So I wanted to post a quick follow up to my last post about Pokemon GO as I’ve seen a lot of people questioning how to turn off AR mode in Pokemon GO (or how to turn it back on). The option to toggle AR mode only shows up when you’re attempting to catch a Pokemon. Once you’re near a Pokemon and tap on it you’ll see a slider labeled AR in the top right corner of your screen, and tapping this will turn AR mode on or off.
Hope this helps those who are still trying to figure it out.

When I turn on AR, my pokemon disappears from my screen and I can’t take a picture of it. Any ideas?
I think it’s a bug. I’ve had that happen too and I’ve had to close the app. Once I do the Pokemon is gone for good though
Same thing happens to me. Then again my tablet doesnt have gyroscope. So if you dont have á gyroscope what then you can do is print out AR paper looks like a bunch of random lines or a QR code. And then with the help of that you can see your Pokemon.
When I go to catch a Pokemon, that toggle does not exist. I have an iPhone. I want AR back 😦
Same problem. Following to see if anyone else has a solution. The toggle is not on the screen. I also have an iPhone.
