When you click on backup. What's the output? Is it ask you to safe a file? Provides you with seed? Or anythig else?
Under Safety is Backup Wallet. It says your backup will be encrypted with the chosen password and written to external storage. then when you
back it up it says it's been baked up to your device but that you should archive it somewhere externally basically (in so many words). Or if it's a removable SD card then the backup would be stored on that card.
Hmm, to me it seems it is not the HD type (but I could be wrong). I highly advise you to use some HD one ( for reasons stated above ).
