TF: Fast Light

Quick flashlight. Shake, notification, voice.

Fast Light is a plugin for Tiny Flashlight and depends on it.

Fast Light gives you quick and convenient access to your flashlight via 3 different methods:

* Shake on Lock screen

* Voice commands on Lock screen

* Persistent notification

Shake on Lock screen:

================

* You must already have a screen lock before attempting to use this feature. If you don't have one, open Device Settings -> Security -> Screen lock and pick one.

* Face Unlock may be problematic, because the camera interferes with the flashlight function

* Enable Shake on Lock screen from Fast Light

* Press the power button to turn off your screen

* Press the power button again to show the lock screen - do NOT unlock the device

* Shake

Custom lock screen applications (downloaded from the market):

================

Custom lock screens do not behave like the standard ones. Right now Fast Light supports the following custom lock screen apps:

* GO Locker

* WidgetLocker

* MagicLocker

Timeout setting and accidental starting

================

Fast Light uses an advanced shake-detection algorithm, but there is always the possibility of false-positives. The most frequent case of accidental starting of the light happens while the device is in the user's pocket during a walk and the power button gets pressed. If a timeout value has not been set the battery will be drained very fast. The recommended Timeout value is 20 seconds.

Voice on Lock screen

================

* This feature is available on Android 2.2 and newer

* You must already have a screen lock before attempting to use this feature. If you don't have one, open Device Settings -> Security -> Screen lock and pick one.

* Face Unlock may be problematic, because the camera interferes with the flashlight function

* Read the info for custom lock screens and the Timeout setting in the Shake on Lock screen section above.

* Enable Voice on Lock screen from Fast Light

* Press the power button to turn off your screen

* Press the power button again to show the lock screen - do NOT unlock the device

* You can say one of the following commands in English

- "light"

- "lights"

- "torch"

* Additional languages will be added soon.

If you are on Android 4.0 or earlier:

================

Voice recognition requires an active internet connection. You can change the language from:

Device Settings -> Voice input & output -> Voice recognizer settings

If you are on Android 4.1 and newer:

================

You can install a language pack for most popular languages, so the voice recognition will not require an active internet connection.

To change the language:

Device Settings -> Language & input -> Language

To install a language pack:

Device Settings -> Language & input -> scroll down -> Voice Search -> Offline speech recognition

Persistent notification:

================

The persistent notification allows you to toggle the light from anywhere as long as the notification bar is accessible. There is an additional option, which shows the battery usage and remaining time while the light is on (only on devices, which has a camera flash). Before using the battery usage feature, you must calibrate it. Here's how:

The light should be kept on for 5-10 minutes for maximum accuracy. Make sure the device is NOT charging. After the first data appears, you must NOT turn it off. The longer you keep the light ON, the better accuracy. This has to be done only once.

Read Phone State permission:

================

This permission is used to stop the light, when the device starts ringing or prevent the light from starting while in a call.
