I am looking for an app that can emulate another android device.

A few years ago I used vmos but:

• it looks really sketchy
• it requires an account
• quick online search tells me some features are locked behind a paywall

I looked for alternatives but they all seem pretty sketchy and I will propably login with a Google account so idk.

My requirements are:

• At least Android Nougat (7.0+)
• GMS
• pass the Google security checks (I think it was called safetynet at some point
• not to slow as I want to play a game

The reason I need this is that I want to use a modified version of a game next to the original version.

I hope someone has a suggestion for me,
Thanks in advance.
