The Lumia 625 is a good Windows Phone 8. It scores with a strong battery life (with normal use of the 2 days), a solid camera incl. Flash, an excellent (though not as high-resolution) display, great exclusive app selection ( especially Nokia exclusive apps like Cinemagram or navigation software) and exchangeable cover. In addition, a - despite only 512MB RAM - super liquid handling and optional memory expansion through Micro-SD cards.
Where there is light, is also (some) shade. The App Store is still somewhat meager equipped (although there are now basics like Whatsapp, Instagram or Facebook) and the built-in memory is only a paltry 8 GB. I think the Lumia 625 summary for the current street price of just 200 euros a very good investment - a middle class mobile phone. OS WP8 and the previously installed software run reliably and quickly.
