Memory swap... Dev please explain this. Necessary? - T-Mobile Samsung Galaxy Note II

OK so I have a question, and I'll just ask it flat out and hopefully somebody can shed some light on this.
What is the point of using memory swap on this device? It already has plenty of RAM space. Isn't memory swap ideal only for slower devices that don't have a whole lot of RAM? I see absolutely no point in doing this on the note ii. Your SD card is wayyyyy slower than your RAM disk, and it just puts more wear and tear on the SD.
Can anybody explain why everyone seems to be doing this? Just doesn't make a whole lot of sense to me technically.
Thanks

You will have more space to install more apps specially if you download all those games with the large files.

[Q] Can you increase the data.img on evo to 1GB data storage?

ok just got a evo and thinking of making the switch officail from tmobile hd2 now on the hd2 android roms you can increase the data.img size to default 512 MB, 1 GB or in some cases 2 GB allowing you to install more apps on to your phone, I was wondering if the same thing was possible to do with the evo I like to have a lot of apps on my phone so if someone could point me in the right direction i would really appreciate it.
11 views and not one answer seriously someone has to know the answer to this and yes i have searched and found nothing
Forums are kind of dead on the weekends.
I haven't seen anything like that for the evo since it's 512ram/512rom.
We have apps to sd - basically you can move your apps to the SD card, which is normally bigger than the ram/rom.

Um, isn't it 1GB ROM + 512MB RAM?

Obviously you can't increase it its the built in Rom space.
You can use apps to SD (a2sd) on some roms that partitions your card and puts apps on it.
yeah sorry about that and I just know on the HD2 android which I have been using on tmobile you can increase the data.img size up to 1 GB which allows you to install way more apps on your android

that is because on your HD2, the data.img file resides on the memory card, which is likely 8GB or larger, so that increase in size is possible. On the Evo, the data.img is stored on the internal ROM, which has a physical capacity of 512MB, so we have already reached the maximum capacity...
if you wanna install a lot of apps i would recommend fresh rom's .i got 330 apps installed in my phone not on my sd cz for some reason my cheap ass 16gb card act up evertime i put an app in it.

Is your 16gb card a class 6? If not that's probably why.
^ FAST... Why do you say that.. Just curious because I was about to pull the trigger on a Class 6 16GB right now.

Those are the correct specs. They are the same that HTC, Sprint, and now Google have always advertised. 1 GB Rom and 512 MB Ram.
As to the OP, you may be able to change the partitions some, especially if you clean up the system partition, but it would require building a new ROM and flashing it. At least, that's the only way I know of to repartition your NAND.
Oh, and you probably won't recover way too much memory to the data partition. Probably no more than you free in system by removing some unnecessary built in apps like Quickoffice.

Becasue a class 6 card will be faster then a class 2 or etc.
I know this is an old, dead thread, but if someone is searching and comes across the OP's question, here is the answer.

[Q] Memory Shortage

I don't know if anyone else has noticed this but on the internal memory of my E4T it only has 12GB of available space instead of the advertised 16GB. 4GB may not sound like much but I could really use the space and am trying to hold off on buying a microSD card.
If anyone can help with a solution or give me an answer on why this is it would be greatly appreciated.
Thanks!
I believe it's a norm to falsely advertise storage space in GB now. Our 16Gb is actually 16000mb, which equals to 15.625gb.
2 of that is partitioned as System Memory. If I am not mistaken, the OS takes up the balance.

Bingo. They advertise the unformatted capacity.
And its not just Samsung... Take any flash drive or SD card, or even hard drive, and compare the ACTUAL free space with the advertised capacity. It will always be lower, sometimes significantly.

[Q] Internal Memory

Hi Just got my samsung captivate glide from ebay it's a second hand phone I just notice that my internal memory is only 3gb (used root explorer to see it). Is this the real memory or there is something bogus on this phone that i got from ebay. Thank you would appreciate any reply

Lol, no it's the real phone. I actually just got mine too. 3.75GB available for me to use.
It's weird though. I had the old Captivate which had 16GB of space and more than 13GB of it was available to me. I know you lose some space when formatting but I expected to have at least 5GB with this phone. May be due to partitioning of the device from the factory. Hopefully I can free up that space, because I'd like to have it...
Maybe someone else can explain the ROM breakdown a little better

Thanks for the reply yeah was thinking looks weird they say 8 gb I know 2gb goes to system but where is the other 6 or 5 lolz anyway thanks was worried i got trick by the person I bought from.

Memory manufacturers are allowed to define 8GB as 8000000 bytes. Given this information a computer would see 8000000 bytes as 7812.5 MB or 7.629 GB. And this is before it is formatted or partitioned. Figure the phone has 7.5 GB. Then you have 2GB for internal apps and 4GB for internal sdcard. Leaves 1.5GB some in partitioning and rest in ROM use for operating system and reserved places for phone and modem sections.
That is why you hear about many people adding large micro sd cards and switching internal memory with external memory.

I have a 16gb card, and never needed a new one since... Every phone I've upgraded to has more and more built in memory, so it's kinda left my memory card the same over the years.
reply your question
use this programe for move installed data on internal sd to external
GL to SD v1.9.9
Use Link2Sd

if u want a better understanding of how your space it being used by your phone..
use the application called link2sd
and in that go to menu and storage space
it should show you all the partitions
they will some up to 8 gb i think . so there you go

Free memory?

How much of the 3gb memory will be available for use? Nexus 10 announced to have 2gb, but after buying it I realized actual available memory is 1.1gb. So, the question is, will same do the same thing?
Any ideas?

Are you talking about ram?
If yes, maybe 2.3-2.5...
For example, HTC One have 2 GB of ram, but you can use 1.5.
So, we have to see when the tablet is released
The purpose of having RAM in your phone/computer etc is to increase performance. You don't increase the performance by leaving the ram free. You use it.
Free RAM is wasted RAM
i think most people here should understand that if you're not using your ram then it's wasted. but i think he wants to know how much is available to apps after the gpu and system take their share.
someone posted a screenshot in one of the threads and i thought it was somewhere around 2.3GB.

Good, 2.3 GB
However, you're right.
People didn't understand that ram will be full..
Every one will kill all process ._.

[Q]Any way to swap external memory to internal?

Hey guys
Im looking for a mod to swap my 64gb microsd to internal memory.
Is there any way to do this?
I've tried existing mods and app but nothings happened.
Thanks for guiding me.

why don't you use folder mount? is an amazing app!
Why???
I just don't understand why anyone in their right mind would want to swap fast internal memory for slow external memory.
External memory will always be slower than internal. I have over 300 apps and half of my internal storage space. As for my 64gb sd card, I have 54 gb used in mp3 The rest is for uploading movies and photos.
No issues with app speeds and video and audio playback.
Well gooberdude, it is possible to get pretty darn quick UHS-I cards now. With a USB 3 port and adapter, mine is darn fast for like $25 off Amazon's gold box. Problem is how fast the actual slot is lol.
In some products it can actually be better to do a swap. On the old Transformer Prime (TF201) and perhaps many Tegra 3 products, the flash chips are so crappy that even a good external card and some duct tape (to keep it in) can be a performance improvement. I've not seen a Samsung device use such crappy storage but then again, I've only used Galaxy S and Galaxy Note, not their budget fair.
In regards to the OP - rooting your tablet and using FolderMount as gooberdude suggested, it is a far less involved procedure. It is best if you just want to move some stuff from internal /storage/emulated/0 (aka /data/media, /sdcard, and /storage/sdcard).
Towards a real swap, it is usually possible by modding your system to think the external is the internal and doing some appropriate partitioning/data magic wand waving. This is an involved enough process vs what the typical PC user understands how to do that I generally DO NOT RECOMMEND unless you are a developer and comfortable building Android from source, hacking the source, and flashing code. In which case, you can also use Google and find out how to do it and how Android handles mounting file systems. Hint: look at Sony and ASUS mods.
