Many users are upgrading their iPhone to the latest iPhone 14, and many face some obstacles when it comes to new functions or old function updates.

If you get an iPhone 14 Pro or Pro Max, you might be wondering what a dynamic island is, that little graphic floating at the top of your screen.

You'll need to know what the satellite SOS feature is and how to use it. There are also a few features you should know, such as editing or unsending iMessages, that can be really useful.

Here are some iPhone 14 tips and tricks to get you started:

How to edit or unsend an iMessage message

You can now edit or delete iMessages you've already sent. This feature works for anyone with an iPhone released in 2017 or later. Just make sure your device is running iOS 16 or later, and you can check by going to "Setting", then "General", and then "About".

You have only two minutes to unsend iMessage and 15 minutes to edit the message after it has been sent. This feature doesn't work with SMS text messages, which appear green. The feature only works if the other person you're messaging has iOS 16 or later.

To edit the iMessage message

Open iMessage, press and hold the message you want to edit, and the quick action menu will appear.

Click Edit, and choose Edit To change the message, once you're done editing, tap the blue checkmark.

You can edit a single message up to 5 times, provided it is done within 15 minutes of sending the message.

To cancel sending an iMessage message

OpeniMessage, and press and hold the message you want to unsend, a quick action menu will appear. then tap Undo Send.

Undo Transmission works up to two minutes after sending.

When you try to unsend iMessages sent to someone running iOS 15 or earlier, they'll still see them.

If the person you're messaging is running iOS 16, you'll see a message saying you haven't sent a text message. The person you're messaging won't know what this message is, as long as they didn't see the text when you sent the original iMessage.

Satellite Emergency Calls

In November, Apple launched its satellite emergency SOS service for all iPhone 14 users, allowing users to send text messages to emergency services when they are off the network, whether they are camping in the mountains or driving in a remote area at night. This service is free for the first two years.

How to use emergency satellite calls:

In case of emergency, try calling 911. If you don't have cellular service, your phone will try to connect to another carrier's tower. If that doesn't work, you'll see the option to use Satellite Emergency Messaging.

You can also go to iMessage to text 911 or SOS, then click Emergency Services.

An option will populate, allowing you to click to report an emergency.

Emergency questions will be filled in to help you better describe your condition, the first question will say "What is an emergency?" You will then be able to choose from several options, such as "problem with the car" or "illness or injury". Next, you will be guided through a series of more detailed questions.

You'll have the option to notify your emergency contacts to let them know that you've contacted emergency services, as well as your location and the nature of the emergency. You can also use the Find My app to share your location with friends and family via satellite.

To connect to the satellite, you'll be asked to point your phone at it.
