When I position buttons group on bottom of screen (using getSafeAreaInsets() function insets or display.safeActualContentHeight + display.safeScreenOriginY - buttons.height) it works fine on simulator, Google Pixel 8 with Android 14 and some Motorola device. But on Samsung Galaxy S22 Plus and Galaxy S23 Ultra (Android 15, oneUI 7.0) system UI i rendered on my buttons. When I have upgraded my Pixel 8 to Android 15, I have the same problem with it.

Google Pixel 8 - Android 14

Google Pixel 8 - Android 15

Samsung Galaxy Galaxy S23 Ultra (Android 15, oneUI 7.0) or S22 Plus
