I need an app that mirrors my whole phone and not just the maps and navigation like in HUD. please help me.
[General Questions and Answers] willfck4beer:
WICKED!!!! Hell yeah! I was just about to ask if anyone had developed a simpler solution. This is brilliant.

Thank you:)
[General Questions and Answers] Aryan Hans:
Need apps not ideas

I am asking for a app that mirrors down my complete phone, I am not asking it for HUD navigation. I am making something like a HOLOLENS, if u haven't yet heard of what a Hololens is then Google it. The one I am making uses HUD principle, I don't need navigation, I need complete phone mirroring.

PLEASE HELP, my email- aryan.hns@gmail.com

THANKS

Wow, I don't think I've seen such a long and old thread with no solution to such a (seemingly) simple problem.

7 year old thread with updates as recent as today, still with no solution hahaha. I checked this thread 5 years ago when I ran into this problem, didn't find a solution, ran into it again now for the sake of using my screen as an HUD, and seems like I'll still be in the same rut.

Is it really that impossible to flip an android screen? that's a shame.
[General Questions and Answers] fleamage:
I'm in a similar situation. My feeling is the same of yours: 5 years with a simple problem with no solution (The problem is simple, the solution maybe not). I guess the problem is not hard at all, I've seen lot of harder problems being solved with creative solutions along many years I have Android phones, developers and hackers (white hats) probably are capable of developing a nice solution, but I think they don't want. Maybe they don't see too much need to do this, it can be a large effort to do something that just few of us will use...

I also think that we are doing a rat race here, we are not draging the "bigger ones" attention. If we really need that feature, we must use the provided methods (like asking for that feature in a kernel development, or by kickstarting a new development) but it must be justified by some useful need.

Thats just my opinion... I don't need that feature anymore (In this years I've changed my cellphone and car already) but I'll be glad if all those people who still want it could get it.

Best regards and good luck!

Yes just the x-axis, but you need to keep the source image, so a dual screen app is needed to overlay screens and send the mirror to the new screen tab

Read this folks

I was googling to find some solution and this came up. Actually this is not a solution to your problems but it looks promising. Atleast this will work.

[General Questions and Answers] fleamage:
Hi thomamvt,

I'm sorry if I didn't get you, but it seems that the mentioned problem (in the post you have linked) is about a guy who have a tablet with a hardware problem that makes its entire screen goes flipped. Are you mentioning that this is possible so we should look for a solution by digging that issue? If that's what you saying, I don't think that it could work, because that problem seems to be a hardware failure, and to solve the problem that user will have to replace the tablet with a new one (warranty).

If you have any ideas, please, share with us.

Best regards!
[General Questions and Answers] thomamvt:
Hi

Sorry, it didnt help. . But i have seen during the search that 2-3 people having issues with the screen being mirrored after flashing a new ROM (mostly with LG tablets, i missed those links, i will try to find it). I think it could be a bug in the display configuration that is causing the flip, if we can emulate that in anyway i think it can be possible. I am also searching for a solution as i have my windshield hud film bought from aliexpress is laying useless as i cannot use google maps in HUD mode.
[General Questions and Answers] nikosbocho:
I am working on a solution that allows you to get a readable reflection of the phone on the windshield. You can use a special film on the windshield (50% reflective - 50% see through) to improve the quality of the image (eliminate ghost image). I have made a working prototype, the solution is simple, compact and doesn't require one to hack the phone. Using it in HUD mode works great at night and also on a cloudy or overcast day but it doesn't work on sunny conditions. On a sunny day one would use it as a regular phone mount on the dashboard. Is there real interest from this community for such a product?
[General Questions and Answers] dovigz:
like this... its ready out there https://www.amazon.com/Techstick-Di...8&qid=1495733011&sr=1-24&keywords=hud+display
[General Questions and Answers] nikosbocho:
The film that goes on the windshield is like the one in the link. The one I am using is made of different material so it doesn't leave bubbles when you try to install it. The big difference is not in the film, it is in the fact that the image reflected off the windshield is the exact image you would see on the phone screen. No need for HUD apps, you can use Google Maps, Waze, Uber, Lyft or any app on the phone.

[General Questions and Answers] thomamvt:
If there is any android programmer out here can easily make it work. I dont have the skills to make it work. But i found this one.

https://github.com/agentdr8/AllyFix5x/blob/master/5xFix/src/main/java/com/dr8/xposed/allyfix5x/Mod.java

This is the source of an Xposed module that will reverse a mirrored application to normal. The degrees can be reversed to obtain the results we all need. Al least for one app.

Vision HUD

The android app you require is Vision HUD. It is designed for use with the HUD or just your window screen.
[General Questions and Answers] pslat:
Phexi was not looking for an app that has HUD mode, there are lots of apps designed to work in HUD mode including your suggestion. The tread is about finding an app that would reverse the display of other apps or the entire device screen. It looks likely that this would require a modified kernel though so thanks for the suggestion.

---------- Post added 13th September 2017 at 12:29 AM ---------- Previous post was 12th September 2017 at 11:37 PM ----------

Hey sumerboard, you are probably nearest to a possible, sort-of solution, have another beer for your thoughts:) VNC displays an image of what is on the screen already so I think this would require two devices, plus some programming. I agree with mcdull in below about the android system and that a full solution would require a modified kernel on a rooted device so this suggestion is a combination of what you suggest and what mcdull suggests in his post #114t:-

Now I know that what he suggests, an app that mirror and flip the screen, is essentially what we are looking for already except that he mentions two devices.

..So if you had the server device running any required app and mounted normally in the car (or truck in your case) with a VNC server running in the background, that device could be linked to a client device running a modified version of a VNC client which mirrors the screen before displaying it - that should work as long as the updates didn't need to be ultra fast - and providing you have access to a spare device for the HUD. The devices would also need to be linked together through wi-fi or bluetooth.

Yes I know that involves editing the VNC client source but the extra overhead to flip the screen would be on the client side and the primary device could get on with the main job of producing the display. No, I doubt I will get around to looking at the VNC client source to do that but this is xda forums.. must be someone here up for that challenge?
[General Questions and Answers] mcdull:
Woo. It has been an really old post. The beauty of having the client server approach is that you really need the primary device that you can interact with to be mounted on the dash board. Or even there are tech to flip and invert the screen, you will need to remove the HUD from wind shield, set it to normal display and operate the UI and activate the HUD mode and put it back. Which is not acceptable during driving of course.

As most ppl interested in this topic has already mounted an android in the 2DIN spaces of the car audio, there will be least effort to add a dump device (preferably OLED) just to mirror and flip the screen. All operation is done on the primary device nice and easy.

[General Questions and Answers] Teadby:
Hi. Don't know if this has been suggested before.. I have been waiting for a way to mirror the screen for hud display of ANY app for years now.... what if you used two reflective serfaces? So have the phone facing down at a 45 degree angle and letting the screen reflect off a mirrored surface sitting flat on the dash then reflected again off the windscreen. Wouldn't the light being reflected twice make it appear normal? Ok so it's not pretty but surely easier than having a whole other device to stream a vnc from. Thoughts?
[General Questions and Answers] Daffy1982:
I know this is an old thead, but I'm still looking for an app like this and can't seem to find it anywhere. Any new information?
[General Questions and Answers] nikosbocho:
I have been working on an optics/mount solution that will achieve this. I attach a photo that I took at night:

[IMG="Google Maps HUD at night, no double reflection"]https://i.ibb.co/5jCqVyq/Google-Maps-HUD-windshield.jpg[/IMG]

For this photo I was using Google Maps, but this would work with any app such as Waze, Uber, Lyft, Android Auto etc. A few other things that might not be evident:

1. The virtual image (reflection) appears to be floating 1m or more in front of the windshield. In the photo the virtual image is focused closer to the white wall. With the current mode of reflecting the phone directly on the windshield the reflection is at the windshield, so the driver's has to refocus close.

2. The double reflection is "virtually" eliminated. It is never actually eliminated but the second reflection becomes more aligned with the first reflection. This will depend on the car, as each car has slightly different windshield.

3. No special wedge windshield or reflective film is required.

So this solution does more than what a software fix would do. Also during the day the "gadget" could be used as a regular mount.

I can't give away the secret but I wanted to gauge if there is any interest in such a gadget.

Finally did it!!

I know im late. But thanks to this thread. After reading all these posts, i was convinced that there are no existing mods, or any other ready made solution available.

So thought of doing it myself. Changed the source and built a custom ROM on top of lineageOS. Added a new option (HUD Mode :cool:)

Here is a working video of my HUD display. cheers. :D

[General Questions and Answers] wen2ri4:
Can you share how to do it in detail?

Thank you so much for sharing this. I can't imgine many people has the same ideal with me, flip mirror the phone screen. But I do this for other purpose, I haven't had a car yet. hahaha
[General Questions and Answers] nikosbocho:
I am not a programmer but I think there might be a way to do the HUD without rooting or hacking ones phone. Split the screen on Android in landscape mode, on the left part of the screen load Google Maps or Waze, on the right part of the screen load the HUD mirroring app. The HUD mirroring app takes a screenshot of the phone every 0.1, 0.2 or 0.5 secs, flips the image vertically, crops out the right half and then shows the image in the app on the right half. When placing the phone on the dashboard the left half is covered with a piece of black cloth or paper card. Only the right half is reflected. There will be a small lag, but if it can be refreshed every 0.1secs then it will probably not be a real problem when driving. If it can be done continuously then the lag can be eliminated.

The disadvantage is that the image will be a little smaller and have more square proportions. However the advantage is that this could work with any app that is displayed on the left side of the split screen, Waze, Android Auto etc. Also, since the image is smaller a smaller reflective film can be used on the windshield to make this visible during the day.

Is this possible with an app? If so, is it easy to write such an app?

Hi guys, any updates on this?
[General Questions and Answers] ciobi:
I've been thinking about doing this for more than 10 years now, and last week I finally spent a few days to work on it and ended up with https://play.google.com/store/apps/details?id=tech.ciobi.mirrorscreen

It's in beta, and all sorts of things could be improved (like battery life or color processing), but let's see first if there's still any interest in this.

Here's an actual picture of my windshield, with the HUD mirror and the phone running Google Maps:

[General Questions and Answers] ashish_jha:
Good app but need to adjust too much. Need to automate the adjustments to make it user friendly.
[General Questions and Answers] ciobi:
I totally agree that the setup is a bit of a pain, and I have an idea on how to improve things, but it's also not particularly nice, and might not work all the time. (It involves creating a new, simple app to run it in the other half, to calibrate the main app. Then I could see exactly which part of the screen is taken by Half HUD and which part is used by the app you want to project.)

Also, I don't expect improving this would dramatically change the adoption, which is at a grand total of 21 users after it peaked at 23 a few days ago. My question is: After taking the time to set it up, is this something people actually want to use? How many?

Anyway, when I find some time I guess I could try the approach I described above, to see how well it works. Or, does anybody have a better idea?
[General Questions and Answers] ashish_jha:
I think a better idea would be a full screen mirror flip with a small floating widget on top to bring to normal as and when needed.
[General Questions and Answers] ciobi:
Anyway, when I find some time I guess I could try the approach I described above, to see how well it works. Or, does anybody have a better idea?

Sure, but I don't think it is possible to do this in a reasonable way. I'm pretty sure you'd need to root your phone, and interfere with the screen drivers to make them flip the image and the touch input. These would quite likely involve significant effort and be model specific, at least to some extent.
[General Questions and Answers] ashish_jha:
The first thing I do after unboxing a phone is to root it. There is no life without root ! 😀
[General Questions and Answers] mladen074:
Google will never implement this feature willingly, considering it directly competes with their Android Auto, which they want to push as a default navigation app for everyone. They like collecting private information, and driving habits are so attractive to Google, they would be idiots to implement this feature and ruin the advantage their app has over other apps. It's not gonna happen, at least not up until they decide they have the absolute dominance with their Android Auto app, and don't feel other apps will be able to endanger that dominance anymore.

That being said, the only thing we can do is to modify the source code and change the display driver to invert the coordinates. It's a fairly easy task, but for someone who knows how to write such code. Here on xda I've seen a lot of smart people, capable of doing such stuff, so it puzzles me noone has took the opportunity to write it. I can only imagine there is something more to this feature than meets the eye. Until then, 2 mirrors in the car, under the windshield, can do the job.
[General Questions and Answers] Parmeet.sethi:
This is great! Thank you for developing this application.

I guess a part of the issue with adoption is that folks looking for something like this might not know where to look or how to find it.

Case in point, I stumbled on this thread after not finding anything on the Play Store or YouTube. Maybe a bit of SEO and backlinks from YouTube could help get the word out.

Consider this video that appears on top when searching for "Google Maps HUD". If the comments (and like counts) indicate anything, at least a hundred people may have entered that exact query in search. Note that the video has has around 50k views, which is much higher than the channel's average.

A similar video covering this app would certainly encourage adoption. I'd be happy to help out and take this up as a holiday project.
[General Questions and Answers] ManagementCritic:
If I may be so bold as to make a suggestion, how about this:

First get a phone with support for USB Type-C (DisplayPort Alt mode) transmission (like a Galaxy, Pixel, certain Mac and IPads and windows devices; if you don't already have one).

Next get a USB Type C to HDMI Hi-Res Cable with USB Power Supply Charger Cable.

Then, get a small teleprompter monitor that supports both vertical and horizontal image flip. Most are designed for high ambient light level use and have a adjustments for brightness and contrast (and everything else).

You will also want some type of light gel or film to help reflect the image.

If you already have a device with USB C DisplayPort Alt mode, then you can get out at anywhere from $200-350 total. Compare that with the cost of your time to develop the app and how much time you want to spend in development and testing.

Of course you can still connect your device to the car audio via bluetooth. Then you can use your device as normal without any hassle. Just a thought...
[General Questions and Answers] ManagementCritic:
You may also wish to checkout Open Broadcaster Software. It is a free and open source software program for live streaming and video recording. Features of the software include device/source capture, recording, encoding and broadcasting.

Short version is that you can use it on Windows, Mac, and Linux devices to flip an image via software, so any HDMI monitor will work for your HUD. A small tablet and a bit of velcro might be nice for this project... ;)

Good luck!
[General Questions and Answers] PhotonIce:
I don't know why a thread from 2012 has been bumped, niether have I read any messages after the first page, but my simple question to everyone here is:

Why didnt anyone use an ACTUAL mirror to mirror their phone screen?

Invert the phone screen once with a real mirror so that its backwards, then when it reflects onto the windshield it'll invert itself again; simple as heck!
[General Questions and Answers] ManagementCritic:
Just off the top of my head, brightness will diminish by distance squared, so it would get very dim very quickly. Not so good in even dim lighting much less in daylight. Second, in most cars there isn't a lot of room to squeeze in your device, a mirror and room to reflect off the windshield. Have you drawn this and diagramed how this idea would work? Finally, I believe the image would be flipped vertically, not horizontally. So, maybe not so simple.
[General Questions and Answers] PhotonIce:
1. Of course it'll be dim, but to be fair, your phone screen isnt too bright to begin with, so unless your using a modded lcd panel, its gonna be dim either way.

2. I've done this myself using a mirror (phone reflecting vertically on the right side of my windshield, it takes up a little space, but you dont use the space of the right of your speedo anyways..)

3. Hold your phone infront of a mirror, it will reflect it horizontally. then upon reflecting again off of the windshield, it will flip horizontally again and become normal. You can even try this at home by taking two hand mirrors, and reflecting your phone onto one mirror, while reflecting the image from the 1st mirror onto the second mirror, then look at the image on the second mirror, it is normal again.

It would only be flipped vertically if your were using a lens, which we aren't using here.
