Hi I'm new here so bear with me if these questions have been asked. I bought a vibrant and love it so far. But my battery life only last like max 7 hours if I listen to some music, text and use internet for a bit. My vibrant also sometimes lags and I already did the factory reset. Also my headphones sometimes disconnect from the jack even though they still plugged in. the music player sometimes the songs skip which doesn't happen on my computer or old phone. on the box it says the phone was shipped june 30 if it matters. I just need to know if I need a replacement because I'm still under the 14 day policy return. Thank you.
