iQOO hasn't detailed the Z5x' specs sheet yet, but the poster it shared on Weibo reveals the smartphone's design. It has a rectangular camera island in the top-left corner housing a LED flash and two cameras, with the primary unit using a 50MP sensor.
The smartphone's right-side frame has a volume rocker and power key, which will double up as a fingerprint reader for biometric authentication.
There's another image on the event page set up on vivo's official website, which reveals the Z5x will pack a 5,000 mAh battery and have two color options. You can also see that the smartphone has a USB-C port at the bottom, flanked by a speaker and the 3.5mm headphone jack.
You can expect iQOO to reveal more about the Z5x in the days leading to the official unveiling next Wednesday.
