I packaged my game and ran it on my Android S7 Edge phone using UE 4.23. There is this weird rainbow effect that occurs on some objects as shown. It even happens on the characters and other environment objects not shown. It is somewhat random, but the ones shown consistently has this issue.
The issue only appears on my phone. When I run my game on my computer using these [settings], I do not notice this issue.
If anyone has any ideas where or how I can start my investigation, that would be great. Thanks!
