Have decided on this S4, since it is the Value Edition of Galaxy S4 already the "VE". And because there is a newer device (I9515) here at Amazon again about 15 euros cheaper than the "predecessor" I9505. From previous model but you can not actually speak, because the devices are actually identical. The only noticeable difference is that the factory already have the latest version of Android 4.4.2 Kitkat's attitude and shows a new wallpaper has (which you will probably not be retained). Inside, however, the GT-i9515 is another WLAN and Bluetooth chip, the Qualcomm Atheros WCN3680 have if that's better or worse, I could not find anywhere.
About the S4 itself there are plenty of reviews (which due to the identical construction between I9505 and I9515 indeed apply to both, including again the I9505 look: Samsung Galaxy S4 smartphone (12.7 cm (4.99 inches) AMOLED touchscreen, 16 GB internal memory, 13 megapixel camera, LTE, Android 4.2) - Black), I have to add anything new, except of course I always take the cheaper and newer of two similar devices, makes sense yes.
