Extremely stuck when dragging rows on Android

We have used your latest react-native-sortable-listview, which works well on iOS, while really stuck on Android. More concretely, there are 3 points here (refer to the attached recording screens):
1) Stuck and slow when moving row in sortable listview;
2) Unexpected scrolling occurs when dragging the bottom row up;
3) Overlap of 2 rows is found when stuck.

We have tried everything we could but it is still stuck. Hope you could give advices and we do appreciate your help. Thanks.

Start by reproducing the issue on Android using the attached Recording screens.zip and the latest react-native-sortable-listview. Inspect the sortable list drag behavior while checking the three reported symptoms: sluggish movement, unexpected scrolling when dragging the bottom row upward, and overlapping rows. Done means row dragging is responsive without unexpected scrolling or overlap on Android, while the existing iOS behavior remains working.
