Well, I got a new sd for the Stylus, which has been mostly behaving. At least it charges just fine, unlike another phone I could mention (Samsung Galaxy A02s). I have been advised that before I use it I should format it 2 or 3 times. I guess as long as it's brand new that shouldn't destroy any information that is presumably not on it. Should I format it with the Stylus? After that, will it be safe to use the nonVanja to copy from another SD? If I do that, which should be in the phone itself and which in the other device? Is there a way to copy only part at a time, maybe photos or videos, for instance, and then the rest later?
