Background and related features
Google previously mentioned Left-Behind Reminders in its October Play Services update changelog, according to Android Authority and SammyGuru. Jetstream said the feature was initially previewed and prepared as “Left-Behind Reminders” in the October 2026 “Google System Release Notes,” with the description “You’ll get a notification when this tag leaves your phone,” and that it supports configuring “Excepted locations.”
Google has also updated the registration flow for Find Hub network tags, allowing users to set up Left-Behind Reminders during initial configuration, according to SammyGuru. Android Authority reported that Google is expected to introduce NFC support that lets users quickly identify lost tags by tapping them with their phone.
Competitors have offered similar capabilities for some time. Apple has had separation alerts for years for Find My-enabled tracking devices, and Samsung added the feature to SmartThings for devices such as Galaxy SmartTags and Buds a few years ago, according to Engadget. SammyGuru noted that Samsung Find’s “Notify when left behind” feature alerts users when the connection between a phone and an item breaks and supports Safe Places.
