Resolved iPhone 6+ sound/speaker really bad noise

Over the last week my iPhone 6Plus is making some really bad noise. Has anyone else heard this before and what could be the cause? No fancy apps installed nor jailbroken the iPhone.

I have to reboot the iPhone 6 Plus to get it back to normal state. Directions appreciated!

Cheers
