HELP ! USB connected/disconnected notification and lock screen won't turn off

[julianaalves23]

My Galaxy A32 keeps getting USB connected and USB disconnected notifications non stop when it's not connected to anything.

Because these notifications turn on the lockscreen by default, everytime I turn the display off, it turns back on right away, and stays like this. The only time it's off it's when the phone is chaging.

Besides this being obviously annoying, it's making my battery drain fast (because the screen is always on).

I saw the suggestions for this issue, this is what I've tried so far:

- Cleaning the USB port with a toothpick 

- Cleaning USB Settings cache and data

- Cleaning Android System cache

- Enabling Developer Mode, enabling USB debugging and setting USB default configuration to "charging only"

- Changing USB Settings with *#0808# to the last option 

- Plugging in and out an actual USB multiple times

- Changing to an original charger

And resetting my phone after every option. Nothing worked. 

How do I fix this?

I also tried to find a way to disable this "turning on display" when usb connects, just to temporarily fix that "screen on" issue. If anyone knows an app that does this, I'll be glad! 

Thank you

Esta é a Comunidade Portuguesa de Portugal pelo que podes falar em Português. Face ao já realizado, tenta verificar se ocorre em modo seguro https://www.samsung.com/pt/support/mobile-devices/como-ativar-ou-desativar-o-modo-seguro/

Se ainda assim continuar, deverás levar o equipamento a um Centro de Assistência Autorizado para que possa ser analisado.
