[Q] how to get more free ram - Android Q&A, Help & Troubleshooting

how to get more free ram?? i have mmx a92. it lagging.. plz help (using Ram booster Pro)

Apps (activities) are usually cached, and "use" RAM. When RAM is needed, though, cached apps are "killed" to make space. This is all handled by the LMK (you can Google it if you want more information,) automatically. So in a certain aspect, free RAM is wasted RAM - if it is needed, it'll be made available. Struggling to get more free RAM is useless.
Take killers are also bad... Not only do they go against what I described above, but some apps use services. Those run in the background to provide various utility to the app, and can restart when killed. Task killers will kill them, but they'll only restart. So you'll only be gaining more CPU usage, more battery draining, and your task killer will actually be using RAM for itself.
In short: it'd probably be best if you got rid of your task killer, and learned to stop worrying (about the RAM) and love the bomb.

[Q] disappearing RAM

Hello!
I've had the atrix for a couple of days now, and have noticed that some ram is disappearing.
I use advanced task killer, but I don't have it set to autokill. Instead, I just press the widget as a kill button occasionally throughout the day. I haven't modded the application to kill certain things, or to not kill certain things. It is functioning just as it is downloaded.
So in the morning, after a fresh restart, i pressed the kill switch and i had 550 mb of ram (roughly). This was constant for a few hours. then around lunch time, i pressed kill switch and i had 460 something. Than now around dinner time I have only 370 something mb of ram.
Is there something that I'm missing? Like system apps opening throughout the day that are unaffected by task killer?
Anyone have any advice as to managing apps because the atrix (and motoblur) try to run a lot of them.
Also, I thought this phone has 1 GB of ram. I guess some of it is tied up in things behind the curtain
Check the ram usage on your computer, install a few programs that have services that run, then look at your ram usage.
Same thing.
regarding the ram usage. I cant figure out what the phone is doing with 500mb of ram all the time. This os is able to run on other android devices with only 512mb of ram and consistently have 200-300 free mb of ram. What is the Atrix doing with all that ram?
being prepared for docking...
Webtop/media center/ etc...

RAM not used is analogous to RAM not present in a way.
Android loads and keeps apps ready in memory for quick launch times. They are just loaded and kept, 0 CPU usage for any of them.
If u want to know more, check the thread 'android memory management' (link in my signature).

Free RAM question

Just curious why the free RAM shown in the task manager doesn't line up with the free RAM shown in Manage Applications/Running? For example right now in Manage Apps it shows I have 598MB free however task manager shows 261MB free. Obviously a huge difference between the two.
Settings -> Applications -> Manage applications -> Running shows you actual free RAM plus the amount of RAM that can be recovered from closing cached/inactive apps.
Task Manager (and third-party system info/task manager apps) will generally only show only how much actual free RAM remains.
While it's true that inactive/cached apps are pre-loaded in RAM (similar to how Windows does with Superfetch), those apps aren't actually running and can be purged at any time when the system needs RAM for running processes and services. Therefore, the amount of RAM these cached apps are consuming should be considered free, and that's why you see it under Manage Applications.
Thanks for the quick reply! Yeah, I get how Android handles the memory I just didn't couldn't figure out why it was being displayed differently in those places. I appreciate the info.

Couldn't have said it better!
Glad to help.

[Q] Why does installing apps increase the used RAM?

I've have a Nexus 7 2012 running 4.3
On a clean install, the running apps tab in the settings showed Used RAM equal to 450 MB.
After installing some apps, now the Used RAM shows to be 560 MB.
I haven't installed apps that throw push ads or run background processes. I do have some free apps that show ads though.
I tried to stop cached processes an d running processes, bur that increased the RAM use. Even app ops doesn't list all my apps.
Is there any way I can reduce this RAM usage?
ROOT your phone and install GREENIFY app ...and for your problem,it a the ever existing problem of all android phones,in actual it's not a problem at all,ignore ram usage and enjoy your device,remember using task killers will drain your battery more faster ,as killed apps will again try to run and you will be trapped in this vicious circle.

CPU usage details

Hey guys. Is there any app that can tell me about every single process running and the RAM used by it? Every single means every user and system app/service/process currently running. I generally have about 450MB free RAM when I reboot. But then slowly, RAM usage keeps on increasing, even if I have nothing running. Killing everything and hibernating all apps running in background-- that doesnt help much. Android hardly shows any details..it just shows the currently running user processes and services. That "system" usage of the RAM keeps on increasing and doesn't decrease unless I reboot.
Any way to view what eats the RAM up? And kills those stupid useless bastards?
try MyAndroidTools and look into process

Nice app man, thanks

Low Memory Killer, Zram settings for 2GB Ram

For reference, phone is on lineageos android 8.1, has 2gb of ram (1807mb to be exact). I currently have set zram at 256mb.
From monitoring personal usage, android straight up uses 1gb of ram (it goes as low as 900mb after internal app force kills, and as has a 1.2gb after opening some light apps but no internal app force kills).
For example, I know that if I play pokemon go, it will sometimes kill running background apps (like afwall and betterbatterystats), despite having 'enough ram'.
What I mean by this is, before launching pgo, the os with everything running normally (example- tasker, afwall, betterbatterystats) ram usage will be at 1gb.
After pgo launches, the game will use ~600mb of ram. This should leave a safe 200mb of free ram. However, any time I switch out of the game, android will kill the app despite ~200mb ram is free.
Playing pgo will also sometimes background apps as I mentioned, but it feels completely random. I could be doing the same stuff for 10 mins and it will kill the apps, but sometimes, I could be playing for 20-30mins and no background apps are killed.
I've played around with the LMK settings a bit, and I admit I don't understand the settings despite reading on the little, outdated documentation on it.
I don't know if the 256mb zram counts as reserved/invisible ram, but I did set it at 0 and didn't feel a difference.
I also tried the 'ram management fix' magisk module and again, didn't feel a difference.
tldr - How do you properly set LMK and zram settings. From personal usage, android seems to never use the last 200mb of ram for me and starts killing apps despite having ~200mb of free ram.
My answer may no longer serve you, but I hope to help other people.
As you already mentioned, the lmk cleans several applications before reaching that limit (minfree 200mb) the higher the number ... the more applications it removes, although drastically reducing the values would cause a ram saturation and give performance problems. I recommend that you put these values 9806,14136,17848,21560,24448,28278 and 1gb of Swap by default for 2gb of ram
