Can I send an automated SMS to any specific number by an application/service (which I set ON), if phone gets switched off before closing that service or application? Also can I do the same if phone breaks down in an accident or if I do specific action on phone, such as "Tap the screen 3 times while phone's screen is locked", or "shake the phone 3 times while it is locked"?

Tasker should do the first things you asked about, but I doubt you'll find anything that can recognize "Tap the screen 3 times while phone's screen is locked" or "shake the phone 3 times while it is locked", short of writing a custom app.


Tasker is a great app in general that you really should check out since it sounds like you want to do a lot of automation type stuff.

  • While agreeing on the "tap while locked" (especially when the screen is off), Tasker should be able to handle the "shake" stuff fine (except if the device turns the sensors off when screen is shut off). Difficulty here, however, might be the special shake-pattern (which Tasker AFAIK does not support itself); maybe some addon is available which could realize even that. Btw: Free trial of Tasker avaialable on their homepage. It's worth every cent to buy it, when you find you can deal with it. You just have to get used to it ;)
