Question by Sozey · Sep 30, 2017 at 05:00 PM · androiderrorshadermobileblackscreen

Black screen on Android build

Hi everyone, I'm currently working on a mobile game and tried my project on an Android device for the first time today. The problem I ran into is that although my UI appears correctly, the rest of my scene is solid black, on both my phone and a Samsung Galaxy tablet. I only use the standard shader for now. I also tried this same build on an Android emulator for PC (Nox) and it works there without any problem. Does anyone know what could cause this and perhaps how to fix it ? Thank you in advance !

So, guys, we solved the problem just by downgrading our Unity version.

I guess you are using Unity 2017.3, so just make sure you've made a backup of all your projects and download Unity 2017.1 again.

That should work. I hope it can help you too.

It was the new post processing on the main camera for me.

As @djgriff has mentioned, one of the things that can cause this issue is the use of certain post-processing features on some devices. For us we narrowed it down to the Color Grading effect. Once we disabled that we were able to get past the black screen issue on our older devices.

I have a button in the UI that turns off all post effects, and users with certain Android phones still complain that there is a black screen. I don't have any of these phones myself so it's super hard to debug. Also my game gets top reviews from people who can play it, but has now gone down to only 3 in PlayStore because people with these black screen phones keep down-voting it. It's really discouraging and has hurt my game a lot! Is there no real solution or reason for this?

This will definitely be a challenge to track down without a device to test on. Its not a solution to the direct issue, but if most of the devices to older you may want to consider removing them as supported in the Google Play console.

No noticeable problem when running the apk on my a Samsung J3 phone.

On a Nabi Big Tab I did get the black screen. I have tested many versions of Unity (ibewtween\upto 2018.1.5f1) and found none past Unity 2017.1.1xf1Linux work on the Nabi (kitkat 20inch screen device)

I agree with the comment made at http://answers.unity.com/comments/1474894/view.html

I wonder if this is the cause ... they fixed newer devices...
