The upcoming Vivo X300 Ultra could make its official debut sooner than expected. Since showcasing the device during Mobile World Congress 2026, Vivo has gradually revealed several details about its next flagship smartphone, hinting that the launch event is getting close.
While the company has not yet confirmed the exact unveiling date, a new leak from China suggests the flagship phone may arrive before the end of March.
Vivo X300 Ultra Possible Launch Date
According to recent reports from Chinese sources, Vivo could launch the X300 Ultra in China toward the end of the month. If the company follows its usual launch pattern, the device might debut on Monday, March 30, 2026.
Previous models such as the Vivo X200 Ultra and the Vivo X100 Ultra were also announced on Mondays, which makes the rumored March 30 date seem plausible. However, it’s important to note that this date has not been officially confirmed by Vivo.
If the timeline is accurate, the company is expected to reveal the official launch date very soon, especially as teaser campaigns for the device continue to appear online.
Camera System Already Revealed
So far, Vivo has already shared some details about the camera system that will power the X300 Ultra. The flagship smartphone will feature a triple-camera setup consisting of a main sensor, an ultra-wide camera, and a periscope telephoto lens.
There are also hints about an additional mysterious sensor, which could be designed to improve image processing and color accuracy. Vivo has not fully explained this component yet, but more information is expected before the official launch.
Only a Few Details Left to Reveal
With several key specifications already confirmed, only a handful of details remain unknown about the Vivo X300 Ultra. The company has yet to reveal the official pricing, full specifications, and market availability.
As Vivo continues to tease features of its upcoming flagship, more information should surface in the coming days, especially if the rumored late-March launch window proves accurate.
