around the phone is glossy and nice. But on our test unit the bottom of the frame seems be out of position. Take a look at the photo where the frame are out of line with the silver front frame.
Two of the three main mandatory Android keys has switched places compared to all older Android Xperia models. The Back key are located to the left and the Menu key to the right. Sony Ericsson has performed user test cases and most users wanted the back key on the left side of the Home key.
Sony Ericsson Xperia Arc running latest version of Android 2.3 Gingerbread is only 10.5mm thick. 8.7mm at the thinnest part
Display
Xperia Arc has a 4.2 inch Reality touch display with a 480 x 854 pixel resolution. It is the Sony Ericsson model with the largest display to this date. We spoke to Yamada Hiroshi, the Xperia Arc product manager at the Mobile World Congress in February. And according to him, the glass in front of the LCD display is fastened directly on the LCD which is one of the things that improves the viewing impression. By fastening the protective glass closer to the LCD pixels, it is possible to make a thinner display. The display size and the way the protective glass is fastened on the LCD is also the main difference between the little brother Xperia Neo and the Xperia Arc. The display is scratch-resistant with shatter proof sheet on mineral glass. After using the Arc for over a month, we have managed to get some scratches on the screen. All but one of them are hard to see without looking through a magnifying glass. Luckily, none of the scratches are visible when the screen is lit.
You might have heard about the Sony BRAVIA technology used by Sony on their TV-screens. The Xperia Arc is powered by Mobile BRAVIA Engine which are a feature developed jointly by Sony and Sony Ericsson. Rikard Skogberg, the official Sony Ericsson product blogger, told us on a direct question that the Mobile BRAVIA was a software only solution. So it seems that no special hardware is required to host the BRAVIA Engine and thus it should be easy to implement the same feature on future Android devices as well.

The Mobile BRAVIA Engine enhances photo and video image quality. It does so only in the gallery application. The BRAVIA engine does not affect other parts of the phone such as web browsing, gaming etc. The Mobile BRAVIA Engine can be switches off if you do not like the effects. Having Mobile BRAVIA Engine only available for the Gallery app tell us that this is not a OS feature, but something thats build in into the gallery app. As a result, third party gallery applications will not be able to take advantage of the Mobile BRAVIA enhancements and the 4.2 inch Reality display will be viewed just like any other display. We have compared the effect of the Mobile BRAVIA Engine by viewing images on the display and doing screen captures and believe that Mobile BRAVIA gives the most realistic impression for still images.
Switching BRAVIA on, modifies the shown image by adding contrast and boost color saturation slightly in real time. BRAVIA does not modify the source files and this a good thing because image files can be sharpened too much if it is done by the camera during the time of capture. The lighter part of images are sometime lighten too much in our opinion. Snow for example are often shown too light. Sony's official information about the BRAVIA Engine for televisions are listing 8 steps that modifies the image. We are not sure if all of these are relevant for the Mobile BRAVIA Engine as well, but it would not surprise us. The modifications are:
- Widens tone range. Expands the range of graduation between colours and shades giving a smoother image
- Enhances the contrast. Deeper blacks and subtle layers of gradation create a crisp picture with a stunning sense of depth.
- Matches the colours. Exact colour reproduction means what you see is exactly as it was filmed, with incredibly natural colours.
- Reduces colour distortion. 3D Comb filtration decreases cross-colour leakage and other distortions so you enjoy a more stable picture.
- Smoothes the motion. Prevents jagged edges and bleeding colours in fast moving sports and action sequences.
- Deepens the greens and blues. These traditionally difficult colours receive specific enhancement to brighten and deepen blue and green subjects.
- Cleans the images, strengthens the blacks

To better understand what the Mobile BRAVIA Engine does to the Xperia Arc display, please take a look at this page where this is demonstrated. We have transferred a handful of photos to the Arc which we have captured with a DSLR earlier. We then made a screen dump with and without the Bravia Engine turned on. Move the mouse over the images on the example page to see which difference the Bravia Engine does.
What the Mobile BRAVIA does to the media shown on the display is usually what the most compact cameras are doing to the image files. Sharpening and adding extra contrast and saturation will give images that extra pinch. The same trick found in Xperia Arc is also used by television manufactures to showcase TVs in stores. Most modern televisions has a demo / store mode where the above mentioned parameters are increased to the maximum. In our opinion, the extra pinch given to video and images by the Mobile BRAVIA Engine are positive. By adding these modifications in real time to the user, the image and video sources are unaffected.
The display size and quality is of course just one of Arcs key selling points. The other features being highlighted with this phone is that it is the worlds second phone model running the latest version of Android 2.3 Gingerbread. The form factor and thickness is also something that differentiates this Android smartphone from the other models and the Human Curvature design by Sony Ericsson continues with the Xperia Arc.
Photo and Video camera
The Xperia Arc is the best mobile phone camera we have tested to this date. In terms of picture sharpness and megapixel, the camera is as we would expect from a 2011 mobile phone. The Xperia Arc has a 8 megapixel (3264 x 2448 pixels) camera with auto focus, face recognition, smile detection and geotagging. Whats particularly impressive with the Xperia Arc is the low light capabilities. The combination of a f/2.4 lens and the Exmor R CMOS sensor will earn you approximately one extra exposure value. The official Sony Ericsson specifications says it has a 8.1 effective camera, but the pixel resolution of 3264 x 2448 sums up to 7.99 megapixel. We believe that the sensor is 8.1 megapixel and that the 0.1 megapixel frame are used when shooting with image stabilizer switched on. We have reason to believe that the image sensor used in the Xperia Arc is the Sony IMX105PQ with a 3288 x 2472 (8.13 megapixel) sensor. It is not the first time we have seen wrong official specifications from mobile phone manufactures. The claimed 8.7 mm thickness is at the center and thinnest part of the phone while the thickest part is approximately 10.5 mm which we would say is average for being a 2011 smartphone.
Camera handling
I am capturing close to 15.000 images yearly with a DSLR, so I know what I want, need and must have in a camera. What we have seen so far regarding the camera in mobile phones is an increase in number of megapixels. This is not what I want from my camera. I want instant shutter response, quick autofocus, exact white balance and exposure and a great handling. The Xperia Arc are very good at three of these request. The handling is one the things that should have been better. In our opinion, both the camera lens and the shutter key are located too far to the sides of the phone. The tiny shutter key is often hard to press because of its placement. And the camera lens is often covered by one of the fingers on the left hand. Access to the camera settings are done with a swipe on the display. The gallery with previously captured images are seen on a row to the right of the view finder, and these can be dragged entirely out of the way or dragged to cover the entire screen. Same thing about the settings. Most used settings are arranged in five icons in a row but by dragging the settings curtain to the right will reveal almost all camera options. Switching between video and still image recording are easily done by pushing one of the two soft keys at the bottom of the screen. Most applications in Android 2.3 can have landscape, portrait and inverted landscape orientation. Meaning that if the phone is tilted from normal portrait to the left or right, the orientation of the application will follow. Not so in the camera. It will always have the landscape orientation so that the shutter key are located on top of the phone. We also consider the camera response time to be a part of what we call camera handling. Xperia Arc autofocus time and image capture can be as fast as 1 image per second! Try that with your current mobile phone.
Xperia Arc vs Xperia X10 photo quality
Normal daylight photos are of similar quality as a Xperia X10 on Android 2.1. White balance precision by the Xperia Arc is very good. Only a handful of our 500+ the test photos had unacceptable white balance. We have shot and compared 50-60 images with the Xperia X10 and the Xperia Arc. Both phones has a 8 megapixel camera, are made by Sony Ericsson and both are running Android. The first thing we noticed was that the X10 file size was much higher than those from the Arc. In our test images, the average file size from the Xperia X10 was 2.63 MB. Photos of the same motive, captured with the Xperia Arc resulted in an average of 1.2 MB per file. The mixture of motives had graduated edges such as the sky and snow and others was with sharp contrast such as tree branches and gravel. Xperia Arcs smaller file size does indeed affect image quality. If you are looking at the images at 100% magnification you will see the JPEG artifact caused by too much compression. By compressing the files as much as the Xperia Arc does, images will loose details. Hopefully, a future firmware update will let users choose the JPEG compression level to certain extent.
Operating system modifications and special installed software by Sony Ericsson
Timescape and Mediascape as we know it from the first generation of Xperia Android models are gone. These apps are no longer a part of the modified Android operating system. Instead the Timescape has become a regular widget which the user can customize and place anywhere he pleases. Timescape is an application which connects your contacts with online sources. The sources for the Timescape widget can be one or more of Calls, Facebook, Messages and Twitter. Other Timescape plugins such as LinkedIn, Foursquare and Vznet can be downloaded from the Android Market for free. Removing the Sony Ericsson modifications from the Android OS source code and instead offering these as widgets is a tactical move from Sony Ericsson. The implementation of Timescape and Mediascape into the Android OS was the main reason why the first generation of Sony Ericsson Android models was very slow in getting new Android updates.
Android 2.3 Gingerbread now comes with five home screens. On the Xperia Arc these are customizable in many ways. Shortcuts, Widgets and Folders can be added to each of the five screens. Normal and Live wallpapers are commonly shared by all screens. Folder is a special implementation added by Sony Ericsson and it makes it possible to add new folders to one of the five screens or to the screen fixed menu bar. A folder can old up to 16 elements. Any icon located on the screen can be dragged into a folder. Icons from the home screens are moved while icons from the application menus are copied. Remembering which of the five home screens are holding that particular widget or app icon can be difficult if the screens are filled with widgets. To solve this, Sony Ericsson has made it possible to see all home screen widgets at the same time. Just pinch anywhere on the display to zoom out and see all widgets being reduced and nicely arranged.
The email application (not the gmail app) has got a small visual face-lift. It is now possible to have split-screen where email titles are listed to the left or on the top, and the preview pane shows a preview of the email. The preview pane functionality can be switch off, set to Landscape or set to Portrait and landscape. We are preferring the Landscape mode, but since it is only room for four titles at once we wish the title font could be smaller.
Battery
We experienced very low battery performance the first 7-8 charging cycles. The battery would only last for 4-5 hours before the display went completely black and the phone powered off. We went through full recharging cycles the first 10 times of usage before we finally saw the phone doing its job for 24 hours in a row with "normal" usage. Android 2.3 Gingerbread has a new battery usage page where information about which application and which feature was consuming battery power. The display is usually using most of the battery. Other things reported by the battery meter are Phone signal, Wi-Fi, Phone Awake, Screen On, Charging in addition to a list of running applications. A timeline will show percentage of power left and which app and feature was active. The Xperia arc is currently the only model using the new 1500 mAh BA750 battery.
