Hello

Hope you are well.
Does this issue persist when you set the screen resolution to 240x240? I believe that this issue is caused because the resolution also changes or some parameters from the screen are modified.
For the rotation I suggest you use the PXP module, you can find an example in the SDK so you can integrate it into your application.

If you have more questions do not hesitate to ask me.
Best regards,
Omar
