A couple friends of mine have smart phones from various companies (Galaxy S III's, iPhone 5's, Galaxy Note 2's) and they ALL swear by their Otterbox case/covers to having saved their phone from ridiculous drops/bumps/etc. I actually read a review of one for a Galaxy S II that claimed it survived a toss out the window at highway speeds - though I would hope most people aren't quite that clumsy with their phone ... but I digress.
Case in point (haha ... *ahem*), I went to the Otterbox website and they have covers for EVERY Samsung product EXCEPT the Galaxy Victory.
However, after having scoured the internet for protective cases for the Galaxy Victory LTE (and there are a few cases on Amazon that have gotten fairly good reviews and are pretty cheap), I happened upon the actual manufacturer a distributor of the Otterboxes who said that there is a case/cover (the "Defender" series) coming this week!
Here is the link if you're interested: http://www.thewirelessboysonline.com/samsung-galaxy-victory-otterbox-case.html
Once this case becomes available I'll buy it, try it out, and come back here with an update. Hopefully this will save another Galaxy Victory customer a little time and effort.
