Error EditText: duplicate content after clicking character with restriction

Question

I have an EditText with a restricted character. I allow numbers only as

A strange thing appears on Galaxy S4. It was not HTC Desire HD, HTC Desire X and ZTE Blade.

• I am typing dddsss
• I type in a Swedish character, for example å.
• It is not displayed because it is not a legal character, so the content remains dddsss
• I type a character, for example. u
• EditText content becomes dddsssdddsssu
• I type another character, for example. tand the content becomesdddsssdddsssudddsssut

Sometimes this happens when I also click on the backspace, so this is a button click problem.

I added android:inputType="textNoSuggestions", but that did not help.

<EditText
      android:id="@+id/comment_et"
      android:layout_width="0dp"
      android:layout_height="45dp"
      android:layout_marginRight="5dp"
      android:layout_weight="1"
      android:paddingLeft="5dp"
      android:paddingRight="5dp"
      android:background="@drawable/idea_edittext"
      android:digits="abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ,0,1,2,3,4,5,6,7,8,9,*,!,@,#,$,%,^,(,),_,+,-,[,],{,},:,;,&apos;,|,\,.,/,ß,?,~,="
      android:inputType="textCapSentences|textNoSuggestions"
      android:textSize="16dp" />

Has anyone experienced this?
