I have received a message that my battery is heavily damaged and given a link to repair it. The message says my phone will lock in one day. Is this message real? Do I need to click on the link?
No this is not real. I would suggest running Malwarebytes Mobile, available through the play store, as it would appear you may have malware on your device. I would strongly suggest backing up all of your personal data, as a factory rest might need to be done.
