iPhone 6 Plus camera taking blurry photos/videos?

My iPhone 6 Plus camera is taking blurry picture/videos post the iOS 8.1 upgrade. Seems to be an underlying hardware fault exacerbated by the latest OS update. If you put your ear to the lens you can hear it vibrate wildly. Could be an issue with the OIS. I bought my phone in Canada while traveling and cannot send it in to Apple where I am (India). Thus am trying to figure out if this is a hardware issue (with the camera) that I can fix by swapping out the part myself.

Here is a preview of what the issue looks like -
