Shower Stall Phone Holder/Speaker Amplifier

I like listening to podcasts and music in the shower. However, there's not a great spot to sit a phone around my shower. So, I needed a way to hang it on the shower door. But, I wanted it on the outside, not the inside. I've heard water and phones don't mix well. :-)

So this is my answer. In my case, I have a Samsung Galaxy S6 with a case, and the speaker is on the bottom. So, I can now start my music/podcast, place it in the holder (upside down) and get a decent amount of sound into the show
