Hello. Really liked the phone, but disaster struck, he fell off the couch and cracked screen (height 40 cm), tempered glass as far as I know. This could happen if the glass is not tempered or defective. Video filming your company, and I doubt very much that the screen was crashed from 40cm height if he withstands nails. Talking with the seller, offered to buy. If you want to I can show photo of the phone and accident place (phone is now in active use, and despite the broken screen sensor works fine). I want to replace the screen under warranty, I believe that was disrupted production technology.
