From Price => for money this is a super phone genuine. Especially three preinstalled APPS have done to me there. The APPS hot: Walk Mate, Figure Running and miCoach. These three apps are good for joggers / suitable -in. Especially the miCoach I'll probably use. The technical data I need not specially again capture (Can you yes on Amazon read). What I really like that this phone is fully dust- and waterproof. Finally you can go jogging with the phone have also in the pouring rain. With a splash-proof mobile I would not do such a thing. It's just not as powerful as Sony Xperia Z1. This mobile phone is just too big for the jog. (5 inch phone). The 3.5 inch cell phone is equipped with a dual-core processor (2x 1.0 gigahertz). Ranging from completely for this phone. For a jogger / -in, but a 3-inch cell phone would be optimal. This can be also without jogging bag (worn on left or right arm) use. I bought a Sony Ericsson Xperia Mini also the media market. Much better suited for a jog on the size. However, it is not waterproof. Pity that the market for a 3-inch cell phone is no longer there. I would hope that Sony is launching a new 3-inch cell phone on the market that the current standards. (Inclusive Dust and waterproof). Unfortunately, that probably will not happen. Unfortunately Sony. Furthermore, I have made mistakes in my Mini ONE. I installed the Android 4.1. This mobile phone has now become very slow. That's why I'm doing on the GO Mobile this Android Version 4.1 NOT draufspielen. Because of this error, I've learned from it. Thank you that your Sony provides a current Android update available for any mobile phone. Unfortunately, this is not all mobile phone manufacturers of the case.
