Android 7.1.2 Head Unit - Screen Flipped upside down and reversed. - Android Head-Units

Hi, new to forum, looking for some help please.
I have a generic Android Head Unit for a Mercedes A150 which for some reason has flipped the screen upside down and reversed the screen so to touch the screen, you have to think opposite and upside down.
I have tried the Reversing X Camera Off/on setting in extras. No good. tried reset )push pin in hole). Still no joy.
Any ideas welcome.
I have images to post (and link to) but can't due to forum rules until 10 posts made.

Try the extra settings and change the reverse mirror see if that will fix it.

Is there a way to stop aspec change when keyboard pulled out?

Does any smart person know if there a way to stop the aspect change when the keyboard is pulled out? (Basically so the operating system stays portrait instead of changing to landscape)
Cheers,
Richard

If I understand correctly you mean when taking the device out of the carrying case. The orientation can change when taking it out of the case due to the magnetic catches in the case operating the keyboard magnet operated switch.
If this is the problem then I suggest using a case with no magnets. (a better solution than disconnecting the switch). This however is not the same as not wanting landscape mode when the keyboard is out as the OP wants.
Mike
I remember getting very annoyed with the phone changing orientation when in it's magnetic case when I first got it. I searched and searched for days to find a setting or tweak to fix it. Eventually, I mentioned to my wife that I need to buy a new case.
She said "why don't you put it into the case the other way round?".
I put it in with the screen facing the belt rather than the magnets, and it's worked fine ever since that way round! Felt such an ass!
Sometimes I don't see the wood for the trees me...
I know it's the magnet doing it
I've tried the following:
1. Buy a new case with only one magnet clip (a magnet clip is more comfortable then scotch or any other solution).
2. Reverse the screen to the back.
None works, I think it's the way I pull it out...
Anyway, the only solution doesn't exist, I can't find a normal belt side case.
So my last resort is to find a way to stop the rotation, I always miss calls cuz the rotation during a call slows the device and I can't answer...
I tried to use that registry hack, I followed the instructions and I do not have the rotate icon..even after two resets. Is there any other way to force your screen a certain way?

XTRONS D717AL Screen Problem

Hello XDA members,
I have been following XDA for almost a decade and now came my time to ask for a help.
I bought few months ago XTRONS D717AL. First of all, great player, awesome radio tuner. Catches many stations I couldn't with my old Audiovox and Clarion. It comes With Adroid 5.1.1 and Intel chip. Model number says: Full AOSP on Sofia. MCU Ver: HY_SFY170224EF.
But since day one I noticed a weird display actions. Radio starts right after I start the car engine, display pops-up and on random basis, sometimes the display lights up, sometimes not. It takes about 20sec to load the OS and apparently, the touch screen is working. I know where the Quick settings are, if I pull the top navigation panel down when the screen is in a working state. There is a Light button, which enlights or darkens the screen.
In a dark state (blank), if a pull the navigation panel down when the screen is dark and press the Screen button, screen enlights. I know approximately where this Light button is and pressing it screen enlights. That makes me think, that the screen darkness goes to value 0 at some point before even the OS load.
I have rear camera and DVR attached, but since I took everything away today except the ISO wiring harness, it makes me think that these AV in signals are not the issue. I even took away the reverse camera control cable, illumination cable, and GPS antenna. Brake In cable is fine attached.
Last week I tried to factory reset the unit – no luck.
Flashed with a firmware from the Xtrons tech support – no luck.
I recorded a video today which I uploaded on youtube (I can't post links yet, too young to do that )
Search "XTRONS D717AL Screen Problem".
If anybody ran into such a problem and a solution, will be much appreciated to share here.
Many thanks.
Edit: I just noticed, that upon switching off the radio, the dark display flashes for a half second on its way going in. Possible display cable issue?

I have never tried to go to recovery of this unit. But, I found another topic here:

Regarding my problem, I returned the unit and it was replaced with a new one since it is still in warranty period.

Eonon 2170B issues - parking Camera - Recorder

Hi to all.
I have two issues with the 2170B.
The Back (plate camera) A0115ZP is showing 2 lines when I want to park!! The one is wrong.. is there any way to remove the one?
Also, how can I increase the time of recording? It has a limit of 15minutes.
thanks

Hi! Your unit is an MTCE PX5 so you can head to this forum for any further questions.
https://forum.xda-developers.com/android-auto/mtcd-discussion-questions-development
If it is showing 2 lines, most likely your camera is outputting the lines itself, and then the head unit is adding them too. Cameras usually have a wire loop that you cut if you don't want the lines, and I would recommend this rather than disable the one in the head unit. There is a mod you can do once rooted which lets you customise the lines, angles and distances.
Great! Thanks. I will install the Hal9k Mod v3.1.1.

No power to unit

I have recently changed the screen on my px5 unit and now the unit will not power up. It worked fine before I changed the screen and now there is no power at all.
Is there something I could have done when changing the screen that could cause this? Or if the screen I have been sent is the wrong screen could that cause this issue?
It’s nothing to do with the car as I have put the original stereo in which works fine.
Any help or suggestion appreciated, thanks.
Edit.. fixed now
Glad you got it sorted. How did you fix it in case others have same issue?

Screen Issue

Good Day
Hope that someone can help with this screen issue.
I have a PX 5(rk3368)
MCU = MTCE HF v3.55
The problem is that the screen looks like it is asleep. I see that the screen is active but is very dark. and touch does not seem to work.
My phone is connected via bluetooth and when I receive a call, the screen comes to life and everything works...... but only when the a call is active.
When I stop the call the screen goes very dark again and does not respond to touch
Any reason this is happening and is there a way to fix it.
Thank you

Could be a number of things but sounds to me like a software issue. You can either try updating your MCU or go all the way and install the Malaysk MOD.
Frankly, if you have MTCE head unit, you should really use Malaysk. If Malaysk doesn't solve the issue then it's most certainly the hardware.
Hi
Thanks for the assistance. I reloaded the MCU and that managed to solve the problem. I am running an older version of the MCU than that came with the unit but have not had any issues thus far.
Thanks again
