We're coming up to the weekend so what better time for a quick-fire, Android Central giveaway? This past week we looked at Olloclip's first non-Apple compatible lens system available now for the Samsung Galaxy S4 and Galaxy S5. Specifically we've got one for the Galaxy S5 and we're going to give it away to one of you!

Olloclip sells its 4-in-1 lens systems for $69.99 but you stand a chance of getting one for the grand total of free. How? Dead simple.

All you have to do is to log in with your Mobile Nations passport account and leave a comment on this blog post. That's it. We'll keep it open until 23:59 EDT on Sunday, October 12, then we'll select one lucky winner. Remember, this is specifically for the Galaxy S5, so if you've got any other phone you're not going to be able to use it. There's no restriction on location, either, so enter wherever in the world you are. Good luck!
