Ever since the Oreo update my phone displays a modal dialog when I connect to the USB port in my Subaru for charging. The dialog suggests that the phone resources can't be accessed and that I should download a samsung app (the one you use to port data to a new phone). All I want is to charge the phone like I've been doing for the past 6 months. It's inconvenient because I have to wake up the phone and hit OK to dismiss the dialog box. Is there any way to tell the phone to just use the USB for charging only by default? I tried changing to charge phone only in the drop down notification panel but it doesn't stick for the next session. I looked through the very extensive list of settings and couldn't find anything relevant. I know that I could try to find a cable that offers charging only or perhaps connect the phone to a cigarette style charger. These are inconvenient as I already have the appropriate USB-C cable and charging port. Am I missing the setting or solution? Thank you.
Here is a picture of the annoying message that recently appeared on my phone after updating the OS. The message appears when connecting my phone to my car's USB port for charging. Does anyone know how to stop this message from coming up? Thanks.
Have you tried plugging it in, acknowledging the popup, then switching usb mode to charge-only? It should remember that mode for future plug-ins.

I get that same message when I plug into the airplane media system USB to charge. I just switch USB option to charge and it goes away.

I tried the same thing to see if it would work and it doesn't save your preference. Tested via both the notification and via developer options.

Yes, extra fiddling with my phone in this way is inconvenient and unsafe while driving.
It is a rather inconvenient, and annoying, situation.

One of the things that bugs me about Samsung is that the number of settings available are enormous but many don't work the way I want.
This seems like a simple problem that was recently introduced. I guess I need a charging only cable....

Got my new GS6 a week ago and now i went to transfer some images and when i connect it to the computer it makes the USB connected sound and suddenly starts disconnecting and reconnecting like crazy, has anyone else experienced this? gotta get my hand on a replacement cable just in case thats the problem..
Yeah it's the cable

Same problem here and mine s6 is only 26 days old.... support told me it's the cable but refused a replacement... what the hell right?
I have the same thing and have tried a few cables. Did you get to the bottom of the issue? My laptop is a dell xps15 and it happens with W8.1 and Mint17 (on the same laptop).

its the cable.. same issue here..when I use a ps4 controller-cable i have no problem
Yea... I think it has a lot to do with the placement of the port on the phone and and a filmsy input. I tried tried a sturdier cable and it works waaaaay better.
Samsung support did offer to send me a prepaid envelope for my cable. ... then wait 2 weeks for testing... then if it was found to be defective a replacement would be shipped free of charge, but if it was defective due to user abuse then they said they'd send me a repair bill........... SERIOUSLY wtf?
I'm not kidding, this was their solution when I spoke to support.
Well it really was the cable, went out and bought a new one, exactly the same and it works fine, so the one i got in the box was faulty, after some googling it seems this has happened to a fair bit a of people already,
i still use the crappy cable to charge with... although it did stop charging half way through once :silly:

I tried this and still it doesnt work. I changed the cables , I changed the PC which I am connecting to and still no fix. I keep getting disconnected continuously.
I'm having the same problem with Galaxy S7. It keeps disconnecting data after it has been plugged in a few seconds. It's not a cable issue, I've checked on 8 different cables.

Flash a different ROM. I had this on my s6 e+ on stock nougat. I went to Dr ketan ROM and it stopped
I heard it could be due to using a fast charging cable. The phone attempts to draw out more current than the USB port of the computer allows, forcing it to disconnect/reconnect repeatedly. Try using an older/less-current-rated cable. Alternatively, if you don't actually need to access the files and are just charging the phone, you can go to Window's Auto Play (search in start menu) and set your phone to "Take No Action"
I wanted to throw out a few other tricks to try, for whoever comes across this old thread when googling.
I don't 100% have an idea of why this happens, or why this worked, but it did.
First thing is, the cable really does matter. If you're using a cheapo cable that doesn't do fast charging, or a data-only cable, get a nice cable. If you're using a nice cable, try a non-fast-charge cable or the one that came with the phone.
My fast-charging cable has worked for a while but I recently tried to transfer a large 2 gig movie to the phone's secondary SD card, and it kept disconnecting / timing out.
What worked for me is go to developer options (google it, there's some code you have to enter to unlock these settings) and then usb debugging. It was disabled and I enabled it. The transfer then worked smoothly.
Weirdly, another transfer right after did NOT go smoothly, and the fix for me was to disable usb debugging, then enable it again. Then the file transferred normally, even though it took a few minutes.
Lastly, one file refused to transfer that was sitting in a particular folder. I'd get an error instantly. The folder was the cache folder for a popular video downloading app. Even a tiny text file from that folder, refused to copy. But files from other folders worked. I finally figured out that for whatever reason, the phone (or maybe windows) didn't like copying straight from this folder. Not sure why. Some permissions thing? Anyway - I copied the file I wanted from the cache folder, to a folder I use all the time. Then from this new folder to the phone. Worked smoothly, no error.
Hope these tricks help someone.
So I think something on my USB port has malfunctioned... it won't show up in the device manager when I plug it in.
I have tried the sticky thread on Diagnosing USB Driver and ADB issues in Windows. I have searched the forums and internet and tried lots of driver installs and restart this and that.
Recently this started when I wanted to flash Android 6.0 to my phone. During the install with NRT after each erase and flash it would say Waiting for device, and the only way I would get it to proceed was to plug the USB and plug it back in... Now running Android 6.0 it won`t even recognize my device and won`t pop up the menu to choose your usb connection setting.
I have two Nexus 7, one Nexus 7 (2013), and another Nexus 5... and they all work fine and get recognized by the computer.
Please help, and is this fixable?
Am I going to have to do some phone surgery and change out the charging assembly?...
Does it charge when plugged in?
It charges when plugged in... I guess 2 out of the 5 pins are working.

So you don't have a notification in the notification shade that says the phone is charging? There should be one that, when you tap it, opens up a dialog box to change it to a different connection.

Yeah it charges and it shows that it's charging with the lightning bolt on the battery icon. But not like my other Nexus 5, it does not pops up that menu with the different options (charging only, MTP, etc).

The menu doesn't pop up automatically. You have to tap on the notification. Maybe you need to turn on USB debugging in the developer options?

Each time I get into my car and connect my OnePlus 6 via USB, I have to change the USB connection type on the phone to MTP in order for Android Auto to connect. Once I change the setting and it connects, Android Auto runs well and stays connected until I turn off my car. Without changing the USB setting, the phone will stay in charging mode and Android Auto does not connect.
My car is a 2016 Honda Accord EX and I am using an OEM cable. The phone is rooted, developer options are enabled, and USB debugging is off. When I go into the developer options and try to change the default USB connection mode to something other than charging, the setting change doesn't seem to take.
Is there a way to automatically use MTP mode when I connect the phone to my car? Or something else I can do to get it connected without having to change a setting on my phone each time I get in my car?
I would clear data, force stop, and reinstall Android Auto. I use it every day and have no problems at all. Connects automatically.
My HTC M9 had no end of problems with AA. Would not connect half time time unless I replugged it in, and the voice-to-text function was buggy as hell. My OP6 is smooth as silk.
Thanks. I tried that and even deleted the phone from my car. It didn't work. I had to change the mode to mpt to get it to do the initial connection. Same for reconnecting. Doh!
Do you use Tasker? I wrote a task that will automatically change the setting to MTP. It requires the Tasker plugin - AutoInput as well.
I do have tasker. How do I set it up to do that? Thanks.

So I actually created two different profiles/tasks.
1) Detects when USB power is plugged and then opens developer settings and scrolls automatically to usb configuration and makes the change. This profile/task requires the plugin AutoInput.
2) Uses AutoNotification to detect when there is a notification in your tray stating that the device is being charged. Then it will use AutoInput again to click on the notification and change it to 'USB for file transfer'.
I only attached #1. Import it into to Tasker and see if that works. If not, I can add the second option.

God, it's annoying. It happens in all the modern androids. My S8+ 5T and now my OP6
My OP6 has no issues connecting to my Pioneer AVH-2330NEX. Just plug it in and AA starts right up. Bluetooth is pretty reliable as well, which is how I connect most of the time.
It usually takes a minute or 2 for my AA to come up on my screen (2017 Charger). Once it's connected, it runs super smooth. But I wish it was a little more responsive once I plug in the cable. Now I have to wait for it to come up before I can launch any app (Maps, Spotify, etc)
I"m going to see if the MTP method makes it connect "faster". If so, I'll look into building a Tasker Profile as well like @azsl1326

This is really close. I had to add one more scroll down step in the developer menu and change the mode to MIDI. It doesn't work 100% though. If the developer options menu is already open, it reopens wherever it was and sometimes the scroll down goes too far... Perhaps there is a more stable way to do this?
Attached is my modified tasker profile.

I have another profile that uses AutoNotifications to detect when there is a notification in the tray regarding USB charging. It will then use AutoInput to select this option from the notification tray and change it to 'Transfer files'. I can post that here if you are interested. It does require two paid plugins.
You could add a task to clear recents before running the AndroidAuto task - that way it should ensure that Developers Option screen is no longer active.

I replied to you in the other thread, OnePlus 6 and Android Auto
But to fix your issue, this MIGHT be the solution for you specifically. Setup an appointment with your local Honda dealer, and ask to get Technical Service Bulletin 16-059 installed.
This fixed my issue for my '16 Accord when AA wasn't working at all with my PH-1
Or you can just simply choose this option to mtp as default on USB connection. It's in developer settings.

Didn't know that..
I had the same issue with a VW Passat 2016, and the solution was to enable USB debugging, and after that everything is working ok.
Unfortunately I'm facing another issue. If I'm initiating a call with the phone connected to AA, usually by voice command, the sound is routed randomly on the headset, speaker and sometime to Bluetooth.
Every time I have to set manually from phone app in AA on the car screen to route the sound to Bluetooth, and this is annoying. . Do you experience this issue as well?
Thanks!
Hi all, I'm afraid I already know the answer to my question but I'll still ask if there's even a slight chance to get this fixed on my own.
I had this issue on Android 8.1 where my Pixel kept saying "Supplying power to connected device via USB" even without anything connected to it, (it started doing that one day without any reason) tapping the notification allowed me to switch to "Charge this device" and then turn on MTP mode, battery life was terrible but I wasn't that much bothered by it because I am an Android developer so I kept it connected in USB Debugging mode most of the time anyway.
When I got the notification for Android 9 update I decided to update hoping it'd fix the USB issue but after the update it now always says "Charging connected device" and tapping the notification does bring up the "USB Preference" screen and it allows me to switch to "USB Controlled by this device" and it starts charging but there's no way to switch "Charge only" mode to anything else, ADB does not see it, fastboot does not see it and there's no persistent notification on the phone about it being connected via USB at this point (in any mode). My understanding is that this is a hardware issue but Oreo still allowed me to workaround this and get the USB debugging connected.
Is there anyway I can get back to Oreo without using fastboot flash or any other solution to this?
Thanks for reading.
PS. I'm on Ubuntu but I can access a Windows machine if required and bootloader is already unlocked.
I'm curious if you're able to connect to a USB OTG storage device.

Same here! I plug the cable into the Windows 10 computer, I even can change the mode from charging to MTP file transfer, but the device won't show up in the Windows Explorer. It appears under connected devices though.
My Pixel 2 XL would not connect to PC for file browsing if USB debugging of Android Apps was enabled in developer settings. Didn't matter which option I chose to connect. IDK if that is expected or not, but it took me a while to figure out. Happened Spring 2018, idk if Google fixed it.

Couldn't find any OTG cable to try that but strangely enough a few days back I connected it to PC for charging and Nautilus popped up, same cable, same USB port and it started working all of sudden. Did verify with a couple of other cables and different ports and everything is working fine since.
"Charging connected device" notification never appeared again, only thing different (when it started working again) was that I was out of the air conditioned room most of those days, might it be moisture or something like that?
I'm back to my normal routine for a few days now and it's still 100% normal, will have to see if it stays that way.
Sorry for late response.
Here's an update in case someone else runs into this situation, I can say this with 99% certainty that is caused by the blackish residue build-up around the USB port over time. It's not too much that it's visible just by looking into the port but it's enough to make the device behave like this.
Here's what I did to get rid of it, took a match stick (don't use anything metal) and broke it in half making a sharp edge on both broken pieces, took the non coated piece and inserted sharp edge in the bottom side of the port and gently wiggled it around while applying some pressure towards the connector (just a little bit, make sure you don't break anything), did this for about 45 seconds then took out the match stick and the part that was touching the connector had turned blackish (I guess this is when you know you have 'cleaned' it enough?), repeated the same process on the top side of the port with a new match stick piece (guess you can use the same one after cleaning it with a tissue), the only difference was that this time applied the pressure in opposite side (other side of connector), device was on during all this time.
It builds up again after a while (~3 months) so I had to repeat the entire process again when it started doing that again at the start of December but it wasn't that annoying this time because I knew exactly what was wrong and how to get rid of it, device is still working fine 100%.
I'm simply sharing my experience and not encouraging anyone to do this but if you do decide to try this be sure not to use anything metal and don't break the connector inside the port (turning the device off would be a good idea too) and you'll be fine and if something does go wrong I won't be responsible.
For some reason I can't connect my Pixel 4a to my PC with a USB C - USB A cable (or USB A - USB C, not sure what the official name is) , even though it worked fine on my previous phone.
Included with the phone is a USB C - USB A adapter, but I see no use for it unless you have a special USB A cable which I don't.
My motherboard does have a USB C slot on it and it does read my phone when I plug it in that way but for some weird reason it's really loose and doesn't stay connected unless I keep physical pressure on it.
I'm not going to update to Android 11 until the November update because I've heard the current build has a few bugs, but does anyone know if Android 11 fixed the USB C - USB A issue?
Have you made sure to switch to file transfer mode? It defaults to 'no transfer' mode when I plug into my laptop.
Most likely you need to toggle the phone connection settings to data transfer, originally it will be set to charge only I think.

I had this issue too. Windows file explorer would just crash after one or two files and stop transfer, no matter the size and type. (Yes I had file transfer selected on my phone ?)
Then windows update gave me a driver called "Google Inc. - Other Hardware - Kedacom KDB Composite Interface". I also updated to the newest firmware on the phone. No idea which of these did the trick or if it was the combo. However. Smooth sailing now ??
Hope this helps
(If windows update refuses to give you the driver, you can get it from Microsoft's update catalogue online. A Google search will do)
Ok it's completely messed up. When I search for USB settings it doesn't let me change anything at all, even though when I first got the phone I could and I changed it to transfer files. EDIT: No actually the setting that I changed was a developer option called "Default USB configuration" which I changed to transfer files but that still did nothing.
I just plugged in my phone and looked for the USB setting in the notification area but it wasn't there, but I noticed an option called "manage"
I went in there and noticed this. (see attachments) it's locked to be off and I can't change it. Very odd.

You're in notification settings. Try short tapping rather than long tapping to get the menu to pop up allowing you to select data transfer.
Changing default USB settings in developer options doesn't work for me either.

My point is that the notification that normally comes up when you plug in your phone to a computer to change to data transfer, charge only ect ect isn't even coming up because the firmware is stopping that notification from coming up altogether and I can't change it so it does.

Almost certainly a cable or host port issue. Swap cables and see what happens. Same for hosts/host ports. You're not going to have toggling options if the phone does not 'see' all expected lines/pins.
I had the same issue and changed to a different cord to fix the problem.
You have an non certified cable it seems, I've confirmed this pixel 4a works with only certain cables for usb transfer, also the usb a to c cable you have will not charge the device as well.
Get a cable from know manufacturers like Samsung, it worked for me.
Yeah turns out it was a cable. Strange how my cable worked with my old phone but not with the Pixel 4a
Had this issue with my new 4a just now. Cable was fine, even used the new cable that comes with it using a Usb C to Usb A adapter. Nothing worked. Upon opening Device Manager I found a new device called 'Kedacom USB Device'. After trying random things, I decided to uninstall the current drivers by right clicking on it and clicking 'Uninstall device'. Suddenly the phone connected, and even showed the adb prompt.
So for anyone still facing this issue, hopefully this solution might help
