well the problem is that you wrote your program for android 11 and that is why it is shown and performs differently in older versions of android if you wish to make it work the same on all devices then you should choose an older SDK version preferably one that is compatible with version 5; But if you do so you might not be able to use some of the new libraries or packages that you used for android 11.

Make sure the version you are applying on other devices is supported. If you are still experiencing crashing, please share the error code with us.
