Although Sony Ericsson perceived the Xperia arc as a big step forward, it was little more than a refresh of the
Xperia X10. Despite this, there were some noticeable improvements in the Xperia arc. It had a far slicker design than the original Xperia X10 and was exceptionally thin at just 8.7 mm at its narrowest point.
The phone also reflected the synergies between Sony and Sony Ericsson in several areas. It included a Sony Exmor R mobile imaging sensor in its 8.1-megapixel camera, which was highly optimised for low-light conditions. It also had a 4.2-inch 480 x 854 display that used Sony's Bravia Reality Display technology.
The phone was the winner of the EISA award was winner of the EISA (European Imaging and Sound Association) award for European Camera Phone 2011-2012. It was also awarded a prestigious red dot Product Design Award in 2011.
A further nice touch was that when the Xperia Arc was connected to a Sony Bravia TV, it used the Bravia Link protocol to let users control the phone with a standard Sony TV remote and flick through content such as photographs. This was a clever value-added capability for Sony TV owners, but it was not considered to be enough to lure consumers away from rival smartphones.
The Xperia Arc was also known as the Anzu, X12 and LT15i.
