Have recently Windows 8.1 runtergeschmissen from my laptop again and install Windows 7. So annoyed I had over this senseless and poorly functioning dirt. Had numerous phones, iPhones and div. Android devices, often from Samsung in the past. I was never really satisfied. iPhone must be closed, half as consistently and logically as propagated, and yes, it crashes as the other filth. Android, a Frickelei, constant hanger. And both systems: the battery. Oh man, you need a power generator so constantly doing. All unsatisfactory. So always looking for something new. Now I see Windows Phone Dual Sim, for the first time. For the price you can test. I order and I'm thrilled. The tile shit, so I thought the PC so far, really makes sense in a mobile phone, is logical, damn modern, much thoughtful as iPhone and Android. And since nothing depends, as everything runs smoothly, because nothing falls off. And then there is free off-line navigation to it. I find in the App Store less, but all I need. Yes, a few small things I would still want: flash, front camera, more quick sets. That's it. Would have been not to be expected at the price. Damn, why spend 500 euros? This is a top model. And Microsoft / Nokia are on the right track. I should buy stocks. This is again what. Now I'm waiting for high-end dual SIM: Lumia 1520 with dual SIM and 8.1. Then it's strike.
