thank you so much, was looking for this.

Thanks, it was very useful

Thanks a lot. Just curious: why do you guys need to detect if the device is running MIUI or HyperOS?
In my case, it was because the player notification of my app (PlayerNotificationManager with MediaSession) makes the phone extremely slow and unusable, the users needed to reboot the phone...

It's because there are some Android APIs that are broken on MIUI but somehow got fixed on HyperOS. For example, the per-app locale settings APIs introduced with Android 13 are broken on MIUI running on Android 13 as well as 14, but they seem to work perfectly fine on HyperOS based on Android 14. So, we need to differentiate to avoid blocking certain features for users whose devices/OS are capable of supporting them, based on the assumption that they're all running MIUI and that it doesn't work on MIUI. Also, note that MIUI is now an EOL skin, as Xiaomi replaced it with HyperOS. MIUI no longer gets new updates and is being replaced by HyperOS on existing devices via OTA updates.

In my case because HyperOS doesn't grant BLUETOOTH_SCAN, ADVERTISE and CONNECT, when permission NEARBY_DEVICES is granted through their dialog. But when granted through App Permission Settings (The ones made by Google), they are granted as well. Frustrating, took me some time to find out. Also for other permissions "Open new windows while running in background" which is granted differently in stock Android.
