I bought this smartphone because I wanted to change my HTC Desire HD that I had for 3 years. A colleague told me about wiko super awesome and cheap. Yes it is true cheap but it is worth no more !!! The least: Sound m ****. To hear the ringing mobile phone should have a constant headset. The people with whom one is communicating hear us from afar, must reboot the phone at least once a week. when one is wifi for a long time, it does more data reconnects. Pass in airplane mode and normal mode and code of SIM cards for the data to recovery. The most: Price / 5-inch screen / good response / SIM dual. Conclusion: Being so disappointed I bought myself a Sony Xperia Z1 after 3 months. The price is not the same but the smartphone either ...
