How to add more ram to our tiny devices(Through SD card;) )

http://forum.xda-developers.com/showthread.php?t=683123
How to use Swap space on SD to increase ram on our devices so we can run more demanding apps.

swap is possible only with custom kernel, so it will not work for us

I believe that doixanh proved more than enough that custom kernel is not needed for any kernel modifications Still, we would need a module.

but i don't think that he should make swap module it will be better if he will finish this

Well, it's up to him what he wishes to develop

IMO swap is useless for Android. It has its own memory management already.

And it would certainly take a high class sd card, AND it would be harmful for it So next time we should just buy a phone with bigger RAM memory

So, how can we increase the memory through SD, my finding isn't good ? If not, how to do it the right way?XD

I don't really care about my SD card's health XD i just want more ram XD

But what do you need slow RAM for? RAM is very dynamic and since we already use app2sd it could even slow your device down instead of enhancing performance...
EDIT: Well, maybe it would be faster if you have a class 10 card...

Yeah SD is slow and putting swap there will be incredibly slow.

Yes, but i want this because you know that there are some applications that won't run on X8 because of it's low ram...so, i dont care about about speed, also, i don't use app2sd, so no slowdown, I am using Class 4 card

Yeah I know. Just my opinion

So, is there a way of using ram just for the ram consuming apps, to make X8 able to at least run them? (You already released an SD card speed fix, so it should go a bit faster...Can you help me, cuz i really like running RAM hungry apps and i don't have enough ram :|

No I don't know about that. Haven't tried swap thingies yet

for example, there are games, like dungeon defenders that requires 256 MB of RAM at the runtime (it's the requirement of unreal enginge 3 i belive). some guys have managed to run the game on LG swift, which is pretty much the same device as x8 when it comes to hardware. maybe it's not running too fast (although i saw some video where it was even faster than on some more powerful devices), and it's not quite playable, but some people might still enjoy it. and without SWAP, it's impossible; and it's just a one example.

Thanks for supporting my ideea XD We really need Swap for Ram Hungry apps

Yes. great. ideA. but... is posible?

The app that does this on market requires custom kernel so might not be possible atm

Android 4.1.1 Taking so much ram?

Hi,
I was wondering how can Android 4.1.1 use around 580MB-600MB of Ram with everything closed ? I even tried to wipe all my data/apps.. Still always at 580MB (around). My iPad 2 has 512 MB Of ram and always have 256MB available. (Means the system use around 256MB too). Is it normal that Android use twice the ram iOS would?
If not can it be fixed? If yes can it be improved?
Thanks

Free ram is wasted ram. Your device is supposed to use all the ram it can.

Your Nexus 7 has double the amount of RAM than your iPad 2. It may as well be used!

Don't worry about free ram space. The android system manages ram really well.
Clears processes if your using ar am intensive app.
Since the memory is not being used it may as well make your nexus7 smoother.

Alright thanks you ! I will stick on these answer

Yeah but I thought the point of having more ram was to have more available for bigger apps

Is it good to Use Swap?

How good or bad is it to Use a swap partition, pros & con's ?

I guess its okay to use swap. Swap increases your ram and so you can preform better multitasks.
I think the con is that the phone gets slow if your SD card is not good. But i am really not sure on this one

SWAP expands your RAM, so when you have it, you can open more apps than than you could without it.
If You're not trying to run many RAM-eating apps at the same time, you're only wasting your SD space.
I close every app i don't need, so SWAP i useless for me. Also i'm using Dorimanx ROM, which when SWAP is enabled has no built in task manager. If it wasnt like that, i would probably have it, just in case.
About slowing phone down: SWAP will never work as fast as RAM, since it has slower access time than native RAM. It's just to keep everything going even if you ran out of RAM, maybe a little slower, but still.

Swap memory

I am considering using swap for my galaxy y. I just want to be able to use 3-4 web poages on dolphin or use facebook messenger without my phone slowing down so that my contacts and phone app takes forever to load unless i reboot.
Is 32 mb enough? or should i go for more? what are the disadvatnages of using too much swap?

Dude !! I m using ram mannager pro with 256 mb swap file which gives a realy hard multi tasking & smooth experience !! I m also using pure performance for better result !! See pure performance in development thread of galaxy y!!

If I was you I would reinstall your rom or use a different one - I use dolphin and have 5 pages open without any problems and I dont use swap which could shorten the life of your sd card

I just wanna know if using too much swap can make your phone slower. Like 32 mb vs 256 mb. any disadvantages in choosing 256 mb other than sd card life?

Why does nexus 4 use more ram then s3 mini

Guys my previous phone was s3 mini which had cm 11 installed. It used 400mb of ram and nexus 4 with same ROM 900. Can you explain that :0

If the system has more RAM will use more of it because it will make things faster.

N4 uses on avg about 400mb
You have a lot of cached apps? Facebook alone can eat up to 100mb
And why do you even worry? N4 has 2gigs of RAM....

When you start out with around 1.8gb of RAM.
Have to deal with the fact that once you get below 500mb of free ram the device turns into a lag fest. Add in the 400mb or so that just running the system uses.
What's funny is the pr crap from Google. Oh we made kitkat to run on lower end devices. We used a crippled nexus 4 with 512 mb or ram. Well they failed. The OS still runs like a three legged dog when it's "low" on ram.

Interesting..
Any way to fix this?
I used greenify on s3 mini.
But I guess I won't be needing that since 2gb of RAM plus snapdragon s4 pro is just too high for phone to lag.
Nexus 4 is still high end phone, right?

Oh come on guys....it is 2GB of RAM and it is STOCK ANDROID! This is not Touchwiz for you to be scared of running out of memory.
I'm a power user and i have never had more than 1GB of RAM used..... just install greenify and enjoy life
Also, what lag? Only lag you will see is if you feck up your kernel settings, if you turn of 3 cores completely or underclock to 700mhz lol

I'm using CyanogenMod not stock and I don't mind about RAM but it's simply plain weird that s3 mini uses less RAM on same ROM and android version.

What would you do with free RAM instead of using it to cache and run services and system processes? Free RAM is wasted RAM

Not really. Compared to this year's flagship devices, our nexus 4 cannot be considered as a high end device. Having said that, it still performs really well because of the stock android. Only drawbacks are its camera and battery though.

5 hours of SOT is good for a 2100mah battery....and regarding the phone status, it's still a High end device.
Just because it doesn't work at 2300mhz or that it doesn't have a 1080p display it doesn't mean it's not a high end device.
It performs as a high end device, which is what is important. What is the point of 2.3 Ghz when my N4 can run lag free underclocked at 1.1 Ghz?
It's all marketing

You won't run out of RAM because android went let it happen.
The system / apps uses more than 1gb all the time. There should not be a need for root and greenify etc
You can see lag everywhere. It's there no matter what the die hard android fans say. The launcher lags in the widget selection part. Google plus lags and so on
Its funny how people see what the want to see. Most of the same people are also the ones that move on to the nexus 5 and say wow this is fast, I though the 4 was fast etc. They then immediately see the difference. Something you never hear from anybody going from a iPhone 5 to 5s.
To other posters yes in theory free ram is wasted ram. But it's not wasted ram when you need to keep around 500mb free to keep your system running as it should.
Again. On ios you can run right to you run out of RAM and make the app crash. You won't notice it until happens. On Android... Oh crap. There goes the lag fast. Clear all greenify and so on. All while having more than 400mb of free available ram. Which is more than you would have on a system with only 512 mb.

Lol what are you talking about
I have no lag....not in G+, nor in Widget drawer.
iOS and Bada OS are similar. Bada 2.0 on my old Wave 3 was iPhone fast, and it only had 512 megs of RAM.
iOSBada & Android work differently.... what i've noticed that these closed source sh1ts have runtime similar to ART, hence they open up apps fast (even the Wave with 1.4 ghz single core & 512mb ram)

Whether it's better or not, I don't know because I don't use CM. Either way, it is good imo. You can try but not all phones are made the same. So, if it is good on mine doesn't mean it's good on yours too. You just need to try it yourself.
Note: If you are using CM, use the CM version.

That is why my friend, read what I said carefully. I did say it performs really well despite not having all those specs you said. 5 hours? Yeah, on wifi I can get up to 7 hours but on 3g connection, not even close to that. Best I can get so far with 3g all the time is 3 hours. That's my opinion anyway, why should we settle on good when it can be great. I hope the next nexus (if google still make it) would have a bigger battery. That's all.
