Vivo NEX Dual Display Teardown

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

Teardown Summary

I found the teardown process of the Vivo NEX Dual Display to be the most difficult of all the phones I’ve ever disassembled. Its internal structure is more complex than that adopted by other phones. In addition, its dual-display design increases the difficulty of the teardown process. Therefore, we suggest you’d better not tear down the NEX Dual Display yourself in case you destroy the internal structure of the phone.
