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...

I have got the same problem with my Samsung phone A20e it says connected then disconnected and the screen keeps coming on this is happening when the power lead is not connected if I power down the phone then restart it stops doing it for a short while on some occasions the phone will not power up again even though the battery is fully charged I then can to connect the power lead with the phone still off then wait for the battery power level to display and then the phone will power up I feel that 8s is a software problem and would like to ask samsung too a software up date that I can download to solve the problem 

Please

I fixed mine by taking a pin cleaning the usb port (several times),then switch the phone off and back on again. Notification disappeared and can put phone back on standby again:) happy days. Just see how long the battery last now, as it was draining the battery. X

Had same problem tried all the fixes (settings etc) but none worked. Then read to turn phone/tablet off. Plug it in when it’s still off and when charging icon appears turn it back on still plugged in. This worked for me
