Wondering about quick-boot for android - Android Head-Units

Ok so I just bought a unbranded car head unit that support mirror link, I got an LG G2 laying around and thought of just making a android head unit, I want the lg device will go into some kind of hibernate mode so it will not run out of battery when i"m leaving the car and turning off completely, I want it to wake up fast without using too much battery like the htc devices or the one plus, is that possible?

New android Head Unit

Currently I have an avin avant 2: rockchip 3188 with 1gb.
This thing is quite slow, has no reset button and only touch buttons. I want to look into a new device and I hope you people can help me.
I have a few "demands"
1. USB front and 1 or 2 in the back
2. MicroSD (ofcourse)
3. Reset button
4. Physical buttons
5. Faster (2GB)
6. Sim card tray (not really a demand but more like would like)
The apps I run are:
Sygic
JetAudio
Radio
Spotify
Maybe more to come
I would like these apps to run snappy. Because now Sygic is extremely slow and I have to wait 5 minutes to actually use it a bit.
Are the 2GB versions that much faster? And would you say the Intel units from Joying are good or do I need a different type of cpu?
And an Europe distribution would be nice for warranty.
Hope you guys can help me with a nice unit.
I have one of the new 2gb Joying units and its snappy fast. I run Sygic also and it loads immediately. Hope this helps ...
Thanks
I am looking into the Joying UL135N2.
So you say it's snappy that's awesome.
I heard it stays on standby and does not turn off. Now is that a nice feature but how much does it drain the battery. My car sometimes stands still for a week and I do not want my battery to die. How lang will the standby laat? Do you know this?
I have my unit installed in my car I just drive back and forth to work. It has sat idle for like three days, we drive the newer car on weekends to go out, etc. I'm pretty sure it is not going to drain your battery, it acts like an iPad in that's not in use.

Eunavi 2 Din 7'' PX6 4G 64G P11 RK3399

I am thinking of buying new HU becouse my existing Hu from Hizpo PX3 7.1.2 is kinda wired, mostly because none of beetter DVR cams do not work.
So I am thinking of this one
https://www.aliexpress.com/item/32934575168.html?spm=a2g0o.cart.0.0.78b03c00oKlwsb
anyone have experience with Eunavi HU?
It's similar to the one I have, it has a few problems with my Skoda Octavia.
It boots up every time it powers up taking about 20seconds.
The canbus doesn't work with all the steering wheel buttons.
The default apps are rubbish
The theme is shocking and you can't read the text properly.
Short of the power on issue, it's not too bad.
i see.. original rom I had on hizpo px3 had similar issues, like power up it was even longer.. but with hal9k rom or "malsik" that changed.
I'm still waiting on eunavi sending me the firmware so I can have a look at fixing the problems.
It's not a problem with it booting up each time, trust me.
I have a dash which goes into standby mode and it drains the battery in about 3-5 days of not using the car for a decent drive. I'm forever having to use jumper cables on the battery. I've since installed a switch, although you can use a relay - to make it boot up every time.
I've just bought this unit btw. I'll let you know how it goes in a month. Hopefully it can be modded.
Hi, how is the unit? Have you had any chance to use rca pre outs? I want to buy an android unit but the only thing stopping me is that Subwoofer preout are either of low voltage or doesn't work at all.
The seller claims its a 5v rca pre out for the sub.. Can you confirm this?

same issue here
So I have the same unit and the same power-problem, takes long to startup every time.
Tried swapping +BATT and ACC but that didn't help the drainage.
Also, mine doesn't hold the radio presets and USB2 doesn't work.
Left a message with Ali-E. to help me with this problem.
My car is a 2011 Dacia Sandero Stepway, which is Renault, basically.

PX3 Skoda Fabia mk3 android bricked

Hi everyone,
first of all, my apologizes in advance for duplicating the thread, but I've got the feeling that the original HERE is not in the right place, and therefore I've got 0 comments since open.
Therefore, I transcribe the problem here.
After buying an android head unit for the Fabia mk3 from my wife and testing it at my workshop, I got mad because the front panel buttons were not working. I was almost giving up when I decided to install the radio anyway just to profit from the navigation by forcing us to use it only by the touchscreen, when I found out that the front panel buttons get activated only when the head unit receives the can-bus signals.
However, some days after the installation and the happiness of solving the issue, big surprise when we found the car with the battery dead. o after bringing it back to life, I removed the android radio and checked the current drainage. It was around 300mA for the car switched off. Too much for a car that is parked so long due to the COVID-19 quarantine.
After asking Google, I found out that in the new VAGs, included the Fabia mk3, there is no longer a "switched-off" power cable arriving to the radio. Only an "always-on" one. It seems that the original radio is being switched off by the can-bus signal, bringing the current drainage to a minimum. What is this minimum, I do not know as I haven't measured it.
This doesn't seem to be the case with my android radio which is sucking 300mA when turned off by the can-bus.
So I looked for a "switched-off" signal from the fuse panel and I brought it all the way up to the radio to force the total current shut-off when switching off the car.
Happy with the solution, my wife takes the car again some days after and and told me that the radio was not starting. I went to check it and I found the unit getting blocked at the "android" starting screen.
Sometimes it ends up just blocked there. Sometimes shows an alternating picture between the word "android" and a kind of arrow picture. I share here a couple of screenshots and a small video.
I've tried the reset button, even with the 15 seconds wait, and nothing happens, I get the same blocked starting screen...
Any ideas what can this be? It looks pretty damn bricked to me but I refuse to give up with the radio, it looked very well installed in the car and I was able to "taste" the capabilities right before the battery drainage and it was even sounding better than the ****ty original radio.
Here the head-unit specs:
Android 9.0 System
Capacitive Screen HD 1024*600 1080P HD Video
CPU Rockchip PX3 Cortex A9, 4 core 1.6GHz
2GB DDR3 RAM Memory
16 GB Nand Flash

EKIY D7 Android Head-unit

A few weeks ago, I decided to order an Android head-unit: I didn't wanna spend to much money, so ordered a low spec unit. After my holiday I could finally install it, and overall I'm satisfied.
Your browser is not able to display this video.
It runs on an ARM A7 1.3Ghz Quad-Core, scrolling through the screen is quick enough. Although starting apps takes a little bit longer, than used to on my smartphone. However Android Auto seems to work perfectly wired, I haven't been able to get it work wireless.
Also my original USB port of the car, doesn't seem to work with my current Xiaomi Mi 10T Lite. Which uses USB C: perhaps the USB port, is simply not supporting these new USB. My experience with the original car radio was, that this USB didn't even provide enough power to run my dashcam.
Anyway, the AlliExpress seller wasn't honest: they sold me an Android 10 headunit, but it's fake. In reality it runs on Android 8, which is okay to me. Expect than I want a part of the money back, because I wouldn't have ordered it for € 150 if I knew it's actually running Android 8.
Yes I know, it's possible that Android 10 wouldn't do these low spec headunits any good, but it's still false advertising. It seems to support sleep mode just fine, it went on instantly after I turned the car on and off. But for now I have disabled deep sleep, because I wanna avoid draining my battery.
The reverse camera is slightly titled, because of the license plate bracket. But this way, I don't need any drilling or what so ever.
I did some more testing: the screen is bright enough, even during sunny days. When connecting the phone to USB, than Android Auto will start automatically. Which is to my opinion the main feature of this Android Head-unit.
Reversing camera work, but when engine is running: there is flickering, not sure what's the cause. Perhaps the 12LED's draw to much power?
Google Maps and Spotify can work standalone together, but it's slow. So better use Android Auto, because it's safer and more stable. Also sound seems to be better, when using Android Auto. Not sure if it's because, most of the processing finds place on my phone.
The ability to change car logo is nice, and steering wheel control is very bugged. It will only allow me to assign one button? If I assign multiple buttons, than all of them have number 2. Suggesting to me, it might not see that my steering wheel control has three button's.
In order to avoid the car radio everytime deleting your contacts from the phone: go in phone bluetooth setting, and disable allow sharing of contacts. Overall when mainly using it for Android Auto, then it's a good unit. As screen isn't a TN screen.
But I feel, all Android apps including Google Maps aren't made to use directly on a head-unit. So no matter how fast your headunit is, still the integration is bad. The GPS works fine, no issue there. But there isn't a compass inside the head-unit, so it relying mainly on GPS for is position.
Not sure if HereWeGo might work better, because it has the ability to download maps. Also you don't need to run Spotify on the head-unit, it can run just like the OEM car radio play by Bluetooth.
There is a button called Bluetooth, that's where you find the handsfree and everything related to your phone. I would still however refrain from using it, especially while driving. Because it's very distracting.
That's why I already start Google maps on my phone, connect the USB and with less than 30 seconds it will automatically connect to Android Auto. Also music from Spotify would start playing automatically.
If you ask me: these head-units would be way better, if Android was striped down from all useless features.
Dispute
The dispute still is going on, I have used to different apps: both report API Level 27 which means it's running Android 8.1 instead of Android 10. I knew I was buying a low budget device, which increased in price because of chipset crisis and weak euro currency.
But Android 8 is officially not supported by Google anymore: you can still use it, no issues in that. Only I wouldn't have bought it, if I knew the Android version was fake. And obviously because of my working colleague, recommending this seller. If he didn't... I wouldn't have bought from EKIY.
Now it's a back and forth, and the seller saying the information the Fake Device Test and CPU Z give are fake instead. It's a pain in the ass, and most bugs found in this cheap device are even found in the more expensive ones.
I read, that the bug from deleting your contacts on the phone already existing for many years. People even reported it on Joying units, which makes me think. No matter a low or mid range chipset, all going have similar software bugs. It's up to you, how much you wanna spend.
Thank you for a good and detailed review.
I bought an android head unit from EKIY last month, but it is the highest spec. EKIY S7 8G+128G
I don't have any issues you mentioned in the post (lucky me).
Did you buy a general android device or it is tailored specifically for your car?
Regarding the reverse camera try different picture resolution settings. I see they are selling camera rectifiers to provide stable 12V DC if the problem persists.
https://www.aliexpress.com/item/32954917237.html?spm=a2g0o.productlist.0.0.60062e241jGhBO&algo_pvid=689c7955-2a19-4aa1-b802-97f8a8142b59&algo_exp_id=689c7955-2a19-4aa1-b802-97f8a8142b59-0&pdp_ext_f=%7B%22sku_id%22%3A%2212000018709179697%22%7D&pdp_npi=2%40dis%21AED%2133.06%2116.53%21%21%2110.91%21%21%402101e9cf16602900534683194e028f%2112000018709179697%21sea&curPageLogUid=9lfhYfopE8tz
I bought device specifically for my car, but that just means EKIY puts the universal Android head-unit in a frame matching the car. And then providing the harness...
So if I buy any other universal 9 inch Android headunit, which same type of 9 inch screen. Then it should fit as well. Device works fine for Android Auto and built-in apps, so no complaints there.
But I was cheated by the seller: it is not running Android 10, but Android 8.1 which isn't supported by Google anymore. So in a way I overpaid, because it has false specifications specifications. That's why I'm having a dispute running against EKIY, but it still hasn't been resolved.
I had to provide detailed information, so I even provided a video. Now I'm waiting for a solution, the best would be full refund without having to send back. Because I would never have bought it, when it advertise the real Android version.
Also sending back isn't a real option, so I would already be happy with a partial refund and perhaps selling the device locally. But for now I'm keeping it in the car, to use it a bit longer.
I have tried this solution for the flickering, but don't know the result yet. As I haven't started engine. When I know it worked, then I will update this post. But the 12 led camera they give for free, is really bad quality image and I believe there is no need for LEDs on a reverse camera when you have a good lens.
So I have ordered an more expensive reverse camera, from GreenYi which seems good to me. I think wider view would also befit highly when reversing, so I choose option D AHD 720P. There isn't any need for 1080p, because the display don't support this resolution anyway.
GreenYi 170° AHD 720P

Hello, can you tell me where to turn off sleep mode
Yes, you are right, the seller is a liar, the android is not 10, but 8. and he does not send me the factory firmware as a backup

Go to settings, factory settings and then you find an option called deel sleep or named slightly different. There you can put it off. But I have decided to keep it on, and now I'm observing if battery voltage doesn't drop below 12. In the last 48 hours that hasn't been the case, so I'm guessing it doesn't drain the battery.
Cold boot however is very slow: it takes 47 seconds and going from ACC to start engine will shortly switch off the device. Resulting in a second cold boot of another 47 seconds. So totally it would take about 2 mins, but when you connect the USB cable to your phone. It would automatically start Android auto. When in settings, you selected Car Link to start when usb is connected.
I filmed the boottime, you can see it's really slow. And yes don't expect any support from the seller, especially not after calling him out for cheating. Now I'm just in a big dispute and I finding it quite frustrating to be honest.
I'm regretting this purchase a little, mainly because the false Android version. Because that's something I find important as well. Basically you pay to much, when it claims to be running Android 10. No one would pay € 150 for a head-unit, running an Android version that isn't supported by Google anymore.

I'm considering Mekede this is an UIS7862 unit, and it has some support on XDA. Looks way better to me, than EKIY. But Mekede is also displaying fake Android 11, but they show the API Level 29 which is Android 10.
So not so much lying as EKIY: you can still find out the truth, if you know about API levels of Android.

The dispute is still running: AlliExpress firstly declined my evidence, so now I have made it very detailed. Seller just the whole time kept showing Android settings, claiming the Fake Device Test show false information.
I suggest half refund, but even that the seller refused. So I'm having AlliExpress step in and waiting for their solution. It's kinda a pain in the ass, but I'm hoping for a satisfied solution.

Yes, the one I bought from EKIY is UIS7862 and it shows API29 in CPU-Z. It runs fast and smooth, but I paid around 300 usd

Atleast I have an IPS screen, I mean I'm happy with the quality of the screen. I'm guessing that's a specification, which wasn't lied about.
I will keep the thread updated, about the dispute. That doesn't go so fast sadly.
I just went from my hometown to Düsseldorf: the Android Auto works really well, but using the volume button is a pain in the ass. The best is to set volume before driving, because it's hidden behind my steering wheel.
This wouldn't be an issue for British drivers, because they sit on the right. But in the Netherlands we sit on the left seat, so it's a bit more difficult to adjust volume while driving. I think this will be the same on the more expensive units.
Seller came back with: friend how you proof, your app that shows fake Android version isn't fake. Something like that she or he said.... I said the app gets information from the system, which you try to hide.
He also said, that they sell Android 10 headunits. I say yes, but the one you sold me is a fake and I wouldn't have bought it if I knew it.
Also found the option, to disable the AHD for the reverse camera. Perhaps this is the issue with the reverse camera, because it wasn't the ground wire I disconnected this morning. The reverse camera I have is definitely not AHD.....
One negative part about Android Auto, or actually the USB connection of this device: while Android Auto is running, it gets hardly any charge. So better make sure you battery isn't to empty to begin with.
The seller all of a sudden send me an update, for the EKIY D7. But when I go into the FYT Build Prop, then it's labeled as an ATOTO...
And the last line in the build prop says: ro.build.version.release=11
I'm guessing that's how they fake the Android version? In this update, which I haven't installed yet on the device. They are faking the Android version to be Android 11 making it even worse.
And in metadata, I can actually see the Android is 8.1.0
post-build=SPRD/sp7731e_1h10_native/sp7731e_1h10:8.1.0/OPM2.171019.012/19115:user/release-keys
Click to expand...

Or at least I'm guessing, this number refers to the real Android version.
I seriously don't know for which device this update was meant? But it didn't work on my update, and I was afraid that this stupid update almost brick the device. That doesn't matter if I get a full refund from AlliExpress....
But I still don't know what's the solution from AlliExpress going be.
So finally AliExpress made a decision about my dispute: from the € 150 I spend for this headunit, I'm going be getting € 30 back. Which I think is reasonable....
It's still a fully functional Android headunit, although running on Android 8.1 and basically incapable of running Google Maps straight from the head-unit. Other navigation apps might work perhaps better, but I haven't tested it anymore.
Now I'm looking into Mekede, which I guess I could open a dispute against this seller as well after receiving the FYT Based UIS7862 headunit.... because they also lie about Android version. Only they mention the correct API Level, so I already know it runs fake Android 11.
I'm guessing I will just be selling the headunit, either completely. Or I'm going be taking it out of the frame, and then order a new one. Because I would still need an Android head-unit, if I wanna keep the reverse camera.
Well I used the device in the end for three weeks, and have decided to replace it with an Mekede M500s. Which I should have gotten in the first place, but I simply made a wrong decision.
My end verdict would be: totally useable for Android Auto or Apple Carplay and listen to your FM-Radio or music etc. Not so much useable for running heavier Android apps.
I haven't found many light Android Apps? I tried Mapy.cz a Czech Google Maps, but that made the headunit crash and reboot. So in the end I haven't bother anymore, finding working navigation apps. Although I noticed for some kind of reason, they preinstall iGo navigation. Is that supposed to be some kind of light weight navigation app?
Another thing this headunit is useful for: hooking up your reverse camera, believe it or not it supports AHD. Because I switched the 12led reverse camera for an 720p AHD reverse camera and it worked.
Actually the main reason I'm still sticking with Android headunits, is because it seems the best choice if you don't have the option to get something OEM.
Ofcourse a JVC headunit could have done, but those have limited functionality: do they even support AHD reverse camera's? And what I have seen, the screens in these devices are of really bad quality. Similar to something you get for €$ 60 bucks on AliExpress.
I'm just hoping these head-units last a long time, because I read someone who had an iDoing headunit: it broke after a year. The only thing people never mention, how much it actually had been used.
@DexterMorganNL Thank you very much for detailing your experience with these scammers! I was very close to ordering an android T7 head unit from them so I'm very grateful for the warning. It's a shame they didn't punish these scammers harder but at least you go a bit of justice out of it by preventing others from giving them money.
Hello everyone.
I received the head unit three days ago for my Ford Fiesta (2011). It was easy to set-up. I haven't had time to install the rear camara yet.
There's one thing I find annoying however : everythime I start the device, it starts with Youtube? I'd like to start on the homepage. Do you know what to do ?
Hallo Dexter and everyone here. I am new in this forum and hope to find some information as well as sharing some.
Couple of weeks I have bought this exact unit for my beautiful 2004 Toyota Camry. I just to have same shape of unit in my Volvo and it was working ok I think, but that one was from different seller. I chose this model thinking for my usage will be good enough. Even though I am driving a lot and long distance I am still not living in my car. I just need some music, phone, Navi and the reversing camera is just a little bonus for safety. I have find some issues with this unit. The version of the Android is clamed to be 11.xxx but Google says it’s 8.xxx. The Apple car is little slow to connect but I can live with it. The only problem with this is that when I have my phone connected via Bluetooth the Apple car will not connect.
Still with switching it manually it would work. THE major problem is my original automatic antenna. I was controlled by the original radio. Radio on -antenna goes up, radio off- antenna goes down. With this EKIY unit the antenna still goes up and down with the unit on and off, but the unit is turned on with the engine start or ACC and turned off within 1-2 minutes after the engine off. And with this goes the antenna up and down. This is the problem especially when I want to drive through car wash line ( for example). I just can’t find a way to turn the radio off while driving or the engine running. The seller is telling me that it can’t be done and I am having trouble to believe it. And the other problem is the screen brittnes. I can’t dim it witch is enjoying by driving at night. I can turn it off but the unit goes into sleep mode. I still want to use it, but the sharp light of the screen is tiresome to eyes. I know this post is almost a year old but if anyone reads this, please help me. I don’t know much about Android but I hope there is some solution to the problems. Thank you all in advance. Best regards

Hi, I believe it can be changed in factory settings. The passcode is 3368. Or using the papier clip or pin you can reset the unit, then set up your device once more. I hope this helps

Junsun queries

Hi all, I’ve got a cheap Junsun unit in my 2008 Smart Fortwo and it’s a great piece of kit. But I have a couple of questions if anyone could help..
1- the illumination on the ‘buttons’ stops after the car is switched off and back on the next day. Which is annoying as in the dark you have no idea where the volume is!
2- when the ignition is turned on, the unit fired straight back to where it left off, assuming it’s running in the background and just in sleep mode and draining battery? Should it not completely shut down and then boot from scratch every time?
3- when it does completely shut down and reload, all the time settings have changed and needs to be set again.
Is there a secret menu somewhere that I can change these settings, or is just how this thing works?
This is a link to the unit I have..
