I'm project manager consulting for a charity who have a set of LG Nexus phones that are sent into schools as part of a STEM project. For safeguarding reasons when the phones are returned we need to clear off any photos, videos, audio recordings and any internet cache/history. There are a couple of apps loaded onto the phones for the students to use that need to be retained.
I'm looking for a fast solution for cleaning the phones. All the phones are connected to the same Gmail account.
I know nothing about coding for Android devices (or anything about Android devices in truth!) so please be kind with your responses.
Many thanks in advance.
Julia
