Yesterday my s21+ told me it needed a security update. I plugged it in and left it to update.
As soon as the update was finished and the phone rebooted it started ringing an alert alarm.
Moisture was now detected in the port and disconnect the charger immediately. Also information on how to clean the port of water and debris... it was working fine before the update and I did not touch it during.
This has been caused by the update, there is no other explanation that makes sense. Even when off the phone gives the alert when plugged in... only charging very.slow via wireless. Took three hours yesterday to wireless charge from 23%
Not happy at all
