Just curious: Despite tons of software bugs when I first used my Galaxy S3 4 months ago, my phone has been working flawlessly until today. I was texting my ex-girlfriend and all of a sudden my phone turned off abruptly. I tried to turn it back on but it wouldn't work. I spent 20 minutes ripping the Otterbox off and removed the battery; after 1 minute, I put the battery back on. The phone now works. Why did this fix the problem? Is this a sign of future problems?
