I bought the phone because I care a quite active lifestyle and am instructed that the phone that I carry with me, works correctly in all situations. And it does conditionally. If the display is dirty with fat fingers strengthens, it begins to spin around a bit, but mostly it helps that display times to wipe clean properly, seldom a reboot is necessary. The reception quality (the most important in the great outdoors to get medical help quickly) is Sony Typical exzelent. Where the like other phones from Samsung, HTC already are at the end, can at least still a distress signal via SMS to settle. As for the outdoor skills seems Sony not to have exaggerated. At least there has never been on the water contact problems (which I've never tested the Maxim Alerte) and dust penetrates maximum first of the two existing cases by. The only drawback: for a device of this kind I would have liked a longer lasting battery. After no more than two days is final, better one invites it daily. Customised considering the small screen size (suitable for surfing the Internet only as a stopgap in between - it has more for me not) is already very meager. Fortunately, replacement batteries are to have for little money and I would each owner of such mobiles advise you to create a spare battery in. I would buy the smartphone definitely be back, for me and my needs, it is ideal.
