Hallo,
today i got my Desktop Dock. So i thought tell you how it worked.
First it looks vary nice on my desk. But the first issue i head is the Audio output. The only way i got it to work is by installing the Home Dock App. With the app it worked nice. But the sound is vary bad when the Charger is plugged in. I think they did not put any shielding in so the charging is interfering with the audio signal...
An other problem is the lock screen, I use the nice dot connecting one, it activates after the timeout an when starting a app i have to input the code for the app to start, vary annoying...
Thats all i noticed for now.
ps: If you noticed the same problems and got a solution please tell me.
In my case i cannot get audio output at all. Don't know but maybe it has something to do with voodoo sound. I use that Desk-app too. Strange, have to investigate ...
I have an xt1033 16GB Dual SIM Moto G. One day, it suddenly starting making strange high pitch noises (while on stand by).
Pressing volume up/down to get the phone to make the confirmation sounds sometime helped, or sometimes the issue disappeared after a restart.
However, in a few days, it got more and more often. The phone would either make high pitch noises or not make any sound at all.
Nothing related to sound worked any more.
So not even the camera, or watching a video on youtube or recorded by the camera. (This video cannot be played).
Of course calling also doesn't work.
I am wondering if maybe there will be some driver errors in the log ? But I don't know how to see the log.
What I tried so far:
- changed to a different ROM and/or resetted to factory defaults to eliminate any software issues.
- changed the 2 speakers
- removed the top right screw (this helped a lot, sometimes pressing and depressing that area made the phone to work). This last step seems to indicate the issue is related to something being loose, a cold contact somewhere on the motherboard. I inspected the motherboard but can't see a lot since the various chips are covered with metal.
Maybe the audio chip has a problem?
Any ideas? If I remove the screws now, play with the phone a bit and put it back except the top right screw it will probably work again for a few hours or days.
But maybe when the issue comes back, something is recorded in the log, like on a PC when you remove a hardware device?
Thank you!
Hi,
I use the S40 rugged phone from Caterpillar as I break my ''normal'' phones over and over.
I'm very happy about my new aquisition and its roughness has been tested already (dropped it a few times from 4 feet: nothing apart from a few scratches on the aluminium casing and some scratches on the glass protection sheet).
Even watertightness was tested when kayaking (bag was full of water so phone was immersed in seawater or 2 hours approx) only headset was bugging : phone recognised a headset device while there was none connected, but that was fixed after a quick cleaning with cotton buds and alcohol. The rubber cover of the headset is not closing well so it's a fabrication weak spot.
My problem with the CAT S40 (maybe same on previous models) are two issues:
- 1. When plugging headphones, I can hear the conversation, but the phone's microphone stops working. Tried a headset with microphone but here too no mike...i can hear, the others don't hear me. ,??? Anyone ?
- 2. Annoying when making a phonecall: after having dialed a few numbers without problem, the next contact is selected. For some reason phone starts the call, but the sim card selector does not appear (it's like it's hidden behind other applications).
When hitting the return button and selecting once more same (or another contact) the phone opens a slidescreen asking to "return to call in progress".
When doing so, you find the ''select sim'' pop-up window, but can't cancel the call option.
Sometimes it starts calling, and you can't access the active phonecall, blocking you from hanging up, or even see who you're finally calling...
Very annoying! Anyone had this issue already ?
For now, I reboot the phone each time this happens, but I don't have time for this sh*t when working, so I really would appreciate a solution...
Cheers and thanks for your support

OK here goes - if someone could help I'd really appreicate it...
Galaxy S7 Edge - light drop resulted in smashed screen. Did a screen/frame replacement myself... which worked a treat.
However have noticed that the loudspeaker now no longer works... So no ringtone, music on media play or alarm etc. Also did the *#o*# speaker test - again no sound on speaker (Receiver test on internal speaker is fine)... just the main external loudspeaker which has packed up.
Wondered if I'd blown/damaged during my screen install/phone drop - so I bought a new loudspeaker - but to no avail, still no sound.
So then I checked both my original & the freshly bought new speaker in both a multimeter and via hooking them up to another phone - BOTH UNITS WORKED! - So at least I know that the speaker units that I'm using are both fine. But put either back into my phone and no sound! ARRRGHHH
Have flashed (via Odin) G935FXXU1BPLB_G935FBTU1BPK3_BTU (v6.0.1 UK) - again no sound. Have additionally since let phone auto-update to 7.0 via OTA update - but again still no sound.
All other functions on phone are perfect (including listening to media/music via headphones).
Looking on web, I see a few people experiencing no sound since screen replacement and or flashing and I have tried the host of suggestions offered - everything from pause music and reboot, reboot with headphones in/out, toggle Power Save mode on/off, toggle Bluetooth on/off, clean out the headphone jack (sound works fine coming through headphone jack BTW just main speaker that wont play anything) and ensured speaker pads are definately contacting the mainboard pins etc.
The only thing I've not been able to yet try is "Emergency Software Recovery and initialization" via Smart Switch as Smart Switch simply freezes whenever I select this option (no follow up pop up window) - though phone is recogniosed.
Anyone else expericence this kind of no sound issue? or know of a sensible (cheap!) solution.
Regards
Mike
Think I've managed to find problem myself - if not solved it... sadly.
Used an old loudspeaker from a long since unused phone - soldered up a couple of wires to the terminals for ease of handling and turned on my phone - ran the speaker test (*#0*#) so continuous sound playing (if not heard!)... touching the wires from the bodged loudspeaker on the main PCB mainboard terminals got nothing, though then grounding one wire elsewhere and hey presto - sound once more from my phone!
So looking like a cold solder on the main PCB mainboard!... Reflowing is beyond me, so I now need to hunt around for a decent company who do PCB repairs!
Not quite the 'Have you tried wiping the cache' fix I was hoping for unfortunately... Not sure if PCB damaged in the drop or in the screen repair - but thought would post findings in case someone with exact same circumstances etc.
Regards
Mike
I have a MTCD/MTCE head unit from Witson(MX) and i'm using the latest Malaysk rom and Mcu(1.75) for my unit.
I can hear a low pitched static noise from speakers when car is silent. It's not loud, but i can hear it. I just realised source of this static is LCD screen. If I decrease brightness of LCD or completely shutdown LCD the static noise came from speaker stops. The sound is even changing with respect to colors on LCD.
My question is: I don't want to return my unit. Can someone with technical knowledge say me how can i solve this problem? Should i install some kind of filter on speaker cables? Should i ground case of the unit or Lcd?
I have the same noise, I didn’t do anything about it because I never have a situation without listening to something. When I drive it’s impossible to hear it.

Interesting. I have the same noise but haven’t figured out what causes it. I’ll check your LCD theory tomorrow.
a) I have PCB mounted quadlock (VW) on rear of HU
b) i have factory fitted amp in skoda superb ii (VW quadlock - not RCAs used)
c) with aftermarket HU, the amp is turned on when the key is in ignition position and not controlled by canbus like with original
** this is have a very faint hiss from the unbalanced line input being on without a source, but is not the noise we are referring to here **
d) noise is not present if i put back Chinese WinCE HU or original RNS315
e) there is no noise during initial boot screen, or car logo or even during loading of Car Loader AG (inc with HA rom) from cold boot
f) shortly after the Loader screen, the +/- volume keys become active - this is when the noise starts (motor running or not - the noise is the same)
g) if you put the car in reverse prior to turning on, you see white lines about 1cm apart before the vol +/- is activated.
h) once the volume is activated, the noise includes a clicking of about 150-180 bpm (the white lines on the reverse camera flicker to this beat as well)
i) using factory settings/touch keys to config pwr key for short press screen off / long press pwr off and the screen off does not affect noise.
j) changing the factory settings/other/amp gain from 0 to -12db or -15db lowers the noise gain but requires increase volume to overcome the noise.
k) the noise varies and fluctuates with changes in the menu e.g. scrolling and display e.g. download % counter changes
l) the noise varies and fluctuates with touches to the touch screen
m) the noise does not change in amplitude with changes to the system volume control
I have seen a thread where it is suggested, that the interference is coming from the LCD screen and can be verified by turning the screen off - see g) above
** the other thing i am suspicious about is the grounding. I am connected through Quadlock, but trying to power via the Quadlock on a bench doesn't work. Only via
the white connector with the RCAs. says to me something funny going on with either the power or ground wiring. **
Based on all the above, it seems fairly clear that the issue is either the LCD/CPU or some other RF component inducing the noise into the system. i.e. design fault.
I don't have an oscilloscope so can't probe if the noise is on the LCD cables or being induced by the screen RFI without shielding.
Simple test might be to remove the front screen (while still plugged in) and extend the cable moving the screen as far as possible, possible place a metal sheet behind the screen and in front of the unit, to see if the noise changes.. That would at least tell if it is a shielding problem with the screen.
i am surprised there is no solution to this so far, as it is commonly reported among various brands of the PX5 Android boxes.
I am going away, so wont be able to look at this for a few weeks, but would like to hear from anybody who is game to try removing the screen from the case initially.

It's not the LCD, at least on my unit. The noise is much higher if I connect a flash memory to one of the USB connectors. I can hear the noise as Android is reading the memory content. I think the noise from the digital domain is getting to the analog path somehow. Would be interesting to install some power filters for the analog part or play with the grounding. May do it later if I can find some free time... I do have an oscilloscope but I don't have the time for the research yet...

I found it easier to track down with a signal tracer, i.e. a probe connected to an audio amp and headphones.

I removed the main board from my unit. Bottom layer on the PCB is filled with a ground plane but has many connections cutting through it. I'm wondering if they have a dedicated ground plane as a middle layer. If they don't it's possible there are ground loops which can cause the noice. I will try to add some wires to improve the grounding. Will update when I have any info.
i can hear static too but from my little speaker that produces the parking sensors and indicators sounds.. when the unit seems to be processing i can also hear some. Let us know later @G0bl1n.
Hello, I have the noise when the car radio is connected to wifi or bluetooth
Guys...check your Wifi angena on the back....it makes this annoying noise. Change wifi antenat to external on the cable.....it fixes issue 100%

Can someone else confirm this solution please? It's very difficult to dissamble the head unit from my car.

Did you find any solution? I have the same problem
Any updates on this? I'm experiencing the same issue when the LCD screen is bring used... Eben noting a significant difference between noise when a live wallpaper vs a plain wallpaper is being used. Would in line magnets in the power and ground source help? Any progress? This is really frustrating

Not sure if it's the screen itself or the electronics on the board controlling the screen. If I ever get more time on my hands what I would love to do is try extending the ribbon cable on the screen so I could remove it away from the unit and see what that does for noise. If it works then you could always dash mount the screen and stick the unit under your seat... or what ever. Haven't had the time though.
Anyway, there have been a lot of threads and posts on noise with people trying all sorts of stuff to stop it and I haven't seen a foolproof method yet.
One thing which seems to work for those using external amps is to use the speaker level outs and convert down as opposed to using the rca outs. Another thing which seems to work is to adjust the gain on the external amp down until the noise is no longer heard. You do obviously lose a bit of volume headroom though.
