Hello, I want to buy a dual sim smartphone (HTC One or samsung Galaxy S4) but the models have 16GB internal memory - about 11 user available.
Is that enough considering the fact that I'll add an sd card.
What could take up the space of the internal memory?
I will download games on sd, all my pictures will be saved on sd.
The internal memory will be used only by the OS and pre installed apps updates?

Thank you
