Sincerity compels me to admit that I did not fully comprehend; yet, what improved? My previous weapon was a twelve-sided pro. This one performs just as quickly, the screen isn't any better, the sound is the same, and neither the applications nor the operating system are dependent in any way on the phone. To tell you the truth, the island isn't very useful; it's more of a plaything than anything else. The cameras themselves do not take better pictures, but the shooting modes have been significantly improved. All of this does not even come close to covering the cost of one call made on the phone, and I was not charged for 13, but I was instantly charged for 14. Although the phone was not damaged in any way as a result of this, I do not recommend spending your money on this. By the way, quite bulky and weighty considering the size of my hand.
