Common questions
Does a case block the Xteink X4's back magnet?
Magnetic snap-on cases are designed to leave the back magnet fully exposed. Slim polycarbonate shells that cover the back may partially reduce pull strength. Leather sleeves are removed before mounting so they don't interact with the magnet.
Are X3 and X4 cases interchangeable?
No. The X4 and X3 have different dimensions. Always check that the listing specifies your model.
