I am giving it 3 stars, for now. I am just now able to give it a try, after having it for a while. I do not know if it has improved the speaker volume of my phone for music, videos, and other media with audio. I have not yet made or received a call, in order to determine if there is any improvement in call volume on my end or one the other person's end. Before installing and using the app, even after adjusting all volumes to the highest levels, in call volume was so low, it made calls impossible

Sorry! It doesn't have any type of settings to check it out. And you definitely can not guarantee or give permission to really check out to make sure that it really works. To many Spam scams on things like this because they don't have any permission usages to be an Ear phone speaker volume. Not compatible with any type of phone devices. because it doesn't say this as well.

I'm very disappointed. It doesn't work when using the 3.5 audio/mic jack. When I first opened the app, I was not prompted to allow permissions so I manually went into my phone's settings and allowed permission to the phone and the advanced setting under this. It still didn't boost the call volume. I played around with every option. The boost slider was on. I even restarted my phone, still didn't work. Uninstalled.
