[SOLVED]Add functionality to fingerprint sensor - Samsung Galaxy A8 (2018) Questions & Answers

Hello,
We already can use the fingerprint sensor to open and close the notification panel and I would know if it is possible to use it for others utilities like for example touch the sensor to come Bach to the home screen.

Yes, we can. But we need an app like fingerprint gestures to do it. It's better with root.

Can some tell me if there is an option on mate9 to lock each apps apart from general fingerprint lock on the phone.
If not , which app would be the best?

Yes, very easy to do. Same as the video below but instead of entering a lock code, it will use your finger print on Mate 9.

Double tap to wake

have this feature for honor 8?
How?
maybe root needed?
Not truly possible. There are apps (that don't need root) but you end up A) killing your battery life and B) losing or at least decreasing the functionality of unlocking other ways like with the fingerprint scanner.
You can try this and see if it works lol
https://forum.xda-developers.com/mate-8/general/enable-double-tap-to-wake-t3312676
Just a bit off topic: What do you think causes the 10 buck flip-case that Honor sells to cause the phone to wake and sleep? Is it magnetic, or just using some sensor it uncovers? I got one with the phone and it works great, and there appears to not be anything magnetic inside it, or even a piece of ferric metal.
Anyway: Whatever it is that allows that must be very low power because there is next to no drain (especially on the b360 OS I installed today) when it's closed. Nothing appears to be setting around sucking up power awaiting the incredible event of the cheapo case opening or closing. There is a setting for it in the settings, but I've no idea what the settings changes. Actually I suspect that link in @Saythis post could work.
you can try some xposed modules but the battery will drain faster
Not possible for now, the honor 8 kernel doesn't support it
You can try to follow instructions from this thread: https://forum.xda-developers.com/hu...ide-how-to-enable-double-tap-to-wake-t3426809 . This is for Huawei P9 Lite, but the script of Kernel, i think is the same. The only inconvenience is you must root your phone.

As always on XDA and with any modification, ROM, Kernel, etc. the risk is up to the user. I tried it and couldn't get it to work so I suppose the Honor 8 has a missing module/driver for it in its kernel.

It should not work if the kernel isn't identical on both devices

EMUI supports it regardless of the kernel. The kernel doesn't need to be identical on both devices, it simply needs to have the module/driver to keep the screen capacitive when the pixels are off for DT2W. The display also has to be able to remain capacitive while the pixels are off. So no, the kernels don't need to be identical. There's a hardware requirement as much as there's a software (kernel support and OS support) requirement.
The Honor 8 doesn't support the use of double tap to wake, you could just use the fingerprint scanner on the back to wake it. Which is super fast!

Depends on your perspective. I'd like the tap to wake function if I had my handset on the desk while I was working rather than have to pick it up to check for messages, emails or miss calls.
Do you guys not have the "wake on notifications" setting ? That wakes it for any notification (or it does as I've got it set on b360 right now, but it worked on b320 as well).
Also, I mentioned before that the 10 buck flip case turns on the screen and I can't even find a piece of magnetic metal in that cheap case, so it might be using some sensor and there is a setting for it also in the settings. (case-on == on). Gotta be a way between these things.
I was wrong about the magnet: I found it using a paper clip and it is the lower half of the screen-facing area on the honor8. It's a "slight" magnetism and apparently the settings switch enables it's detection. I was hoping it was using a different type of sensor that we could spoof.

Try "Glance Plus" from Google Play. I use it on my H8 and it works just the way I want.
Wave hand over proximity sensor to check for messages, missed calls, date, time and battery status, it's configurable. To wake up your phone, double tap on screen.
Can't give you a link, I'm a new user, but find it at Google Play!
The glance is a better Idea for me

I will definately look into that! Sounds like a great way to check the notifications without having to use the fingerprint scanner.

Yellow hue on lockscreen

Hello everyone
I just found out that there is a yellow hue when you're on lockscreen. I've not seen that earlier. Could someone tell me what is going on? Please check the vid:
https://youtu.be/c5vC1CuH__E
Thanks
It's a normal screen overlay when you invoke fingerprint sensor. I don't think there's a system-side way of disabling it.

[No root] Finally, an app to enable native Lift To Wake (lockscreen)

TL, DR. Where is the download?
github.com/xubowenhaoren/OPLiftToWake/releases
What does it do?
This is a simple app to enable Lift To Wake for OnePlus 7 series.
It is not the Lift To "Ambient Display" in the stock Settings App; it enables the true Lift To "Lock Screen" like other phones.
Why do I want this feature?
You've probably already known that OnePlus, in Android 10, reveals the notification content on the lock screen after Face Unlock.
But to see those notifications, you either need to:
1. Pick up the phone and unlock with your finger at the Ambient Display. A two-step process.
2. Pick up the phone and press the power button. Again, a two-step process.
Now with the app, you can pick up the phone and the lock screen immediately shows up.
How does it do this?
It listens to the native system sensor (`oneplus.sensor.pickup`). In my testing, it is very power efficient.
What phones does it support?
I have tested this on a OnePlus 7T with Android 10. It should also work with other OnePlus 7 series.
Note that for earlier OnePlus phones, there is also a [pickup sensor] but with a different name.
If you want this app to work with earlier OnePlus phones, you should try replacing this line in `Utils.java` with the correct sensor name:
```
mSensor = Utils.getSensor(context, mSensorManager, "oneplus.sensor.pickup");
```
How do I use it?
You probably want to turn off the Ambient Display first.
After installing the app, turn on the "Lift To Wake" toggle.
You should also consider turning off the battery optimization of the app for a more consistent background performance.
Do I need Magisk for this?
No, it is root-free.
Credits
Much of the code is from the Lineage OS team.
Other code references can be found in the code comments.
Love this feature thank you!
Works like a charm ? thanks.
Awesome! will give it try, hope there is no battery drain.
Great to see! Cheers
It is still a 2 step procedure when i use face unlock along with fingerprint.
It should be a command that when I pick up the phone -> auto open lockscreen -> auto trigger face unlock.
When i want to use fingerprint, just tap to wake ambient display and unlock with fingerprint.
I really dont want to sacrifice FOD to use only face unlock.

This is the app for you then. Also, you don't lose FOD at the lock screen.

You dont get my point, bro. When you use both FOD and face unlock, this app just show the lockscreen when pick up. Then u have to choose putting your finger on FOD or pressing the face icon button on top of the clock to unlock.
My desire is that the app will trigger the face unlock automatically in that situation.

I am using a OnePlus 7T. In my case, when the lock screen lights up, Face Unlock automatically works and my new messages reveal their content.

Weird!!! Something prevents the app from triggering face unlock automatically. Maybe because of the pop up camera firmware in 7 pro.

My OP7T doesn't even have a pocket mode, so I can't test that for you. However, the original Lineage OS code had support for pocket mode. You could try to add it! :good:
It's cool. Kinda slow thought.
If I turn off the notification, will it keep running?
And thanks for it, really useful:good:

Yes, I've tested this.
Facing a minor problem. The app has to be opened up to function after deep sleep i:e in the morning. The battery optimization is off for the app.
Any ideas how to fix the issue.
Nice I love it. Great job sir. ?

How is tha gonna stop accidental fingerprint detection and vibration??
The solution is to deactivate the fingerprint sensor ?
More seriously, there is no false detection, the sensor is doing its job, as soon as it feels a finger it tries to visualize the fingerprint, I do not see what is boring, If it wasn't so sharp it would be a nightmare to unlock the device !

No, you're wrong. It could be set to only vibrate when it detects a correct fingerprint. Which would be much more logical in my opinion. Or give the option to only activate the fingerprint sensor after power button is pressed.

the vibration is not there to validate the unlocking, something that we see anyway when the home screen opens, but to say that the analysis of the finger starts and that we are at the right place..
The last option might be fine for you, but personally it's a waste of time having to press a key before I can scan my finger, not sure Poco implements this In a future update ! ?

These options should be there for those who want them, they're easy to implement. Options are good I too find it annoying reaching into my pocket and having the phone light up and vibrate unintentionally.
Yeah noticed that also here where it rarely happend with my k20. It's just the new fingerprint placement.

Yes indeed having more options is positive, I'm just saying that I don't think they will, as it's a pretty special option that very few require.
Normally if you are looking for the device in the pocket, it should not turn on or vibrate because it is deactivated by the proximity sensor, in any case mine remains as dead if I hide the part upper screen..
I hope for you that a function will emerge
For me, it is clear that the "old" hardware fingerprint sensor is much better than the modern software sensor that's imposed on new devices.
But we cannot change this, so yes : some options for lock screen vibration activation-deactivation are welcome. Me too don't like to feel the phone vibration every time I touch accidentally the screen trying to extract something of my pocket, including the phone.

You can disable 'haptic feedback' in the settings, it will disable the fingerprint sensor's vibration too.

Yes, only for interactions like button press, gestures,etc.
