"The newest kakiyasu smartphone model, from low-cost provider Tone Mobile, is the Tone e20. Priced at a very reasonable 19,800 yen (US$180), it still boasts a perfectly acceptable list of features, with a 6.26-inch display, Android 9.0 operating system, 64 gigs of storage, and a triple-lens camera. It also comes with something called “Smartphone Protection,” but that’s not to protect the phone from damage, but a way by which the phone protects the user.

Smartphone Protection is an AI system that works with the Tone e20’s camera. After a photo is taken, Smartphone Protection analyzes the image and checks to see if it’s “inappropriate.” While Tone Mobile doesn’t say exactly where that line is drawn, it has announced that Smartphone Protection won’t allow you to take naked selfies. If you try to, you’ll get an error message saying that the photo cannot be taken, and the image data will be discarded without being saved."
