What does updating the profile do for a phone? Specifically: Settings->About the Phone->System Updates->Update Profile I'm on a Samsung Galaxy SII Epic (Sprint) if that makes a diff I'm asking bc I have been experiencing a number of phone issues over the last few days, 50% faster battery drain, txt messages and voice mail msgs not downloading to my phone till after reboot and such. I finally called tech support after I started receiving text message from random numbers not in my address book that seemed to be intended for other ppl. Supports answer was update your profile that will fix everything... When I asked them what it did, they gave me some BS answer about it updating the 5 software builds of my phone, but they couldn't explain what that meant. So I've done what they asked, have no idea if it will help, or even what it does, other than I'm pretty sure it doesn't do what they told me it does.
