Dunno theres a buggy model out there, all s4 models are good to go
no masla
i got mine from hafeez center.. just get it from a shop and check it properly before buying i'd recommend MULLER AND PHIPPS warranty one.. the teletec ones packaging didn't look good to me and the fact that they paste the battery outside the BOX looks so cheap man
price cut LOL well dunno but its been almost 2 months since its out so there might be one but u never know until it happens haha...
i got it from the shops opposite pace in hafeez centre on the ground floor ( not basement )
