i've been using my GS4 for almost 3mos. it was only yesterday when i experience some issues. my phone does not charge. it don't even recognize the charger. i also tried to connect it on my pc. nothing happens. when i switched it off and plugged the charger, it just keeps on vibrating every 5secs. i will bring it on the service center today for checking up. but i was really bothered if it might be fixed. this issue is really stressing me out. hope you can help me out. i would really appreciate it.
