Not sure how this has good reviews. – Lucky Locky - Cool themes & Lock screen wallpapers Review

App crashes when trying to access camera permissions every time (and randomly for any other reason), the lock themes are all bad except for maybe one (but -- full disclosure -- I couldn't get them working anyway), and it doesn't even seem to change the wallpaper. Maybe I did something wrong, but there was no info presented for me within the app on how to fix that, so I'm going to assume it's just a money grab, since there are in-app purchases. Speaking of which, the app gives you 15 tokens to start, and each "theme" costs 10 tokens. None are free, but you're given enough for one (and a half).
