Regarding of the Android on Xperia models (XA2 dual sim in my case):
"Rotation of Android apps fixed (it follows the option chosen at Settings > Display > Orientation)
"
Temporarily disabling the dynamic rotation by pressing a finger on the screen still doesn’t work properly for the Android apps. When you press a finger on screen, when flipping the device, the current orientation stays locked only as long as your finger stays on the screen.
As soon as you take your finger off the screen, the screen will rotate to match the current orientation of the device.
