URP - Construction deafult scene built to Android, only 1 light produce shadows

Hi Guys

in 2019.3.0b12 and URP 7.1.5 with starting a new scene using the URP template, I switch to Android build, remove vulkan, the build to my Android Phone. However, as you can see, the directional light works as expected by producing light and giving shadows, however the construction light (spot light) just seem to give light but have no shadows.




1 - Why does the spot light not have shadows (it does on pc, but not on android)
2 - Why does the directional light shadows that the wall create, look so uneven, as if there are spikes on the wall. IE the shadows are not sharp?

Do I perhaps need to change something here:?
