Any notable issue encountered for Marshmallow?

Sent from Xiaomi 2013023 using GAGT
It will come suddenly, one day. Is no symptoms onebought my g4 in may last year. havent kena anything yet haha

All the V20 seem to be marshmallow
All those who got phones back from service centre had their phones updated to V20a, then early Jan has the V20b OTA. I check now and dont see any V20c
For me on V20b now my MM issues are:
- auto brightness is messed up. In some indoor lighting it will down the brightness to absolute minimum.
- battery drain abnormally high
- SD card permission issues with MTP when plugged into PC, certain files created by 3rd party apps (like 3rd party camera app photos) cant be detected when phone contents are viewed on PC.

Better be aware of the Marshmallow issues, it could be better
not to update till it is more stable. But if you really want to
make a go for it to see what's new:
Android 6.0 Marshmallow got few bugs.

1st impression. Almost no batt drain during "standby" (airplan mode for 8hrs)Just upgraded to V20c too. Have to see if batt usage really improved as the update claims.
may i know how to upgrade to v20c?
