3rd party samsung s view covers does work with the latest update ! & samsung was not lying from the very beginning.
So your phone is on & you fixed the fake/third party cover & it works, but after reboot it stops funtioning right ?
Here is how you fix it. All you have to do to get it working again is to flip your s view cover to the back or leave it dangling, then either do a reboot or power off, next when you on your phone make sure your s view cover is still to the back or still dangling, only once you have passed the samsung boot animation & you are at the unlock, insert password or input patern screen wait another 10 seconds, now when you close the cover back it will 1000% work ! something in the boot process turns off the fake s view cover. please try and tell me if it works or not.
