Key specs
Critic reviews
No Compass Score yet. We calculate one once enough reviews include a score.
“BLU has an excellent smartphone in the BLU S1, and perhaps the “S” will stand for “stellar” after another iteration or two. BLU needs to fix a few essentials and perhaps even bump up the future S2’s price to accommodate fast charging and USB Type-C charging, and the BLU S series will be hard to beat.”
