One of my videos that's over a year old is suddenly being featured by the youtube algorithm, but almost entirely on Android phones.

iOs views are increasing, but considering iOs vs Android is basically an evenish split worldwide, I'm very confused as to why 75% of my views in the last few days are Android only, whereas historically it's been mostly windows.

This pic shows the Android surge over last week

43441,


and this pic views by source shows the surge is algo driven traffic.

43442

Any ideas why this video is being featured on Android almost exclusively?

Other stats are normal(ish) - most viewers US, but other nations share growing each day,
