I bought my Galaxy S7 phone only 2 weeks ago. When i play videos in Facebook or Youtube , or even a video I recorded myself, the sound stops after about 2 seconds. I just chatted with Samsung who, as usual, seems like they don't know anything about this issue. I have found many posts on their community forums and on AndroidForums.com about this same issue. None of the suggestions posted in these forums by other users have solved the issue. I deleted several 3rd party apps at the suggestion of the Samsung rep and it didn't help. I really don't want to do a factory reset because I did that on my S5 right before buying the S7 to solve a different problem and proceeded to lose ALL my texts and a lot of my contacts.
Any ideas???
