+ Super speed, quality workmanship, very light, very good voice quality, etc. So long as the cell phone is not broken a great device. - I have this phone wrapped in silicone shell and glued a screen protector. It was in my front pocket, and I was only in the apartment. Nevertheless, it has a massive display damage. Have already read several times that the mobile phone is vulnerable. However, it said: Only KW 37-39 would be at risk. Mine is 4X. Diplay broken in half and therefore no longer usable.
