The smartphone has become an important part of our lives and is one gadget that many of us carry most of the time. We not only use it to communicate with others, but to store personal information like email, photos, and contacts, as well. So if you plan to sell your phone or give it to someone else, make sure you erase everything that’s stored there.

Our mobile phones contain some of our most private data. There are contact details, confidential business emails, financial information, and possibly even risqué pictures that you wouldn’t want falling into the wrong hands. Factory reset is one way to get rid of everything if you’re moving on from your old phone, but there are a few other things you must do first.
