Nothing has officially begun rolling out its highly anticipated Nothing OS 4.0 update to the Phone 3a and Phone 3a Pro, bringing a wave of enhancements aimed at improving everyday performance and device stability. Built on Android 15, the new update introduces an optimized interface, faster animations, improved battery management, and better multitasking capabilities.
Users will notice smoother transitions and a cleaner visual layout, a hallmark of Nothing’s minimalist design philosophy. The update also features enhanced privacy controls, upgraded app permissions, and more consistent background activity monitoring to improve battery endurance.
Bug fixes include improvements in network reliability, reduced app crashes, better Bluetooth connectivity, and refined camera performance. Several users had previously reported lag during heavy usage, an issue Nothing claims to have addressed with deeper system-level optimizations.
The rollout is phased and will reach all devices in the coming days. With Nothing OS 4.0, the company reinforces its commitment to delivering a fluid, customized Android experience focused on speed, efficiency, and user simplicity. Early feedback suggests the update is one of the most stable releases yet for the 3a series.
