USB Not Reconized, phone just charges. - Samsung Galaxy S8+ Questions & Answers

Hi all,
Suddenly my pc stopped recognizing my s8+, tried several pcs, macs, even my car doesn't recognize it. When I plug the USB Cable(OEM) nothing happened, the phone just charges, and I try to change the USB configuration but nothing happens, not even adb recognize it anymore. One morning it start working again, but next time I tried again, it stop working again.
What can I do?

is debugging enabled? (just starting with simple stuff first)

U have a bad port mine was like that it would work sometimes for 5 min and then unrecognized it shorted out or something

First try to change the cable. this will be the cheapest solution.

Yes it is, sorry I didn't specified it.

Already tried. Thank you.

What did you do? take it to warranty?

usb not working on my polaris

Usb is not working on my polaris. When i connect it to my computer nothing happen. The computer wont eve recognize that i connected something. I have tried to hard reset it, but it didn't work. I have flashed it with c_shekar v3 rom. I also have radio rom v. 1.58.25.14. The usb port has worked great for some time now, but suddenly it just didn't work.
usb problem
I had the same problem and the solution was really bizare. I let the phone into the usb, charging and after a while i heard that usb pluging in sound and imediatly after that the usb pull out sound, then after some time it happend again, and again. The fourth time i think the connection was stable and activesync worked. I did nothing, weired , i know but this is when windows meets windows through another company. Oh, and see if the usb on the phone is clean.
I did try to clean the usb connection on the phone, but it didn't work. I have also tried 4 diffrent usb cables. I am trying to flash another rom from the sd card, but that isn't working either :S The phone have been connected to the computer for several days now, but nothing happens. Maybe the moisture in my skipants killed it? (I spend at least 4 days a week on my snowboard) Maybe I'll just use it for skiing and dh, and buy a diamond for normal use.

help! my sensation cant be detected on my computer

Yes I know some will say install drivers or slide down the notifications.
But the problem is when I plug in, there isn't any notification for you to switch to disk drive mode.
Everything was working fine last week. There was no problems detecting my phone on my home and any PC at work. I have drivers install in my computer and can do adb commands
But now, when I plug in, it only shows the charging light.
I have done the following
On and off the USB debug option
Reboot phone
Try a 4 micro USB cable
Tried different USB slots on the computers
Use usbdeview and delete all HTC drivers and resinstall also not working
Remove my micro SD card and reinsert.
All doesn't work.
Strangely, one thing does. When I plug in the PC and I need to reboot, with my phone still plug in my PC. The notification will appear and I can do all things normally. But once I unplug and plug in again, same problem. Only can be solved with next reboot with phone plug in before hand. If windows is already loaded, it cannot be detected.
I though it was the rom. But I went to boot loader and same thing. It shows fastboot AC. If I do the reboot windows method, it will show fastboot USB .. will show fastboot AC if I replug in
I am starting to think my USB port on my phone is faulty.. any ideas?
Try plugging it and wait for a long time. Since I formated my computer it takes like 10-15min for my phone to show up after I plugged it. No idea what's causing it though.
Done that , charged it for 1hr plus, same
Best thing is try different cable, there is some issue with htc cable your pc sometime dont recognize phone, Other thing you can do it is keep ur phone connected to pc then boot your phone to Hboot or bootloader or fast boot, your pc will recognize your phone with generic driver.

hmm tried 4 cables.. same results..
Using the same cable, tried my mum's desireHD.. no problems detecting the USB each time..
Bootloader mode, it shows Fastboot AC
instead of Fastboot USB.. unless reboot my windows..
Oh i tired another micro SD card, same results.. :/
why mess with cables... AirDroid.
connect your phone to the pc via wifi.
direct link to the market: goo.gl/9YG73
but if you must connect via cable for something... have you checked the most obvious place? (sounds like you probably have but just in case...)
settings > connect to pc > default connection type

Flashed ROM......
Mine is doing the same thing. It didn't start until I flashed the new ROM. When in Windows, I just un-plug it, and re-plug it. Then it shows up immediately. But it always seems to show in flashboot.

and if that isn't working try it with HTC sync. which gives you the drivers of the device.
I got the same problem... any idea...
please help me..
Is there where USB cannot be recognized issue? If this is, I have a simple solution which took me forever to figure out.
I know this method sounds ridiculous, but give it a try. Unplug your charger connected to your computer/laptop and plug it in to a different outlet. Replug the USB with your phone connected, give it a sec, and it should work.
what operating system is your PC running? I was gonna say perhaps it might be a faulty USB port...
i have the same problem
What I do is go to devices and printers and then android phone then properties then hardware and disable the reenable the drivers. As soon as you reenable the drivers it should show up in disk mode. Hope this helps. This is the only phone I've had this problem with.

Unable to connect to PC in any mode

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.
I'm having this issue connecting it to my windows 10 laptop.. the cable recognizes it.. starts charging.. shows option on phone to change type of connection.. but not matter which one i change it too, the computer will not pull lit up as a drive to see the files..

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.

I don't think i've tried to turn that mode off.. i'm so used to needing it on for the computer to recognize and connect to all my previous Android Devices.. thanks for the recommendation...

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.

Question Phone no longer being recognized by computer. Not even getting a prompt on phone when plugged in.

As the title states, my phone is no longer being recognized by my computer when I plug it in. I've tried multiple cables, multiple ports on the computer, both ports on the phone, factory resetting the phone, uninstalling and re-installing drivers on my computer, booting to Ubuntu so I wouldn't need to worry about drivers. Nothing has worked. I'm not even getting the USB prompt on my phone when I plug it in. It DOES charge but I'm not able to transfer files, adb or anything. ASUS wants me to send the phone in but I don't want to go who knows how long without my phone, plus I don't think it's right that I have to pay to ship it when it's their phone that is ****ting the bed. Could anyone PLEASE help me? Thanks.

If your phone won't connect to the computer using the USB cable, then the FIRST thing most people do you've done, which is switch cables and rebooting the phone (factory reset is extreme but you did that also).
The second thing most people do is install the manufacturer's drivers, which you also did.
The third thing you can do though, is connect the phone to the computer WITHOUT the USB cable (i.e., over Wi-Fi) because that will work even if your phone port is broken and even if the USB cables are bad and even if the drivers aren't on the computer.
Below are screenshots of just some of the ways to connect the phone to the computer over Wi-Fi without any cables, and if you want, you can follow one of my tutorials on the subject.
Hope this helps.

Would I still be able to adb using the wifi method? My main issue is trying to remove the old Google Pay app. Which I'm unable to unless it's through adb.
Just an update. I was, in fact, able to run adb commands while connected using wi-fi. Thank you @GalaxyA325G for your input.

Not sure what to tell you about your signal dropping, but
is the video I used to finally use adb via WiFi.
Have you tried clearing the adb authorizations (in developer options) with the phone disconnected and then connecting? Sometimes a change can trigger the phone to stop recognizing the computer as allowed without treating it as a new connection.

Windoiws not recognizing device

Hey guys,
I have a problem with my Note 10+. I want to access the internal files through my PC, but Windows is not recognizing the device, but it is charging the battery.
The strangest thing is that I spent 2 hours changing cables, usb ports and so on, nothing solved it, so I went to sleep, when I woke up I went to try again and at first Windows recognized the device, so I marked the problem as solved, however I tried again now and it didn't work. I'm using the same port, cable, etc., I'm absolutely sure that the problem is not in the computer or cable, because I tested it with other phones and it worked normally.
Does anyone have any idea what could be going on?
I tried to access it through adb, but it says that there is no device connecting (previously when I managed to make it work adb said that there was a device connected)
