Research direction
Start with the Android traceback in gui/kivy/uix/dialogs/password_dialog.py and follow the password-update path through wallet.py, keystore.py, and crypto.py, especially pw_decode and check_password. Reproduce the standard-wallet password update on Android and determine which stored value reaches base64.b64decode; done means the reported flow no longer raises Incorrect padding and has coverage for the failing case.
