Samsung Galaxy S7 is affected too.
On Samsung Galaxy S8 and S9 seems ok.

BrandonVR, do you mean it will make the audio *re*-sync? If not, then I don't understand what the workaround is.

A work around I found: It seems that playing the video for about a second (0.5 - 1 second) and then pausing it for about a second (0.5 - 1 second) will make the audio de-sync. The amount of time seems to matter which may be due to the Prepare command being poorly optimized on android.

Its not ideal to have this preparation time for every video, but if you do it off screen it may be workable.
