EDIT: XDA didn't like me attaching the photos, just got broken links so I'm sorry that they're embedded like this.

Joying just sent me a review unit of their new 10.1" Android 10 head unit so I figured it should have its own thread. It looks like they're pumping out updated versions of all their previous devices by the day so I imagine they'll have versions of this in all the different screen sizes soon. First impression is good. The interface is appreciably more responsive than the Intel unit I currently have in the car. I'm working on some videos but figured I'd throw some pictures in here. Here is an unboxing and interface tour video: https://youtu.be/h__Zc0fwOtw

The PCB looks is clearly iterative but looks to have some significant redesigns, especially with the power supply which is much larger than on the previous Intel design, through that might be required for extra derived voltages for the new UIS7862 SoC.

The previous Intel PCB used an STM32 MCU in between the main SoC and the bluetooth module which probably contributed to the difficulty interfacing Bluetooth devices that weren't specifically allowed by Joying. The area where this chip was now looks to be filled with power components though the same Bluetooth module is still used. I'm hopeful that this means there's direct communication from the SoC to the BT module, but that'll take more digging to determine. There is also a new general purpose ARM Cortex-M4 MCU added between the SoC carrier board and the DSP chip (GigaDevice GD32F330R8T6). I'm curious if that's taken the place of the old STM32 chip or if it's used for something else. Hopefully I'll be able to determine what it's used for, but I'm not touching anything until I get it installed and reviewed.

The green PCB is the Intel board and the yellowish one is the new Android 10 board. Of note is the fact that the new PCB has Joying's name silk screened onto it where the old Intel one didn't. So, at bare minimum, this board is spun just for Joying, even if the only differences are the silk screen layers.

Any requests for specific details?

I'm just curious about:
- How's the WiFi speed, especially in combination with Bluetooth switched on and your phone linked (was absolutely terrible on the SC9853i's due to combined frequency/bandwidth use)
- Does Google Voice work with phone calls?
- Has CANbus functionality improved? Especially: does it now support 2-way Airconditioning control? (previously it was only possible on Ford AFAIK to also raise/lower temps from the Airco app)
- which launcher do they now use/include (do they include the T'eyes launcher or some look-a-like?)
- And like you already mentioned: what can be connected via Bluetooth? Still only Joying/FYT "allowed" hardware?

I'll work on these today and tomorrow but I can answer the launcher question. Thus far it looks identical to the launcher on my current SC9853i unit with the exception of a slight tweak to the EQ app which adds the ability to set a Q value for each of the fixed frequencies.

So I'm looking at buying one of these new Android 10 Units.....Seems like they have a 7" Version SKU: JY-UQS03N4G with the Dual ARM Cortex0A75 but cant verify its the same hardware.

I currently have the PX5 Android 8 version.

So Im wondering the following:
So hows the sound quality?
The Android Auto/Apple Auto working? I know there were issues with the version I have
How fluid/Quick is the touch screen?
Any negatives you have noticed so far?

I can answer most of the questions in the next day or two when I get it installed in the car, but I'm pretty sure that it is the same hardware. From what I've seen they just slap different screens onto one or two head unit bodies (not sure what else to call it...) and that has the same 2x A75's and 6x A55's but also includes the 4G module that mine doesn't have. Looking at the PCB I really wonder if the radio isn't already there and they just don't populate the antennas and remove the mobile data option from the firmware.

I put together an unboxing, initial impressions and quick interface tour video: https://www.youtube.com/watch?v=h__Zc0fwOtw I'll have an install video coming out soon and a full review. This has been my first experience trying to make videos like this where I actually have to talk :eek: so I'm still trying to figure out how to put them together and how to not stumble through all my words :p

First impressions of this unit are very positive, though I'm expecting to be more critical in the full review once I've had time to test everything out. I laid into them in my review of the Intel unit I bought for a bug that resets all the trip computer units to metric every time it reboots so I was surprised they sent me a review unit :confused:. I'm hoping that bug is fixed, but I highly doubt it. I'm really interested in seeing if they managed to eliminate the slight hiss (EMI) when nothing is playing and it's not muted. The expanded power might help with that, as well as the fact that the SoC carrier board has shrunk and there is more clearance between it and the DAC output traces.

The first bug I ran across is a small one, but it's very difficult to swipe away and close apps in the recent apps screen. Like, you have to grab it at a very specific spot on the icon and drag it all the way to the edge of the screen... That strikes me as a strange one but it's actually somewhat infuriating so I hope it can be fixed.

I believe the CPU on this board is the Unisoc Tiger T618. Its specs most closely match the specs that we already know, except the 2 Arm A75 cores are supposed to be at 2.0GHz stock. The T618 is a 4G chip so the modem would be built in, but disabled via config file. You could solder on the antennas and also solder in a SIM tray and then enable the modem and it should work. I've already learned that the chinese resellers will cripple their devices to sell "features". Teyes is a great example, they will disable certain bluetooth features unless you pay for the more expensive model. I believe the resellers have few versions of boards, mainly ram and storage difference, maybe DSP difference, but that's about it. It is their decision to disable/omit 4G only to sell it in a more expensive model. It is not like regular phone manufacturers that will disable features via efuses or different chips.

Joying/ joyus simply reducing manufacturing costs and maximising margin/profit.

I could be wrong but think these will be mostly a port of previous code, complete with old and new bugs but on "cost effective" hardware.

I'd also assumed the 4G functionality was already included, simply because of the cost required to have multiple different parts. The antennas pads are kindly labeled on the PCB and there's already a header for the SIM tray so no soldering required for that part, assuming the pinouts are the same. I'd be interested in trying it if someone were able to figure out how to edit whatever files are required to enable the functionality in Android, if it's possible. I've even got the SIM tray and antennas from one of my units that I broke so the swap would only take five or ten minutes.

he Bluetooth on the previous version had a separate STM32 MCU in between the main SoC and the Bluetooth board and I'm pretty confident that was acting as a gatekeeper and is what prevented us from easily adding functionality. That chip isn't present on top layer of the new PCB but it could be hiding on the bottom. I'll find out when I pull it all apart (after I get it installed and do the review lest I break something:rolleyes:)

I remember in the sc9853 thread there was mention of a crruptoff file you place while flashing to basically disable the no sim card message if it's missing the sim card. But I'm thinking that configuration information is stored inside the fytdata partition that the resellers pretend doesn't exist.

Love your reviewing everything. I went ahead and ordered my unit since it has to come from China and that will probably take months.

You'll be surprised. Each of the three units I've ordered from them have come in (Minnesota, USA) exactly one week from the date of order, though I imagine that may be a or two more depending on where you live.

Well i ordered from their website and when i checked the US warehouse they didnt have the 7" version. So i dont think ill be that Lucky but one can hope

All mine have come from the Chinese warehouse. Two have come via DHL and one via FedEx. DHL is especially fast. The darn thing will land on the east coast at 4am, then make it to Minneapolis by 10am, and by 11am it's on a truck for delivery. That's been my experience with them every time I've ordered things from China with DHL.

This worked in the previous PX5 Firmwares and early SC9853i firmwares, but it no longer works.
I assume they removed the check for the file.
