The noblest shell that I have ever seen in a mobile phone. I was pleasantly surprised about the fact that the key lock is automatically activated when the lid snaps shut. Also, opening the phone will automatically recognize. Everything is stuck, nothing wobbles. Also the lens cap fits perfectly and protects against dust and scratches (the cover is strongly recommended, after 10 months without a lid was the camera function because of dust behind the glass cover unusable and had to be completely replaced)
