Hi everyone, About 3 days ago I recived the mi4 I ordered from *******.com The first day everything was fine, the device was running smooth and perfectly. 2 days after it begun to give me problems: at first the camera didn't want to load and asked me to turn off and turn on the device and then the mi4 stopped recognizing my simcard and the wifi is always turn off. When I turn off the device it will automatically turn on by itself. the mi4 is running the 4.8.22 weekly build with android 4.4.4. I tried putting the simcard in another phone and it works. I tried looking everywhere on the net but it seems like I'm the only one in the world with this problem. I literally passed hours trying to contact the xiaomi customer service and trying to fix it. I'm really new to android world and to xiaomi world, I have no idea what to do. tl;dr : My mi4 doesn't recognize my simcard and the wifi doesen't turn on . What should I do? install an older version of the software which maybe is not bugged? How can I do it? Many many thanks. I Hope for your answer. Kind regards.
