Hello,
I'm sorry for writing this here. Unfortnately the "Contac us"-Option currently don't work (邮件发送失败! ist the message I get).
I bought a BV8000 Pro 25.11.2017 on gearbest. I'm very happy with this phone. But unfortunately since two weeks the speaker is broken. It sounds like in this video: https://www.youtube.com/watch?v=PHYpo6uPvBI
Also it seems the mic has a problem. People say my voice sounds to loud and overdriven.
How are the next steps to use warranty and how works the warranty? I would be glad to get a reply to that questions.
Best regards and happy new year
