I wiped the phone today – a full factory reset.
Logged into the Google Play Store using a test account , installed MalwareBytes Anti-Malware , updated the database and performed a scan.
Android/PUP.Riskpay.Excel.lib.kxqp malware was found immediately in the pre-installed 2Accounts app.
I have attempted to contact Haier via Twitter and Facebook but have been ignored so far.
Wonderful customer service!
