If I bought a J7 2 years ago and a J7 today in 2020 is gonna be a difference?? My J7 is telling me NOT ENOUGH Memory.. and I [ve been watching that the new phones also have 2GB of RAM and they charge you a fortune. Mine has an extension card of 16 Gb. Should I change it for a 132GB or bigger? would it stop the problem I have with " Not enough memory" ???
