The SM-J110H is the dual-SIM variant of the J1 Ace, powered by a Spreadtrum SC7727S SoC. Unlike high-end Samsung devices that use Snapdragon or Exynos chips, the Spreadtrum architecture has historically had less official documentation and kernel support, making custom ROM development more difficult.
Operating System: Originally launched with Android 4.4.4 "KitKat" and upgradable to 5.1.1 "Lollipop". Display: 4.3-inch Super AMOLED (480 x 800 resolution).
Connectivity: Limited to 3G networks (HSPA/WCDMA), lacking 4G LTE bands found in other J1 Ace variants. Popular "Exclusive" Custom ROMs
