The iPhone SE iOS 12.4 update is an important milestone upgrade, but the latest version of iOS 12 is causing problems for some iPhone SE owners. If you’re thinking about moving your iPhone SE to iOS 12.4, make sure you’re fully prepared for the move.
iOS 12.4 could have a noticeable impact on your device’s performance. Most iPhone SE owners should upgrade to iOS 12.4, but some might want to take a rain check.
iOS 12.4 is plagued with various bugs and various performance issues and we expect the list to grow as more people decide to download and install the new firmware.
We’ve been using the iPhone SE iOS 12.4 update for a short time and performance has mirrored the experience we saw on previous versions of iOS 12. We haven’t run into any significant problems, but those thinking about upgrading still need to be careful.
If you run into issues you can try downgrading to iOS 12.3.1 or iOS 12.3. However there’s no way back to iOS 12.2 or any of the previous versions of iOS 12.
If you’re having a good experience on iOS 12.2-12.0, approach the iOS 12.4 update with caution.
In this guide we’ll take you through these problems and provide you with our impressions of the iOS 12.4 update’s performance on our iPhone SE.
Our guide will also walk you through some essential tips, what you need to know if you want to jailbreak your iPhone SE, and what you can expect from Apple in the weeks ahead.
iPhone SE iOS 12.4 Impressions & Performance
If you're moving your iPhone SE from 12.3.1 to iOS 12.4 you can expect the installation to finish in 10 minutes or so.
If you're moving your iPhone SE from an older version of iOS like iOS 12.2, you can expect your download and installation to take a bit longer. That's because the features and fixes from updates you skipped are baked into your version of the update.
