Does MIUI Daemon carry spying apps?
We don’t think so. It is just a service to collect statistics. Yes, it sends information to the developer’s servers. On the other hand, it does not use private data. It appears to be that using this app Xiaomi company analyzes its user’s activity to release new firmware according to the user’s needs. Sometimes the app “eats” a lot of device recourses like batteries. This is not nice.
Is it safe to remove MIUI Daemon?
It’s possible to remove the APK, but there’s still the /system/xbin/mqsasd which cannot be removed safely (you won’t be able to boot). The mqsas service is integrated into framework.jar and boot.img as well. So it is better to force stop or revoke its authorization.
There is clearly a lot to find in this app. It’s clearly worth a deep analysis. If you have reverse skills, download the firmware, reverse this app and share with the world your results!
