Problems are plaguing iPhone 12 mini, iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max users.

iPhone 12 users are complaining about a wide variety of issues ranging from minor bugs to serious performance issues.

And while some of these issues will likely be resolved by Apple in future iOS 17 updates, more problems will popup as people put more wear and tear on their devices.

In the guide below, you can learn about the current state of iPhone 12 issues, potential fixes for these problems, places to find feedback, and what’s next from Apple in terms of iOS 17 updates.

iPhone 12 Problems

If you’re having issues activating your phone, check Apple’s System Status page. If you don’t see a green symbol next to iOS Device Activation, you’ll want to wait until it’s green and then try activating the phone again.

If it’s green and the process still isn’t working, make sure you have a SIM card inserted in your iPhone. If you’re receiving a “No Sim” or “Invalid SIM” error, you’ll want to head to this guide for assistance.

We’re also hearing about the following issues:

  • Face ID problems
  • Issues with first and third-party applications
  • Exchange problems
  • iCloud issues
  • Visual voicemail problems
  • SIM card issues
  • Bluetooth issues
  • Issues with the touchscreen
  • Charging problems
  • Wi-Fi issues
  • Sound problems
  • Excessive battery drain

Owners of the iPhone 12 mini and iPhone 12, both of which employ a design with aluminum edges, are reportedly seeing discoloration on the chassis. A report from from Svetapple says the color is fading on parts of the edges.

On top of that, iPhone 12 users are complaining about 5G/LTE issues. Some users are saying cellular service is dropping unexpectedly while on-the-go.

iPhone 12 Performance

If you’re thinking about buying an iPhone 12 mini, iPhone 12, iPhone 12 Pro, or an iPhone 12 Pro Max, or if you already own one, you’ll want to monitor feedback from those who have adopted these devices. This feedback will alert you to potential issues with the hardware and software.

We recommend keeping an eye on YouTube, Apple’s discussion forums, social media sites like Twitter, and sites like the MacRumors forums for ongoing feedback about the phones.

If you’re thinking about moving to Apple’s iOS 17 firmware, or if you’ve already made the move, take a look at our guide that covers the latest version of the software.

We’ve also released a quick review that covers the performance of the most up-to-date version of iOS 17, iOS 17.3.1.

How to Fix iPhone 12 Problems

First, take a look at our list of fixes for the most common iPhone 12 problems. It will take you through fixes for common issues like broken Bluetooth and busted Wi-Fi.

We’ve also released some tips to help you improve performance and a guide that could help you improve your phone’s battery life if you start noticing abnormal drain.

If you can’t find a fix for your issue(s) in our guides, you’ll want to check Apple’s discussion forums and see if someone has a fix for your problem(s).

If you can’t find anything there, it’s time to get in touch with Apple. You can get in contact with Apple Support via the company’s website.

If you’d rather explain your issue in person, you should take your phone into your local Apple Store and see if they can diagnose your problem. If you’ve got an Apple Store in your area, you’ll want to schedule a Genius Bar appointment.

How to Downgrade iPhone 12’s Software

If you’re dealing with software problems on your iPhone 12, iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max, you can try downgrading to the previous version of iOS if the option is available.

There's also an expanded Lockdown Mode which will help protect you against cyber attacks.

Apple's also improved sharing permissions and you now have more control over what you share with the apps on your device. 

The company also notes that starting in iOS 17, Voice Memos encrypts the titles of recordings stored in iCloud, in addition to the recordings themselves.

    I have been plagued with problems from WIFI to dropped calls and screen problems. Verizon has been ridiculous to deal with. Probably have at least 20 plus hours invested with no viable solution.

    I have a new iPhone 12 Pro Max and so does my wife… I have had my phone replaced 2 times and they all have the same issue… when booting the phone from off, the Apple logo will flash for a split second at 100% brightness, then the screen goes black for 10 seconds and the apple logo then comes back at normal brightness and the phone boots up normally.. The apple forum has like 10 pages of people complaining of the same problem and some people have had there phone replace 4 or more times. Apple is aware of the problem which now seems to be happening to all new models of the iPhone 12 but they are doing nothing to address it. Still not sure if its a software problem or a manufacturing issue. Put the new release of of iOS 14.4 did not address this issue.
