Currently, when you connect an external monitor to an Android phone that supports mirroring, the phone makes the assumption that the external monitor is set up in a landscape orientation. Thus, when the phone is held vertically (in this case, the Galaxy S III) in a portrait orientation, the video output on the display is portrait, but centered with black bars on either side. Of course, when the phone is held horizontally, the output fills the external display.
What I'm looking for is a way to force the Galaxy S III to mirror its screen such that when it is held in a portrait orientation, the output will fill the external display. It would have to work across Android - I'm not talking about a specific app in particular, it needs to work consistently across all apps.
The external display would be mounted vertically, so it's essential that the output from the Galaxy S III while in portrait orientation completely fills and has the correct orientation on the external display.
I have a galaxy nexus, and just bought the mhl hdmi adaptor, i've managed to lock the phone on is portrait mode but this rotated the image filling the whole screen. Basically requiring me to turn my head to see properly. Is there any way to rotate the image vertically and have black pillars on the side?
I need this for a presentation of a portrait application.
Hi, my I9100 when the phone is set to auto-rotate, and is in landscape mode, it will not return into portrait mode. Not even if i set it to no auto-rotation. It runs KitKat (Beanstalk) and even if i manage to get it to portrait, the apps that were viewed in landscape will remain in landscape.
Every tme the only solution is to reboot.
Its defently not a hardware issue, but i have noticed while using apps that show the orientation of the phone such as Bubble level, that the phone doesnt detect when it is faced bottom side, up.
Please help
hello everyone,
I'm having a problem with the rotation of my android device and I was hoping if anyone could help me with this.
to give some backstory, I'm trying to create a magic mirror using a MK809 III B Quad-Core android stick, which uses android 4.4.2
the stick is used with a computer monitor (Samsung Syncmaster 205BW), but the monitor will be used vertically. (I'm using a HDMI>DVI-D adapter to connect the two)
because of this, I need to have the screen rotated 90 degrees in portrait mode, and android does allow you to change the rotation of the screen, but it doesn't do it well.
normally the rotation is set to landscape, but you've the option of setting the rotation of the screen, but if I set the rotation to 90 degrees, rather than actually rotating the screen with 90 degrees, it rather pushes a vertical screen in landscape mode, thus cutting off half of the screen.
so far I've tried apps such as Ultimate Rotation Control, but those do not actually rotate the screen, rather they just lock the rotation.
my question now is if anyone can help me with this problem, or tell me if it's even possible to do the thing I'm trying to do.
Any Luck?
I'm having the exact same problem with APQ8084 SOM running android 5.0.2 outputting to HDMI monitor (no accelerometer).
You would think this would be an easy problem to solve.
If I put my Winodws 10 Monitor in portrait mode, it correctly rotates screen 90 degrees end of story.
As Yusunoha mentioned, changing the user rotation in Android (via several methods):
1. using the "settings put system user_rotation 0/1/2/3"
2. modifying PhoneWindowManager.java to always return preferred rotation as "portrait"
3. Setting "persist.panel.orientation=90/270"
Does NOT result in screen rotating 90 degrees.
Instead I get a compressed portrait mode stuck inside my landscape orientation.
It's almost as if the accelerometer (which I don't have) is telling the OS to always orient towards it's perceived gravity.
Any tips rotating the entire Android Display experience (not on a per APK basis) would be wonderful.
Anyone have any ideas?

Found any solution? Even with my rooted device and these settings it won't work. Also using usb c > hdmi > vga.
Hello! I bought a huwaei media tab 3 for a car installation. i open the device to solder a cable to the power button. after that i noticed that the device oriantion is the opposite of what the divece is actually is. For example right landscape is now left landscape. Auto rotation works it detects the change of orientation and changes modes only they are inverted. I tried factory reset still the same problem. What can i try? sure i didnt touch or break anything cause sensor works it detects movements.
