Source: https://pocketink.io/

PocketInk is the independent, owner-tested how-to hub for Xteink pocket e-readers. The X3 is the button-only model you can buy; the X4 Pro is the front-lit step-up; the original X4 is discontinued; the S4 is China-only. Guides cover buying, first-week setup, book transfer, custom firmware, accessories, and screen repair. Not affiliated with Xteink.
