I waited long and got the answer from AE Smartphone Center that sold me the BV6000:
Dear friend
We only fix it in the first 3 month
Then we only fix the software in one year
And we do not fix man made damage
But u can send us a video to YouTobe and share us the link.
https://www.youtube.com/We can help u to find the problem of the phone
If we can not help u
Hope u can find a repair store to fix it

3 months? How about ONE YEAR WARRANTY? Software repair? I get it through OTA.
Admin, can
BV help with this case?
The seller requires to BUY warranty. I civilized world one year warranty is a standard, the customer may buy extended warranty sometimes.
