If you haven’t updated to iOS 9.3.3 yet, update now!
Apple fixed a bug that allowed a hacker to take over your iPhone by simply texting or emailing you a malicious TIFF picture file. The bug was made public after being discovered by Tyler Bohan, a researcher who works for Cisco’s security unit. He discovered that older versions of iOS and OS X contain an exploit that could theoretically allow a media file like a photo or video to defeat built-in software security measures and take over your device. The malformed media file could arrive as an email, iMessage, webpage, or other apps. If the malicious TIFF image is viewed on the device the hacker could gain full control of the device, including accessing passwords without you knowing. Apple has fixed this exploit in iOS 9.3.3. If you haven’t updated yet, you are still at risk.

An added benefit, I am hearing that after updating to 9.3.3 that some people are seeing performance improvements – a faster iPhone is a good thing 🙂
