My Samsung a50 charger has been working perfectly fine since I bought it last year but then when I was charging this morning I suddenly got a notification that my USB device isn't supported. I tried to use my brother's fast charging cord to test but my phone's not charging there. I tried again in a regular charging cord (not fast charging) and then it suddenly worked. I've been restarting my phone for like 6 times already but it is not working. The notification that the USB device isn't supported is still appearing in my notif even though there isn't any usb plugged. What to do?
