I wrote a little app for myself which turns the fingerprint sensor on Galaxy S7 Edge into a capacitive Home button - so you don't need to press the button physically, just touch it like a sensoric button. There are already similar apps on the Play Store, however none of them have an option to quickly enable/disable the service via Quick Settings custom tile (Android 7+ feature). It's a useful feature, because if you need to authenticate with your fingerprint in any app, it's needed to disable the service temporary.

App service runs in foreground thus there is a persistent notification placed in the notification bar. You can quickly pause/disable the service from this notification, or better use the Quick Settings custom tile. If you don't like the persistent notification, just hold you finger on the notification - notification setting will be opened and you can disable it (notification will be hidden but app still works fine).

Android 7+ is required, I'm using the app for several days already and there were no issues and no battery impact. I recommend to exclude the app from battery saving options to prevent it being killed by the system.

This app rely on Samsung SDK so it will probably work only on official or modified official firmware.

Don't forget to register at least one fingeprint in system settings, otherwise the app may not work.

Source code is available here: https://sourceforge.net/p/fingertouc...i/master/tree/

UPDATED on 2017-05-18:
New version v1.2.5:
- fixed crash when Fingertouch service is killed by system

v1.2.4:
- added check if at least one fingerprint is registered in the device
- notification bar is now closed on home button touch
- main screen is now scrollable (in case you use large system font)

v1.2.3:
- added option to start on boot
- added option to change the touch delay (useful if you use Samsung 'double tap' camera feature)


Get it for free on PLAY STORE

There is also PRO version if you wish to donate, it includes app whitelist and long touch function. PRO version has ability to disable itself automatically (for 4 seconds) when fingerprint authorization is requested in other apps. So you don't even need to use whitelist and you have 4 seconds to authorize with your fingerprint in any app after the request is made.

Uninstall the previous version 1.2.2 before installing 1.2.3!

Thank you very much for this, working as described. I'm planning on using this for a day and reporting on battery use, what has been your experience? Also, for anyone wondering, this does not affect the lockscreen fingerprint to unlock. Double tapping to open the camera does not work though. Great app to extend the life of the home button.

Edit: no noticeable difference in battery after several days use. Thank you for your great work

Wow, works, thank you!! @ranwej,
Can't you add a function that in case of longer touch will trigger a scanner instead ? I mean automatically. This could be function for donators )



Btw double tap on home must work for camera This would be show stopper for me

Yes it sometimes vibrates on very short/light touch, unfortunately it's Samsung SDK thing and I can't do anything about it. I don't like it as well

Regarding the question about battery, I haven't seen this app in Android battery usage list, so I would say it has neglible efect. But I have very good SOT overall (8+ hours).

I don't plan to add other features as I don't need/use them, including double tap camera. I would recommend you to try other similar apps on Play Store which have additional features, for example "easyHome" or "HomeTouch".

That's a really pity then... I like the concept, I would even donate for it.

The HomeTouch you have proposed seems to work with Doubletouch even with lite version still some additional functionality I have proposed would add additional value to your app, on top of current one like Quick panel and nice and clean design. Anyway, probably that is not your goal so thank you for sharing anyway.

Really love the lightweight apk. Double tap camera would be the icing on the cake but i can live without kit. Good work!
