I have a Blackview bv8000 pro with the latest current firmware, and the following bugs:
Firmware update of 14 August 2017,
But the bugs still persist:

-contrast looks to light when the phone is in very light areas, only a brightness setting would of been nicer, please fix or give us the option to deactivate this contrast change on high lighted areas, the admins sayed the new firmware will fix this, I updated by OTA, full reset, the problem still persists

- waze app just won't launch on bv8000
Tryed reinstalling it, factory reset, reinstalled, still not working

-The tactic back button, only works when you tap on the exact center of it, the home and option tactic buttons respond better when I press near them, other devices then BV8000 pro, react great when I press near the tactic buttons.(this is not a very big problem, but is annoying)

But the contrast and waze not working, is not acceptable.

Please make a functional fix for this problems.

The tactic back button, only works when you tap on the exact center of it, the home and option tactic buttons respond better when I press near them, other devices then BV8000 pro, react great when I press near the tactic buttons.(this is not a very big problem, but is annoying)

same here, the back button works only if you tap in the exact center, home and option respond super good.
How can i solve it?

Same problems here. The most unacceptable is about Waze since I use it almost every day.

Updated to 20170822, now waze works, back button still works only when pressing on center of it(not really a bad issue after all.
Contrast still changes, but looks good now!

Thank you BV for the work and fix!
