As Samsung gets ready to launch its Galaxy Z Fold 3 and Flip 3 range, likely sporting under-display cameras, everyone else is showing off their under-display camera tech hoping to get all the nice halo effects of the tech.

• The short recap is ZTE was first to market with an under-display Axon 20, which was bad and more a technical demonstration for the market to see.
• ZTE’s now at second-gen tech with the Axon 30, which launched on July 27, though we haven’t seen reviews yet.

Now, Oppo and Xiaomi are trying to muscle in, with the game of me-too being playing out:

• We’ve seen this game plan before. Ahead of the first Fold release, Oppo and Xiaomi showed off their own folding tech, and then did nothing for years, until Xiaomi brought something to market. (Oppo went for rollable over foldable).
• We’re at a similar stage: ahead of the biggest company in Android making noise in one week, Oppo and Xiaomi are trying to get in first.
• First, Xiaomi, which will launch the Xiaomi Mi Mix 4 on August 10. Details discovered in MIUI 13 code suggests a flagship with an under-display camera is coming soon. A “leaked” Mi Mix 4 video shows a pretty crazy, super flexible screen, with under-display camera as well — and it’ll probably not be anything like the final product.
• And from Oppo, there’s a more official unveiling of its “next-generation under-screen camera technology,” including a helpful sample photo and a bunch of tech insights.
• Those include: shrinking the size of the pixels on the display without reducing the number of actual pixels, meaning enough of a gap for sufficient light to hit the camera, while retaining a 400 PPI display. 
• There’s also a swap from traditional screen wiring for thinner, transparent wiring, for “much finer display quality,” and further tweaks for the area directly above the camera.
• So, that’s a lot of promises. The sample image looks like this:

• Which is decent, in broad daylight, though clearly worse than a normal selfie cam, and you’ll spot lens flare. Low-light will be a further test.
• But who knows when Oppo’s tech it coming. It first talked about this in 2019, and it said it’s still working on the hardware and algorithms now.
• We don’t expect a new Oppo flagship (X4 Pro?) until 2022, so …maybe then?
• Meanwhile, Xiaomi and Samsung will show off their tech next week.

An Airbnb for swimming pools is here, and it’s called Swimply.

• It’s pretty simple: monetize swimming pools and give people access to more pools — and there are some 13,000 pools on the app across North America and Australia. Maybe elsewhere, but none in Germany yet.
• CNET took it all for a ride and said it was less weird than you think, and somewhat economical: “At $20 an hour, it was less expensive than full-sized pools in the area, which can cost more than $100 an hour to rent. The average rental cost for a Swimply pool in the US is about $40 to $45 an hour.”
• That said, pools feel like one standalone thing you need a few extras with. People need bathrooms, easy access, chairs, pool toys, water, etc., and that seems to be an issue at times for some pools — owners can be home and might not want a bunch of soaked people in the house, which is more Airbnb style. And let’s not talk about insurances…
• I don’t know, it makes sense for some people, and people with backyard pools and such, I guess? It does feel a little bit like everything has to be monetized, butttt that’s late-stage capitalism…
