7 Things to Know About the iPhone 8 iOS 12.4.1 Update



Apple’s iOS 12.4.1 update could have a big impact on your iPhone 8’s performance.

iOS 12.4.1 is the latest version of iOS 12 and it’s available on the iPhone 8 Plus and iPhone 8.

The iOS 12.4.1 update is a small maintenance release with a single change on board. That said, some iPhone 8 and iPhone 8 Plus users are seeing improved performance after installing the new update. Others are running into trouble.

As we push away from the release date there’s a growing list of complaints about bugs, glitches, and performance issues. Some of these issues are minor annoyances, other problems are much bigger.

If you’re currently having a great experience on iOS 12.4, iOS 12.3.2, iOS 12.3.1, or an older version of iOS, you need to approach iOS 12.4.1 with caution.

You can’t predict exactly how the software will run on your phone so you’ll want to be ready to face problems head on. This is especially important now that Apple’s stopped signing on some of the older versions of iOS 12.

Once you make the move to iOS 12.4.1, you can downgrade to the previous version, but you can’t go back to older updates like iOS 12.3. Apple is working on new firmware, but it could take weeks for the company to trot out a new version of iOS.

With all of that in mind, we want to take a look at the iPhone 8 iOS 12.4.1 update’s performance, problems, changes, and more.

The iPhone 8's iOS 12.4.1 update requires a small download if you're moving from iOS 12.4. 

If you're moving up from an older version of iOS, you can expect a bigger download and a lengthier installation because the features and fixes from the updates you skipped are baked into your version of the iOS 12.4.1 update.

As for the iOS 12.4.1 update's performance, it's currently stable on our iPhone 8 models. 

We've been using the update for a short time and we've been looking at key areas of performance like battery life, UI speed, and connectivity. 

Thus far, battery life is holding up. We haven't experienced any abnormal drain and we're able to get a full day of use.

Wi-Fi, Bluetooth, and GPS are all working normally and we haven't noticed slow speeds or an increased number of dropped connections. These are common issues after a software update. 

The software is fast and we haven't noticed any lag. Control Center, Notifications, and the keyboard are places where we often see lag, but nothing has popped up on our devices yet. 

Given its performance and what's on board, we're recommending iOS 12.4.1 to most iPhone 8 and iPhone 8 Plus users. 

If you need some additional feedback please take a look at our list of reasons to and not to install the iOS 12.4.1 update on your device right now.

    I am paying for a phone I can’t use thanks to the new 12.2 upgrade. I get garbled messages on calls or can’t call at all. My phone shows no service where I was able to get it before this download. We are not permitted to go back to 12. You need to fix this now. This is happening to my friends and family and perhaps class action suit needs to be addressed.

    My phone is lagging whenever I use my Messages app. I’m using an iPhone 8 with iOS 12.2 version. The cursor hangs in a certain place, and deleting a text, lags. Also, sometimes the buttons on the touch keyboard, hangs.

    iOS 12.2 seemed to be the demise of my 8 plus. Screen would go black, phone would reset a couple times then go black and totally dead for hours. Then came back to life on its own a few times now totally dead for a couple of days. No help from apple- it’s at 14 months. Previous phone was a 4 and lasted me five yrs and still works.

    I have had multiple issues with my iPhone 8 since updating to iOS 12.2! I have been on Straight Talk Wireless for about 5 years. The first thing I noticed was I no longer had data capability. Then I noticed texts and phone calls would not come through. Reading various help topics from Apple, as well as Straight Talk and online forums; most suggest the carrier is able to resolve the issue. After more than 25 phone calls, 3 sim cards (including the original), a trip to the Apple store (one hour drive), several types of resets and Apple support helping through calls; I am down to no longer having the use of Visual Voicemail, no matter what. My husband has iPhone X, my oldest son has iPhone 8, my youngest son has iPhone 8+, and we all have Straight Talk Wireless. My phone is the only one with ANY issues.

    I have updated to iPhone 12.3 on my 8 plus. I can now not connect to any apps that use wi-fi in my home. Bluetooth and GPS work fine but facebook, Twitter etc just say no internet connection. The internet is working okay as my PC and MacBook work fine both on Wi-fi and Ethernet. My iPhone is now 50% useless and no more than an expensive mobile phone.

      I bought an New in Box unlocked iPhone 8 on eBay several months ago and didn’t activate it until last week. I updated the phone to iOS 12.3.1 during activation, and I am unable to access data when I’m away from my home or work network. There’s no data capabilities while driving. I am a Straight Talk customer for years and started there for help. They directed me to Apple Support where they were as helpful as possible but I am still having issues.

    Now my phone shut off my Bluetooth speakers. All of them. Doesn’t just disconnect from bluetooth, each speaker will disconnect and physically shut down. What the actual bleep . I have tried EVERY troubleshooting tip that I could find except the last one which is take my phone to an Apple Store, which I do not have access to where I live.
