Got the S4 on launch day and noticed both Google maps and Waze wouldn't always work. Sometimes they would and sometimes not. Then at some point, 14 days after I had the phone (past the return policy window), the GPS stopped working completely. I did a complete reset and got it to work for a short period of time but then it crapped out again. AT&T is sending me out a new phone. Well a "like new" phone. They said it's most likely new because the S4 is a recent handset. Has anyone else experienced any GPS chip issues? I can't keep doing a full reset on my phone because the GPS isn't working. I sure hope this "like new" phone doesn't have this problem.
