Hello everyone!! Okay so everything started 4 days ago when my phone started charging unproperly and it wasnt giving fast charge and when i plug it it gave approx. 8h to fully charge I thought it was from the UsB cable so i bought a new one and it wasnt the cable so i got it refunded… it was the port I had the port fixed and everything came back to normal but there’s one thing left : my phone is not fast charging with original cable and the original adapter and i want it to be back as it was before everthing happened :p Thank you for your cooperation I am very thankfull ❤

Try using a friend’s fast charger. The Samsung ones tend to fail over time per my experience.
