Mobile service providers have an uncomfortably strong grip on the Android platform as a whole. For instance, all four U.S. versions of the Galaxy S6 and S6 Edge play their carrier's obnoxious jingle every time they boot up. You don't get any say in the matter—if you buy your phone from one of the big 4, you're a walking audible billboard.
So unless you own stock in T-Mobile, AT&T, Verizon, or Sprint, you're probably tired of hearing these played-out jingles. Fortunately, the process of removing the boot-up sound on your Galaxy S6 is incredibly easy so long as you're rooted, and I'll outline it all below.
For this one, all you'll need is a root-enabled file browser. I'll be using Root Explorer to demonstrate, but the process will be pretty much the same with any of the free options that you can find on the Google Play Store.
First, head to the root partition of your device. In layman's terms, this is the highest folder that you can get to in the folder tree. From here, open the "system" folder, then head to the "media" folder inside of it.
Next, open the "audio" folder, then head into the "ui" folder inside of it. At this point, make sure to mount this folder as "Read/Write" so that you can make changes to the files it contains.
With the folder mounted as "Read/Write," scroll down a bit and locate the PowerOn.ogg file. Long-press this file, then select "Rename."
From here, simply add a ".bak" to the end of the file name, then press "OK." At this point, you're all done—reboot your phone, and you'll notice that the annoying boot sound is gone.
