Samsung Galaxy S8 OTG (USB On The Go) USB Host - Samsung Galaxy S8 Guides, News, & Discussion

How do I fix my otg issue? It connects but says charging connected device. Even with a ps4 controller at 100%. When I go to tick the option to switch it acts like it does then it goes back to saying charging device. I'm on stock rooted and tried this on all the current roms.

Hello,
I have had a good time using a usb c stick with exFAT to transfer files to and forth from my s8+. In the holidays I had water over the device and after the usb liquid issue. After some days it went away but now no stick , be it my usb c one or others with the OTG connector , is connecting.
Problem is that through cable phone connects to the PC ( although slower than usual ). Also charging first detects a fast charge through original charger and in 2 seconds drops to normal charging. For a while I have reset the device with the stick connected and it got read but after unplugging direct or unmount would
not reappear at a second plug.
Any ideas , this is driving me crazy ( even did a full reset to no avail ).

Nexus 5 Touch issue when connected to PC

Hi
I have been having this issue for sometime now. I connect my Nexus to my laptop using the USB cable, and most of the time the screen starts acting up. Touch calibration is all wrong. When i click something, the actual button that is clicked is totally a different one. And sometimes it activates stuff on its own.
I have tried several stuff I found on google. Some said it had something to do with my home electricity not being grounded. I checked. It is grounded. Tried everything from flashing new roms to freshly starting from stock! Nothing seems to work!
Its like this thing have a mind of its own
Hi, if you use stock wall adapter, it's working correctly? Usually that is some kind bad electricity problem or that device where you plugged it causes problems.
Check usb cable. If it's not happening on LG cable and LG wall charger than it's your usb to pc cable problem
PS check other usb port and cable

Defective USB Port? Data connection and Quick Charge not working anymore

Hello,
I recently flashed TWRP and CyanogenMod 13 on my Mi4. It was working quite well, I had some problems with the rotation sensor and some bugs in the software, but Quick Charge and also the Connection to the PC worked without problems.
Today when I was on my way home I was charging my Mi4 with a Qalcomm 2.0 Quick Charge Powerbank from Aukey (i have used it in the past on other phones, always worked great), but it seems that the USB cable was broken, it was charging very slowly and it also seemed to have a defective contact (the cable charged if i moved it around a bit, but in certain positions it wouldn't charge).
However, when i got home and plugged it in, I noticed that the phone also charged very slowly with the charger, so I thought that I would just flash MIUI back on the device to fix it, maybe it was a problem with Cyanogenmod. But that didn't work at all, the phone couldn't connect to the pc.
So, here's my problem: The PC can't detect the phone and it also seems, that the phone doesn't recognize, that its connected to a pc. Charging via the USB ist still working, but very slow. Also Quick Charging isn't working, it doesn't matter which charger or cable I use, it's always slow. When I connect the phone to the charger or the PC it takes like 5 seconds to recognize, that a cable is connected, then it starts (slow) charging.
The phone doesn't show up in the windows device manager at all (there are no unkown devices shown, the pc just doesn't react when you connect the phone). Also there is no message on the phone when you connect it (usually you can choose if you want the use your phone as a usb drive or just charge it). I also tried to activate MTP in the developer settings on the phone and turning USB Debugging On/Off, but it didn't help.
I managed to download a MIUI Rom from xiaomi.eu with the phone and installed it with TWRP, but it didn't help. So I think I actually broke the USB Port of my phone with a defective Micro USB Cable. The phone can still charge (very very slowly, no quick charge possible), but I can't connect it to the PC anymore. The pc also won't detect the phone when it's in fastboot mode.
I tried to look it up on the internet, but all I found were people with driver problems, and I don't think that I have a driver problem, because it seems like there is no connection between PC and Phone besides the charging.
Anyone knows something about this? Is it even possible to just break the data connection and the quick charging with a defective cable?
Hey, did you get your Mi working? I have a similar experience with mine.
Same Problem
hey i got the same problem did you find any solution ?

No, I didn't find a solution for the problem. Phone is still not working, I even ordered a new charging port, but I made a mistake and ordered one for the LTE version. I have the 3g version, so the new charging port didn't even work with my phone. I don't want to spend any more money on it, so I just gave up on fixing it.
Same problem, and I am also stucked in recovery for now, never will buy phone without SdCard now...
Somobody found solution?

USB Device not recognized / No fast charge

So I've had my S7 for around two months now, and all of a sudden fast charging just stopped working. Thought, oh, must be using the wrong cable (have loads of them micro USB cables floating around)
Now I'm certain I'm using the official Samsung fast charge plug and cable that came with the phone, and still no fast charge. When I try to plug into my Windows 10 Desktop or Laptop I have a message that says the device can't be recognized
Phone has already been rooted and flashed with a custom rom. Didn't think that was the issue as it wouldn't even show the mounted storage in TWRP, or identify the phone in ODIN.
Now I've flashed back to the stock rom that I made a backup of when I had the phone, and I still have the same problem!! Can't access internal / external storage using the supplied USB cable and can't fast charge.
I'm thinking the USB port on the device is just knackard.. but really, I've looked after it so well I fail to see how this could happen, unless it's a common fault.
Might just get a wireless fast charger, but do you guys have anything else I can try before giving up on the USB connectivity?
Cheers
try to connect to a different pc, if same it means your usb connector is faulty
Sounds more like the cable is bad tbh, you won't get fast charge from a PC USB port, only from the Samsung charger
But if the device isn't recognised by the PC, and won't fast charge from the charger, the common thing between them is the cable
Possible it's the phone USB port, but more likely the cable is bad
Afaik certain cables can not fast charge either, so chances are the ones you have lying around that are not the official cable can not support it
Genuine Samsung USB cable is white with the USB port symbol on both ends and the phone end has two small ridges to grip when inserting and removing it, should help identify it
Yep I'm using the official cable and fast charger
I'm trying to fast charge via the fast charger and not USB. Only trying USB to access the internal / external storage.
Tried on my desktop and laptop and both have the same issue where my old HTC m8 connects without any issue.

To fast charge I've tried the original Samsung cable with the fast charge plug.
To connect to the PC I've used x3 different cables that all work with my HTC one m8. With all of them I get device not recognised. Already tried installing Samsung switch and reinstalling drivers which didn't work.

I mean for the HTC, does the Samsung fast charge cable work to connect to the PC?
Does sound possible the phones USB port is faulty if you can't get any connection at all to the PC with multiple cables
Try changing the USB mode in developer options
Networking > Select USB configuration

Yep the genuine Samsung cable works when connecting the htc to the computer.
I've tried enabling USB debugging and switching between charging, MTP, PTP, RNDIS, Audio Source and Midi.. all of them come back with the windows popup

Unfortunately it is starting to sound like the phone is at fault
Still under warranty? (KNOX 0x0)

Unfortunately not. Well it's been rooted and flashed so I guess not.
Ordered a wireless fast charger so hopefully that will see me through and WiFi network for file transfers.
I reckon the USB port will need replacing but I'm not really inclined to do that myself.
Just noticed you said you flashed back to stock using a backup you made
Have you tried stock using ODIN and 100% stock files, using CSC to reset?
My dad has a5 2016 with the same issue, and no warranty. I bought flex + connector , replaced it and still nothing. No fast charge ( it takes cca 4hrs to charge it fully ) and no usb connectivity. I gave up on that
@ClowsTyle
Any luck? I seen your recent post in another thread and it sounds like you tried to replace the USB but that didn't work.
I'm having the exact same issue now. Device suddenly stopped fast charging, Windows does not recognize it when plugged into PC. I ordered a new cable to double check and also tried on different computers. I also tried reinstalling drivers, but nothing has worked.
Hi my is doing the same thing no Fast charge and no pc connection, did anybody find out what happen with yours ?
You have to change power ic s535 for s7 edge.
When usb gets moisture power ic will damage.
I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours
Same Issue
I've had the same issue for the past 3 weeks now and I've tried everything I know...
1. Tested cable and charger with another S7 and they work fine.
2. Factory Reset.
3. Changed the USB port chip.
4. Turned on "Low Battery Dump".
So far, the issue hasn't changed.
was this issue solved?
I´m having same issues whit my galaxy s7 active, I can not fast charge my phone no matter what cable I use, then noticed that evrytime I plug it to any computer it says the devicescan not be recognized, I´m about to buy a new charging port and install it, but I want to make shure this is not a software related issue.
I´ve tried several cables and several laptops/ pc´s
I´ve factory reseted my device and turned on low battery dump, wiped cache partition, and problem still there...
The charger could be faulty/damaged did you try a different charger?

Dial *#08# and select the first option (mtp and another option i am on a custom rom that seems to not have the *#0808# setting
I also have the same issue with my phone the phone charges but not recognize and also tried to change settings on phone and nothing? And my other samsung phone works and nothing wrong with USB tried to install smansung drivers on PC and still same issue.
I tried a different USB and nothing works and different ports on my comp.
My ports works with my other samsung phone so not sure why not with the S7?
Is the USB faulty?

A8 (2018) USB connection to HDD or memory stick

I've been having trouble connecting my A8 via OTG for some time. I have a Syntec USB-C to USB adaptor, which allows me to plug usb to the phone via OTG. However, this doesn't work any more (it did originally).
Sometimes when I plug in a device, the phone flashes device connected / device disconnected, sometimes it says usb charging, sometimes it doesn't do anything. I've tested the adaptors connecting them to the thunderbolt port on my desktop, and they work perfectly.
I've also tested the adaptor by using it with a USB-C to usb-a cable to connect the phone to my computer. When the adaptor is on the phone end, it doesn't do anything, when it is on the computer end it works perfectly.
Is there something I can reset or change on my phone to get this working?? It's driving me crazy.
Thanks,
Nick

plug your phone into your computer and change the connection type to MTP

otg access to usb and charge tablet at same time

hI everyone in regard to otg using Usb and charging tablet at same time, I have a fusion5 tablet and a usb hub the kind with 3 usb hubs and a power in with a micro usb male plug. and a switch for otg or charge. Ive tried using a potentiometer to find the magic resistor value between pin 4 (the id ) and pin 5 ground of the micro plug.
(thought i had it at one point but not sure) as could play a avi file while charging) However now most of the timee either accesses the usb or charges, I can get it to do both , but stops charging after 8 seconds.
Anybody happen to know if a specific resistance value works for both charging and otg.
I have seen another schematic but havent tried it.
It doesn't sound like the micro usb otg cable to me. I built one without a resistor and mine works just fine. Have a look at your usb settings. Some devices require you select your choice: usb otg or charging.

Thanks How do I look at my usb settings?. I think I may not have the proper resistor setting as will currently provide power to usb and charge at same time for a few seconds then stops charging.. I turn resistance up it will charge , turn it down and will allow access to usb.. i think have to find that magic number inbetween.

Depending on which phone and version of Android you have, the most recent versions of Android have the USB settings under Developers Options.
The USB OTG charging works differently from phone to phone. Sometimes you must plug your charger cable and the USB device you want to connect to into the OTG cable prior to plugging the OTG cable into your phone. This way the phone detects charging and device.

Yes that is what I have been doing . In developer options under Usb default , no charge option there, only file transfer, USB tEThering, MID, PTP ,and o data transfer
I thanks. However i believe the default USB option is charge as thats what it is when i plug in USB to a powered cable.
. As I said jt works for A short time using USB and charging at same time with resistor between 45K and 68k
then either stops charging and continues usb or keeps charging but gives usb errrors or cant access usb but continues charging.
Fusion5 tablet android 9
Update this works fine with unmodified USB hub or charge power and USB on my LG k32 phone but not on the fusion ta blet.
