Recently bought a S3 its a SCH-I535 with 4.3 on it. What id really like is to just have the phone run more efficient and get rid of bloatware. i looked at the cyanogenmod installer.. does that work? also is there anyway to get 4.4 on it ? I dont know much about any of this stuff since my last phone was worked on by a friend after he went through it my galaxy nexus worked 100 times better than it before... Thanks !
