However, the transition to 6.0.1 on the Z00UD was not without its growing pains. Users on ASUS’s official ZenTalk forums frequently reported early issues, including a "ghost touch" bug that affected screen responsiveness after the update and an aggressive battery optimization that sometimes killed push notifications for essential apps like email or WhatsApp. ASUS’s ZenUI overlay, while feature-rich, remained a heavy skin that clashed with the cleaner "Material Design" aesthetic of stock Marshmallow, leading to a sense of software dissonance. Nevertheless, ASUS diligently pushed incremental patches (e.g., firmware version 6.0.1.235) that eventually resolved the critical bugs, solidifying Marshmallow as the most stable and reliable operating system the device ever received.
