Hello,
Trying to do some research on how the Joying Intel Sofia units display the reverse camera, to see if there is a way to implement viewing at any time ( not just during reversing )
Reverse Camera works before Android has finished booting, most likely a basic Linux kernel with camera support, present in one of the SoFIA Virtual Machine partitions.
Once the Android has booted, SYU-1-C9-UIServer-V1.0 takes over, and does the rest. I believe it handles displaying the Reverse Camera video feed, as well as blocking the rest of the android UI from being accessible, and displaying the Video Adjustments overlay UI. Originally I believed that the MCU was taking over the display, but this was contracted when I enabled triple-tap zoom in accessibility settings ( using the AOSP Settings.apk ). I was able to zoom and move the screen around, definitely not the MCU locking us out and doing things on it's own. See video demo here:

If you disable SYU-1-C9-UIServer-V1.0, you will find that placing your vehicle in Reverse no longer automatically displays the Reverse Video UI, or block the Android UI. For those of you with hard buttons, some of them may be disabled while in Reverse gear ( unknown what detects this at this time ). AUX and RightCamera, as well as Sofia-1-C9-ExDvr-V1.0 will display a black video image, or have the current video input image freeze while in Reverse gear. Correct video will be restored once you are out of Reverse Gear.
I also discovered another APK, Sofia-1-C9-RightCamera-V1.0. But this just seems to mirror the AUX input, without Audio. The only way I can launch the RightCamera app is using Nova Launcher's Activities Widget, selecting Sofia-1-C9-RightCamera-V1.0's Main Activity. The upside to this, is unlike the AUX Sofia-1-C9-Aux-V1.0 App, Sofia-1-C9-RightCamera-V1.0 doesn't pick up the audio input, so it doesn't mute all other apps while viewing the video feed. Now I can view my dash camera's live view, which I have hooked up to the AUX input at anytime, really cool! ( need this for reverse!!!! )
Also, Sofia-1-C9-ExDvr-V1.0, when run, always displays a "No video signal detected" message with the cloud background.
Perhaps we can modify Sofia-1-C9-RightCamera-V1.0 to access the Reverse Camera? @gustden, @surfer63, @@AssassinsLament, or anyone else who is knowledgeable with these units and smali, could you guys take a look at UIServer and RightCamera to see if maybe this is possible? I've been looking around, but haven't found anything useful so far.
I have run apktool d on all the Allapp.pkg files, vfor the latest 03_28 firmware, available at pending link if you want to save some time and don't want to run apktool d on them yourself.
I'm also interested in this. Our previous MTCD with RK3188 was able to access the reverse camera with the Fcam app.
Nice find with the Sofia-1-C9-RightCamera-V1.0 :good: Will link to this on home screen to preserve music. Thanks!
OK. Backup camera seems to show up as a rear camera to android.
Try this:
Code:
Reboot Unit.
Install Open Camera ([url]https://play.google.com/store/apps/details?id=net.sourceforge.opencamera&hl=en[/url])
Once install is complete reboot unit
Launch the Open Camera app as soon as the unit is back up
stare at the live video of your rear view camera feed displayed.
Photo's don't seem to work in Open Camera. In other camera apps they turn out green. Tiny Camera shows the same green image. Camera MX takes green photos. See attached photos.
If you open the AUX or RightCamera applications, then you can not use any app to view the live feed until you reboot. For some reason they seem to lock the stream preventing other applications from accessing.
I ran across this while calling my friend on the head unit using hangouts. Normally, i do voice only call, i clicked the wrong button (video call) and there i saw my rear camera feed as I was driving. lol. Now if we could only get the aux video input as a front android camera...
I tried using open camera on my joying intel and it works but only if you haven't reversed yet. Once you go into reverse, you will not be able to access the reverse camera again until reboot

Any progress with this?
Also, has anyone found a way to show an image layout (guide lines) on top of front camera? I was trying to find an app that shows an image overlay on top of Android and I found one:
DesignOverlay but the problem is that once enabled it will show on top of all apps. I would like to find out a way to just show an image overlay on top of Sofia-1-C9-RightCamera-V1.0. This way I could use my own .png file to show guide lines that match perfectly my car (.png created with real life measurements around the car).
Any ideas? Practically I would need an app that launches two apps at the same time and exits both once the app is exited.
Hi, I am just playing around with the settings in gamebooster and have the feeling that something isn't working correctly.
For example:
I edit settings (resolution) of Super Mario Run and save the settings.
Then I reopen the game, but after that I can't press anything in the game (no recognition of touch input)
Then I have to reboot the phone.
Kill the game from Multitask-Windows doesn't help.
Moreover Mario Run is listed as a 120Hz compatible game on Razer homepage. But with 120hz it stutters on my device. Have to set it to 60hz.
Do your game work correctly if you edit settings and reopen the game?
And how do you configure your Game Booster?
I'm using the custom settings and also experience odd behaviour. When switching resolution with summoners war I can't close menus via the x-buttons. They're simply not touchable.
I don't have to restart the phone for changes to take effect.
I did further testing. Yes, the only problem is switching resolution. It only works if the in game booster selected resolution is the same as the resolution in device settings.
Otherwise something is wrong with touch input.
And yes, reboot is not needed after change of game booster settings.
For summoners war only the 1440p resolution works even though I use 1080p as system setting.
So, it seems that some game have problems with resolution change in game booster.
3D rendered games seems so work with a resolution change, but some of my 2D games (like mario run) dont work with a resolution change.
Moreover:
Is antialiasing on, when the slider is on the left (greyed out) or the right (green)? (The description is a bit confusing).
Moreover do you see a optical difference between on and off? I cannot see a difference.
Is there any posibilty to record in 24fps? None of the playstore apps allows that. It must be locked by oneplus deeper in android. Maybe some magisk module?
Dear Friends
I own POCO F2 Pro and I have noticed, when playing game Clash Royale (it's forced to fullscreen, because it's compatible with it - I cannot disable fullscreen, because it's grey out in options of Fullscreen Apps), upper corners are cutoff. It looks like, whole screen is moved in up direction in such way, that bottom is higher, then it should be.
Are there any possibility to disable Fullscreen mode for application, which is marked as compatible and there is no possibility to set it off?
May you download Clash Royale for free from Google Play and check, if you have the same problem?
I have the latest MIUI Global 12.0.2 Stable 12.0.2.0(QJKEUXM). Android version 10 QKQ1.191117.002.
I would be glad for any help and support.
Sincerely
I have a Sprint version A32 5G. The new One UI removed the hide camera cutout option. Although I installed the Nacho Notch it only allows me to hide when in portrait mode. When I watch movies on the Amazon app horizontally the cutout is blocking the content. Any thoughts? Best wishes to you all.
