4 Reasons Not to Install iOS 12.4.3 & 9 Reasons You Should

Published

on

The newest version of iOS 12 could have a significant impact on your device’s performance. While some of you should install the iOS 12.4.3 update right now, but others might want to wait a few hours, days, or longer before making the move.

iOS 12.4.3 is now available for the iPhone, iPad, and iPod touch and the upgrade comes with a short list of changes for your iPhone 6, iPhone 6 Plus, iPhone 5s, iPad Air, iPad mini 3, iPad mini 2, or sixth-gen iPod touch.

The iOS 12.4.3 update is a maintenance upgrade and requires a very small download. Those of you moving up from iOS 12.4.2 will see the smallest download size.

If you’re moving from an older version of iOS 12, you’ll see a larger download size because the features and fixes from the updates you skipped are baked into your version of iOS 12.4.3.

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, iOS 12.3.1, iOS 12.3.2, iOS 12.4, iOS 12.4.1, or iOS 12.4.2 could see a turnaround after installing iOS 12.4.3.

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 new software.

If you do run into issues you’re on your own. iOS 12.4.3 is a surprise release for iOS 12-powered devices that didn’t get upgraded to iOS 13 so there’s no telling when, or if, Apple will release a new version.

Apple’s also closed off the downgrade path to iOS 12.4.2 which means there’s no getting off it once you upgrade.

The company isn’t signing on iOS 12.4.1, iOS 12.4, iOS 12.3.2, iOS 12.3.1, iOS 12.3, or any older versions of iOS 12 either. So if you’re moving from an older version of iOS 12, proceed with extreme caution.

While there are plenty of reasons to install iOS 12.4.3 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 12.4.3, allow us to walk you through each one of these reasons right now.

Install iOS 12.4.3 for Better Security

Install iOS 12.4.3 for Better Security

If you're on the fence, this is one of the best reasons to install iOS 12.4.3.

If you value your device's security, you'll want to download iOS 12.4.3 in the near future because it brings important security patches for your device. You can read about them (when Apple posts them) right here

If you missed iOS 12.4.2, you get an additional patch with your upgrade. You can read about the security contents of iOS 12.4.2 here

If you skipped iOS 12.4.1, you'll get its security patch with your iOS 12.4.3 update. You can read about that patch right here

If you skipped iOS 12.4, you get its patches with your iOS 12.4.3 update. 

iOS 12.4 brought 19 security patches to the iPhone, iPad, and iPod touch. If you're interested in the specifics, you can read about them on Apple's security site

If you skipped iOS 12.3, your iOS 12.4.3 update carries iOS 12.3's security patches on board. The iOS 12.3 update brought 23 patches and you can read about all of them right here on Apple's site. 

If you skipped iOS 12.2, you'll get its security patches with your version of iOS 12.4.3.

iOS 12.2 brought a whopping 41 security patches to iPhone, iPad, and iPod touch in March. You can read more about the iOS 12.2's patches over on the company's website

It's important to note that Apple's iOS 12.2 update patched up an exploit that allowed websites to use motion sensors to "fingerprint" devices.

The exploit, discovered by researchers in Europe, uses JavaScript to snag data from a device's accelerometer, gyroscope, and magnetometer when the user visits an infected website. If the attack is successful, a device can be tracked around the internet. 

Fortunately, Apple's patched up the issue. If you skipped it, you'll probably want to move to iOS 12.4.3 soon.

If you skipped iOS 12.1.4, you get four important security patches including fixes for a widespread FaceTime eavesdropping bug that lets you call someone via FaceTime and hear the audio coming from their phone before they pick up the phone.

If you skipped iOS 12.1.3, you get some additional patches with your version of iOS 12.4.3. Again, they're baked into your upgrade.

Apple lists a grand total of 23 patches on board iOS 12.1.3 and you can read about all of them over on Apple's website. 

If you skipped iOS 12.1.1, you'll want to install the iOS 12.4.3 update on your iPhone, iPad, or iPod touch today. 

The iOS 12.1.1 update brought 17 patches for potential security exploits. They'll will help protect your phone. You can read about them here.

If you skipped iOS 12.1, you'll get the 24 patches from that update with your version of iOS 12.4.3. If you skipped iOS 12.0.1, your iOS 12.4.3 update brings two additional patches. Both patches are for potential lock screen exploits.

If you skipped iOS 12.0, and you're still running iOS 11.4.1 or below, your iOS 12.4.3 update comes with a longer list of security updates. 

The iOS 12.0 update delivered 16 patches for security issues. You can read about all of them over on Apple's security page.

In addition to those patches, iOS 12 delivers new security features aimed at protecting you and the data you store on your device. These include:

  • Enhanced Intelligent Tracking Prevention in Safari prevents embedded content and social media buttons from tracking cross-site browsing without your permission
  • Suppresses ad retargeting by reducing advertisers’ ability to identify iOS devices uniquely
  • Strong and unique passwords are suggested automatically when creating an account or changing a password in most apps and in Safari
  • Reused passwords are flagged in Settings > Passwords & Accounts
  • Security code AutoFill presents one-time security codes sent over SMS as suggestions in the QuickType bar
  • Sharing passwords with contacts is easier than ever using AirDrop from Passwords & Accounts in Settings
  • Siri supports quickly navigating to a password on an authenticated device 

Long story short, if you store sensitive data on your iPhone, iPad, or iPod touch, you have some really good reasons to upgrade to iOS 12.4.3 today.

    iOS 12.1 has a SERIOUS security flaw, enabling stealing your contacts via a mere phone call!!! DO NOT UPGRADE!!!

    Hi!
    I have an iPhone SE..and now I have the iOS 12.1
    I am really scared to download this new update 12.1.3, because I’m afraid my phone is gonna crash, get really slow, or something else that makes it worse.
    I think I’ll just wait a little bit more., What do you think?
    It does seem like my battery goes down very quickly..and my phone is not that old (I bought it in the fall of 2017..
    Apart from the battery (and that it dies in the cold.. which it actually always have), it works fine.

    But I miss being able to take Live Photo’s on Facetime!! I have nieces and nephews in other countries, so I really want that back. Is that feature on this new update?

    Hope I’ll get some feedback from you guys!☺️ Is it best to just wait with this update?

    – Diana

      I haven’t updated my ios in a REALLY long time. I’m on 12.1 and I always read about problems that new ios brings and I’m so happy I haven’t updated. I don’t have any problems with connecting to wifi or cellular data and I can still make calls. So it’s up to you if you roll the dice and update. I personally choose not to.

    • BABYGIRL

      Also that new feature screen time could be why your battery drains so fast. Try turning it off.

    Do you guys every provide content without dividing it into multiple pages and 1-2 paragraphs per page? I bet you’d get more quality visitors if you’d actually provide an article on one to two pages. As soon as i see the page 1 of 13 count, I just go elsewhere…

      This is the most important feedback for this website. It’s such a ridiculous effort to get ANY information out of this stupid site. All redundant paragraphs. Click after click for vague, meaningless, not committed information. Why ever bother?

        My thoughts exactly. Article sounds like it was written by an adolescent AI Chinese programmer. Specificilly designed for SEO, told me everything except what I wanted to know.

      Agree with you 100%! The slideshow display should be optional, not the default. Plus, if to be the default, then there should be a single page option.

      I’m not going to waste my time clicking through *15* pages!

      They should have provided a nice table listing the 4 cons and 11 pros!

        i agree. I don’t otimor knowledge to understand an update that is saying tthe same thing over and over. Between that and the pages of advertising I am having difficulty keeping track of what ever new information there is. I also just don’t have the skills to understand what most of the updates.
        If my phone says it will automatically update that is fine. I don’t know what it means or expect me to sit and study and some users expect no futher need to do anything related to update the phone changes and ignore them because they don’t know how to do it. Just expect everything to work.

        It’s because the owner of the site signed up for the crappy Google Ads with the hope 1000’s of morons will actually click on a dumb ad.

        Whenever I see a site with Google Ada on it I know it’s crap!

        Dump the ads and get credibility with readers. Content is king and flooding a site with crap ads that net you pennies is foolish.

    After installing IOS 12.2 onto my iphone x i see a massive improvement, however, when installed onto my iphone 6s the improvement was not noticeable at all

    Big Issue with 12.2, WI-Fi keeps dropping out and wont reconnect. This is to a network that its been connected to for years. This is on both an 8+ and a pad. Was fine on 12.1. Also when trying the ‘fix’ it refuses to accept the password, nothing apart from IOS121.2 has changed for over 5 years. Come on Apple, this is costing me money on data useage.

    iOS 12.3.1 broken safari privacy severely. Safari kidnap me to app store app whenever I click app advertisement link, without any popup alert, without asking, without granting. Till iOS 12.3 I was protected from app advertisement link kidnap by popup alert. and I was able to cancel redirection by just clicking cancel button. It is not possible anymore. I am thinking that this issue may not a bug. If apple made this change intentionally, I will leave iOS world and go into android9+ world. At least, Android is not barring me running code for “VPN based DNS blocking”. This is critical to prevent fingerprinting in any mobile OS. iOS environment is no more a specially good for anti fingerprinting. Zeroing advertisement ID is rather a joke. iOS has been being made for just their money not a privacy. Try to think why Apple is exclusively possessing webviewer (webkit) in the html5 generation. for your privacy? No way!

    If I see “if you skipped …..” one more time . I thought all my updates were current, guess not ‍♀️. Certainly did not deliberately omit them! This article is crap, don’t have time or the brain power to decipher what I SKIPPED, which is a poor selection of words!!! I’m just letting the upgrade download when it downloads and be done with it!!! Agree with the poster who said pro/con list is all we need, not this diatribe of bs!!!

    Not being funny but this article is fairly useless. It lists all the changes IF you haven’t updated through the various versions of iOS12, which most people have so there’s little point reading it. Rather than having 15 pages of un-needed information, maybe try having 1 page of needed information otherwise it’s a waste of most people’s time. Just sayin’.

    Pretty poor exposition of changes in 12.4. There is more that is important to this user than just security. Apple has a long history of trashing good apps and features when they can make more money by doing so. Just look at what they have done to the music apps over the years. Consumers ofApple products are being treated like sheep when we are not told about changes we might not want, and I think it is the responsibility of any so-called “reviewer “ to provide us with that level of information or get out of the business of writing reviews.

    My I phone 7 is performing very poorly. Usually just for general browsing, despite having a strong wi fi connection and / or 4G. “the Circle Of Death” prevails like I’ve never experienced on anything before, really painful experience.
    My near 6 year old I pad air with a chip a good 4 generations behind the phone slaughters my phone for performance. I’ve had enough of it now, and after 10 years of I phones I’m going Android next.

    Strong and unique passwords are suggested automatically when creating an account or changing a password in most apps and in Safari.
