Refresh Rate Changer 30 by RC Modz aims to give quick control over display refresh rates (notably forcing 30 Hz) to save battery or test performance. While potentially useful, installing third‑party APKs carries security and stability risks; prefer official settings or well‑reviewed tools and proceed with backups and caution.
: The app cannot physically change your screen's hardware; if your panel is capped at 60Hz, forcing 120Hz through software may cause visual glitches or no change at all. refresh rate changer 30 by rc modz apk top
