I cant find the lesson that i get with lingots, and I cant use the Umlauts for German.
Hi natiz, If you hold down for a second or two the letter to which you want to apply an umlaut (e.g., u), several more options will pop up, including accents and umlauts. If you hold down the "s," you'll also get the option to use the β. This works on Galaxy's as well as the Kindle.
PROTIP: If you hold down the space bar on the Kindle, you can switch the input language, which will help with the special characters and spell-check.
