Oppo has come to Mobile World Congress this year not with a phone, but with a promise. That promise is a lossless 10x optical zoom that you'll be able to obtain from a new triple-lens cameraphone system the company just unveiled. I tried it out from myself, and while I wouldn't say that the results are quite as pristine as having a dedicated camera with a true optical zooming system, this is definitely the closest we've yet come to conquering the seemingly insurmountable challenge of injecting real zoom into the tight confines of a smartphone.
The key component to Oppo's system is a periscope setup inside the phone: light comes in through one lens, gets reflected by a mirror into an array of additional lenses, and then arrives at the image sensor, which sits perpendicular to the body of the phone. That's responsible for the telephoto lens in Oppo's array, which has a 35mm equivalence of 160mm. Between that lens, a regular wide-angle lens, and a superwide-angle that's 16mm-equivalent, you get the full 10x range that Oppo promises.
Oppo has confirmed that it's developing a smartphone camera system with a 10x zoom lens, as rumored. The tech is similar to the 5x zoom prototype the company showed off a couple of years ago, making use of the phone's lateral width to enable the necessary physical depth through the use of a periscope-style prism.
This time around the camera is 15.9-159mm-equivalent, meaning it'll start with an ultrawide perspective and zoom into medium telephoto. It's essentially three prime lenses in one, so Oppo's claim of "lossless" zoom might not quite be accurate throughout the entire zoom range, but it should be considerably [more] flexible nonetheless.
The system has optical image stabilization, but so far Oppo isn't saying anything about aperture, which has been the drawback of previous experiments with zoom lenses on phones. The Asus Zenfone Zoom, for example, had a 3x f/2.7-4.8 lens, and the results weren't great. Even the 2x f/2.4 "telephoto" lens on the iPhone XS turns in worse results than simply cropping the wider, faster primary camera except in the very best of lighting conditions.
The camera will be shown off at Mobile World Congress 2019 in February.

Chinese smartphone manufacturer Oppo has had an eventful time at the Mobile World Congress, Shanghai. The company became the world's first to introduce a new camera technology that will become mainstream in due course of time. Additionally, it also surprised everyone by launching an inter-device communication framework dubbed 'Meshtalk'.
[...] Oppo's MeshTalk is a first of its kind technology that's introduced by a smartphone manufacturer. Prior to MeshTalk, apps like FireChat allowed users to send each other messages and photos in the absence of traditional mediums of data exchange such as Cellular, WiFi and Bluetooth networks. MeshTalk, according to Oppo, will also allow users to make calls and send voice messages within a 3km radius in open fields. This radius can also be achieved in urban environments through a phone's relay claims the company.
Our early look at the technology suggests that it's nothing more than an application of the principles of wireless mesh modes to Oppo's smartphones. A Mesh network works by configuring a device to send and receive data packets from another device. For a smartphone, this means that a gadget's WiFi and Bluetooth radios can be configured to send and receive information from other similarly configured smartphones. The aforementioned FireChat app, for example, works according to these principles. However, Oppo claims that a 'custom chip' is behind MeshTalk, so maybe we're looking at a novel approach with the new technology.
