Development Rendering

Hi, guys!

I have a problems with lighting on mobile device (Sony TX, Android 4.3; other platforms isn’t tested). It’s too bright. In mobile preview all right. But on real mobile this is a hell. Look:

And real mobile device: http://pic.noptor.ru/images/A1iH9speanUulI9o2fHW.png

If I disable mobile hdr all works fine, but fog is disappears too. But I need a fog :c Can u help me?

PS: I’m use Sky Light with disabled «Lower hemisphere is black» and «Cast shadows». Source type: simple white cubemap.

Up theme.

On other device (Samsung Galaxy Tab 2) I have other bug of renderer. Look: http://pic.noptor.ru/images/s0WVuWbN3YwBZ6nGxYOc.jpg
This bug reproduced on every level from starter content too.

I’m downloaded «Epic Citadel» app for test UnrealEngine compatibility with my devices — it works fine.

What could be the problem? Where to find the cause?
