Last week I updated to MIUI8, now using 8.0.2.0. After I started experiencing some problems:
- one of the SIMs is no longer recognized (should operate on 900Mhz). I tried another SIM from the same operator, same problem
- Google play keeps saying : Authentication is required. You need to sign into your Google Account. I already did it, but the next time I try to access, the same message appears
- No notifications from apps like Whatsaspp

Is the update the cause or should I look for something else?
