i found this https://xdaforums.com/galaxy-s6/development/research-memory-management-dha-t3132060 and i'll give it a try changing the build.prop manually.

The magisk module i said earlier was not giving anything, and the build.prop was not even getting changed, so i doubt it was making any diference
[Moto Z Play Questions & Answers] emrepl:
ok thank you..i hope it works.I would appreciate if you inform me :good:
[Moto Z Play Questions & Answers] JonasVFC:
For the first few hours, nothing changed. I'll go back to stock I think
[Moto Z Play Questions & Answers] emrepl:
ro.sys.fw.use_trim_settings=true

can you try to change this code as "false" on the stock build.prop?i am very interesting about why this code is enabled from lenovo.

i think this code is clearing cache when ram usage hit over 2 gb...
[Moto Z Play Questions & Answers] JonasVFC:
it seems better until you lock the screen. after that almost everything reloads.
[Moto Z Play Questions & Answers] emrepl:
the last thing on my mind to try "false" this:

ro.sys.fw.bservice_enable=true

if it works i will unlock and root my phone.
[Moto Z Play Questions & Answers] emrepl:
i found this may help

that phone has 6gb ram, limit=60 is looks like so high for z play.

you can try 30 or over.

seems like there is no solution with build.prop.

did you tryed L Speed app with root access?
[HTC U11  Questions & Answers] sortoh85:
With all this root detecting system, and the upgrades of Android... Is it a plus to root any more?

I am debating that now, only thing I used it for anymore is to truly enable dark mode on my HTC U11 running rr 7 (Android pie)
[HTC U11  Questions & Answers] Tarima:
That really depends on what you want to do with root. I personally think it's worth it, but others have stopped doing it.
[FYT Android Head Units] realzoulou:
I just found new kind of devices on Joyings website and did not yet find any posts about it.

The Android 8.1 based devices are again Intel based, no Rockchip PX5 anymore.

CPU: Intel Airmont eight-core 1.8GHz SC9853i

RAM: LPDDR4 4GB

Flash: Samsung 32GB

Several display sizes are available, all still with the known 1024x600 resolution.

The CPU is an outcome of a cooperation by Intel and Speadtrum (see https://www.anandtech.com/show/12592/intels-last-atom-in-smartphones-a-2018-benchmark),

and another Atom 64-bit architecture spinoff (see https://en.wikichip.org/wiki/intel/microarchitectures/airmont).

The GPU is a dual core Arm Mali-T820 GPU.

Anyone that had a chance to get hands on such a device and could make a comparision to the current PX5 based devices?

Thats very promising. Anybody know if Android Auto would work for phones running pie? So sad i can't get that workon my old intel sofia.
[FYT Android Head Units] deedeebulldog:
No Android Auto does not work. At least the way its supposed to. You can install it on the unit if you have WiFi tether, but that defeats the point. Also the EasyConnected app will not work. Joying said that they were working on getting Android Auto working, so maybe in the next update.

My wife has a PX5 and I had the SoFIA model. This one is much faster. It still has problems like the WiFi randomly disconnecting and reconnecting. Only 1 SD card slot and it has randomly disconnected at times as well.
[FYT Android Head Units] millab:
Have you tried Headunit Reloaded? It's an Android Auto emulator for headunits
[FYT Android Head Units] deedeebulldog:

Joying have their own app to work with android auto and apple play, it is called ZLINK, it works with 8.1, but I am not sure about pie, since not many phone are running pie.

Hello

strange, i cannot install PowerAmp v3 (only v2 is available). I cannot understant, v3 is working with Android 8.1, so the CPU is not supported?
[FYT Android Head Units] Russell_S:
I was faced with this issue as well. The play store would only show Poweramp v2 so I searched the Poweramp forums and it turns out that Intel (x86) hardware is only supported by v2 and support was dropped in v3 and would only support ARM hardware.

However, I posted a question on the forum which you can see here: https://forum.powerampapp.com/topic/16541-intel-based-car-head-unit/ and as you can see I have got it working although I'm still not sure why.

In summary, just uninstall v2, download the v3 apk from here https://powerampapp.com/download-poweramp/ and install it and it should run fine. Then just install the unlocker from the play store as normal (assuming you have the paid version) and it works fine. I'm now running Poweramp v3 on my Intel based Joying unit with no issues whatsoever. Just remember to turn off auto update for Poweramp in the play store otherwise I think it will 'upgrade' it to v2 again.

As I said though, I really don't know how it's working as others have said that they cannot get it to run at all on other Intel based hardware.

Hope this works for you.
[FYT Android Head Units] fabien_m2002:
Hello

thanks it works :)

I have another question with Poweramp, i set volume to 100% and it reduces automatically to 87%! Strange because i disable limiter.

Any idea?

Thanks again
[FYT Android Head Units] Russell_S:
I'm glad it's working.

I'm afraid I have no idea regarding the volume issue. It's not something I've noticed but I may just be anaware of it. Where are you trying to set the volume, on the main unit volume buttons or somewhere in Poweramp itself.
[FYT Android Head Units] fabien_m2002:
In poweramp, in the tone settings (the knob volume) when music is playing
[FYT Android Head Units] Russell_S:
I've not touched those settings in Poweramp, I just use the main unit volume & equaliser. I'll have a look later today and report back.
[FYT Android Head Units] fabien_m2002:
Thanks! I notice another issue: my steering wheel command don't work anymore (next/previous track).
[FYT Android Head Units] surfer63:
A good question would also be: "Do you think only active cooling would be enough?".

I have a PX5 (so not a 9853i) where users do passive cooling, active cooling and the combination of a heatsink and fan. And I don't think that it makes much difference whether you are talking about a Sofia 3GR, Rockchip PX5 or Intel Airmont sp9853i.

My PX5 has a DVD-player and therefore only room for either a heatsink or a fan. I have chosen for the fan, and it is enough AND I leave the lid off (bottom to top: motherboard, fan connected to the case not the motherboard, DVD-player, no lid)

Why?

With a heat sink in a confined, closed space you will always get "saturation" sooner or later. Even the biggest heatsink cannot release heat to "still" air with the same temperature.

Wit a fan you always keep the air moving and you can refresh it (no glued heatsink, no issues with warranty; fan connected to the casing: no issues with warranty).

And: Leave the lid off. Nothing can fall into your unit inside the dash and you don't have to be afraid for dust or these kind of things.
[FYT Android Head Units] merdok:
Thanks that is a good perspective. I guess I had hoped that had similar thermal throttling of ~2015 era android phones where didnt require active cooling.

I put medium / large (aluminum) heat sink and exhaust fan out the top on my sofia and worked great. I guess I will do the the same here. It arrives tomorrow :)
[FYT Android Head Units] merdok:

How does the reverse camera work? Do I need anything else other than a live RCA video feed in to the camera in socket?
[FYT Android Head Units] merdok:
I still need to wire a reverse cam I have had sitting around. I believe you pull power from reverse lights to switch it on and off.
[FYT Android Head Units] twokidsandaphone:

Wrong.

I've done that - camera is powered up and works as an aux input.
[FYT Android Head Units] blinger:
I have a similar problem with receiving Bluetooth calls. Sometimes when I answer a call, the person can hear me for the 1-2 seconds and then they can't hear me. But I can still hear them.

Did you find a fix?
[FYT Android Head Units] surfer63:
No, it is not. It is on the PX5 as well. Somewhere in one of the long PX5 threads it is explained by one of the hardware guru's (@looxonline ??), but I can't find it back.

It has something to do with accessing the unit/cpu/mcu or so via some serial method (afaik), but don't shoot me if I'm wrong.

Anyway, as end user you can't do anything with it.

Thanks. Because you seem to know the board, you know what the 5 pin is along front left of board is? Probed it and didn't appear to be usb based one pin out of other two 5pin port used.

I was kind of hoping that it was not usb with 5v after buying a 12v fan lol

[FYT Android Head Units] pajo985:
How?

Have you done some modding, or?
[FYT Android Head Units] bommelkopp:
No

No. Connected, searching BT devices, done
[FYT Android Head Units] surfer63:
It has nothing to do with brand of OBD dongle, but with the internal name of the OBD dongle and its pincode.

Only OBD dongles whos internal BT name start with OBD can be paired.

And you need to note down the pincode of your BT dongle. If it is different from the default pin code of your device, you have to first forget your phone, then give your Joying the pincode of therOBD dongle and pair it, then pair your phone again.

So if you scan for BT devices and your dongles name does not start with OBD, you can completely forget it.

Following this, I used a real OBDLink LX for years on my MTCD device. Connectivity was not reliable.

[FYT Android Head Units] 4eyeMonster:
Does anyone know of a tool I can use in order to change which apps a certain button on my steering wheel activates?

For example, my "source" button shuffles through the different default apps on my Joying 8.8-inch. Once goes to radio, hit it again and it goes to the built-in music player, hit it again and it goes to the default navigation app, but there's no way to select other apps or take the built-in ones out of rotation.

Ideally I'd like to be able to use the "source" button to switch between CarPlay (zlink), my OBD app, and the equalizer.

Is there a decent way to customize this? I've got the HQS01N4G for what it's worth.
[FYT Android Head Units] surfer63:
This is partly possible using my FytHWOneKey app.

The source button is an "intelligent" button. It checks for hardware and connected devices. If you have a DVD player and a DVD app, the DVD app will also be added to the Source button. If you have a phone connected to the bluetooth button, it will add that to the source as well.

The BT options do not really work, but the radio, mediaplayer, DVD (if available) and a few other options can be remapped.
[FYT Android Head Units] jburner:
Newb here, and joying not much help... Anyone know why my Tuner wouldn't work after flashing update to my Joying radio (JY-TQ187N4GN). The Radio (Tuner) app starts up, but no sound, no scrolling works to find stations, no AM at all, settings only has FM sensitivity and manual. No RDS, or AM shows up. All of this worked prior to update. (I never should have done an update!)

Everything else works fine. I've tried factory resetting and re-flashing and still the same thing. Any ideas to fix this? Thank you.

I want to sell my 10.1" Joying SC9853i . How do I wipe all the data on it?

I installed the latest April 2020 firmware and that reset all the settings, but pics & apps were still there.

Then, I tried all three options in the resettings menu. Again, it resets settings, but all pics & apps are still there.

The "Erase all data" option *says* it's going to wipe my apps & pics, but it doesn't.

EDIT:

I figured it out.

I added a new text file to the root of the firmware update USB stick with these three commands.

I did that per suggestions on the modding thread. And it worked great. No more 3rd party apps and all my pics & things on the SD card are wiped.

Hi Guys,

I own one of these babies since 2019, updated it with 2020.4.7 patched, installed FCC Launcher and using literally only one App since then (Calimoto, a Navigation App) as this is just in a fun car which is used very very rarely...

Last weekend I wanted to use Maps but it a) didnt talk to me and b) crashed continously after ~30minutes.

I do remember there was something about Maps not working properly, but I dont remember what it was exactly or there was no fix these days....

Believe I rooted it to install MacroDroid to kill the Radio App and have more control with FCC.

Is there something I could do to fix that Maps issue?

Cheers
[FYT Android Head Units] surfer63:
Unroot it. The rooting kills the TTS which Maps uses.
[FYT Android Head Units] cottec:
Argh, wasn't there a way to hide it from Google?
[FYT Android Head Units] surfer63:
No, "normal" apps can be excluded by Magisck.

But Google does different things and can't be "tricked" into thinking that the unit is not rooted.
[FYT Android Head Units] cottec:
Hm is there any different TTS available? What a shame Joying stops support after literally 2 updates...
[FYT Android Head Units] surfer63:
It is not the TTS.

It is Google via GMaps not accepting a rooted unit. Another TTs won't help, I think, but you might try.

And there are others (in the margins of Google TTS). Look in the play store.
[FYT Android Head Units] cottec:
Hm okay, might go back then... is there any draw backs for FCC or so?
