Is still quite hard

I've imagined that the silicone shell is soft and prevents slipping of the mobile phone on smooth surfaces. It is quite hard on the left side of the "S" acting blue and soft at the point which seems darker. On the whole, the case fits harvorragend on my Xperia M dual.
The mobile phone becomes much grip and is comfortable in the hand. The keys are easy to press.
I have it. In combination with a white cell phone Looks good.

Small hooks: Thicker jack can not be introduced deep enough. The shell interferes. With earphone cable is but no problem!
