So I have a question.. our EVOs have decent hardware.. why is it we can barely handle some UI and some function when the hardware is simular? Like realistically, I think our phones could handle a lot more if we develop it a different way. Look at the system requirements of Windows... We have the basics and what not.. what's holding us back from making the EVO not even slightly break a sweat? From what I've noticed with most roms, our phones will work 90% of its systems while playing angry birds space or space consuming apps.. if we made a ROM in such a way where we can take that 90% and turn it to 20%, I think we would be doing the impossible or best possible thing.. Im an idiot in some aspects like how hones may work but I'm just trying to get everyone thinking here.. are we not that far in the tech age or is it that it would take forever to build it from the ground up not being payed?
for the most part, whatever's in the rom is needed for it to run. you can run a rom without sense if you want to save memory, but it won't look as pretty. as for trimming it down, down to what? we take out everything that the carrier puts in, and we're left with what is required for android to run for the most part. a lot of problems with newer roms is drivers. we need drivers. they won't release them.

prepare for brain hurt. as you are saying, you can strip it down, but scheduling processes, including background is still important and requires resources.
The biggest issue with the evo is its older and lower amount of ram that is the one thing its seriously lacking in. It has an older generation and lower amount of ram than newer devices. Newer devices with the same amount of ram are using a newer generation of ram which performs better than the older version, the Evo is using mobile DDR vs newer devices using mobile ddr2 or ddr3 ram which at the same amount handles processes much more efficiently making the device perform better, just like if you have 4gb of DDR ram in your PC and upgrade to 4gb of DDR 3 you will see a massive performance increase even tho the quantity is the same the quality is far better

The ram and CPU hold it back a lot. Remember, the evo launched on 2.1 and is on its third os update. Gb uses a lot more resources than froyo and eclair so the ram is all hogged up by just system services. In my opinion, the evo doesn't run gb sense very well, so of course ics roms will be somewhat limited since there will be no ota with ics and no source kernel for evo

Anyone still running Froyo on their EVO with better performance than GB? Just curious because I've often thought about rolling it back just to see how it goes for a while. Also,anyone know of anyone keeping any Froyo Sense ROMs up to date?
Sent from my PC36100 using Tapatalk 2
You can actually get a lot more out of the device if you are careful with what rom's and optimizations you have. For example, swagged out stock n barely uses resources at all. Sio scheduler reduces CPU load, noatime mounting helps a lot.
I have seriously awesome performance on swagged put stock n after i used ttitanium backup to remove crap I don't use, with sio , and smartassv2 with nstools setting all the CPU settings to the least performance settings (battery saving settings)
As for froyo vs GB, I feel like I had better battery and speed on froyo. Could be that my batteries are 2yrs old, could be netarchys old wicked kernels. I actually haven't even been on GB for the last 6mo. ICS is beautiful.

So many froyo roms in development section, but still Vibrant showing 324 (more or less) of ram available? Isn't froyo suppose to fee that part of ram up that is not being used in eclair?
I think some of it is reserved for the GPU
Sent from my SGH-T959 using XDA App
There's a thread in the i9000 section about this. The short version is that all that RAM you can't see is reserved for various parts of the device to use. The radio uses some, the camera uses some, the GPU, etc.. It sucks that that memory is reserved even if you aren't using the GPU, for example, but that's how it is. They have a kernel patch over there that attempts to free up some of it by reducing the allocations. It seems to work without causing problems, but time will tell.
So the answer to the question is NEVER. There is 512MB of RAM in the device, but you won't be able to use all 512MB for user progams ever. This is no different than most off the shelf computers, they advertise 4GB of RAM, but the internal graphics takes 512MB, and other devices in the machine often do the same thing. Would it be nice if manufacturers wern't allowed to advertise this way? Maybe. However, Samsung isn't doing anything that isn't "industry standard". IMO they should all be advertising user-available RAM rather than installed RAM, but then people would ***** that the OS takes up some RAM, so you will never make everyone happy.
I would be unhappy if I thought we needed more RAM, but honestly I've never seen my Vibrant even get close to low.
I don't mind the RAM issue as I'm not having issues (yet), what I don't like is the internal storage.
On the Vibrant it's not too bad since we have 16GB, but for something like the G2 where they advertise it as 4GB, but you only have access to ~1.5, that's just not cool!
Eventually there'll probably be some kernel tweaks or something that'll free up some of that internal RAM, but I don't forsee anyone coding for it until they actually need it themselves (nothing speeds up development more than personal interest....why do you think the dev ROMs are so much better than the Samsung ones).
Guys, how can I get my samsung vibrant to recognize all the 512mb of ram. I thought froyo has all the software and kernels and stuff to recognize the full 512mb of my phone not just 308mb. Do I need to flash a new kernel or something. I have the nero v3 rom on my phone, with voodoo enabled. So how do we fix this?
308 MB you phone is showing you is the correct amount, your phone does have 512 MB of RAM total. However, part of that is used by the phone and android system to supply your phone's graphics card and other functions such as a RAM disk if I remembered correctly. In addition, You don't want your phone to run out of memory because you are running a game and missed that all important call right? well part of the RAM is reserved to keep the "phone" portion of the Android working.
It is a common misconception that Froyo will "unlock" this hidden RAM, but in reality we are already using all the RAM that came with the phone. The reason some HTC phone shows 512 MB of RAM is either because the phone is reading the "TotaL" amount of RAM or in the case of G2 the phone actually came with more than 512 MB of ram but advertised as 512 MB (the extra RAM is used in the same way as the Vibrant, GPU/Ram disk/Android, etc).
What about the iphone, my cousin always gets 300t mb of free memory on his iphone 4. Android can't be that much of a ram hog. By the way doesn't the power vr gpu have dedicated ram for it self, I man come on, its a high end phone. Samsung is really messing up on there phones.
My question is *why* do you need more free RAM? Are you really running out, ever? Don't think of it like a PC where you need free RAM as overhead when apps start utilizing more and more. Android will free up more RAM as necessary by killing apps that are preloaded in the background. I've never run into a situation where I've run out of memory, couldn't even tell you what happens when you do. I don't use task-killers, run a ton of widgets, and I've never seen it dip below 60-70mb free.

Yes I do run out of ram. Every time I watch a flash video and while leaving no heavy ram using apps to be multitasked, after I finish my vigo and go back to my other apps I finder them killed. It gets on my nerves. I expected more out of 512mb. I also spent too much money for my phone for it to perform under shar what it's specified.

So much for multitasking, right?
Phone has 384 app accessible ram. Typically runs with ~100ish free after a fresh boot with a stock ROM. The browser can take ~30mb, so that doesn't leave much to multitasking with. When ur phone starts auto killing performance decreases. They should have h put the aeverised ram in the phone, instead of playing the semantics game. Even Verizon updated their fascinate specs to change that to 384.
I'll make sure to check this before I buy my next phone in a couple weeks tho (soooo excited!!!).

This means that this is a software issue, not hardware because the tab has the same processor found in the vibrant. 400t is allot better than just 300, not only but the tab also requires more resources with it's 720p screen.

It's not a software issue.
And yes, 100MB RAM in a smartphone is a lot.
It's like getting a computer with 4GB RAM and ripping a 2GB RAM stick out out of it.
There's 128 MB RAM that isn't accessible to the system The OS itself probably uses abut 100+ MB RAM, and once you start installing applications/services that start eating up resources.
Some say the 128 is dedicated graphics ram (fast graphics RAM to allow the Hummingbird to achieve it's faster GPU performance). What a waste. I'll make sure my next phone isn't built like a game console.
They should have at least added another 64MB RAM the way HTC did in the HD2/HD7.
The phone has as much App RAM as a mid-range Android device (think HTC Aria). It's factorable, especially if you want to multitask. Running multiple applications on this phone, I basically have to manage my apps they way I did on Windows Mobile (i.e. open task manager to FC the browser, etc.) because you don't want to be playing a game or doing anything somewhat important when the phone starts trying to auto-close background tasks to recover RAM (and some services will simply restart themselves immediately).
Good phone, bad execution in the software, and they should not have advertised it as having 512 RAM, because to anyone that isn't an idiot Graphics RAM is not synonymous with Application RAM, and 128 less RAM is quite a big chunk to be missing.

Virtually every computer on the shelf at Wally-World and Best Buy do exactly this - the motherboard graphics chip uses system RAM to operate. Admittedly does not directly correlate to a phone, and they should make a disclosure, but there is ample precedent in the general marketplace.
I don't understand why some of you attribute a free RAM amount (or lack thereof) as a memory hog?
If RAM is used instead of slower disk I/O it translates to a better user experience, the OS is good on keeping the taps on the memory and clean the thrash by itself, but nothing can prevent poor coding and a single rouge app can become the memory hog independent of how much RAM your system has, it might eat all of it.
The real problem is that the phone has only about 150mb of free ram and that'd on boot up. If the phone does have some ram dedicated to the gpu from the system ram (known as shared ram) then why
Don't other android devices do that too, and the iphone has more free ram on boot up then what is user acsesable to me. I thought the gloriose sgx540 had it's own high end dedicated ram for graphics?

Here's an absolutely healthy linux system with 2GB of RAM:
Code:

Mem: 2049868 1982076 67792 0 146988 840748

Swap: 6008824 820 6008004
I will be worried if my swap is being used a lot, but using my memory on the system is good.
I agree with this. 512 advertised, 308 seen, 150 Available after a boot....my phone keeps running out of memory so often its sad. It can never run my music player and my gps software at the same time. When I switch between the 2 apps, it closes the other one and its really really sad to see. ****ty job samsung, ****ty job. I hope the galaxy s mod gets ported for the ram which opens 338mb. At least its something.

you have a rouge app/apps running that memory hog your phone, getting 30MB of more available RAM will not save it. You need to find what is hogging your phone, I am yet to see a message that my phone is low on memory, sometimes I do a lot of browsing, txt, mytracks and playing music with Pandora or stock player at the same time and it never complained that it was low on memory to run these.

Who said that I hate my phone.I'm only truong to find out shar mashes it not recognize all it's ram. In this era, ram is a huge factor to run apps and most importantly newer os updates like ginger bread and honey comb. Don't wanna run out of ram right when you boot up your phone don't you? And if the tab can recognize more ram than this then this means it does gave something to do with software. I guess we have to wait for samsung to release froyo, because im sure that they will gave all threw tweaks that will boost this phone very high, bedside from shar I've noticed, all the,roms out thete dont really boost this phone allot. How do I know,i gave nero v3 and that only boosted me to 1137 on quadrant from 2.1 and with voodo enabled I get 1500 max on quadrant. Oclf the same thing too. so all I'm saying is that it's definitely a software issue. Pretty sure android does not hog 400mbt. And no sgx has its own ram for sure.
I still don't get how you're running out of RAM. Right now I've got Winamp streaming through BT and have started streaming a Flash video. Also running are XDA and Maps. No hiccups.

It's due to low RAM.
When there's low amount of free RAM, android will kill some running apps to free up some.
I don't really know more details, but you can tweak this behavior using RAM scripts or your own lowmemorykiller values.
I think ~1GB of RAM (like SGS2) will be really good for multitasking, but SGS1 RAM is a bit low.

Try talon kernel. It uses zram which is compressed virtual ram. You can have a half dozen apps open at once at the cost of brief lags swapping between them. I have listened to music, downloaded a 100mb file and Web surfed without any aap killing!

leaked specs of the Samsung Galaxy S3 say it will allegedly pack a 2GHz quad core into its 9mm metal and glass frame.
I'm getting me one of those when they are out.
With most new phones having 1 gig standard now, I see the new LG phone announced will be coming with a crazy 2 gig of ram. I'm no technical pro but isn't that a little overkill for a phone? I've never had an issue with 1 gig on my last few phones, and I know ram isn't all that expensive but it seems to be a marketing ploy to me.

Full scale Linux runs perfectly well on much weaker systems. If you're talking about the Linux-on-Android project, the UI is not very responsive because it's not running natively, but through a painfully slow remote desktop thing. The actual processing that's happening behind the scenes is pretty quick and so it's still very useful.
Depends what you are doing.as to how much memory you need, etc.
Screen resolutions are getting bigger, cameras are higher res, etc. it all adds up to more data to hold on to and move around. Having an extra 0.5GB or 1GB can make a huge difference in some cases (e.g. Photo or video editing on-device.)
Also, Android puts apps to sleep rather than closing them down and releasing the resources by default (only properly disposing of them when more resources are required for a foreground app. Having extra RAM means more can be resident in memory without needing to dispose of anything so that could lead to a slicker UI experience and a phone that seems really fast and responsive.
The thing that disappointed me the most about the s3 was the ram, really ruined it for me. Phones today must have 1.5gb atleast.

Using RAM is not bad; needing RAM is bad. Android 4.0 can easily run with less than 400 MB, but some things can be a little faster when they don't have to constantly reload.

One of the most frustrating parts of the HTC OneX for me was when i was reading a long page of comments on sites like the verge or typing up a forum post. If i left the browser to reply to a text or facebook notification, and then returned to the browser it would always reload a page, and at the top.
Even the (heavy) Sense 4 launcher would have to load up every now and then.

i wasn't making fun of android, i was making fun of touchwiz. too much bloat.
If the RAM will mean Nova Launcher wont reload itself as much as it currently does on my Incredible, then that's reason enough for me.
Having had the 1X for a month the 2 gb ram was one of the reasons I switched.
The 2GB of ram (and LTE) has been excessively downplayed by the International crowd because..well..they don't have it. The fact is the 2GB of ram should allow a stock phone to reload things much less. If you want to look forward 6 months to a year, I think the difference will be potentially much larger when we start to see creative devs tweaking their kernels to really use this extra ram. This is a ground breaking hardware move. We haven't even really begun to see what is possible. Judging any of these based on stock software at release is pointless. Think about how much better other phones have gotten after a few OTA updates....this device, especially with the extra ram is really well equipped for a long time.

By the time any phone will actually use 2gb of ram, im sure most of us will have moved on to a new phone already. Of course having the extra ram is good for bragging rights, but does it actually mean anything? I'll say no, but im sure some will argue that.

they already make use of 1.1-1.2GB of ram out of the box running all stock software.......imagine if custom roms/kernels were available that make use of it....it's not far off....."by the time any phone will use" is closer than you think

This is good in theory but everyone on here is talking like we have been missing two gigs all this time in our phones. If you are coming to the S3 from a single core phone of course this is night and day. My SGSII has NEVER.....I repeat NEVER run out of memory lost track multitasking or had to close out multiple apps to make room for more.....how many apps does one need sitting in a suspended state?.....I have 5 or 6 apps open at any given time with PLENTY of room for more...sure the extra ram is nice to have, but its completely unnecessary ....dual cores with a gig of ram have NO problem doing heavy multitasking .....ask anyone running as SGSII or Gnex.
The extra ram in the S3 is there to offset the loss of quadcore....its a nice helping hand to the Krait chip but not necessary for everyday multitasking that the average person does.....I don't know what phones alot of you guys are coming from but from the sounds of these posts they were serious under achievers.

i think the reason you never saw your device running out of room is likely because the system knew how much memory it had to work with and was always adjusting things to accommodate as much memory....if the system had more memory available to it it can behave differently....it's not about "how many apps one needs in a suspended state", it's about "the more apps you can keep in a suspended state the quicker the apps will run for the user"
i know this isn't x86 and it's not windows, but the analogy still stands, consider Windows 7
if you build a pc using it with 2Gb of ram it will run just fine, it will use somewhere around 1Gb of ram sitting idle, using it for the prefetch cache to be ready to launch your most used apps while maintaining a safe amount of memory for sudden useage/overhead
if you upgrade that same pc to 4Gb of ram, it will use close to 2Gb at idle.....it's not quite linear as that but you can see a direct correlation between available memory and memory utilization
the Linux kernel behind android appears to work very similarly, it will keep the most called upon code in local memory so that it launches faster when next called upon. the more memory available to the kernel, the less time it can spend killing apps in order to maintain that same level of free memory for the unexpected execution of a new app
the more memory it has, if it is written/compiled to take advantage of it, the more potential for performance is there.
I would say the 2Gb of memory is more easily utilized than the additional redundant cores in the Exynos kit. I have been looking for some real data on Android and SMP but I know recently Intel made a rare public statement about how it is not ready for even dual core utilization. I don't think Intel would make such a specific claim without data. I don't think the Exynos users are really getting much good at all from the four cores other than synthetic benchmark scores and I think they could see more benefits down the road from more memory than redundant A9 older technology additional cores.
disclaimer: I am still learning about all this so if some smart guy comes along and sees something above that is not quite right....it's not because I am making this up....it's what I understand to be true based on reading.

You are pretty spot on for the most part....but the difference here lies in the amount of ram needed to cache applications and perform extended tasks.....the reason my GSII never runs out of memory is because it has plenty for any array of tasks. While caching 8 applications I use all day...and still have anywhere from 325 to 400 megs available for any other array tasks .....I just can't see where I would need more.
As for your earlier mention of custom roms.....this becomes even less necessary ....right now a stock GS3 is using over a gig.....that's because its loaded chock full O'carrier BS on top of all samsungs layers of bloat and BS "features"....you strip all that crap out and you have a 275mb OS and more ram than you will know what to do with.
Bloat is the only thing requiring this extra ram because its running at system level which is also why Sense stuffed a dagger in the H1X.
Performance for launching is helped greatly by the processor for anything not in ram and the threshold for my phone is 64mb....which means my phone will not start killing of apps until that's met.....I could not seem to hit it just messing around.

right on, yeah i agree it's overkill right now. I just think within the next two years, we will easily see multiple areas where having more is better than having less. I am thinking way outside the box but I am seeing visions of custom kernels that are doing some extreme caching, even running a VM type environment.....actually I am thinking of running Android and perhaps there will be an opportunity to run Windows RT or some desktop version of Linux simultaneously......something a device with even four cores and 1GB of ram would have a hard time doing.....and that's not to say it would run well on the S4 US version either, but it is certainly more suited for it

You are partially right. My sensation xl and my friends galaxy note works multitask pretty well with just 768mb and 1GB ram. But that was on Gingerbread. Once we upgraded to ICS multitasking suffers tremendously. He even blamed me for persuading him to do the update. For GB 1GB is enough. For ICS 1GB is not enough if you want the best multitasking experience.

I have to blame both device and OS....I am running ICS on my GS2 and have not even seen the slightest difference.....although my battery is just slightly worse.

You must be running some early leeks cause some of my phones like the GS2 and the evo 3d are running ICS flawlessly.
