I liked the One-handed mode in Android 11, because we could access to the entire screen with the thumb finger, since the main future of the app was to zoom out the all screen of the mobile to ease access.
Now, in Android 12, the app is screwed, since I can't adjust the dimension of the screen, I can't use only one thumb because the width is the same as the original screen, I can’t change to use the right or the left thumb, and I don't see the entire screen.
Why Sony, why ???

How could you ruined a good app ?? Can I have the Android 11 App in the Android 12 ???
