Just as title says, 10 days ago i used my s20 exynos (g980f) on some windows 7 pc for wifi access, and after that i couldnt charge it. Charger works with another phone, cable works when connected to laptop, but together nothing.
I found that entering safe mode helps, did reboot in safe mode, rebooted normally (had to reapply theme, wallpapers, set default apps), and charger worked again.
The same thing happened yesterday, using the same pc. So, i'm just asking if anyone else experienced the same? Maybe someone could try usb tethering and charging afterwards?
Btw, it doesnt matter if i enable or disable fast or super fast charging... Also i think i was using ATCT (or ATD3) back then, now i'm on ATD5.
Try setting default usb setting to charging only and see if that yields any results

Interesting problem I have had on and off. When I plug my phone into my desktop, it will connect normally, then a few seconds later it acts like I unplugged it. It's not the rom as it does it in recovery as well(both with usb-ms activated and without). I have HTC Sync installed. Rebooting either the computer and/or phone doesn't fix it, it just goes away after awhile and starts working again. I've experienced the problem FAR less when connecting it to my laptop, it will typically work there and not on my desktop when the problem crops up.
it's like this problem but it's not constantly http://forum.xda-developers.com/showthread.php?t=711616
-Edit- the device also doesn't show it's charging even when it 'disconnects'
I have the same problem. just keeps discontenting over and over it sees it for a few seconds then disconnects reconnects then off again.

Mine doesn't reconnect, it 'disconnects' and stays that way(as if i unplugged it) until i actually do unplug it and reconnect it.

I was having the same problem on my MacBook until I realized the MacBook must be plugged into power. Once plugged in everything was good. I wonder if the Evo demands more power through USB then other devices.
Yeah, sounds like a power issue to me. If you're using a USB port on a hub or on a keyboard, try one on the PC itself. Also, it could be a slow USB port or a bad cable if you are continuing to have issues. Try another computer if you can, and if you still have the problem try a different cable. Still have the issue, reflash (if you're running a custom rom) or contact Sprint for service.
Same issue here, but on a desktop PC (Dell Studio XPS) using the front-mounted USB port (not a hub). Keeps disconnecting/reconnecting, but often takes 10-15 minutes between cycles. Using stock ROM (for now, at least). Will try other ports & another PC and will report back.
Already tried different ports, only motherboard ports
Rom doesn't matter as the problem exists in both android and recovery
Don't have a different cable, however the same cable will work fine on my laptop then not work on my desktop

If it works on a laptop, but not the desktop, then it appears to be an issue with your desktop. Any other USB devices doing it?
I would check your motherboards manufacturer and make sure you've got the right USB drivers, a bios update might be in order as well.
But before all that, I've got an idea. First and foremost, try this:
Go to device manage (either from control panel, right-clicking my computer and going to properties, or searching for devmgmt.msc in the start menu search.)
Navigate down to Universal Serial Bus controllers, double click on USB Root Hub (you probably have 1 for every USB Port, so you may have to do them all.)
Click on the Power Management tab, and uncheck the "Allow the computer to turn off this device to save power." check box and see if that solves your problem.
i had this issue on my hero. it was corrected for me after i did a wipe of data and cache. i restored from titanium afterwards. YMMV
good luck
one thing you might try is disabling sense and using the android launcher. then reset the phone. once it boots up try and connect it to your pc. This was how I got mine to connect. when I was using the sense launcher it somehow blocked that options screen and the default I selected wouldn't stick. once I got the connection to my pc working this way I was able to re-enable sense and it's worked perfectly ever since.
I do not take credit for this fix, someone else on here told me to try this n it worked perfectly.

it was nothing with the rom, since it was doing the same thing in recovery.
it turned out to be the short little usb extender cable that was going a foot and ahalf from behind my pc to the side so i could plug it in easier.

I can confirm this works on my HTC Desire - had been racking up my brains for the past couple of days now with no solution! Thanks a lot. This is on PC with Win7 Ultimate.
Hello, I have been looking everywhere for months on a solution to my problem and though I have been read about many similar problems mine is a bit different.
My s3 will not connect to any PC. No notification on the PC or phone is visible. The last time it worked I was flashing from CM10 to stock via Odin then update through kies to stock 4.1.
*Note: I was non cm10 with ktoons kernel using fast charge(for about a week) I noticed my phone was getting too hot while charging which was what really made me move back to stock.(plus cm10.1 was not out and I wanted to try a stable version of jb)
The original cable that came with my s3 broke in about a week. So I was using an old mytouch4g charger/cable for a while. My my touch 4g cable was all broken too but it worked. I remember that when I wanted to use Odin to flash to stock my phone would not be detected (though it was working before.) So I asked my sister for her cable. It worked and I flashed to stock, booted to Ubuntu on my PC to set it up. I noticed the the device Id wasn't showing (it did appear a few times but dissapeared pretty fast) after about 2hrs of trying to get it to work nothing. Booted to windows 8 and it wasn't being detected either. So since then I,ve been trying to get it work.
Problems I'm facing:
-No USB connection on any computer.(but charges)
-No USB notification
-slow charging when connected via wall charger(sometimes it won't charge at all)
-Charges normal when its off.
-Charging led stays on for about 15 to 30 secs after being disconnected.
Things I've tried:
-different pcs
-Many different chargers (same slow charging and battery led weirdness)
-Many diff USB cables (including my new Samsung cable that came with my nexus 10)
-Formating my PC.
-Flashing diff ROMs/kernels (currently cm10.1 w/ stock kernel)
-Factory reset.
-USB debuging (enabled/disabled)
-Download mode (USB not detected)
-Removing SD card.
-Booting with phone connected.
-Cleaning connector with a tooth brush(I think its still dirty)
-Kies USB troubleshooting
I also notice my battery is draining way faster. 100 to 0 in like 7-8hrs with like 1hr-2 onscreen time.
So I am officialy giving up, and will continue to use my phone and flash ROMs till it dies, but before I do I wanted to hear what XDA has to tell me.
Is my port damaged?? Any other ideas that might fix it?
Please help!
I have the same problem odin sees my phone in download mode or a camera but not as a phone. When it does connect I get a popup on my phone saying service pack 3 not found. Im reinstalling xp ill let you know if it works

Hi guys,
My GNex has a problem. Many users seem to have a similar problem but theirs seem to be hardware related and I'm pretty confident mine is software related.
It started a few months ago when my GNex wouldn't charge through the wall charger. I was on a trip with my friends so I didn't have access to a pc and wasn't able to troubleshoot further. The charging icon would appear when the phone was off but when I turned it on it didn't charge. I played around with the phone for about two hours, rebooting, Googling for solutions, changing the USB connection modes in the Storage settings. When I changed from Next Launcher to Stock launcher and rebooted everything was working fine again. However I think it was only a coincidence. Then the problem didn't occur again until now and this is why I think it's software related. If hardware would have been broken the problem wouldn't just have fixed itself like that.
It happened 3 days ago but somehow fixed itself again. I was troubleshooting the issue with my GNex connected to PC and installed Nexus Root Toolkit by Wugfresh. During install my phone rebooted on it's own and suddenly USB worked perfectly again!
However yesterday I forgot to charge and my GNex died. On reboot the issue was back.
"Symptoms":
Phone won't charge with any wall charger (and any cable) unless off
Phone will charge through USB in any mode but PC will not recognize it and install it as unknown device.
USB Debug Icon and Connection Mode notification do not appear in status bar upon PC connection
OTG doesn't work and apps like "Stickmount" do not detect external drives
Attempts:
Gently bending the "tongue" inside the micro usb on the phone in case there is a bad connection
Reinstalling drivers on PC
Rebooting device in different modes including fastboot
Using different batteries
NOTES
This problem started after latest 4.3 update. It has only occured after battery completely runs dry. I have 3 batteries (a bit excessive I know) and an external battery charger so charge is not the issue, I just really want to understand what's going on with my phone.
I'm not ready to Factory Reset or replace the USB port yet, those are last resort options to me. Any other options, especially software related, are very welcome. I am on stock 4.3 only rooted and with CWM recovery.
In Testing menu (type *#*#4636#*#* in Dialer) under Battery Settings my phone also says Charging (AC) when connected through USB. Hope this helps.
Been Googling around for two days now so I decided to make my own thread. Any help is appreciated. Sorry for this very long post.
Fixed it! Tried bending the tongue inside the micro usb again, forced much more this time, everything is working again, for the moment
Hello all,
I have a nexus 7 2013 and I am looking for a kernel that supports otg plus charge. Now, I know elemental x (by flar2) and a few others have this but the ones I have found do not support hot swap, or unplug and replug without rebooting. I am pretty sure Timurs kernel supports this but he wants $36 to buy it and I would rather not spend the money without trying it out first. Specifically, I have a fixed in-car installation and a febon100 UVC video grabber to display a backup camera. When the car shuts off, the febon will be disconnected from the usb side of the nexus, and the only way to reconnect it is to reboot the tablet with power connected. Anyone have any ideas? Thanks for the help.
Ok so I figured part of it out. After the device looses and regains power, these two commands simulate the usb disconnect and reconnect and seems to work (only tried it a couple times)...
Code:
echo "2-0:1.0" > /sys/bus/usb/drivers/hub/unbind
echo "2-0:1.0" > /sys/bus/usb/drivers/hub/bind
However, I have another issue. I am using the elementalx kernel on android 4.4.4 (currently on Carbon rom but have tried stock and other roms as well with same outcome). When the tablet reboots with the otg cable connected, it does not charge when it first starts up. To charge it, I have to physically unplug and replug the cord in the nexus. Any ideas?

Just use tasker to run the commands at startup...
Does this set of command still work with lollipop? I just tried a few times and it seems to have made no difference.
Thanks in advance!
Yeah im in the same boat. Soooooo many problems with this ****ty tablet. Knew i should have installed an iPad. They said this is the 'best' of android. It's ****ing terrible. People who are thinking of installing an android into your car? A word of advise. Dont do it.

It's been almost a year any way to accomplish charging without having to physically unplug the OTG and plug it back in. Im have timurs kernel but I want to use elemental so I can use marshmallow. Timur accomplished it somehow. Someone has to know how.

It is actually trivially easy to accomplish - on any kernel - it is called Qi Wireless Charging.
Android 6.0.1 kernel Quanta-V7-Flo with 'USB Host Mode Charging'

Test results for Android 6.0.1 Stock + Kernel 'Quanta-V7-Flo' with active 'USB Host Mode Charging' and inactive 'fast charging' (N7 is only is use when its connected to the USB Power):
Ampere values checked with one of the cheap 'USB Charger Doctor Voltage Current Meter Mobile Battery Tester':
0.45 A for N7 only
0.61 A for N7 + USB Ethernet adapter
I don't use the N7 in a car setup but this should be important for such setups:
-If the USB Y cable is connected before powering on the N7, the USB device was usable in Android after startup without need for reconnecting the USB cable
-If the USB was unplugged and reconnected the device, it was usable in Android
-Important: If the N7 goes to sleep, it can't recover the USB charging and USB devices after waking. You should set the display timeout to always on, which is right for a car setup or am I'm wrong?
I'm happy! :good:
I tried quanta. It does work except for on initial boot. Have to unplug and plug it back in to charge. Then it works fine turning the key on and off for power. However it doesn't mount the OTG devices again without unplugging it and plugging it back in.
Edit: I also have another problem was at work and didn't have time to add it. But my Nexus thinks it's still charging after disconnecting it from power supply through the OTG cable. When I turn the key off it quits charging for about 1 second then switch's back to saying it's charging again and continues to say it's charging even after cycling the key on and off. Only way to fix it is to disconnect the OTG straight from the tablet and plug it back in or boot it into recovery then back to system. Has done this thru multiple roms and kernels. Only kernel it doesn't do it on is Quanta. The thing is it didn't use to do it at all no matter what rom or kernel I was using. I even went as far as to change the charging port board cause I had another one in a old junk Nexus I have and still didn't fix it.

I've used it before but not on my current setup.
Assuming one of these kernels provides OTG + Fast Charging, what are the options for the Power-Down + Deep Sleep, then Power-Up + Wake?
Hello,
I have a Galaxy Note 10.1 2014 Edition (P605 3G+Wifi) that began to stop charging when the screen goes off. Yes, it's weird but not uncommon. All the topics I found (like this - https://forum.xda-developers.com/showthread.php?t=2775833) are fixed by using the original Charger + Cable, which I already did. I even purchased from Samsung a new cable, just in case, with no luck. I also have opened the tablet and resettled all the connections (the vga flat cable and the battery connector). No luck either. :crying:
The only way I have to charge my Note is by installing an app that keeps the screen on while charge. Than it takes 10 hours to charge (with wifi, bluetooth, etc off, and brightness in the lowest) 100% but at least I can keep using my tablet.
EDIT: It also charges when turned off, but the charging speed is as slow as when on with the screen on. Only when on, I connect it to power, it starts charging, the screen goes off and, after a couple of seconds, screen comes on again and its not charging. Its like someone has pulled the charging cable.
I am tired of this and would like to have a definitive fix. If I buy a new battery, will it be fix? What is exactly the problem here? Reflash the ROM will it fix? Does any one knows?
Thanks for the help.
A full wipe and reinstall would likely fix your problem. I've been in this problem once, where the device charges under any condition, but it does so s l o w l y, no matter through what connection. Solved this by doing a NAND wipe through ODIN and re-installing all with that too.
What's your current ROM and bootloader? What kind of modifications have you done?
I'm running 5.1.1 stock rom with root only.
Will have to try that solution and reinstall all my stuff. Thanks.
Good news. Problem is solved.
So I wipe data... no luck, same problem. Download ROM and ODIN, entered in Download mode, connected the USB and... Nothing happened... only the tablet starting charging but the OS didn't detected anything. Tried other PC, same result. So the problem must be on the USB Port.
Checked this video - https://www.youtube.com/watch?v=tZcwHd0wy0M
Opened the tablet and took off everything like shown there. Including USB Port, flat cable and battery. Reassembled eveything and... voila... problem solved.
Thanks.
