FaceNotify by K4CZP3R

Hi, I'm really happy to show you my app.
This app will hide content of your notifications and show it only when it recognizes your face!

I really wanted this IOS-feature on my OnePlus, but could not find an app for this. So I wrote this app!
Installation guide on YouTube

It works with OnePlus 5/5T/6/6T/Xiaomi RN7/Samsung S8/S9/S9+/S10. Other phones are not tested, but it will probably work.
(OS Supported: OxygenOS, crDroid, OmniROM, MIUI)

Send me your logcat dump if you want to have your phone supported! (adb logcat -d > logcat.txt)
Create logcat dump after locking and unlocking your device using face unlock
Upload to gist.github or pastebin and send it to me via PM.
You can send my app log if you are having issues! (Enable it in settings, then send file named Documents/facenotify.txt)

OnePlus and their Oxygen OS Android modification is known as maximizing the stock Android experience. This may be true on the UX front but the exact opposite is valid for background process limits. ~https://dontkillmyapp.com/oneplus
So, try to follow this guide if the service gets killed!

If it still does not work, you can try to install facenotify as system app (will add magisk support for it in the next release!)

Great idea. Thanks for making this.
Just FYI for other: On the 6T, I only saw a blank page when I first opened the app. Waited a bit and I could see the buttons.

Anybody confirm if it works on 5t?
Someone on the reddit post confirmed that it works. Although it will say "not supported" in the second box

Oh damn never thought this would be possible. One caveat though. The transition from hidden to showing the notification content is not smooth. Actually there isn't even an animation. Could you do something with that or is it a limitation of Android?

Does not seem to be working for me on OnePlus 6.

First time I tap start service, it gives me an error my device is not supported. Second time it activates but does not hide any notifications on lock screen.
Try to change some settings in app, it may be a bug. (will be fixed in the next release)

It's a little inconsistent on OOS 9.0.3. The persistent notification is there, battery optimization is off for this app but somehow it still doesn't work after a period of time and I have to go into the app to disable and then re enable the service for it to work again.
