The iOS 12.3.1 update could have a significant impact on your device’s performance. Some you should install the update right now, but others might want to wait a few hours, a few days, or, in some cases, a few more weeks before making the move.
iOS 12.3.1 is now available for iPhone, iPad, and iPod touch models and Apple’s latest update comes with a short list of important bug fixes for your device.
This is a point upgrade which means the update is extremely small. Those of you moving from iOS 12.3 are looking at an 80MB download.
iPhone, iPad, and iPod touch users moving from older versions of iOS will see a larger download size because the features and fixes from the updates you skipped are baked into your version of iOS 12.3.1.
Those of you dealing with issues on iOS 11, iOS 12.0, iOS 12.0.1, iOS 12.1, iOS 12.1.1, iOS 12.1.2, iOS 12.1.3, iOS 12.1.4, iOS 12.2 or iOS 12.3 could see a huge turnaround after installing iOS 12.3.1.
That said, while some of you will see a boost, others might run into bugs and performance issues. iPhone, iPad, and iPod touch owners are reporting various problems with the software.
If you’re really struggling you can try downgrading to iOS 12.3. Apple is still signing on the update which means you can use a loophole to drop back to the previous version.
Apple isn’t signing on anything older than iOS 12.3 so those of you on old versions of iOS should be extremely careful. Once you move, there’s no way back.
There are plenty of reasons to install iOS 12.3.1 on your device today. There are also some reasons why you might want to hold back and wait.
If you’re currently debating a move to iOS 12.3.1, allow us to walk you through each one of these reasons right now.
