Stressing the BQ E4.5 with the same scenario does not trigger this bug in any way. This looks more and more like a Meizu MX4 specific issue.

Freeze happens around the 3rd or 4th shot of the same subject as reported in Bug #1519766. HDR shots of shaded lamp in semi-dark room (taking up 3/4 of view) trigger freeze on 4/5th shot. HDR shots of lamp on small table at distance in semi-dark room do not reliably trigger freeze. Normal shots do not trigger freeze, with or without zoom AFAIKS. Freeze comprises either the viewfinder holding the image of the attempted capture and app being no longer responsive and needing to be closed. Re-opening produces "Cannot access camera" error message screen, with access permission or some other error as cause. Reboot needed to regain camera function. Other freeze seen was a return of the viewfinder to a dark screen, and the same error message screen appearing."
