I want to get a Galaxy S5 but I want to hold off on rooting it for a little while so I can avoid having any problems with the warranty if something goes wrong since most defects will show up early on if they are present. I want to be able to use the wifi tethering on a trip for labor day weekend. What are the best options on this phone with the latest updates? I don't know what software version will be on it when I get it. I have used foxfi in the past before I rooted my current droid RAZR MAXX. A lot of these apps don't always work depending on phone, software version, and carrier.
