[SOLVED] Texture rendering problem on Android using Unity 2017.2

Hi everyone!
I’m trying to build for an app for android (basic scrolling shooter).
When i play in the editor, the app just runs perfectly fine, even when i play it on phone through Unity Remote…
This is what i see in editor while playing:


Now, when i build the .apk and directly install it on the phone this is what i get:


I tried almost everything but really don’t know how to solve this, i built the app like a hunderd times with different settings but the problem still shows up… I think it has something to do with alpha/transparency, and it affects the darkest area of the texture somehow.
The background is just a material with a texture applied on a quad.
I’m building on a Mac and the target platform is a Galaxy Note 4.
Any help really appreciated! Thanks everyone!

UPDATE: i just disabled the POST PROCESSING BEHAVIOUR (SCRIPT) from the main camera: that was it! Unfortunately i think it’s a bug i cannot overcome at this point, but i guess it’s not an isolated case…
