my iPhone 6 is having issues. it is always offloading apps even if i just used the app. if does not always let me play music or pod cast it says it is playing but I here no sound and it is having trouble syncing with my car through Bluetooth the connection keep failing or it disconnect just as soon as it connects. I was wondering if there was a way to ether fix it or maybe I could exchange it for a new one of the same model at no charge or do I need to just get a new phone. Just wondering because money is tight.
