Moving to iOS after setup is a relatively simple process. Firstly, ensure that your new iPhone 14, iPhone 14 Pro, or iPhone 14 Plus is powered on and that you have an active Wi-Fi connection. Then, on your old phone, go to "Settings", select "General", and choose "Reset". Next, tap on "Erase All Content and Settings". You may be prompted to enter your passcode or Apple ID password to initiate the process.
Once your old device has been erased, you can begin the process of moving your data to your new iPhone. Follow the on-screen prompts on your new iPhone 14, iPhone 14 Pro, or iPhone 14 Plus and choose "Move Data from Android". You can then download the "Move to iOS" app on your old Android device, follow the instructions to connect the two phones, and begin transferring your data. This includes your contacts, messages, photos, videos, and other content.
Once the transfer is complete, your new iPhone will prompt you to sign in with your Apple ID and set up additional preferences. You may also be prompted to download any applications that you previously had on your Android device. Simply follow the prompts to complete the setup process and you'll be ready to use your new iPhone 14, iPhone 14 Pro, or iPhone 14 Plus.
