Problems I encountered while automating on Android device

I am doing automation on Droid X (Android).
I have encountered the following problems. Could you please give me some help?

  1. When scrolling down and up, there is a chance some text will be selected. This blocks further scrolling.
  2. When scrolling, there is a chance no scrolling is performed.
  3. When removing or typing some text in a text field, there is a chance the initial tap on the text field is not valid, causing no text to be removed or entered.
  4. When tapping on an icon, there is a chance that the tapped icon has response but does not perform its action.
  5. Latency issue. Eggplant keeps loading when device has already done.
