I have summarized the following problems and solutions, hoping to help you adapt to the new operating system as soon as possible.
1. Save the old information
IOS 8 has added a new information management mechanism, mainly because old information can be automatically deleted on time to save storage space. However, many users prefer to retain old information for emergency purposes, so we can modify it in the "settings-information-retention information" project, including 30 days, 1 year, and permanent retention.
2. Turn off the "input prediction" function
The so-called "QuickType" feature enables the built-in input method of iOS 8 to intelligently associate features. Of course, sometimes the actual results are not ideal. If you do not want to use it, you can turn off the input prediction function in the "settings-General-keyboard" option.
3. Permanently delete the photo
In the photo library of iOS 8, we see a new "recently deleted" album, which is a feature of the Mac system iPhoto application to prevent accidental photo deletion. But one problem is that the deleted photos will remain in the recently deleted album and will disappear completely after 40 days. In addition to security risks, it also occupies the storage space of your device. We can go to this album and choose to delete the photo. Unfortunately, this function is disabled without any related options.
4. Slow speed
Some users report that devices will slow down after iOS 8 is upgraded. In addition to psychological effects, it may be because the system retains the relationship between previous settings. Therefore, we can enter the reset item in the settings to restore the device settings to the factory stage, which may be helpful for improving the speed.
