Hello, about 6 months ago I bought a Samsung Galaxy Centura from one of the local Wal-Marts. It worked great with minor exceptions such as, turning off without manually turning it off, showing itself to be charging while not on the charger, and not showing it was charging while on the charger, for the first two months, then it would not charge anymore even after taking the battery out. It happens my family's cell phones all can work on the same charger so therefore, I tried plugging the charger used for my Centura into my mom's cell and it charged, I then tried plugging one of their chargers into my cell, however it still didn't charge. Afterwards, my mom took the cell back to Wal-Mart and they confirmed, quote, "We don't know why it's not charging." Therefore we acquired a new Centura. which after 2 more months charger had stopped working, and 2 months more after that did the same as the first (same minor defects happened on this Centura). Now I'm asking on here what should I do (Note: Times are estimated, however I assure that I purchased the first Centura no more than 6 and a half months ago.) Please reply with an answer to my problem. Thank you.
