Hello! I've just got a new BV6000 and it has BV6000_Blackview_V01_20161011 firmware installed.
I can't get OTA update to Android 7 (it says "your system is up to date"). I have two questions:

1. Are there many noticeable bugs in the latest version of firmware (20170708)? Or I'd better wait for more updates and get a more bugless version?
2. Will I ever be able to get OTA update to Android 7 or I anyway have to install one of firmware updates from the forum manually?

Thank you.

1) 20170708 seems to be a very stable version. Maybe you have to make a factory reset after update.
2) If you received not updated until today I suggest to update manually.
