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 fixed this problem in A51 

Turn off the phone and by using thin needle clean the USB connector up and down side carefully 

Then start your phone again 

The problem will be eliminated

I'M DISAPPOINTED IN SAMSUNG.  I THINK THAT THIS IS A STRATEGY SO THAT EVERYONE CAN GO AND GET NEW PHONE.

SAMSUNG YOU LIE IF THIS IS WHAT YOU WANT.

MY PHONE SCREEN IS ALWAYS ON IT'S ANNOYING ME WITH USB CONNECTED AND DISCONNECTED.  SHAME TO THIS COMPANY.

My dads A17 has been having that problem and the gold picks were still gold and I stretched out the end of a q-tip so it would fit into the charging port and it worked

Same issue here with my A42.  Spent an hour on phone with tech support.  The only resolution would be for me to mail my phone in for repair. Repair takes 5-7 biz days not including shipping.  Cannot ship me a loaner phone and either will carrier. Only option is to send your phone in and be without it for 2 weeks? Awful  .  See you later samsung

Funny since I tried this already and then  tried everything else and was told by samsung to send in my phone for repair (without a loaner).  I just saw your post and decided to try and clean it with a needle. Did not believe it would work since it seemed so obvious. But it worked, at least for the last hour.  Hopefully it remains working.

bro, you have saved me, I have done what you say, clean the port and the problem has been solved. I was worried because my cell phone screen does not turn off due to the constant notification of the charger.
