Side-button issues (iPhone 6)

Hi everyone,

since a week or so, my iPhone 6 is acting weird with its volume buttons/lock button. The volume will sometimes randomly go down all the way to mute and the volume display will not go away. Then when you try to increase the volume, it will instantly go down and i have to reboot my phone to make it stop. Furthermore, the buttons will work one day but then malfunction the other day. Within the week this started occurring, nothing special has happened to the phone, it hasn't fallen, no water involved, no sand or anything.

Is this something hardware related or software related? I haven't yet resetted the phone (except for the settings, which didn't help). One sidenote: the phone is slightly bent on the side of the lock button (Pic: http://m.imgur.com/Uygyz4a), but has been for quite sometime an has never caused any problem and has not worsened over time.

What do you guys suggest to do?

Thanks in advance.

 

The buttons are fine, they click fine, no problems with them.

It started a week ago, my volume-down button stopped working and soon after that it started turning the volume down on its own. Like i said though, the button will sometimes start working again though.. It's really strange.

 

I guess i have to try that then, let's hope it'll do any good. Are there ways that a phone can get infected with software through the WiFi hotspot option?

 

Thanks for your reply, that'd be great thank you! It would make some sense if it has to do something with the headphone jack because it happens more often with my headphone plugged in. However it does occur sometimes without anything plugged in too..
