Hello, I'm using the following: Xiaomi M1 MIUI 2.4.6 ICS Provider is USA T-mobile network. I have a few small problems to report which I didn't have issues with using 2.3.5 ('r' I believe). Problem #1 After receiving or making a call, my network seems to drop completely and my phone shows "No Service" for around 30 seconds before returning back with some signal. Problem #2 I seem to have difficulties in accessing my SD card using a USB cable and from the phone itself. When I select 'USB storage' mode to 'ON', the SD still fails to show on the computer. Secondly, I can't seem to use 'App 2 SD' application to move my applications such as games to the SD card; the button simply doesn't appear in the App information. Thanks for your help.
