So last year I dropped my phone into some water and i checked and everything was fine except the speaker. When I turned up the volume it said I was using headphones even when I was not. It was an old phone so I assumed the speakers were worn out. I watched a ton of videos and tried all the tricks and none worked. I just powered it off and put it away thinking I would need to get a new phone. The next morning the speaker worked fine. It did cease to work eventually because it sat out in the hot summer sun for too long. I got a new one recently. It’s the same model. The same thing just happened and i’m hoping that the trick will work again because it worked so well last time.
