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
-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!
I too had started to face the same problem with my a51 for two day.I tried everything in settings like cache clear of usbsetting app ,usb debbuging, usd type use setting etc but none solved my problem. As here is rainy season going on i doubted that may be thr could be some problm with usb ,it may have got moosture some how so i tried to clean it using thin needle slowly and very carefully .was just scracting the golden pins of usb type c port. (And yes dont forget to switch off ur phone while this). After cleaning ijust put some white cotton thread in it n again try to take out dust using the same needle.the thread got a lil bit of brownish.
And switched my phone ON. Bingo it worked like charm.Blv m i was so so worried as my traded were going on n i dont want it to send in service center
Hope it will help u guys.
Do thing carefully dont break usb port
Hey if anyone needs a help I kinda solved my problem. Had this isuue for months with battery drain that was crazy cleand port had original charger nothing worked till I lost my charger. When to buy a. New one and the only one available was the knew usb to usb tupc 25 watt charger. As soon as I started using that charger phone would sleep and battery would be back to normal . Still have the usb disconnected notification but phone will sleep and battery drain is back to normal and lay almost whole day
Also found old charger and tried using it again battery problem came back but when usiy new charger it went back to normal might be Samsung pulling some BS or isolated case idk but if this works for anyone else or already has let me know interested and wanted to help cause I know how this problem sucks
Hello, I'm experiencing a similar problem. My phone won't charge and when i plug the charger in it keeps saying "USB connector connected/disconnected" any idea of what i could do? I used a hair dryer as well and i tried cleaning the port, no luck whatsoever. I'm thinking of getting it repaired somewhere but I'm trying to find solutions at the moment.
