Help with a Samsung Galaxy Centura speaker.

[cyberlox]

I got a Samsung Galaxy Centura a few months ago, shortly after the speaker broke when I was listening to Pandora. A couple months passed, I didn't mind seeing how I could just use the headphone jack, I hit it on something and the speaker started working again. But it died again shortly after. What is a good way just to fix the speaker entirely so I don't have to go out and get a new phone? I highly dread getting a new one because I have a Blizzard mobile authenticator on it. So any help will be highly appreciated, thank you. c:

There could be a hardware defect. How long have you had the device? Perhaps it's still under warranty for repair?

Ive had it for less than a year. And I got a two year warranty on it.

I had the same problem for the past day and a half. Pandora turned on by itself yesterday and I noticed I was not getting any sound out of my phone a little while after the incident.I could only get sound through headphones. I tried looking up solutions on the net but nothing was working.
Here is what I did...
I started to become suspicious that Pandora may have something to do with it since I have read about similar problems from others whose phone's sound quit while using Pandora. I finally went into Manage Apps > Pandora then Clear Cache. I then turned the phone off, took out the battery, put it back in then restarted the phone. I am not sure the reboot was necessary but My sound is now working properly. If you were listening to Pandora and your sound quits try clearing the cache.
