Xteink S4: Tiny Android eReader Debuts, But Is It Worth It?
10 Oct
Summary
- The Xteink S4 runs Android 11, allowing app access unlike other Xteink models.
- It offers direct access to Kindle and Kobo apps, a feature absent in rivals.
- Currently China-only, its global release and potential drawbacks are under scrutiny.

The Xteink S4 is positioned as a compact eReader, notably running Android 11, a feature absent in its predecessors like the X4 Pro, X4 Classic, and X3. This Android capability enables direct access to crucial reading applications such as Kindle and Kobo, addressing a long-standing limitation of other Xteink devices.
While the Xteink S4 promises enhanced app compatibility, its current availability is restricted to China. The device's operating system, Android 11, raises concerns about potential security vulnerabilities and may impact battery performance, a common trade-off with Android-powered devices compared to simpler Linux-based systems.
Compared to its siblings, the X3, X4 Classic, and X4 Pro, which rely on proprietary Linux systems and require manual book transfers, the S4 offers a more integrated digital reading experience. However, potential buyers must weigh the convenience of app access against the risks associated with an aging operating system and an uncertain global release.
