1. Understand the limitations. Lenses do not work with the majority of Android smartphones, and only with recent iPhones. If you don't have a new device, there's a good chance that you won't be able to get Lenses to work.
• The iPhone 4, 4S, and iPad 2 are not supported.
• Lenses requires Android 5.0 (Lollipop) or later for Android devices. Even with 5.0+ and recent devices, some users report that the feature still will not work.
