I used Challenge Touch for about a year, around 5 years ago. It has been initialized to factory settings. According to YouTube and the internet, it seems it can be converted to Android. *This type requires a developer password, so a computer or SD card might be needed? A dedicated charger is also included. The pink cover has sticker residue and stains because my daughter put stickers on it at the time. It's only included for protection during shipping, so we will not accept any complaints about the cover's dirt or scratches. The main unit was also used by a child, so it has a certain amount of wear and tear, but there are no problems with its use. Perceptions vary from person to person, so please refrain from purchasing if you are overly concerned about the condition.
