Default Stop Camera & keyboard from going to portrait when close

i wanna use my phone in landscape mode. however, it's a big hassle when the keyboard (or camera) always puts the device back in portrait when i close it. it switches the screen back to portrait when i close it, even though the screen was in landscape prior to opening the keyboard and closing it (or opening the camera app)

i don't think it's a regular setting thing. it may require some registry tweaking or an external little app to stop this behavior.

can anyone help? it's very annoying!
