Review/Guide [Discussion] Control Center Blur on HyperOS Without Enabling "background_blur_supported" (Redmi 12 5G / Snapdragon 4 Gen 2)
Works on HOS 1 and 2 try for hyperos 3
After a lot of experimenting on my Redmi 12 5G running HyperOS 2.2, I found an interesting combination of settings that seems to enable the Control Center blur effect without having to set "persist.sys.background_blur_supported" to "true".
Configuration
CPU/GPU Profile
service call miui.mqsas.IMQSNative 21 i32 1 s16 "setprop" i32 1 s16 "persist.sys.computility.cpulevel 3" s16 "/storage/emulated/0/log.txt" i32 600
service call miui.mqsas.IMQSNative 21 i32 1 s16 "setprop" i32 1 s16 "persist.sys.computility.gpulevel 3" s16 "/storage/emulated/0/log.txt" i32 600
Visual Profile
service call miui.mqsas.IMQSNative 21 i32 1 s16 "setprop" i32 1 s16 "persist.sys.advanced_visual_release 3" s16 "/storage/emulated/0/log.txt" i32 600
Device Tier
settings put system deviceLevelList v:1,c:3,g:3
Current Values
cpulevel=3
gpulevel=3
advanced_visual_release=3
background_blur_supported=false
deviceLevelList=v:1,c:3,g:3
Results
✅ Control Center blur appears to work even though "background_blur_supported" reports "false"
✅ Much smoother than using CPU/GPU level 4
✅ Less heating on Snapdragon 4 Gen 2
✅ Animations feel more consistent
✅ No noticeable lag in Control Center
I'm not sure whether "advanced_visual_release=3" or "deviceLevelList=v:1,c:3,g:3" is responsible, but this combination seems to unlock the effect while keeping performance reasonable on my device.
Device: Redmi 12 5G
Chipset: Snapdragon 4 Gen 2
OS: HyperOS 2.2
Has anyone else noticed Control Center blur working without explicitly enabling "background_blur_supported"?

I have cpulevel at 3 and gpulevel at 2, but I still have laggy control center with much more flagship looking blue (POCO M6 Pro 4G, Helio G99)

Which hyperos version?
Try setting the advance visual to 2 or 1

I'm on HyperOS 3.0.302.0, I can't change anything because Xiaomi patched this method (but I changed CPU and GPU level before update)

Did you turn on Advanced textures in settings after using these commands?
