Works on Galaxy Gio 2.3.4 Works fine on my (rooted) Galaxy Gio with Gingerbread (2.3.4). Many thanks Biturix! Note, however, that if you shut down using an app like Quick Boot, No Startup Sound won't work! You need to shut down through the normal Android shut-down process.
Samsung Galaxy S4 T-mobile Not only cancels the annoying t-movile startup tone, it also turns the long power off tone into a half second of loudness. Much less embarrassing. Perfect app for this phone
Not perfect It does make the startup sound go away by turning on mute before shutting down. It does not turn off mute after startup. Technically works, but only does half a job. Samsung S5.
Doesn't Work! This application doesn't work on Dany Genius Tab Q4 1 star is nothing but only to write a review for this app for the tablet I am using (mentioned above). I request the developers to fix this. Thanks!
Xtine This worked better on my Samsung S4 than Silent Boot did - caught most of the stupid T-Mobile sound before shutting down. It doesn't re-enable the audio on startup, however; that would be helpful.
Helpfully Works well on my Lenovo ideaTab A3000 (Jelly Bean 4.2.2). Thanks for the hardwork. :) *give u 5 stars
