SSM 32273 - MyTouch Blank/Black Screen, Application Desktop.exe Error Message, Or System Reboot With Display Message Performing System Maintenance Some MyTouch equipped vehicles may exhibit a blank/black screen, Application Desktop.exe error message, or a system reboot with a screen display of Performing System Maintenance that occurs frequently. Unique characters stored in phonebook entries, or the phone's name, may be creating these condition. To restore system function, the customer’s phone must have all special characters/smiley face emoticons removed. Once all special characters/smiley face emoticons are removed from the phonebook and/or phone name, perform a Master Reset on the Accessory Protocol Interface Module (APIM), then repair the phone to the system. Engineering is currently investigating this condition. Monitor OASIS for updates.
