I have an unusual problem with a Dell micro projector which doesn't support rotation of the image for ceiling mounting. I need a box which is able to rotate everything (interface, apps,video etc) 180 degrees, I know there are a few apps that can do this on certain boxes and a few boxes which support this in their settings menu.
I am after confirmed products/combination recommendations.
Other priorities -
Fairly cheap
Preferably 2GB
Netflix support
Plex Support
Thanks

Hello all,
this is my first post here so be gentle :cyclops:
I've bought Rikomagic MK802II with Android 4.0.4. with HDMI.
I want to rotate screen to portrait mode. I spent days trying to make it work but without success.
Device came without "Auto-rotation" option in settings. It is somehow locked to landscape rotation.
I tried to do:
1) Unpacked original IMG file, then unpacked system and changed build.prop.
- I've added "ro.sf.hwrotation=90" to build.prop file and flashed the device.
- after rebooting system stuck at loading screen
2) Again fresh start from original IMG file.
- changed "config_AllowAllRotation" from "false" to "true" in framework-res.apk
- packed all and flashed the device
- after reboot system running OK but still in landscape
3) Made file local.prop in /data/.
- In it I've added:
launcher.force_enable_rotation=true
qemu.sf.lcd_density=160
- nothing helped...
4) Changed settings.db.
- changed user_rotation from 3 to 0 (to 1 also)
- after rebooting screen is still in landscape but settings.db doesn't have anymore this row: user_rotation and 20 next rows too.
I also spot some AutoRotationController.smali file but I don't know is everything about it or?
How I testing portrait mode:
- Tried with Rotation locker application
- made my app which have orientation to portrait (tested it on my tablet and on my smartphone and in emulator and in all cases app is in portrait except on MK802II).
Does anyone know what is needed to be changed to get portrait rotation? No matter locked portrait rotation or Auto rotation enable. Just possibility to rotate screen to portrait.
Are there some parameters needed to be changed or some features to be added or something else?
Are there some group of parameters considering to screen rotate?
Any luck with the rotation? Same story on the mk802 fw.
Cheers,
Martijn
Still no luck. I didn't gave up but I need to learn more about android to better understand the problem about rotation and to to prevent/allow screen rotation. That is hard way for me but only because I didn't get any help on the forums and cannot find any blog on the net who have this there written down.
I'm guessing all your previous attempts to configure or manipulate the devices screen orientation are unsuccessful probably because all these system settings, configurations and used apps rely on a hardware feedback of sum sort.
Which probably is absent on these devices.
I don't believe an android stick as this comes with a gyroscopic sensor (hardware). Thus not able to supply or react to the correct information.
I don't think its impossible though, it just needs a more low-level programatically approach.
Good luck :good:
And please share your solution if you get it solved. I can imagine more people are facing this problem.

Hello,
I have been working with one of these devices recently and also needed to display something in Portrait mode.. Alas it's locked in to landscape.
Instead, I figured out a work around. I built an application that is landscape, but the internal objects are rotated 90 degrees. The app I am working on (and hope to have in the app store soon) is a web browser kiosk style app. This application design would allow you to display something in portrait mode even if the devices is locked to landscape. Added bonus, with the way I have it set up I am able to also set it to 180 degrees or 270 degrees (this is useful if the picture needs to be flipped on a projector lets say)
Just thought I'd share what I figured out so far. I'll post the link once I have the app ready for prime time.
Hi,
I'm trying to screen cast from a Nexus 4 to a large screen TV (using a PTV3000). I want to put the TV in portrait mode and have the screen case occupy the entire screen, however I don't seem to find a way to accomplish this. When the phone's orientation is vertical (portrait) it assumes the TV is in landscape orientation and the phone screen is displayed small in the middle of the TV with black space on the sides.
After doing some searching it seems that this behavior can only be changed with a custom ROM, however I haven't been able to pinpoint where in the AOSP tree this behavior can be changed. Any suggestions are much appreciated.
Thanks!

Did you ever get the full screen to work?
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.
Hi.
Just tried playing with RemixOS on a media center pc that I have attached to my TV. At the moment this pc is running a regular linux distro, but I thought it could be interesting to see how Android would work for this purpose. Problem is that my TV is an older 1080p 46" that suffers from an old issue where a large part of the screen is placed behind the massive border on the frame. As such, when running at highest resolution, I loose parts of the screen on each side, top and bottom. I found that running 1366x768 fixes this issue.
RemixOS of cause, is running at 1920x1080 by default, just like any other OS that I have had attached. Difference is that I have no way to change this. I tried changing DPI via kernel boot arguments, but this did not work as it should. The calculations for DPI
Code:
sqrt(1366^2 + 768^2)/46
states that the DPI should be set at 35. But doing so makes everything 100 times smaller on the screen.
How can I get this TV working with RemixOS?
We've got the MediaPad M5 with attached hardware keyboard. (Original Huawei/Fine Triumph Folio keyboard)
In Netflix, as soon as we move the mouse cursor, the video turns black. Sound is still playing, overlays like subtitles and time line are still visible, but the video itself is not. Wait 15 seconds for the mouse cursor to fade away, and the video comes back.
I've also tried YouTube, Plex and the video streaming app for the national TV here, and they do not have this problem.
I've tried re-installing Netflix, rebooting the tablet, changing colour mode & temperature, text & display size, smart resolution, colour correction, mouse pointer size, advanced visual effects, but the problem does not change.
Does anybody know a solution?
I have the same issue but with touch. Idk why
