3. Background
Issued from some operators and developers:
- “One application for all devices. Not fragmented way”
- “Implementation differences due to JSR vagueness or ambiguity”

4. LG Java Platform Overview
LG Standard for Unified Java Platform
It is for “ONE application working seamlessly on all LG mobile devices”.
It standardizes LG Java features to remove fragmentation-related issues.
It makes easy to get the information on the Java features of LG mobile devices.
It provides consistent support for Java ME requirements, JSR requirements,
and JVM behavior across all LG mobile device tiers.
