Early buyers of Apple premium foldable phone the iPhone Duo are facing unexpected screen troubles shortly after opening their new devices. Social media forums like Reddit and tech communities are flooded with complaints showing permanent vertical lines and screen cracking along the folding area.

Multiple users reported that the folding hinge felt unusually stiff during normal daily use. When forced past this sudden mechanical resistance, an audible popping sound was heard before bright pixel lines appeared across the inner display. Some owners claimed their screens failed within just a few hours of unboxing and after fewer than twenty folds.

Tech repair analysts examining early teardowns suggest internal hinge components or microscopic debris under the flexible panel might be applying uneven pressure onto the fragile folding glass. While screen replacement costs outside warranty are extremely high, Apple is currently offering replacements for genuine manufacturing defects. However, stock shortages mean affected customers may face delays getting new units.

Although the issue seems limited to specific early production batches, tech experts advise owners to handle their expensive foldable devices carefully. Industry observers at Nation Bizz will continue monitoring Apple official responses and stock updates closely.
