Very inexpensive smartphone that does not have to hide. Precise processing, back bit fiddly to remove, Micro-SIM and Micro-SD card inserted easily, battery is pre-charged, the lid on and off you go. Android 4.4.2 Kitkat runs very smoothly, very quickly, touch screen responds quickly, resolution sufficient. The neon yellow is quite strong but ok I can only recommend the Wiko Rainbow and would buy it again at any time.
