Why is my iPhone 5s acting weird?

So just recently my iPhone has been acting up. Every time I listen to music Siri will always pop up when I didn't do anything. It will always pause randomly. Then it will always skip to a new song or it'll skip really fast through the song. My phone is only four months old and it just started doing all of this and it's only when I listen to music other than it's fine?

Either send it in to apple or go to an apple store they will give you a whole new phone

Is this even happening when you're not using your Earpods?

Earpods tend to have this problem, where the remote on the earpod wire breaks and starts pulsing random commands to the phone.

If this problem occurs even without the earpods on, then it's a phone issue. Try restarting the phone by pressing and holding the lock key, swipe to shut down, wait a few seconds, then press the same button to turn the phone back on. If the problem still persists, contact apple for support.

If this problems doesn't occur without the earpods, then it's an earpod issue. You can get a replacement.
