Hi guys,
I have some problem with an app for bank access.
I have changed my bank account and I think that app call bank server and crash because my account was changed.
Bank have cancelled my old account but is possible that something is saved into my Note 4X ?
Can I delete all files stored by this app?
Many thanks for help.
