Samsung S4

Samsung Galaxy S4 on 4.2.2 Rooted, no fancy changes and close to stock as can be. I use Selinux Mode Changer to change to Permissive and I use screen standby which makes my phone reboot after I disconnect it from HU but I can live with that and lastly I use samsung allshare cast dongle thingy. Otherwise all is well for me using ARU, touches work ect ect. hope this helps Samsung S4 users.
[Android General] FPSNEAL:
As Area51 said you should be able to run a few basic commands and correct the problem because knox isn't allowing the app to perform system level touch commands.

su

pm disable com.sec.knox.seandroid

setenforce 0

Those commands will work, but need to be done every reboot. I found that if you just use smanager, make a script using the last 2 commands, then set the script to run as root and also run at boot up it works fine. For your own verification if you open a terminal window through any root app and run 'getenforce' it should say "permissive" if everything worked properly. If it says "Enforced" something was done wrong and it still won't accept the touch commands from the HU.
[Android General] Area51©:
It should be:

setenforce 0

just in case anybody trying this finds it's not working.

does it work for samsung note 3 n900t? because i have tried everything from adding kernels, roms or the commands to kill knox, but they wont let me do it. i think my bootloader is locked. is there any way to unlock it? thanks.
[Android General] brainiak4431:
If you're able to flash a custom rom or recovery, I don't think your bootloader is locked. I'm sure there is a way to unlock your bootloader, just check on the Note 3 forums to root your phone.

Hi

i use a galaxy s4 zoom sm-c105 and all working good but i have just a little problem with screen standby it dont turn really fully black, it just turn with dimmer luminosity down

Any ideas please ?

thx
[Android General] cartisdm:
Well, I ended up downgrading to Slim Bean 4.3 and ARU is back to perfect. Weird it doesn't like KitKat for some reason. It works though and I'm happy!

(Seriously though...if anyone finds a solution to the phone getting so hot, please share!!!)
[Android General] dutchschultz:
So let's say I want to wire a stick into my glove box so I can change it or pull it out when I need to, so is anyone using it with an HDMI extension cord? And the power cord from USB.

Any issues with that?
[Android General] Yarzospatflute:
I have mine in the glove compartment, no problem. The HDMI and USB cable both connect to the Slimport in the box. The only time I've had a problem was when the temp rose to around 100 F, I got a high-temp warning. I opened the glove box and left it open and the phone cooled back down.
[Android General] basmand:
Yes we need a solution to the phone getting so hot, normally I am on HDMI stick, but for the last week I have been playing /using my phone and atleast 2 or 3 times phone has closed down due to overheating!! Never noted that with stick, and as I cant get screen standby to work, it is probably back to stick!!

Basmand :confused:
[Android General] 400ixl:
My phone sits in the arm rest cubby. Never had it shut down once, gets warm, but not too hot.

Mind you, I am using Franco's kernel and have the temperature guard set. Basically it clocks back the CPU's to stop it going over a temperature I set and I haven't noticed a performance issue when it does so.
[Android General] AgentJz:
What temp do you have set?
[Android General] 400ixl:
50 degrees centigrade

Its rarely running on all cores when on the AppRadio. Slimport also seems to create less heat than MHL as well from what I have seen with phones I have had attached to mine..
[Android General] lysaer:
First of all just want to say thank you to the Dev for working on this app.

I recently purchased a pioneer avh-8600bt and am attempting to use appradio unchained with it and my Samsung tabpro 8.4 LTE kitkat.

The tablet connects and when I hit apps on the radio I can see the grey appradio app screen with the white dot, if I click on the screen I get a communication retry error.

If I hit home on my tablet it takes me to the home screen and I can see it mirrored on my radio, but I cannot interact with the tablet via the radio, touching the radio screen does nothing.

I have BT connected, an official Samsung MHL cable and a decent lindy hdmi cable, I also have the pioneer car keyboard installed.

Am I missing a trick here or is this just a compatibility issue with the tabpro

Thank you in advance
[Android General] Area51©:
Did you set the bluetooth connection setting to Others?

If you can do the calibration (hitting 4 white dots) and lose touch after that you have run into a Samsung issue. Besides root, you also need to disable Knox security and set SELinux into permissive mode.

There's no need to install the Pioneer car keyboard for ARU.
[Android General] lysaer:
I will go try what you have suggested, thanks for the hard work and fast response
[Android General] oderuyter:
I want to second this - same issue - finally over the moon it works better (never had it working) but using Note3 + ARU + AR3 I can see, and interact during calibration, however after that, I cannot control the device,through the AR3 - Would really appreciate some help

THANKS DEV - YOU ROCK!!
[Android General] Area51©:
It's this issue for Samsung devices: Besides root, you also need to disable Knox security and set SELinux into permissive mode. Easiest way is probably to find a custom kernel that has this set by default. Best to do a search in this thread as there is no universal solution due to quite some different sw versions for various providers.
[Android General] dutchschultz:
Oh you're using a phone hey, you may have better luck with an HDMI stick

That's what I want to use, but I'd need to use and extension cable male to female I guess like 3 ft for good measure

Anyone else try this?

gps injector not working

HI, ive just purchased the gps injector app and just gone through the steps to try and get it going,

heres my setup,

galaxy s5 running near stock rom with custom kernel to remove seandroid

appradio 2

after the final install of the injector i restarted the phone and it come up with android upgrading? is this correct?

once connected to the head unit i turn my phones gps off, and with google maps try and get a position fix which never happens, i open up gps inject which shows it has a fix of longtitude latitude etc and the service is running, whats the next step?

cheers
[Android General] brainiak4431:
I think you have to move it to system, priv-app on Kitkat in order for it to be able to automatically turn on and off the mock locations. Besides that it seems like it will work.
[Android General] tragictramp:
yes i done all that, thanks.
[Android General] tragictramp:
Atached is a screenshot showing whats going on, the gps is working and getting it from the head unit but not transferring it to google maps etc
[Android General] 400ixl:
Isn't that another of the Samsung "features", or known bugs to the rest of us?

Came in with their 4.4.x implementation of Android.
[Android General] texbuck:
It seems I've read about this somewhere. Be sure that it's high quality with extra shielding because there is tons more electrical noise in a car than in a house.
[Android General] Area51©:
Everything looks fine. You are getting GPS data and the Status is Connected, which means that it's injecting using mock locations. To verify can you install an app called GPS Status and send a screendump of that?
[Android General] tragictramp:
Yes attached is gps status a shot of appradios connection status, whats strange is that even with gps off on the phone when I walked back in gps status is grabbing a gps signal off the phone even though its switched off, waze and navfree also gt a gps lock off the phone even tho its switched off on the phone.

Cheers for the help
[Android General] Area51©:
It's working. The Number of sats and DOP/HDOP/VDOP is not shown, which means that it's using the Injector GPS data. If you would try without being connected to your HU and the phone GPS it would show Number of sats and DOP/HDOP/VDOP.

Now that you say you switched off the phone's GPS, I remember that Google Maps doesn't work in some cases when the phone's GPS is switched off. I think you have to keep it switched on for Gmaps to know there's GPS data available. However the HU GPS data will still be used as Mock locations has the highest priority. There's also another issue with Gmaps and that is when you are just showing the map an driving around it will use the orientation of the magnetic sensor of the phone. So depending on how your phone is oriented in your car. When you use navigation in Gmaps the bearing as injected from the HU will be used, thus showing the correct heading.
[Android General] bk73w:
When you turn on the radio make sure BT is on first don't connect mhl cord until you see connected "not ready to connect" in your status bat (usually takes 10-15 seconds) then connect the mhl cord
[Android General] Wiltron:
Hello all - could use a hand if you wouldn't mind. I went through all the suggestions listed here, but none worked. Here's the facts:

SPH-DA110 (AppRadio 3)

Parking Brake Bypass Switch Installed/Working

CANBus Bypass (For Chrysler vehicles) Installed/Working

Sony Xperia Z1 - Latest 4.4.2 STOCK rom, Rooted, Locked Bootloader (Everything is stock, even the launcher!)

Pioneer CD-AH200C Android MHL Adapter

Sony MHL / HDMI Cable

Here's what's going on, in detail. I've numbered the problems for easier replies if you're only able to give some advice on one :)

1. The Bluetooth Phone Audio

AppRadio boots up, connects to bluetooth. Voice command is partially working. It hears me speak, the Google Voice microphone icon when it's "listening" is moving, and is doing stuff (ex. "Call XDA"...... "Calling XDA.."), but no audio is heard from this. PLEASE NOTE: Bluetooth Streaming audio from Google Play Music works fine. This is strictly phone audio for some reason. When connected to two different head units, phone audio works fine.

2. The Black Screen Problem

ARU and AR apps (the non-unlocked version) both install fine. After BT connection, the android man lights up and I can click the Apps icon. MHL Mode activates on my phone, screen rotation locks to landscape, and I load up ARU (or AR). The calibration screen appears on the device. No calibration screen appears on the head unit. Touch response is fine on head unit, as I can estimate where it wants me to press the white circles, and it passes. The ARU or AR screen now loads my contacts, maps, etc. I can swipe across the head unit and stuff "happens" on my Z1. Buttons on the HU do "stuff" to my Z1. The Headunit is black (not off entirely, it's displaying the greyish/black "background").

Things I've tried to fix the black screen problem:

Swap HDMI Cables

Use Sony MHL Adapter instead of Pioneer MHL cable kit

Double press HOME button on HU (pulls up the bar on the screen)

Disconnect, reconnect BT (this includes un-pair and re-pair)

Disconnect, reconnect HU

Confirm MHL Cables are working on my Samsung 42" LCD TV (Yes they are)

Factory Reset HU

All of the above didn't work.

Mirroring of my laptop using an HDMI cable mirrored fine without issue. I know the head unit is working fine. This is the last piece of the puzzle for me. I can't figure out what's going on, why I get no video on my headunit. All I want to do is mirror my Z1 on the AppRadio3 so I can control it like it was a tablet in my dash (that plays the audio, uses Google Maps as Nav, Uses phone search and all that, etc).

If you require more info, have questions, please let me know. Please post here so others can find solutions if we figure it out.
[Android General] ikerg:
First of all ensure you don't have any defective ar3 unit.

Try with any other HDMI device if the ar3 can mirror it (laptop or even a bluray)

[Android General] Area51©:
Good suggestion. The Apps icon will light up with any valid HDMI input, you can display it by hitting Ignore for the bluetooth connection.
[Android General] shaxs:
I did a quick search but I wanted to ask after not finding what I need.

I have the GPS injector working..but I cannot figure out how to get mock locations to automatically put on and off. Im on 4.4.2 kit kat.
[Android General] 400ixl:
Have you made it a system app in the correct folder?
[Android General] shaxs:
Yep! It is in priv-app following the directions in the FAQ
[Android General] Area51©:
If you force close the GPS Injector and then manually disable Mock locations in the developer options, does it work after that?

If Mock locations was enabled already, the GPS Injector won't touch it, assuming it was enabled already for a reason.
[Android General] mannyhernz:
OK so just got an s4 and an app radio 2... can I stay stock rooted and install aru? I'm on 4.4.2
[Android General] 400ixl:
Only if you can reset the SELinux permission every time you boot You will probably also be best off using a custom launcher such as Nova or Apex.

Better to have a custom kernel with SELinux set to permissive, provided you have an unlocked boot loader.
[Android General] mannyhernz:
I have Nova. . But not quite sure on how to reset the selinux...I have already been able to connect calibrate screen. . Then it goes through the pioneer splash. . After that I get my screen but no touch. . What did I do wrong?

Is their any reason certain apps dont like to be mirrored?, i use torque for diagnostics on my car and tom tom uk, but both wont mirror properly to the head unit, they both go black and randomly flash on and off, every other app is fine and the display on the phone is correct at the same time, ive used 2 different mhl adaptors which reproduce the same problem.

cheers Area51 for helping me get gpsinject working, good work.

[Android General] Area51©:
It' very likely to be an issue with your MHL adapter. Cheap generic adapters don't have proper shielding. Especially for a Samsung device you should get a genuine one from a reputable place so you know it's genuine as there are a lot of fakes. Also get a good quality HDMI cable, possibly with ferrite cores.
[Android General] Emporioo:
Was just coming back to this thread to post this very same problem I'm having. Torque worked perfectly on my s4 when mirrored but now I have got an s5 it flickers on the torque app making it unusable when mirrored. I also tested another obdlink based app and the same problem happened...

Are you using AEL kernel by any chance? I have noticed there is now another kernel called blaze and it would be interesting to see if that clears the problem, I'll give it a go later on today
[Android General] tragictramp:
yes mate ael kernel to get rid of seenforced nonsense, got a link to the blaze kernel?

[Android General] tragictramp:
tried and exactly the same, tried tom tom on my tv and that mirrors fine, obviously cant try torque due to distance from car.

So i dont believe its an mhl issue and maybe kernel or something sammy have meddled with.
[Android General] Wiltron:
Plugged the very laptop I'm typing this on right now into the HDMI (using a direct connection; not the MHL cable) and it worked fine. Mirrored with audio over factory speakers and everything.

Starting to think it has something to do with the phone..

I'm rooted, permissions given to ARU. I have touch input on the head unit, and stuff is visible on the phone. It's not the SELinux but that's going on (to the best of my knowledge).
[Android General] bigcid10:
torque mirrors fine on my htc one M8
[Android General] Emporioo:
Well that sucks.... Really miss not having the obdlink features/gauges mirrored
[Android General] Area51©:
It's not the SELinux issue, that will result in no touch from the HU but not in a black screen.

Your issue must be something with the generated HDMI signal being slightly incompatible somehow.

As you said:

A) Phone -> MHL-adapter -> TV, is working

B) Laptop -> HU, is working

C) Phone -> MHL-adapter -> HU, is not working

It could still be:

A) Phone

B) MHL-adapter

C) HU

D) HDMI cable

Quite a difficult issue. Maybe the phone is not 100% compatible with the MHL adapter?

What if you disable Bluetooth on your phone, then connect it to your HU and ignore the bluetooth connection?
[Android General] Wiltron:
The main man himself replies :)

Any idea where I can start the debugging process? Logs would be useless to you at this point I would assume, but I'd be happy to provide.

If my phone was broken or something, I wouldn't have been able to use the Pioneer MHL Adapter on my TV and see my phones screen without issue.

If my cables were broken, I wouldn't see any video on the HU or TV regardless of which device is plugged in.

But the counteract to my thinking here now is that if the HU was broken, my laptop wouldn't have shown on the screen..
[Android General] Area51©:
Just added something to my previous post.

I was going to suggest to swap the MHL adapter or the HDMI cable, but you did that already.

So it's either the phone or the HU.

You can try your HU with another phone.

Try your phone + MHL adapters with another HU. Can't you do that at some shop?

What about the power supply, what are you using to power your MHL adapter/phone?
[Android General] Wiltron:
The only car audio place in my city is closed Sunday/Monday :(

I have only a Nexus 4 at my disposal, which doesn't support MHL, and an iPhone 4S which I don't have the cables for.

Power supply was tried from the back of the unit, as well as I have a charger connected to a plug (inverter) and cable. No dice to either.

EDIT: Here's the result of the MHL Connected no Bluetooth request:
[Android General] Area51©:
Yeah, it was a long shot. Let me check from the survey if anyone else reported your phone working.

Someone reported a Sony Z1 working with an AR2, Stock Android and an unspecified MHL adapter. So it can work.

Another thing to check maybe, does your AR3 have the latest firmware? If not, an update might help.
[Android General] Wiltron:
I'm on the latest firmware for the AR3, and for my Z1.

I don't know what else to try - I am open to suggestions. As you see in the above picture, I've ripped apart my entire dash (required to replace headunit) so I'm willing to try just about anything. I have 26 days left to return all this stuff for a full refund..
[Android General] ice_coffee:
I am fairly confident that the Torque app is for some reason changing the resolution output from your HDMI. The app radio will only accept 720P @ 60 Hz, nothing else works or rather nothing else works properly because after testing I also found that 480p @60 Hz works but flickers like crazy. I guess if you were to test this you would have to plug it into your tv and get your TV to tell you what signal it is currently receiving (not all TV's do this but the better ones do) then start up the Torque app and see if the resolution changes !
[Android General] Area51©:
I think you may be mixing up a few things. Wiltron doesn't have issues with Torque. Also that the HU does only accepts 720P from your HDMI stick doesn't mean that it won't accept other resolutions from other devices. I know it does actually accept other resolutions than 720P.
[Android General] Area51©:
It's a tough one. It still may be your HU. I think that the laptop HDMI signal and the phone's don't have the same resolution so that may be why one does work and the other doesn't. The HU accepts the HDMI signal as valid (or else the Apps icon wouldn't become active) but refuses to show it on screen. My best bet would be to try your phone and HDMI adapters with another AR3.
[Android General] Wiltron:
I have an old ZL at work that's currently modded to **** (custom rom, kernel, etc.). I'll restore to factory tomorrow and try the setup with it, as the ZL is directly listed as "compatible" on Pioneer's website. If it works, we know for certain it's the Z1 that's the problem. If it doesn't, well, we're up **** creek again :P
[Android General] ice_coffee:
If you don't mind my asking, what other resolutions do you think it is capable of ?
[Android General] bigcid10:
the M8 doesn't need to worry about selinux .the issue with the M8 is

it has to be s-off and rooted .s-on isn't good enough

my M8 was rooted and s-on still no touch.in fact a lot of root only apps didn't

work either.busybox was one of them.until I went s-off nothing worked right

and when your s-off ,now you can flash a fast charge kernel

like ElementalX to help with charging
[Android General] DiGi91:
Seems like it's happening with the original app too, not sure why.. also could the injector not be working because this phone is out of service? *shrug*
[Android General] shaxs:
Ah let me try that. I had manually enabled it.

---------- Post added at 12:20 AM ---------- Previous post was at 12:17 AM ----------

What are some other options to minimize battery drain when using this? I am running a LG G2 which uses a slimport adapter. I have done the following:

1) Use tasker to set wifi off

2) Use tasker to run Screen standby which turns off the backlight

3) Bought the GPS injector to use the head unit gps

4) Plugged slimport into usb to get "slow charge" as reported by phone.

Do I need a kernel that does a fast charge?
[Android General] bcs2112:
Could you detail me how do you use the Screen standby ... i've tried both of Screen StandBy (older and newer version also) apps, but without succes (bit offtopic area here, but maybe it can relevant for others too). A can turn off the backlight, but in this case the hdmi screen also is dimmed out...

AVH-X8500BT Galaxy S4

Hi Everyone,

Apologies if someone has already asked/answered this, but I've just ordered a Pioneer AVH-X8500BT and want to get it working with my Galaxy S4 GT-I9505 currently running stock version of KitKat 4.4.2.

What connectors do I need to connect the phone to the head unit? Do I need the Pioneer CD-AH200 MHL adaptor kit, a Samsung ET-H10FAU MHL adaptor, or can I use a cheap eBay cable (I can't post links yet, but the item number is 141034620923)? The eBay cable looks ideal because it's nice and long, without multiple connections/boxes etc, but I'm not sure it will work.

My only other query relates to rooting my S4... Does anyone have any recommendations as to what ROM is good/compatible with AR Unchained? I'm not after anything vastly different to the stock KitKat ROM.

Thanks

Simon
[Android General] mannyhernz:
I have just recently done this..

Buy only samsung mhl..

Returned 2 that were not samsung

I am also running stock 4.4.2 rooted.

There is also a fix a couple of pages back that worked for me, using the fix along with tasker with no issues.
[Android General] simonrob77:
How do you get on having the "Box" with it's connections loose in the car? The cable from the adaptor to the phone isn't very long, so hiding it away isn't really an option is it?
