4inch Smartphone

The 4-inch smartphone segment has transitioned into a "micro-niche" market in 2026, primarily served by specialized Chinese manufacturers like Unihertz, SOYES, and ONEMYTH. While mass-market "compact" flagships have settled around 6 inches, a fiercely loyal user base continues to drive demand for true one-handed devices. AlibabaReddit
