I have a " samsung galaxy player 4 ". I was wounder how much memory ( RAM ) it has ?
I thought i had 512.... but its only showing like half that, why ?
Thanks

The OS e.g. Android and Touchwiz use up about 100mb RAM for itself leaving only 300-400mb for the user. My HTC Desire S has 768mb but really i can only use 623mb hope this helps.

Is there a way to install a mod to free up some of the RAM the OS uses? Or a lighter android that doesn't use quite as much?

I would recommend a 3rd party launcher like ADW Launcher on Android market very light weight, also a app like memory booster which frees RAM. Their are no such mods to change the file system usage as changing the amount of RAM the system needs could result in a unstable device. I have a Galaxy wifi 5.0 with 512mb RAM and the 200mb left is enough for me without lag etc. hope this helps
I recommend using Advanced Task Killer. It has a very easy interface, and frees up ram quickly.
What does it say for ram on the player.... I have seen 377... and 345.
I have 345 and Im pretty pissed about it.
I have 342mb of RAM available. But I heard that around 100+ mb are dedicated to the gpu on the galaxy s phone, and the galaxy player has the same hardware so should be the same. So I think it still has 512mb of ram, but just 342 is usable by Android.
Have a look at the output of dmesg (e.g. run the following in a terminal and copy the resultant file to your PC to view: dmesg > dmesg_output.txt) and it tells you how much memory you have and how much has been set aside. Note you will probably want to reboot before you do this as otherwise the interesting messages have scrolled out of the kernel message buffer.
I've been using an app called Fast Reboot Pro. It appears to simply close processes that are running in the background. It then shows you how much memory was was freed. I hit every so often and especially when things appear to lag. Seem to work pretty well.

Gingerbread/Samsung has it's own task manager which in turn has it's own widget which does this. No need to install an app for this
I to use fast reboot, find it much more effective than what the player comes with. I also use ram manager pro witch is a very good tool to set different ram profiles, I like "balance (more free memory)" the best. I first select my profile, then I run fast reboot, very effective! The more you run fast reboot, the more memory it frees up, witch is great for big games like asphalt 6. Also, I use zeam launcher, very lightweight, perhaps the lightest, but still a great improvement over touchwiz. Another thing, NO LIVE WALLPAPERS is an absolute necessary! These things eat WAY more ram than they say on taskmanager. THEY CAN EAT 50+ MB OF RAM!! Also, services like widgetlockscreen and such will eat your ram. If you want to play a heavy game, go to running services and kill as many as you can, you can also clear cached apps by hitting the menu button in running services. Hope these tips help you to make the most of our small supply of ram!
Hmm, after more testing, it would appear that wifi burns around 25mb of ram when on! So, if your really short on ram, just turn on airplane mode to kill all antennas. I just played modern combat 3 with 25mb free ram throughout the whole level I had 190mb free originally, that game sure eats the stuff :s The CPU rides at 1000mhz through the whole game, lol, could always use some more of that stuff! That's what oc is for
I'm running dagr8s alpha 2 ics rom. And I know that it has lower ram than the gb roms. But lately I have been running Tasker (amazing app btw) numbers and it keeps notifying me that I have low ram and it might not work properly. I go to applications in settings and check my ram and it says I only have 98mb free. I end all tasks and clear ram and then still I have like 120-130 free. I'm afraid that this is a too low amount. And wanted your opinions on what I should do. Is this enough should I just ignore the warnings will Tasker still run fine? How can I get more ram? Are any of you also experiencing low ram?

Taller uses ram also. I run trebuchet launcher on alpha 2 and have no real issues. If it gets slow you can hold home and clear things out. Running a lot of widgets still affect ram also.

If you go to developer options in settings at the bottom and select the background processes and set it to 3 processes at most that helps alot...also if u change ur dalvik heap to 64 that also helps a ton...DO NOT and I repeat do not set it below 64 as u will soft brick your phone

You must understand how Android uses memory, it loads your frequentlyused programs into ram so when you go to use them, they open much faster than if they would if they had to open "fresh" each time.the lmk (low memory killer) should take care of everything if you ate currently using a process that uses a lot of memory it will kill off apps as it needs to.
Put simply: FREE RAM IS WASTED RAM.
Have a marine navigation program "Navionics USA EAST" that wouldn't open in ICS(leak and Saurom) unless I cleared RAM. No issue onstock GB, and runs fine on sgh-i777 ICS? Tried debloating leak, but didn't help much. Will try limiting running programs when back on ICS.

Free Ram is wasted ram. Never thought about it like that. I understand but i would still like some free ram just so its available for other apps i open. I did use the task manager to kill running apps and clear ram and it didnt free up that much ram that is why i was worried.
Ill try limiting background proccess to .
Also how do i set dalvik heap to 64? And what exactly does this accomplish?
Thanks for the replies guys.
Yes set it to 3 processes at most. Task manaher killers r just crap dnt use them

Welcome to ICS. This is exactly why I DONT like ICS - the memory footprint is huge just for ICS alone.
Free ram is not entirely wasted ram.
Let me explain.
So, my phone RAM is completely (or nearly) filled and I open a new app. There is now a long delay as Android goes to work closing app(s) down and doing garbage collection to free up memory for the new app I just tried to open but it only frees up enough for the one app I just opened.
And now, every app I go to open is going to have this long delay.
What you really want is about 80% ram usage - enough that there is free ram to open new apps without Android having to scurry around to free up a bunch of memory.
I dont know if there is a way to force a certain amount of ram to be free but imo, thats what youd really want.
I only have 6 user apps on my phone and Im running stock GB so even if I opened everything at once, there would be plenty of ram to have them open all at once (Go Launcher, Blue Skies (paid), Battery Power Widget, System Tuner Pro, BeyondPod, & Audible).
It's called "minfree memory," what you want is an app that will allow you to modify those values. Back when I had a Captivate, I used an app called AutoKiller for that purpose. I haven't needed it on the Note though. You can find it in the Android market.
Is it possible for apps to crash when the phone doesnt have enough free memory (RAM)?
-Once you go NOTE, you'd say 4 inches a Joke
How much RAM do you guys have available when running GB. The phone only sees 767Mb of RAM out of the 1Gb is that normal?
yea i think thats normal because the phone system uses some of that ram to make the phone work. Like if you ever had a sd card or an ipod that was say an 8gb ipod you actually only have like 7.66gb free.
But yeah I would like more ram availabe so the phone can load apps quickly and wont have to waste time closing stuff. I dont think free ram is wasted ram
As said before, Android uses ram differently since it based upon Linux. If the entire ROM runs around 600-800mB and most of it gets loaded into RAM, this will leave you with 400-200mB free RAM but the entire OS is already loaded and ready to go! Once you load a RAM intensive application, Android/Linux kernel will free space for that application.
I believe GPU consumes an excess of RAM to handle this beast's resolution/size.
I have to go back to GB. Delay in apps opening is getting old compared to i777 daily driver.

Thanks for the info, guys.
I am running omega Rom v13.and siyah kernel 1.5.3
I always observe my task manager and observe that my ram usage cannot higher then ~700/833MB?
It kills my apps if usage is higher then that.
I mean why? I should be able to utilize all the ram to right?
Sent from my GT-I9300 using xda app-developers app
You only have this much ram, the phone needs its own ram for graphics, buffers, os etc. You can get more ram from siyah kernel using swap but this has disadvantages

I am not referring to the available ram.
Yes, I know system reserve some of the ram which left around 833MB for user.
and with touch wiz and other background process holds the ram, I see roughly 500/833 left over.
Now the left over is my ram for my advice apps, isn't it?
This is my question now :
The left over ram which around 333MB, I can't utilize all, I can roughly use up to 200 MB, and if over, my apps start killing
.why I can't utilize all of the left over ram?

Android its based on linux which hates to leave memory unused, it therefore uses free memory ssh buffer cache to speed up I/o.
Found this, you can run free -m from a terminal emulator

Im using pacman 18 on my neo v (JB rom)
Never really had a ram problem untill lately, when i started using viber, whatsapp, swype...
Now phone is struggling, there are no cached processes and almost no memory free.
By default zram is using 18% of my memory.
I dont exactly know what is zram, googling didnt help.
If i understand correctly, there are 2 scenarios:
1) It compresses data that would be in memory anyway, so you gain more ram, at the cost of having to compress/decompress evey time.
2) Apps that would normally be killed, are kept compressed inside memory, for faster access, at the cost of 'live' memory.
Could someone please clarify this for me?
well i dont know many things either.
I just think of this as that:
there is a swap/page file in ram that compresses useless/unused apps in ram.
Something like NTFS compress ability.
if you are using windows you have probably noticed that in the properties menu it says compress file to save disk space.
Well it just compresses it in ram and when you will need it it will be decompressed.
That way you will have more ram but maybe lags when swiching to apps.
I dont know anything about pacman rom so i can tell you about your problem.
try deleting zram (it will probably be a script in init.d)
I know it compresses data in phone's ram.
My question is, where does that data come from?
1) If that data would be in memory anyway, and they are just compressed, it gives you more memory, at the cost of performance
2) If they were outside of memory, and zram puts the in memory compressed, you lose ram, but you gain performance.
Let me also rephrase:
If i disable zram, that data that it compressed, would still be in memory uncompressed?
Or they will not be kept in memory any more?
Sorry, my English isnt helping on this one...

From Wiki
"zRam is an available feature for certain distributions of Linux, that was previously called "compcache". It increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive. Since using RAM is faster than using disks, zRam allows Linux to make more use of RAM when swapping/paging is required, especially on older computers with less RAM installed.
Even though the cost of RAM hardware is relatively low this feature still offers advantages for netbooks and other lower-powered latops, virtualization and in the case of embedded devices, especially those that use flash memories that have a limited lifespan, dependent on write-use and thus wear out quickly when used as a swap device."
So the data are still in RAM but compressed...yes if you disable Zram they will be still there but they will use more ram! You gain more free ram when u use Zram but your CPU load is higher so perfomarnce is almost the same..

Still not clear.
On linux, after ram is depleted, data is coming from page file (hard disk)
How does zram work?
Does it pre-occupy that space in ram?
Or when ram is depleted, zram is automatically enabled and it starts compressing data???

Read again the part from the wiki..it says that zram uses "a compressed block device in RAM" so yes it pre-occupy some ram like a swap file! Also read this http://forum.xda-developers.com/showthread.php?t=2023568
Hiya, when i play a game, PowerAmp and other music apps gets killed, here's the error message PowerAmp gives.
Poweramp was killed
Poweramp has detected it was killed during an active playback, probably by some battery saver, task killer, etc.
Please disable such optimization for Poweramp and Poweramp full version
Unlocker (botch can be killed together) in the apps settings
all help appreciate
Add some GB of RAM.
This never happened before though, all i have changed since is, changed the launcher and the new launcher uses even less RAM :/
Also, as far as my knowledge, you can't add more RAM to a Amazon Fire 7

You always can use a certain amount of internal storage memory as SWAP memory ( read: virtual memory ). More info here:

Yeah my phone isn't rooted though, and i won't root incase of bricking my phone :/
This seems good though
SWAP - No ROOT - Apps on Google Play
Create SWAP file without ROOT.
play.google.com
Hm, does that just create a swap file? or does it actually work?
IMO phone's Android must be rooted to set up a SWAP file. Reason is the SWAP file must get added to Android's system file named /fstab in order to get mounted when Android boots up. And operating on Android's system files requires root.

Yeah, it's a shortage of RAM. The Amazon tablets are great values but with only 2GB of RAM, it often kicks background processes out of memory.

1GB RAM on mine
although before upgrading to new launcher, it never did this before, and i found out the new launcher uses less RAM than the old one :/
