followed the instructions exactly as stated. apparently the foam piece that covers the ear speaker didn't seal well because some of the liquid went underneath the foam and went in my speaker. now it sounds like crap. also the adhesive on the top part of the foam separated leaving residue that will need to be removed very slowly and painstakingly. Normally i wouldn't leave a review this negative but this has ruined my 1100 dollar phone as far as I'm concerned. STRONGLY DO NOT RECOMMEND.
