Samsung plans to launch a new Android-based tablet computer running on 4G technology later this year, reports Dow Jones Newswires. The new tablet will be an enhanced version of its Galaxy Tab models, said JK. Shin, president of Samsung’s mobile communications division, without providing further details. After launching a 7-inch device in October last year, Samsung will begin this month selling two other versions with larger screens – an 8.9-inch model and a 10.1-inch model.
