Instructions

Start by installing the apps :

• Install the latest ARCore from here (download the arm64/v8a variant).
• Install the modded Playground (Android 9+) pack here. After it's installed, you can install missing packs from here.

Now change the phone's fingerprint :

• Using Magisk Manager, install the MagiskHide Props Config module and reboot
• (screen recording) Using a terminal app (e.g.: Termux), type su, press "enter" on your keyboard, and grand root access.
• Type props > press enter > type 1 (to change fingerprints) and confirm by following the instructions.
• Use one of Google's phones. The Pixel 2 fingerprint works very well. OnePlus 3 users can pick the OnePlus 3T fingerprint instead.
• After changing the fingerprint, choose the option to reboot.

After booting, you'll be able to use "AR Stickers" and "Playground" from inside Google Camera or any other AR related app.
