[Samsung Galaxy Tab Plus] h2g2:
Just to be clear, I have no real stake in this except to make sure that the technical facts about the swapfile are presented properly. In much the same way that you've been frustrated hearing about people recommending that they disable kernel panic reboots, I also am frustrated when people have a knee-jerk "swapfile = terrible" reaction that is largely based on FUD.

That said, you're right, I should just test it myself when I've got some free time.
[Samsung Galaxy Tab Plus] h2g2:
Dusted off my old Nexus One, loaded up a clean install of CM7 and installed a kernel with CONFIG_SWAP=y. I decided to go with a swap partition on my sd card rather than a swapfile but the effect should be the same.

I haven't had time to do extensive testing but so far but I can confirm that swap is working and I haven't yet noticed a major perceptible impact to performance of the device.

Been switching back and forth between apps for a while now, paying particular attention to apps like Google Earth and the Browser that load up lots of data.

One particular test that seemed to stress the memory subsystem was using the "Print this page" on multi-page articles on graphics-heavy sites like, e.g. Anandtech (had the Snapdragon S4 review up). With swap enabled, there was a delay of 1-2 seconds when switching back to the browser (no doubt from reading the appropriate pages back into memory) but without the swapfile, the session was gone and the page needed to be reloaded, which took much longer than 1-2 seconds.

Some caveats:

1) I used a rather small swap partition (64MB) compared to the amount of memory available on the device (512MB for the N1). This means that I didn't need to do too much tweaking to the lowmemorykiller settings.

2) I set swappiness to 100, which is intentionally a bit heavy-handed (default seems to be 60).

3) I did not tweak other settings such as dalvik.vm.heapsize, vfs.

_cache_pressure, page-cluster and, as mentioned in #1, lowmemorykiller/parameters/minfree.

[Samsung Galaxy Tab Plus] danielkaboom:
little of my understanding, if a swapfile is made in an external sd, the sd card must have good r/w capability (minimum required a class 6 sd card), what if the swapfile is made in internal sd (since GTab have 12gb planted chip memory), what is the effect?

and so,....would you be kind enough to build a kernel for GTab 7+ that support swapfile? and if you do, can you do with a flashable zip (which i can flash it through cwm recovery?

so i can answer my own question : swap or not to swap?

and of course if you have spare time

thanks

dan
[Samsung Galaxy Tab Plus] h2g2:
I'm using a Class 2 8GB MicroSDHC card from Sandisk on my Nexus One for testing and it seems to be fine. I'd recommend using an external SD because it's replaceable and swap I/O will wear out your flash faster so you're better off segregating it.

I took a look at the state of the kernel source for the GTab7+ at the moment and it looks like the Samsung sources are out of date and a kernel built from the current sources won't run properly on the LA3 firmware (Garyd9 notes this in the thread for his kernel as well) so right now, building a custom kernel is a nonstarter for me because the LA3 firmware fixed some pretty major shutdown issues for me on my Tab.

Perhaps when the ICS sources are released, I'll take another look.

[EVO 4G Q&A, Help & Troubleshooting] Dratini:
Someone tried to steal my phone while I was recording a video, when I got it back, the screen didn't turn on. The backlight works when I turn it on, when it boots in, the backlight turns off and the screen remains black and the buttons light up, pressing the power does nothing when its on (the buttons remain on).

Not sure if it can be fixed or if its just broken.
[EVO 4G Q&A, Help & Troubleshooting] savoca:
This happened to me a few times, just pull the battery, replace and reboot. If it boots into that screen off phase plug it into a power source, and if it still doesn't light up then leave it off for a few hours, could be an overheat. If all that fails then you may end up on the toilet giving Sprint a ring.
[EVO 4G Q&A, Help & Troubleshooting] Diablo67:
Could be a corrupted battery,you can try pulling the battery and plug the phone into the wall and try turning it on.
[EVO 4G Q&A, Help & Troubleshooting] stevovanburen:
Hey,

Pull an Andy Sandburg and throw it on the ground! then take it to sprint and have TEP replace it ;) lol

just kidding, yeah it sounds like a hardware issue of some sort, like they said try a different battery or see if pulling it and trying to boot makes a difference.

When booting hold volume down as well as the power button to see if you are able to boot into the bootloader.

If neither of those things work I would say its the screen or in internal component man and you will need to take it somewhere to get evaluated and fixed!

Good luck!

I hope I helped If I did please hit the thanks button!

I tried different batteries, and unfortunately it seems to do the same thing. I opened it up and I'm almost sure there was some sort of internal damage, but I have no idea what it was.

Its such a nice phone, I am gonna be so sad if it doesn't work. I'm putting it on the charger right now with a dead battery. I hope it works. If not, I have a very expensive HTC battery charger... :/

Its been broken for like a few months now, so I don't have much hope, but if it works then I'll be happy.

[Atrix 4G General] fjhuerta:
I have 3 different Android devices: a Nook Tablet, a Samsung Galaxy SII and the Atrix.

The Atrix is the only device I have OC'd and added a custom ROM. The other two are rooted, but stock.

Even though in most benchmarks my rooted Atrix, with a custom 1.45 GHz Kernel and optimized ROM (The Darkside) is almost equal or a bit superior to my SII, it feels slooow when I use them side by side. The Atrix takes some time loading the app screen, the touchscreen lags, and 3D games are definitely slower, no matter what benchmarks say.

Here's the strange thing. My bone-stock Nook, at 1 GHz, scores exactly the same in the Nenamarks 2 benchmark (24.8 fps). Both machines run games at pretty much the same speeds, even though the Nook has to move quite a bit more pixels, and that the Atrix is running 45% faster. Considering the Nook is a bare-bones tablet, one of the cheapest out there, it's a surprise that it can run as fast as an OC'd Atrix.

Does this mean our once powerful device is now almost obsolete? :(
[Atrix 4G General] mvgc3:
My opinion my not count for much, since I haven't used any other devices, but my Atrix meets and exceeds my expectations for a phone.

I generally don't play 3D games, simply because I despise touchscreen controls. On the rare occasion that I do, they run fine, though once again, I can't compare to any other devices.

The app drawer loads quickly (I keep it pretty organized with folders, which might help), and I don't have issues with the touchscreen lagging. That's all staying on stock speed too. I have an OC kernel, just in case, but I don't use it much anymore.
[Atrix 4G General] WiKiDCLown:
I have friends with the new nexus and the galaxy s2 and my ATRIX is considerably faster then theirs even when I was running stock rom now that I'm running new ics with a 1.3 OC it spanks their cells
[Atrix 4G General] TravisAntonio:
Try CM7 and then come here again.
[Atrix 4G General] Magnetox:
QFT///////
[Atrix 4G General] Neroga:
Try out Joker's or Turl's CM9 builds. They are considerably faster in terms of touch responsiveness and opening apps / app drawer. From my experience, blur is just plain slow.
[Atrix 4G General] fjhuerta:
I won't since I need the webtop.

Still - and I can say it without hesitation - the Galaxy SII flies next to the Atrix. It's my wife's phone and it used to be mine .- so I know what I'm talking about :)
[Atrix 4G General] fjhuerta:
I'll do just to see if Blur is really that bad... but I use the Webtop everyday at the office :(
[Atrix 4G General] dotvezz:
I can confirm that with cm7, and especially with cm9 kang builds, the Atrix absolutely flies. It really is clearly better once you get rid of Blur. Fortunately for you, there are plenty of ways to get a deblurred ROM and add Webtop to it. There are also customization options that improve Webtop performance.
[Atrix 4G General] TwilightZone:
I've never had a speed issue quite the opposite. I pretty much hacked it instantly but I've always enjoyed great performance. Some custom roms are better then other and the stuff without blur definitely show speed gains. I did find wet dream faster then darkside and in the end moved to CM roms instead. Neutino was insanely fast I was outdoing my buddy's SII on benchmarks. Something you might want to consider is dropping your OC kernel down a bit. My atrix doesn't do the 1.5 kernels and the closer my overclock gets to it the slower and more unstable I get.
[Atrix 4G General] WiKiDCLown:
Neutrino rom is the fastest and it is very stable if you flash it then flash the latest fruit cake (webtop only) you will have an incredibly fast ATRIX with your webtop it is all fast and easy to install I personally had a aututu benchmark of 9000+ every time and a high of 9267 and I was using the v6 script and elite 1.6OC

Hit thanks if you found this useful
[Atrix 4G General] guidoido004:
The problem is the lack of the I/O performance caused by the MotoBlur bloat.

I use CM9 and VNC to boot ubuntu when want to used webtop, and man, honestly, its beautiful.

You should definitly give it a shot! No, you have to, and see with your eyes, how much good the atrix can be.
[Atrix 4G General] sk8trix:
I do notice the difference a lot. I was using cm7 weeklies and the device was super responsive,benchmarks were high but honestly its all pointless it really comes down to how fast it handles real usage not numbers a benchmark gives you.

On blur roms the phone is always laggy but since I need webtop as well I gotta use it this way.

I also own a droid i credible with a snapdragon processor O.C to a little over 1Ghz and its single core and on cm7.1.0 and its almost as fast as my atrix.......kinda makes me mad but the atrix wins as far as ram,memory,and handling games....
[Atrix 4G General] JuanDaDon86:
Now imagine Atrix 3
[Atrix 4G General] djluis48:
I would like to know how sir. :)

Its possible to have Webtop on CM7/9? O.o
[Atrix 4G General] JoeM01:
i don't understand the point of benchmarks, other than bragging rights.

now, I've used them because I guess that warm feeling of some kind of metric saying the phone is "faster" is nice. Still, usability should be the most important thing.

for me, on a daily basis, my atrix performs how I want it to. It's not overclocked, but it is running the latest alpha of cm9, and on the newer version of quadrant it's scoring around 3400. But really what does that score really mean? Not much if you ask me.

i don't see anything on the market right now that makes me want to extend my contract term. phone does what I need it to, and well.
[Atrix 4G General] TravisAntonio:
1 month later but, yes.
[Atrix 4G General] elvisrps:
if you want good performance and webtop: Nottachtrix ... Rom very good!
[Atrix 4G General] xey3x:
I completely agree if you compare the stock Atrix to most other stock Android phones of comparable stats the Atrix is slower. But with custom Roms (I can only really speak to CM7 and Joker's CM9) I actually find that my Atrix performs better than other phones with custom Roms. It seems Blur/Motorola stock is just programmed poorly but the hardware is solid. I am not overclocked and I use Joker's CM9 as my daily driver it is so smooth it hurts my brain!:D
[Atrix 4G General] xploited:
Also, it seems like the Tegra 2 chipset is slower comparing to the newer dual core chipsets (like the TI OMAP 4430 on the Atrix 2).

A stock Atrix 2 with motoblur is noticeably faster than Atrix 1 with CM7, sorry. :confused: I have both phones right now and can compare them side by side.

I still think that Atrix 1 is the best Motorola phone currently, mainly because of the unlocked bootloader and great custome ROM support (Nottachtrix, CM7, MIUI, Neutrino, 4 ICS roms :D).

I will be keeping my Atrix 4g for a while, until Razr drops in price and (if) it gets good developer support.
[Nexus S General] RushAOZ:
So.. I'm sure some of you have seen me *****ing about my battery life. Well 2 days ago I moved back into my mothers. Where she lives, sprint is pretty weak. So for 3 days I've had basically 0 web access. No 4g at all and 1 bar of 3g. I thought this was normal. I had a job interview today at home depot and couldn't make a phone call for about 2 hours. Or send a message or even get 3g service. So I decided tto flash back to gingerbread tonsee of that helped. It did. I was able to make phone calls and messages and even have 3g service inside the home depot. Which I couldn't do with ICS installed. So unjust thought it was a tower being worked with. I just got home. And to my surprise I have a stable 3g connection. No longer do I have to walk out the door just to have 1 bar of 3g. Im sitting in my living room right now and I'm on Facebook, doing some web browsing and obviously posting on xda which was IMPOSSIBLE last night.

Google, there is something really wrong with ICS. Please.. for the love of god figure out why ICS has bad signal really reception compared to GB.
[Nexus S General] Deleted member 2574792:
not sure what the exact background to all of this is, but did your radio change between the two ROMs?
[Nexus S General] RushAOZ:
Yes I did. I tried all 4. Switched kernels left and right. Flashed roms left and right and always got the same result. If I hop back on gbread my battery goes 16+ hours with great reception. ICS gives me horrendous battery life.

Ill report back gents.
[Nexus S General] eksasol:
I pretty much agree with you, I had serious battery problem with my i9020t with ICS, battery would not last 6hours. Flashed GB and its all good and so much faster.

But either Google or Samsung isn't really prioritizing on these phones, which is sad given its not yet more than 2 years old. I hope this is not the case and they spend time sorting out ICS. So far ICS haven't amaze me in anyways though, I just want a light and fast OS with good battery, GB is doing that right now, not an overly expensive quadcore phone with poorer battery life and only marginally faster.

Haha I'm sorry man lol I didn't mean to say you, but I'm sure at some point some dolt will come in here and call me an idiot and tell me I'm doing something wrong. Sorry it seemed I was implying that. Anyhoo this might be the reason its taking so long for us to get our ota. I don't think half of you will notice it because of your sitting in a position with a good signal your phones wont struggle as much. But to me it "feels" like theres a -10 dbm deficit in signal strenth. Right now I'm at -96dbm and I have 3g access in my living room. Flash ics and the only way ill get an ounce of data is if I step outside. And even then I only get a measly 1x.
