Notch Notifications for MIUI unhides notification icons on the Xiaomi Mi 9, POCO F1, and other notched Xiaomi phones
Newer Xiaomi devices, especially those with a waterdrop notch display like the Redmi Note 7 Pro and the Xiaomi Mi 9, handle notifications in a rather strange manner. Notification icons appear on the top left corner of the device when the notification arrives. But after a couple of seconds, the notification icon disappears, even though the notification is not dismissed and continues existing in the notification panel. Notch Notifications for MIUI by XDA Senior Member SirTAVARES tackles this problem by adding an overlay with the notification icons.
Notch Notifications for MIUI provides a temporary solution to the disappearing notification icon issue until Xiaomi rolls out a permanent fix for Global Stable ROMs (the issue is claimed to be fixed in newer Global Beta ROMs). You need to install the app, provide the permissions it needs and then set X and Y axis padding according to your phone’s DPI and set the icon size. The end result will be that icons for notifications will stick around till the notification is cleared. Do note that the app will not be able to display notification icons on the lockscreen because of system limitations. You are also advised to lock the device in memory to avoid clearing it while clearing apps.
