Sony recently released updates to Android 7 for their phones. However, if today someone would like to update your phone, it may be impossible. As it turns out, the update contains several errors.
As reported by the company itself in an official statement, the update causes "inconsistencies related to audio playback via third-party apps and SD card encrypted data read performance". That's why firm decided to remove for now update files dedicated to Xperia Z5, Xperia Z3+ and Xperia Z4 Tablet.
Sony hasn't yet announced when files are planned to be reuploaded on servers.
