EditText field causing double feed characters

[zollen]

Please review the following screenshoot

1. What is the bottom word screen matching/dictionary function? It seemed to be causing double feeding in the EditText field. (multiple characters show up as a result of a single keystroke)
2. How do I prevent the double feeding issue with this word matching/dictionary function enabled?
3. Is there a way to disable this word matching/dictionary function?

Upon further investigation, the following listener code seems to be causing the double feeding issue, but I don't understand why it could causes the issue.

edittext.addTextChangedListener(new TextWatcher() {
        	public void afterTextChanged(Editable arg0) {
        	    // TODO Auto-generated method stub
        		String text = arg0.toString().toUpperCase();
        		
        		Log.d("EDIT", "Formatting text: " + text);
        		
        		edittext.removeTextChangedListener(this);
        		edittext.setText(text);
        		edittext.setSelection(text.length());
        		edittext.addTextChangedListener(this);
        		
        		Log.d("EDIT", "Formatting text completed");
        	}
        
        	public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        	    // TODO Auto-generated method stub        		       		
        		Log.d("BEFORE EDIT", "Before Text Change: " + arg0.toString());
        	}
        	
        	public void onTextChanged(CharSequence s, int start, int before, int count) {
        	    // TODO Auto-generated method stub        		
        		Log.d("EDITING", "During Text Changed: " + s.toString());
        	}
        });
