HU strange behavior - MTCD Android Head Units Q&A

Hello XDA
After changing my HU to another XTRONS (PX5, 4GB, Octacore, Android 8, MCU GS 3.00) and installing it in my car i thought that everything was perfect.
I tested before installing it in place, just in case, for more than 1 hour and it was perfect. After that put it in place and well... 2 minutes later it rebooted by itself (ok, that can happen). After it rebooted i proceded to install my GPS app and the maps and testing it. The moment i entered the app (Sygic) the screen went black but sound was still playing normal (radio/music). Took the radio out again and looked to see if the conectors were ok and they were. After rebooting again i installed more apps/games/heavy benchmarks to see if it was a GPU or CPU problem and i couldn't make it happen again for the next hour. So i thought of updating my apps through Play Store since it was everything ok. Started updating google maps, youtube, etc. and in the middle of one of the updates the screen became a flicker fest with white lines horizontaly and a few seconds later black again. This time no radio, no touch, no screen., nothing.
My question is, before sending it back, if that's a problem with temps or maybe another problem? I opened the HU (seller gave me permission because he thought it was the "core board" loose as he stated per email), took the board out and checked again and pressed it pretty good. I also checked the display cables and took them out and in again. Today i drove the entire day without problems but i only used the radio and music app and the i-bus app as i have an E46. Having regrets already because my old Allwinner unit was slow but perfect.
Happened to anyone or does anyone has anything to add? Heres a video of what happened the day i installed the Head unit.

Fuze screen problems

Today I used the iGo8 GPS for a little bit just to get onto the freeway. The phone tends to go to sleep, and when that happens, it loses it's GPS signal. Since I was already on the freeway, I know my way around so I just let my phone sleep.
When I got home, I realized the bottom part of the screen, where you can scroll through home, people, messages, etc. is messed up. That part of the screen keeps flashing. AND the GPS screen got burnt into the screen, like how things burn into Plasma Screen TVs when you leave it there for a long time. But it's not a completely burn on, it is like a ghost affect.
I have soft resetted my phone. Doesn't work.
Anyone knows how to fix this problem?
Thanks.
I can post pictures/video if it will help.
Have you tried running igo again and closing it down properly?
Yeah, I closed igo properly. It's not just burnt in the igo screen new. It changes. Now it's the Today page. I can see the "Phone" and "Camera" buttons burnt into the lower part of the screen.
ROM Issue?
What ROM are you using? I always use EnergyROM and its a great ROM but it always does the same thing... i thought my phone was ruined the first time i saw this, but when i flashed to another ROM it all went away, im not sure if certain ROMs use different video drivers or what, but my problem atleast seems to just be with the ROM.
Good Luck!
use a all-black or all-white image(i think all black is betteR) and keep it on to try to reduce the burn it...
ohhh. I am using EnergyRom as well. I will change roms and see what's up.
the all black image seems to be a good idea.

[Q] THL W8S Issue - Lock Up, Screen Fade, Auto-Reboot

Received this phone (THL W8S) 5 days ago, and straight out of the box it has had a serious issue where the phone will lock up, the screen will fade slowly to black, and then reboot itself. The problem occurs both after factory resetting AND in safe mode.
The phone is unrooted and running the stock ROM.
Basically during use, the screen suddenly becomes unresponsive to touch and the physical buttons (home, volume, power) all stop functioning. As soon as the phone locks up this way, the screen slowly fades to black over about 60 seconds, at which point I have to leave it to fade completely before it reboots itself.
It happens most frequently when using any browser (stock, or otherwise) taking from less than 5 seconds to around 5min before the random lock up occurs) but also happens when scrolling through messages; scrolling through emails in either of the stock apps; using a compass app which came pre-installed (very quickly).
Initially I thought it might have to do with WiFi, but problem also cropped up with WiFi off, using 2/3G. Then in troubleshooting also managed to get it to happen using the camera (lot of motion, and repeatedly taking snaps).
Also odd is that the batteries I received in the box were generic black ones, not the official stamped/logo'ed THL ones I've seen on every website and every unboxing of this particular phone. So while there's a possibility this may be a battery issue, the fact that the phone hasn't done this while using a more battery draining app (Beach Buggy Blitz; Rayman Jungle Run) makes me think this is a deeper hardware fault related to , although I don't know enough about voltages and such to rule it out completely.
I have a couple videos showing the problem, but unfortunately I'm not allowed to put the links here. Should both be easily found by searching:

System Unresponsive with 5.1 Stock Rooted

Anyone having the same issue and have found a solution?
Phone suddenly stuck at some instances even with non-extensive usage.
Yesterday I was only using Facebook app. When messenger bubble pop up, my phone suddenly spiked. Moved once and then it got stuck already. You'll notice that it's not Facebook app only that's not functioning since nav. buttons are also stuck. You can't go press home and clear recent apps/hibernate apps. Power and volume buttons are also not functional.
So I assume the main system crashed. I only did a long press on power button to restart.
I installed Franco kernel r73, and thought that issue would only occur with stock kernel.
However, it occurred again today, I was viewing photos in Stock Photos app. I haven't started viewing the first 10 images yet, so memory should not be consuming that much. I turned on the auto rotate to view the image larger. When I turned the phone landscape, it reacted like it's about to rotate. And suddenly it got stuck. This time, power button is functional. It turns the screen on and off but it still turns to the same stuck screen, not the lock screen.
I've been experiencing this since 5.0.1. and almost everyday since I updated to 5.1.
I'm not sure if this is a hardware issue on my unit since mine is already about 1 year and a half old. I don't want to buy another phone yet!
Or is this a common issue nowadays due to Lollipop upgrade. If so, then could you provide temporary fix before they update this on 5.1.1.
Thanks a lot!
I had something similar . When I put forward the curtain hangs notice and then everything worked fine
Meh
I've seen this behavior on my Nexus 5 only on 5.1, and I'm pretty sure, it was introduced with that specific lollibug version. It's really annoying, that you have to reboot the phone every two or three days to avoid the freezes.
There's already in issue for that, it has got the ID 161032.

Crackling Audio Problem

Non-rooted. Not dropped. No water exposure. Since day one.
I have had issues with my sound on my S6. Audio played through the main speaker has a crackling sound whenever audio is played with the SCREEN ON. This applies to videos, music in any app, but NOT when a call is on speaker phone. If I turn the screen off while listening to music, no crackle. Right when I turn the screen back on, crackle. Haven't downloaded any audio equalizers or anything like that. Everything is stock. Tried a reset, a reboot and a cache clear.
I haven't had time to take it into a Verizon store but will before the 14 days is up if no body is able to help.
Thanks in advance.
Did you figure out what the issue was? This is still happening to me!

I have the same problem with my AT&T S6 Active. The issue shows about 30% of the time, yesterday even while playing Clash of Clans, so it can't be the settings, I'm prone to think it's a driver issues. I also experience problems with the camera where if I haven't used it in a while it will shake, trying to image stabilize for around 3-5 seconds. Another issue I have is with trying to get the screen on, sometimes I will have to push the ON button 5-6 times before the screen comes on long enough for me to swipe my unlock pattern. After having owned a S2 and S4 Active I gotta say I'm extremely disappointed with Samsung. Without even getting into the whole No Removable SD card slot argument. My next phone will be a Nexus.

This issue stopped for me a couple weeks ago after the latest update which includes the application optimization/battery saver. After this the problem stopped, so I am assuming the upgrade ended it, or one of the apps that is now "optimized" was the cause of the problem.

Unfortunately the new update to Android 5.1.1 which I applied 2 weeks ago did not stop it for me. Just the day before yesterday the crackling even happened why my phone played the Alarm Clock tune I had set. It's gotta be a driver problem if it's happening on the Alarm Clock, or maybe even a faulty speaker but it's not happening all the time. Anyway, for this and a lot of other reasons I decided to part way with Samsung on my next phone.
Hi
I have the same problem. Any solution?!
So I ended up calling Samsung about this because it has been driving me nuts. We have narrowed it down to it being third party apps. Having said that, it could also be the setting under display causing the third party apps to malfunction. I went to settings>display> changed from adaptive you AMOLED cinema. I also removed most 3rd party apps from my phone that I downloaded in the past week. I haven't had the issue come back yet. Fingers crossed!
This is a display issue. Go to settings, display, change screen mode to anything BUT adaptive. Adaptive screen mode is not compatible with many 3rd party apps. Hope this helps!

Any 10.1" PX5 without Google Maps sound problems?

Does anybody know of a 10.1" PX5 HU and/or system software, in which the spoken output from Google Maps is ok? By this I mean, the sound doesn't stutter and it isn't delayed. I have a couple of 7" units, the original software stuttered badly, and the newer software delays the Maps spoken output so it gives directions after the turn has already passed. Currently I'm using a Joying 10.1" and Maps occasionally creates incorrect colored striped regions plus today it rebooted. Since Malaysk removed Google Maps I assume he wouldn't be interested in fixing this issue. To be fair I should state I'm still experimenting to find a way around this, but I've had the same problem with 4 units, since before the Android 6 updates. I've attached a picture of the bug, the white and smaller pink areas are incorrect. The wavy lines are a figment of the camera, what I'm referring to is the right and top mostly solid white areas. I've been in touch with Joying but no progress.
The latest MCU and updates have addressed the stuttering audio for me. I'm still getting random freezes and crashes though.
Yea I have a witson head unit and maps is horrid now, when I first got it 6 mo ago it was ok only did it occasionally, but now its terrible and unusable 99% of the time, forget about trying to listen to music or anything when running very disappointed. I am running the latest sw and fw as of today 7/27/2017
google fixed the maps this mornin. update the app. much better
