Questions about Samsung Wallet Cover

Can the smartphone be charged with the cover via Qi?

Is there actually a guide to the cover, I suspect I haven't discovered everything that goes with it and how.

I charged my phone with the wireless charger and since then the magnet in the case that is supposed to activate the phone when it is opened no longer works. I have already tried it with the cover of a colleague who has the same cover and it still works with his cover. What can I do?

On my Galaxy S20 FE, the display does not switch on and off when I open or close the cover. Do I have to make any settings on the smartphone? Or is the cover defective?

Which Wallet Cover fits the Samsung Galaxy S20 EE EU? I'm not sure if I've chosen the right one with the Samsung Wallet Cover Galaxy S20 FE. The wallet belongs to the blue colour group, but the smartphone belongs to grey.

Do I need an armoured glass film if I use this protective cover and does the cover then also close with the armoured glass film?

When opening this cover, does the display switch on and off when closing it?

Will the blue variant be available soon ?
