I have an application that sends an EMS to differentiate between Nokia Picture message support and EMS support. If I send a 7 bit message with UDH then EMS phones can see the predefined animation plus text whereas Nokia phones only see the text.
This works fine on all the phones I have tested except the 3510 which it locks up and on taking it to a dealer apparently requires the firmware reflashing. UDH I sent is 040D0200040D0A.
Any ideas anyone?
