Vivo NEX Dual Display Teardown

Vivo held a new product conference to launch its new flagship- the Vivo NEX Dual Display on December 11 last year. One of this full-screen smartphone’s highlights is its dual displays design. It has one display in the front and the other on the back. Today, we will explore its internal structure. Three months ago, we have dismantled Vivo NEX.

The phone boasts a 6.39-inch display with the resolution of 2340 pixels by 1080 pixels in the front, and its screen ratio reaches up to 91.6%. With such a full screen design, undoubtedly this phone will bring an impressive visual shock.

Besides, it features a 5.49-inch secondary display with the resolution of 1920 pixels by 1080 pixels on the back.

Teardown Summary
all the components
I find that the teardown process of the Vivo NEX Dual Display is the most difficult one`among all the phones I have torn down. It has a more complicated internal structure than that other phones adopt. Besides, its dual display design increases the difficulty of the teardown process. Therefore, we suggest that you’d better not tear down the NEX Dual Display yourself in case that you may destroy the internal structure of the phone.
