Recently we have been getting in stock i997's that are having USB issues connecting to the computer. As always we enable USB debugger and connect to the computer however now the units are going into charge mode a few seconds after connecting to the computer and shutting the device down. Once we disconnect the device from the computer it automatically restarts.
Here is what we have done so far with no luck:
-Enable USB debugging
-Disable USB debugging & enable mass storage
-*#7284# was set to USB=PDA, changed to Modem & back to PDA
-*#9090# Didn't see any relevant options
-Slightly bending the USB port
I don't think it is a hardware issue but a software issue that needs to be configured. Any help would be very much appreciated!!
USB
Get it as stock as you can with software. If the USB still does not connect correctly then it is a hardware issue. There was never a problem in any stock rom with USB connectivity.
Just my thoughts. It may not be the phone but the connection-- Computer, cable, oops,-- or drivers.
I'm facing the same problem !
I too have the same problem very weird tried several time stock have no issue in connection. this issue occur after few days not immediately and no regular pattern so can't say what's going on. right now my phone while put on charge shows charging but when un plug it still have 1% as charge no battery put to charge message shows up, tried with charger, usb to computer.
I also noticed before that charging stops and only come in effect when you pull the battery and plug the cable put the battery it will start the phone automatically and charge start up.
Can't ever put in charge in switch off mode as every time it automatically switch on my phone.
I tried several time these step 1. Go back to stock by heimdall , 2. heimdall kernal flash for red cwm, 3 wipe, format, fix permission 4. flash
couple of days work smoothly then problem reoccurs
Did you try mtp mode like with media player mode

Thanks RDomke for the reply.
We already flashed UCKD5 with no luck. Would there be anything else we could do? I agree that it may be hardware if stock doesn't work but we have been getting in too many units out of box with this issue. Not saying that it isn't possible to be hardware, just seems like it's something that could be software related.
SOLVED

RDomke,
Many thanks as we have solved the issue with your advise. The 1st unit we were testing did in fact have a bad usb port. Once properly diagnosed we tested another by flashing it back to stock and then performing a factory reset. Once done issue was solved and worked on many other with same issue.
I have a MTCD head unit MX (witson) with Android 5.1, my problem is that the USB port cannot recognize my phones, A note 4 with Android 6.0 (eRobot ROM) and a Samsung GT386T no rooted with stock ROM 4.4.2. The USB port works find with a usb stick, I can play music, pictures, etc. but not my phones. Both have the USB debugging enable.
When I plug a phone it is charging but nothing happens, my note 4 after a few minutes pop a windows saying that there is a problem with the connection MTP and that I need to download samsung Sync etc.
What I want to do is to use the mirror link function.
Any of you know something about this issue?
Thanks in advance for your help.

I believe i read that there is a specific app that you have to run on these to do the mirror link...easy connect, maybe? Did your HU come with an instruction booklet? I was looking through mine earlier and it went over in detail how to setup mirroring through that app.
Yes, when I tried to use EasyConnected is when I saw the problem. The app waits for my phone to be connected, It says that it must be turned on USB debugging, but it is on. Then I checked in the File manager and the USB was not enable there, like if nothing is plug it. If I plug a USB memory it works fine.
I will try today to do a factory reset.
Thank you!

You ever get this solved? My easyconnected never stays connected. WiFi and USB both are garbage.
WiFi randomly disconnects.
USB also disconnects asks me to allow USB debugging every couple of minutes. The phone never remembers the headunit, so it constantly asks me again to allow connection. Must be a crap RSA fingerprint coming from the headunit.

Nope, Still does not work for me. Same symptoms as you. I already tried with 3 differents phones, factory reset and different versions of easyconnected.
I seem to have USB connection working now with only one "allow USB Debugging?" popup, only when I first connect.
What I did was turn wifi off on the headunit. I am not sure why it worked, but I just wanted to turn everything not needed off, and see if the headunit would stop disconnecting all the time. So far so good. I can probably live with one annoying popup, instead of one every few minutes.
Of course you have to keep the screen on the phone on, and the battery in the phone will deplete faster than the headunit charges it, but still an improvement. I had a 30 minute drive today, and the USB never disconnected!

paniqueado, try the da_anton ROM. I just installed it and easyconnect finally works as it should. I just plug in my phone to the USB and it fires right up! One prompt if any on the head unit, and NO disconnects whatsoever.
Hello all,
I'm fairly new to this phone but I have been loving it so far. I've had a few issues with it, which most have been resolved (such as the phone defaulting to loudspeaker on phone calls).
Now my biggest issue is the USB connection. I first noticed it when I used to llug the adapter in for my headphones. The port worked great for a time and then I believe it was a security update that was released which seemed to jack it all up. Now I cannot use the port in the bottom of the phone for anything other than charging. Cannot use the headphones, cannot plug in my drone mavic pro (requires the phone app for on-screen first person flight), and I cannot plug the phone into the computer for data transfer.
I have pulled out the book of from my IT troubleshooting days and tried these solutions with no luck.
•various USB cables
•went into settings while phone was physically connected to the computer under connected devices, the USB section was greyed out stating not connected.
•checked in developer options us debugging on and off. I tried both ways for good measure.
•checked USB configuration type. I tried MTP, PTP, and RNDIS.
Any ideas?

I recently had similar USB symptoms on my Pixel 2 XL after the March security update. Also tried it in safe mode and tried factory data reset, but neither helped. I asked Google to replace the phone. Replacement works great, even after March security update.
Umm..I just recently had this issue. TBH I used a 3rd party cable but until last week it could 1. fast charge and 2. transfer data (included adb/fastboot), now however it does only charge, no whatsoever signs of connected device. Bought a new one, it does charge, sync(fastboot, adb,..), no fastcharge but ok.
Have you tried reflashing the March ROM (with the -w removed)? I'm running the March update (did the February too back in February) and I can still enable MTP (I just don't like that it doesn't stick in Oreo - coming from KitKat, that was - and still is - annoying.)
So I tried flashing the March update again and still had no luck. March update was a security update so whatever they did it must be in the coding. I got a warranty replacement for the phone and it works fine. I'm able to do data transfer and fast charging. I was very reluctant to install the March update again but after ignoring the notification for about a week, I installed it and it is working fine.
I talked to Googe about the issue and they said that the bug was fixed but for those phones that had the firmware installed, it has the issue permanently installed. The only option would be to replace the device.
When I plugged in the usb cable yesterday morning to my car, android auto did not start. When I came back from work I tried to plug my phone into my computer, but the phone did not show up. Normally you get a notification where you can choose between charging only, file transfer,.... but I don't get this notification.
I already tried to use another pc, another usb cable, tried to do a factory reset, but all with no success. I don't think it is a driver issue, because last week everything was working fine and also when I plug in my OnePlus 5 I immediately get that notification to choose between charging only, file transfer,...
Anyone of you experiencing the same issue or knows what is wrong?

Omg yes
I cant figure this out either
Been stressing me out tons
You can set default USB behavior in Developer Options (i.e., which become accessible if you tap About Phone's --> Build Number a bunch of times). If all troubleshooting alternatives become exhausted, I would suggest backing up any important files to an external drive, and flashing a different ROM or possibly using MSM tool to re-flash stock. MSM tool might be more thorough than some other options, so that's what I would do if nothing else solved the issue.

One possible option is to try booting PC to some Linux distro live USB and seeing if the PC recognizes the OnePlus 7 Pro. Another option might be booting to TWRP recovery and seeing if the PC can recognize the phone when connected.

Thank you very much I will look into this when I'm back home from work ?
After trying this without succes, I decides to send my phone for a repair via OnePlus. I filled in the repair form and the next day a UPS guy picked up my phone. A day after, the phone arrived at the service center. The same day the phone was repaired (replaced USB fpc) and send back to my home. So basically in 3 days my phone was repaired free of charge. I have to say I'm very happy with the service OnePlus gives! ??

I had this problem and I just turned off USB debugging from developer options and it immediately connected after restarting my device and my car. Hope this helps!

Thanks but it's already fixed. I sent the to OnePlus repair center and they replaced the USB fpc. The service OnePlus gives was really good, My phone was repaired in only 3 days ?
The dash cables also go bad and are very sensitive. Sometimes they still charge but no data connectivity.
Hi, I have a S10e T-Mobile which runs Snapdragon. When i used my phone on May security patch, the phone was okay. I can connect it to my pc without any problem. But yesterday, when i update it from May patch to September security patch then when plug it to my pc, the phone shows only charging. I even try to go to download mode and odin can't recognize the phone as well.
Yeah, yesterday on May patch i plugged my phone once and still okay til i updated my phone to lastest update. Anyone has the same problem?
Update: I changed my phone case and the phone now can connect PC and charging faster than before. Maybe the cheap phone case is the problem.
Update 2: After October patch, the problem now comes back. T-mobile forced me to install so i think after a few week the problem will be gone
Update 2022:The problem now is gone, i tried serveral update and I can't trigger the bug anymore. Thanks everyone.
If it doesn't show on Odin, you're screwed. The only way is to report and wait for an update. Have you considered doing the common steps?
Another USB cable? Another PC? OTG? Fast charging? Port clearance of any obstacles? Reboot? Wipe cache? Factory reset? Safe mode?

Yeah, i try everything like:
- Clean usb C port but it has only some dust and still can't do anything after that
- I have about 5-6 usb C cable and i only use one. The others are all new, i just buy them about 1 month ago. My redmi note 7, redmi 8A... still can connect but not my S10e
- I try other PC but it couldn't recognize my phone
- Disable fast charging but still can't connect
- Reboot, clean system cache, factory reset but nothing changes
Maybe new update just broke the ability to connect usb?
The bug may not affect me much because i use FTP and cloud services but may be for another it'll be a huge problem.

Yeah you're totally screwed. That update was definitely bugged. The only thing you can do is to file a report through Members app and wait for a hotfix.
I got a semi-new device that was working great, on One UI 3.1, but once an update came, I updated the phone, and ever since, the green tint problem showed up.
If I ever bought another Samsung phone, I'll never update it. The only exception is through custom ROMs.
Try this:
1. You basically need to perform hard reset on the phone while S10e is connected to the PC through a USB-C cable
2. To perform the hard reset press POWER + VOLUME DOWN at the same time until system shuts off
3. Now it would either reboot on its own or you would need to reboot yourself
I tried this as my phone was neither charging nor connecting to PC (error about something wrong with my phone's USB)

I have the same issue on a G970F. Unfortunately the POWER + VOLUME DOWN method didn't work. Am now wondering if there's a hardware issue. My other G970F is fine. Both are running LineageOS 18.1.
