I bought my LG Shine 4 months ago, just last night I wanted to charge it because my battery sign kept blinking. So I charged it, but usually when it's charging the screen would appear a "Charging" picture. That didn't show on the screen, so I thought it was normal. When I had awoke nothing, not charge. So I grabbed my sister's charger (we have the same phone) and charged it. It charged but I didn't get to charge it fully, so I put it back to charge... now it doesn't charge it all! I even tested out with my sister's phone and now its the same problem! Is it the phone or the chargers?
