Compatible Galaxy Tab models

This keyboard folio case fits the Galaxy Tab S10 Lite 5G 10.9 inch (SM-X400/X406B) 2025, Galaxy Tab S10 FE 5G 10.9 inch (SM-X520/X526B/X528U) 2025 and Galaxy Tab S9 11 inch (SM-X710/X716B/X718U) 2023. It is designed for users who want a protective cover with integrated input devices for these specific tablets.

Magnetic attachment and angle adjustment

The case uses a magnetic keyboard that attaches to the tablet and offers three viewing angles via anti-slip grooves. Installation requires aligning the tablet with the magnetic strip and sliding it along the front-to-back axis to lock into a groove; misalignment can prevent a secure hold or keyboard connection.

Model-number verification

The single specification that decides fit is the exact tablet model number printed on the back of the device — only SM-X400, X406B, X520, X526B, X528U, X710, X716B or X718U are supported; other 10.9 or 11 inch Galaxy Tabs will not work with this folio.
