What is a common symptom of having too many applications open on a device?

Having too many applications open on a device can overwhelm its processing capabilities, leading to a range of performance issues. One common symptom is freezing or unexpected shutdowns. This occurs because the system may run out of available resources such as RAM or CPU power, which are necessary for applications to function smoothly. When the device cannot manage the load efficiently, it may freeze momentarily as it attempts to catch up or, in more severe cases, shut down entirely to prevent damage or further performance degradation.

The other scenarios are generally not associated with having too many applications open. Automatic updates typically occur based on system settings rather than the number of applications running. A device's normal speed is unlikely to be maintained when overloaded, and while an unresponsive touchscreen can happen, it is more commonly related to hardware issues or specific app malfunctions rather than simply having many applications open.
