We have a Samsung Galaxy Star advance with 1 GB memory. It is very slow to respond and playing games is a very tough task with this phone. Battery is okay and comes for a long time if we do not play any games on it.
Watching you tube videos and checking mail are possible and easy. Sometimes the phone hangs and even a restart does not work. You have to manually remove the battery and put it back to get it working. Overall its an average phone
