So I guess at some point today I must have hit the rear speaker on my phone while it was in my pocket cause the sounds are all muffled like its under water and slowed down. Theres a small dent on the gold mesh on the speaker so I know I hit it on something. Is there a way to replace it myself or do I have to bring it in for a whole new phone? I don't wanna loose root by getting a new phone or anything. Any help please.
