We have discussed in a detailed post why 8K video recording is pointless on smartphones right now, and possibly the only reason why companies like Samsung retained the feature in its Galaxy S21 series was to obtain bragging rights. It is a feature that still requires tweaking even on the latest hardware, which could be one reason why the Galaxy Z Fold 3 may not support it.

Samsung is expected to unveil two new foldable smartphones, the Galaxy Z Fold 3 and the Galaxy Z Flip 3 on August 11. While we will know what to expect during the official announcement, there will continue to be tidbits on the internet floating around, talking about what features will make their way to the newer devices. One person, Roland Quandt, mentions on Twitter that the Galaxy Z Fold 3, despite its ludicrously high price tag, will not support 8K video recording.
