Vivo launched the V15 Pro mid-ranger just a week ago, however, the company is ready to announce another mid-ranger, this time for the X-series. Compared to the V15 Pro, the upcoming X27 would get a few upgrades like the 8 GB of RAM, a slightly better 13 MP wide angle camera on the back, and a bigger 3,920 mAh battery, but would also feature a slightly slower Snapdragon 710 SoC and only a 16 MP selfie cam.
