Apple today seeded those registered to beta test iOS 11 with the fourth build of iOS 11.2.5. This comes nearly a week after the third beta was released to the same party.
To install the new build on your registered device, head over to Settings > General > Software Update. Tap “Download and install” next to the iOS 11.2.5 beta listing and you’ll be good to go. I recommend jumping on a Wi-Fi network first alongside plugging in your device beforehand as a) you don’t want data overcharges on your bill and b) you don’t want your phone or tablet to die during the installation process.
So far, we haven’t spotted anything new in the build. The usual system stabilities and bug fixes are under the hood, but nothing user-facing is. Of course, we’ll let you know of anything notable.
