internal ram full, phones freezes then reboots

ok so this will happen quite often to me after messing with customizations or just using different apps. I exit apps that stay running correctly (at least ones I know I need to). my ram will fill up, or almost up and then the phone will freeze for a few seconds. when it comes back up I open system panel and close all inactive apps and anything else I feel needs to be closed. this will leave me with 50% or less free.
usually i'm not concerned, but twice now my phone has rebooted due to this. this happened once back in june and now just today. I had navigation up and when I knew where I was going I woke up the phone to exit it, but the phone was frozen. so I put it down and it actually keeps giving me directions. then I heard the start up tone, I didn't bother to look just put the phone in my pocket. a few minutes later it reboots again. again I didn't bother cause I did not need it. when I did need it I found it with no cell or 3g reception and no icons loaded up. reboot the phone manually and all is fine.
I am rooted with the latest fresh rom. but I have only been rooted for 6 days and I have been getting this memory issue the whole time I have owned the phone(release day purchase). including one reboot before rooting.
I keep reading that we should not have to worry about memory and that android takes care of it by closing apps when new apps need the memory. is this really true?
usually I keep it free by using system panel but I forget sometimes. I haven't used task killers as I read mix reviews and I like some things manual anyways.
so, is this normal? am I doing something wrong, or is there a setting I need? do I just need to go get a task killer?
what are the best task killers? and is there any programs I should not kill? or whats the optimal way to set these up?
thanx for any help you can give me

Try using Advanced Task Killer (there's a free version in the Market) and change its security settings to low, then start killing processes you don't need.
While Android is supposed to have good RAM management... Well, as you can see, it's not that great. Generally, if I get under 100MB of RAM available, I tend to go on a killing spree... Of processes.

Task managers on Vibrant - what do YOU think and why?

So I am reading the tips and tricks article - GREAT article by the way! - and I come upon the note stating to not use task killer (shown below in bold).
SHOULD I USE A TASK KILLER?
Absolutely not. You have the best OS and one of the best spec'd phones ever. You would be doing more harm than good. If you do have one, uninstall, reboot and let me know what you think!
In addition, even Google at Google I/O 2010 addressed app developers and asked them to no longer include "quit" or "close" as options within their apps. I think Andronica (another great android site) summed it up well with their article, found here.
XDA user iunlock created a thread with some good debate based off this sticky. You can read all the thoughts by clicking here. In short, the overwhelming majority agreed and some have commented on seeing an increase in performance after deleting their task killers. Awesome job guys.
That having been said, I went a day. Sure, it ran smooth, but my battery life stunk.
I'd like to hear from other users on the pros/cons of using a task manager on your Vibrant. Not trying to start a flame war, just wanting to hear thoughts other than my own (and the little voices that come from the ear piece of the phone )
Personally I am completely for it, as long as you are not killing off critical processes or apps that you use on a regular basis. Bottom line here - know what you're doing.
Feedback please?

I had the exact opposite reaction after getting rid of the task manager, battery life increased.

I kept ATK, battery life improved with it. If i play games and then hit the Home button which i always do. it stays running in background and kills the battery. Didnt really notice much of an impact with performance but my battery life increased

I use task manager. people can say what they want, but lowmemorykiller is designed to kill apps when the system needs memory. our phones have a lot of memory so they are capable of keeping so many apps open, if no one believes me download a task killer and just open it up to see how many apps are really running on your phone, its ridiculous, especially if you still have the bloatware. I don't necessarily use it because my phone bogs down from so many apps (that reason was back in the day with my g1) i do it because theoretically your battery life should go up. What's worse, a task killer running, or the last 20 apps you've used? All I know is my phone runs fine, smooth, and has battery life that I really cant complain about. It's hard to really tell what is correct though, I mean theres's hundreds of posts about the gps on our phone and mine launches up, finds my exact location within 30 seconds, and navigates perfectly. Got mine the day it came out, so ive really never worried about what other people have said, i just find out for myself. try both and see what you observe to be best.

I own(ed) a G1, Google Ion, myTouch, CLIQ, Behold II, Nexus One, myTouch Slide, GARMINfone, and Samsung Vibrant.
I have never used a task killer / manager on any of them and have never experienced lag on any of them.
My battery has also lasted from wake (9am) to bed (im usually in the bed by 11pm, sleep comes much later) on all of them and that includes at least 2 hours of stereo Bluetooth music. WiFi, GPS and Sync on all day. Bluetooth and brightness are managed as needed.
I'm no developer, but I have flashed my fair share of roms, and run plenty of tests. I don't know what is best, but I do know that they are NOT NECESSARY. Are they helpful or useful to you? Possibly. If you want to use one, have fun. I see no reason for me to start now...
EDIT: I also play a fair bit of SNESoid, GENSoid, and now PSX4droid....
Also, I don't have a car charger or office charger. I only charge overnight.
If you have to use a charger during the day, you blew it.

Task Mangers slow my phone down more. I don't use them.

Android has a task killer built in to kill apps if memory is low automatically.

Couldnt enjoy my phone without one.

I know, read. I referenced that in the first line. It's a low memory killer, my phone still has 100mb of memory available even with 15-20 apps open. I'd rather have those tasks not running if i've finished with them. Plus apps also reopen periodically by themselves, auto-kill on a 3rd party task killer will kill this as soon as the phone is sleeping, the build in task killer will not.

There's no way your g1 ever lasted 14 hours, let alone consistently with that usage. Either that or you dont understand how some of us use our phones. The only reason this must be such a debated topic is because there truly isn't much of a difference. Will your phone have a weeks worth of battery life with one? No. Without one? No. Users preference I suppose, but before i deleted bloatware, my telenav and slacker radio were always open and i honestly never even opened them to even check them out.

That having been said, I went a day. Sure, it ran smooth, but my battery life stunk.

People will give all sorts of anecdotal evidence one way or another about this topic. Just keep in mind that anecdotal evidence won't answer the question. It's not a simple yes/no question either.
Here's the deal. *IF* you have errant tasks that are causing partial wake issues (running too much or too often when the phone is supposedly asleep), those applications will be the culprit for your bad battery life.
These are not likely to be core tasks of the OS, or OS bundled bloatware either...but they can be. When I had my Behold II and was running ADW.Launcher, for instance, I had to use a task manager to keep parts of Touchwiz from waking up and complaining about the UI not being front-and-center. And the reason WHY I used a task manager was a simple one. It was a core data task of the embedded software that could not be REMOVED.
The best solution to partial wake issues is to identify the tasks that are causing them, and GET RID OF THAT APP. In my very specific case above I was unable to do so, so a task killer had value.
The reason why task managers can be a very bad idea are legion. The Android OS runs a lot of interdependant tasks, and killing one seemingly innocuous task can and often will start a domino effect with other tasks that rely on them. It can even cause other dependant apps to eat 100% of cpu time during sleep cycles or at other times, and make your battery life mysteriously go to hell.
So far on this Vibrant, I've found no core tasks causing partial wake issues. Third party apps and widgets however, I've found quite a few that "wake up" and cause partial wake issues (i.e. they are spending too much time working and running when the phone is in "sleep" mode). Pure Messenger Widget being one of the nastiest I've tried lately.
What do I recommend? Use the built in battery statistics, and install the market app "Spare Parts". This combination will give you the ability to glean useful information about exactly what is running and what it's doing. There are other tools and whitelist managers that you could employ as well, but this is enough for me.
And even if you are running task managers and killers, you should be using the above to know whether what you are doing is a complete waste of time or even making matters worse.
When left to its own devices, Android 2.1 does a remarkably good job managing tasks and memory, PROVIDING THAT 3RD PARTY APPS ARE BEHAVING. Since we all run a very different set of 3rd party applications and widgets, it's no wonder that people are having battery life issues (great, bad, not so bad, etc..) all over the map.

I use Advanced Task Manager Pro and I love it. The close-all widget is great because it closes everything except what you have told it not to kill, and it kills itself to that is not running down your battery either.

I don't know what to tell you other than it did.
I am a pretty heavy user, but I do have fantastic coverage and work in a bright environment so brightness stays down. SetCPU works wonders.

I tested my Vibrant today. Came off the charger at 5:30am. It's now 10pm & my phone is freaking out for juice. I think my G1 could match this.
I'm constantly pulling from Gmail & Exchange (usually on Edge - poor reception in the office). I used GPS for about 10 min on the way home. Once home I started wifi. I turned it off an hour ago to play a few rounds of Let's Golf.
That's not terrible for such a badass smart phone, I think.

I personally will only have a task manager installed for when I'm working on my game / app projects, as to make sure they properly close when exited or to kill them if something goes wrong (neverending looping media), so I don't have to reboot the phone.

I was using atk before my last factory reset. I've decided against it now though. I've also decided not to use any more web apps when I have a perfectly good browser. Just seems like a waste of resources to me and my phone is much quicker without them. That and launcher pro have made this feel like a different phone. I think the combination makes atk unnecessary.
If I decide to keep this phone I'll reroot and clean out all the crapware. I'd prefer to keep this phone well-maintained like my computer sip that a task killer would be mostly unnecessary.

GT-i9000m has been locking up recently to the point of removing the battery.

It went from extremely rarely doing it to three or four times just the other night in the span of a few hours. I can't reproduce it on command but it happens when I lock the screen and put it in my pocket. Then sometimes when I take it out it is entirely non-responsive, even the power button doesn't work. I have to remove and reinsert the battery.
It could be ADW Launcher or WidgetLocker since those are the only two programs always running, but I was hoping someone else experiences a similar issue. It hasn't happened when I normally lock it yet though, so it could also be the proximity sensor maybe?

Having the same issue (on Bell as well), but not running either of those two apps. Was almost to the point of returning the phone and then installed JM7 and it's been better, although not perfect. Last night it locked up with NoLED displaying an icon, so I've deleted that app to see if that's the issue. It hasn't locked up today, but it did reboot a few hours ago seemingly at random. :shrug:

Your internal sd card might be failing like all the other i9000m phones I see on this forum bricking themselves .

Oh, that doesn't sound pleasant at all...
I'm outside of Bell's 30 day exchange period plus I've talked for over 30 minutes, so I'll have to go through Samsung if it completely breaks. On the plus side, a phone from them should be three button recoverable.
Although I can't be without a phone for weeks, I hope it's not the SD card.

Mine Lags like crazy once every few days till the point I need to restart it. Any idea why this is do?

Hold your horses people....
before you jump about the lag, and or one click lag fix and such
first you have to investigate what is running on your phone.
just over the weekend (since XDA was down) i stalled over 400 Apps
my phone slowed down to snail speed, then i ran my Startup Manager software (many to choose from)
I suggest Startup Cleaner 2.0 then uncheck everything, leave only the apps that you want to run during start up
reboot your phone and presto, fast as new!
if you can find version 2.1 of startup manager that one is even better
keep note, start up manager apps are not the same as task killer apps
it only run once during start up, and it helps you easily select what should and should not run during start up, so it doesn't stay in memory after it runs
on the same topic
you should also configure your Task Killer apps to kill everything, and add only the wants you want to be running to the ignore list.
that will keep the phone working smoothly even without the "one click lag fix"
i'm still running stock on my JH2 i9000m

All gamer has a good sugestion here BUT we are going to get people flaming the fact that Android shouldnt need task managers.....
Ho hum..
TBH in my experience, I have found (after a couple of hard resets) that there appears to be a size limit for installed apps. Once I get over this size limit, I get LAGTASTIC, phone slows to a snails pace, then I remove a few of the apps and I am back at light speed again....
I cant say what the limit is, but I know when I have hit it - I would then uninstall a lame app or two and get back running.

Yes a lot of people "claims" that, but yet you do a search in Android Market, you see LOTS of Task Manager / Killer apps for every phone.
they were not designed for Galaxy S, they were designed long ago for all the other phones that had and still have the same problems of memory management causing lags
Android is not robust enough to survive without one
heck not even Windows 7 or Windows Mobiles phone

I just read that possibly the phone freezes while trying to find a signal. As this problem has only recently started, and I just recently moved into university, and many buildings receive little to no wireless signal, I think it's more than a coincidence. I'll try going to plane mode before entering lecture halls and basements.

[Q] lags, high cpu and assorted sluggishness

I am using CMYLXGO's NAND stock Desire HD build. Its great. However, I am having so many lag issues. I seem to be one of the few that is experiencing this with the build so i turn to some of you to see if you have had similar issues with your phones.
Problems:
1. when auto populating apps (like using installer, uninstaller, managing applications in the system tab) the phone will take forever to pull up all the apps , the screen will cut off (because the screen times out) and when I hit the home button or any button to cut the phone back on it stays black.
2. every action makes the cpu run high. adding a widget to the home screen (apps populating issue again), changing screens really fast and other assorted minor processed.
I have stopped auto sync
I do not use auto rotate any more
I do not have any rogue processes for the most part
I don't understand why I seem to have these lag issues. Everyone else talks about how fast and fluid the build is. I am under the impression that with the build NOT being run from the memory card NAND would add to speed. This is not happening for me. If anyone has any idea why this is happening. I am convinced it is something on my end but I don't know where to start. I am open to suggestions.
I have 2.15 radio, 16 gig class 2 memory card.

Hmmm, not sure but have you tried another ROM similar to see if it does the same? You can also go into MAGLDR and wipe dalvik cache. I used this ROM and all was good for me. I have sense been using this one which is also working very well.
http://forum.xda-developers.com/showthread.php?t=976384&page=1

every version of this build has been tried. That is the part that gets me. differnt kernels don't help either. i have even used SetCPU and overcloced to try and get through some of the lag. it works, but it is only when I play games not when I need to perform uninstall or widget selection for the home pages. I use SeePU which is ususally shows my cpu strain in the bright orange (for high use). most of my processes/actions raise the cpu use to high levels. I never really operate in a green (or low) usage level no matter what the action is. I would really like to capitalize on the speed NAND is supposed to offer.

Personally I would try something else (a totally different ROM) and see if you are still getting the same results, maybe even revert back to a windows mobile rom just to see if you are still getting the hang up. Last option would be to restore your phone to stock and start over, reinstall HSPL 2.08 new radio, etc...etc...

yeah. but i did not at first. however, it is needed to stop some of the rogue processes. android.process.acore comes to mind.

I personally think this is one of the most stable builds around. I would rarely experience any lag, and if I did it would only last for seconds.

Believe me, I know. Everything is working in his build. GPS, MMS, easy to install - the works. This is why i really want this to work properly so I can use it, without the hiccups, as my daily build. It has to be something with my phone but I can't figure out what it is yet....

On Cmylxgo's build, the first time I loaded it, I had the laggy and unresponsiveness you described for the same reasons. What I found is that rebooting the system to off/on a couple of times when I first loaded the build, addressed the first initial lag and unresponsiveness. After doing a couple of reboots, I found the build as smooth as everyone says it is. I am now trying the GL Core v11 kernel and it gives an extra 300 pts to the Quadrant Score and seems to be a bit quicker than the Rafpigna 1.8 kernel that comes with the build. Also, standby battery drain seems to be a bit better with the hourly peaks at half what I see with Rafpigna. If rebooting a couple of times doesn't do it for you, I know trying another build which may not have all the bells and whistles as Cmylxgo, but it is worth a try to see if it makes a difference. For me at least Cmylxgo's stock Desire (HD)2 build is much faster and smoother than any of the MDJ SD builds I was using.

I am new to android is the Arc meant to be so laggy and buggy??

My Arc keeps crashing asking me to force close apps and the homescreen it lags like hell and it is getting worst all the time so bad that even opening my texts takes a couple more than 10 seconds... (I do have around 2000 texts though)
Unlocking the screen is laggy scrolling on threw the 5 homescreens is laggy...
Sync turned off.
No timespace widget.
Even after removing all widgets to test it it was laggy
I used advanced task killer to kill all the apps to try the quadrant test
and I only got 850-950 MAX!!
Compared to youtube videos that seem to get almost double scores why is my
Arc is slow is it faulty?
Is it because I only have 40mb of phone memory and about 500mb sd card memory left?
Will I just have to flash my phone and does that mean I will need to flash every 2 weeks???

I think you have installed some applications which caysing this problem I had this problem, then i flashed my phone again & installed apps again (didn't restore).. But i didn't installed all apps at once, i spent time & installed 2, 3 apps everyday to check if the app would make phone laggy or slow. Since then my phone is working awesome, my 16GB memory card is almost full, 400 MB internal memory is full (After root i have removed many useless system apps)... I have more than 4000 sms & there is no lag or slowness Quadrant score is 1650

the only time i experienced lag was with adw launcher and no fc's yet, other than that the phone has been fast - then again i don't have as many apps or data on my phone as you. one thing i did notice is that my lcd's touch sensitivity seems to be lower than other arc's, maybe a defect, but it's pretty maddening in addition to all the reboots i've been having. i've been reading about others that have issues with the battery staying in place and like me, the random reboots, this is my first android phone, so not sure if these things are normal or if it just the arc.

It's definitely apps.
Mine is superfast...

Apps and possibly task killing the wrong things.. you need to make sure that if you're going to use a task killer, you really shouldn't us it on Auto.. and you should make sure to IGNORE anything that is a system task, or anything which persistently restarts.. killing those only wastes battery.

Android isnt exactly the most stable os out their but if you know about the os and know its ins and outs it can not only be the fastest but the best os out there.
My recommendation is look up articles about using and optimizing the os, trust me it will do you a ton of good.

Hi,
It seams that sometimes Android must be reflashed on a Device, especially on Tmobile Devices it will fix most of the problems.
Another tip: Uninstall the update of gmaps and reinstall it, on my device it blocks login to gmail and gtalk from one day to another! -.-
Greetings
Alef

Nope the ARC does not Lag very often and i think its ur device's memory thats giving you the trouble along with that huge pile of messages .... or the Corrupt software that might have crept in ...
My advice would be to flash ur ARC ASAP and limit that 2000+ messages and u will see a difference. Avoid putting too many apps as well.
Arc is a Size Zero Lady ... Don't burden it with Heavy Foodstufff ...
Might create Digestion problems. Keep it Light and it'll stay FIT.

What do you mean "isn't the most stable"? I've been able to keep my phone on for weeks without a reboot. Seems stable enough to me.

Ok turns out I had 110 apps I deleted al the heavy ones and am down to 60 now!! My phone now got 1200 on quadrant. I dont kill any system ups or have an auto task killer set up I just kill uneeded apps before I run benchmarks?
Plus I noticed I have some orange apps that keep coming up even though I never used them... I might have to debrand and try again but my phobe is much much more stable now thanks!!
Sent from my LT15i using XDA App

chances are it wasn't the number of apps you had which was causing the problem, but that one of them (or possible several of them!) which you deleted were badly written and hogging the processor when they should have been sitting quietly in the background..

Orange is well known for screwing devices with bloatware also.

Wow!!
That's a lot of apps you've installed and most likely loads of them are badly written like iceman said; I installed a file browser on mine not long after getting the phone which would pause the whole system for up to a minute, plus battery was highly drained.
I guess this is result of massively varied hardware for one mobile OS. (Plus bad programming)
