I can't say that the brightness is weak, everything is visible even under direct sunlight. Sunglasses are also clearly visible, but I have special glasses for drivers. I was thinking of sticking the film, but after removing the native one, I saw that the screen was clearly visible and decided not to glue it. But for some reason it seems to me that the screen has become dimmer, because before it was too bright by 100% and I reduced it. Perhaps this is really the firmware, since the screen blinks brighter at times, or maybe it seemed that way to me) But for sure, without a native film, the screen is clearer and looks more solid) In my parking lot, people even look into the car))

For the sake of interest, I'll roll back the firmware, take a picture and take a picture after with a new one!)
[Android Head-Units] MauriBixio:
Well..make the photos...in my case,the display is really LITTLE bright,at 100& during the day it's hard to see what's underneath!

Maybe the display change depending on the vendor\supply... I'm really NOT satisfied with the brightness of this S8 HU... it's useless to have HU that you can't see.

My previous HU by Erisin had a top display, really bright in all conditions, this one by Hizpo was absolutely bad as backlighting.

But... by "film" do you mean to talk about the protective one when the new HU arrives (which is just a thin sheet of plastic) or have you ALSO removed the one above the display glass, which also serves (in theory) as "anti -grease" of the fingers and "fake" anti-glare?

So they are two different things...

If you have removed the one in contact with the display glass, it is certainly brighter since the backlight does not encounter "obstacles" from the film, but after that you will have "greasy" fingerprints on the display glass with the touch of your fingers, and more ...

edit:

Probably these Sx HU have films on the glass of the display like these, but in plastic and not in glass like the link.

https://it.aliexpress.com/item/1005004896153624.html?spm=a2g0o.cart.0.0.171218fcT7YlBm&mp=1&gatewayAdapt=glo2ita

However, even these in glass are not real anti-glare (indeed fake) and certainly stop the brightness of the backlighting of the display, like the default ones.

However, it would be interesting to try to eliminate aol oem film and use these from the link instead... it's cheap, so it's not a problem (probably if I don't solve it, I'll do this test too!).
[Android Head-Units] MauriBixio:
I went now to check in my S8 HU by Hizpo:

the oem film over the display is tempered glass and not a plastic film (seems thick a couple of mm..) i think it's exactly like the one sold in the link above.

Therefore:

who says they have a good backlight, what oem film does the display have,

Tempered glass or plastic?

Maybe that makes the difference between having a good brightness and a bad one...please let me know here.
[Android Head-Units] Aaantonn:
I had an ordinary film, very unpleasant to the touch and unevenly glued, it looked like a protective one for use. But without a film it is a hundred times better, the screen is very easily wiped with microfiber, of course there are prints, but this is not a problem, no more than on a phone, you can wipe it every couple of days. It is unlikely that my fingers will scratch the glass. I removed the film, because on the original screens, for example, Mercedes, there is no film and it looks beautiful.

Here is a video on the old firmware, with film, on a non-sunny day. Brightness at 60%
[Android Head-Units] crv13:
Thx a lot ,i downgraded FW to 0508 and it seems to work fine, at least no more problem with disappearing sound.
[Android Head-Units] castle_rock:
Hi everyone.

I have the S4 version of this unit installed on my car for the last month.

Despite some minor issues, everything has been working fine until now. This week I noticed that wired Android auto was not working, I open ZLINK and nothing happens. But it's a bit strange because when I connect the phone to both USBs, it only charges, no data is transferred to the head unit. Ossuret (the vendor) told me to try with a different cable and phone but the result was the same.

Do you guys have any idea of what the problem could be? I have to say that wireless Android auto never worked, but this was not a problem for me because the wired connection was working fine.

Thanks in advance.
[Android Head-Units] MauriBixio:
So you have my exact same situation as a "film", i.e. you removed the protective one during shipping (simple plastic film) and left everything as default afterwards (you therefore have the same tempered glass film like me), sure.

But... your situation in terms of brightness is VERY sharp, perfect, while with my HU at 100% setting it is at least 5 times LESS than your video, with direct sun, during the day!

Your HU bought from Hizpo?

S8 model?

Maybe my HU has native backlight problems if I compare with your video...

Next days I'll make a video, then if you confirm that you bought from Hizpo, I'll send them mine and your video (if I can make...) so I can complain about my low backlight problem.

Anyone else who owns S8 by Hizpo have low backlight issues in daytime?
[Android Head-Units] Aaantonn:
Who can say what sets up this menu? These settings do nothing at all.
[Android Head-Units] itiswitis:
I believe the screen protector on my unit is plastic. I noticed a few scratches on the screen after I tried to wipe away some dust.
[Android Head-Units] Aaantonn:
I bought from this seller. S8

But I am 100% sure that the screen after the update is not as bright as before. I also noticed a problem with a longer inclusion. Maybe someone knows how to make it so that the radio does not start again when turned on? One of these days I will check and if so, I will write to the seller with a request to review the firmware.

https://pl.aliexpress.com/item/1005005096277274.html?spm=a2g0o.order_list.order_list_main.59.7c6f1c24M9KVXx&gatewayAdapt=glo2pol
[Android Head-Units] MauriBixio:
For me these settings do almost nothing...
[Android Head-Units] MauriBixio:
It seems strange that the backlight could be managed by the firmware, although not unlikely.

With firmware could (but maybe more likely MCU file) fix a certain display refresh rate, or PWM (power led backlight) to a predefined duty-cycle...this could then determine backlight brightness + or - bright. Presumably there should be, if it is like this, a simple menu in which to change these parameters, but nobody knows about it (at least I have never read this).

But we have NO news of all this, only vague hypotheses possible...

In any case, the brightness of my HU is so low that during the day it is practically invisible now (latest firmware and MCU QF1 of June), but it was also identical with the previous firmware...even if with stock firmware and MCU when I had arrived HU actually seemed much brighter to me, ama sure not quanot it should be a car radio!

Hizpo, Ossuret... I think nothing changes, they are sellers, not producers of the HU.
[Android Head-Units] MauriBixio:
Does anyone have this old MCU file available for download?

It was in my S8 HU when it arrived 7 months ago...wanted to try downgrade from current 0207 MCU to this one, to see if it fixes my display low brightness issue.

MCU: QF01.V01.71.20230103.002121
[Android Head-Units] Aaantonn:
Try this 02/07/2023

But it is unlikely that it will help if you put an earlier MCU than this, it is very raw and not everything works as it should on it.

MCU - Google Drive

drive.google.com
[Android Head-Units] Aaantonn:
After I installed the MCU on which everything worked, I no longer change it, only the firmware, since this does not affect anything, only the work of the iron.
[Android Head-Units] MauriBixio:
Thanks, but I already have this mcu 02/07/2023, currently I have everything updated, including June firmware.
[Android Head-Units] MauriBixio:
Right to do so...trying to downgrade MCU old was just a temporary idea...but I agree that it probably doesn't help due to display brightness problem.
[Android Head-Units] zerebede:
There`s your file on Firmware thread. Peace :coffee:
[Android Head-Units] Aaantonn:
How to make the radio every time you turn it on does not reboot? Previously, this blah is rare, but now almost after every shutdown, more than 5 minutes.
[Android Head-Units] MauriBixio:
On cold boot the HU should open the last media that was on before turning it off.

I almost always use the audio player with mp3, and every time I start that one turns on.
[Android Head-Units] Aaantonn:
I have an android download turned on almost every time and I can’t find how to turn it off. Once here in the branches they wrote on this topic, but now it’s not really possible to find this topic.
[Android Head-Units] mk148a:
Hello,

I have qf03 much version do you have any idea about that mcu?
[Android Head-Units] MauriBixio:
Android download what?

Update apps automatically from play store?

Please explain what this "android download turned on" refers to...
[Android Head-Units] Aaantonn:
I don’t know what it’s called correctly, when you turn off the radio for more than 5 minutes, when you turn on the radio, the android starts again, first the splash screen, then the launch, then the home screen. And on the old firmware, no matter how much the radio was turned off, the last open application or the desktop immediately turned on immediately. And before turning on, another 5 seconds of a black screen, before this was not the case.
[Android Head-Units] KLJ617:
Good morning, does anyone know how to play phone Bluetooth in this version? There used to be an icon for it in the Bluetooth app, but it's gone now.
[Android Head-Units] MauriBixio:
This happens to me (cold boot of the HU):

- as soon as I turn on the car, the fixed logo starts (my custom logo)

- then animated android logo

- then load screen of the audio player (last thing I used before turning off the HU).

Note: DO NOT go through the theme's home page in this circumstance.
[Android Head-Units] Aaantonn:
On the previous firmware, at least a night should have passed, so that there would be a cold boot of the GU, and the first two stages were skipped, now constantly. Somehow they wrote in the thread how to fix it, but there were no problems and I did not pay attention.
[Android Head-Units] MauriBixio:
There are surely settings either in "geneal setting" or "fatory-888" (now I don't remember exactly where) to choose the timing for sleep after shutdown, check, after this period, the HU shuts down completely and the new boot will be cold, from scratch.

But someone wrote that this doesn't always work correctly...but I don't remember where to find the fix you're asking for.

With a HOT boot however the HU starts instantly, and starts from where it was previously.
[Android Head-Units] lucky_lucyan:
and I can see very badly in the sunlight, tell me what you solved, what software you have now?
[Android Head-Units] johnnybeacon:
you can disable the robot and keep toppal, its in the settings menu to disable the robot.
[Android Head-Units] castle_rock:
Anyone with the same problem?
[Android Head-Units] MauriBixio:
I haven't solved it (and I don't think retrofit MCU old will solve, but I haven't tried...), and I also think it's impossible to solve, because depends on the backlighting (hardware) of the display which is poorly performing.

Maybe the displays by HU Hizpo are less bright than those from other sellers?

Just a guess, no real evidence.

Is your HU by Hizpo or....?

My firmware and mcu are the latest available, for QF01.
[Android Head-Units] lucky_lucyan:
Hu is Hizpo.

MCU you have the new version, there are some improvements compared to the old one?

can you give me the new version if it is better than the old one

I talked to them and they gave these values:

VCOM 171

AVDD PWM 121

it looks much better
[Android Head-Units] Aaantonn:
I asked a page back what those settings were. They do not work at all and absolutely do not give any changes. How did you get any better? What is your firmware version?

And there are three pages to set up, what did you do on the first one?

How can you have a lot of things if people here also answer that these settings are not working. They worked on the first firmware versions.
[Android Head-Units] KLJ617:
Thanks, but I'm still not sure how to get the phone audio to play. It's been cold booted.
[Android Head-Units] Fugojbc:
Thanks everyone for the replies...

I couldn't pair the OBD via BT even though I followed the instructions, it doesn't matter, I used an OBD adapter with a USB cable. But now the message "TMPS is not working" appears again, is there a way to deactivate the TMPS application? I couldn't find anything in its settings.

Another question, my phone is connected, contact sharing is enabled, the phone book is downloaded to the radio, but when someone calls me, the display only shows the number even though the caller is in the list, can this be solved somehow? Thank you
[Android Head-Units] MauriBixio:
Well, my firmware QF0120230615, mcu QF01230207 (there is no mcu newer than this, same thing for firmware).

Download here: https://autofather.com/s_sjjc

Later I try to set the values as you write, then I'll let you know if things improve, thanks. ;)
[Android Head-Units] MauriBixio:
"TMPS is not working" ...

I have this too, it's a bug in the latest firmware.

If any device is connected to the USB socket, the stock "TPMS" app tries to connect to it, and failing to communicate, a popup message appears.

It happens every time start the HU, right?

The fix (I think) would be to uninstall the stock TPMS app,but it doesn't normally allow to do this.

You would probably be able to uninstall using ADB commands.
[Android Head-Units] Fugojbc:
Yes, every time the HU is turned on, a message appears. Torque also did it, or rather it asked if it could use the OBD adapter, here it was enough to change the OBD adapter back to BT in the Torque settings and it's quiet (I don't use Torque) I use Forscan lite as an OBD application and it also asks every time I start HU if the adapter can to use, the DVR camera that is connected to the second USB is also asking the same thing. What about the phone book?
[Android Head-Units] Aaantonn:
Replace with the latest firmware 2023,06,14 and it will show who is calling. On earlier versions, it does not show who is calling.
[Android Head-Units] Fugojbc:
Can I ask for a link where I can download the firmware? I suppose I'll put it on Flash disc and then run the upgrade. I guess I'll have to reset the HU right? Thx.

Car information system-S Series Upgrade tutorial
[Android Head-Units] MauriBixio:
Tried, nothing happens (as I already saw some time ago, trying to change these parameters...)
[Android Head-Units] MauriBixio:
This is "TPMS" stock app.

If someone manages to make changes to NOT show the "TMPS not working" popup... as written a few posts above.

Or find how to uninstall this with "Not ADB" methods...
[Android Head-Units] tlf55:
Nothing change for me too.. These settings arent working .. Any value change nothing
[Android Head-Units] lucky_lucyan:
with this software received from them, the brightness is better,sorry for the delay but I'm on vacation.this software is special for HUs that have low brightness.
[Android Head-Units] MauriBixio:
What software are you talking about?

Firmware version???

MCU version????

Firmware and MCU are not created by Hizpo...but instead they are the ones we are discussing here in the thread.
[Android Head-Units] lucky_lucyan:
...

I uploaded the software but I see that it is not posted, I will try again,they say that they have had complaints before and they made this software
[Android Head-Units] MauriBixio:
Ok...when you can upload it.

But I don't understand what software you're talking about.

These HU have Firmware and MCU at the software level, the rest are apps, integrated in the firmware, so, what are you talking about... please explain better.

I see you have a civic, do you also have empty Icons on the dash? Which HU do you have?
[Android Head-Units] lucky_lucyan:
I have s8, what do you mean by empty icons?
[Android Head-Units] lucky_lucyan:
I don't have it, it's exactly as it was before, you have a sedan or a 1.0l engine, I have a red dashboard
[Android Head-Units] lucky_lucyan:
you can customize empty icons with honda hack
[Android Head-Units] AlienTekOriginal:
Honda hack? are you using honda hack on a Hizpo?
[Android Head-Units] lucky_lucyan:
honda hack I had on the old HU, I didn't try it on the hizpo
[Android Head-Units] MauriBixio:
This 0328 firmware is FAMOUS for having so many bugs...we talked about it extensively many posts back!

I also used it a while ago...the brightness was as bad as now.

Advice: uninstall this firmware immediately and use the latest of June (everyone who had 0328 did).

If I remember correctly, it doesn't even have theme day and night support and stuff... just lots of bugs.
[Android Head-Units] MauriBixio:
Want to know one of Hizpo's various USELESS tips about low brightness, and how to fix it? (so you laugh a little too as I did)?

"Hello friend, here is the solution.

Solution: Pull down the menu to adjust the brightness or refresh the latest software".

RIDICULOUS tech stuff!
[Android Head-Units] hojnikb:
Just FYI; i was able to fix the unit. It was the stupidest issue you can imagine. Somehow the ribbon cable connecting the front buttons microphone and leds has failed and somehow caused a short. I've replaced it with a new one, cleaned up the connectors and started working just fine.
[Android Head-Units] hojnikb:
If you still have issues; might be worthwhile to check the ribbon cable and connectors. Look at my post above; i had the exact same issue; but mine even refused to boot.
[Android Head-Units] lucky_lucyan:
honestly they are pathetic

I don't even know how many softwares and codes I put until it works well and I have this HU acceptable in terms of brightness

I don't even know what software I have now, I only know that I entered the factory settings, I entered the code 8888, I set those values to those VCOM and AWDD PWM values, I exited and rebooted.

Don't think that it looks great, it just looks a little better, I think it's a problem with the display, they are weaker.
[Android Head-Units] furby2007:
Thank you for your reply. I've sorted it out in the meantime, with the help of Hizpo. They suggested me to access Factory, 8888, Ok. Point 3 Panel key study. I assigned the commands with the appropriate buttons.

Hello,

to which connector on radio should I plug the blue phantom power cable in the antenna (skoda/vw) . Thanks
[Android Head-Units] marioti:
Main plug, G8 pin

Which 2xfakra adapter do you have? This one in your pic is totally rubbish

And you need 2x fakra in one plug, not 2x separate fakra plugs
[Android Head-Units] ghost_kato:
I have this one
[Android Head-Units] Sorrenn:
Hello everyone,

I admit I haven't read all the 16x page comments, but I'm already glad to have found a topic that talks about the problems with these car radios...

so I don't know if anyone has already encountered my problem, which is rather crazy to tell the truth, recently, my "tablet" was literally making actions in autonomy, visible to the eye of course that the touch seems to be solicited by a ghost ... very annoying, because the sound increased alone and it left the carletter alone too, in short, super annoying ...

I decided to do a "factory reset" first, which didn't totally solve the problem, but I'm going to tackle updating the system + MCU in the hope that it will solve the problem...

in any case, if you've already seen/experienced this, don't hesitate to tell me the tips please!

Model : S8 - Android12 Fake? - DSP 31207 + TDA7708 - 6/128GB

Thanks a lot,
[Android Head-Units] marioti:
So plug is ok, but adapter itself not so. But if you have it, worth to try

It is a just a simple and single layout contain only two resistors and two capacitors, witout any choke elemet. look at the first pic, it should look like this. And it is not amplifier but separator (they call it in my country), it give 12+ to the active antennas (by fakra plugs), and separate this voltage against return to device by DIN plug

Compare first photo, to the simple tube adapter (next two photos)
[Android Head-Units] marioti:
I don't remember this kind of issue here.

For me it's a damaged ribbon connecting tape (short circuit) between touchscreen and the mainboard.

This ribbon is very close to the back side PCB where CPU is. CPU become hot often (if you don't modify a cooling). When I modify a cpu cooling i add there a capton tape do prevent
[Android Head-Units] Sorrenn:
Thanks for your feedback Marioti, so I take it that I potentially have to dismantle everything for what this... she's just a few months old, if she's already had a hot spell it's really bad luck I guess... I'll see what I can do in that case.
[Android Head-Units] mk148a:
Guys how to connect fastboot on that device? Via USB? How?

I am get the fast boot from adb shell but I cant connect that device
[Android Head-Units] MauriBixio:
You should have a BLUE wire (remote AMP) which supplies +12v DC when the HU is on.

Connector B | B1: AMP_POW (M+)

Check with multimeter B1(+) with B12 (GND) if a voltage of 12v DC comes out there.

If so, connect the blue wire of the phantom antenna and that.
[Android Head-Units] mk148a:
I am find some things like that https://android.gadgethacks.com/how...mands-from-one-android-phone-another-0384181/
[Android Head-Units] MauriBixio:
I confirm.

What the Chinese sell as an "antenna amplifier" it is actually just an oem adapter antenna power supply splitter, a few passive components inside, simple circuit (with blue wire for power).

Example, with Diversity antenna by BMW this should NOT be used as the HU already supplies the Diversity antenna oem, with VW group cars it seems to me it is necessary instead, Audi too... but I don't have these cars \ brand so I'm not sure.
[Android Head-Units] marioti:
in mobile phones, ghosting mean the touch screen have some damages. it could be damage in producing process, but appear later (like bad soldering or just damaged ribbon tape) in 90% of cases it is unrepairable, and the touch screen have to be change. In your case, i advice to write to the seller, show him a video with an issue, and imo, he ship to you a new screen or whole unit.
[Android Head-Units] lucky_lucyan:
I did a total reset and my side buttons no longer work, the rear camera can be seen in several images and the radio still works like this only when I'm standing still, when I'm on the road it doesn't work
