Hello Blackview team!
I'm very happy with your products and I think you're awesome for releasing CM12.1 for your handsets.
Nonetheless, after installing CM12.1 on my Crown, i'm encountering several issues:

- camera doesn't record video anymore, and the video resolution is always QVGA for video on the front camera.
- flip cover doesn't work anymore. When i open the cover, the screen is always black. I have to press the power button to open it.
- bluetooth speakers don't work. When connected to a bluetooth speaker, the audio always plays on the phone's speaker - even though it says it's properly connected to the speaker. Also, in Status screen, bluetooth address is Unavailable.
- GPS doesn't work. No satellites are being detected at any time. I've tried accessing engineering mode to check it, but it seems it's not included.

- Youtube application doesn't work properly. Video is sometimes black screen, and other times it just can't connect.

Anyway, thank you very much for taking the time to work on these custom roms for our devices!
We're waiting for the fixed version of the rom, as most of us really like lollipop and wouldn't want to downgrade back to 4.4.4 just because they need GPS or Bluetooth.
Best regards,
Blackview Crown XDA community.

which model ?

Could you please flash your phone to try.

Thanks for the suggestion, but that rom is the old KitKat rom. I know it worked flawlessly, but the community desires the Lollipop rom, which is still bugged.
Will those issues be fixed? Will we get a working rom for the Crown?
Thank you.

the uploaded is the latest ROM.

Hello.
I have just received my blackview crown and has the problem with draining the battery too fast.
I would say it takes around 1,5 hour to drain the battery completely.

I have updated the device using the Over the air update (wifi). I received a message
Installation successful
Upgrade success to G807_D1_H1_Blackview_V1.0_20150713

It still has the problem with the battery.

What can I do to fix it?

Well, it seems now it's much better. The only problem is the percentage being reported by the device.
It doesn't gradually drop like 100%, 99%, 98%, 97% etc.
It drops like 100%, 92%, 79% ... 19% and goes OFF. Some times it takes hours to drop from 100% to 80% and some other times it's a matter of a few minutes. Same applies to other percentages too.
I have calibrated the battery with some applications but the problem persists.
