MIUI had a lot of bugs until a few years ago. These bugs that affected daily use as well as visual bugs that had no effect to daily usage. MIUI started to get rid of the MIUI bugs completely in MIUI 13, and with MIUI 14 it became a nearly bugless operating system. However, the biggest bug that was even in MIUI 14 may be fixed in MIUI 15. This bug is the well-known bug of notifications not getting.
In fact, this bug is not the bug. In order for MIUI to power saving policy, MIUI automatically kills applications that have not been running in the background for a while. Sometimes, instead of closing it, it blocks the app from connecting to the internet to save data. Therefore, when you enter some applications, the notification that should have reached you a long time ago has just arrived.
Xiaomi may implement a new power saving policy in MIUI 15 to prevent this bug. Xiaomi may add the necessary codes to the MIUI Security app with MIUI 15 so that apps running in the background use less data and power. This way, whether you’re on the Global or Chinese ROM, you won’t risk not receiving notifications or calls.
In past MIUI versions, we could fix the problem of not receiving notifications by forcibly giving apps the permission to run in the background. Although this situation broke on its own in MIUI 12, it became smooth with MIUI 13. If you are also experiencing notification problems in MIUI 14, you can try to solve the notification problem in MIUI.
MIUI 15 will be introduced together with Xiaomi 14. Xiaomi officials have started to post messages about getting the new phone on Weibo. In this case, it could be introduced in the last days of October or in November.
