I got my s3 back in october through verizon. The past week or so the hold/power button is now loose? and without clicking the button and by simply brushing it , it will lock or ask to restart etc etc. I can still use the phone, I just cant have my finger/hand on the button...

Do I send it in or is this an easy or common fix?

I've been messing with mine a bunch and doing a lot of reading about it lately and haven't heard of anyone with that issue. Might want to send it in if it's bothering you

Your options are either getting it fixed, or
