I have a black Samsung SPH-a640 through Qwest. It has been working fine for the near year that I have had it, then it started to act up. It wouldn't turn on, and when it did turn on, it only did for a short period of time.
I noticed that if I pressed down hard on the charger slot, that it will stay on continuously until I depress the slot. I have a feeling that it has something to do with the internal circuits, but they all look fine.
I can put up pictures if needed.
Thank you!
