My apology if my question has been addressed in another thread(s) I did not find. How do you wipe a phone completely clean? My husband has a new job w/ phone, so we want to get rid of his Charge. I have a DInc that I plan on shedding before year's end, and I too want to make sure all personal info, pics etc. are off. Do I just learn how to restore to factory setting & remove the sd card? Obviously I'm not tech savy, so please explain for the smartphone dummy. Thank you very much!
