I’m with you on the memory...I’ve got an S6 Active, with no way to add memory, and would love the extra space....
...but I have no idea what ‘rooting’ a phone does. Will it still get patches and updates for the phone OS, after you root it?
The contract or user agreement in most,if not all, phones forbid rooting and even removal of pre-installed apps. You thinking it is yours just because you paid for it?
That’s why I was interested in Towelroot it is supposed to be an easy way to remove apps or move them to the SD card.
