A regulatory investigation into Apple's software warranty practices has been escalated. The probe is tied to complaints about an iOS 18 update that allegedly damaged iPhone functionality. Users reported screen display and microphone malfunctions after the update, and were forced to pay for repairs as Apple does not offer a warranty on software.

The Central Consumer Protection Authority had received a wave of complaints about the issue. The regulator has now formally notified Apple that the matter will be subject to a detailed investigation.

Further details about the investigation are available from the source, including the timing of the iOS 18 rollout and the regulator's actions.
