History.
After the last update the audio on my Samsung Note 9 failed. Samsung support as always were no help other than to tell me they wanted 385$ to replace my main board (This sum is more than their own listed price for a main board).
So I opted to fix it myself. Being a hardware guy. I also asked for help on the note 9 forums. But only got the usual clean the lint in your ear phone jack, relaod the s/w, re-flash etc etc. All of which I tried. Then I found the service manual and ordered the chips related to Audio.
A friend came over the other day and he is convinced it is a software problem and not a hardware problem as the phone is under 2 years old. And in mint condition. No bumps, scratches, water damage.
He wants me to root my phone and then trouble shoot the problem.
I do not wish to root because I use secure folders and Samsung pay.
Still I want to show my friend that I respect his inputs.
So I will look into the software angle.
Android Related Question.
In windows if audio is not working. I know how to trouble shoot. You go to device manager look for an unrecognised driver and take it from there.
How would I do something similar in Android.
I know how to use ADB Shell and turn on developer mode.
So which logs do I need to check.
There must be log somewhere showing which drivers loaded which failed.
And why it failed.
Can somebody point me in the right direction. What are the files involved in defining what drivers to load. And the result of loading the driver.

I have a SM G900H (that's what the sticker inside says) that was an e-bay purchase from a Hong Kong seller. I have had a couple of small problems using it, but recently it has started getting worse so I want to try to flash another ROM. The problem now is, after trying to find out more about the phone I'm not sure exactly what hardware I have. Is there a PC utility that can "investigate" my phone, and tell me what exactly I have ?
Flash with Official Firmware

Please mention the types of problems you are facing. G900H is the International Exynos model. I have the same phone.
The ROM development for G900H is slow for some odd reason. To fix issues you are facing, which may be software related, I'd suggest you download and flash the official firmware.
Thank you for replying. I have had problems sometime with charging, the screenbegins to fade and if I'm too slow to respond by disconnecting the phonewill not turn on for a couple of hours. Some apps do not appear to work but iI think that the problem there is related to GPS issues. My GPS is rubbish. When I get to another device later I can state what shows as the model on Bluetooth. I can only remember the beginning which is ALPS. I would like to consider flashing a new ROM but I'm trying to discover what exactly I have inside so that I install the correct ROM for the phone. I have requested information from the eBAY seller but had no response.
Thank you again. More details later.
Apologies for not responding sooner, recent personal issues had taken priority and I've since become accustomed to some of the peculiarities of this phone. The issue I've had with charging (see above) could probably be explained away with a suspect charge cable/connector, as since then I have replaced the cable and secured it for my own personal use. Where the maps are concerned (including sat-nav) the GPS leaves a lot to be desired, in some instances it would appear to be up to a half-mile wrong. This also affects another APP that I cannot use for work purposes (OMNICOM'S Track Locater) that defines my location to help me establish if I'm within a "safe" area. Another APP I still cannot use is a reader of the new QR codes, that relies on the camera function and not the GPS though. I also keep getting notified that "the Galaxy Note 3 widget has stopped working". I have no idea what that means to me, or what it does for this phone. I'm glad that I've now found someone else with this phone, I was beginning to think that it was unique. I include this screen shot taken from the "about" section of the phone, maybe this build has been improved.
hi people,
the digitizer literally jumped out of my phone , with the summer heat . I went to the store and they ask for money to give me a budget that would probably be almost the value of the phone according to the employee. so I gave up the idea of fixing it and put away. now occured to me the idea of doing a multimedia system for my car with a navigation system and so. so far so good right?
here come the problems ... my pc ( ubuntu os) does not recognize it , I can not download the drivers because I do not know who manufactures it , and the store does not have the capacity to give me technical support . awesome !
I try otg mouse, I try adb tools, I try tons of things, nothing...
however, I know the phone is base on Broadcom 21664 Dual Core platform, and is running an android 4.2 version called 'hawaii' I think...
else, I did root the phone but for some reason it returned to the factory settings and is like it was first turned on.
what can I do?

Hi.
My cust-Android board is connected to a touch screen via a USB port. This touch screen fails to respond inrregularly on bi-monthly basis, which induces a great deal of agnoy for the testing process, and the product will be rolled off the manufacture lines in less than 5 months.
Currently the most troubling aspect of this whole ordeal is that we still couldn't quite decide if it's the fault of the onboard driver, the particular AOSP build we customized, schematics design for the board, which isn't done by us and the custom-designing studio vehemently denies any possible errors citing past experiences, or the cap-touch screen manufacture.
We are trying to narrow down the problem. As a group of people with mostly top-level software experience, I wanna know how to devise a plan to test this.
As of now we have installed a little robotic arm and have it touches on random places on the screen. But I'm less versed on the hardware/driver. How should I proceede? With limited knowledge, I understand frequent handshakes take place between the host side of the USB (which of course is our board) and the client side of the USB (which is the touch screen), is there and way we can document everything USB related and output to a log file on a laptop? Something like the adb logcat magic.
Can someone please help?

Hey.. whats the deal, no one?
I just want to monitor the usb connection, handshakes and/or keep-alive signals will be fine?
Hello,
I'm new to the rooting world and I am unaware of how to root my Fossil Q Marshal Gen 2... I use an iPhone so im planning to use android studio on my Mac for the same. Pls help me. Thanks.
In terms of actually rooting it, I'm afraid I can't help. However, I have a Fossil Gen 3 Marshall and wanted to do something similar, but my intent was to flash AsteroidOS. The response on here seems to be that it couldn't be done (certainly the flashing the new OS) due to the lack of ports. However, some long and intensive googling suggested that yours (and I suspect mine) does indeed have a data port, its just covered and internal. I have seen the four (actually, I think five) pins that I believe to be the data port, which might facilitate the flashing a new OS.
This is something I intend to keep looking into until I can find a way to keep Google from my devices!

Yeah popping the watch open and making a pin connector to touch the board with, will allow you access to Fastboot Mode. This has been proven on another Fossil Watch missing the USB Port. And Since I'm guessing most of Fossil's models remain the same with different aesthetic tweaks, most everything should be the same.
We just have to make a Fastboot Connector and then pop the watch open to access USB. I bet you they left most of the bootloaders unlocked that didn't have physical access to fastboot mode. I know my Smartwatch actually has all of its log set to ENG. So there is actually a lot of data to sift through in recovery mode logs and everything. But we can't access the data in user mode. But it is there if we can make the pin connector.
Also interested in this if. Will be watching for answers because I would love to remove sone bloat and mae my waych a little snappier in performance.
Aloha Everyone!
My S9+ screen has broken yet I can tell it's still functioning as my alarms keep going off etc and when I plug into my PC it registers the phone and should be authorized on this pc.
However since I can't use the screen I can't change the debug settings or put it into "file transfer mode".
I see Dr Fone, Droidkit, Phone Rescue etc. but they all seem suspect and suspiciously all want 35$. I don't mind paying if they work however they all seem to require I put it into debugging which once again I can't do with my broken screen.
Is there any open source solution to this? I would like the pictures on the internal SD of course but I need a recording I made with voice record for a meeting I have tonight. This is my priority and I am currently at work and don't have the time to scour forums and all the regular things I would do.
Any help is appreciated! I don't think this post is breaking any rules and if it is I'm sorry. The S9+ mention is specific but only because I need to explain the generation of the phone as it's older.
I know this is an old phone and I pray someone sees this, infinite mahalos for any suggestions or replies in advance!
You Rock!
Is your screen responsive to touch (Even if you can’t see what you are touching)?
I saw you said broken, do you mean physically? Can you see anything on the screen?
Could you use scrcpy?
It has a few small cracks that water got into and fried the screen I believe.
My alarms going off at the proper times, if I touch the buttons it will vibrate in the ways it should etc.
It doesn't seem to be responding to touch however and it is black as in off, no color or light.
I am looking into scrcpy! Thanks, if anyone has any other suggestions that would be much appreciated!
Spcry won't work because I am not in debug mode, or rather never authorized it while I had it unlike all my previous phones. I got bored of homebrew apps and didn't bother doing it on this one.
Not sure there is anything you can do. No PC programs can control, no Bluetooth mice, no nothing.
Damn, you would think there would be a program at this point to bypass everything and grab your files.
Thanks for your help everyone!
If there was, I would be patched right away, and whoever reported it would get thousands of dollars for the report.
im pretty sure you can use a usb c hub with hdmi and usb to plug in a mouse and your phone to a tv
This is late, but questions do NOT belong in the Development section. Also, this post is for a S9+, not an S9.
Thread moved to S9+ Questions and Answers.
