Hey, good evening. I have a samsung j2 prime that used to function well when connected to a laptop. All of a sudden it stopped working. Ive tried different cables and laptops but it still wont work. Usb tethering is grayed out. Ive tried everything but it still wont work. Just charge. Its rlly important for me because im in college and its my main tool and now its messed up. I could rlly use some help. Thank you in advance.
