Re: Replacement LCD and screen?
The Galaxy S7 Active does not have an LCD - it's a Super AMOLED panel. Yes we understand what you're talking about but even so, being accurate with the technology and the hardware would probably help you along the way.
The Galaxy S7 Active has only been on the market since June so they're all basically about 4 months old and Samsung offers a 1 year parts/labor guarantee: the only reason you might not be able to get warranty service would either be you got it someplace you can't use as proof of purchase (craigslist/etc) or you can't make the claim because you did actually break it yourself and it wasn't accidental.
Anyway, there don't appear to be any GS7A parts available at this time, it could be a few more months before they become available on eBay, eTradeSupply, and other websites that specialize in such hardware. If it's damaged you don't have much choice in the matter except either wait for the parts to become available or contact Samsung and pay what they ask (I think it's like $270+ to replace the Super AMOLED panel as a repair job).
