How to fix the sounds in phone when I'm using my earbuds?

Recently my Lenovo S820 ROW are having sound problems whenever I'm listening to music or watching a video on it while using my earbuds. Whenever i plug in my earbuds I can hear a buzzing noise and when I play my music the background music's bass gets really loud and the audio gets muffled and it's the same when I'm watching videos. This started when my earbuds got caught at a door knob when I was passing by, it got unplugged from my phone and since then it have been behaving like this whenever I plug in my earbuds. I tried other earbuds and headphones but it still behaves the same. How can I fix this?

Need explanation of various camera capture mode on android smartphone?

I just bought Lenovo A859 (with Android 4.2). I notice that the camera has several capture mode, like:
-Normal
-HDR
-Face Beauty
-Panorama
-M.A.V.
-Auto scene detect
-Smile shot
-Best shot
-EV bracket shot

I can only use several of them since they are pretty cut and clear use. But I don't know the rest like how are they different or how they are best utilized. I've been looking on internet for sometime but can't help a good answer. Can someone please help me?

Added (1). After several hours messing around with the camera, I think I get some of the modes, but still don't know the following:
-HDR: I need to hold the camera steady for several seconds but I don't notice any different from the pic taken.
-Auto Scene and Best shot: Just point and shoot, but again, I notice no difference from the pic taken.
-Face Beauty: from the name I presume it's for taking people pics and makes them more beautiful (w/o photoshop), haven't tried it on people though…
