Build 10166 on Lumia 640XL-Bugs

[Sam_93]

I installed WP10 preview build 10166. The bug I am facing is Error 0X803F8001. Another thing is momentary black screen after unlocking. Low volume. Any solution ? I have done hard reset twice .

Strange.. Hard reset should work.. It worked for me.. The black screen is a problem for all devices and cant fix it in this build..
