Tablet has 1GB ram Samsung Galaxy Tab 4 T231 good but Samsung Galaxy Tab 4 T231 does not faster performance. Samsung Galaxy Tab 4 T231 is hanging after we play big size games on it. Storage of tablet is 8GB but it not 8Gb. I expandable its storage to 32GB sdcard then tablet heating too much and it Samsung Galaxy Tab 4 T231 is hang more than before. So I am not compatible 32GB sdcard. Tablet display is very large 7inches but not big things important the quality of that is very important and New Tab does not. Camera of tablet gives very bad quality of picture. The micromax canvas tab p480 is kids tablet.
