Minute 4-6

The user interacts with the home screen, opening and closing apps. RAM usage remains relatively stable, hovering between 120MB and 130MB.

Minute 6-7

The user initiates a system-wide search from the launcher. This triggers another spike in RAM usage, reaching about 150MB, as the launcher accesses and indexes system data.

Minute 7-9

The user closes the search interface and the system starts garbage collection, the RAM usage gradually decreases to around 100MB as the system releases the memory.

Minute 9-10

The user leaves the phone idle. The RAM usage slowly decreases, settling back down to approximately 60MB as the launcher minimizes background processes and caches less data.The graph illustrates how various user actions directly impact the launcher’s RAM consumption. The illustration clearly depicts how even seemingly simple operations, like opening the app drawer or adding a widget, can lead to noticeable increases in RAM usage.

This visualization helps users understand how their usage patterns affect the launcher’s overall performance. This provides an easily digestible visual representation that aids in the understanding of the launcher’s memory management behavior.

Common Problem	Potential Causes	Solutions
Launcher Crashing or Freezing	Incompatible app or widget Outdated launcher version Insufficient device resources (RAM, storage) Corrupted launcher data	Remove recently installed apps or widgets one by one to identify the culprit. Update the launcher to the latest version via your preferred method (e.g., F-Droid, GitHub). Free up storage space and close unnecessary background apps. Consider a device restart. Clear the launcher’s cache and data in Android’s settings (Settings > Apps > [Your Launcher] > Storage). Be aware this may reset your customizations.
Widgets Not Working Properly	Permissions issues App compatibility problems Launcher-specific widget limitations	Ensure the launcher has all necessary permissions (e.g., location, storage) granted in Android settings. Check for widget-specific compatibility information on the launcher’s documentation or community forums. Some widgets may not function perfectly with all launchers. Try restarting the device.
Performance Issues (Lag, Slowdowns)	Launcher not optimized for your device Too many widgets or live wallpapers Low RAM availability	Experiment with different launchers; some are more resource-intensive than others. Consider a launcher with a lighter footprint. Reduce the number of widgets and disable live wallpapers. Close unused apps to free up RAM. Check the launcher’s settings for performance optimization options (e.g., disabling animations).
