Replace another phone look good

First of all, this phone does not come with Firefox OS, despite all other reviews. It came with a deformed case. It is not possible to mute the boot sound. Moreover, for some reason, wifi MAC address keeps changing which makes it impossible to use on networks that require MAC registration.

so far it behaves excellent.
