手机烧录完成后，开机向导发生了ANR的问题
然后发现，问题发生的时候存储颗粒性能急剧下降，IO降速严重
请问发生ANR的原因是什么？为何会导致存储颗粒性能急剧下降？

引用chatGPT作答，这个问题的原因可能是ANR（应用程序未响应），这意味着应用程序在执行某个操作时无法响应用户输入，超过了一定时间阈值。在这种情况下，Android系统会强制关闭应用程序。
ANR可以由许多原因引起，例如主线程被阻塞或死锁、CPU或内存使用过高等。在这种情况下，看起来ANR可能是由于开机向导执行某个操作时被阻塞而导致的。
存储颗粒性能急剧下降和IO降速严重的问题可能是由于ANR发生时存储系统无法正常工作，导致性能下降。这可能是由于ANR导致了一些IO操作未完成，导致存储系统无法正常读取或写入数据。如果ANR发生在开机向导等系统级别应用程序中，那么存储系统的问题可能会影响整个系统的性能。
