Xiaomi and Oppo smartphones continue to dominate the Android market in 2026, thanks to their feature-rich software and competitive hardware. Xiaomi devices now run HyperOS (with many users still on MIUI), while Oppo phones use ColorOS—both highly customizable Android skins.
One of the most common customizations users love is setting a favorite MP3 song as a ringtone. Default system ringtones can feel boring or generic, while a personal MP3 track makes your phone instantly recognizable and more fun to use. Whether it’s a song chorus, a remix, or a meme sound, custom ringtones are still very popular.
