Avoid Android 5.0+ (Lollipop). The P970’s TI OMAP 3630 processor cannot handle ART runtime efficiently.
By late 2011, Google had released Android 4.0 Ice Cream Sandwich (ICS), a massive visual overhaul that introduced the Holo dark theme and virtual on-screen buttons. Optimus Black owners waited with bated breath.
LG was initially hesitant. The P970 had a single-core TI OMAP 3630 processor, and many manufacturers claimed single-core devices couldn't handle ICS smoothly (a claim later proven false by developers).
Eventually, LG relented. In late 2012, the official Android 4.0.4 ICS update began rolling out. It was a transformative update for the UI, bringing the modern "LG Optimus UI 3.0" to the device. It looked slicker, felt faster, and utilized the Nova screen better.
However, this was the end of the official road. When Google announced Android 4.1 JellyBean, LG drew a line in the sand. They declared the hardware outdated and ceased official support. The story for the average consumer ended here, but for the enthusiast, it was just the beginning.
In the first half of 2011, the LG Optimus Black (P970) was a head-turner. It was marketed heavily on two pillars: its incredibly bright 700-nit "Nova" display and its razor-thin profile. It was the anti-thesis of the bulky smartphones of its era.
When the device first shipped, it ran on Android 2.2 Froyo. While Froyo was functional, it felt somewhat mismatched with the phone's premium aspirations. The user interface was LG’s early "Optimus UI," a somewhat clunky overlay that tried to mimic the iPhone’s aesthetic but lacked refinement.
However, the P970 was significant because it was one of the first devices to herald LG’s new design language: "L-Style." This design philosophy focused on rectangular aesthetics, floating mass technology for lightness, and metallic accents. For the firmware story, this meant LG had a vested interest in making the software match the premium hardware.
