[Android Head-Units] VRUIZGAR:
Hola buen día, tengo el siguiente problema, la pantalla de mi radio dejó de dar imagen, al parecer es la retroiluminación la que no funciona, el proveedor me dijo que midiera voltaje en algunos terminales de la placa base, y efectivamente no hay voltaje, no se si a alguien más le ha pasado esto y si es así como lo solucioné, muchas gracias.

Hello, good day, I have the following problem, the screen of my radio stopped giving an image, apparently it is the backlight that does not work, the supplier told me to measure voltage on some terminals on the motherboard, and indeed there is no voltage, I don't know if this has happened to anyone else and if so, how did I solve it, thank you very much.
[Android Head-Units] PrinceLc:
It's a common problem the SIM card and 4G antenna is the problem, solution is to take away the SIM and maybe a new Flat display cable
[Android Head-Units] VRUIZGAR:
If in fact I no longer had the SIM card in, it seems that it does not send voltage to the backlight supply, not if it is linked. I will try to get a new screen cable
[Android Head-Units] PrinceLc:
Tomorrow my new cable must arrive I hope so than I will inform If it resolve the issue
[Android Head-Units] VRUIZGAR:
My screen is giving an image, what happens is that the backlight does not work, but if I shine a flashlight on it I can see the image
[Android Head-Units] PrinceLc:
Open the headunit and check the connection of the cable
[Android Head-Units] VRUIZGAR:
Now, what happens is that in the conoctor, it marks me zero volts
[Android Head-Units] PrinceLc:
Zero volts not good hope it's only the cable
[Android Head-Units] MauriBixio:
0 volt = probable problem with the PWM section that powers the display... PCB mainboard hardware problem, if you see an image in the background with the light of a torch in the distance... investigate that.
[Android Head-Units] VRUIZGAR:
thanks

Car information system-Display Screen FAQ
[Android Head-Units] TigTex:
How is the Wifi range of your devices? I'm having issues connecting to a hotspot from my phone running on the car itself (2.4 or 5ghz, no difference). The signal is strong, but if the device is not exactly on top of the unit, internet connection is lost. Looks like firmware issue or lack of Txpower, but I have no other unit to compare it. I can even see my home network, but connecting to it results in no internet (sometimes it adquires an IP, but it dies almost immediately after connecting)

Yes, the crappy blue wires are connected to the correct place. If I remove them, I get no signal at all.

It's a S2 unit with the latest MCU and November FW. The original MCU and firmware also had this issue
[Android Head-Units] Vampire_Dracula:
Thanks.

I installed on on my wife's S8, purchased from Breteuil Factory Store, for a 2011 Toyota RAV4.

All seems to work fine.
[Android Head-Units] chadoe:
If I park in front of my house I can connect to the router on the other side of the house no problem. My S5 has an antenna sticking out of the back though, not just the wires that older versions had.
[Android Head-Units] PrinceLc:
New display cable mounted and now test and hope no black screen with SIM anymore
[Android Head-Units] Vampire_Dracula:
A can see a new option for a 360 camera, in the factory settings.
[Android Head-Units] MauriBixio:
These radio do not have the hardware on board to manage 360 degree cam, so it is useless.
[Android Head-Units] Vampire_Dracula:
Yes, indeed. But it seems to be optional. You have to ask for it during the purchasing process. This is probably the reason for updating the software.

I only updated to get access to dual Bluetooth, since her unit had the August firmware. Going for the most recent firmware made sense to me.
[Android Head-Units] MauriBixio:
I also remember that there is the option to choose the 360 cam hardware before purchasing... but I don't remember anyone here who has done it.

This 360 option seems to me to exist via firmware even in previous versions, it is not new (but I might be remembering wrong).
[Android Head-Units] Vampire_Dracula:
I still have the October 13th firmware on my 2019 Honda CRV. There is no 360 camera option. See below. So it must be new, part of the November firmware.
[Android Head-Units] MauriBixio:
I probably remembered wrong. In any case, it is an option that cannot be used without on-board hardware.

However, it's good that they have implemented it in the firmware, perhaps for future radios/PCBs they will insert the 360 cam hardware as default...
[Android Head-Units] MauriBixio:
"Maybe" this 360 cam hardware is not compatible with our Sx radios...but it would be interesting to find out! ;)

To finish the 360 cam hardware topic, MAYBE this is for MB with UIS-7862 chip on board, like Sx units... but it's just HYPOTHESIS, nothing real.

It does not have a flat cable, but should be soldered directly onto the MB.
[Android Head-Units] Devuser6:
Hello guys. I'm new here and I would like to thank everyone for the valuable advice in this thread. I have a problem because I installed new software from the seller in November, and the navigation on the main screen in the window where the picture of the car shows is not displayed. I changed to October firmware and it didn't change anything. Radio S8 from Hizpo. Anyone know how to fix this?
[Android Head-Units] PrinceLc:
Update black screen fixed by changing the flat display cable yuhu
[Android Head-Units] Clyde72:
I noticed the differences in last numbers for mcu once installed. But keeps me puzzled because 2 times I could update fw & mcu with files shared for S8 (1126 & 1216) succesfully on S4... My last update was with 0104 auto_update for S5 but it seems to have updated only the fw. Still have to try updating mcu with the 0104 mcu file for S5 seperately.

Can be that the first 2 updates were lucky shots...

----------------------------

Just tested the mcu, wouldn't load either, so possible mcu backward compatibility between S5...S8 and S1...S4 was a false assumption/hope of me.

I looked somewhat closer to mcu files shared, though version can not be determined by the file properties there is clearly a difference in file size. 47 kB vs 33 kB. The mcu.bin tested and not loading was 47 kB in size. The bigger mcu files are from S5....S8
[Android Head-Units] CieploZimno:
Yeah, This wire is not connected on my unit too

Yep the fan turn off.

But sometimes, i can hear a noise like "click" every 10 or 15 sec when I take key out, which come from the central console

And when i disconnect the canbox this sound stop...
[Android Head-Units] Clyde72:
I had asked the seller about the sleep issue right after I got the unit installed and tested (my wiring was all ok). Sleep code with delay worked well but later on I bypassed the canbus box completely (annoying reversing process a.o.) and even bypassed the quadlock cf. existing iso kit with FM booster.

Never got any answer for the fan connection question btw be has meanwhile been discussed in the thread...
[Android Head-Units] theAtotheG:
So yesterday I pulled the head unit out and unplugged the external mic and the fan, to see if it would have any impact on the quality of the microphone.

It did. The call quality is much worse, both in CarPlay and the stock dialer, but Siri does seem to hear my commands now.

Other posts have talked about an engineering menu. Has anyone found access to it or hidden Android settings?
[Android Head-Units] nyp42:
Maybe these units have a poor ADC. I wonder if a USB mic might sound better.
[Android Head-Units] Clyde72:
Engeneering menu? Do you mean factory settings?
[Android Head-Units] theAtotheG:
It doesn’t seem to be. Here is another post that talks about it.

It thought you meant posts in this thread here. For our system/platform...
[Android Head-Units] DCB103:
Think he means developer mode where the code is in the first code

114477 - activates developer mode (Than you have to do the usual procedere: touch the build number on the system info screen several times until it says that you are developer now.)
[Android Head-Units] Clyde72:
I think he knows this allready as it is mentioned in the first post and more in this thread. As for hidden android settings - I didn't try - but it is Android 10 so secret codes for Android 10 maybe work by using the dialer.

In general as we do not know how to get into recovery mode yet it's maybe wiser not to thinker with system (wide) settings too much (yet). Just my opinion, I'm not that tech savvy and I like the unit's smooth functionality since I installed it in my car even with its flaws.
[Android Head-Units] DCB103:
exactly, besides small issues (delay of lights in my case and setting the multi display time and date of my car) all works without problems. I always say "dont try to fix it if it is not broken" :-)
[Android Head-Units] Clyde72:
Yup 😉

Looks strange but it works and i can live with it
[Android Head-Units] Clyde72:
There is space enough in the center console for it
[Android Head-Units] lefterisa3:
Its has a full double din...

it can fit even a small pc
[Android Head-Units] Clyde72:
Possible you checked this allready but does the unit still powers on in fact? Ever tried changing the mini fuse? May look like a stupid question but I just thought of it now. Not always the most reliable or accurate fuses in Chinese gear.
[Android Head-Units] Clyde72:
I know, some years back I found 2 Parrot mute boxes 😅 in there and way deep. Must have been left there from old installations
[Android Head-Units] Vėžys:
From stupid questions, sometimes geniuses begin.

Everything is good with a fuse, otherwise it would not show anything
[Android Head-Units] sandub:
after replacing this cable, you no longer have a black image when using 4G sim ?
[Android Head-Units] PrinceLc:
Right today the cable was here and replaced it
[Android Head-Units] PrinceLc:
It's working on November firmware maybe you unchecked erase user data right on upgrade
[Android Head-Units] Astralech:
I have the same problem after updating the software to November, and after rolling back to October, nothing has changed.
[Android Head-Units] Astralech:
These cables were used on the green motherboard versions of the units and there were no black screen issues. Problems started with the new version of the board and cable (probably cheaper).
[Android Head-Units] PrinceLc:
Maybe I don't know my first QF001 device and yes the standard white cable is cheaper than this golden
[Android Head-Units] Barykelo:
Hello. I have this problem with my new S6 and S8. Both of them started showing errors and typos on the touch panel. The text is almost impossible to write. It probably all started after a hard reset (22558800) after a firmware update. I also wrote Hizpo. I did a touch calibration but no luck. Does anyone have experience with this?
[Android Head-Units] Devuser6:
Erase data is checking, but I noticed that not all start screens have this problem. I did a factory reset and now the side buttons don't work and I can't program them at the factory.
[Android Head-Units] JP202:
i have the Hizpo S8 single din 10in. screen that has worked fine all year. About 2 weeks ago the sleep mode stopped working, and today the screen went black. Touchscreen still works, just can't see anything. Is that a backlighting issue, and could it be fixed? Or do I need to replace the whole screen unit.
[Android Head-Units] PrinceLc:
Had this with side button also and I could Programm it in Factory settings

[Android Head-Units] PrinceLc:
And what model do you have ?
[Android Head-Units] Devuser6:
I have S8 model. I uploaded the software that was already installed in it and it worked. I got them from the seller.

Is there any way to force a new update now?
[Android Head-Units] PrinceLc:
In usb put folder QF/Auto/update.zip and restart with usb plugged in normally it detect automatic the update
[Android Head-Units] Devuser6:
Ok, thank You i try this now
[Android Head-Units] PrinceLc:
When not try 4 times to force reboot the unit than it will go in recovery mode but press the rst button when the boot animation will come
[Android Head-Units] Devuser6:
Unfortunately, it didn't help. I made the QF and auto folders and copy the update file in and restarted the radio by disconnecting the power supply, the reset button doesn't change anything either. The logo comes on and that's it.

Hello, I have some doubts, first excuse the English/google... I have this screen that was installed for me, sometimes, when I turn it on, the screen turns black, they already changed it for that problem, the screen, but it is still the same, it rarely does, but if it does, if I click on the restart that the screen carries, it restarts and works well.

Another big question I have because the seller doesn't give you information, what screen do I have? What brand is it? How do I know if there are updates?

Thank you
[Android Head-Units] Maferto:
Creo que solo es un canal de información, no se puede escribir

Hy use it without SIM card or you need to change the PCB Flat Display cable
[Android Head-Units] sandub:
In the Settings-About interface, click the system version number continuously and then take a picture of the screen parameter ID version information
[Android Head-Units] sandub:
based on screen parameter ID version information ,and the seller can send you the cable

[Android Head-Units] Yevhen7788:
The first photo is on version 2.62, but the second is on version 2.68
[Android Head-Units] PrinceLc:
The version of Carplay ? Because ZLink is version 5.4 on the S series of head unit
[Android Head-Units] Yevhen7788:
On 2.62 the version is 5.3, and on 2.68 the version is most likely 5.4

Does anyone know how to change DPI to some apps?

If I change the DPI to the whole system, the launcher and the stock apps don't adapt to the new DPI settings even after a reboot.
[Android Head-Units] PrinceLc:
Did you try it with ADB Shell ? wm density 200 or another value?
[Android Head-Units] ulbx:
This is what I tried. Almost all the apps other than the stock apps were working perfect.

The problem occurred to the stock launcher, menu and the stock apps like radio, music, etc.

Everything is too small, other than the stock apps on the 7inch (1024x600).
[Android Head-Units] PrinceLc:
Yes Like in Mine 1280x720 10.1 Inch but I use Agama launcher and DAB app I have set the density to 190 it's okay
[Android Head-Units] ulbx:
I use radio a lot, so I will have to find another app that work with FM. Other than that, most of the other apps can be replaced with 3rd party ones, I think.
[Android Head-Units] PrinceLc:
Try Navradio+ maybe
[Android Head-Units] MauriBixio:
It would be interesting to also be able to enlarge the size of the fonts for Google, YouTube, Play store, Chrome etc. because even with 9" 1280°720 everything is too small.

You can enlarge the Android system font size by setting it to "large" (with the Android settings) but everything is still too small (my age is advancing and my eyesight is decreasing!)

There are apps to increase the font size, but they don't work completely (at least the ones I've tried) They DO NOT increase the font size for the Android/web apps I indicated above.

Has anyone tried any apps that work?
[Android Head-Units] spamplemousse:
Hi

This device makes me go crazy....

Initially I had black/white screen issues when using 4G, Hizpo support is sending me a new cable to fix that.

In the meantime I was using wifi hotspot, it was more or less working (still a lot of random reboots, or application crash).

But this morning, the device worked for 2 or 3 minutes, then reboot by itself, and is now stucked on the Android boot logo.

I tried to reset it, no change, still stucked on this logo...

Did someone experienced the same issue? How to fix it?
[Android Head-Units] PrinceLc:
Set density to 240 and than go to Android settings there is a 🔍 symbol and search for Display or Screen size or so
[Android Head-Units] PrinceLc:
When the device goes to the boot animation than press 4 times the rst button every time you see the boot animation press the rst 4 times normally it wold go into a half baked recovery and it erases all to factory reset.
[Android Head-Units] spamplemousse:
I already tried to press reset button several times, or long press, but no change... :/
[Android Head-Units] PrinceLc:
I mean when you press then Powerd by Android logo and than the boot animation after a few seconds press and this procedure 4 times
[Android Head-Units] spamplemousse:
Here is what I just tried :

Press 4 times during the "powered by android" logo

Press 4 times during the "android" logo

Press one time during the "powered by android" logo, then doing it again 4 times.

Same thing, but during the "Android"

And also tap the screen several times with 5 fingers.

Still no recovery... :/
[Android Head-Units] PrinceLc:
Hm ok that's odd what about when you put an usb stick with firmware and do the same ?
[Android Head-Units] spamplemousse:
I had a usb stick ready with a firmware (I was waiting for the new screen cable to install it), so I just tried (twice, with the 2 usb ports) : still the same.
[Android Head-Units] refsada:
copy updaze.zip copy to a USB stick (fat32 formatted)

Key cable to the ground

turn on a device

When the Android animation comes, let go of the key cable

The device boots into recovery and leads an update
[Android Head-Units] spamplemousse:
Key cable to the ground? I'd have to re-open everything???

I'm facing this issue from nowhere, until this issue I din't tried to update or whatever, and now a I have to open everything to put a cable of the device to the ground?

Not against you, thanks for the support, but what a ****ty device....
[Android Head-Units] refsada:
If you haven't done, then there is probably a device defective and you have to exchange it.

I know I'm not happy with it either :)
[Android Head-Units] spamplemousse:
And so, as explained on telegram, I can't follow the "ground key cable" procedure.

First because I'm not sure of the cable (there's a "KEY2" cable, no "KEY" one).

And especially because everything is in plastic in my car, there's nowhere to ground.

And yes, I guess I'm facing a defective unit, as I never tried to update it or do anything special with it...
[Android Head-Units] Scale&Hardwarebox:
Has anyone ever tried connecting the Android radio to ambient lighting via Bluetooth? Somehow this doesn't work for me. A few months ago I installed ambient lighting in my vehicle. This is operated with a Bluetooth module. You control the whole thing via your smartphone. For this I use the app magic lantern. This also works great. Now I thought I could also control it via the hizpo radio. However, I am faced with two problems here:

The radio cannot find the Bluetooth adapter; it is not displayed in the list.

Whenever I start the Magic Lantern app it automatically quits after a few seconds. Does anyone have an idea what this could be or could it simply be that you can't control it with this radio due to incompatibilities?
[Android Head-Units] MauriBixio:
But does this method increase the dpi of everything, even non-stock external apps?

I would like to increase only the text of the Android "web" apps, not everything on the device.
[Android Head-Units] PrinceLc:
Everything will be increased
[Android Head-Units] MauriBixio:
In this case I can't use this solution, for some of my apps I can't increase their size/DPi... thanks anyway ;)
