There seems to be a problem on the mi-1 with the new MIUI transfer tool. I've successfully sent a picture from my mi-2 to my mi-1 using the tool but the mi-1 won't return to normal wifi operation after using the transfer tool. Instead, there is a portable wifi hotspot active that can't be disabled. The only way i've found to return to normal wifi operation out is to reboot the device. The problem doesn't seem to exist on the mi-2. When I send a file from the mi-1 to the mi-2 using MIUI transfer, the mi-2 returns to normal wifi operation at the completion of the transfer.
