Does the S-View window work with the Galaxy A35 5G?

Yes. It is made for the A35 5G, so the window shows calls, alerts and the clock and the cutouts line up with the cameras and ports.

Can I wirelessly charge the phone with the case on?

The A35 5G does not support wireless charging, so this does not come up. You charge through the open USB-C cutout as usual.

How many cards fit in the wallet slot?

One card. The inside flap has a single slot, so it is for a transit or ID card rather than a full wallet.

Does it protect the screen?

The front flap covers the screen when closed and guards against scratches and light knocks. It is not a rugged case and offers little shock protection in a hard drop.

Is it bulky in a pocket?

It is slimmer than most folios, but the double-layer flap makes it thicker than a plain back cover, and the cover swings open when you hold the phone.
