A:AnswerHi there Isabelle, thanks for taking the time out of your day to ask us your question about the Samsung Galaxy Tab A9+. The Galaxy Tab A9+ offers expandable storage capability, up to 1TB, when you add a microSD card to this device. Feel free to contact Support if you think of any other questions for us. Thank you for being a faithful Samsung customer. - Debra
A:AnswerThe Tab A9+ does not natively support Power over Ethernet (PoE). So a true PoE injector won’t work directly unless paired with a specialized adapter check out LAVA products.

Some users report success using multi-function USB-C hubs with Ethernet and PD passthrough, but compatibility can vary. Look for hubs that explicitly mention Android or Samsung tablet support.
