Hello to all,

having brought my s7 edge in assistance now I find myself with another problem. The front camera is not working, but when I go to the hardware menu check * # 0 * # work, so when I enter the camera app from the app or any other app only works the back room and when I make a change to make "selfie" not work out the message "camera error" ...

For now I tried:

1. I deleted the cache and data of the app Room

2. hard reset with a full wipe

3. I initialized the phone with samsung reinstalling switch all over again

what else could I do? I have to return it to service?

Thank you

I thought it would be better if we consolidated all the discussion on the PX5 head units into a single thread and I will try my best to group all the useful information in the first few posts when more information becomes available. I think this will help with discussion on these head units and help improve everyone's experience

Post 2: Firmware

Post 3: Tips, Tricks and Fixes - Rooting instruction here

Post 4: Bugs/Issues

Post 5: Useful apps

Post 6: Useful links

For those not familiar with the PX5 Head unit, the specs are below:

OS: Android 6.0 Marshmallow

CPU: Rockchip PX5 A53 Octa-Core

RAM: 2GB DDR3

ROM: 32GB

Audio output: 4*45W

Features:

Built-in Radio Tuner (RDS Enabled) (18 FM and 12 AM stations Preset)

Built-in USB & SD Slot

Region Free DVD Player

Screen Mirroring

Steering wheel controls (SWC) and Canbus interface

Optional compatible accessories:

DAB+ USB Tuner

TPMS

4G/3G Dongle

OBD02 Module

Camera

DVR

External Mic

The head unit comprises of two parts:

a MicroController Unit(MCU) board, which controls physical buttons and A/V inputs/outputs to/from the headunit. This board interacts with Android OS.

ANDROID part. The main Operating System.

Both MCU and Android ROM interact together to achieve the functionality of the head unit.

Manufacturers/reseller:

GS - XTRONS

HA - HotAudio/Dasaita

KGL - Erisins

MX - Witson

LM - Erisins/Pumpkin

A comparison between PX3 and PX5 can be found posted here by [MENTION=5429956]FauxDreams[/MENTION] with some previous discussion on PX5 in that thread as well:

PX3 Vs. PX5 initial impressions, some issues/findings after a day of ownership etc

Some information I found on the CPU:

Rockchip PX5 Press Release
[MTCD Android Head Units General] aarick:
*Warning: Do not install 1024x600 fw on 800x480 HU*

It has been reported that it will not display properly once installed.

An update usually consist of two files:

The Android ROM (update.zip) and it is usually compatible with any head unit of the same model (MTCD) and CPU (PX5).

The MCU (dmcu.img) is specific for each manufacturer and it should never be updated on other manufacturer's MCU update file (unpredicted response from physical buttons - or CAN bus responses, or bricking the unit).

However, it has been tested and confirmed that JY, KD, GD and now HA MCU are cross-compatible Verified cross compatible MCU thread (thanks for info [MENTION=4974080]marchnz[/MENTION](

Update at your own risk!

Installation instruction:

Unzip update.img to the root of the GPS SD Card.

Make sure you Don't include the dmcu.img if your MCU does not match the MCU of the firmware.

Will add more info here as more tips, tricks and fixes shows up.

Rooting:

Rooting has been achieved by using the app Kingoroot. Kingoroot APK

This will root the device and install Superuser app. Internet connection will be required during the root process. As I am not a fan of superuser and kingoroot staying on my device, I change superuser to supersu and uninstalled both app. Please see steps below.

Reported to not work on hotaudio devices. It gets stuck at 10%.

SuperSU:

Install SuperSU (I used SuperSU Pro) from the play store and grant it superuser access. When prompted, install updated su binary with the normal mode. Once installed successfully, uninstall Kingoroot and Superuser app. Reboot.

Screen DPI:

Some apps, does not display properly with the screen DPI set at 240. Spotify for example has the login button missing. I use a DPI changing app to change the DPI to 200 to make Spotify login button reappear. Check the useful app section for the app I use that allows for the DPI to be changed on the fly without a reboot, but DPI can also be changed by modifying the build.prop

https://xdaforums.com/android-auto/...-unit-discussion-thread-t3573881/post72134396

May be a better option as runs within Android and not dependent on MCU manufacturer. You need the following:

- a DAB + stick with an RTL2832 chip e.g.

(http://www.ebay.de/itm/USB2-0-DVB-T...0T-/262943378408?_trksid=p2385738.m2548.l4275)

Developer Options:

Standard 7 tap on build no. does not work on these head unit. To enable Developer Option, install this one:

As bugs/issues are confirm by other members, I'll add to this list.

Bluetooth:

~ Same issue with most other MTCD head unit. The bluetooth is not able to communicate with the bluetooth devices besides the official optional accessories, or phones. I tried using my bluetooth TPMS with this and it did not work.

~ Echo during calls also reported. Might be related to both external Mic and internal mic working together.

WiFi:

~ WiFi on these units seems weak and unreliable. Issue seems to be a weak antenna, bad solder and/or no diversity soldered in. Some users have success in soldering diversity and getting better reception. Disabling bluetooth also helps as bluetooth usually use the same 2.4gHz chip and will reduce interference when disabled. A more powerful antenna also seems to help some.
[MTCD Android Head Units General] aarick:
Useful Apps:

Easy DPI Changer - This apps seems to allow for DPI changes to be made on the fly without reboot. I am not sure if this is because Marshmallow supports this or if the app does anything different. Have not tried other DPI app.

FM Radio Controller - Control FM radio from notifications and more features.

AnyAutoAndio - Allows more app to be controlled within Android Auto App, including FM Radio Controller above

Android Auto - Google's head unit interface/launcher

MTCD Tools - Allows you to customise all your buttons to launch custom apps or do custom actions

Just had the Xtrons PX5 unit for around 3 days now and I am enjoying it. I originally had the MTCD RK3188 1GB unit that was slow and boots extremely slowly.

So far, experience been good. 2 small issues I have notice so far are that my WiFi isn't as strong as the previous unit and the station details aren't coming across to my centre display of my dash with the right info. I might try playing around with some of the factory settings and canbus options to see if it'll resolve it.

Love the fact that the HU doesn't shut down but goes to sleep and comes on instantaneously once I put the ignition key in.

I found out, there are follwing possible passwords on which factory settings has reaction

Static programmed passwords

126 - opens facotry settings app (Device customer name beginns with RM - parameter ro.product.customer).
m123456 - opens facotry settings app with bit other parameters...
adbon - enables ADB
adboff - disables ADB
keject - sets ctr_key to eject
kpower - sets ctr_key to power
hcttouch - display some touch info. probably touch panel area size in pixels
hctreboot - initiates device reboot

hctbtup - writes on screen "BT updata!" , Sends Android Intent
hctbtte + 3 digits - probably starts some tests with bluetooth adapter. but no information what this 3 digits meaning

logcls - clears logcat
logcat - executes logcat as follows [b]logcat -f <filename> -v time
filename = <external storage>/<current date+time>_android.txt
kmsg - excutes dmsg command and writes output to <filename>
filename = <external storage>/<current date+time>_kernel.txt
radio	- executes logcat as follows [b]logcat -b radio -f <filename>
filename = <external storage>/<current date+time>_radio.txt
logcan - starts CAN bus logging app

1199	- enables/disables HZC_MENU . I don't know what it is
v5555	- Enables/disables Video while driving. Enable also removes "Watching video" under Car settings
hcttest + up to 3 digits - not tested yet.

There are also up to 2 passwords, which are stored on device. Action same like with password: 126 . Probably one of them set to 126.

EDIT:

On _GS Device in MCU stored passwords

126 - opens facotry settings app
3333 - opens facotry settings app, only logo change screen

Hey there

i noticed the changelog has a Kernel G sensor... can someone just help me verify if the unit comes with a G sensor/ accelerometer built in? would be fun to have that on with the OBD torque app.
[MTCD Android Head Units General] aarick:
Radio channel to my dash display is working now. Not sure what changes made it work. But I did turn off canbus and turn it back on.

EDIT: Issue comes and goes. Still ongoing.

New issue I found is that I'm not getting sound to the rear speakers. Might be just specific to my unit or model as I have an Audi specific xtrons model. Have emailed the seller. Anyone have similar experience?

Strange thing is that no sounds are coming through the rca cables. Even with all 4 unplugged, the front speakers still producing sound.

EDIT: RESOLVED, didn't realise the speakers are treated as amp and I needed to plug in the amp control cable.

I don't have access to my head unit at the moment, but I remember seeing an option called Default power status or something like that. Maybe that will do what you want?

Yesterday i lost all data on both sd-cards. I think that was already second time. Have someone noticed such problem?

I don't have any G-Sensor. Elixir sees, that there is G-Sensor enabled, but no I don't get any reaction on it.

Probably hardware part is missing. Maybe some of unit versions have this sensor.

If some chip is built in, under "Extra settings" G-Sensor sensitivity setting will be displayed

This option has some other function. HU state while next power up

On - normal boot

Off - boot to standby mode. Display while boot disabled. No info about sound, while my HU still not installed :(

These units wont fully power-down - that's how they are designed.

Some people have reported issues with battery drain, however others (myself included) have had no problems.
[MTCD Android Head Units General] TPXX:
Wire to a switched hot source? If it can't get power, it will shut down. You could also wire a switch into the power line and mount it on your dash somewhere. Flip the switch and no more radio drain.
[MTCD Android Head Units General] Grumpycat62:
It's not that I have any problems. I just have Tasker's run state as "Power - Any" so this unit has made that useless.

Hopefully someone finds another way of doing this, even if this is how these units are designed.
[MTCD Android Head Units General] Peppergrinder:
That's what I did when I received the unit - it constantly draws about 0.5-0.6A when it's shut down and it is cold booting if you shut off power supply. Of course I had to detach the can bus adapter and this probably prevents the unit to go into hibernation.
[MTCD Android Head Units General] TPXX:
The Canbus adapter is for built in radio controls (steering wheel) ? I did not install one, and don't have any built in radio functions in my car.
[MTCD Android Head Units General] Peppergrinder:
For sure the adapter interprets and allows the radio to display certain information provided via can bus like climate control, headlight status, ignition status... and thus it can shut down the unit when you turn off the car. In my case there has to be at least some small current coming from the adapter to keep the unit alive, otherwise it would just do a cold boot as it did when it was plugged in to the power supply.

If you do not connect a can bus adapter I'm pretty sure it is drawing constantly approx 0.5A from the battery and then it is just a matter of time when your car won't start - at least that is how my unit is behaving, and I'm not even sure if it less when the adapter is connected. I have a 110Ah battery and move my car almost every day, so probably after a longer vacation I will find out.
[MTCD Android Head Units General] Bingoboy1975:

Ok, mine got only one. I'm not sure, since my unit is at the tech support, but I think the fakra adaptor has another wire, which in my old unit was for giving more power to the antenna, Is that possible? In case it would be true, where do i connect it to? In my old head unit the wire is blue, in the new one, I'm not sure, also I dont know if there is something at the label attached to the wire.

Some people asking me about dual antenna. Here there are some details.

I removed first stock short antenna in first try and wired then two wide antennas, the one you see is inside front dash panel of my BRZ (near you see TPMS01 module) and another one is inside cluster cover on left. About this one, I removed the antenna's external cover and glued it inside on top cover The signal strength you see is inside my building cover park as far as 100 mts from my home, two walls in front. DO NOT CONSIDER DR650 SIGNAL thus is Blackvue. JPN4 2.4Ghz on Asus DSL-AC68U is my Home network. Signal list is very wide (at least 15 wifi stations). On road the number of station will increase about number and strenght.

Home network on Xtrons:

download up to 80 Mb/s and upload up to 25/30 Mb/s

[MTCD Android Head Units General] Bingoboy1975:
Well done. I've never seen a signal strengh on mine like this before. Without soldering WLAN receiption was impossible with my device. After soldering a pigtail and mounting a big antenna like yours my signal strengh is 2of4 at a distance of 10m :D

Maybe I loose a lot of quality because my wires are to long. Pigtail plus 1.5m sma extension cable and then the 30cm antenna in the A pillar of my car.

I mean upgraded your SoM only, if you have an entirely different unit it will not prove or disprove the theory.
[MTCD Android Head Units General] f1x:
In case of PX5 it is controlled by android native layer. In gocsdk there are usages of AudioTrack and AudioRecord. Communication with bluetooth module is done by usb to serial driver. Gocsdk receives SBC buffer from bluetooth module, decode it to PCM buffer and put to the ring buffer. When 160 bytes of SBC buffer are collected, then buffer is pushed to the AEC. Same for the microphone.

I just use the HU's built in microphone. Just to repeat: HU is Xtrons PB96MTVAPL = GS PX5

BT is using MD725 factory setting

My calls have no echo - for caller or receiver - when the HU is not doing much work. But following the discussion (after your reply to my post) between typos and f1x, I did some simple experiments. Calls have no echo for caller or receiver on landlines or mobiles when apps such as Torque, PowerAmp (fades audio during call), Radio (also fades audio during call), GMail are running. But when I run CoPilot or Sygic satnav apps an echo of the receiver's voice appears for the receiver, but not for the caller.

F1x, your explanation makes some sense to me but the 8 CPUs are running at ~600 MHz most of the time when the SatNav is running. There should be plenty of CPU headroom to keep the SCO latency within range of the AEC. What is making the latency grow so long?
