I've been having a strange problem with the backup camera on my JY unit (RK3066 - Malaysk ROM). I use a wireless transmitter to get the signal from the camera to the unit.
In cool weather, everything works perfectly. In hot weather, when I first start the car, I get a black screen with "no signal" until the AC has cooled down the inside of the car a little - then it works perfectly again.
At first I thought that the wireless receiver for the camera may be a little heat sensitive and doesn't work when its too hot. BUT...
The other day (it was hot again) I started the car, and it worked...perfect picture. The head unit booted and suddenly the picture turned black with "no signal".
This behavior makes me wonder if there is something in the software that turned the picture off.
Has anyone experienced something similar?

Hello,
I was having a issue where hu would out of the blue switch to backup picture and get a no signal sign and then on its own go back to normal and do this at random. Turns out the wire i was using for trigger signal and ground and voltage was not big enough. Once I replaced them its working like it should now. That is the only issue close to yours that I have had.

I have read about your problem somewhere hoping to find a hint, however, the switching back and forth works fine in my case.
Ya, I've the same problem. If the problem continues, you can use a power relay.

I have had my evo since June 4. but lately it started randomly going to the car panel. So I disabled the car panel auto launch. But the evo always thinks it is connected to a car dock. When I plug in a headset the volume is locked to a medium setting. If I use the rocker switch it has no effect on the volume even though the screen shows it going up and down. That is the main reason why I want this to be fixed so I can use headphones at the level I want. I did a full reset and when the phone restarts right into car dock. I flashed different roms and first thing car dock... This leads me to believe it is a hardware issue. There is another post but the info is limited and no solution was found. Also The hd2 had a similar problem but no real solutions were found. I would appreciate any input on how to solve or work around this... thank you
Possible work around: If bluetooth is turned on and uncheck the car dock box the volume control on the headset works

The best thing to try is to install an original Sprint EVO RUU. It should completely reset your phone to the correct settings. See if that helps. Make sure as always, you wipe everything before hand. This should let you know if it actually is something wrong with the hardware, i.e.; one of the pins on the phone connection is bent or somehow signaling to the phone that it should be in car mode.
Any word on if you got this fixed? My phone is doing the exact same thing even after a hard reset.

If i have bluetooth turned on then everything works fine... its not a fix but it seems to work for me .... and my battery life doesnt seem that much worse either
I started having this problem when I bought a cheap ass usb cable, and I was.charging on my work pc. I got a new cable, and it stopped
Sent from the bowels of my mind....
BUMP BUMP! Wake up thread! I'm having the problem too!
My rooted EVO 4G running baked snack 1.8 is having the following issues, and they seem related as they started happening at the same time:
Cannot change headset volume (when volume rocker is pressed, graphical slider moves, but audio stuck at a low-to-medium level)
Car Mode launches sporadically without reason, even when phone is locked (had to turn off "auto launch" to stop it from popping up...it's as if the phone thinks it's being plugged into a car dock, which I don't own)
When sending/receiving a call, the external speaker turns on, I have to shut it off each time I answer a call (SO DAMN ANNOYING):
SOME MORE INFO:
This all started happening at once while I was walking down the road listening to music on my phone (i.e., no software was downloaded/changed)
I have done a nand restore to a previous point where there were no problems and the issue persists
It's not because of baked snack. This happened to me once before when I was running the stock ROM, but one day it just suddenly fixed itself. But it's been weeks and I'm tired of it.
ANY IDEAS??

Im pretty sure it was the charger i was using just like the other post said. I got a dock charger and after a week or so the problem just stopped. Im not sure if something is getting bent or shorted or what. Try turning on bluetooth for a work around until the charger straitens things out
No headphone volume/InCar App starts...solved
Have owned the HTC EVO 4G about 18 months with no problems. These issues just started happening yesterday out of the blue.
What didn't work:
cleaned charging port w/toothbrush
toggled bluetooth settings (don't use bluetooth)
Restart
HTC update
PRL update
What did work:
Uninstalling Vlingo
-Peace Out
I have some questions. (Copy from the old thread)
1. I mean that i read it here, but I'm not sure. At the moment I have very often the bug, that the volume button not works. Mute works, but louder and quieter not. I don't know when it doesn't work, but after a while no function.
2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?
3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction. After a minuten the radio shows the bootlogo and have a loop. So i have start the radio new with reset or power off from the car.
4. Since a few days if i turn off the key normally all lights form the radio and display shut down. Additionally board computer shut down too after a few seconds. Now the light from the dvd tray is on and board computer too (after a lock from the car too). I dont know why but I don't know if that is so good (Battery).
All this errors are since a few days. I tried to do any settings but the problem is always here. Does anyone no about that? I think it's an app, but I don't know which one. The last chance (if I get no solutions) is to install another rom? That is really crazy, because it's only since a few days. The days before it works perfect.
I have JY 2.73 with the Malaysk Rom from September (1024).
Thanks
Update: Now i installed 2.59 JY and tried again. WiFi will always gone with no bars. So i turn off and turn on again. At the most cases it works. But the problem is here again. The same with the touchscreen crash. 3G doesn't work. always no bars.
So the previous MCU doesn't work again. Maybe a software error.
Could you please try to measure the voltage alignedto the HU while you encounter those problems? I rellay mean at the radio side (so not at the battery poles).
Such issues could be lack of voltage. If not and flashing does not solve it could be a defective unit.
Just to ensure: You flashed Firmware AND MCU? AM I right wit this assumption?
If not: Try to flash a new ROM first (probably try Malaysk ROM)
Btw: Moved to Q&A

Thx for answer. How can i measure that? Do you know which cable it is? And if the cable shows not the 12V? What can i do to fix the problem?
Sure. I have Malaysk Rom and the MCU JY 2.59.
you would have to get amulti- or vooltmeter and attach that between plus and ground pins at your HU.
If you don't know how you should eigther try to follow another way first if possible or ask someone to do it for you (it's electrics)

Thanks. I ordered a multilmeter. Maybe it's the battery. At the moment the car works really hard if I start it. The radio takes so much battery but the radio is off. So that can be the problem.
low voltage can cause many weird problems but you have to know a new battery might not solve your problem!
If you have low voltag while the engine is ruunning then you have a different problem. eighter there is a connection issue somewhere on the path the energy takes from battery and generator to the HU or your generator might have a problem. But that is open to check when we know if it really is a voltage issue.
Hi,
i'd like to give you an update for my problems. Since the last days I have the problems, that my car didn't start. Now we see, that the battery is nine years old. Now I charged the battery (tomorrow I'll get a new battery) and the first test shows WiFi works for 3 minutes. I know - that's not a lot, but I only can try if I have the new battery. 3G doesn't work - always the same. But that's not so important for now.
At the moment I don't have the volume error. I will test it, If i have a longer car drive.
The problem with the touchscreen is actually. Since a few time, after few minutes the touchscreen is bricked and I see the points that i touch it, but I can't click anything. If I touch ten times, twenty times or often then radio shut down and shows the boot logo... forever... it doesn't boot again. So I have to make a hard reset.
And the last point with the light board computer and the light dvd slot after plug off the key is actually too. It don't shutdown the lights on the standby time from 10 minutes (set it to 10 minutes). I know now, that I can shutdown it completely if I press the volume button for 3 seconds. Than it's turn off. So it's a setting problem from the firmware?
Today I plug in the key - nothing. Radio doesn't start. So I looked behind the radio and saw, that one thin cable is not in the wiring harness and I can see the wires on the cable. So I tried to put it in the wiring harness again. I hope it works longer now. I wrote carjoying and ask for a new wiring harness. Maybe all problems will be fixed, If i have a new.
Hello again,
now I've got a solution for the wifi problem. I've tried to connected wifi - i Known that doesn't work only few seconds and after a few seconds it shows 0 bars on wifi... now I disconnected my 3g stick and LOOK it works... full bars, no losing connection. I connect 3g again and the same problem after a few seconds.
So th3 3g stick (E1750 from Huawei) makes some problem OR the usb cable?
Huawei E355 also not working. Same connection problems with malaysk rom MTCD
Any suggestions?
Ok, I installed the new Joying 10.1" VW head unit in my car the other day, and it's working pretty good, however I'm having a couple of issues. I installed Malaysk's ROM onto it and still working through setting everything up the way I want it, but I'm having 2 issues I can't figure out, and they are driving me nuts.
Wifi: Whenever the unit reboots, the WiFi is disabled. I have to manually re-enable it every time.
12-Hour Time: Every time the unit reboots, the time reverts back to 24-hour time.
Anyone know what I can do to fix these issues? Getting rather annoying having to switch them every time the unit boots up.
Thanks

Sounds like the 12+ and ACC connections are swapped.
Thanks for the reply, but the unit is switched on Via Can-Bus. There is no ACC wire. It powers on and off just fine when I start and shut off the car.

Then your 12+ is not constant.
Yep it is, verified with a volt meter, 12volt constant stays hot, even went out and checked after my car had been off for over an hour just to make sure... I shouldn't have said there is no ACC wire, ACC is supplied by the Can-Bus adapter.
As far as the wiring goes, I'm confident all of that is wired correctly. I used to install car stereos as a job for 5 years, and this is the 3rd head unit in this vehicle. I'm an Android enthusiast, and definitely know my way around the system, even though this is my 1st Android head unit I've dealt with.
The 12-Hour time issue was happening before I installed the ROM on it, but the WiFi issue didn't start until after I installed the ROM.
Ok, thats a puzzler then. My observations have been that wi-fi will turn off and 24 hour set every time power is lost on the 12+ line. It seems independent of rom used, would happen on the stock rom and on a older version of Malaysk's I'm currently using.
Well, for whatever reason today the settings never reverted back. I don't remember changing anything, but I did go through every single menu and sub menu in the settings section. Oh well, fingers crossed everything stays set, because this head unit is perfect for me now!
I have the same issue + no bluetooth. I have a YINUO 1024x600 Quad-Core RK3188 and it's doing the WIFI OFF, 24 HR, NO BT.
Hi,
So I had the razer phone for a week now and wondering if anyone has experienced or fixed two things:
1) Is quick charging always on?
I can't find any setting for it and I charge at night so I don't need quick charge unless it's an emergency.
2) When using headphones, Google music and YouTube will pause and start playing randomly. I would of thought maybe a unstable internet connection might be the case but even my downloaded music does it as well.
If anyone has solutions or can confirm they have the same issues, would be greatly appreciated.
I have had a similar issue as well. I use slingbox heavily, and when using my Verizon 4g sim for Data only, and Wi-Fi enabled I would see a random Grey (looks like a blank message prompt) blurp appear at the bottom, center of my screen. It would cause my Slingbox app to lose connection and close the video. Once i removed the Sim card from the phone, and use it in Wi-Fi only mode, I do not get the problem. I thought I would share my similar story.
Cheers.
Well, if anyone else is getting the random pausing and playing, I have narrowed down the issue to the USB audio dongle having some wiggle room when plugged in (IE standing or sitting still = no problems but if you're moving, you have a good chance of the dongle wiggling around and causing disconnects and reconnects which is why it pauses and plays).

No I am not. I did not have the phone connected to a charger when i encountered this problem. I came across it when i was doing battery test. I crank the brightness up, and stream my slingbox to see how long they can go. When my slingbox kept dropping connection, but not displaying a network error I started to take more notice of the issue. Once I was able to catch the problem in the act, I saw this random grey window appear at the bottom center of my screen. Slingbox drops the video, and goes back to the main login screen. The amount of time between disconnecting was also random. Sometimes it would disconnect almost right away, other times it would stay connected upto 15 minutes before dropping.
Once I remove the Sim and use Wi-Fi only, there is no issue.
Cheers.

I am in the same situation. With my CDMA/UMTS/LTE sim card I do get a data connection but I have frequent data drop offs. I'd see LTE, one minute then half signal with 3G then no signal at all. Even with cellular data off and only on wifi i would also experience drop offs of from the wifi also. It would even drop my magic jack calls only on home wifi as soon as the other person answered. Took the sim card out and I have no issues.
I think he was asking if you were trolling because we are off topic in that we do not have GSM carriers.

Hi. I did not find it by search, but can anyone come across it.
Oneplus 3 - wifi and bluetooth problem. After opening the phone, to replace the power cable, it became bad to catch wifi. Only if near. It is worth moving back 4-5 meters, then the signal disappears and switches to the cellular one. Bluetooth only works very close, 10-15cm. If further, it is immediately interrupted.
On the Internet, I found topics for the same problem. It all started after the autopsy. Who changed the camera, who changed the battery and the result is the same. I still haven't found a solution ... ((((((
I would be very grateful for a hint!
Hi,
Have you resolved this issue? I also have this problem after replacing rockers.

Hello. Upon careful examination under a magnifying glass, I found a downed SMD component in the indicated area in the photo. I don't know if it's a resistor or a capacitor. So I just soldered it directly. And everything began to work as before. The signal to the WIFI chip, which is hidden under the cover, should pass along the path indicated in blue. The contacts of the WIFI antenna are marked in green. Next, you also need to check the components.
