Even though the vivo NEX 3 shapes up to be an innovative powerhouse with a waterfall curved screen and perhaps an under-display front-facing camera, the handset will also carry the beloved 3.5mm audio jack. vivo's product manager, Li Xiang, officially confirmed that the handset won't be ditching the legacy audio port - something even Samsung did with its latest Galaxy Note10+. We expect the device to be announced later this year and we can't wait to see what vivo has been cooking. Source (in Chinese)
