Xteink S4 e-reader switches to Android 11, doubles battery capacity

Chinese startup Xteink is following up its compact X4 e-reader with the Xteink S4, a 4.3-inch E-Ink device that ditches the previous proprietary Linux OS for Android 11. This change lets users sideload apps like Kindle, Kobo, and KOReader instead of being limited to DRM-free EPUB files. The S4 also bumps up specs with 2GB RAM, 32GB storage, and a 1,400mAh battery, more than double the X4's 650mAh cell.
