My smartphone (Tablet) History: iPhone 3GS (IOS), Samsung Wave (Bada), Samsung Galaxy Note (Android 4.1), HTC One S (Android 4.0.4), Ipad (IOS) and an ASUS Nexus 7 (Android 4.2) I have that, too. So I had all operating systems except by Windows Phone. So I have in the price range around 500, I - clever made that Windows Phone is right for me. By design, my Nokia Lumia 920 and the HTC 8X have loved it right away, I can not say the Samsung Ativ S. Samsung is currently affects a little unimaginative what Desig. However, since the Nokia is much more expensive and, unfortunately, a lot heavier than the HTC, I just decided to use the 8x. The Lumia 820, which is also in this price range, never came due to the low display resolution in question. LTE is currently for me as uninteresting as the network coverage is still quite weak. Now for the HTC 8X. The design I like very much. The size and weight are perfect for me. The thickness of about 10mm falls through the rounded shape barely. On The Contrary. It feels slimmer than my HTC One S, and this is no 8mm thick. The display is first class. Very sharp and the colors are great. The speaker is also really good. For listening to music top notch during a relaxing bath. None of my other phones has this quality of sound. Via the camera and I will not say much because I very rarely or never use these. The battery is typical Smartphone to max. 1 1/5 days empty (with normal use). But that's better at any of my other phones. That is why I have made it my habit to put a long time my smartphone, no matter what I've just operating in automatically overnight to the charging cable. Now for the operating system. As mentioned at the beginning I had no phone or tablet with Windows Phone. And since I like trying out new I thought why not Winphone. 8 The homescreen with the tiles is purely visual point of view is not really mine. I think Android and IOS beautiful. But the index is still significantly better. I find everything much faster. In general, I must also say that the navigation through the menus is simple than Android. Comes very close to IOS. The operation itself is very fluid. Nothing hooked or jerky. The AppStore is obviously not (yet) as rich as in IOS or Android. What bothers me the extreme: The volume control! Why can not regulate separately for applications and phone the volume? If the ringer is on full capacity it does not mean that I want to listen to music with headphones also so loud. Or if I game in a music softly later turn the ringer back must make louder. This is really annoying! Otherwise it is cool part. The operating system is better than I thought. And 100% perfect, I find none of the 4 OS. Each has advantages and disadvantages. I'll keep all 4 have in use and to commit myself to none.
