is an augmented-reality game. If AR is enabled, keep the Pokemon centered on your screen, holding your phone as still as possible. Use a gentle fingertip swipe in a straight line toward your target. You want to time your toss so that the ring around the Pokemon is contracted to its smallest when you connect. Green is best, yellow more difficult, and red a very difficult capture.
To make the capture process easier, you can switch off AR/camera mode in Pokemon Go. You can continue to walk and try to capture the Pokemon, but if you lose connection to the server in low-signal areas, you may lose the Pokemon
