S4 camera failure and then sim card not recognised

[ACT02]

OK I get a camera failure warning on the SG S4. I have done:

* Settings -> More -> Application manager -> All -> Force stop, Camera Clear cache and Clear data, restart
* Wiped the cache partition. Restart
* Factory reset
* On the PC via usb cable, went to folder: Computer\SAMSUNG-SGH-I747\Phone\Android\data\com.sec.android.gallery3d\cache and deleted everything in this folder.
* Then looked for : Computer\SAMSUNG-SGH-I747\Phone\Applidium Image Cache, could not find it.
* removed battery for several hours, restart.

These have not worked. What next?

Also sim card is not recognised. Tried my sim card in another phone, i was OK. Tried another good sim card in my phone, it did not work.

so it's broke or just throw it in the too-hard-bin and get a new phone?

Please throw us a bone here. I posted the question here because I was hoping to get an informed response. The only reply so far may be informed but looks like much like an answer I'd get if I had asked the same question on facebook.

Is it a hardware issue? Is the phone broken? Is it a software issue? A firmware reflash? Is there a diagnostic process or guideline I can follow?
