My basic smartphone has a tiny internal memory capacity of 200 MB. I inserted a 2 GB microSD card.
With the Link2SD app, you can move apps to the SD card. With the paid version Link2SD Plus, you can move even the data files, which could be quite large for some apps.
Is there a free alternative to Link2SD Plus? Is there a free app that will let us install other apps on our external SD card?
