Some company can make money!

Fabricate an aluminum back for the Galaxy S4. Figure out how to put a plastic spacer aka HTC One in the back for antenna reception. Could sell a TON.

Update: My bad for not checking first, but a lot of people are making metal backs for the S4, but I don't see any that can accomodate the antenna reception or NFC.

There are already metal backs for the S3 and Note 2. Only a matter of time until they start selling one for the S4.

They alreay sell a metal back for the S4. Not sure if they do anything to make sure reception and NFC still works properly.
