Smartphone cameras have made significant advancements, integrating features like periscope lenses, 200MP sensors, and all-pixel autofocus. Notably, one-inch camera sensors were introduced in 2022 with the Xiaomi 12s Ultra, sparking excitement about their potential. However, the uptake of this technology has diminished, leaving doubts about its presence in 2026.

Although some brands like HUAWEI continue to equip their Pro and Ultra models with one-inch sensors, others such as Vivo and Xiaomi have moved away from this feature in their newer releases. The Vivo X90 Pro and Xiaomi 13 Pro initially embraced the technology but later versions, like the Xiaomi 17 Pro Max, do not incorporate it. While one-inch sensors can still be found in some high-end smartphones, their overall availability is declining.
The main barriers to the widespread adoption of one-inch sensors include their size, which necessitates larger camera bumps on smartphones, leading to design compromises and ergonomic issues. Products like the Galaxy S25 Edge have shown that consumers are not favoring ultra-thin designs that sacrifice camera capabilities.
Moreover, the need for the sensor to sit farther from the lens for optimal focus contributes to design complexities. Companies like HUAWEI and Xiaomi have developed retractable lenses to tackle focusing issues, but this elevates hardware complexity and costs. Additionally, companies like Apple and Samsung prefer to maintain slimmer devices, finding it challenging to incorporate larger sensors without sacrificing essential features.
Telephoto cameras are also gaining prominence, pressing manufacturers to balance the sizes of their primary and zoom cameras. Alternatives to one-inch sensors are emerging, with brands like Vivo demonstrating that smaller sensors can match or exceed the capabilities of early one-inch models.
Despite these challenges, there are signs of renewed interest in one-inch sensors. The introduction of new one-inch sensors by manufacturers like Omnivision might encourage broader use. Sony anticipates continued growth in the adoption of large sensors, indicating that the trend could evolve positively toward the end of the decade.
While the Xiaomi 17 Ultra features a new one-inch sensor, it may not herald a universal return of this technology to flagship devices in 2026. Future smartphone cameras will likely continue to evolve, though one-inch sensors might not play as central a role as initially expected.
