Bright/No lighting on android

I only get some lightmaps to show up om device (Marshall London running Android 5.0.2). Example:

I have all lights on stationary, Mobile HDR ticked, I have read a bunch of threads but I dont understand why only some lightmaps show up? everything share the same master material, and it cant be the number of material IDs either because the floor have some shadowing (packing 3 material IDs).
What can cause this kind of look?

Allright, so I have worked out that what I was seeing is all the quality options set to low, and I can see the same thing if I recompile shaders through Settings>Prewiev Rendering Level> Android
But why so bright? post processing has stopped to work, I can ofcourse color tint everything back into its former glory but it feels like the wrong way.

Like where are the quality setting for this mode? the normal setting change verry litle :confused:
