Niantic uses Pokémon Go player data to build AI navigation system

Last week, Niantic announced plans to create an AI model for navigating the physical world using scans collected from players of its mobile games, such as Pokémon Go, and from users of its Scaniverse app, reports 404 Media.

All AI models require training data. So far, companies have collected data from websites, YouTube videos, books, audio sources, and more, but this is perhaps the first we’ve heard of AI training data collected through a mobile gaming app.

“Over the past five years, Niantic has focused on building our Visual Positioning System (VPS), which uses a single image from a phone to determine its position and orientation using a 3D map built from people scanning interesting locations in our games and Scaniverse,” Niantic wrote in a company blog post.

The company calls its creation a “large geospatial model” (LGM), drawing parallels to large language models (LLMs) like the kind that power ChatGPT. Whereas language models process text, Niantic’s model will process physical spaces using geolocated images collected through its apps.

The scale of Niantic’s data collection reveals the company’s sizable presence in the AR space. The model draws from over 10 million scanned locations worldwide, with users capturing roughly 1 million new scans weekly through Pokémon Go and Scaniverse. These scans come from a pedestrian perspective, capturing areas inaccessible to cars and street-view cameras.

First-person scans

The company reports it has trained more than 50 million neural networks, each representing a specific location or viewing angle. These networks compress thousands of mapping images into digital representations of physical spaces. Together, they contain over 150 trillion parameters—adjustable values that help the networks recognize and understand locations. Multiple networks can contribute to mapping a single location, and Niantic plans to combine its knowledge into one comprehensive model that can understand any location, even from unfamiliar angles.

Samsung quits updating Galaxy Z Fold 2 that came out in 2020 for $2,000

In February 2022, Samsung started promising up to four generations of Android OS and One UI upgrades to “select” Galaxy devices, as well as “up to five years of security updates.” And in January, it announced moving to seven years of security and OS updates, matching a move from Google. However, the Fold 2 wasn’t included in Samsung’s list of “select” Galaxy devices.

Thus, one could have estimated that the Fold 2 might stop receiving OS and security updates by 2024, four years after its debut. But it’s still hard to reconcile with paying four figures for a phone that became a security risk after four years, despite functioning properly otherwise. Apple, by comparison, now promises at least five years of security updates. Apple only started making that promise in 2023 with the iPhone 15 series. However, the current-generation iOS 18 is supported by iPhones released in 2020, like the second-generation iPhone SE, and even older ones, like the iPhone XR that came out in 2018. Arguably short-lived expensive devices like the Fold 2 are part of the reason some activists are pushing for the FTC to require that smart devices state on their packaging how long they’ll receive updates.

However, unlike iPhones, Samsung phones aren’t all powered by a proprietary chip, making promises of upgrades require commitments from third-party vendors, like Qualcomm. With Qualcomm known for being resistant to longer chip life cycles in the past, seven years of updates is progress for Samsung users—just not those who invested in the Z Fold 2.

Faulty Samsung update leaves owners of bricked Galaxy phones with few options

Samsung issued a software update on October 2 that bricked some older Galaxy smartphones. While Samsung has stopped the update from rolling out further, those with broken phones have received a harsh reminder of the importance of data backups.

On Wednesday, numerous people online started complaining about their Samsung phones being stuck in a bootloop (you can see examples here, here, and in newer comments here).

A Samsung spokesperson confirmed to Ars Technica that an update to Samsung’s SmartThings Framework app for managing smart devices caused the problems:

We are aware that a limited number of Galaxy smartphones running on Android 12 are rebooting continuously during an update to the latest version of the SmartThings app.

Samsung “immediately suspended the update” after learning of the problem and is “working to resolve the issues,” the company’s spokesperson said. According to user reports online, Samsung has issued a new update that people can download without their phones breaking.

However, owners of older affected phones, namely the Galaxy S10 series, Galaxy Note 10 series, Galaxy M51, and Galaxy A90, have been unable to power their devices on to roll back the update. Many users who already manually or automatically installed the update are still dealing with bricked devices.

A harsh reminder

Users with bricked Galaxy phones were initially met with a difficult choice: Go without their phone or perform a data-erasing factory reset.

Samsung’s statement to Ars advised customers to “contact the Samsung Contact Center” for support, but it’s unclear if a fix can be employed that doesn’t wipe the phone.
