Custom ROM users who enjoy a Pixel-style UI, modern Android features, and strong system control have plenty of choices—but few ROMs balance polish and power as well as ASCP (Android Simple Clean Project). With the release of ASCP v4.3 Official, based on Android 16 and updated on 14 December 2025, the Poco F3 (Alioth) gets a ROM that feels refined, fast, and genuinely ready for daily use.
ASCP doesn’t try to reinvent Android. Instead, it focuses on delivering a clean Pixel-like foundation, layered with thoughtful features that actually improve usability. This release continues that philosophy, adding smoother animations, improved integrity handling, modern UI refinements, and a long list of practical enhancements—without sacrificing stability.
In this article, we’ll take a proper look at ASCP v4.3: what it offers, what’s new, how it performs in real use, and who this ROM is best suited for.

- Keep the system clean

ASCP v4.3 continues this approach on Android 16, offering a ROM that feels modern, responsive, and surprisingly polished for everyday usage.
