Any news on fix for that? Issue UE-39515 is there since 4.15 version.

Steps to Reproduce:

-Create a UMG Widget that uses the blur component

-Add the widget to your viewport via the level BP

-Pie, observe that the blur works

-LaunchOn or package, install, and open it on an android device

I already saw similar questions and I also face this problem in my mobile project.

I think its because UMG blur not supported on mobile devices. Maybe it will work on some hi-end/metal render, but I not checked. So in my project I just disabled this and use simple mid-black translucent background.

It’s a confirmed bug for over 6 months

Anyone have any work around since the bug exists for version 4.15, 4.16, 4.17 and is scheduled to be fixed in 4.18?

SBackground.cpp

```
#if PLATFORM_ANDROID
// This feature has not been tested on es2 and will likely not work so we force low quality fallback mode
static int32 bForceLowQualityBrushFallback = 1;
#else
static int32 bForceLowQualityBrushFallback = 0;
#endif    

```

If you want to enable background blur on android device(vulkan device?), add option to DefaultDeviceProfiels.ini  
or use commandline.

```
[Android DeviceProfile]
+CVars=Slate.ForceBackgroundBlurLowQualityOverride=0
```

A test doing it on Nexus 5x failed. Either it was wrong to put the file `DefaultDeviceProfiles.ini` in `myproject/config` or it is not supported on older devices.
