On some Apps, screen auto-rotate and maybe impossible to manage app. I install this app https://play.google.com/store/apps/deta ... cker&hl=es and when start, put pressed two second "portrait" button and volia, all app show in portrait.
Just to confirm, yes this works. But also expect some weird results in few cases. I tried the app with one of the nintendo emulators which auto-rotated the screen to portrait mode without the option to change it in the settings, so the above app indeed forced landscape mode perfectly, however the screen was also mirrored vertically (to the side) then. That means, all the text displayed was also mirrored which can be difficult to read when playing RPGs...
