I am very pleased with the smartphone. However, this newer version of the S3 Mini missing features that had the old model (GT-I8190). Here are a few that I have found (information from the Samsung Customer): - No Smart Stay feature - Possibility of using "Samsung Hubs" to acquire music and movies over Smasung Maybe there's more "smears" but for the Stay Smart function there is an alternative app (Screebl) and the Samsung Hub I do not need. This is the way in app manager available, but can not use my knowledge.
