I have a Galaxy J7 (2015 version) cellphone that I purchased in 2017. I'm trying to replace the headset that came with my phone, the right speaker has very low volume and mind you, I've only been using them for 3 months. I went on the J & J website for Samsung parts, but they do not carry them for purchase. Is there another legitimate site where I can shop? When I look the headset up on Google there are a lot of knock-off Samsung products and I would rather buy the original Samsung headset.
