ERSP: Steps to close unwanted applications/running services on Android OS
Because the Android OS can run many applications simultaneously, these applications can build up and over time, may accumulate to a point that could affect how DejaOffice runs on your device.
You can manually shut down unnecessary applications on your device. Here's how:
Open Menu > Settings > Applications > Running services. For each service that you tap to stop and close, you free up resources on your device.
This should improve the performance of DejaOffice, overall. Pay special attention to two numbers at the bottom of the screen - this indicates the available memory. The higher these numbers, the more available memory your device has to run applications like DejaOffice.
If DejaOffice continues to run slowly on your device, please let us know.
