I purchased the following Joying JY-UL135N2 5.1' Lollipop. 5.1.1 Lollipop Intel SoFIA 3GR Quad Core; RAM 1GB ROM 16GB [Stock ROM]
So whenever I increase the volume to 20/30 while playing music. It cuts the noise/mutes. I have to press the reset button, after the unit resets, the volume comes back on. It is kind of getting frustrating. Im confused if it has to do with wiring/ or its a software bug. I checked the wiring so quite sure it has nothing to do with wiring. Any help would be much appreciated!
I am running no amp right now, just 4 ohm speakers FYI. T

Just check one speaker at a time and see if it still does it , it could be a speaker problem .
Make sure you disconnect the other speakers to don't do by fader and balance

My speakers are pretty new. The connections seem fine as well. How can speaker cut the sound? curious.

If the power drain (listening very loud) is too big and the unit can't take it I guess this is the outcome... I guess that's why on some units there is a BIG capacitor to help with those power peaks... and in this one is a little one
I am not expert but from what I have read it could be an possible explanation.

Another possible explanation is that the audio amplifier chip has an onboard thermal sensor which is triggering a shutdown of the chip due to temperature. Is there a time component, ie the first audio cutoff takes longer than a subsequent one if you resume playing at the same volume? Or what happens if you just play the front or just the rears?

Dude Thanks!!!!!! It was my Rear left speaker, after I disconnected it , the volume doesn't cut off. So there was a short on that speaker wires. The Joying unit is fine.

Most welcome mate ??
Just as a little side note something to try if you already ain't , hook the speaker cable back up to the head unit and disconnect the speaker if the unit cuts in and out still its the wire if not check the speakers little leads from the connection to spider sometimes they slap against the basket of the speaker causing the short , if so just bend it out the way a little.. ??
Hello, I recently installed the above Android unit into my 2014 Mitsubishi EVO with Rockford system. It came with the can bus decoder MT-SS-03 for 2014 Outlander. I set everything up in the factory settings menu but I'm having a major audio problem that sadly is ruining an otherwise awesome experience.
If I listen to any music at high volume all system audio cuts out completely for 5-10 seconds at a time. I've found this problem is directly related to the volume. The louder it is, the quicker the audio will cut out. I've double and triple checked all wiring and pins, updated to the latest MCU 2.59, Android system (8-3-2017), etc.
I'm out of ideas on what to try next but hoping someone here can shine some light on the situation. Thanks in advance and looking forward to putting an end to this issue!
do you have proper canbus?
Yes I do, according to them. I did get a red one though which was labeled for 2014 Outlander which I understand to be the newer can box for 2014-2015 EVO but the pictures I've seen show a black box and mine was red but labeled as the newer one. I thought the older 2008-2013 units were red. Not sure if that makes a difference or not but I do have sound from all speakers so it works it just cuts out at high volume. However, the amplifier settings on the Android unit do respond a bit strange. The sub slider seems to change all speaker output and not the sub directly and has a pretty minimal effect. The fader seems right at least as far as the channels go.
In the meantime I did contact the seller on Amazon about the issue. They told me the issue is caused by the high power protection of the factory amplifier. To fix the issue they want me to re-install the factory radio, turn the volume sliders down to the "middle part" and then install the Android unit again. This seems a bit strange to me but it could be the factory radio interfaces with the amp in a different way and is able to control the gain of the sub and the Android unit cannot. With the newer Android unit I noticed the max volume is much louder so maybe I'm hitting some sort of over current protection causing the amp to momentarily shut down. Has anyone ever heard of this?
What I'm not sure about is when this procedure would be needed. Is it because I had the amp slider on factory unit is set too high before I removed it or is it because I disconnected the battery and the amp defaults to a higher setting that only the factory unit can adjust? It would be a real shame if every time power is cut from the amp I need to repeat the process. I fear that may be the case because I'm not sure the amp has an internal EPROM or non-volatile memory that's saving the settings and I did in fact disconnect the battery.
Either way I'll be happy to finally get to the bottom of the issue and I'm sure I'll find out whether or not I'll need to swap the radios again. Until then I'll keep the factory unit closeby. Luckily it's very easy to swap out so fingers crossed this fixes the problem. It's going to be a few days till I pull the radio out since I'm also waiting for a replacement USB harness since one of mine is inop due to a damaged wire.
Please let me know if anyone has any input about this. Thanks again.
Ditto - did you try swapping back and lowering the volume, if so, did it resolve the issue?
I have only had mine for 3 days, Dasiata HA2106-S720 with Dasaita CB003 Canbus harness in a 2013 Mitsubishi ASX with Rockford Fosgate. I would agree that the volume seems higher, so there could be some truth in the Sellers theory.
By the way my experience with Subwoofer control also matches yours - adjusting the lowest frequencies on the Graphic Equalizer seems to affect the main speakers more than the subwoofer, and I am not getting the same 'punchy' bass as the OEM Head Unit.

You made also the Car Settings to work well ? Things like keyless operations, windshiel wipers operation, lights time out, auto fold mirror, etc ? Thanks.
Hi there,
Since this is my first post i want to say hello to everyone!
I decided 3 weeks ago to buy an android head unit for my audi a3, since i was bored listening radio or audio cd;s only...
Audi OEM RNS-E navigation was an option but it's too expensive just to have navigation, bt, and mp3 in my car... so i decided to go for an android hu that fits my dash...
I found this Xtrons android HU and bought it....
I was aware about the poor sound quality BUT it's actually VER VERY bad!!! on standard 10 speakers Audi sound system... (i was ready to root the device and use viper4android, or any hardware mod to improve the sound)
BUT I was lucky to find a BOSE sound system which i retrofitted on my car, and now the sound it's much better... like 8/10
NOW the last problem that i'm facing is some background noise, which i can't explain where it came from.
It only happen when i plug in the xtrons head unit. I swapped to the original Audi HU and there is no background noise. This means the background noise is picked up / generated by the Xtrons HU.
The noise is like a continuous "buzz" plus 2-3 pops and it only appears when the unit is on pause, mute or very low volume AND ONLY WHEN I SWITCH THE IGNITION ON (NO ENGINE RUNNING), if i revers the ignition to 0 position the noise disappears.
If the engine is running the noise is there, but is very hard to hear due to the diesel engine...
This noise IS NOT a wining noise, like an alternator generated...
Anyone encounter this problem? Is there any fix?
Tomorrow i am going to replace all the Xtrons HU extension cables (audio/video in/out) with shielded cables, and if doesn't work, i'll try some ferrite(s) maybe it helps...
Thanks!

Hey,
Has anyone found solution to this annoying noise ? I have installed XTRONS unit in my audi a3 and can't get rid of it. Have tried already ground loop isolators and ferrite filters with no luck.
I've recently fitted an Xtrons PB88UNVP (MTCE_GS_V2.88_3) PX5 headunit. The speaker power is 4x45W (probably pretty standard on these things) and generally sounds good.
However, it's quieter than my previous WinCE unit and I find I have to run it higher up the volume scale for a decent listening volume.
Sometimes I like my music loud, and I can turn it up to MAX (30) without deafening myself or even experiencing clipping from the headunit's amplifier - output is still clean and undistorted. I'm running the EQ fairly flat and Loudness is set to ON.
My question is - NOT what volume should I be listening at in my car to still hear the engine, traffic around me and be safe on the roads - BUT is it safe to run these headunits at 25-30 (83-100%) continuously/for extended periods? Will it overheat or be damaged by running at this sort of volume?
Thanks
I noticed the exact same thing - again, compared to my previous WinCE units, just like you. These Android units just seem significantly less powerful in comparison. I have a feeling that the 45Wx4 max rating (I know it's not RMS) is a little on the "wishful thinking" side. My WinCE units (18->25Wx4 RMS, 50Wx4 max) seemed considerably more powerful.
I haven't seen these Android units list the RMS power, but I have a feeling it's lower than a lot of the older WinCE units. It also seems like the volume scale is just "different" - it doesn't start getting even somewhat loud until the volume is 2/3rd's of the way up or higher.
It's really hard to say if they are clipping or not in those upper ranges, but I have a feeling they may be - depending on how you have the EQ set - even if you can't hear the distortion.
To me, it seems like you have to sacrifice a lot on the audio side of things for the flexibility that you get from Android.
@jtrosky: I have noticed distortion when the EQ is set to the Rock preset, which is very bass-heavy, and is turned up high. I don't personally like heavily biased EQ profiles and would prefer to run it as flat as possible across the frequency spectrum. A little bit of tuning seems to help these units particularly though. I agree with you that their amplifiers are weak, or rather underpowered. That said, my experience so far is that at medium volumes it sounds alright, to the extent that I didn't notice my sub wasn't working at first.
So do you regularly run yours at two thirds volume or above and do you think they can handle it for a sustained period?
Has anyone ever fried one of these?
Honestly, I connected an amp shortly after installing, so I can't say how they would last over time if used at louder volumes frequently with the internal amp. To me, it seems like they have the volume control setup in a way where it doesn't get very loud until at least 2/3rd's volume - and then every click makes a substantial difference. So I wonder if they just have the volume scale "tuned" differenlty than other head-units? But my point was that the unit can be clipping without you even hearing any distortion - clipping is not always audible. I had a LOC hooked up for testing briefly and it had a "clipping" light - and I was seeing clipping way before any distortion was audible. I think these units use pretty poor quality amps.
I've actually removed the Android head-unit completely and went back to my older WinCE-based unit. Just was not happy with the Android unit (sound quality, noise-related issues, etc).

That's sad to hear. I deliberated for so long before taking the plunge and buying one. I like the Android platform, and the few niggles I have with mine aren't sufficient to make me want to change it... yet.
I must admit though, when I made my first post I had been listening to DAB, which is probably the quietest source. FM is probably 15% louder at the same volume setting, and is the loudest of all the sources. I don't know if there is any way to make this louder, as a USB device, and there is no volume 'boost' option within realzoulou's DAB-Z app (only a <= 100% setting).
FM on full whack does distort a bit, but it's too loud to listen to constantly, so while a bit weak I think the on-board amp should be capable of more.
Better control of volume on different sources within Android would be nice, do you know if this is possible?
You can alter the volume of each source in the Factory Settings, under the "Voice" tab...
If you are coming from a stock radio with stock speakers, the Android head-units may be an upgrade in terms of sound-quality. But for me, coming from an aftermarket, high-quality WinCE unit, the sound quality just wasn't up to par. The WinCE unit I'm referring to (Dynavin N7) has high-quality audio components though (4V pre-outs, "high-resolution Burr Brown 24-Bit Digital to Analogue converters", etc) - so once I got used to the sound quality of the Dynavin (or even the Rosen GM1010 befoer it), it was hard switching over to the Android unit. Believe me, I went to great lengths to make it work, but it just wasn't mean to be, considering the sound-quality downgrade and the noise-related issues I had with the Android unit.
Don't get me wrong - I liked almost everything about having full-blown Android as the OS - it's just the sound quality that I wasn't 100% happy with - which, to me, is very important.
I ordered a PX6 4 /64 GB (MTCE_CHS) head unit with 720 p display and Android 9 for my Mercedes-Benz W211. I found a seller at AliExpress with great reviews so I felt safe to order from them.
This will be a short review which I hope can help someone who is looking for info before buying a Android Head unit, but I am also very thankful if someone has ideas how I can solve my problems.
Pros:
- Very sharp display with good viewing angles.
- Reverse cam works great in good lightning conditions.
- Fast startup from standby.
- Useful equalizer which makes it possible to get a great sound experience.
- Custom ROM, root, Tasker and FCC Launcher make it possible to customize the head unit in many ways.
- Very good GPS performance when connected to original powered GPS-antenna in car.
- Apple CarPlay works and looks generally very good, but has problems with sound mixing which makes it useless.
Cons:
- Handsfree sound quality sucks so much it's useless. Sound from the other persons is bad and they can't barely hear me. Tried with external microphone also.
- No auto brightness and max brightness is low in sunny conditions.
- General audio quality, there is constant background noise and interference from wifi, bluetooth and USB devices makes it worse.
- The head unit was supposed to be plug and play but I had to modify my car and use an dremel multi tool to cut the plastic in the car, which makes it difficult to go back to original head unit. This is normal according to seller but no info before buying.
- Android apps does not display well in a car head unit. Even when adjusting dpi it is difficult to find a good setting. Text and objects will be too small or too big, sometimes frustrating and dangerous to control music and navigation apps when driving.
- Android Auto is displayed in low resolution and looks bad, it also has problems with sound mixing which makes it useless.
- FM radio reception is bad, even though I use the original powered antenna in the car.
- General sound mixing problems in different apps.
- I had dust debris inside the display, which is visible with both display off and on.
Problems:
- I have an intermittent problem with a "popping" sound and at the same time the display goes to night mode for a second and reset the clock to 0:00. Tried to disable auto night mode in factory settings but no difference.
- Sometimes when opening a door or turning on the ignition there is a loud high pitch sound from the speakers, very uncomfortable, almost hurts the ears and scares the passengers.
- Sound mixing, when using Android Auto och Apple CarPlay, it will automatically lower music volume when giving navigation directions, but will not increase volume afterwards. So when you manually increase music volume again, next time the voice will be so high it almost destroy your speakers and ears. The navigation voice in Waze Android app gets cut 0,5 - 1,0 seconds to early.
When speaking to the seller they have problems understanding my issues, and just tell me to wait for MCU update (I already have the latest). Seems like they just want to delay so the time when it is possible to open a dispute will end.
What would you recommend me to do? Demand an exchange of my head unit and canbus decoder and hope it will solve the problems? Demand a refund and buy a Sony or Kenwood Android Auto / Apple CarPlay head unit?
Just accept the problems and issues and try to forget that I paid A LOT of money for the head unit and all the accessories?
There are dozens of different manufacturers and hardware types using PX6.
Post MCU type so people can know the manufacturer and type of unit being reviewed.

Sorry, it is a MTCE_CHS, I added the info to the first post.
I think that this highlights a general problem with the chinese android head units: They just aren't "consumer-ready". Don't get me wrong, they provide fantastic bang for your buck, but they all have their problems (many of which can be solved through help from this forum) and they all lack any decent support. Having said that, I also have a PX6 4G/64G unit in my car, and I just don't have any of the problems you mention. It's not without its annoyances, and I have had to work through several problems to get it sorted, but after just a few months I am very happy with what I have ended up with. The sound quality is fantastic to my untrained ears, and it all works fairly smoothly. I got a massive upgrade in functionality in my 21 year old car for not much money.
In your case, there seem to be too many problems that appear to be related to the hardware. I don't think that an MCU update is going to fix the issues that you list, and so If it were me, I would be returned the unit asap, and trying a different manufacturer, either another chinese manufacturer or one of the proven japanese manufacturers.
