Putting a phone in silent mode isn’t difficult, and doesn’t take long. That doesn’t mean that it cannot be done faster and that certainly doesn’t mean we’d all like to be able to do it faster—especially in those instances where we forget and the phone starts to ring.
This is something that XDA Forum Member Luminger is currently working on with an Android application called Flip4Silence. The application is still in beta testing, so there’s a few issues but otherwise it’s a pretty versatile application for what it was created to do. The features include:
Silence nearly every notification!
Is planned to be a full replacement for every ringtone picker (please tell me what you want from your ringtone picker)
It’s nice to your battery as it’s only active when something happens and not all the time.
More control over the sensitivity used (no more “low”, “high”, “normal”, you are in charge now!).
MP3 ringtones are now supported! The UI is not really finished, it’s at least planned to add the album covers to the list.
So besides silencing notifications, it also gives you some versatility when it comes to things like sensitivity and Luminger is taking suggestions for features on future releases. As stated, though, it is still in beta so expect some bugs around the system. There are also a few things that just won’t work right, including:
You can’t use it to put silenced ringtones into the default settings. Please never ever put a silenced ringtone into your phone ringer or the default notification sound. It will just not work (and will never), trust me. However, you can put in a “unsilenced” ringtone (more later).
Currently the sensors will report strange results if you have vibration on while a ringtone is played. It lacks a good filtering, so it’s not really usable currently.
However, with updates regularly coming, users can expect bug fixes and new features as new versions are released. Additional information, download links, a nifty FAQ, and screen shots are available in the original thread._________
