I own an A71 Samsung that came with Fast Charger Wall Plug (USB C to USB C).
I also own a S8+ from few years ago.
A71 with Samsung Fast Charger when it's plug. It connect (charging) then drops (not charging)
S8+ with Samsung Fast Charger when it's plus it Charges fine and never gets dropped.
I have tried to charge my phone with the USB to USB C wire charger.
A71 with USB charger (USB to USB C) Charges Fine without any issues.
What is the issue?
USB Port of the phone needs cleaning? USB Port of the phone is damaged?
USB C to USB C wire that came with fast charging needs to replaced?
