Background:
Unfortunately due to a calibration error a batch of R306 units will show a warning message "Serious error. Stop charging. Stop using your phone. Contact a Sony Ericsson Call Centre" when fully charged.
The cause is only a measuring problem, so there is no risk to the customer.
Solution:
The unit should be swapped since there is no way to fix the message with repair equipment.
Please send these units to SBE or according instruction from your local Sony Ericsson company.
Please see below document for the affected IMEI / Market. |
