🧾 Description
This article explains the behavior and limitations of the Memory Slider on Datalogic X4 mobile scanners running Windows CE. The memory slider allows users to allocate RAM between program memory and storage memory, but due to OS constraints, changes may not appear to persist even when they do.
🛠️ Resolution Steps
Background
Windows CE is a legacy operating system with limited memory management capabilities. On devices like the X4, the memory slider is used to allocate RAM between system operations and file storage. However, due to how Microsoft implemented this control, the slider may reset visually even though the setting has been applied internally.
Key Limitations
- Maximum allocation to OS memory is capped (typically around 128MB).
- If you attempt to allocate more than the allowed limit, the slider will revert to the maximum, giving the impression that the setting was not saved.
- This behavior is by design and cannot be modified, as memory management is deeply integrated into the OS.
Best Practices
- Adjust the slider within the supported range (up to 128MB for OS memory).
- Do not rely on visual confirmation—the setting may still be applied even if the slider resets.
- Reboot the device after making changes to ensure the new memory allocation takes effect.
- Avoid frequent changes to memory allocation unless necessary, as it may impact system stability.
Important Notes
- This behavior is a known limitation of Windows CE and affects all devices using this OS.
- Datalogic cannot modify this functionality due to its dependency on Microsoft’s core OS design.
