I have a problem with my mipad 2. Every time I closed the tablet when I open it the system time is stopping in the time that I closed the tablet. I have to connect to the internet after enable the option automatic date & time to fix the time evry time. My tablet was windows version from the factory and I install the MIUI. This is happening from the first day of the purchase both in winnows and MIUI. I tried both stable and developer and EU roms and I have the same bug. I did factory reset wipes but i couldn't fix it.
