Questions about this item

How well does the 10.9 inch case hold up to daily drops and impacts?

The hard-shell back and flexible TPU bumper absorb shocks from drops, while the soft microfiber interior prevents scratches on the tablet surface.

Does the auto wake/sleep magnet drain the Galaxy Tab S9 FE battery when the lid stays closed all day?

The built-in magnets only trigger the sensor when the cover opens or closes, so there is no continuous power draw while the lid remains shut.

Which S Pen models fit the built-in holder on the SM-X400/X406B case?

The holder is sized for the Samsung S Pen that ships with the compatible Galaxy Tab S10 Lite, S10 FE, S9 FE and S9 11 inch tablets.
