have the f 8 bought because it always more comes to internet, I therefore a major screen was good, ultimately offer the most now to this size or 5 inches - with more or less success. because I did not want to swim with it and underwater photography it --brauchte therefore no particular IP Group belonging - -'ve then as my old, opted for a new cynus (which also still running) - it is pleasantly light, good to handle - very quickly - recognize commands very well - has KitKat 4.4 - 2 cameras (but not the best), and dual sim - So private and business on a phone :-) battery is persistent, additional storage via SD card - So everything you need and a lot lot cheaper than others. Who does buy this smartphone can not go wrong even if the first impression from the plastic does not seem high, it is not broken, also the most use formerly a bag or protective sleeve) kind regards
