Signal's latest beta release introduces the ability to link an Android phone or tablet to an existing account as a secondary device, closing a long-standing gap in the encrypted messaging app's multi-device story. The site AboutSignal first reported the feature in testing, and Signal has since updated its official support documentation with instructions for linking Android phones and tablets as secondary devices (Engadget).

Until this beta, Signal's linked-device architecture allowed only iPads and computers to act as secondary devices paired to a primary phone. An Android phone or Android tablet could serve as the primary device but could not itself be linked as a companion to another account. That left users who wanted Signal on, say, both a personal phone and a work phone, or on a phone and an Android tablet, without a native solution. The new beta removes that constraint for the Android ecosystem.

Signal has also designed a split-screen tablet interface optimized for larger displays, with a chat list panel on the left and a conversation panel on the right, according to findings reported by AboutSignal and surfaced via Engadget. This layout mirrors the two-pane design common to desktop-class messaging clients and to Signal's own iPad experience, and it signals attention to the tablet form factor beyond simply scaling up the phone UI.

The feature remains in beta, and Signal has not announced when it will exit beta and reach general availability. The rollout also appears to be in early stages: an issue filed on Signal's Android GitHub repository in March 2026 (issue #14680) reports that a Samsung Galaxy Tab S8 could not be linked as a secondary device, with the user seeing only the phone number entry screen upon launching the app (GitHub). That report predates the current beta coverage, but the symptoms it describes, a device that does not present the linking flow, are consistent with a feature still being staged across builds.

There is also a documentation lag worth noting. Signal's official troubleshooting page for multiple devices still lists only iPads and computers as "currently supported linked secondary devices" as of the time of the beta rollout (Signal Support). The linked-devices support page, by contrast, has been updated with Android-specific instructions (Signal Support). The mismatch is not unusual during a beta, but it does mean users consulting troubleshooting docs may not yet see Android secondary devices reflected as supported.

Signal's multi-device architecture uses a companion-device linking model rather than full account-based multi-login. A primary device holds the keys and the registration; linked devices receive copies of the message history and synchronize going forward, but they do not function as independent logins to the same account. Adding Android phones and tablets as secondary devices extends that model rather than replacing it. For users already familiar with linking a desktop or iPad, the Android secondary flow will be procedurally similar: the primary device generates a QR code, and the secondary device scans it to establish the link.

The practical appeal here is straightforward. A user who carries an Android phone and an Android tablet, or who maintains a secondary phone for work or travel, can now keep Signal synchronized across both without routing messages through a single primary device. For a privacy-focused messenger whose users often select it specifically to avoid cross-device metadata exposure, the ability to keep conversations on a second Android device without re-registering a phone number is a meaningful convenience gain.

Whether the feature reaches stable quickly and whether the GitHub-reported linking failures are fully resolved will determine how much this changes day-to-day use. For now, it is a beta worth testing for anyone whose Signal usage spans more than one Android device.
