Justin Bieber has expressed frustration with Apple’s Messages app, particularly its user interface. He humorously threatened to apply a "rear naked choke hold" on Apple employees, citing issues with the design of the send button. The problem arises when users type a message; the microphone icon shifts to a send button. After sending a message, it reverts back to a microphone, which Bieber claims he accidentally hits, resulting in a disruptive beep that interrupts his music. Bieber's main complaint is about having the send and microphone functions in the same spot, which he feels leads to confusion. While some may sympathize with his plight, the majority of Apple users navigate this design without issue. The article suggests that Bieber's difficulty may stem from a lack of dexterity rather than a fundamental flaw in the app. However, it acknowledges that combining multiple functions in one location can generally be problematic from a user experience standpoint. The piece touches on a broader concern regarding Apple's recent design choices, particularly the new Liquid Glass effect-based UI, which hasn't received positive feedback. Highlighting Bieber's unsolicited UX advice raises eyebrows, considering his celebrity status and the oddity of a pop star critiquing a tech giant’s design.
