Genymotion is a free Android emulator you can run on Windows/Mac/Linux. I use a fake Samsung Galaxy S7.
You can download apps, including AnyDesk and QuickSupport. (If you preinstall them, put on a different screen than your home screen.)
I would recommend downloading CashApp, PayPal, Amazon, Western Union, Wise, various banking apps etc. on your home screen. When they connect, they will think they might have access to your money.
Things you can do with it:
- Waste time. Have them connect and forget your login, put them on hold and wander off, etc. You can also disconnect your network/pause the VM to frustrate them.
- If they try to send to a PayPal or CashApp account, you can report it.
- Get their IP address and spook them.
- Get their AnyDesk ID and report it. (How?)
