Charging/sync irregularities

When I plug my Kaiser into my PC, the pc doesnt pick it up, and the phone doesnt charge. I've check the cable and port with other devices, and they were fine. I haven't changed the computer at all either. The phone says it is charging when you first plug it into USB, but the orange charge light does not come on, and after a while it stops saying its charging in the power monitor.
If I plug it into the wall charger, the light comes on and it charges as normal. The headphones also still work fine.
I haven't changed my PC at all, and everyhting used to work just fine. Does this sound like a hardware problem? Is there anyhting else I can do to test it?
If anyone has any suggestion I'd be grateful,
Thanks

If you've changed settings in the phone then make sure the tickbox under Settings -> System -> Power -> Advanced labelled 'When device is turned on, do not charge battery when connected to the PC' is unticked. Also under Settings -> Connections -> USB to PC, if you've ticked 'Enable Advanced Networking Functionality' then that can explain the lack of an ActiveSync Connection as some USB ports aren't up to that. What sort of USB port are you using (for example and old USB 1.1 port built into the motherboard)?

Suggesting the USB port itself is still OK (otherwise the charging problem would remain even though the audio pins are different to those used when synching.

Try it on another PC with Activesync 4.5 or WMDC 6.1 installed (according to which OS you're running on it). Otherwise if checking all the above configuration setting is to fiddly for you and you've nothing to loose off the phone, ensure your storage card is NOT encrypted and perform a hard reset. Read your manual or the xda-wiki if you need further info on how to do this.

[Q] USB charges off PC, but doesn't connect in mass storage mode

So this seems to be the same problem lot of people are facing and solving it by various means... Here is a list of things I have tried, but still not working -
1. connect to PC after selecting "connect to pc" in settings > more > usb connection
2. revert to stock rom and stock kernel using mobile odin and try to do (1)
3. restore nandroid from 2 months ago when it was working
4. cleaning with qtip (dry)
5. tried usb switcher app
6. tried newest jb 4.1.2 from eyebee's thread.
Any thing that I left out other than service center?

Usb Fix
I fixed two other Notes and a SII by this simple method:
Look into the microusb connector on your phone, and see if the pin in the middle is centered. If not, bend it straight (Carefully!).
Yes, I know it sounds stupid, but it seems people just slam the usb connector into the slot, bending it down... This causes the phone to charge but not to see the usb connection.
Hope this helps.

Checked... Its straight, but its placed at 2/3rd towards bottom - Not bent, but is placement itself is at 2/3rds..
Tried to bend it towards top, didn't workout...
What next?

By default its placed a bit down and forcefully bending it may damage the usb port and then you cant even charge it

Thankfully its still charging...

Hmm.. Something new you taught me, but didn't work.. Am I supposed to go "into" that mount usb storage screen and connect after I am in that "if you leave this page, we'll unmount" screen or before entering that screen?
Edit -
Never mind, tried both, both failed to work. I assume if it was working, I would have heard a beep from my laptop at least.. It didn't find any new device in both cases.

try using new cable. or borrow your friend's cable see if its working. its the basic to check thing but many forgotten.

Tried in office today.. No cable works... Tried 3 cables, one aftermarket one, one is of note's, one from nokia 5800 xpress music...
Didn't workout. All charges. No storage

you installed stock rom.. but didnt work..... so then it is not the firmware
you tried diff cable....but didnt work.. so then it is not the cable.
so then it must be your phone..
can it connect to mtp?

this may sound funny but it worked for me. take out the battery and the sd card. leave it out for a couple minutes. then reboot

You might be on to something here - It says Charging (USB) even if connected to wall socket! Should it say (AC)?

yes I am. even though the phone when normally booted won't be recognized by pc, but when in download mode, it usually does as I have had the same problem but that happens to me since I enabled the mass storage mode and then neither worked. mtp or mass storage.
when connected to charger, it shows ac and when connected to pc it shows usb

Gave to samsung service center today. Dumb fellows, they replaced USB connector in device, (thats what they said) but still its not connecting to PC. They didn't even flash a firmware. Just replaced connector and gave it back

I have the same problem here with my n7000.
Its happened after flashing ics roms. N7000's have some kind of faulty chips which causes emmc brick bug. But the issue we're having is a USB Brick.
Flashed many kernels & roms etc. but still no signs of life :crying:
Different cables & pcs, no luck..
As we are able to use mobile odin only, i flashed stock GB and sent for warranty. I always avoided to trigger binary counter so it was easy for me.
However, results were disappointing. Technician guy said that usb port is working and there is connection between both devices but something blocks usb connection. There were some unremovable files which shouldnt be there and they couldnt delete it as the section was read only accessible.
ADB isnt functioning too..
I guess the only possible way is to find a tech guy capable of replacing emmc to solve the issue from source..
Please let me know if there are any updates from your side.

Note 5 USB Port Not Working Except for Slow Charging

I have researched the issue of my Note 5just being able to slow charge via USB, and not be able to do anything else. I have tried all the proposed solutions I found, but can not fix the issue. The things that I have noticed to not work are:
Fast Charge: Cable and USB charging is detected, but cannot fast charge. I have tried the same charger and cable on other S7 edge, and it able to Fast charge. Fast charging is enabled in the battery menu
Connect to PC: Whenever connected to any PC, the PC shows “USB Device Not Recognized." I have the latest version of Smart Switch and the latest drivers. I have tried multiple computers and windows 7, 8 and 10. I have also tried to connect to the PC when the phone is in Download and Recovery mode and get the same error.
Connect to any OTG peripheral: Nothing is detected by the Note 5. Same cable working on other device.
Connect to Gear VR: When connecting to Gear VR, it gives the chime, the black screen with the little x in the corner appears for a second and then it goes back to the home screen.
What I have tried to do to fix:
Different cables/chargers/USB ports
Checked if any of the 5 pins are broken in the cable
I have lifted the tongue of the charging port in the phone via tooth pick
Done a factory reset
Any insight on this issue would be appreciated.
Thanks

Have you tried different 2A charging bricks? A regular 1A charger would still take a long time to fully chargeNote5.
You could also be looking a bad USB-port or a faulty battery, both of which would be covered under warranty provided no large physical damage is evident on your device.

Thanks for the reply. I have tried the original Samsung charger, 2A, 1A, and 0.5A charging bricks, but the phone shows either Cable or USB charging.
About the faulty battery, will that cause the PC and other peripherals to not detect the phone?

Same happened to me two days ago. I restored an old backup, done a factory reset and restored my actual rom again and problem solved. Idk what the problem was related to. Try wiping cache again, maybe it helps.

I have done a wipe from TWRP, but the issue was not fixed. I can not change ROMs etc as I can not connect the Note 5 to the PC via USB cable, even in TWRP.
Was your phone just not Fast Charging, or it wasn't being recognized by the PC, etc.
Thanks

Actually y have the same problem, unfortunately I don't have root access.
Try the app called USB host check, maybe they can help you.
Is not possible to me because the PC don't detect the phone connection and obviously I can't make the root.

I have the same issue tried the same fixes. No luck. Have you found a solution please?

I ultimately had to change the motherboard. Changing the charging port did nothing.
However, I suspect it was a corrupted firmware. If you can somehow flash a latest stock firmware and check, that would be great.
In trying to fix the firmware I had corrupted Stock ROM. Since I could only use WiFi to transfer files via WiFi FTP type apps, and I didn't have a working ROM backup on my phone, after the Stock ROM was corrupted, I could not upload any new files to flash with TWRP so I had to change the motherboard.

If you see the "USB Device Not Recognized" message when you connect to the PC, then I think the charging port is fine. It is some issue with the firmware as phone is not able to provide the correct PID and VID to the peripheral devices to identify itself. The charging port and its circuit doesn't hold that info. If possible, try to flash a stock firmware from TWRP as ODIN will not work (I am not aware of the exact procedure). Just MAKE SURE you have make a backup of your current setup and leave it on the phone as if you have an unsuccessful flash, you will not be able to use ODIN or ADB as your cable will not work.

Same problem but with 2 phones
My note 5 and my friends S6 edge were totally fine, but on our farm (which now i found that has a low voltage eccentricity at around 190 V), we put them on my charger (the original charger that came with the note 5) and both of our phones now have the same problem, they charge very slowly ( up to 6 hrs for a full charge) and are not detected by any pc using 3 cables that work with other phones normally, the charger itself is okay, and works well with other devices (at home of course, and fast charge works with other devices).
I have tried everything, restart, safe mode, delete cache, charge while its off.. with a number of chargers and cables, it does not make any difference.
If any one knows how to fix this, your help is appreciated.

Mine is a little different, My Note5 is not charging at all via USB but works fine with wireless charging. In short, even if i plugged it via PC or via charger, it does not charge anymore.
But I noticed something, when I am in TWRP recovery, my USB OTG drive is readable and when i am in download mode, Odin reconizes the Note5's COM port. I did a reflash of the stock ROM hoping this will do the trick. but it failed. still does not charge at all via USB.
Can anyone help me with this? Thanks in advance. all answers appreciated.

this seems like you have faulty usb port .

USB connection Issue to PC

Hi, My phone is showing these symptoms :
If I connect it using USB cable, no USB icon shows up in status bar, PC does not recognize any device connected to it(with or without driver you should be able to see a USB device connected to it) also it wont even charge!
Phone charges fine with charger
If I turn off phone and connect it to PC it will start to charge
Holding volume up and connecting to charger will result in LED turn blue and a black screen but still no USB device shows up in PC for fastboot
If I go into USB Preferences and connect the USB to PC everything is grayed out except enabling charge connected device
what I've tried :
Use different cable
Use different PC
Use different OS(windows10/Linux)
Reboot phone
Removing SD card and SIM card
Factory reset phone
Clean USB port
My phone is using latest Android pie Build 52.0.A.8.14, developer mode and USB debugging is also enabled.
I would appreciate if you let me know how to resolve this If you think it's not a hardware issue
Is there any way to install TWRP without having USB connection to the phone ?

If you don't rely on unlocking, usb data transfer, etc it is fine

I know this is a old thread, but
I have a similar issue, I need this phone for debugging purpose, and I "fixed" it by turn the usb-c around........
Just like the old usb.
I don't know why. I already tried multiple cables, all have "one side connection", it seems it's phone's hardware issue. But I'm not sure.

That's not the case for me, looks like some people are telling this has happened for them after updating to 52.0.A.8.50

This problem started yesterday and somehow my SD card is not recognized anymore, it's asking to reformat it.

Only it doesn't want to connect to finder on my Mac, I have yet to try a windows pc.

USB data transfer not working.

So i bought a used A2 for 5500 INR.
At first i thought it was a bargain but soon it turned out to be a nightmare.
The phone is full of bugs.
Worst one is that the phone only charges through the usb port. No data transfer of any sort. like an old nokia pin charger.
OTG doesn't work. It doesn't connect to the PC.
Whenever I plug in the OTG/connect it to pc, the usb options are all greyed out (same in the developers options default usb preference).
I can't even use Gcam now bcoz the PC doesn't recognise the device at all, so can't enable Camera2api, can't root, can't install ROMS... can't even buy a new phone cuz i have no money ???
turns out my phone also have the slow Emmc issue ?....read speeds are okay but write speeds are very slow... specially Random write (~10mBps).
I read many people have faced this issues. All those Posts are old, has anyone found a solution.
