Does my warranty cover this issue? Weird mic static issues at random times.

Mic bugging out randomly.

Multiple cases of this issue and i don't know why, i feel like maybe its snapchat?

It happens randomly its so embrassing when i get a call and all they hear is that. Or when i send a voice note, this phone cost me a bit over £1k.
