Touch UI @ fingerprint sensor - Xperia Z5 Compact Q&A, Help & Troubleshooting

There is lots of apps now that support login via fingerprint sensor, but none of them works on z5C
Any chance it start to work on Marshmallow ??
it is great feature, i want to use it

Since Marshmallow will come with Google api that support fingerprint sensor we can presume that it will work on 6.0

Fingerprint sensor support

My understanding is that prior to Android 6.0 Marshmallow, OEMs had to add custom code to support a fingerprint sensor. I'm assuming that LG's support code would be different/incompatible with Samsung.
So, I think until the V10 gets updated to Marshmallow, the fingerprint sensor will only be usable to unlock the device, and to lock content in LG Gallery and LG QuickMemo+.
Does anyone know any different?

I set it up for the PayPal app without any issues. Haven't tried with anything else yet.

Interesting. LastPass shows the fingerprint unlock as unsupported, so I assumed that would hold true for all third party apps.
LastPass got back to me... apparently LG does not currently have a public SDK for their custom fingerprint support, hence why LastPass does not support it. Either LG needs to make their SDK public, or we wait for Marshmallow.
I guess LG must have reached out to PayPal and given them access to the SDK, in order for their app to support it.

Marshmallow Fingerprint API on Le Max 2?

Does anyone here know whether Le Max 2 and Le 2 have implemented the Marshmallow Fingerprint API for their Fingerprint sensors?
I think they did since all fingerprint apps are working (1Password, Google pay, app lock, etc.)

Fingerprint sensor access for App

Hello! I would like to know a thing or two about about android's fingerprint sensors. Apparently I am planning to create a mobile finger print scanner and it seems that hardware wise an android phone with fingerprint scanner has everything I need. Heads-up I'm a newbie in android dev and currently do not have any app developed.
I have done some reaseach and it seems that Android M has already APIs for fingerprint. But the articles I have seen only talks about authenticating the phone's user. Nothing about using it for different purpose.
So here are my questions:
1. Can I use and access the fingerprint sensor of android phones to scan fingerprint of different users?
2. Would I be able to develop in an unrooted Galaxy S6 Edge?
3. Are the implemetation of the sensors the same for every device?
Hoping for replies..

Can't you use faceID for banking authentication?

I was under the impression that on Android pie Google would allow all biometrics as options to login to apps instead of fingerprint only.
Is anyone successful with this?
I'm guessing no as face recognition isn't very secure.
Having said that I use the fingerprint sensor.

This is not the standard face recognition that most android phones use. This is with a dot projector and infrared light like the iPhone X models
I think it requires 3rd party developers to implement. Can't really see this happening as only a few phones have the 3d face scanning built in. I mean I think even Huawei doesn't have any apps that uses this technology i.e vault or secure notes.

I haven't tried my banking app yet but google pay uses it.
It is also just as secure as fingerprint and as secure as iphone.

It was just my understanding that Google implemented it for Pie the same way as for iOS. The apps for ios is just coded for biometric. No need to specify if it should be faceID or an older touchid phone.
So the apps should just ask for biometric authentication and therefor it should use whatever I has active.
The app developer would need to code it for FaceID, both my banking apps have settings within the app to use fingerprint login, there would be a setting required to provide faceID login likewise. The same also applies to my phone carriers usage meter, they have only just modified it for fingerprint login.

There is currently no Android standard for face unlock so using it as an identification for banking apps or making payments would be very insecure. Different Android phones currently use different methods to implement face unlock and some of those methods can be bypassed with a photograph.

Question Xperia 1 III ToF not supported by ARCore and alternative for 3D scanning?

Hello together,
does anyone know why the ToF sensor on the 1 III isnt supported by the ARCore Depth API (see [1]) and if there will be a fix in the near future?
Are there any 3D scanner apps that can utilize the ToF sensor without relying on ARCore or is there an alternative ROM with ToF support?
Best regards,
some XDA greenhorn

Your github link already has the answer. It isn't supported because Sony did not implement the Depth API to use their TOF sensor. Simple as they didn't do it. This is the drawback of an "open" operating system. It is up to the OEM/Vendor/Manufacturer to implement features that are not "mandatory" by the OS creator, Google.
Why they didnt do it we will never know. It might be a way to reduce development costs. Maybe Sony thinks that their target market will only use the TOF for photography and not for anything else.
So there are no other apps that can take advantage of something that to the apps knowledge does not exist. Only Sony apps can "see" the TOF sensor, it is not exposed outside of that. No other apps will be able to see it unless they know how to access whatever API Sony maybe using. Or maybe Sony just access the TOF sensor directly in the camera app only, there is no API involved.
Maybe a third party rom can expose it if they can figure out how to access it, either via drivers released by Sony, or by their own trial and error, reverse engineering, etc.
