Add more screen to your smartphone with the LG Smartphone Dual Screen Attachment. This optional accessory offers more display area by providing a second phone screen. The LG Smartphone Dual Screen Attachment doubles your display in no time. The attachment resembles a folio phone case that joins with the LG V50 ThinQ smartphone. Once you open it, the right hand inner cover provides an integrated display. Simply attach your phone by matching up the pins with the sensors. Similarly, one pin is used for communication while the other two are for power. Moreover, the hinge offers a complete 360-degree rotation, though it works optimally at 180 degrees or an obtuse angle. To turn on Dual Screen, just tap the icon that shows up once the attachment is connected. Thanks to its attachment system, adding the LG Smartphone Dual Screen Attachment to your phone is quick and easy.
