Curious lag into CWM - Galaxy S III Q&A, Help & Troubleshooting

Hello, so yesterday I was updating my phone on the primary and secondary rom. As usual using the recovery from Siyah.
The first problem I notice was the wipe data process took more time than normal, then the rom installation itself took a LOT of time, more than 5 minutes.
After the rom installation I tried to flash the JB Domination and the process took like 8 minutes or more.
This also happened using CWM Touch which was working well until yesterday.
Then booting into the rom I notice the performance was a bit laggy, when calling the keyboard or any other normal action takes more time than normal.
Do you think this is a symptom of a damaged memory or partition?
Any suggestion or its better to send to warranty? since the phone its a bit laggy now, and it was not a few days ago.
Regards

Try booting only a single rom and remove all traces of the dual boot. This has always caused issues and has never been completely stable for long periods.

I don't know about partitions and stuffs but I think you should start back from square 1. Flash back a stock ROM through Odin (the latest firmware) just install cf root and see if the cwm bug is fixed. Maybe it lags cause you've been flashing a lot lately?

the curious part is the present lag into CWM.
i will do a fress installation and test.

Hmm ...

It might be a symptom of some small bad memory blocks starting to develop - but I doubt warranty will cover that.
It is also possible that the speed is related to the amount of free erase-level blocks (something like 256k to 1MB in size I believe) internally available to the flash controller - just as in most SSD's the write performance plummets once you get over 50% of the flash marked as used!

You will find no phone that can handle dual booting without lag. Your lag came from that.

Because the system wasn't designed to do it. Android is still a baby in the OS world and has not even been optimised for anything more then a dual core let alone dual booting on a very limited system. Even multi level threading is not up to par yet.

the second rom was there long time ago, the lag was new, just two days ago.
The lag was present INTO CWM recovery, no just a normal lag rom. I think this is related to bootloader or bad blocks/memory failure.
Anyway seems ok at the moment (Still on siyah kernel)

How often do you swap between the two? I have never seen any lag when in recovery as there shouldn't be any as long as the recovery isn't getting messed up.

Phone turns off itself

Hi. My phone often turns off since I flashed official Gingerbread (2.3.3) ROM.
When it turns off, I'm usually using it. Till now it never turned off at stand-by mode. Does anyone know, what causes this?
Other things:
1. When I played FIFA 10, the football field's textures weren't showing, but everything with field's players was fine.
2. When I ran Quadrant Advanced, at "3D Corridor" and "Planets" there were no textures. When I run the Standard version of this app, there are no problems.
Maybe gpu is cooked?
For starters, tune down your overclocking.
Ok, I'll try it and then I'll say, did it work or not.
You are probably going to seriously eff up your phone at that high overclock. It might even burn/damage the inside circuits if you're not in a really cold country.

I just clocked CPU to 245/710 MHz, I had 787 MHz max. But anyway, before I flashed official 2.3.3 ROM, there wasn't a problem like that.
EDIT: I installed NFS Shift game to see, how are the 3D graphics working. When I tried to enter this game, I couldn't get further than EA Games logo - the game powered down and I had brought to the homescreen.
I can't fix this issue by installing another ROM, right? ... It's related with hardware.

Yeah,LG replaces your PCB circuit in 1/2 days AFAIK so I would like to risk too and flash new baseband but I'm going away in about 4 days (@ the beach ) can't risk
Thank you, guys. I'll go to the shop where I bought this phone and will ask about warranty.
Thanks again.
UP!
So, I didn't repair my phone with warranty, I only flashed stock Froyo with KDZ updater and everything was solved.. but.. I still have this problem with ROMs that are based on official Gingerbread (also with official GB, that's not modified) and with CM7 by mik (only with build 6.6.1)..
Can someone try to play NFS Shift on official GB (or a ROM, based on it) and answer here - is it working or not.
(for me it crashes after EA logo)
well, I count it as a .35 kernel issue..
What do you think?
I've tried it a while back (when it was €0.99) on stock firmware and couldn't get any further either. Got a refund, so I can't retest it on the CM7/mik I'm running now, but it could very well be a general issue.

I see...
So, currently for me the best choice is mik's CM7 build6.5.7 (uses .32 kernels) + fk v18.
I leave that entirely up to you... I just want to protect you from trying different ROMs in search of one that is able to run NFS, when it may very well impossible

yeah, so ROMs that are based on froyo (or .32 kernel) are the most stable.
never got NFS Shift to work on 2.3.3 ROMs.
(actually I don't play this game, but with it I can see, how is the ROM working)
that's my conclusion.
btw, haven't your phone have the problem with automatic turning off in GB?
thank you for responsiveness.
Sorry, the only screen-turning-off phenomenon I see on CM7 is the one I see when I use Skype... hate that darn proximity sensor
As for stability... well, it could just mean that NFS works on a bug-assumption that has been fixed in the meantime. Wouldn't be the first time.

sry, but i didn't mean screen turning off - phone is turning off.. it just immediately turns off, but this happens only when I use it.
Ah! ... sorry, no idea aside from the usual: Do you overclock? Do you have a lot of applications on SD? Do you use a task killer that may be over-eager? Have you checked your memory stats?

too much oveclocking indeed..
yeah, the phone was overclocked always. at beginning @787 mhz, then 729,and after that 768
on sd I move applications only then if they are bigger than 10 Mb (sometimes I don't if there is enough free space in phone's memory).
don't use task killer anymore. I used it earlier, but understood that there's no point of this.
I don't check my memory stats, but do I have to?
You shouldn't have to ... but if the phone crashes then at least something isn't working like it's supposed to, meaning anything is possible. You can get your memory stats with cat /proc/meminfo .
Have you tried running the fix permissions function in ClockworkRecovery? It never worked with any of the issues I had, but it's worth a shot.

[Q] My Atrix 4G is suddenly slooow (problem with database i/o,sd?)

Hi all! I'm an italian guy
I bought my Atrix a month ago in a bundle with the lapdock and the hd dock
Yesterday it suddenly gots this problem and now it seems to running very slow without an apparent reason
Some applications and games are running normally but download from the Play store is almost impossible and I have to wait some seconds when I unlock the screen or when I open some apps
Also the boot is slower then before
I've done a complete wipe but nothing changed
Then I tried to run Antutu test and I was surprised... ram, cpu and graphic scores are normal but the Database IO results is only 5!! Also the writing/reading speed is very slow
What can I do? Could it be an hardware issue? I don't want to return the phone again (I returned the first one because of the "bad update" brick...
Many thanks!!!

Maybe a bad sdcard or you may need to run a ram fix since you are international. Ram fix search from a PC should find it for you.
Sent from my MB860 using xda premium
thank you but i don't think the problem is the ram or the sd card
the "system info" apps show the normal amount of ram and the performance seem normal from the antutu test...
and the problem is the same with or without an sd card in the phone
no one has an idea?
when i opened the post my phone was stock locked but rooted on 2.3.4
now i unlocked the bootloader and i'm running the topogigi 1.1 rom but the situation is still the same...
is there any app for the phone or the pc to test the atrix and find hardware issues?
thanks again!
had similar issue. ran the zip. runs like a charm.

pdsfix.zip
my antutu scores are back up to around 7000. less lag in app drawer and opening /closing certain app. its back to silky smooth yeehaw.
i ran pds fix but nothing changed... still very slow on boot, still "lag" when i unlock the phone, still impossible to download anything from the market/play store and slow when opening apps etc... do i have to start study how to return the phone locked and stock and return it?

Having a similar issue. 2.3.4 and my write speeds are .5MB/s and my read speeds are like 21MB/s. My free space is 4GB+ and i have no external SD. This just happened a few months ago, I thought it was normal until I tested my write speed and found it to be atrocious. I've tried changing schedulers with no change. Market updates take FOREVER and freeze my ENTIRE phone for about 20seconds to 1minute depending on the size of the update. My normal apps freeze when opening and/or saving. Any ideas??
Motorola Atrix MB860 2.3.4
Update: Tried PDSFIX, no change.
I've done a bunch of research and a lot of other users with newer phones are having this issue too:
http://code.google.com/p/android/issues/detail?id=37258
I still haven't found a solution. I can't use mount -o remount,discard as discard is not an option with mount on Android 2.3.4, apparently. Any ideas? Or should I just throw my phone out the window? :crying:
Some people say it's due to no TRIM being activated. I found a fstrim for linux but it's a .c source and I'm unsure how to compile without downloading an app from the market for $3! I'm not sure why randomly it decided to kill my write speed. I've even tried an app to fill up free space and delete it, but nothing is working.

I understand that it's for a newer version of android. All my searching has lead me nowhere with my problem of insanely low write speed :|
SEQ RD: 16.65MB/s
SEQ WR: 0.36MB/s
RND RD: 1123 IOPS
RND WR: 33 IOPS
Buffer: No
Kind of saddening. I should maybe just buy a new phone... Motorola seems to have given up on it, as seems to be the norm after a year. I don't really like everything being designed to break in a few years but whatever, good revenue stream for them :silly:

[Q] insufficient ram/games lag on galaxy s3

hey guys. im pretty new to this android thing im an ex iphone user.
i use this task-killer app to show me how much RAM i got left and it always
show something between 250-100 mb of ram left out of 1024.
when i try the Antutu Benchmark i only get a 6000 score when
i saw ppl get 11000+.
the GPU score is fine and the I\O is fine the RAM is way low then others and the CPU score is low too.
what may be causing this problem?
oh btw when i play games like NOVA 3 and Gangstar Rio it laggs as hell.
Ty.
No games should lag the S3.
Firstly what firmware are you on?

im on 4.0.4.
yea it seems wierd to see souch a powerfull device lags.
i guess it has something to do with this low benchmark score i get..
Ok I was after the exact firmware revision and if you were using a custom Rom or not. Once that is established may be able to help a little more.
Sent from my GT-I9300 using xda premium
You need to provide more info before any of us can help out. Provide which ROM & kernel you are using & if it's stock. do you freeze or uninstall bloatware? what apps do you have running or are there any running while the games are running?
Your total RAM is around 700ish since the OS uses the rest after that, so having 250 or lower is normal. I have yet to experience lag when running games like the ones you've listed & the only time I ever have experienced lag is when the home screen redraws.

what do u mean by firmware revision other than 4.0.4?
Did you flash any custom kernels? Only stock kernel seems to run right with heavy 3D games (ie, NOVA3), custom kernels always lag, then crash and reboot on me.

This might be stupid, but where did you get your SGS3 at?
Honestly, Flash a stock ROM with Odin. I don't know if there are any one click master clear ones, but if you have the international there should have been any hacking needed to get it to work in your country.
Goto settings / about
Latest UK firmware ends lf2
Also check settings power savings and check cpu throttleing isn't on. Even with it on 6000 is real low. I hit 9000 with cup throttle on and my phone hasn't been rebooted in over a week.

i havn't flashed anything and i got it from a licensed Samsung seller in Israel.
the problem is i know they do some modification to get it to work right
with their langauge.
and they install their own rom.
i only download games and apps never to touch rom/root.
it's the international version with quad core.
when i compare the result's i get on the Antutu Benchmark it show
i have half the score on the ram and processors then i saw on Youtube.

Never heard of an international phone not working in Israel without a modification. Personally I'd connect it up to kies and see if there's an update available.

Just thought I'd add that kies is the official Samsung application for updating your phone and won't break warranty etc.

lol mayble ill sound naive but won't i lose my warranty?
i remember when i first took the benchmark test when the phone was
just out of the box it showed me 11500.
now 2 weeks after it gone in half.
is there a way to root without lossing warranty cuz i know their rom is not
out on the market yet.
the phone will work in israel without the modification but it will have some bugs with the langauge

Yes and no. Odin uses the same update mechanism ('Download mode') as the official Samsung Kies (which btw is a grotesk, slow and painful-to-use application) so the phone won't be able to tell _WHAT_ updated it.
The phone is only capable of telling whether the ROM (=firmware) you're flashing is Samsung-official or some aftermarked custom ROM.
When it detects the ROM not to be official it will display a corresponding notice (and counter) in the Download mode. However there exists an app (which requires a rooted phone... which you usually got on custom roms) called 'Triangle Away' capable of resetting that counter to 0.
Now of course the store could still boot up the device and check if you're on the original ROM, so you'll have to flash a Samsung-official ROM corresponding to your location before bringing it back. There is no need to reset the counter afterwards since, as said, official ROM's don't trigger it to increment.
What if your phone is so damaged that you can't get it to go to download mode (more or less hardware-bricked)? Well in that case the store won't be able to check if the phone is (was) running non-official firmware. Samsung could but they don't always do since it requires dismantling the device and dumping the storage chip (provinding it still works). In case software caused it to brick (not boot) and it's unrecoverable, there are stores and send-in services around that for a couple of bucks revive your phone through JTAG flashing.

The reason for your scores dropping might have several causes.
Please install 'Task Manager' by 'Houmiak', reboot your phone and open the Task Manager. Then kill all processes of programs you've installed which might have autostarted. (Note that some auto-restart as soon as they're killed, so you can't really get rid of them). If there are a lot of such apps,
try installing 'Autorun Manager' by 'Andrs Studio'.
Then run the benchmark again; is it significantly higher? If so, the reason most probably is that your app(s) are causing the issue.

ty for the helpful reply.
i already use Task manager. ill try the other thing u said.
the wierd thing the benchmark isnt stable it can show me 6000 and on the next one it shows 8000.
UPDATE: it made it to 12000 once and i tried it again and it went below 10000
Another update:
It seems that the low score appears when the phone i hot like after
Playing a heavy game or after taking the antutu few times in a row.
Its getting lower and lower each test.
If someone please can try taking the test 4-5 time in a row
And publish the scores here ill be gratefull.
Then ill know for sure if my device is factory defected.
make sure you dont run the benchmark with the power saving mod on

[Q] Im bored...

Hello guys.. I'm a flashaholic.
The reason i'm here, is because i've just realized, that i haven't had my quick fix for some time now..
Everything seems so stable, except the *mic* issue, but hey, i fixed it with a hands-free.. Otherwise, i'm very happy with my phone, it works, it doesn't use up that much battery, and it doesn't crash, you can even do normal stuff to it.
But to the point.. I really, REALLY miss AOSP, especially the theming.
I can live with the occasional bugs, though i wish it could be at least somewhat stable.. *You know, im not that picky*.
But the one thing that keeps me from using AOSP; is the camera app from Sony, because i like taking pictures of my son, and the environment..
Are there any Camera app out there comparable to the Sony equivalent?
Oh, the urge..

I have the same urge, I wanna get the full output from my Xperia Z2, feel all those four cores working in my hand. But that one Sony Camera app stops me because it's beautiful. It's matchless. That's the only reason I'm not changing my ROM and be bound to what Sony's put in my phone.
I am in the same boat here! I want to flash PA so bad especially with all their features but then the camera app, the noise cancelling features and x-reality etc is really stopping me from doing so
i use to be in the same boat before i noticed there is no point to flashing roms when im on a rom which does what i want
perhaps you should find a rom which has what you want
Same here.I literally used to flash a new ROM on my Nexus 5 everyday. As has been said though, the stock Z2 ROM does everything I want it to and rooted with some xposed mods its perfect.I just have to learn to live with my phone the way most other people do.
just a note
formatting then writing a rom to your system slows your device ALOT, it also cause alot of other issues but that comes after long wear n tear

But I've done clean install via Sony PC Companion for 3 times now... So does this mean my phone isn't as fast as the day I bought it? Even though I've installed a clean ROM?

I remember reading somewhere years ago that flashing new firmware over and over will eventually wear out the hardware and cause it to slow down/eventually fail. I can't seem to find anything for this when searching though! Would it be possible for you to shed some light on what I should be searching for or what causes this issue?
Thanks in advance!

there is something called read/write cycle life
you can only write info so many times onto a disk before it wears out and stops working
formatting a partition takes a huge amount of cycles, installing roms does the same too because its alot of data that has to write
some info

Cheers for the reply! From what I read on the link, it says most flash memory have a P/E cycle of around 100,000 and from what I can remember, it varies depending on the type/quality of the flash memory used (Nexus 7 2012 had rubbish flash memory which a lot of people complained about). Just going off an assumption that the Z2 has a P/E cycle of 100,000, wouldn't it take quite a lot of ROM flashes before the memory deteriorates? Or is it more due to the size of the data being written/erased than the amount of times it is being done?
Sorry for the questions, I know this isn't the thread for it but it is interesting to me!

I used to flash a lot roms everyday on various devices. I didn't notice any side effects of it. As I know a little about hardware there is nothing to fear. You can imagine than one memory cell is one bit of data. If it withstands 100 000 writes it literally means that you can save data (eg. flash rom on it) 100 000 times. There is no way that you can cross this number even with everyday flashing. And it doesn't matter how much data we are writing because each memory cell deteriorates individually, so if we write on 1000 cells it means that every cell will deteriorate only by one write operation which means every cell will still be able to be written 99 999 times.
Another thing is that the storage memory in smartphones is usually one chip which means that all your data including /system partition (which you overwrite during rom flashing) and your photos and music on /data are on one physical device. The conclusion is that if you are afraid of rom flashing and wiping you should also be afraid of saving photos to internal memory. And since we are using our int. memory and change files placed on it a lot it means that we can flash roms as we please without consequences.

Thanks for the thorough explanation. I had my suspicions this would be the case and you've driven it home by explaining the whole music/data/pictures scenario. I used to flash PA and other roms on my N4 more often than I care to count but I never once saw a decrease in performance so it's good to know (personally and for others) the phone's read/write performance is not going to be realistically affected! :highfive:

I've flashed previous android devices ( HTC magic / Desire HD / SGS 3) 100+ times each with no obvious slow down, my albeit limited understanding was that NAND chips where rated for 100k+ P/E cycles?

Correct from the wiki link provided a few posts ago:
"Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[21] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008"

severe lag issue

I've had this watch for about a year now, and have recently noticed some sever lag. I've tried factory formatting it and running with nothing installed and it still lags. It's to the point where its unusable it stutters even when just swiping away notifications.
tbh it always lagged, it never goes super smooth but that's Googles fault for only allowing to enable one of the 4 available cores on the CPU.
Have you maybe had flashed a custom kernel at one point which got removed with an update? Of course a factory reset won't help either then, only "possible" explanation I could think of now.
