The Samsung A5 is very slim and less weight and in it there is no problem of hang and virus issue and RAM is very good its my personally experience because I have been using it for last 1 year approx and I am very satisfied with it, even I use it whole day with 4G and watch videos all the day, I have 75 apps in it. Its really very great phone and it camera clearity is very good, awesome quality and front camera also very nice.
I refer to all to use it.
