NOTIFICATION: Android System USB Connector Connected/Disconnected

[AliJ2021]

Hi, I am having an immense issue on my phone, which also many other people are encountering I saw online as well. I keep getting a non-stop silent notification which says USB Connector Connected / Disconnected. I have a A51 phone and since 3 days this is going on.

I saw many other people encountered this issue. I have tried many of the proposed solutions but in vain. Here is a list of things I did to tackle it:

-Discharge my phone battery to 0% then full charge to 100% with my original battery charger and TYPE C cable.
-Cleared cache and date of USB Settings
-Cleared cache of Android System
-Boot in safe mode and cleared cache of USB settings
-Master reset
-Wiped cache partition in recovery mode
-Downgraded to previous firmware
-Cleaned USB port with a plastic toothpick
-Put the phone 20 hours in rice and even used hair dryer
-Enabled developer mode and change USB default connection to phone charging only

I tried all these but in vain. The issue still persists. I have heard that even after changing the USB port, the problem comes back later. So, it is not a hardware issue then!

Please help...

The answer is to go to notification settings for usb connected and put it on silent then to activate minimize notification it works for the dark screen too

Same issue with Galaxy A70. It starts happening after I connect the phone to a charger or PC. Sometimes even rebooting doesn't solve it.... Very annoying issue.

This works to hide the notification but the notification still continues to pop up if you go to your notification history. So my question is, is the device going to drain battery or run slower because of that notification constantly going 24/7?

This is Scam by Samsung they wantedly create bugs and issues in Samsung mobiles and make us to buy their new products and throw our old devices, I have seen various types issues in only Samsung devices not in all other brands that al of them are only software issues which wantedly saumsung doing this cheap tricks to sell their products.

It definitely drains the battery to some extent because the screen gets turned on every time this notificaion is displayed while the phone is locked. I've already cleaned my USB connector mulitple times but it's still happening after charging the phone almost every time.

I'm having the same problem with my s10e. I noticed the problem after a system update. Do you know if your problem started after a system update?

@Jakobi 

I'm pretty sure it was from a system update. My phone did it for a couple days and then randomly stopped. Then started back up again a few days later for a few days and then stopped for good. Hasn't happened since. Hopefully the same thing happens for you. 

You can try going into your "Samsung members" app and checking ur inbox for notices to see about any messages u received and then also try contacting somebody to help you either through text chat or remote support or you can call them, request service, or choose to visit samsung . There's also a diagnostics button that I see on mine.

Hope that helps man. I remember how flipped out I was when it was happening to me. So glad it stopped.

Did your fast charging still work in that time?

For me it started when I plugged my phone into my tablet using a usb type c to usb type c cable

[Dstriing31]

No it didn't. Sometimes the phone wouldn't even charge at all.
