Hey guys,
I have a rooted J320F and to get more RAM, i used the ROEHSOFT RAM EXPANDER and it worked a day.
After restarting my phone, the app says: device or sd busy .
This error pops up not all the time. For example: Now i can start the app and activate the Swap but the system dont use VRAM. I have 1,5Gb free from 1,5gb.
i found only this post

The RAM Expander uses a swap file to be used as a ram, it is a virtual memory.
Virtual memories are slower than physical ones.
Your phone will become slower than ever before.
The app is for those phones that have very low ram, near to 512 MB
I am saying this from my own experience.

Hello anybody who can help me and other people understanding what we see in applications which show memory info.
I want to understand why "meminfo" shows total RAM 335Mb and Internal phone storage: 420Mb (it is on my phone).
Official info from http://developer.sonyericsson.com/wportal/devworld/phones/phone-overview/xperia-mini-pro?cc=gb&lc=en says it should be the next:
- Internal phone storage: up to 320 MB
- RAM: 512MB !!!
One of my thoughts is that the part of memory is used by video-card
Please explain me why it happens
Some is dedicated to the graphic and some more is reserved from the system. The total is 512, don't worry.

Think of the Android Operating System as a Virtual Machine on your phone. It needs some RAM in order to work.

Can you modify the values besides a VM usage ram ?
No. What you need in order to have more "system memory" which actually is part of the RAM itself is swap. Swap creates a partition on your sd card which then is used by the system to store temporary data. The thing is that its a double edged knife. NAND is 100 times faster than your typical SD card, so loading apps and/or part of the system on your swap partition might end up in a slower overall phone. But we wont have such a problem with our devices, because the system itself doesnt take all that much storage itself.
The only device so far that i know, which had a problem with storage was the Desire Z i own, when you wanted to flash a custom sense 3.0 rom. Then it needed different partitioning in order for the Sense 3.0 to fit into the device.(the device isnt a sense 3.0 device by default).
If you have many apps that you cant seem to fit in the 320mb of free memory, i recommend you install an app2sd application.
I tried so many time,
but can not use.
->Creating swap file OK
->Changing permissions OK

swapon: /sdcard/swapfile.swap: Function not implemented
Plz how to solve this problem. swapper2 said (If On not working on your phone, try to download busybox)
The kernel doesn't support swap by default.
I would like to ask u,my bro K900
I don't understand Swapper2, I look tutorial for swapper2.
But they said
" Swapper preferences: (for kernels that doesn't have swap partition support)
Run swapper at startup (put a check)
Swap place: /sd card/swapfile.swp (you can place it in a folder if you don't like a messy sd card structure )
Swap size: MIN: 10 MB MAX: 256MB RECOMMENDED: 32MB (choose any)
Swapiness: RECOMMENDED: 10MB SYSTEM DEFAULT: 60MB MAX: 100MB (choose any)
Safe unmount (put a check)
Safe remount (put a check)
Advanced preferences: (for Kernels that supports swap partition only)
Use swap partition (put a check)
Swap partition: /dev/block/mmcblk1p2 "
Plz, i don't know about this. sorry for my english bad.
Why do you need it? Besides i've never heard creating a swap partition on the internal storage given that the U has no SD card slot.

But It can create swapfile.swap on internel storage. I would like to ask more memory on my XP U ( I also used RAM Manager & Super Manager ).
My memory always 80 MB to 100 MB. How to do ? Plz. my bros. Other App?
80-100 is fair enough. Remove the bloatware and it should be~150mb free at all times. Anyways free Ram is wasted Ram. I still don't think you need swap
Sent from my ST25i using Tapatalk 2
I have usually 170mb ram free.
have you ever heard of v6 supercharger?
anyway I don't think creating a swap is necessary since 512mb are enough for the heavier task this phone could do, I usually have around 150mb free ram, and that's enough to keep browser, music player, and another whatsoever-might-be-needed application

150MB? Wow? How do you do that? I don't have 150MB after boot neither.

Close the running services. If you're rooted block apps from re spawning on their own using rom toolbox. This keeps the RAM free

I think it isn't a good idea. The swap can kill the sd cards easy, but U have internal storage, so you can't replace it. So it could be an expensive fun.
Services are restarting itself again if I stopping them. And I don't have root.

swapping? i dont think we need it even i have 80mb of free ram even after reboot and less than 40mb without clear memmory, i use my phone heavily playing game HD browsing music watch movie etc etc etc and i have not reboot my phone for a week, 122hours exactly there is no problem i found
yep this is smart phone and it should be know how to manage it's own ram
Is it possible to extend RAM in my Archos 80 G9? I'd prefer 1GB instead of 512 MB, I run out so often from available memory and the whole system stucks for long seconds because of this.
Thanks.
Unfortunately not. Tablets are not like desktops or laptops where you can simply add another stick of ram. They run off SOC's (System on a Chip) where everything is integrated onto 1 chip for convenience. There is no way to upgrade the ram chip on these.
You can add swap, but the performance isnt gonna be as good as 1 GB ram.

And how to do that?

Yes you can...
But don't swap if you don't have HDD model... (Or swap on network or USB hard drive...)
Write cycles are too limited with flash, internal or not, memory and your tablet (or SD card if you swap on SD card) will wear out quickly!
I have a HDD model, but I don't know how to add swap...
Can anyone explain it?

First : You have to be root
You can do that with a few commands (in a shell script)
You can find scripts that can do that searching on this forum...
You can also download a Swapper on playstore (Swapper, swapper2 etc...).
Thanks everyone.
Great! I hope will work on my 101g9 250gb.
Hi ,
I've been searching all over xda for an app or a script that could give more control over a swap file present in the SD card .By more control ....I mean ...is it possible to select which apps ram usage can be swapped to the file and is it possible to prevent ram usage of some apps from being swapped ? The reason is that after 1 or two days the device becomes extremely laggy and have to restart and apps start freezing just with a swap file of size 50 mb.
I use an LG L3 running on large rev 2 with SD merge .
For the swap file I use Ram expander .
Thanks in advance
Guys, I have faced a problem. Hope, someone can help me.
My android device has 8GB internal storage and almost half is available. But in settings it shows only 1GB of apps can be installed. Though I have manage all of my internal storage space free, it always shows I can install only 1GB apps. That's why I can't install apps(apk) which is bigger than 1GB such as NBA2k15 and insufficient storage problem in play store after installation of small amount of apps.
Please help me.
