According to the benchmark database, the V21 SE, bearing model code V2061, runs Android 11 (likely with FuntouchOS on top) and has 8GB RAM onboard. There could be a 6GB RAM option as well, but that's yet to be confirmed.
The motherboard section of the listing mentions "atoll", which is a codename for the Snapdragon 720G.
Previously, the V21 SE was spotted on Google Play Console with the same specs. Additionally, Play Console also revealed that the smartphone will pack a notched display having 1080p resolution and pixel density of 440 ppi.
The rest of the V21 SE's specs are still a mystery right now, but we'll surely learn more about the smartphone in the coming weeks.
