首先最简单的就是我们要检查的就是微信设置里的新消息提醒，点击设置后，进入新消息提醒界面。
在新消息界面中，查看是否接受新消息通知这个选项是否有关闭。
但往往问题不会这么简单，还有个原因一般来说就是微信进程在后台被杀掉了，笔者使用的是红米，经常会清理后台应用程序。长按home键，可以调出后台程序清理的界面，按住刷漆板，即可把所有后台的应用程序给杀掉。
这样做的方法是可以释放运存，但无意间也把微信在后台杀掉了，自然也无法弹出消息提醒，红米手机的简便解决方法就是在长按home键后出现的界面中，把微信图标往下拉，你会看到图标上会加把锁，这样在你清理后台程序的时候，不会清理掉微信进程。
顺便说下应用程序的查看，可以在设置-应用菜单中的正在运行中查看到，微信进程是否有在正常工作。
