Easter eggs in mobile devices

Any Easter eggs found in mobile devices will be added to this page.

Mobile Phones
In terms of feature phones, Easter eggs rarely occurred at all. However, there have been few instances of these.

Qualcomm
Any Qualcomm-powered phone has a variable for the phone's ESN (electronic serial number). However, GSM phones don't have an ESN, but rather an IMEI. Since Qualcomm-powered GSM phones use the same set of diagnostic commands as Qualcomm CDMA phones, the ESN is read as DEADD00D (ASCII speak for "dead dude") from such GSM phones.



Samsung
In the FAT16 system images for the GT-S5611, in place of where typical "Not a bootable disk" text would be, there is ASCII art of what appears to be a crustacean of some sort:

NO BOOTCODE HERE

JASON.WU 5434 9701 723D SFS20 SPREADTRUM ________________           \/               \         0      |      /---     | \    \     /     \    \    \      \  /  \   \      \/    \   \           /\  |            /\ |             | |            /| \                \            /  ||          / / \\ ________________

In the firmware for the SPH-E2000, there is an unused graphic of a collage of (presumably) software developers who worked on the phone.



Sony Ericsson
In the Model info section of the service menu (→*←←*←*) typing in 2468 shows a message "Sony Ericsson ROCKS!"
