Smart 4 Plus

The Lava Smart 4 Plus runs Android 15 and uses a 6.75-inch IPS LCD with a 20:9 aspect ratio and 90 Hz refresh rate. Its resolution is 720 × 1,600 pixels, with 260 ppi and a documented peak brightness of 90 nits. The specification therefore establishes a large panel with a higher refresh rate, while also showing modest pixel density and brightness figures. No hands-on testing is available to support conclusions beyond those measurements.

Its hardware is built around the Unisoc SC9863A octa-core processor, 4 GB of RAM and up to 64 GB of storage, with expandable storage supported. The Li-Ion battery is rated at 5,000 mAh and supports 10 W fast charging; the listed specifications also include 10 W wireless charging. A 13 MP rear camera records 1080p video at 30 fps and has an LED flash. The front camera is 5 MP.

Connectivity covers Dual Nano-SIM, GSM/HSPA/LTE, Wi‑Fi 4 and Wi‑Fi 5, GPS, GLONASS, USB Type-C, USB OTG, a 3.5 mm audio jack, FM radio and stereo speakers. The fingerprint sensor is mounted on the side. IP64 resistance, 165 × 76.1 × 8.5 mm dimensions and Blue or Silver body colours complete the documented package. It suits users who want Android 15, a large display, a high-capacity battery, dual-SIM support and practical wired connections. Bluetooth 4.2, USB 2.0, the 28 nm process and 10 W charging are the main specification trade-offs to keep in view.
