Help Gyroscope add on

[DaReelTripple]

My LG G3 Vigor doesn't have a gyroscope on it, and I wanted to get Google cardboard, but I can't use it because it doesn't have a gyroscope. Is there a little thing I can plug into my phone to do this? Or do I have to pay someone to install it into my phone? I do not want to buy a new phone, as I don't have the money

Thanks

If it needs a gyroscope, you need to get a phone that has a gyroscope.
