I am planning to switch from Galaxy S4 to LG G2. I was thinking of getting the 16 GB version of the phone. But I wanted to know that is it enough? Since there is no expansion possible. When i got the S4 16 GB version, the OS and other stuff alone take up 8 GB of the space. Luckily in S4 i can go for an SD card. Just wanted to know that is the same case with G2.
