[Q] Froyo 2.2 - where is all the memory?

I had read that Eclair could only access 256MB of the Cappy's system memory and that Froyo was going to be able to access all 512MB.
But I'm still seeing 80MB free after flashing to Froyo same as 2.1.
And the problem of diminishing memory is still occurring after the phone has been sitting idle overnight I'll wake it and have like 60MB free or once even worse w/ 25MB free.
Using Ultimate Juice, Adv.Task Killer And Titanium Backup(froze many unnecessary apps), but still horrible memory management on the part of Android. I was hoping Froyo was going to be better.

That was a test release, and it was a bad buggy one at that. I wouldn't put too much value in it. I would also expect that we will have more than one "official" Froyo release as it continues to get tweaked.

I was seeing 304 Mb TOTAL, of which < 130Mb was available in task manager. More than 256Mb, but still not the 512Mb expected in 2.2.

Yeah, about 300 is available with Eclair, not 256.

Let's get over it. You will NEVER see all 512MB in Galaxy S. Samsung happens to count the shared video memory (128MB) as the total RAM which technically is correct but that video memory will never be counted by OS because you can't load programs into it.

we are seeing 304 mb then we should be seeing 384 mb

Other things also need ram such as the cellular radio.

And os.

Basically theres a rather large "blackhole" of ram that is reserved for an unknown purpose. Some say graphics, some even say its a bad part of the chip that Samsung covers up. Nobody knows for certain. HIGHMEM support is supposedly already enabled even in 2.1 builds. Our only hope is that Samsung gets their act together and fixes it.

ROM not taking full advantage of all the RAM?

Allright, everyone has their noob questions and here's mine:
The HTC Inspire has 768MB RAM, correct? Yes.
So why is it that whenever I go to Settings > Applications > Running services
I see it saying 140Mb Used + 416MB Free.
That's only 556MB RAM.
It always adds up to that number.
Where's my other 212MB RAM being used?
I'm currently using Android Revolution HD 4.0 Beta 2
Thanks.

I'm not an expert but I recall someone saying it sets some side for the video processor to use.

A portion of the RAM is used by the OS, all the processes it needs, the launcher, and sense UI stuff.

True, but those "system processes" are also shown with that 556MB, and they usually take up around 200MB of it. Leaving me with about 350MB RAM if I'm running nothing.

What he says is true...on a fresh boot with nothing running i usually have between 350mb and 365mb free and the Android OS and HTC UI are in the list of whats being used.

Theres some being set aside for hardware. The gpu may use some, theres probably a good bit set aside for the radio. Like the galaxy s, some may be able to be skimmed from here and there to give a little more user accessible RAM, but I've looked into this 0%. My kernel for the captivated is able to give around 30 extra MB or RAM accessible to the user with everything still working 100%(hd video recording etc). There is 768 mb or RAM in the phone though, some of its just reserved for things that need some of it dedicated, its not dynamically distributed as hardware needs it, instead its set aside UNTIL the hardware needs it.

Not everything appears though in running lists, the launcher for example takes up at least 20-30Mb of RAM just to run. Other internal processes just aren't shown. Sense UI stuff I bet is a big part of it.

You can set your task manager/viewer/killer to show all the system processes and whatnot.
It doesn't show 768 total ram.

I have this same question about the 4gigs of storage I've seen reported... I only see 1gig myself

The theory behind this is that the 4GB has been formatted to Single Layer. When you do this to flash memory, it becomes faster and more stable, but you lose half of the storage space. So 4GB goes to 2GB. Take out for the operating system, and you are left with about a gig.
Once you format to single layer, you cannot go back. I know it sounds like false advertising, but i am fine with my system partitions being faster and more stable in exchange for losing a couple of gig. There is always SD cards.
I hope this helps.

Yup that was the same the same question/ordeal when the g2 vision came out and this was the answer that was found.

[Q] Can Cache be converted into RAM?

I recently installed root explorer in my milestone xt720 (dexter's froyo) and i found out that there is more than 100 MB free memory in cache folder, while on the other hand i am running low on memory for my apps and RAM. I barely get 30 MB free with no apps running in the background. This makes my phone really slow even when its overclocked to 1Ghz. So is there any way i can use some of the free memory from cache as RAM or as data for downloading apps? Thanks

Nope. Just nope.

Yup, FJFalcon is right. The idea sounds pretty good. If you could use the internal flash as a swap it seems like it would be much faster than the sd-card swap. But there are too many problems with this idea. First, it that would involve some sort of weird partitioning of the internal memory (which Motorola prevents on this phone -- locked bootloader). Second, on most ROMs with a clean install you get something around 70MB free space on /system and around 130MB free space on /data. So you're really looking at 200MB at most, and that's assuming you don't install any of your apps on the internal space and no cache for any programs. You COULD throw all the apps on the sd-card (Link2SD), but you'd get a performance hit there and then with no cache...ouch. It would get pretty complicated pretty quickly. So I think that's the long answer for FJFalcon's reply.

thanks alot fjfalcon and thejaycan
but as far as ive seen this phone never uses upto 100 MB cache and, using this phone for so long, it gets frustrating seeing all that space wasted!
i wish something could have been done.

What is the best way to increase internal memory for the phone?

run something besides the stock firmware. AOKP for example has a smaller memory foot print than the shipping firmware.

to be honest, you can't really do a damn thing, running a different rom will free up maybe 100mb.

I'm currently running cleanrom lite 1.0. However, I still find that I usually only have around 250 mb free to use even without any apps open.

Running ver 1.1 and loving it. I dont care if it says 5mb free. If its running smoothly thats all that matters

Your question is about increasing internal memory. Unless you were to break the phone open and replace the chip (not sure how well that'd go but I'd think not so good), you cannot increase memory. You can run a lightweight rom but that just makes more available not increasing size. Also its unclear if you're talking about internal disc space such as the ad card that you'd see on many phones, or actual memory.

I'm pretty sure he meant something along the lines of increasing the memory that's free, not actually opening up the phone. I hope..

2gb of ram?

Can someone explain this to me?

I don't know why, I have the same thing, but I think its related to how you would order a 16gb microsd and have, for instance 14.03 gb.

Some of it gets used by kernel space and video ram.

Think of this as a computer, a computer with a video card that doesn't have on board RAM will reserved some portion of the RAM for it's own used and will not show the full the full system RAM because of that portion being reserved. It's computer's nature.

Basically this.
If you look at any Android device, you'll notice it doesn't list the full amount of RAM that it physically has. It's just the nature of the operating system.
With 1.62GB reserved for use by applications, who can complain? That's equal to or more than pretty much any Android device in existence at the moment.

Bloat sucks! Like others have said, roughly 380mb of ram is reserved for the system.

Without that "bloat" your RAM wouldn't work at all.

Huh. Think about what you just said.
Bloat is by definition superfluous data that is not required. And the ram would still work, it just wouldn't have anything to run so it wouldn't have a function.
What you were probably trying to say was without the necessary required system files the ram would be largely useless. Of course that really isn't relevant in addressing what droidstyle said.

derpy derp, please refer to bobloblaw's post!

can't see the attachment in the OP, but I assume based off the comments they are noticing the 1.6Gb available to user, which is as others have explained, after all the system gets it's memory and all
then out of that, at least on my CM10 JB build, with a lot of apps running, there is still 1GB of ram free, so there's 600Mb actively in use by apps and what not....
be really glad you have a full gigabyte of free ram, you could be like the Exynos guys and get a gimped 1Gb of ram and have only 100!150Mb free, and have your apps and stuff having to reload and stuff just to maintain free memory for overhead.

Yes that is what I was trying to say. Thank you. But it is not irrelevant because by definition bloat would not be necessary files to my way of thinking. Bloat (the way I think of it) are files taking up space that are not necessary. This 380k is necessary.

the 380 is mostly necessary. you and droidstyle are both correct, no not all of that is useless stuff but honestly probably a majority of it is crap running in the background, stock apps and widgets and processes, that nobody will ever need.

LG Optimus LTE II announced the same day as the Galaxy S III comes with 2 GB of RAM. Although, if I recall correctly, the usable memory is something like 1.2 GB.

2GB of ram is quickly becoming the norm. It's nice after a couple days let say I have opened 60 apps, and when i go back to an app from the day before after using my phone the entire time, to be able to go back to that app and have it be right where i left it, having lost nothing......also it's nice to be able to run very involving launchers and not have to wait on it to reload from time to time......

Your so called bloat isn't loaded into ram unless you launch it and I'm certain it isn't using the system reserved ram but would use the free ram pool. I would assume its the os and video memory that is using that space not some vzw apps you aren't using.
