Cubot X100

GSMTechTok analysis

Who it's for

The X100 is for a budget buyer who wants a genuinely distinctive gimmick — a working secondary display built into the camera module — bundled with dependable everyday performance, and doesn't expect flagship polish at this price. Notebookcheck's aggregated scoring of Root Nation's review lands at a solid 82%, with the reviewer noting it delivers stable performance and handles everyday tasks efficiently without noticeable slowdowns. It's a strong fit for anyone upgrading from an older Cubot device specifically, since Root Nation's review describes it as reminiscent of the Cubot A40 but with meaningfully upgraded hardware and improved cameras. It's a weaker fit for anyone who cares about screen sharpness or low-light photography, since multiple independent reviews flag both as real, measured weak points rather than close calls.

Standout features

The secondary rear display is the phone's genuine differentiator — Root Nation's review found it a welcome, functional addition rather than a gimmick, letting users check notifications, control music, and preview rear-camera selfies without waking the main screen, while conserving battery by reducing how often the larger panel needs to light up. The 120Hz refresh rate on the main display earned real praise too: Root Nation found it makes a noticeable difference, with animations and scrolling feeling smooth despite the modest underlying resolution. Battery life held up well in real testing — unite4buy's review found the pairing of an efficient chipset and 5,100mAh cell delivers roughly 9-10 hours of active screen time, backed by 33W fast charging. The customizable smart button is a genuine, practical extra as well, supporting different actions for single, double, and long presses.

Trade-offs

Display resolution is the most consistently, bluntly criticized limitation — unite4buy's review is direct that the low HD+ resolution on a screen this large results in a mediocre, unsharp image, and Root Nation similarly notes the 260ppi density doesn't deliver particularly sharp detail even if daily use remains acceptable. Camera quality outside the main lens is a real, disclosed weak point too: unite4buy found the 5MP ultrawide and 2MP macro sensors practically useless, and the 64MP main sensor's lack of optical image stabilization means it struggles to deliver good detail in evening shots. Build materials are a genuine, comparative shortfall as well — unite4buy's review notes the widespread use of plastic instead of tempered glass or metal, plus a front camera design the reviewer calls a direct descendant of 2018. And unite4buy's broader assessment is candid that Cubot as a brand is increasingly lagging behind more successful Chinese manufacturers, a real, disclosed positioning caveat for the whole lineup rather than this phone specifically.
