Most People Should Avoid the iOS 11.3 Beta
The iOS 11.3 beta might be tempting, but most people should avoid the pre-release version of iOS 11.3, especially now with the official release as close as it is.
Trying out pre-release software is a great way to get familiar with changes, test performance and impress your friends, but this is a beta and early software can and probably will cause problems on your iPhone, iPad, or iPod touch.
If you rely on your phone or tablet to get you through a day of school or work, you should stay put on iOS 11.2.6 or whatever version of iOS you're currently running.
