Moving to the new DuoVa
Keep everything
Installing the new DuoVa says “App not installed”? Your phone has the earlier edition. These five steps bring your questions, notes and progress across.
Step 1
Install the DuoVa Backup Helper
It installs over your current DuoVa as an update — nothing is lost. Open it when it finishes.
Step 2
Back up
Settings → Back up my data → choose Downloads → Save. Check the green line: it lists your questions, notes, reviews and images.
Step 3
Uninstall the old DuoVa
Long-press the DuoVa icon → App info → Uninstall. Your backup file in Downloads stays safe.
Step 4
Install the new DuoVa
Open it and wait about two minutes until Library shows every bank as Ready.
Step 5
Restore
Settings → Restore from a backup → pick the file from Downloads. Your questions, notes, progress and images come back. Then paste your licence key again, if you have one.
