This section lists fundamental issues that must be taken into account when designing MIDP applications (MIDlets). It is important to test both the functionality and the usability of an application to ensure that the application is easy and efficient to use, and satisfies the end user.
You should also note that there might be some special issues with devices from certain series. For this reason, please read the possible Known Issues or other similar documents carefully, and test the special issues correspondingly.
