Unity URP 2D Point Lights not working on certain android devices

Graphics Render Pipelines

Hello everyone,

I created a scene in which there’s a day/night cycle. It runs fine on every android device that’s been tested so far, but not on honor 6x.
See expected and what i’ve got in attached files.
I really don’t know what to do, UI renders fine and non-lit sprites render fine.
Additionnally, Light 2D set to “Sprite” works.
I’ve got no error messages and i don’t have access to the device to run big tests.
Any help would be really appreciated!

Thanks for your help!

Any errors in logcat?
Did you try OpenGLES3?
Which Unity version?

Thanks for your reply,
No errors in logcat (I didn’t get any report from the user and there’s a ui button (thus visible for him) that pops whenever an error is caught
The graphics API was in “auto” mode, but when i unticked the setting, i got this:

I am under Unity 2021.0.6f1

  1. Update to the latest 2021 LTS, there have been fixes.
  2. Remove vulkan from the list and try again
  3. Logcat logs more than just errors. Also warnings and regular logs. I suggest to check it

Thanks for your insights!
I was reluctant to update Unity because i once got errors after updating, but i guess since I stay on 2021 it should be fine?
Removing vulkan won’t deteriorate QoL of higher end mobiles ?

2021.0.6f1 is not a unity version, so I cannot say for sure.
But usually updates withing the same yearly release go alright.

And unless you use VFX graph or very heavy compute shaders, OpenGLES3 is better for mobile games on the broad scale. Vulkan might a slight improvement in performance on the latest and greatest devices, but I usually suggest to use OpenGLES3 for android games

Sorry, I am on 2021.3.6f1
I tried both upgrading unity and disabling Vulkan (letting only OpenGLES3) at the same time, but the issue persists…
It’s really weird tho, it only does it for one device, is it theorically possible that a device couldn’t run 2D point lights ?

The docs say there is no extra required compatibility.
So update to the latest 2021lts and if that doesn’t work I still highly recommend checking logs at startup etc

I got logs back -every log- and i couldn’t find anything interesting.

I got some

A scripted object (script unknown or not yet loaded) has a different serialization layout when loading. (Read 48 bytes but expected 68 bytes)
Did you #ifdef UNITY_EDITOR a section of your serialized properties in any of your scripts?

and

The referenced script on this Behaviour (Game Object '<null>') is missing!

The referenced script (Unknown) on this Behaviour is missing!

But that’s messages i also get from other builds that are totally fine with the lights…

Here are some informations about the device

Is there a chance you are using too much memory? How much memory is in use by the game?

I’m beginning to think it’s just a device with shitty drivers
