[question] Android 6 or 7

Hello
Is it possible that we will have android 6 or 7 on ours MTCD units? Or MTCD has only 5.x and its max?

No. They shouldn't even have forced 5.1.1 on the RK3188 chipset, as you can see from all the complaining, its too damn slow.

My thoughts exactly, I am now looking for a 4.4 ROM for MTCD to try

@sterod ok, Im using iOS on phone and dont know android good but newer android like a 6 or 7 dont need less ram and cpu? I think is more optymalized than older.

No. They need more of both. It was a hack to get the rock chip 3188 kernel to run android 5.1.1, it was never meant to and now all of us with slow and laggy MTCD units are feeling the buyers remorse.

No downgrade possible?

Not that I'm aware of. Parts of the board are not compatible between the two versions.

And a good old software downgrade? Like back in the days with Android.
My unit works pretty smooth. It only takes a bit of time to boot. Any boot speed up tips?

That's what I meant, you can't downgrade a MTCD 5.1.1 unit to 4.4.4
Boot speed up can be improved by running the "speed" app in the status bar to disable startup apps

Got a link? Can't seem to find it in the playstore. Or am i looking in the wrong direction?

It's built into the rom. When you are using the head unit, if you pull down the top status bar, you should see an icon called "speed" alongside the others like Amp, etc.

i would definitely be interested in a faster model, but i certainly do not have buyer's remorse over my Joying MTCD with Android 5.1, i love it.

Mike, if you didnt previously own a MTCB 4.4.4 unit (like I did) then you may not know just how bad the MTCD's are in comparison. With 4.4.4 EVERYTHING worked, Bluetooth, super fast GPS, no lag, it was wonderful. MTCD was a huge step backwards.

well that is correct, I did not own a MTCB before, so I have nothing to compare it to

Ignorance is truly bliss! Thankfully these units are cheap and essentially disposable at their price point. MTCD is going to be forgotten as the red headed stepchild that Windows Vista was If I could get my hands on a 10" Joying MTCB unit running 4.4.4 I'd swap mine out immediately.

the mtcd is immature, and slow. I have a 10.3 inch mtcb in my wife's car it works great. I used to have a 6.2 gs in mine. I have a joying 10.1 mtcd in mine now, it works like crap. It is slow, google maps barely opens, gps is for crap if it works at all. If I could put a 4.4.4 board in there I would. Sometimes older is better. Sometime it takes several seconds to even turn up the volume. It is crap.

Sorry if my questions sound stupid or have been asked elsewhere in this forum.
Is it possible to use a custom kernel with the ROM for the MTCB unit?
I am asking because even with having low hardware specs built into the head unit, a talented dev could pimp out the kernel to allow the device run much faster..
Edit: somebody knows whether the RK3066 chipset has similar characteristics with the one of RK3188? Maybe in that case the kernel from RK3066 can be ported to work with a MTCB unit.
Edit2: According to this comparison it doesn't look too bad: http://system-on-a-chip.specout.com/compare/309-310/Rockchip-RK3066-vs-Rockchip-RK3188
P.s.: However, i am not sure about the drivers that are needed to compile the kernel for the head unit. I guess that there is a bunch of proprietary hardware related stuffs that have to be considered.

They have never released any kernel source for MTCB or MTCD as far as I know. So I don't think there is any possibility for a custom kernel. They clearly violate the GPL but they don't care.

At least the kernel source for jelly bean for the RK3066 is available here: http://www.rockchipfirmware.com/sites/default/files/GPL_Edison.tar.gz

Ever tried to make a custom kernel for a Galaxy S5 with just the Qualcomm sources? No chance. You always need the kernel tree from the manufacturer which includes all the bells and whistles to get their crap running.

Android 7 on PX5?

Hi! I wonder if someone has Android 7 running on a PX5... Improvements? is it.worth?
Thanks.in advance

I have been wondering the same, and after searching for hours on this forum, I'm surprised. Is putting Nougat on the Px5 not possible? That seems like a weird limitation. I'm trying to decide what unit to buy, and I can't believe that the choice is between older hardware and newer os, versus newer hardware and older os.

The ability to upgrade is mainly limited by hardware drivers for certain kernel versions.
There are some rumors about Android 8 for PX5. Stay tuned.

Yes, I thought this was weird too. While PX5 board is faster it seems all the OS development is going to PX3. We already now have 7.1.2.
I've also noticed that lots of PX3 boards are now coming with 2GB of RAM as standard. One thinks maybe it was just a RAM issue and manufacturers don't want to make a more expensive board when all they really need to do is an an extra 1GB RAM to existing PX3s.

Has anyone tried the android 7.1 2gb 32gb octo core units yet??

Posted in wrong thread sorry
As title im thinking of buying this unit
http://www.autopumpkin.co.uk/vw-ste...ation-for-vw-skoda-seat-series-octa-core.html
for my octavia vrs and wondered if anyone has opinions on them as they are octo with 7.1??
Or would the android 6.0 4gb! 32gb octo core be better / more stable??????
like this one

cheers

This looks pretty weird to me. The hardware facts (Octo-Core [Big.Little], 2GB RAM and 32GB ROM) sounds like a normal PX5 unit. PX5 however is not available with Android 7. Only Android 6 is available.
The description also says "OS: Android 7.1 Marshmallow" which is kind of wrong since Android 7 is Android N (Nougat), not Marshmallow.
I guess if you order it you will get a PX5 unit with Android 6 on it even if all pictures seem to be indicating Android 7.1.
Alternatively you might get a PX3 unit with Android 7.1 on it. There are PX3 units with 2GB RAM as of my knowledge. But then the Ocata-Core description is wrong. So either of them is wrong or you would get some complete custom design.
Anyway there are rumors that soon there will be Android 8/O/Oreo available for PX5. So I think this is the best way to do. It also seems that the first PX5 units with 4GB RAM are about to appear on the market.

isnt the 2nd link i posted a px5 with 4gb of ram?
If its not true then its best i wait for an oreo version with hopefully 4gb and octo-core fingers crossed, was hoping for it by christmas.

This is true. My reply was more about the first link with technical data which does not seem to comply to PX5 units or are invalid anyaway (Android 7 isn't Marshmallow).
Likely both units are PX5 based. The second one is pretty sure a normal PX5 unit with 4GB RAM.
I also don't believe we will see any issues on 2GB devices on Oreo. Oreo isn't much more demanding regarding CPU and memory resources than Android 6/M. Also I am personally using this device as a head unit (some navigatin, music, streaming, perhaps some video playback) but no real heavy applications which would require more than 2GB of RAM. Of course there are lots of inefficient apps out there but get real, 2GB is quite a lot of memory.
Looking forward to see the first Oreo releases.
Too bad nobody seems to release the code so we would see much more and better custom ROMs.

can you post a link to the unit you have please.
are you having any major issues with it? do you have the dab dongle etc.
my last unit was a 1gb 4.4 unit and it was so bad it went inn the bin as erisin tried a repair and sent it back useless!!!

Well, this won't be very helpful. I currently own a Subaru Levorg and got something like this here. But it's car specific shaping, no standard 2-DIN form factor. Also it didn't really fit my cars connectors so I fixed it by soldering my own cables. But it's a standard PX5 unit from KLD manufacturer.

No Major issues with it, only minor. Not counting the wrong cable harness as this was an issue of my car not being in any supported list.
So I am mainly suffering from standard PX5/ROM limitations. For example Google Maps in latest version hangs if terminated by auto-shutdown. There is a fix available here but it requires root access to clean the cache of another application.
Also my unit has some audible noise level which is noticeable at low volume levels. Not really an issue while driving but still annoying. The noise seems also to be dependent on touchscreen input. It's a sign of inappropriate filtering inside the unit.
My unit also suffered from very bad WLAN reception initially but this was clearly related to the bad antennas mounted to my device. I did a post about my modifications here. In addition I have meanwhile added some good WiFi Antennas directly into the dash center display which further improved reception.
These units are also known to cause slow WiFi when Bluetooth devices (phones) are connected. In such case the WiFi transfer rate drops to almost 0. Disconnecting Bluetooth helps.
Also there is a know problem called "bluetooth echo" which appears on most MTCD units during bluetooth phone calls. There is a fix available here (again, requires root). For me this is not so important as I don't use Bluetooth calling in my car regularly.
Some devices seem to have a really bad integrated microphone. Attaching an external mic usually helps. My car has ana amplified microphone built-in which I used. It works pretty well. I am not using the built-in microphone from the head unit therefore.
There seem to be unresolved issues about mounting portable mass storage devices. The re-mount after resume seems to take several minutes. Can't comment on this really as my unit only has the GPS card and I rarely use USB/GPS storage to store some music currently.
I also do have DAB+. It works pretty well. I initially bought my head unit with a DAB+ box like this (black metal box with 8-pin proprietary connector). However this never worked and the DAB+ app did not recognize it. Then I went for a simple Joying USB DAB+ receiver like this. This worked very well. Except my antenna setup with stock amplified FM antenna and splitter did not work very well. My recommendation here: Don't waste your money on splitters and amplifiers, get yourself a decent DAB+ roof antenna, install it and you will be happy. I spent lots of time on this as I didn't want to touch my rooftop antenna. Finally I was bout to trash DAB+ as it was just no fun with the bad reception. Replacing the roof antenna changed this completely. I have mounted the Antennentechnik Bad Blankenburg (ABB) 3785.01 with FM, GPS and DAB+ including 20dB gain on DAB+ band. Since then I have very stable reception and I am happy with DAB+ and never used FM again.
There was another issue with the DAB+ application included with my head unit. Always when it was sent to the background the music playback was stuttering. So the application only works when in foreground. Very annoying. However for this there is a modded/fixed version available here.
Hmm, this looks all very complex and many issues. But I am still happy with it. The Android HU allows me to run my own software or use anything available on the play store or even develop some custom solution myself. Currently I am mainly using it for DAB+ playback as well as offline navigation using "Here WeGo" or online navigation using Google Maps.
I am still hoping for the sources to be released so we could make these units a thousand times more useful - but this might remain a dream.

thanks for the excellent info posted there much appreciated. ill probably wait a few months to see what new unit appear but i guess they will have there annoying little issues too. I mainly want mine for gps nav and music via sd or usb and dab radio. not neading bluetooth but will connect to my phone hotspot for online nav.
thanks for the info mate.

Just within the last month RK3368/PX5 units have appeared with what looks like a slightly updated version of MM (different apps), these are the units in the second link.
The 7.1.1 Marshmallow (lol) units are either Allwinner or Tegra based units but theyre not MTCD/E units.
Oreo is being worked on for MTCD/E RK3368/PX5 untis, but its not out yet.

I think the 8 core Android 7.1 units are Allwinner T8. They've been popping up in China the last few weeks

So what does this all mean with the allwinner t8 good or not . I'm lost lol.

This tablet uses the same chip. I'd wait for review on a head unit since software has a lot to say on performance also, but it looks a lot faster than the old ones

It means that they have Allwinner processors.
It also means that theyre not MTCD/E units, so youre in the wrong forum for advice about them.

Like most sellers, Pumpkin have very little idea of what theyre actually selling, theyve just told you the number of cores and the ARM version of the cpu, not the manufacturer.

Eonon GA2168 T8 already rooted
Got my octacore T8 32/2 with nougat 7.1.2 , love it, was no need to root as it already was .
It takes everything i throw at it, all other head units i owned i had to root and su but Igo and all my other apps who normaly need rooting just fired up
when checking with root checker it says rooted
Tried to post screenshots from CPU-Z here but to much work

Eonon are sellers only, there are no "Eonon" units, they sell units from a several different manufacturers, the MCU will tell you who makes your unit.
And youre in the wrong forum - this forum is for MTCD and MTCE units, there are no T8 MTCD/E units, try the Android Headunits General forum.

Ok i now that Eonon is not a "factory" the model is a eonon GA2168 made for eonon with Eonon seal and labels on. can not find simular models from any of the other sellers,only at eonon website..
sorry did not know this was wrong thread as it started out with octacore and a lot of T8 posts.
Thanks for advice to the right forum.

You use the MCU to identify your unit, using that and going through all the threads in the Android Headunits general forum should help you identify your unit.

They are always almost identical. Differences are just the MCU-Version (which is not a important difference) and the Software-Layout.
I have the same Xtrons Unit you postet, but for E46, but there pretty the same thing except for the hardwarebuttons.
I love it, works perfect.
But there is already newer one with Android 8 out.

I heard that on new devices with android 8 often happens cpu-throttling, but I am sure that this will be fixed in the future with some MCU-Updates.

I did see that on the cpu throttling. I also seem to recall reading issues with USB (likely related to the throttling?)...this is a nonstarter for me at the moment given I am hoping to use a resler interface to maintain dsp sound...the resler is naturally usb based

That's just my luck, there was no Android 8 version even listed on the website before I bought :laugh:
I'm still happy with it, everything seems to work as it should, instant start on ignition on, would there be any benefit having Android 8?
