According to a document that appeared online recently,
ZTE has been granted a new patent from the CNIPA for a smartphone with dual punch hole selfie cameras. The patent sketches show that there are two openings in the middle of the top of the phone screen.
Actually, there is no big deal in this dual punch-hole camera design because recent exposures from Oppo and Xiaomi seems to have gone past this level. Yesterday,
Oppo showcased a video of a smartphone which has an "invisible" selfie camera. Interestingly, a few minutes after Oppo's video appeared online,
Xiaomi released its own video with a similar front camera solution. Thus, it appears that we are now in the era where there won't be any physical evidence of a front camera on the screen but its there.
