Is there such thing as a matte tempered glass screen protector for the Blackview BV6000?
I want a good tempered glass protector but I also like the matte finish for glare.

I agree that it would be great to have such a matte screen protector. I use one on my Xiaomi Redmi Note 3, and it is one of the best accessories I have ever bought, especially for using the phone outdoors.
