About Wiko Sunny 4
The Wiko Sunny 4 presents a compact handset with a 5‑inch colour TN‑TFT LCD screen that delivers a resolution of 480 by 854 pixels. Its overall footprint measures 73.5 mm wide, 146 mm tall and 8.7 mm thick, while the device tips the scales at 160 grams, making it light enough to slip into the palm. The chassis is built to accommodate a single SIM card, keeping the layout straightforward for everyday use.
Under the hood the phone runs Google Android 8.1 Oreo in the Go edition, a streamlined version of the OS aimed at modest hardware. It is paired with 1 GiB of RAM, which together with the entry‑level processor supports basic apps and tasks. Power comes from a 2200 mAh battery, offering enough endurance for typical daily usage without needing frequent recharging.
The Wiko Sunny 4 Dual SIM 16GB M2850 upgrades the base model by adding a second SIM slot, allowing two numbers to be used simultaneously while retaining the same physical design. It also provides 16 GB of built‑in storage for apps, media and files.
Compared with the other dual‑SIMSunny 4 variant (M2771) that ships with 32 GB, this model offers half the internal capacity, making it a more economical choice for users with lighter storage needs.
