Smartphones are at the centre of everyday reality in which they have become constant companions. Since smartphones are continuously in use, they have to be robust and easy to operate. The development of the Xperia E3 focuses particularly on reliability in use and thus on an equally high standard of user-friendliness. The aim was to combine design and quality into one product that perfectly adapts to the lifestyle of its users. Furthermore, this smartphone has emerged by taking on the OmniBalance design concept with the aim of offering balance and symmetry in all angles. The result is a device with a well-balanced appearance and a form that impresses with purist self-sufficiency. The matte finish of the frame lends it both a slim profile and a pleasant tactile feel. The phone rests comfortably in the hand, thanks to its rounded side edges that also lend it a high degree of sturdiness. The Xperia E3 can be operated with just one hand, which is of great benefit in many everyday situations, and even offers users an innovative photo app. Also outstanding are the processing speed and the high degree of durability since the soft yet robust edges ensure that it does not dent and thus keeps looking new for a longer period of time. With its slim and symmetric design it fascinates users anew every single day.
