Screen shows a little blink before the Unity loading screen. I’ve tested this in my current project, with a brand new project, and in two different phones (Oppo A73 and Moto G). It happens everytime the app gets cleared from memory.
I’ve also tried it in Unity 2018.3.0b1, having the same issue, and in Unity 5.6.6, without issue (it also has a different default splash screen).
Currently using Unity 2018.2.7f1 Personal.
Has anyone got any idea or has seen similar?
