I started having this problem a while ago. I would plug the phone in and have to hold the charger in a certain position to get it to charge properly. I solved this problem twice by getting a new charger, but eventually these would experience the same problems. Then the phone started to not recognize the chargers at all unless in really wonky positions, and then it would occasionally start buzzing between charging and not charging. Now, even with a brand new charger it simply won't charge at all. How do I fix this without buying a new phone?
