iOS 17.1 released, fixes screen ghosting error

Apple has just released iOS 17.0.2 specifically for the iPhone 15 series to fix the problem of the new device freezing with the Apple logo on the screen during the process of transferring data from an old iPhone to a new iPhone.

Apple has released iOS 17.1, the first major update version of iOS 17 since the platform's release on September 19. iOS 17.1 has a capacity of about 1.5 GB if upgrading from iOS 170.2.

According to Apple's announcement, iOS 17.1 has 14 changes, of which five are about new features, and nine are improvements and bug fixes.

One of the bugs fixed is an issue that could cause burn-in on the screen. Although Apple did not mention it specifically, many people believe that it is an issue related to image retention, causing ghosting on the iPhone 15 screen recently. More time will be needed to evaluate the effectiveness of this fix.

Some other issues that iOS 17.1 is claimed to fix include "Important Locations" setting being reset when connected to Apple Watch, an issue causing the keyboard to respond poorly, caller names not being displayed, the problem of losing purchased ringtones.

Some new features on iOS 17.1 include:

Transfer files via AirDrop even when the two devices are not near each other, via the Internet, which Apple introduced at WWDC in June.


Standby mode has been improved with the option to control screen-off time. However, this feature only supports iPhone 14 Pro and 15 Pro models.

The Music app expands with a number of new features including favorites, cover art, and song suggestions at the end of playlists.

iOS 17.0.2

Apple has just released iOS 17.0.2 specifically for the iPhone 15 series to fix the problem of the new device freezing with the Apple logo on the screen during the process of transferring data from an old iPhone to a new iPhone.

Specifically, when users choose to transfer applications and data from old iPhone to new iPhone running iOS 17 or iOS 17.0.1, during the setup process for the new iPhone 15 series phone, the device may freeze.

This error will not occur if the user manually sets up the new iPhone 15 series device and downloads all individual apps from the App Store.

Therefore, if you just bought an iPhone 15, don't transfer data from the old device but check to see what software the device is running. If it is iOS 17 or iOS 17.0.1, please update to the latest version iOS 17.0.2 so you don't have to worry about any problems.

To check which version your iPhone 15 is running, you must skip the step of synchronizing data and initial settings, go to the main screen > Settings > General settings > Software update and check.

Note, iOS 17.0.2 is only for iPhone 15 series. Maybe iPhone 15 will prompt you to update right during the setup process, then click to agree to upgrade the operating system.


Apple will try to roll out this latest software version to all iPhone 15 users globally as soon as possible. Some markets have already received this version, but there are also markets that have not.
