iPhone, iPad, and iPod touch users are dealing with installation issues, abnormal battery drain, lag, connectivity issues, and problems with Touch ID. These are all common iOS problems and most of them can be fixed in minutes.
In this guide to iOS 12, 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, iOS 12.3.1, iOS 12.3.2, iOS 12.4, iOS 12.4.1, iOS 12.4.2, iOS 12.4.3, iOS 12.4.4, iOS 12.4.5, iOS 12.4.6, iOS 12.4.7, iOS 12.4.8, iOS 12.4.9, iOS 12.5, and iOS 12.5.1 problems we’ll take you through the most glaring issues.

We’ll also touch on the state of the iOS 12 downgrade and a few things you can expect from Apple and the next version of iOS 12.
iOS 12.5.1 Problems
While some iOS 12.5.1 problems are brand new, others have carried over from previous versions of iOS 12.
The iOS 12.5.1 download is getting stuck on some iPhone, iPad, and iPod touch models. If this happens, you’ll want to hard reset your device. This usually resolves the problem and gets the download moving again.
We’re also seeing reports about Wi-Fi and Bluetooth issues, GPS problems, 3D Touch problems, landscape problems, user interface lag, lockups, freezes, app crashes, AirPlay problems, an issue where the Messages app is sending messages to unintended recipients, and problems updating apps on the App Store.
Months ago, Apple acknowledged a widespread, extremely problematic, eavesdropping FaceTime issue impacting several versions of iOS 12 (iOS 12.1-iOS 12.1.3).
In a nutshell, the bug lets you call someone via FaceTime and hear the audio coming from their phone before they pick up the phone.
Apple addressed the problem in iOS 12.1.4 and those who want to continue using Group FaceTime must download a newer version of iOS 12 for it to work. The feature is permanently disabled on iOS 12.1-iOS 12.1.3.
Some iOS 12.1.4 users were still having issues with Group FaceTime, but Apple’s iOS 12.2 update fixed them. If you skipped iOS 12.2, iOS 12.3, iOS 12.3.1, iOS 12.3.2, iOS 12.4, iOS 12.4.1, iOS 12.4.2, iOS 12.4.3, iOS 12.4.4, iOS 12.4.5, iOS 12.4.6, iOS 12.4.7, iOS 12.4.8, iOS 12.4.9, and iOS 12.5, make sure you download iOS 12.5.1. The fixes from iOS 12.2 are baked into your upgrade.
If you haven’t downloaded iOS 12.5.1 yet, we recommend preparing your device for the download. A little prep can go a long way toward preventing problems.
To assist you we’ve put together a step-by-step pre-installation process and our checklist will take you through the most important things you need to do before you install iOS 12.5.1.

Some iOS 12.5.1 problems can be fixed in minutes.
If you’re running into trouble on iOS 12.5.1, there’s no need to panic. We’ve put together a list of fixes for the most common iOS 12 problems. It’s a great place to start.
We’ve also released a list of tips that could help you improve your device’s performance and also one that outlines ways to fix iOS 12 battery life problems.
- Fully unlocked and compatible with any carrier of choice (e.g. AT&T, T-Mobile, Sprint, Verizon, US-Cellular, Cricket, Metro, etc.).
- The device does not come with headphones or a SIM card. It does include a charger and charging cable that may be generic, in which case it will be UL or Mfi (Made for iPhone) Certified.
- Inspected and guaranteed to have minimal cosmetic damage, which is not noticeable when the device is held at arms length.
- Successfully passed a full diagnostic test which ensures like-new functionality and removal of any prior-user personal information.
- Tested for battery health and guaranteed to have a minimum battery capacity of 80%.
If you’re unable to find a fix for your problem in our guides, you should go to Apple’s discussion forums for help. If Apple’s forums aren’t helpful, you can get in contact with Apple Support via Twitter or via the company’s website.
If Apple’s online services fail you, you might want to schedule an appointment to see a Genius at your local Apple Store if it’s open.
They should be able to diagnose your issue in minutes and provide you with a fix or a replacement depending on your warranty and problem.
You Can’t Downgrade from iOS 12.5.1
If you run into trouble on iOS 12.5.1 you no longer have the ability to downgrade to the previous version of iOS 12.
Apple has stopped currently signing on iOS 12.5 which means you can’t bring your device’s software back in an attempt to improve performance.
Unfortunately, the company’s also closed off the downgrade path back to iOS 12.4.9, iOS 12.4.8, iOS 12.4.7, iOS 12.4.6, iOS 12.4.5, iOS 12.4.4, iOS 12.4.3, iOS 12.4.2, iOS 12.4.1, iOS 12.4, iOS 12.3.2, iOS 12.3.1, iOS 12.3, iOS 12.2, iOS 12.1,4, iOS 12.1.3, iOS 12.1.2, iOS 12.1.1, iOS 12.1, iOS 12.0.1, iOS 12.0, and iOS 11 so there’s no way back to those updates either.
For more about how the downgrade process works, take a look at our detailed walkthrough.
iOS 14 and iPadOS 14 come with performance upgrades and they could have a noticeable impact on your device’s overall performance.
If you’re using an iPhone 6, iPhone 6 Plus, iPhone 5s, iPad Air, iPad mini 3, iPad mini 2, or iPod touch sixth-gen, you’re stuck with iOS 12.
It’s unclear when Apple plans to release a new version of iOS 12. We could see Apple release a new version of iOS 12 down the road, but that’s far from guaranteed.
If your device is really struggling on iOS 12.5.1, keep an eye out for a new release.
