This application can not collect, store or publish any user information.
This application can not use any data connection, detect your location or access your contacts. It also can not read any sensitive information stored on your device. This guarantees maximum security for your data and your privacy.
This application does not need any special permissions except for the one to bind the Android notification listener service.
This is the only authorization required to properly interact with your incoming notifications (you will be asked about it explicitly when it is run for the first time).
Devices with Camera Hardware level: LIMITED (partial Camera2 API support)
On some devices the manufacturer implemented only partially the Android Camera2 API; this means limited hardware access to the camera for the developers. In this case the only way to let this application properly take control of the front flash is to use the old Android API and that's why you may also have to authorize the application to use the hardware camera.
With the first run and only if the application detects this limitation, as per the above case you will be asked explicitly to grant full camera access permission (even if the application should only use the front flash, the flash is strictly part of the hardware camera).
You must agree with providing access to your device camera, file system and audio recording for the application to function. This access is limited to user only. None of the data present in your device can be shared with me or any other person.
Keep in mind that if you deny any of these permissions the application will not work!
If you know how Android works and the meaning of application permissions, you can easily verify by yourself all the above statements.
So please, avoid claiming that we are a bunch of criminals here just to steal your data with this application... in doing that, you would be such an IDIOT!
Lately several devices (mainly, but not only, running Android 8.x) are equipped with front flash with custom hardware that developers can not have access to. Furthermore, with the introduction of the new firmware based on Android 8.x, Samsung has inexplicably inhibited the use of front flash to developers on a wide range of devices.
Strangely enough, the front camera of your device may not be equipped with a "real" front flash for this application. When it "asks" through the Android API to your front camera some information about its front flash, the answer may be "no front flash available". There is no workaround this!
This is a software/hardware limitation imposed by the manufacturer (don't ask me why) and at the moment unfortunately there's nothing I can do. I understand your amazement, but if you experience this kind of issue at 99% of the time that's the reason why this application may not work and could report the non-availability of a front flash despite your eyes seeing a front flash.
Mainly only the branded (stock) camera application can handle this kind of front flash, using owned and reserved API.
Try it by yourself to install (from the app Store) an alternative camera application. Then shoot a front selfie and check if the front flash can turn on... or use any other application you expect to use the front flash (usually Instagram and Snapchat fail as well) and then let me know the results.
In addition, you can also try to install Device Info HW and then select the "Camera" tab and check all detailed information about the front camera of your device.
Finally, let me remind you that this app can't take control over the brightness, the color and the speed (On-Off phase) of a flash; unfortunately it isn't a LED... no way for the developers to handle these features.
All of them are strictly related to the hardware and its manufacturer and therefore vary from model to model.
As you can imagine, this application must be able to take control of the front flash of your device to work properly. In an Android phone this can only happen in one way: through the front camera as the flash is strictly connected to it.
The developers in fact through dedicated instructions, can turn it on and off at will. But it always has a connection to the camera and not directly to the flash itself.
To handle all the incoming notifications, an Android service will run in background on your device.
These are the main functioning at the root of this application.
Common issues & Troubleshooting
If you installed any startup manager application (such as Startup Manager, Autorun Manager, AutoStart Manager, Advanced Task Manager, BootManager, etc) or any battery manager/optimizer application (such as Greenify, Doze, Brevent, Hibernator, App Freezer, etc) pay attention to avoid killing the running "Flash notification service" otherwise this application will not work!
I also want to draw your attention to the importance of the Android wakelocks in the lifecycle of this application (if you don't know what wakelocks are, disregard the sentance below).
If your device is running an application that detects and blocks wakelocks (such as Wakelock Detector, WakeBlock, No Wakelock, Wake Lock - PowerManager, etc), keep in mind that the main features of this application will not work as you expect. So add it to the white list if any, or if you are interested in using this application in any way avoid blocking the wakelocks.
In other words, because of unreasonable battery optimizations implemented by some brands but not only, you have to be careful not to put this application in hibernation without realizing it or maybe killing or blocking the background service without noticing it. These are the most common causes of the main problems you may experience!
Please verify the impact over this application by any system tools / Magisk - Xposed modules which you heavily rely on (especially if your device is ROOTED).
So, double check your system settings before reporting any issues, thanks.
It isn't strictly related to the application itself. What drains the battery is the flash not the background service in charge of managing your incoming notifications, I can't do more in terms of optimization.
Battery consumption mainly depends on how long you will let the flashing loop run before you dismiss it (the shorter it is the better for your battery) and also on how many notifications you receive a day.
