s7 behave strange during usb cable charge - Samsung Galaxy S7 Questions and Answers

Hi all,
i want to ask if someone has already encountered with following behavior:
Suddenly, without any apparent reason, my Samsung galaxy S7 stopped charging via USB cable.
note on the side: I mostly charge through wireless.
I tried factory reset, i tried different wall charger, cables, cleaning of usb port.
What is strange is that when i connect phone to usb cable the screen lights up, but charging does not start. Data transfer to pc through usb works fine too.
Now i have discovered that when i put my phone on charging pad (wireless charger) and i connected a usb cable while charging , phone switched without any problems from wireless charge to usb cable charge and then continues charging.
wtf?
any thoughts what to do next?
Thank you!

I've never charged wirelessly before but that sounds like a hardware problem to me. You'll have to return it to your mobile carrier and get a replacement.

Unable to Charge HTC TOUCH PRO Via a usb/car charger

Hello,
I have a VODAFONE BRANDED, HTC TOUCH PRO phone and it has started playing up suddenly.
It would charge when connected to a pc, car charger using a usb cable or using any mini usb charger. all of a sudden it has stopped charging with any other charger except its own htc wall plug charger.
I have tried a hard reset and still no joy.
the charge via usb is unchecked and it charges when connected to a PC.
However it doesnt charge with the following methods which used to work earlier
1. Motorola charger - mini usb
2. Using a usb cable and a wall output with usb
3. car charger with a usb output.
I have a htc audio out connecter. when i connect the connector, and then charge via usb it works in the car and from the wall.
is it something to do with the pins on the cables and on the device??
I used to get a menu asking the sort of connection that i needed (activesysnc, data etc) when connecting to the car charger earlier, it does not come anymore.
Its frustrating cos i travel a lot and find chrarging with usb cables the most convenint in the car, office or else where.
Could it be damaged pins on the device??
Any ideas/suggestions will be highly appreciated.
Many thanks

Its prolly pins because the mini USB is not a perfect fit for the HTC audio jack. I would use your HTC adaptor and run the USB through that.
Something might be blocking a less than 1000mah income charge..
On low battery (as in dead-battery) you definately need a wall-plug charger. Under normal conditions the USB car charger or laptop would be fine.
Since you hinted the use of the audio jack I most likely is a bad connection on the USB pins. Did you take a look at them using a magnifying glass?

Ur problem solved? I am facing kind of similar problem... Now my Touch HD can only charge using USB cable through computer.. it will not charge using any other external AC adapter.. very strange huh?
100 % fix
I managed to solder the black negative wire to the usb housing of a male usb mini and now it charges without any problem. The housing is used as a substitute for pin 5 that is negative because it has a metal shield as standard.
to make it easier for some noobs, just get a usb female to a usb mini cable and cut it off and solder the negtive black wire to the shield cable around all the wires. AS standard all usb cable have this shield metal that conects to the usb housing.
This is a FIX if you have managed to break the pin5 when inserting the stylus in the usb rather than the RESET button.
I had a weird charging issue with my AT&T Fuze as well...
The phone would charge fine (wall or PC USB) until I got some kind of notification on the phone (missed call, e-mail, etc). Then it would stop charging. Often when it was on the charger and on, the battery would run down until the phone shut off. Then it would start charging again. I would put my phone on the charger at night (and on) only to come down in the morning to find my phone turned off and charging because the battery had run down!
Shortly after this started happening I also started to get "storage memory low" messages. Coincidentally, since I freed up a bit of the storage memory (cleared IE and Opera history) I have not had the charging problem...
mini-usb problems with charging
This is the 2nd Fuze that has problems with the mini-usb connection and charging.
Slight forward pressure is needed to get a good connection. This happens with two different cables, two different car chargers, and three different HTC usb adapter dongles.
My phone is usually plugged into my computer or my car charger, unless I'm carrying it. I keep the screen lit when on external power as I use it extensively as a PDA. It's real obvious when I lose the power connection, as the screen blanks shortly thereafter.
Do i need to send my fuze back? since I havent read a solution. I dont think its software but i turned on charging through usb and now its the only way to charge. No chargers work? Grrrr. Batterys and chargers are good. This happened to my last fuze.
not to be a prick or anytihng, but have you checked the battery settings, there is a checkbox so it doesnt charge when plugged in - i've knocked this on a few times myself
the OP already noted that that option was not checked. Please read a little before that.
My car charger sometimes need me to move the wires around abit before it starts charging. It seems to be more like a pin issue.
Mini USB Charging Problems
I had the same problem.
I just solve it by using other mini usb cable.
Now it charges.
HTC Touch Pro Charging via USB Problem Solved
I can't believe it was that easy! You are correct; There is a check-box that will disable charging via USB if the unit is powered on. "Systems/Battery" I have been putting up with this for months, but never took the time to try and solve it. Sheesh!

[Q] Infuse 4g wont charge or conect to the computer

Suddenly as it usually happens it stop charging or connecting to the computer. I tried 3 different cables and wall charger. The only thing it does if I turn it off and then plug in the charger or computer cable it will start but it won't charge nor it will not connect to the computer. I think it's the port.

Try uninstalling your drivers for the phone and reinstalling them. That should solve whatever problem you're having with the phone not charging or connecting to the computer because it sounds like all of the drivers needed are not present.
I had this same issue. Mine would charge ONLY if the micro USB was plugged in ever-so-perfectly. The slightest bump would knock it loose, and it would not charge. I ended up buying spare batteries on eBay that came with a battery charger for around $12. Not the ideal solution, but I always keep a battery charged just in case it decides to die. I can get an upgrade in January, so I'm waiting this out.
Also, if you need to connect to computer, I just unplug my micro SD card, and plug that into an adapter and transfer any data that way. I know there is a website that will fix / install a new micro USB port on the Infuse. Sorry I don't know the link off hand, but I have read a few others that have had similar problems.
Best of luck!

[Q] Nexus 5 won't charge over USB

Hi guys, so I have a stock N5 and it won't charge over USB or AC unless the phone is turned off. I've tried to factory reset with no luck.
My current theory is that something's up with android itself, instead of BIOs. Has anybody else experienced anything similar to this?

when I first turned on my N5 and connected it via USB to do various root related stuff, my battery actually went down with each reboot. Even connecting to the AC cable charged it pretty slowly. But now it's charging fine via USB or AC (although the charging speed with USB does seem a lot slower than my previous phone, Galaxy S3)

Yeah, the phone charges over AC slowly here too, but strangely enough it won't even make a USB connection with a computer as your phone did.
Same Problem!
Hi,
I'm having the same problem.. I could use it well and charge it over USB nicely but know it only charges when the phone is turned off. You could solve the problem??

[Q] Technical assistance. Charge port issues

Hello, back in January I got my charge port replaced on my Galaxy S3, but now I'm having a weird issue with it. When I plug into the wall charger, the connection is very loose and it's difficult to get a good connection. The surprising bit is that my phone charges perfectly when it's plugged into a car charger, or my laptop USB port. In fact, I'm charging my phone overnight by leaving my laptop in sleep mode. Also, data transfer (music, photos, etc) seems to be unaffected.
I don't know if this is a charge port issue or a software issue. I'm running the latest stable LiquidSmooth Kit-Kat ROM, so idk if that's affecting anything. I have tried other wall chargers (with connected cable, not separate) and the charging is still very loose. I also ordered a brand-new charger (with USB port) and I still have the same issue. Please help.

USB-C Port Issues - "Charging Connected Device via USB" is a Constant Notification

USB-C Port Issues - "Charging Connected Device via USB" is a Constant Notification
Back info: So I charged my Pixel 3 once via the USB-C cable that came with it about a month ago, and I also tried the USB-C headphones too (around the same time) and both of these work just fine. I've since been using wireless charging and Bluetooth headphones.
I just got the pixel stand and noticed about 2 days after using that I keep getting a notification that says "Charging Connected Device via USB" even though I'm not using the USB-C port. At first it went away, but now it is staying through reboots and even shows up in safe mode sometimes. So I tried connecting the USB-C cable to the phone to see if it goes away, and I notice the cable doesn't charge the phone. Now if I power down the phone and plug the USB-C cable in one of two things will happen, but it depends on what side of the (reversible) USB-C cable is facing up:
1. The phone will start to charge and continue to charge if I hold down the power button and turn the phone on.
2. The phone will turn one when the cable is connected, but not charge the phone.
I don't think this is a hardware problem because I can use a USB-A to USB-C cable from my computer and it will charge/transfer files no matter what side of the USB-C cable is up. I also don't think this is cable or charger issues because I've used two different USB-C to USB-C cables and chargers (the set that came with the Pixel 3 and the set that came with the Pixel Stand).
I have also tried the USB-C headphones again and those are not really working either. I got them to work once by activating the Google Assistant as I was plugging them in, and they would continue to work after that until I plugged the charging cable back in. I tried the headphones again after the power cable, and they stopped working again. I now notice that the "Charging Connected Device via USB" will show up when I plug the USB-C headphones in one direction and not show up if I flip the USB-C port over.
There are some people with the issue over on Reddit, but no one seems to have a fix. One person said that a factory reset fixed his issue, but I've so many 2-factor authentication apps, that it is a real hassle to do a factory reset.
Well, the overall description of your problem does seem to point at a HW problem, since USB-C cables should be fully reversible on a hardware level.
Looks like it was corrosion.... I took a small brush to the port and cleaned it out. I cleaned it over clean surface and no debris fell out, so it is kind of concerning that corrosion would build up after halving the phone for just under a month.
