Better multitasking on stock lollipop [ROOT] [build.prop] - Samsung Galaxy Alpha

Hello people, as i dig into some information about phone build prop settings and the samsung framework i found some interesting info
https://zapek.com/blog/how-to-make-your-galaxy-note-4-fast-again/
this guide is for the note 4, but works wonders on our galaxy alpha
basically it disables agressive samsung ram management, and uses the one closer do AOSP, it made my phone better, you guys can try you just need root and a build prop editor!
only works on stock samsung roms and maybe stock based roms!

---

Makes sense, I should have read the title more carefully. I'm running KK without any problems.

I don't think so, I have Lollipop and I don't have any of these lines

you shouldd only have this line: "sys.config.samp_spcm_enable=true" change it to false
=====> sys.config.samp_spcm_enable=false
you have to add these 3 manually.
sys.config.samp_enable=false
ro.config.fha_enable=true
ro.sys.fw.use_trim_settings=false

do you have the smart manager app?

---

I don't know what is it, I use "Root Browser" to browse files

you probably don't have the smart manager app, it's an stock app from samsung, the line that you don't have is to disable that app from killing any tasks.
just add the 3 other lines and you should be fine.

I rooted my Alpha today and I would like to do this tweak, but I don't know how. I see the "sys.config.samp_spcm_enable=true" line in my build.prop. My question is where do I add these lines:
sys.config.samp_enable=false
ro.config.fha_enable=true
ro.sys.fw.use_trim_settings=false
Do I put them at the very bottom of the file or in the #SAMP_SPCM section where the other line is?
My first time having a rooted android so i'm a noob

The first line you can add to #spcm as well, I think.
The second and the third lines can be added to
# ADDITIONAL_BUILD_PROPERTIES.
This is just below the #spcm section.
Note that I don't know that for sure, but I have just done it myself and it seems OK ).
Good luck mate )
