I immediately protected by a rubber shell Ringke FUSION bought on Amazon.
Well the first drop, the screen is completely cracked, he answered at all, the phone was unusable.
I contacted customer service SONY MOBILE, who has wanted to make no commercial gesture.
I have a bill of 125 euros to change my phone's screen, with no guarantee that this fragility is not recurrent.
Discussion forums widely expose the fragility of the screen problem.
I do not recommend this product for the extreme fragility of the screen, and contemptuous policy of SAV SONY.
