Donno if its the regular case of 'bad usb port'. It's happening only when I'm charging with specific car charger (1A, output 5V) sometimes its charging fine, sometimes I notice its stop charge and the icon of battery is blinking/flashing...
I've tried to clean the usb cable and port from dust, maybe the cable got some dust into it?
Also I've notice that the temperature of device goes down to 22°C when its happening...
At any other chargers (include othe car chargers and other wall chargers) there is no problem at all...
What could be the reason of this specific car charger (it used to work without any problem the last few months ago)?
High/Low voltage? Dust?
maybe other problem with my device? (Battery/something else)
BTW - when I plug the charger out when its happening its stop blinking.
could you please give us a screenshot?

From reading your post, it only happens with that one charger....any other charger works as expected?
That being the case.....it ain't your phone or the USB port/board in the phone.....
Chargers DO fail, and from my experience, dc to dc step down transformers and circuitry (the type in your car charger) have a higher failure rate than their ac to dc (mains) equivalents. ....
Time to buy a new car charger methinks

@wishmas7er - which screenshot mate? when its happens all I see is blinking/flashing battery icon, without any other message or something else about it.
@keithross39 - correctly mate, all other charger (any kind of them) works just fine.
Yeah seems like its the car charger problem, just first time i've notice it...
Thanks!
BTW - the reason of 'bad touch' while charging with some generic chargers is because higher amperage then should be to this device's battery? or other reason?
As long as the amperage is not ludicrously high or low, the only noticeable difference would be the charge time.....other than that there should be no noticable effect....

Battery Icon Flashing with Samsung Galaxy S4 Car Charger
I had the same problem charging my Galaxy S4 in the car. AC charging works fine but when plugged into the DC car charger the battery indicator icon flashed rather than showing the lightning bolt.
I purchased a higher voltage DC charger adapter, same symptom.
Finally I swapped out the USB-to-micro cable and now it works fine. I suspect that in the car the phone gets jarred over time and it wears down the micro-USB connector.
It's not just you fella........
The micro USB socket idea is (imo) a pathetically fragile arrangement for what the manufacturers intend it to do. I've repaired two phones with worn out sockets, and judging by what I am reading on XDA, it is an issue that is getting more and more common.........

So I'm experiencing the same blinking problem with my note 4. Each time the lightning icon blinks the phone vibrates in sync with it. And ithe galena with all charges. I have to keep unplugging and replugging ...and OCCASIONALLY it charges. I don't know what's the problem

I have same problem with my nexus 4.
After some googling I came across an app called Ampere.
This app tells you how much rate of current your battery is charging at.
So what i found is that when phone gets old the battery doesnt hold up charge as before. So the charge rate becomes slow. The nexus charger is rated at 1Amp and at the time of charging is able to provide low current than the rate at which the battery is draining. So the Android gets confused between charging and discharging.
For eg: if phone is charging at 300mA and draining at 350mA.
Also the battery draining rate is constantly changing. So when its greater than charging rate phone shows discharging and if less : charging...
Fix: There are three fixes which i can think ...
1) Get a higher Amp rated charger...
2) while charging close most of apps , dont play games , switch to a lower gen network like 2g , close wifi , close data which will reduce the discharge rate of the battery.
3) Get a new battery.
So I'm experiencing the almost the same blinking problem with my note 4. Each time the lightning icon blinks the phone vibrates in sync with it. It won't come on it won't reboot I've tried everything BUT replace the battery because if I plug it up it'll vibrate and blink but nothing else works. It's completely black when it's unplugged.
I have an unrooted Samsung Galaxy Tab 2 7.0 wifi which is running the most current updates. I plugged it in to charge and the next time I went to use it it would not turn on. When I plug it in it does not show a charging indicator. I have tried to hold the power button and volume button alternately and every combination possible with no results. I have plugged it in using on the USB cord to see if the AC adapter was bad. I have unplugged the battery for a period of time as I have found elsewhere with no success. The only thing I have not tried is a different USB cord. A final bit is that recently when charging with the device off the battery has been yellow rather than green. To me this points toward a battery failure, can someone enlighten me as to what could be wrong with the device?
So I pay £45 a month for my Samsung galaxy mega 6.3 I've had it for a month and a half now and its a lovely phone, works well and everything, however all of a sudden I plug my charger in and it constantly flicks between charging and not charging (the little lightning bolt symbol appears and disappears constantly) whilst the cable is firmly plugged into the phone, this is when the screen started to flash at me and click on things I haven't touched , the most common thing it does is switch on driver mode , the back and options button flash at me and the screen switches on and off rapidly, I've reset the phone and tried a different battery and still the same result, its not as bad now, when I put the charger in this time the screen doesn't go weird it's fine its just my phone will charge but after 5-10 minutes it will stop charging again and I have to go and unplug it and plug it in again, this is seriously annoying so is it a malfunction with the phone? Is It something I've done? Is there an easy way to fix it? I need help please!
Is that the same when you charge your Mega through USB cable from PC? If yes, then it is phone's hardware problem, but if NOT, I would suggest to change charger.
Charging from PC is also possible, but the charging current is about 1/4 th of current from dedicated wall socket charger - the phone is charged although much less intensively.
Nominal charging current from wall socket charger is approx. 1.9 amp so if you need to find new one, choose wisely and accept only charger with 5V 2A specs.
I just bought a Samsung Galaxy S6 SM-G920V. The phone does not turn on unless USB or wireless charger is connected. When any charger is connected, the phone charging meter displays 99% and charging. But when the charger is unplugged, the phone would just turn off. I bought it with the problem hoping that the battery was the problem. However, I already installed a new battery but the problem persists. Do you have any idea guys?
Any help guys??
Could anybody help please??
Any ideas?
Is there any magic word to have people replying to my posts?? I guess, I just can say: HELPPPPP!!!
Hello, my tab s3 has developed a issue,
When I plug the charger in it registers that the charger is in then it goes off as if the charger has disconnected, then comes back on again.
It only states that it is charging it no longer says fast charging, I have tried various fast charger plugs and cables all which work with my note 8 but not the tab s3.
I have tried deleting the usb cache and cleaned the port with specialist contact cleaner.
Any suggestions would be greatly appreciated
