China-only · no intl release planned
Xteink S4
The Android pivot — sideload Kindle, Kobo, anything.
Xteink's first Android model: sideload Kindle, Kobo, or any reading app, plus its first front light. Sold in China only, and Joshua Lowcock's tracker shows no international release planned as of August 2026, so importing is the only route.
