BLU's camera app has some cool tricks.

BLU has some good camera functions that you might like, as I've mentioned before.
Instead of making a camera that tried to "wow" photographers (which doesn't even happen amongst the iPeople - not in real life, anyway),  the Vivo 8 has added OCR and edge detection tricks for taking photos of business cards, forms, or translating text from one language to another.
This isn't anything you can't get elsewhere by installing Google's Keep, Photo Scan, or Translate, but it's nice to see BLU taking the extra step of adding some functionality...
