The Android 15 introduces the change https://developer.android.com/about/versions/15/behavior-changes-15#textview-width

Which is "on" by default from Android 15 and later
https://developer.android.com/reference/android/widget/TextView#setUseBoundsForWidth(boolean)

TextView is directly used in QPA Android at two places: 
https://code.qt.io/cgit/qt/qtbase.git/tree/src/android/jar/src/org/qtproject/qt/android/EditContextView.java#n35 
https://code.qt.io/cgit/qt/qtbase.git/tree/src/android/jar/src/org/qtproject/qt/android/QtMessageDialogHelper.java#n161 

The change might cause TextView and classes inheriting from it to take more space with complex letter shapes. This suggestion suggest that complex letter changes should be tried on Android 15 and later especially on the two directly used classes to see how does the "on" by default impact to them. End user can control "on" by XML and set it as "false"
