Custom programmed nfc tag ideas.

I bought some nfc tags from the good people over at tagsfordroid.com and took the weekend to program a few of the tags. I thought it would be cool to list some of the programs/actions people have programmed into the tags so others can get some good ideas.
Program: NFC Task Launcher.
Work tag:
~switch tag.
1. Get to work:
Disable wifi
set ringer type vibrate
set brightness to 26
disable bluetooth
2. Leave work:
Enable Wifi
Set Ringer type Normal
Enable Auto-Brightness
Ringer Volume 7
NFC on key chain.
~switch tag.
1. hotspot on:
enable portable hotspot
set brightness to 16
disable wifi
disable bluetooth
2. hotspot off:
disable portable hotspot
enable wifi
enable bluetooth
enable wifi
That's all i have for now. lets see what else everyone is programming into their nfc chips.

i also put an nfc tag by my calendar at my work to pull up my calendar app when i tap my calendar.

good article i saw that one when doing a search.
Just thought it would be cool to actually show the action items that were posted to the tags so someone could reproduce it if they thought it was a good idea.

has anyone figured out how to turn on and off an exchange account with NFC? I would love the tag that i use when i leave my office to turn on my exchange account mail so i can get my e-mail while im at home. I dont need it on while im at work because im in front of a computer all day and have access to my e-mail.

I'm sure that you could set something up using a combination of NFC Task Launcher and Tasker.
Also, while I'm tooling around trying different tags, It seems that placing tags on a metal background causes them to not work... I have had no success placing them on the side of the front door (metal door...) so I can touch it on my way out the door. Also all the desks and everything else for that matter is metal at work (Navy) so placing a "work" tag has proven to be rather difficult to accomplish successfully... May have to try different types of tags to see if there is success with another type.

Get metal isolating tags, they have an isolation layer between the IC and the surface you place them on so they work on metal. They are a bit thicker as a result.

place them on so they work on metal

There is a mod in the EVO 4g LTE and HTC one x forums that let's you choose when NFC can be read.
Screen on and unlocked,
Screen on and locked, or
Screed off (obviously locked)
I modded the phone to read tags when the screen is on and even if the phone is still locked. Allowing it to read while the screen is off may be a security risk for some.
Anyway,
On my keychain:
Switcher:
WiFi off, Bluetooth on, volume up, brightness up, latitude check in, plays media player.
This is great because it automatically connects to my car Bluetooth headset and the HTC aux stereoclip so music starts playing through my car speakers wirelessly via swipe of the keychain.
Tap again to disable all these and check in again w latitude.
I also have a separate tag in my car low on the dash to enable GPS and open maps so I don't have to fiddle w my phone througg the settings and open the app drawer to open maps. Makes driving that much safer. Also, I don't always use GPS, so having a separate tag for it from my keychain saves battery by using it only when needed.
Trying to set up a tag to enable WiFi tether for root users and stick it to my laptop/pc for quick swiping and enabling. But that has been tricky as you either have to use tasker or a custom activity in NFC task launcher.
Can't think of any others relevant to my interests. I don't see the need in making 38583983 tags. I definitely use the ones in the car tho.
I may order a wristband and think up something creative for it. Assigning a "sync all" activity would rock for it as I keep auto-syncing on my phone off and only sync email and such when I see fit.
Phew.

For the two of you who permanent contact?
For example, I have a car dock in my car. My thought was to put the NFC Tag sticker on the back of the dock so when I put my phone in the dock, it would obviously hit the tag and trigger my car settings (wifi off, bluetooth on, etc). Then when I removed the phone from the dock, I'd want it to trigger other settings (bluetooth off, etc).
Since the phone would be constantly against the tag, though, would it be continually triggering switches back and forth? Or would the initial switch trigger upon putting it in the dock, but in order to trigger the 2nd switch upon removal I'd need to move it away from the tag, then tap it back on the tag to initiate another trigger?
Thanks for your help. Trying to fully grasp how the NFC tags work.

With android there's no indication that a tag has gone out of "range" broadcast to the system. Essentially to get the tag to re-fire you'd need to either move out of range and then back in or turn the screen off (disables NFC) and then back on and unlock the device (restarts NfC and re-reads the tag).

Two important points
1) NFC doesn't usually work with screen off, so you either need to patched NFC.apk (for example AOKP b40 has this feature) - otherwise, everytime you switch on screen, it would trigger the tag again
2) there really is no way to trigger action on tag removal
I solved this (sort of) by having two tags - one in dock and other one that resets to "default" settings that I swipe after I leave. Not pretty but working...
Or you can set the actions as toggles, so one touch - set for dock mode, and second touch - revert back. But it obviously doesn't work for everything.

Simple solution to that, get an app that detects other hardware features so it can detect when its being moved, ie proximity detection, orientation.
You could also get a fabric nfc tag and sew it into your pocket?

I created a tag that does the following:
->Turns WiFi on
->Waits until I'm connected to my home WiFi connection.
->Sends a WOL packet to my desktop at home
->Wait 20 seconds
->Turn Wifi Off
So when I get home from work I can put my phone down on the tag and my PC will automagically begin booting

For the obvious uses, don't forget night mode - turn ringer off (or on, depending) turn off mobile data, connect to home wifi, etc.
If you just want to mess with tags, go to your local tmo or bestbuy store and pick up a pack of the samsung tectiles. They aren't as cheap as you get online ($15 for 5 vs $1-$2 each) but they are decently large and work just fine. Once you run out you know its time to order a bunch, and you'll probably have a better idea which ones you want to order.
As an old-school embedded hacker, does anyone know of a vendor that sells the DESfire E2V tags with a tag dev kit? I've got a bunch of ideas for cool apps, but I need to be able to modify the OS on the tag. (Take a look at the specs, its pretty neat. up to 32k of storage, with security etc, all running on an old Intel embedded CPU from the 80s.) The only ones I've found so far have the firmware distinctly read-only. I suspect it is using the on-chip ROM, which means it would take impossibly delicate surgery to replace. (There is a pin that toggles between booting on-chip and external.) In theory a dev kit would be set to external and come with a jig or other tool to write it, as well as OS binaries for the standard NFC OS..
As a random easy example of stuff you could do, think of a write-only tag that took vcards for a mailing list (or a roll call) but didn't let anyone but the authorized user read them out again. Right now you'd need to put a full embedded computer behind an active NFC module to do that - a lot more expensive and more failure-prone than a custom tag..

I had problems with double-reading when I'd fumble putting the phone in the car dock. It snaps into place the dock, and it would sometimes read when it got close to the dock, then again when it snapped into the cradle.
I put the tag on my sun visor instead. Sit down, touch the phone to the visor, put it in the car dock. Arrive at work, pull the phone from the dock, touch the visor, and go.
Same thing with my at work tag - I put it on the side of my desk so it wouldn't re-trigger if I removed the phone from my work dock to answer it.

Anything is possible with Tasker

You can definitely do "IF" commands if you use Tasker along with NFC Tags. Since Tasker doesn't natively support NFC, switch isn't a possibility, but since switch is built into many NFC apps, that's an easy one.

I programed my vcard on a tag and put it in my wallet.. Instead of exchanging info if they have an android or blackberry with nfc I just hold my wallet to their phone for a second and it will open the vcard on their phone and ask if they want to save it.
The tag is always in my wallet ready to go.
Surprisingly I've used it more then I thought I would already.. It's kind of fun also and people get a kick out of it.

Samsung Tec Tiles (NFC)

I don't really understand what makes these better than NFC tags that you can get from Tagstand for much cheaper. Anyone got an answer?

How do you program them? Just wave it over your phone and do it off the phone?

They are normal NFC tags. They have not introduced anything new.
They are programmed using any NFC writing app. Once you have decided what action or content to write, hold the phone over a blank tag under the phone's NFC antenna (on the battery). The rest is quick and automatic.

Apart from them looking good, they are just like any other nfc tag, but more expensive, I wonder what size they are.
Right now I use these token coin type nfc tags cost only USD 0.32 each, the size is only 24byte usable memory, enough for basic toggle, alarm, phone adjustment functions.

They are available in carrier stores so people can get some instant gratification.

Their app will work with regular NFC tags as well. I played with it for a few minutes. I think I will stick with NFC Task Launcher.

Is Tagstand the cheapest place to get tags at?

i'm not sure what these are even needed for. the only thing i could possibly see using one for myself, is having one in my car to switch on bluetooth.

There are lots of potential uses. The one you mentioned, you could set up a "Do Not Disturb" iOS 6 style function for your bedroom, an airplane mode tag where that may be needed (on my bike when I get to work and put my phone away), etc.

You need to be more creative, that's all. Here are my uses so far:
1) One in the car dock (vzw) that enables GPS, disables Wifi and runs Car Home
2) One in my wallet that runs the Bank of America app
3) One at each entrance to my home (front and back door) that works as a switch. One tap enables wifi, connects to my home network, disables GPS and turns all volumes up, and a second tap turns off wifi and turns on GPS.
4) One on my desk at work that lowers the volume, enables Wifi and runs the clock app
5) One on my external speaker that turns the volume up to 75% and runs Pandora
6) One on a stand in the kitchen that will run a recipe website when I put the Nexus 7 on it (haven't decided which site yet)
Other cool uses I've heard of:
-Putting tags on spices in the kitchen that searches for recipes with each spice when you tap it
-Using it for Geo-Caching, so that when people tap it it automatically notifies you or posts to a website
-Putting them on business cards to share your contact info. Have people tap their phone to your card, rather than having to give them a card they will probably just throw away anyway.
-Bluetooth pairing (I don't have any BT devices currently)
The possibilities are endless, it seems, you just need some inspiration. These Samsung tiles look nice, but they are too expensive. Just get some from Tagstand or a comparable vendor.

Do I understand correctly that all I need are the tags and no usb reader/writers?

Wow, that'll take a hell of a lot of tags for most people, I would think Definitely a cool idea...it'd be nice to use it for inventory, even though that's probably something better suited for RFID tags.

Nope, just tags, nfc enabled phone, and a free app. USB has nothing to do with it.

I have one on the center console of my car. It would s set as a toggle.
Tap when getting in the car: bluetooth on, ringer and notification volume full.
Tap again: Bluetooth off, ringer and notification to vibrate.
I drive a Ford and this allows my phone to automatically connect with the Microsoft Sync system giving me Bluetooth control over calls and music with steering wheel buttons and voice commands. When I'm done in the car my phone goes silent so I'm not disturbed when in meetings.

interesting..how long does a tap take to register?
also can tags toggle wifi on/off? or are they just assigned to on or off?
and can a single tag turn wifi on, blue tooth on, max volume, and start a program?

Just a second!
Its up to the app you use to read them.
I personally recommend NFC Retag because it lets you use old, locked tags, has a ton of functionality, more everyday, a writer, and there is a free version!

awesome! thank you. so I know a tag can be used to turn on an app such as spotify; can it also be written to start a song from the app?
also do you literally mean a second?

Does the writable space really matter on these? What I mean is, can I just buy small 46 byte NFC tags and program them to toggle Tasker profiles?
EDIT: Apparently you can set a url to run any tasker task using this.
https://play.google.com/store/apps/...NvbS5hbGVkdGhvbWFzLnRhc2tlcnVybGxhdW5jaGVyIl0.

I also use NFC Tag in every day use, like changing the setting of my phone when I come in/out of my home (Wifi, sound and cie).
I ordered my tag from TagStand and also use the app they build. This one is free since few weeks.
The tectiles from samsung are pretty expansive and the application they advice isn't as good as NFC task launcher...especially for the commutator mod (a tag can commut between to list of action..)

How to use the tectiles?

So I want to use the tectile in my car. The setting is simple, I want to tap the tectile and my N2 will change into the drive/car mode.Also I want it to go back to normal mode when I get out of the car, do I need to set up another tectile for that?

The tectiles don't have a switch mode or toggle mode? I know nfc task launcher can make switches & toggles but I'm not sure of the tectiles app

So I'm using NFC Task Launcher and I set it to Drive Mode. And it works. But I noticed the settings will remain the same even when I tap it again. So in other words, I would need 2 tectiles, one to get it to drive mode and another one to get back to normal mode? That would be stupid and a waste.

When you select drive mode, does it give you the option to turn it on, off or toggle?
Edit: I see it does give you the option to toggle it. Select that option when writing to the tag. Should do the trick

im pretty sure you would have to make it 2 separate tiles because 1 tile changes what you want changed and every time you touch that tile, it'll do that until you change it yourself or use a different tile. your phone doesn't stay connected to the tectile, it just reads the comand and executes

If you are using the current version of NFC Task Launcher, you hit the plus to add a new tag.
Select New Tag.
Add Enable Car Dock {Driving Mode?}
Swipe the screen to the left to create a Switch Tag and hit the Add a Task button.
Add the Disable Car Dock. {Driving Mode?}
Save and write.
Now the first time you do it, it will enable and the second time it will disable it.
I just created one to do just that.
If you have trouble, I can do screenshots in more detail.

That's pretty much what I did. I've written 3 tags so far. One for home, one for car, and one for office.
The one for home turns off gps, turns on wifi, sets sound profile to normal, loudest ring tone, enables auto-sync, and sets the brightness down to 20%. It also disables the lockscreen because frankly I don't need the lockscreen around the house.
The one in the car turns off wifi, turns on BT, turns on GPS, disables auto-sync, turns brightness up to 80%, sound profile normal, loudest ring volume.
And the one in the office turns off wifi, turns off BT, turns off GPS, disables auto-sync, brightness to 20%, sound profile vibrate.
This thing is just super fun. I have to think of more places I can put these tags on. I'm thinking of putting one in the bathroom to automatically turn on npr in the morning.

With NFC Task Launcher, there is "two tasks" so you can set 2 tasks with one tag. It's exactly what I wanted!
So I just set one for the office where: 1st Task: Ringtone and Notification goes to vibrate only. 2nd Task: Ringtone & Notification goes to level 5. So when I get into the office, I would tap it once and it will go into office mode, then when I leave the office, I tap it again and it will go into the "2nd Task"!
Also found out that you cannot use NFC while the screen is off! That's stupid. So I searched and found this but reading it tells me that it does not work for the N2.

NFC proximity app?

Is there an NFC tag writer that will allow a tag to work in proximity? What I'm looking to do is to mount a peel and stick tag to my car's windshield mount. Then when the phone is in the mount, it will trigger the tasks I've programmed. When i remove the phone from the mount, I'd like the phone to toggle back to the way it was before it was placed into the mount.
I thought i had an app a while ago that would allow this, but i can no longer find it.

I personally haven't tried it, but I did a quick search in the play store for " tasker nfc" and this sounds like it may do the trick for you:

I have that app and i don't see a proximity setting. BTW, that app allows you to set what i would call macros on your phone. Unlike other NFC apps that write directly to the tag, this one stores the tag's ID on your phone, and then you associate a bunch of commands with that tag ID. So when the phone "sees" the tag, it then executes the stored commands that were stored on the phone, without anything having to be stored on the tag itself.

Oh, I see what you mean. I hadn't understood what you meant by the "proximity setting" (I've never used NFC tags). Just to be clear, is the difference in that the profile is changed depending on whether the tag is either in contact or not, i.e. car mode when in contact and then detects the loss of connection when removed and restores to previous profile?
Again, I'm not sure if this helps, but I found this thread from a GS3 forum:

Yeah, I saw that when I searched. That is basically what I'm looking for. The thing is, I could have sworn that at one point I had an app that had proximity built in as standard. Maybe it was just for rooted phones, I don't remember...
I hadn't actually used it back then for proximity, but I thought it was there to be used.
To answer your question, Yes! With proximity, you could set your phone for the normal day to day operation. Then for example, at bed time, you could place your phone into a charging dock that has a peel and stick NFC tag on it's face, and when the phone gets near enough, the tag would activate the tasks you have programmed into the tag. For example, you could turn off WiFi, turn off the ringer, Turn the brightness down to minimum, set a wake alarm/volume/tone, etc... Then, in the morning, when you remove the phone from the dock and it loses proximity with the NFC tag, the tasks will revert to their "daytime" mode, and the brightness will come back up, the WiFi will turn back on, etc...
I realize that all of this can be done by setting the tag to "toggle" functions in that the first swipe of the tag could turn WiFi off, and the next swipe of the same tag would turn it back off, but obviously I don't want to "toggle" by using multiple swipes. I want proximity. (another way would be to use two separate tags near each other and one would be the daytime tag and the other would be for nighttime...)
for the car, I want to turn brightness down a bit (I do most of my driving at night), turn on bluetooth (to sync with my handsfree device), turn WiFi off while driving, start my music app and play a specific playlist, turn the volume up to max (my cassette adapter has very low volume, and the phone automatically lowers the volume when the headphone jack is plugged in), and announce each thing as it is happening (yes that's currently an option)....

Thanks for posting your helpful and insightful comments. They truly add to this thread!!
Anyone else have any thoughts as to whether or not an app exists that allows NFC to work with a proximity setting?

Might this help you?
I understand that what you're probably looking for is an app to "program the NFC tag" itself but I hope you find this helpful until you find what you are looking for.
You can try using an app like Llama (the location aware Brazilian camel ...) to set different profiles (with settings and all) for home, work, CAR,etc. Have Llama identify the Areas first (Don't worry about car at this point just tweak the settings for the car profile). In the events tap you can define a condition (NFC tag detected) to an action (activate profile A: Car).
For when you arrive to your destination and want your phone settings to change to suite your new location i.e. activate a different profile, you can create an event -also in the events tab- triggered when the condition (Enter/In Area)is met. Llama will then alter your settings to the ones you have set for the new area you arrived to i.e. change Car profile to Home or Work. The reason why you have to create another event to change profiles after you get out of the car, after NFC tag disconnected, is that Llama can't detect when a certain NFC tag is disconnected -my understanding- so you have to create a new trigger to bring about a new event.
Keep us informed of your progress as I am really interested in Automation myself. Cheers.

V30 [US998] - Mirror display using Mirrorlink

Thanks to the work by a lot of people in @Moriatier 's "Frankenstein Phone" thread, over here, many of us have been able to flash our V30's from other variants to the US998 variant. An unexpected discovery (for me at least) was that the US998 has Mirrorlink which is not present in at least some of the other variants.
What is Mirrorlink?
It is an interface designed to allow a cell phone to interact with a car head unit. It is similar in purpose to Android Auto (AA) or Apple Carplay (ACP). Basically, your V30 display is shown on your car touch screen and you can control the apps from there. BUT... in the interests of safety, there are MANY restrictions placed on what is displayed and what you can do, as well as steps to limit what you can do with your device while it is connected.
A quick word on safety:
TL;DR - Don't be a jackass. Pay attention to the road while driving.
The restrictions placed on what is displayed and what you can do with those options appear to be there mainly in the interest of driving safety. Texting or other distracted driving contributes to motor vehicle collisions. The purpose of this thread is not to promote playing angry birds while driving.
With that said, IMHO some of - EG in AA, even a passenger is blocked from seeing the full list of music genres available in spotify. I would prefer you give me a warning which i acknowledge, and then let me proceed. IMHO, driving safety is the responsibility of the driver; if someone is going to be a jerk and text while driving, then restrictions on these interfaces are not going to stop that. Just as I would ask anyone behind the wheel of a car, be responsible.
Moving on:
I have used Android Auto for the last couple years, but continue to experience frustration with the limitations placed on the device while connected, and with software bugs that IMHO leave AA feeling like a Beta stage app.
Ideally, I would like to be able to simply mirror my device screen on the car head unit. I could then choose the apps that I want to use. For example, I would love to be able to open the Gasbuddy app and see a list of the surrounding gas prices and link to navigation for the one I choose. I would like to be able to play Ingress without disconnecting and reconnecting the device every time I stop at a portal. I would like to use Google Maps but have access to streetview so I can actually see what I'm looking for. When I pull up to the drive through, I would like to be able to see the list of coffee orders that I need to ask for without having to disconnect my phone from the car. How about when you arrive to pick up someone, being able to read email, news or watch a video clip on your car screen while you wait for your passenger to come to the car!
You get the point. AA and ACP are very restrictive and do not allow this. However, whether by design or error, Mirrorlink seems much more permissive. It even has a "home screen" button to show the home screen on your device. There are several Youtube videos showing Samsung Galaxy S8 users having full access to their phone. Unfortunately, it isn't working as hoped on the V30... yet!
UPDATE: I have a fairly stable setup working now with my V30 on my 2016 VW GTI. Note: I purchased a tool that allowed me to unlock a feature in my car that was blocking mirrorlink once the car was set in motion.

Installation and setup (Post #3)

Links:
LG Mirrordrive App
Button Savior - Non Root
Full Mirror for Mirrorlink
Android Auto App
Screen Rotation Control
Nova Launcher
Screen Resizer
Drivemode

Requirements:
1. A car head unit that has Mirrorlink! Mine is a 16 VW GTI
2. US998, with Oreo 8.0.0
3. Install LG Mirrordrive App
4. Install a Home Screen Launcher that allows for landscape home screens. I am using Nova Launcher.
5. ** I needed to unlock "Mirrorlink in Motion" and "Video in Motion" on my car ECM **
Optional:
1. Install a driving interface app to make launching and controlling your options while on the move safe and convenient. I am usimg Drivemode right now. It is a little cartoonist for my taste but it works well and is easy to use.
2. Install Button Savior - Non Root (So far I haven't seen the need for the root version). This app creates an overlay with customizable buttons to control functions on the phone such as closing a window, or returning to the home screen as well as shortcuts such as opening the dialer app. My car head unit has it's own overlay buttons that are doing the job for now, so I don't need this app, although it might add some functionality. You can decide if you need it or not for your setup.
3. Install Screen Rotation Control - As long as your phone desktop is in landscape mode, you should not need this for typical operation. However, Apps that are portrait orientation only (Starbucks coffee for example) will cause an issue. If you use this utility, it will force even those apps to landscape.
4. Install Screen Resized (or similar tool). On the VW Gti screen, a slim part of the left edge of the image is off the display. This means you can't see a bit and can't touch icons on the left edge. Screen resizer allows you to padd the left edge so it fits properly on my head unit. YMMV
Setup:
1. OPTIONAL: Launch Screen Rotation Control and set it to landscape.
2. In your phone settings under Mirrorlink, tap for options, and select "Allow car to auto-connect." Strictly speaking, you don't have to do this, but if you don't, then you will have to go into the phone Mirrorlink settings each time you connect to turn it on.
3. OPTIONAL: Launch Button Savior - You will need to turn on an accessibility setting - It will tell you. I suggest setting the location of the side button (that you use to open the bar) to the bottom of the screen.
4. OPTIONAL: Launch Screen Resizer - For my VW GTI, I enter 150 (or so) in the top field to make the display fit properly. Then Resize, accept. You can now Close this app. To return to proper size when you disconnect, either reboot or launch resizer again, leave the fields as 0 and click resize and accept.
5. OPTIONAL: Launch Drivemode (or other driving interface)
6 (a). Set you car head unit to use Mirrorlink. Plug in your device to your car and make sure the car is detects it and initiates a Mirrorlink connection.
It might tell you there is no working app on the car, but show the Mirrorlink screen on the phone. In this case, go to the options menu in Mirrorlink on the car and launch the LG Mirrordrive App. Close the LG Mirrordrive app.
6(b) Now go into the options menu in Mirrorlink on the car, and select the option to close apps and close the Mirrordrive App. (Yes, I know you just opened it. We need to open it to get the service activated, but leaving it open may interfere with what we want to do. Hopefully down the road, someone smarter than me can find a way to bypass this.)
7. Select the home screen button in the car menu ( looks like a phone rotating from portrait to landscape on my car unit menu).
You should now be looking at a landscape view of your cell phone home screen!
Working:
I have tested Google Maps, Waze, Telegram messenger, Starbucks App, Gasbuddy and Spotify, to name a few and they are all working!
Of course, Google Assistant continues to be of great help in allowing voice commands while driving, such as, "Send Message to Dave on Telegram" or "Navigate to 123 Wentworth Street"
Problems:
As soon as I put the car in motion, my screen blacked out with a notice saying the app is not available while the vehicle is in motion. I was able to get past this by umlocking "Mirrorlink in Motion" and "Video in Motion" on my VW GTI's ECM. You will need to test and assess your own vehicle head unit. I used an OBDeleven to unlock mine.
I tested Full Mirror for Mirrorlink but had more problems than success. However, this was before finding a work-around for the rotation problems. This might be worth a second look, especially if you are having problems with the car head unit buttons to control your apps.
I tested Auto+ Show, but had no success; it never detected any connection. I think this app might be for a specific piece of video hardware or something.
I get an error on Spotify saying music cannot be played while using Mirrorlink. It pauses the music. I was able to work around this by launching the Rocksound app AFTER everything else is already working. Then I used the head unit on screen controls to get back to my own desktop and Spotify worked properly then.

I'm not sure what you mean? There are some work around (bugs?) Discovered already and hopefully more to be found.

Yes, but just saying that won't help anyone who doesn't already know about that. Please share links and/or your knowledge in that area so others can benefit!

A solution without changing the car's coding would be much better. Especially as this is often removed after servicing at VW/SEAT/SKODA dealership, and it is not possible to do on ANY mirrorlink car.
Currently the only working and consistent (100%) and easy-to-do "hack" consists of using any "drive-enabled" app, and render a floating window (can also be maximized) on top of it. For this Android 7.0 or higher. is MANDATORY. But then you will indeed get full mirroring quite easy.

"using any drive enabled app"
I'm assuming we would all be starting with the LG MirrorDrive app. Does that count as a drive enabled app or do you mean something in addition to that? I recall having to install a mirrorlink enabled music app, open it then cancel it, before launching Spotify, or Spotify audio would be cut off.
"render a floating window"
I have previously enabled the force resizeable option to allow any app to split screen. That appears to be a step being able to launch a floating window according to this:
https://www.xda-developers.com/andr...what-it-is-and-how-developers-can-utilize-it/
Is that what you mean or do you have a different process?

The LG app is drive enabled yes, but you can also use some others, like Sygic or Rockscout. (if you look at the mirrorlink applauncher screen those apps will not have a crossed steering wheel, means they will not kick you out if you start moving the car)
Now with 7.0 as you said, you can make floating windows, as long as the floating window is rendered on top of a drive-enabled app it will work. However right now to do this it would require a bunch of different apps, so the process is very cumbersome. I'm trying to improve this with a single new apk install which brings all the needed features to do this. (e.g. a soft-button bar, a launcher for launching a floating app, maximized on top of it)
There could be several other theoretical options available. (Just theories, i'm still trying to understand how mirrorlink exactly works)
1.) somehow fake the certificate or modify a existing apk to show a different activity than the intended one
2.) somehow make mirrorlink think an app is drive enabled without faking the certificate, instead just add mirrorlink compatibility into the manifest to show up on the launcher
3.) intercept the mirrorlink VNC server / proxy it to a custom VNC server
4.) find a way to let the mirrorlink system think the car is not moving, while it is (without messing with car ECU obviously)
I'm pretty sure MirrorLink has some other weak points, and being a system which will no longer be developed or used (many abandoned it e.g. VW, SEAT is no longer providing mirrorlink app but the moved to AA). So once this weak spot is found, its kinda the holy grail, as this will probably never be changed again (whereas Android-Auto weak-spots might be patched ASAP).
