    I use Q5.15.2 to make an Android app, a simple qt widgets application, with only one button on the ui.

    I installed the apk on a tablet with android13 version. After the app is running, I press the power button of the tablet to turn off the screen, and then press the power button of the tablet to turn on the screen. The app interface is displayed, but the interface is in a frozen state. When I click the button, the interface does not refresh at will, but The button click event is called, why?

    There is no such problem when making Android programs on Qt6, but my code was written on 5.15.2 and I don't want to upgrade. How can I fix this problem on 5.15.2?

    Can someone help me compile Android programs for versions 5.15. X above 5.15.2 to see if this problem can be reproduced?
