I tried my game on Samsung A5(SM-A500H) which is an older device because it’s always better to test games on older devices, however i found out that the game is very very dark, almost un-playable.
Unity Version: 2019.4.1f1 (LTS)
Pipeline: URP
Screenshots:
Settings:
Samsung A5 (SM-A500H) on the left
Graphics API: OpenGLES3 (Got this from Debug.log on the Samsung A5)
Samsung S9 on the right
I tried with and without PostProcessing, same results.
What can i do to overcome this issue?
This is old SRP + OpenGLES + Linear + Android before 9 bug: Very high contrast and saturation on android build (LWRP)
If your game don’t require linear rendering - just switch color space to “Gamma”
I’m using latest SRP with URP, in the thread you sent me; they said it’s fixed. This is URP, and I think it’s another bug.
I can’t use gamma, I’m using post processing and it’s better to use linear. 
If they said they fixed it, that doesn’t mean they ACTUALLY fix it.
Did you try to change Blit Type?

I’ll try that and get back to you.
@MelvMay Can you please help me on this.
@aleksandrk Any pointers?
Changing Android Blit Type to “Auto” in the Player settings should work.

Won’t that lower the FPS?
It might. Depends on what is stressed in your game.
This is the only way to reliably use linear color space on devices that don’t support it.

It worked!, thank you very much for the help!
Does “auto” mean that it would use “Never” on devices that support Linear?
@FadiObaji correct, “Auto” will not do a blit when it’s not required.

Was hopeful this was going to work but seems to do nothing on my Motorola e5 play running Android 8.0.0. Setting blit to Auto from Never made no difference at all.
Somewhat old, but still a problem. Have not tried the Blit yet, but noticed a strange behavior. On Android (new Google Pixel 6a - bought 7/2023 with nothing installed but our game), Game is very dark. Swiping up and sending it to the back ground and then immediately refocusing fixes this. It is now nice and bright!! Not really a fix for us developers, but hopefully can help Unity ( @aleksandrk ) and/or Google. Perhaps this adjusts the Blit mode?

I have the same issue on Nokia G60, the game is way darker on build. Color space is set to Gamma, I tried all 3 types of Blit types (Auto, Always, Never) - nothing changes. Any other things I can check?
Unity 2023.2.14f1
I find it odd that this issue does not occur on an older device (Samsung A10).
----EDIT----
For me it was turning off HDR Display Output that worked! Hope this can help other that may stumble onto this.
We had the same issue on Poco F5 Pro. The game was dark. I tried suggestions from this thread and from others. But finally I tried to reorder Color Gamut which fixed the issue.
It was:
Now I made:
I suppose Poco F5 Pro detected it supports DCI-P3 display and actually it doesn’t. But my thought may be wrong.
My environment:
Unity 2021.3.38f1
Post Processing 3.4.0
No SRP
Color Space: Linear
Blit Type: Auto
Auto Graphics API: Yes
Color Gamut: sRGB, DisplayP3
