so i was working on my d4 as normal and the screen wouldnt wake up via the power button, would work via sliding keyboard. called verizon and replacement on the way but continued to use my d4... well the screen started going dim while using it and then it started smoking... well the ribbon cable between the two halves was sparking and now has daylight when opened just right. Phone now no longer powers up but hey i have a replacement coming tomorrow. just a heads up for any heavy texters that sliding the keyboard out alot will cause this.
