Hey everyone,
I'm experiencing an odd bootloop on my Joying Sofia unit. It started happening after I hit a small bump in the road- after I hit the bump, the unit went into the reverse camera screen, which is odd because I don't have a reverse camera hooked up; the signal is not connected to anything and was taped up. So I just saw a black screen with the yellow back-up camera lines. It stayed on this screen even after I restarted my car at a stop light. I had somewhere to be, so I turned my car off and left for an hour or so. When I returned, that's when the boot loop behavior began. Most of the time, midway through the splash screen, the unit will reboot- this happens several more times before it gets past the initial splash screen and moves to the animated android loading screen. After this screen, I get to the white "android is starting" box (my unit is running the GTX rom) and then the screen just turns black suddenly. What's odd is that I can still control the screen, and I can see the screen for a split-second as I hit the reset button on the front of the unit. Furthermore, it seems like my USB headers are not getting any power- my 5V fan doesn't spin when connected, and I don't see the read/write lights on my thumb drive when I connect it either.
I've tried to capture the behavior in this video. Any help or guidance is greatly appreciated. I purchased my unit at the start of October in 2017, so I've just passed the two year warranty

Hello XDA members,
I have been following XDA for almost a decade and now came my time to ask for a help.
I bought few months ago XTRONS D717AL. First of all, great player, awesome radio tuner. Catches many stations I couldn't with my old Audiovox and Clarion. It comes With Adroid 5.1.1 and Intel chip. Model number says: Full AOSP on Sofia. MCU Ver: HY_SFY170224EF.
But since day one I noticed a weird display actions. Radio starts right after I start the car engine, display pops-up and on random basis, sometimes the display lights up, sometimes not. It takes about 20sec to load the OS and apparently, the touch screen is working. I know where the Quick settings are, if I pull the top navigation panel down when the screen is in a working state. There is a Light button, which enlights or darkens the screen.
In a dark state (blank), if a pull the navigation panel down when the screen is dark and press the Screen button, screen enlights. I know approximately where this Light button is and pressing it screen enlights. That makes me think, that the screen darkness goes to value 0 at some point before even the OS load.
I have rear camera and DVR attached, but since I took everything away today except the ISO wiring harness, it makes me think that these AV in signals are not the issue. I even took away the reverse camera control cable, illumination cable, and GPS antenna. Brake In cable is fine attached.
Last week I tried to factory reset the unit – no luck.
Flashed with a firmware from the Xtrons tech support – no luck.
I recorded a video today which I uploaded on youtube (I can't post links yet, too young to do that )
Search "XTRONS D717AL Screen Problem".
If anybody ran into such a problem and a solution, will be much appreciated to share here.
Many thanks.
Edit: I just noticed, that upon switching off the radio, the dark display flashes for a half second on its way going in. Possible display cable issue?

I have never tried to go to recovery of this unit. But, I found another topic here:
https://forum.xda-developers.com/an...button-combination-to-enter-recovery-t3391682
Regarding my problem, I returned the unit and it was replaced with a new one since it is still in warranty period.
Hi guys,. I own a a-sure 5.1.1 on a opel canbus. The past month I’ve had a temperamental black screen issue. It goes blank but touch still works. When it goes blank it takes a few days (engine starts) for it to come back on. Then it works fine for 5mins or a week,. It’s not been software updated since I’ve owned it (5yrs). Hard reset doesn’t solve the screen. But it has helped in the past.
I’m not to sure,. But I think my car heaters are encouraging the blank screen (heat)
I’ve stripped the stereo and rebuilt it (ribbons/wires).. put the stereo back in the car and the screen was still blank. I not used the car Sunday.. but today Monday the screen is working all day. I checked it on all work breaks.
Any suggestions?
First of all, your question is not related at all to Android Auto.
Second, it looks to me more as a hardware problem, like a loose contact of the display. I had a similar problem with a Blaupunkt car radio with a detachable panel. One day the lcd display went black and never came back, but the radio and all its functions continued to work fine.

Hi everyone.
I have an Android 10, topway unit that works perfectly except...the screen is unresponsive without a reboot.
So I turn the car off. Screen goes black. - check
Put the key in, turn ignition, the screen comes on but not as my regular loading screen. The app icons are large and spread out in a couple of lines. Touchscreen isn't responding. - rubbish!
Put a paperclip in the whole. Reboots. Looks great. Works great. Aminor niggle I know but anyway of avoiding the paperclip reset?
I've tried making sure wiring is correct. Awaiting seller for more details on unit, firmware etc.
Wondered if anyone slightly more auto-minded would know the solution.
Cheers
Is it possible that the permanent on and switch on wires are round the wrong way.
I did do yellow to yellow red to red.
As described in the title, the last year i've bought a Chinese Android Head unit, already after a couple of days after buying it, the unit, after some drive, started tuning off and on repeatedly (just the screen and audio) and the only solution was turning off and on the car so that the unit would reboot. Surprisingly the issue stopped happening after a couple of times, my thoughts was that the system was trying to updated some drivers or something like that, but now after a year, the issue appeared again and after about 30/40 minutes the issue stopped, without rebooting the unit. Then the issue appeared again while on a trip, and even after 1 hour the issue was still there, and when i turned off the car, the unit didn't turn off as it should when removing the key from the ignition, but surprisingly, the issue was gone! When i turned on the engine again, all the canbus functions where gone, opened doors, clima control info and other data from the car weren't showing anymore, but the issue was gone, also the touch buttons backlight wasn't turning on.
In order to turn off the unit, i have removed the fuse, when the unit rebooted again everything come back to normal. To better understand the issue, i attached a video.

Check your yellow, red, or black wire. I got a similar problem
I am having a similar problem. Mine turns off when you start the car. I checked the red and yellow but they both have power. Turned off it works great.
Hello,
i have Dasaita PX6 7" without hardware buttons and some time ago the touchscreen started to do strange things like i'm driving and i hear the media makes *bop* sound as if i've touched the power touch-button and the screen goes off or it launches a program as if i've touched the screen over where it's icon is.
Now it seems it stopped doing all this but a portion of the screen is just not working, not responding to touch.
The pic of the unit is from the web but mine is the same. I did the color rectangular areas tho to show and say - the green area is responding to touch, the red area is not responding
I write for over a week to Dasaita on Aliexpress where i bought the unit for solution or for new screen - they just read, no answer. I also write to their FB page - no answer.
Because the portion of screen which is not active i can't drag and drop icons from other screens to main screen - i have mouse, but i cant select and drag. Any suggestions?
And please tell me if i can fix this touchscreen (maybe it delaminated somewhere and its not making contact) or where i can get new (because of high chance to ruin this when trying to fix it).
Thank you
Have you ever recalibrated the touch screen?
I don´t know how it works on yours, but for a couple of units it works like all 5 fingers touch at the same time and hold it until you get a marker on the upper left screen.
Touch it as exact as possible and do that for all corners as you get the touch point visible.
For the buttons on the left side you should have a setup in the settings menu.
Hi, i watched videos about the 5 fingers touch but it doesnt activate on mine.
I entered the factory menu /with the 126 password/ where are similar functions and tried them several times just to be sure - no change.
The buttons on the left side are part of the touchscreen even tho they are on the black stripe, its jsut painted, it dosn't matter.
BR
In this case you should get in contact with Dasaita and/or the seller.
May be there is an issue with the controller or firmware.
