At the phone, it is fluid, and well navigates from one application to another. The only weak point that I find him is that its battery when using applications and internet, only lasts a day and takes time to recharge (so recharge it overnight;)). The camera is not great when you're shooting in a little dark. In terms of complementary, the cover is very good, and protects the screen. The headphones, for against, are small bill so the sound is not at the top, but again, for the price it is awesome.
Especially that the phone is low wave emissions.
I really recommend if you do not want to ruin you but have a smartphone anyway;)
