Same problem on my A70 . maybe i found a temporary solution . in my case i activate Developer mode ,search for
Default USB configuration and select "Charging only". after this the notification still there but at least the display turn off when you lock the phone . no chargin problem in my case.i also update to latest software available.
I have excatly the same problem I try everything but i cant fix it.The battery of phone is bad and almost the time is llagy.
I may be having the exact same problem.
When it is idle and locked with the screen off, the screen keeps turning on.
When I am using the phone, I keep getting an alert in the Notification bar from "Android System" with message "USB connector connected", followed by an alert from "Android System" with message "USB connector disconnected".
No device is plugged into the USB-C port.
Has anyone figured it out?
Any solution? Ive facing the same problem anyone can help? I have samsung galaxy a70 and there is no anything problem if i charge my phone except the spamming notification usb connector connected/disconnected my phone is still new i dont know why
