Targeting Android 2.2
I have read the answers to the following questions:
Turn off autosuggest for EditText?
Android: Multiline & No autosuggest
In the layout XML, add the following attribute to your EditText:
android:inputType="text|textNoSuggestions"
If neither this, nor the above approaches work, then this is almost certainly a problem with the emulator and the other device, and you should contact the manufacturers directly.
See also: android:inputType (note that EditText is a subclass of TextView, which is why this attribute also works for EditTexts).
