[Galaxy S I9000 Android Development] drowne:
any improvements if we set an higher value for dalvik heapsize?
[Galaxy S I9000 Android Development] flypubec:
This is the max heapsize for a single VM...meaning

the single application can allocate max of 48Mb heap before it gets out of memory.

This has nothing to do with RAM reservation
[Galaxy S I9000 Android Development] hardcore:
No its not the dalvik heapsize. Changing that value doesn't give us more usable RAM.

I'm wondering about the Tab too. I was playing with a prototype and it definitely had more accessible RAM, as one poster said - more than 400MB. Would be good to see the dmesg boot log from a Tab to see what the system reserved and total memory is.
[Galaxy S I9000 Android Development] mtoneman:
According to this:

http://xdaforums.com/showthread.php?t=792512&page=11

there are one 2GBit (256MByte) and 2 x 1GBit (128MByte each) RAM chips totalling 512MBytes on the board. What we need to find out is why the kernel is reporting "Memory: 80MB 256MB 128MB".

i.e. what happened to the 48MByte on one of the 1GBit modules.
[Galaxy S I9000 Android Development] MCOGW:
I don't think it's that easy to (really) modifiy this value. I think you need a JTAG to modify this because these are direct parameters for the (smdkc110) chip.

So how did you manage (and verified) this?

If you would have read this thread:

You probably have read this:

Ok it is not directly a "blackhole", but it is reserved.

The SGS kernel config tells you a bit more for what it is reserved:

CONFIG_ANDROID_PMEM_MEMSIZE_PMEM=16384
CONFIG_ANDROID_PMEM_MEMSIZE_PMEM_GPU1=8192
CONFIG_ANDROID_PMEM_MEMSIZE_PMEM_ADSP=1800
...
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC0=12288
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC1=1024
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC2=12288
CONFIG_VIDEO_SAMSUNG_MEMSIZE_MFC0=32768
CONFIG_VIDEO_SAMSUNG_MEMSIZE_MFC1=32768
CONFIG_VIDEO_SAMSUNG_MEMSIZE_TEXSTREAM=10240

16 (16384)

+ 8 (8192)

+ 1,75 (1800)

+ 12 (12288)

+ 1 (1024)

+ 12 (12288)

+ 32 (32768)

+ 32 (32768)

+ 10 (10240)

112 mb

And 48 mb are not in the mem map, so 112+48 = 160

512-160=352mb

but we have a total of 325 mb (jm8)

352-325=27 are still missing

Have a look at /proc/iomem for these 27mb yourself.

And by reading that:

http://xdaforums.com/showpost.php?p=8350492&postcount=126

jpk is only missing 32 mb = gpu.

So everything is fine on the ram amount, nothing to worry about.
[Galaxy S I9000 Android Development] mtoneman:
Ok I just read up on the other threads (sorry missed those initially). If I understood correctly, the radio is separate and not visible to the linux kernel (unlike the other "reserved" blocks). This probably amounts to the 48MBytes we are not seeing in the Linux dmesg output.
[Galaxy S I9000 Android Development] RyanZA:
Total guess: the difference in free ram between SGS and the Tab is probably that video ram for the SGS comes out of the system ram, while the Tab probably has a dedicated framebuffer+ram for it's graphics, probably because it's required for the bigger screen.

Why does Froyo have less available ram than Eclair though (hardware is the same)? In fact, why do different Eclair versions have different available ram? Is this just tweaking, and if so, can we not tweak it ourselves?
[Galaxy S I9000 Android Development] brunes:
Cause it is a different OS? With more or newer components taking various amounts of memory?

This is like saying "why does Windows 7 leave you with less available memory than Windows XP". Ummm because it is not XP.
[Galaxy S I9000 Android Development] Oletros:
Mmm, and why on Nexus one there is the same RAM available in Eclair and Froyo?

And Windows 7 shows exactly the same amount of total RAM available as Windows XP.
[Galaxy S I9000 Android Development] xan:
burnes,

You are wrong.
[Galaxy S I9000 Android Development] RyanZA:
The 'OS' is Linux! It's always important to remember this. Android is just an ecosystem (a number of apps and services) running on top of stock linux. Just because Android has gone up a version, doesn't mean the underlying system has changed! Any changes to Android components are actually all far outside the kernel, and will use up the same ram as other userland apps.

The reserved memory has nothing to do with Android, and has everything to do with the hardware drivers. Since the hardware hasn't changed, the question is why the graphics and low level drivers have been allocated more ram in Froyo than in Eclair.

Possible explanations are that Samsung gave more ram to graphics to help with... something? Maybe OpenGL ES 2 needs more ram, and performs worse than OpenGL ES 1, and so the OpenGL ES 2 driver needs to eat up more ram now? Or the Froyo drivers might just be badly optimized. In any case, it seems like we can tweak this stuff, because Samsung can tweak it.

The question is, how do we tweak it? In the kernel video drivers? Are there open specs available that we could use to work it out? And more questions I can't think of... :)
[Galaxy S I9000 Android Development] xan:
Well actually comparing dmesg and iomem outputs from JM8 and JPK would answer a lot of questions.

Speculating is leading us nowhere.
[Galaxy S I9000 Android Development] MCOGW:
I think a very deep look at this http://opensource.samsung.com/ (and a search for "GT-I9000") would answer lots of questions (only for Eclair atm)...

[EVO 4G Q&A, Help & Troubleshooting] exek215:
Quick and simple question as it is not in search (or I'm wording it wrong)... I use app 2sd and put any apps that can be transferred to the sd. I recently had to hard reset my phone. Prior to that I had like 250 apps (too much I know)... Now I'm adding new apps to the phone which were previously saved to my sd... When apps 2sd asks if I want to put those apps to my sd, is it adding ANOTHER copy to my sd? Or replacing it? (which would make sense)

Also I'm not reinstalling all 250 apps from before, so how do I clear all those unused copies of old apps that are still on my sd, or were they erased when I did the hard reset...

I got a crapload of apps that need to go to the sd but don't wanna transfer them until I get this straight...thanks a million for the help

[HD2 Android Q&A, Help & Troubleshooting and Genera] thehumble1:
My HD2 was running fine on several versions of Android, currently mccm v1 SE with 2.12.50.04 Radio on top of Stock WinMo with SPD whatever thing.

I have a 2GB and an 8gb microSD. the 8gb holds my stable mccm v1 SE and the 2GB is for testing other builds.

I wanted to speed booting to Android, so downloaded chuckydroidROM and Excellor boot loader (v2.1).

I installed the boot loader and it ran fine with my HyperDroid 1.6 build.

But then, after about 3 minutes. The phone reboots to T-Mob welcome screen. It doesn't load WinMo either, unless I reboot manually with the battery or reset button.

I've been looking and looking on the forum and can't find someone with similar circumstances.

I've tried my stable 8gb microSD card with the mccm v1 SE build on it and I get the same thing.

what I've tried:

-"hard" reset (Up/Down volume button reset) = same + lost SPD mobile

-Changed radio to 2.15.50.04 (yeah, no good) = same + no signal

-installed chuckydroidROM = same

- uninstalled EBL = same

- reinstalled EBL = same

- stomped and yelled = same.

Any help? either a thread that I missed in my search or some other things to try?

Thanks guys.
[HD2 Android Q&A, Help & Troubleshooting and Genera] JanssoN:
Hmm sounds strange.

But I think you have to start from the beginning. :o

At first, what version of HSPL do you have installed?

Maybe just try another one, mine is currently 2.08.

Then you should do a task29 before you flash the WM-ROM again.

I recommend also flashing the 2.14 radio.

After finishing these steps prepare your SD. Format it with the formatting tool found here: http://xdaforums.com/showthread.php?t=748961

I would do this 2 or three times.

Then do a fresh install of your android build. Just set up as normal.

If you want to, you could try to restore your data.img. If you do that, it has to be a build from the same developer.

Try and report back.

Cheers
[HD2 Android Q&A, Help & Troubleshooting and Genera] thehumble1:
thanks for the reply. I updated to 2.14 and went with a stock 2.2 build (Nexus One). It hasn't crashed since, but I'm afraid to go back to my mccm build. I also am kind of worried that it had something to do with Excellor on the device. Of course I can't resist trying again

I'll try my original build again. I do know that I formatted the SD card well before installing this build, so that might be it. I didn't have the program though, so thanks for the link. Also I didn't look into task29, so I'll read up and find out if that might help.

I am running 2.08 too and was then. I did reflash it though.... but I don't think that was when it started working again.

I didn't know that data files may be portable if from the same dev. that's nice to know. Thanks again for the help, it's a lot easier to work through fixes with the help of a few other brains.

I am having a huge problem mounting my Epic 4G to my Mac. When I select Mount USB, nothing happens. I have read several posts about Galaxy S phones having the same problem, they all say to have USB Debugging turned on, but mine is on and still can't mount.

Also, another huge problem. I connect my phone, then I use adb to access the sd card, but I can only use adb for a short period of time, then it disconnects itself, then I try to run adb again but it does not recognize it. I have to unplug the phone, then plug it again.

Does anybody have any idea why this is happening or how to fix it?

Note: I can do everything perfectly fine with my Sprint Hero

Dude, welcome to the club. Since i got my phone i have not successfully been able to have it read on my Mac Mini. Tried different cables and different ports. Some say get a powered USB hub but i'm not in the mood to clutter my puny desk space.

[Epic 4G General] herbthehammer:
I don't have any problem with 10.5 or .6

I can use either regular or debug. Sometimes rebooting the phone and/or the computer helps. It could be a crappy cable. I don't think the supplied one is very good. The one I use with no problems is the overpriced 3 footer that the corporate sprint stores have. I think the cables that came with the epic, moment, and evo were el cheapo. I had a problem that you are describing with a stock supplied cable. I figured out that the micro usb end wasn't making solid contact with the phone. If I would move the cable, it would disconnect. Changing to a real micro usb cable helped me. It could be the usb port is flaky or the usb plug is intermittent. If you are using vmware fusion or bootcamp or dual boot, see if it drops connection in a different os.
[Epic 4G General] JGeZau:
No luck under Windows7 (running with Parallels Desktop) either. I'll try buying a new USB cable and see if that works ... Will try Websharing too.

[Epic 4G General] blazinazn:
Did you put your phone into debug mode?

I found that trying different USB slots on the PC, it will eventually work. When you plug it in the first time, it will install some needed drivers ABD etc, if you unplug the phone and plug it back into the same USB slot, it will install the last remaining drivers and you should now be able to see the phone.

Samsungs drivers are flaky at best. It took me a good hour to get it working for me so I could root my phone.
[Epic 4G General] JGeZau:
That worked, turning on USB debugging and switching to another USB slot. But, this is at work under WinXP. Now I need to make it work under OSX at home.

[Epic 4G General] Wellington Amaral:
temporary fix

This topic has been discussed at another tread.... but anyway, The Macs (current generation only) do not give you enough energy at the USB to power the phone into connecting the memory card. Nor even enough to recognize the phone for more than a few seconds. You can get around it, temporarily, by connecting through a powered USB port. Tetheris still doen's work, but at least you can mount your sd card. It's a software issue... if you're running Windows on the mac machine, it'll connect and mount fine. So, ask Mac for a fix.

For anyone who was having a problem with certain builds not having all the voice search voice actions like "listen to" or "send text", this is because these extra actions only work when locale is set to united states english. If your build does not have this locale choice, you get it from the more locale app which is in market. First uninstall current Google search & voice search then download more locale 2 and set to united states English and re-install Google searche & voice search. It worked for me so try it out and see.
[G2 and Desire Z General] pmstc:
Hey, I was wondering if anyone else was having a problem with sub par battery life. I have not been satisfied with my G2 battery life, I only get about 12-13 hours and I am not a really heavy user. I have disabled wifi, bluetooth, gps, cell location, and syncing for everything but my gmail and exchange (set to push), and it didnt affect my battery life at all.

I noticed that "Android System" was taking up 35% of my battery, which I am pretty sure is not normal, so I decided to try a different battery monitoring app to get more details. I downloaded PowerTutor and it was showing that Facebook was using a LOT of battery life over the period of about 10 minutes, which was strange considering that I had turned off all notifications, turned off the refresh, and turned off syncing. It shouldn't have been doing anything.

I logged out of the facebook app and it no longer seemed to be doing anything. My facebook version is 1.3.2. Hopefully this will give me some better battery life (right now i am at 24% at 3:00pm after unplugging at 6:30am, but PowerTutor ate a good bit of battery life while it was monitoring)

Just thought I would post for people who might have abnormally low battery life, and see if anyone else had the same problem.

The facebook app is terrible anyways, I won't miss it. I just use a shortcut on my home screen to m.facebook.com

I'll post back tomorrow and see if my battery life has improved.
