the iphone 4 supports up to ios 7, released in september 2013. due to the relatively aged hardware of the iphone 4, certain features available on newer iphone models are not available on the device; as of ios 7, they include siri, 3d maps and turn-by-turn navigation, airdrop, airplay mirroring, live camera filters, panorama mode and certain visual effects introduced by ios 7, such as the blurring of translucent interface elements, the parallax effect on the home screen, and live wallpapers. while still subject to the same limitations, ios 7.1 did bring some slight performance improvements to the operating system on the iphone 4. ios 7, specifically ios 7.1.2, is the last version of ios to support the iphone 4. unlike the iphone 4s, the iphone 4 did not receive the ios 8 update due to performance issues.
