What Happens When You Delete Data From Your Phone?
When you delete images, messages, or apps from your phone, they don’t necessarily disappear immediately. The phone only indicates that the space is now available for new data. But until then, the deleted data might still be running in the background, so deleting files isn’t always sufficient.
A factory reset can delete data by removing access and settings, but it’s not foolproof. If the reset is done too quickly or if your Google or Apple account is still linked, tiny pieces of data can remain. This is why protecting your data before selling becomes very important.
