Hi there! I open this topic as my Xiaomi 2 has two problems : My phone isn't a fake as bought on the official website. I use the official Chinese system updated to JLB 12, Android 4.1.1. 1) Recently many people tell they can't hear me clearly. For exemple if I say: Hey where are you today? they hear: Hey ..re a.. you. .oday? It isn't always. Sometimes at the beginning of the call the person can hear and after a couple of seconds can't. Maybe my simcard has a problem, I will change it to verify. Does someone experience the same problem? 2) When I shutdown the phone, at first it closes normally. But after a couple of seconds if I press the button under the screen, I can feel the vibration as if the phone didn't completely shutdown. If I press the button on the right side of the mobile to restart it, it shows the "shutting down" screen. The progress bar is animated but stay until I take off the battery or press the right button 10 seconds to reboot. Any idea?
