Hey guys, im having issues when sometimes the speaker just shuts off even though something is playing and I have to turn down the volume or close everything and start it up again for it to sound again, im scared this is a defective speaket issue or if water was the cause of it, ive washed my phone twice with water cause of ketchup incidents but its never been submerged in water, ive heard the phone has like sticker that turns red to trigger warranty against water is this true? What should I do? Because I can probably get it replaced by tmobile but im scared they will say its waters fault and make me pay for device? Suggestions?
