About Samsung Galaxy J4 2018
The Samsung Galaxy J4 2018 feels comfortable in the hand with its modest 5.49‑inch AM‑OLED screen, which delivers vivid colours and deep blacks despite its modest 720 by 1280 pixel resolution. Measuring 77.2 mm wide, 151.7 mm tall and just 8.1 mm thick, the phone slips easily into a pocket, while its 175‑gram weight gives it a solid yet lightweight feel. The single‑SIM layout keeps the design straightforward, focusing on essential connectivity without extra complexity.
Under the hood, the device runs Android 8.0 Oreo, providing a clean and up‑to‑date software experience right out of the box. Paired with 2 GB of RAM, it handles everyday tasks such as messaging, web browsing and light multitasking with reasonable smoothness. A 3000 mAh battery sits inside, aiming to keep the phone powered through a typical day of moderate use, while the compact dimensions ensure the battery fits neatly within the sleek chassis.
The SM‑J400G/DS model adds TD‑LTE connectivity tuned for APAC markets, a detail absent from the base model’s description. It also specifies 16 GB of internal storage, which the base model entry does not cover.
Compared with the other J4 2018 variants, this unit differs from the SM‑J400M/DS by using TD‑LTE instead of the LTE AM band, and from the SM‑J400F/DS Global TD‑LTE 16GB by being marketed for the APAC region rather than a global rollout. It shares the 16 GB capacity with that global variant but offers less storage than the SM‑J400F/DS Global TD‑LTE 32GB model.
