Sagem phones uses different keycodes for numeric button. For example pressing button 1 returns keycode 48 (other phones returns keycode 1). This is correctly handled by examples. Just be informed.
Seems this model have font of only one size. As a result commands Set(font,...) and Set(list,font,...) will not works.
Instead of other phones (not sure about other Nokia phones) it needs to use Green button instead of Push Joystick in main screen of java client.
This phone contains the worst Java realization i've ever seen. Autoscrolling of long lines in list screen and file manager screen will not work. Control (main) screen will not support autoscrolling of title field. If You plans upload icons to the phone it needs to convert them previously by Pngout utility. Siemens-S65 could not handle icons created withother tools (for example Gimp) correctly. Run Pngout utility with "-c6" option.
If You use other Siemens/BenqSiemens phone in Server mode try to set "fix_siemens" parameter to "on" if something goes wrong with java client.
