4 Reasons Not to Install iOS 11.2.1 & 10 Reasons You Should

Apple’s iOS 11.2.1 update is a tiny maintenance release, but it could have a significant impact on your device’s performance. While many of you should install the iOS 11.2.1 update today, others might benefit from waiting a few more hours, a few more days or, in some cases, a more few weeks.

Many iPhone and iPad users have been dealing with iOS 11 problems and Apple’s latest update comes with bug fixes for lingering issues. Namely, a potential security issue with the HomeKit platform.

iOS 11.2.1 is a maintenance release which means it’s a small download for all iPhone, iPad, and iPod touch models. If you’re coming from iOS 11.2, your update is just a few megabytes. It’s just 68MB for the iPhone X and around the same for other iPhone models.

Your iOS 11.2.1 update will be even bigger if you skipped iOS 11.0, iOS 11.0.1, iOS 11.0.2, iOS 11.0.3, iOS 11.1, iOS 11.1.1, iOS 11.1.2, or iOS 11.2. The fixes and features from those updates are baked into your version of iOS 11.2.1.

iOS 11.2.1 Update: Should You Upgrade?

iOS 11.2.1 is a tiny update, but Apple’s maintenance upgrades can have tremendous impact on your device’s performance. Some of you could see a boost, some of you could see performance issues. The iOS 11.2.1 update fixes bugs, but it’s already causing problems for some iPhone and iPad users.

If iOS 11.2.1 starts causing problems on your device you can try dropping back down to iOS 11.1.1, iOS 11.1.2, or iOS 11.2. Unfortunately, Apple’s permanently closed off older versions of iOS and Apple’s decision to close off those updates puts an even greater importance on your move to iOS 11.2.1.

There are plenty of reasons to consider installing iOS 11.2.1 right now. That said, there are also some reasons why you might be better off holding out. Temporarily or permanently.

If you’re on the fence about upgrading your iPhone, iPad or iPod touch to the latest version of iOS, allow us to walk you through the best reasons to and not to install it right now.

Install iOS 11.2.1 If You Use HomeKit

Install iOS 11.2.1 If You Use HomeKit

Apple's iOS 11.2 update fixed several problems, but it also brought some problems of its own including a potentially nasty zero-day iOS HomeKit vulnerability.

The vulnerability, discovered by Tian Zhang, allowed for unauthorized control of HomeKit accessories including garage door openers and smart locks.

Last week, Apple rolled out a server-side fix, but the company's restored full functionality with the release of iOS 11.2.1.

If you use HomeKit and value your home security, you'll want to install the iOS 11.2.1 update right away.

      DO NOT install ios 11! It is a giant step for Apple but a HUGE step back for phone users.
      The most annoying thing is that you no longer can check your voicemail directly you have to CALL AND LOG IN TO iToons. (Can you spell ads.)

      The whole ios 11 system is a giant money grab by Apple. Much as I resent Google’s android I may have to go back to it.
      What we really need is an alternative provider (available in the rest of the world but not here). This is no longer “the land of the free.”

      (double tapping the home button to bring down the top portion of the screen so it’s easily accessible with one hand) I thought this handy function was to show what apps. I have open, and to close if I like. At least that’s what it does on my iPhone 5s running iOS 10.3.3. What are you talking about?

    You actually MUST wait if you’re out of your country.
    I travelled from the US to Ireland and got an update that I wasn’t supposed to get because they do everything by location! Thank goodness it wasn’t bad, but be careful, you can fall into that trap! Maybe because Jony Ive is from the U.K., they get updates first! All I know is I got 10.3.2 before anyone else!!! :)

    Siri is so irritating. The translation feature has a funny example–exactly why this kind of translating often gets it wrong. “Where is the bathroom?” is literally translated. The place someone would point out for you would have nothing to do with a toilet. It would be a place to take a bath.

    Apple is more concerned about hiding off shore profits than making good products anymore. Sad.
