Apple's iPhone Duo Debut Drives 300% Spike In Samsung Galaxy Z Fold8 SearchesFrom Kaleido 3 To Kaleido 4: What's ChangingIf you've used a color e-reader from Boox, Kobo or PocketBook, you'll have seen an earlier E Ink model, called Kaleido 3. The Amazon Colorsoft, recently updated to its second-gen model, also uses Kaleido 3, but in a customized version designed to improve performance. The new release is Kaleido 4 and aims to address color reproduction and contrast issues, not to mention the speed of page refreshes. "Compared to the previous generation, E Ink Kaleido 4 doubles its color gamut volume to more than 40K, increases white reflectance by 15%, and improves contrast by 50%," the maker of the screen announced. "Additionally, with the introduction of new algorithms, E Ink Kaleido 4 is capable of video playback at up to 18 frames per second (FPS).

The e-paper industry is undergoing a pivotal transition from black-and-white to color. On October 15, at the 2026 Second E-Paper Ecosystem and Industry Integration Innovation Development Forum, E Ink Holdings and Hanwang Technology jointly unveiled the next-generation color e-paper technology E Ink Kaleido 4, alongside the world's first end product powered by it—the Hanwang M10C Gen 2 color e-paper office tablet. The move marks a substantive breakthrough in core metrics such as color performance, refresh speed, and dynamic display, as e-paper devices extend their target use cases from simple digital reading toward professional office work and information-intensive tasks. E Ink Holdings Chairman Li Zhenghao said at the launch that color e-paper continues to evolve toward richer, more natural color rendering, with E Ink Kaleido 4 delivering improvements in color performance, brightness, contrast, and dynamic display capability while preserving a paper-like reading experience.

Oppo’s Reno17 series could launch in China as soon as November with a 200MP rear camera, according to GSMArena, but the other leaks published the same day disagree on almost everything except the timing. One says the lineup has no Pro model and uses three 50MP cameras, another describes two models with a 200MP sensor, and a third puts a different chip inside, so the only detail that looks settled is that a new Reno is coming roughly six months after the Reno16. For buyers who picked up a Reno16 this summer, that schedule matters more than any single spec. The 200MP figure is also less new than it sounds. Oppo already used a 200MP f/1.8 main camera on the Reno16 Pro, which launched in China in May alongside three 50MP cameras, a 7,000mAh battery and a Dimensity 9500s chip, according to Notebookcheck. The open question is therefore not whether Oppo can ship a 200MP Reno, but whether that sensor moves down to the standard Reno17 or stays on a Pro that one leak says may not exist. What Do the Reno17 Leaks Actually Claim?
