My Galaxy S10, when turned off, briefly displays a charging indicator that then disappears. When turned on, it shows no charging icon. The battery doesn't decrease, but it also doesn't increase when the charger is connected.
Yesterday there were "USB connected/disconnected" notifications on repeat, but no more today.
Hie. You might have a dirty charging port on your hands. Before waiting Anything, try cleaning the charging with something non metal, toothpick or broken match stick. Be gentle and try to reach all the corners of the port and see what happens from there.
