It looks like the race is on. After Xiaomi’s code was torn apart recently, suggesting that they’re working on a phone capable of shooting 8K 30fps video, it looks like Samsung’s S11 may be capable of the same. The team at XDA Developers, the same team that delved into the Xiaomi, has found hints that the S11 will bring 8K video after looking at the latest Samsung Camera App (presumably one that fixes this problem, too).
They do stress that just because evidence may exist in an Android Package (APK) file does not mean that it will necessarily come, as these features are currently unimplemented and may be pulled at any point in the future. But that it’s appeared now in two major competing manufacturers smartphones does seem to suggest that it’s on the way at some point.
