Anyone else having these issues with ipad

Hi I have an ipad air which I now own for a month and recently safari keeps crashing almost all the time.

I've also starting to notice this second click noise on my home button on my ipad air

For example I put my finger on the button and I can hear a noise as if I'm pushing it but I'm not

I don't know if it's become loose or something is wrong with it ?

I hope that made sense

Can anyone help me out here?

Btw I barley use the home button I mostly use the ipad gestures to get in and out of an app but when I do use it it's kinda annoying .... Is it an issue with my ipad?

I can't go to an apple store it's to far
