After googling and searching alot, i didnt find my answer
so hope someone can help me here, and this will help others too.
so install apps on SD Card or Internal memory ?
The internal phone memory is generally of a lesser amount than the amount of the memory you'd have on a SD card. You cannot really change the amount of internal memory you have on your phone but you can always get a new SD card with a larger storage capacity.
So when you have apps that need a lot of space it is better to have them installed on the SD card.
will installing more apps on internal memory make the phone run slower ???
I don't think it will make the phone run slower, but you'll have lesser storage space for your other data which is stored in the internal storage like your contacts etc.
i have an HTC Sensation XE running on Darkforest ROM, this is my RAM (pic) how can i increase the free memory, thats the max i get around 180MB free
View attachment 1034360
Can I know why you wish to free up the RAM? In most cases you really don't need to because the OS manages that quite efficiently. It will free up the RAM and make room for the running applications whenever it needs to.
cuz in some apps after opening them for a while and try to close this app the phone restarts, so i read that its cuz of low RAM
please correct me if am mistaken
180 mb is a lot of RAM for a single application to use. And as I said, the OS, is pretty good at managing it. Although I cannot exactly tell you why your phone might be restarting when you close some apps, I don't really think it would be cause of the low RAM.
I checked my phone and it had about the same amount of RAM occupied as yours(i.e. 2 thirds of the total capacity). Then i started a game called Fruit Ninja which uses 3d graphics, which should need a lot of RAM. Then i pressed home and checked the RAM usage again. Even then the RAM usage did not go up by much.
You should try to verify this on your phone too. Check the amount of RAM thats being used. Then start the application thats causing the problem. Press the home button and check the RAM usage again.
An app will probably run quicker from internal mem because flash storage is much slower, but youre'e limited by space constraints.

Well it might load into the RAM quicker. But I don't really think there is much of a difference in speed while its running. Unless there are a lot of loading and writing operations.
Pay attention to one thing: internal storage and ram are not the same thing.
Ram is commonly allocated on a high speed journaled partition and it is 1000 times or more faster than both the internal emmc or the external SD (that'd why a swap partition is not as fast as real ram).
Just for the I/O parallelism, an app installed on the external sd could very likely run faster than one that resides in the internal emmc. Anyway, it also depends on the class of the external sd, though the class counts only when writing sequential data, while reading could even be faster when using a lower class SD.

Doesn't an application get loaded into the RAM first when its started? So would its execution speed still depend on the sd/internal memory?
I thought that would come into the picture only when theres some kind of read/write thats happening to the sd/internal memory...
Well, if it is true that any app run inside the dalvik vm and such vm is able to run simultaneously multiple apps in its sandbox, I suppose that any app could need to access its installation files and its stored data while running.... I am not sure, anyway, it is just what I believe it could be.
To be true, my supposition mostly derives from what I've experienced with chrooted linux, which run faster when the .img file is stored on the external sd.
Anyway, if it should be as you say, the app's speed would be totally independent from the support where it was installed.

That is what I exactly meant. Although it differs from case to case, an application typically loads all the stored data it needs at the start. And then throughout the execution of this application, loading/saving of data is generally rare.
Of course this is a very generalized statement and such things are handled differently by different applications depending on how they were implemented and what they are intended to do.
Consider for example a game. The game would load all the textures, images, music it would need for a particular level. Then throughout the entire period of the level the game wouldn't need to load any data. It is only when some different support data would be needed by the game, or if the player's state is to be saved there would be a read/write operation. At such a time only would there be a need to access the sd/internal memory. So it really doesn't make the difference of where the game is installed very noticable.
Now on the other hand if you have an application say an Image viewer application which loads an image from the the sd/internal memory every time the "next" button is pressed. Then, maybe you'd have a noticable difference based on where the image is being loaded from. But even typical image viewers implement some sort of image caching to reduce such excessive loading.
Widgets
I had a problem where apps that used a widget option did, not give that feature anymore when the app is moved to the SD card...

So what is your advice. When I'm installing programs, are all programs able to work off of the micro sd card? I want to save memory but should some programs be installed on the internal memory? What is the thought behind it?
some should. look at it like this:
memory: anything that you want to always have on (at least most of the time) and will stay running when your phone goes into hibernation.
Ex. BeeJiveIM, gyrator, callerutility, etc
storage card: anything that you don't use that often and want to start up manually.
Ex. Skyfire, Google Maps, Music ID
---anything that you want on a storage card i would recommend you putting on there BUT sometimes things you want to load onto your storage card only will download to your memory.
Thanks I'll take your advice.
So I guess my real question is, will I see a big speed difference if I"m running a program off of the card? Will programs run faster/better if they are installed on the internal memory? Or does the class or speed of the memory card come into play when you're tranfering files?
in performance no, not at all. only thing is different is that when the phones suspends itself after so many seconds the internal card also suspends itself after so many seconds after the phone is in hibernation, so therefore i would use it for things that you need right now and not over a long period of time.
Is there a way too increase the internal memory? I use Android booster to close all running apps before I run Zinio. After awhile I would get a warning that I'm running low on memory. I have the 250GB model. Is it possible to use some of the hard drive for additional memory when the internal memory runs low?

Apps that are able to be moved to the SD card are dependent on whether the developer has enabled that option. To do so, go into settings > applications > manage apps and individually go through them. There should be a button that says either move to phone or move to SD, if it is possible to do so.
To see what is really taking up space, run DiskUsage - Android app on AppBrain or a similar app and it hopefully will tell you what is the largest items.
Also, sometimes just clearing caches out will help as well.
don't forget to hit thanks please ....
I believe he is talking about memory, not storage. currently no one has posted any success in soldering in new RAM. The Swap option gives you some limited ability to use storage as memory, but it can only do so much.
Moved to proper forum.
You have 2 options:
Compcache
Swap
For both you need UD
And:
You shouldnt use a Memory Optimizer or so These apps ruin your Ram usage
Hi,
I actually picked the S2 over the Sensation because of the slightly higher specs and the fact that phone has 16gb internal memory. Being new to android (switch from iPhone) I really don't get what device memory is and why it's filling up so fast. I have barely installed 5 tiny apps and already 140Mb out of the 1.97Gb has already been used. I installed loads of apps on my iPhone and I intend to do that same on my new one so could someone please explain this concept of device memory and what exactly is stored in there. Also, if I run out of device memory, how do I free it up or increase the 1.97Gb limit?
2GB /data rest as internal sd card, system partition, cache, etc.
You can move apps to sd card if the data partition is full.
Sent from my GT-I9100 using xda premium
Relax, there's plenty of space. I've more than 80 apps installed, and they uses 664MB, so around 240 apps before memory is filled up... Remember that large games like Gameloft games installs their main data on the 12GB partition. And there is also a possibility to move most of the apps to that area as well, but it is unlikely that you need that.
The 140MB used on your phone probably includes some pre-installed apps.
Phew! That's big relief... Thanks so much. Just one last small doubt, I realized that only some apps are allow to be moved to the SD card while others like facebook have the this option greyed out. Why is this exactly?
some apps have the ability to be moved to sd card while others dont due to the way they are built..
can use device internal memory to store app data?
guys is it possible to use the device internal memory (1.9gb) to store app data in absence of internal and external SD card? my camera/apps don't run in absence of the SD card any way to get around this by using the the device internal memory? ( i have 1.5gb free after installation of all the necessarily apps)
I get that there are 3 kinds of memory in a flyer. the 8gb of system memory, the 8Gb that they call external sd card and then the user supplied SDhc card. Up until the time that my flyer crashed... I was sorta installing apps and letting them go where the pleased... and i kept on getting out of memory errors or things would not load.
When I reloaded my apps... I put as many as I could into the internal...external SD. So now it has a few hunderd mb of space left and the internal memory has about 3Gb of space open.
And none of the widgets for those program work.
My question is...how should I look at memory usage? Should I leave as much internal memory open as possible so that I can not run out of memory when using apps? Is the user supplied SDhc card only good for things like movies, pictures documents... and not apps?
When that message comes up, its usually talking about the RAM. The Flyer has 1GB of RAM and if you are running it to capacity (ie, close to 1gb), and you try to launch another program, it will not load due to the lack of RAM. In order for it to run, you will have to clear up some RAM by closing programs that are currently running. You can see this all in the task manager (bring down the notifications bar, and in the program shortcuts, you will see a program with a name along those lines: task manager or task killer). You can view your tab's memory usage and close programs that you are not using from there,
Most widgets cannot work if not stored on the main, internal memory, the default for new applications. Some apps can be moved to SD memory, but not widgets.
Hi!
I noticed a trend: whenever my internal memory is about half full, the phone starts lagging terribly. When I clean the memory (usually by deleting some blobs of misc files in the 0 directory), the phone is amazingly fast. Can anyone tell me why that is? Are we not supposed to use this internal space? Or is the problem in the type of files I am deleting, are they slowing the system down? I'm guessing this might be a general Android issue.

of course yes. no apps installed=faster phone. once you start installing and using apps, the ram is used.. you already know that. once the ram is used, it depends on how much free ram is left. more free ram=faster phone. if you would like to: root and install greenify. that would help a bit.
:good:

The problem is that I am not installing/uninstalling apps. And I mean the internal ROM space, in my case, 16 Gb, not the RAM. As for greenify, the opinions on that piece of software are divided, some are comparing it to the useless task killers. And anyway, I tried it and it did nothing for me.

all are related. the more internal space the apps occupy, the more ram is used and hence it starts lagging.

The "Internal phone storage" refers to the portion of on-board flash space set aside for APK files, databases, preferences, and other local files.
RAM has nothing to do with internal storage.Running programs (OS and end-user apps) consume RAM, but only while they are running. And RAM gets wiped on a reboot or while using task managers.
Only apps/system processes running in background takes up RAM. More apps doesnt automatically mean more RAM wasted.

that is good description. also please solve his problem if you can.
:good:
After you install an App and start using them, small secondary data files are created automatically. These files are stored inside the device and act as a cache for future use for the apps. Even though these cache files are very small in size initially, they pick up size over a period of time. Cache memory is supposed to speed up app and Android device performance. But too much of cache will have opposite effect. Your device performance will slow down considerably and also you lose lot of internal memory.
But this still doesnt explain how deleting certain files on 0 folder improve the speed ! if you could explain which files you deleted that might help in finding the cause.
Does he mean the 0 folder that 4.2 installation creates?
Only way I can see clearing space on the internal sd card would help is if you have a lot of bad blocks, which the emmc chip is tripping over on each write.
I've never used the internal sd to store anything, never had a freeze or stutter either. The two might not be linked but given the awful memory design of these phones I'm trying to avoid the problem occurring.
