RN3Pro Snapdragon - apps to freeze & better memory management

[Tomo123]

If you are like me, and like using the official MIUI 8 firmware, you'll want to freeze the following apps ( in the attachment section ).

Also, be sure to disable "Memory optimization" and "Turn on MIUI optimization" in Developer options. After that, open up /system/build.prop and modify it by commenting out the following line:

... this:
persist.sys.mcd_config_file=/system/etc/mcd_default.conf

... becomes this:
# persist.sys.mcd_config_file=/system/etc/mcd_default.conf

Reboot the phone.

Not sure why Xiaomi decided to use their custom on the fly swap & memory optimizations - since their settings SUCK. After the tweak, you'll notice much better memory optimization, faster changing between apps, more apps kept in memory, and generally a better performing phone.

Also, remember to stop MIUI from calling back home:

Enjoy.

Does the memory optimization work and is it useful for the official Roms dev global ?

also, if you freeze the launcher, what do you use instead?

Memory oprimizations done by Xiaomy are pure crapola, prioritizing chinese bloatware instead of user apps.

I am using Nova as my preferred launcher.

The most fail tutorial on miui rom?

mcd_default.config is the setting to activate the second channel ram or Zram it's not just a swap.
It's purpose is to "add more ram" witch is good for web browsing, multitasking and for apps cache, zram config priorities system cache and kernels before caching supported apps.

Disabling it will force all the apps cache to stored on the main Ram witch can cause out of memory on some games and other apps also can cause lag.
