Product interesting at first, but it seems to have a serious battery problem. Indeed, despite a proposed "update" (must have the cable not included), the product may not load, resulting in a battery life of about one minute. In addition, the invoice screen bad, can easily after a month without doing anything, end up with lines of dead pixels.
Add to that the frequent disconnections of the product and the very poor management of SAV SonyMobile. For me after returning for "dead pixel lines" they gave me a product whose battery does not charge, and refused me exchange it after 8 months of battle.
