Hello. I am developing a game for the Android platform. The buttons work well after building for Android. However, when I rotate the screen, go to the home screen and return to the game, or enable airplane mode, the buttons become unresponsive. It feels like the focus is lost. It’s not that the touch input is completely unresponsive; when Touchscreen.current.primaryTouch.press.isPressed is true, I can see the correct position with Touchscreen.current.position.ReadValue() . I haven’t changed any settings related to the canvas or Raycaster. Currently, there are three canvases in this scene, and all of them have the Render Mode set to Screen Space - Camera. When I test with just one UI element in a test scene, it works correctly. Additionally, it also functions properly when built on the Android emulator. However, this issue occurs on the device I am currently using. Does anyone know why this problem is happening?
