Silent Boot is a simple app that uses a workaround to suppress annoying startup sounds on some Android phones. It mutes the phone on shutdown and restores the previous state after boot which prevents any chimes to be played.


The project has an interesting history, as it originally started off way back in 2010 after a discussion on the forums. This means it was still created with the Android Development Tools for the Eclipse IDE with an initial API target level of 3 - that’s good old Android 1.5 Cupcake!

The first releases are old enough to break Google Play:

Over the years I gradually improved and modernized the codebase without ever doing a full rewrite, which makes the Git history an interesting read.
