When you run top, look for the following columns to diagnose issues with an OS update:

The update introduced higher CPU load on kswq_hal, likely due to:

In the world of Android firmware development, userdebug builds occupy a critical middle ground between production user builds and engineering eng builds. They provide root access, extra debugging tools, and relaxed security constraints—ideal for testing—but they also introduce unique instability risks during system updates. The case of kswquserdebug and the observed abnormal behavior of the top command during an OS update illustrates a recurring challenge in embedded system maintenance: balancing diagnostic visibility with update reliability. kswquserdebug os update top
