Edit: Thought about getting the $50 version, but I'm not quite that frugal.
Second Edit: You probably need NFC for this huh? Drat.
Wow. Not a comment about you in particular, but about the industry in general. I did a quick search and found this: http://bluproducts.com/android-phones
Really? 66 different phones? Is this entire industry, except for Apple, run by imbeciles? Not that I'm in the target demographic, but I only have a relatively few years left on this earth. I don't want to spend half of them just figuring out the differences between Android phones!
Hasn't the rest of the world learned anything from St. Steven?
Out of curiosity, I went to find out how many variants Apple is currently selling[1] (model, color, storage). I counted 42 distinct combinations you could possibly choose! I guess not even Apple learned from 'St. Steven', or he was wrong.
Removing the color axis whittles down the model/memory combination to a more manageable 12 options - but the point remains.
BLU is a usually-cheap phone brand, with handsets starting around 60USD.
The magnet isn't damaging the phone — at least not at field strengths likely to be encountered in everyday life. Removing the magnetic field should immediately turn the screen back on.
