Music player issues with iphone 6 plus
I've been having trouble with my music player on my iphone 6 plus.
It's a fairly recent purchase and I'm looking for solutions. Sometimes when I pull up apps on my iphone the music that I downloaded/transfered to my phone skips. By that I mean it sounds like a cd track skipping/stuttering when you walk over a bump. I thought it was an iphone problem but when I got it changed out the problem still continued.
I'm on my second iPhone so I know that it's not a hardware issue but a software issue. In fact the music only "stutters/skips" when I pull up another app while playing music.
Is there anything I can do? i did all the steps. Restored my phone and what not and even switched it out for a second iphone. If you guys can help me out that would be greatly appreciated.
iPhone 6 Plus, iOS 8.0.2
