RIM BlackBerry KEYone BBB100-5 Dual SIM TD-LTE CN 64GB (TCL Mercury)

The BlackBerry KEYone carries a compact, pocket‑friendly footprint at just under 9.5 mm thick and a weight of 180 g, making it easy to handle despite its solid build. Its 4.48‑inch IPS TFT LCD panel delivers a sharp 1080 × 1620 pixel resolution, offering crisp detail and vivid colours in a size that feels comfortable for one‑handed use. The device’s physical keyboard, a hallmark of the KEYone line, sits beneath the screen, giving the handset a distinctive look while adding a tactile typing experience that sets it apart from most Android phones.

Running Android 7.1.1 Nougat, the phone is powered by 3 GB of RAM and a 32 GB internal storage compartment, providing enough headroom for everyday multitasking and app usage. A 3505 mAh battery sits behind the rear panel, promising solid endurance for a full day of moderate use. The single‑SIM slot, combined with the modest dimensions of 72.39 × 149.10 × 9.40 mm, keeps the KEYone streamlined for users who prefer a straightforward connectivity setup without the bulk of dual‑SIM arrangements.
