Still laggy after usb debugging enabled

Hi all,
I have had my DHD for abit over a month now and love it, although it is very laggy now. The camera is attrocious (order of 10 seconds or more to take a photo), the contacts list takes about the same amount of time to load up. In general opening apps etc. is very slow.
This is after i have already enabled usb debugging.
Is there some way i can work out whats causing this lag? and fix it? its extremely annoying and dissapointing.
I already have a couple of task killers that clean the cache and kill apps every 20 min or so.
Any help is much appreciated.
Cheers

I'm by no means an expert, but I do know (from experience and reading on here) that using task killers is the dumbest idea ever on Android.. Not only does it not make any sense, as Android manages the ram better than any task killer is able to, it also sucks battery and is actually often the source of MORE lag..

I agree. However, I find that running a task kill right before attempting to shoot 720P video removes the occasional stutter-bug with afflicts the DHD from time to time.

Don't keep task killers on auto mode . Use it when required

solution:
uninstall all of the task killer apps
let android do the task killing itself

What about stopping an app from starting up at boot can anyone recommend anything?

which processes cause the lag?
Very often such a lag may be caused by a process running wild. Please use a task manager to verify which task uses a suspicious amount of CPU! There are plenty of them, I can recommend SystemPanelLite by NextApp as a start.
Please take into consideration that Android is designed very efficient and aware of low memory conditions (and the DHD has over 750 MB!), and that it should not be reasonable to use a task killer at all, despite the situations where a certain task has gone insane, which has to be killed then.
Best regards,
arpy

I stopped my DHD's lag when I stopped using live wallpapers. Seems to have done the trick for now.

task killer

should i use task killer or not. some say it slows down the mobile or eats more battery.. pls help

Just don't use it. There's an app called watchdog which works better, according to me.

Are this apps necessary to free memory or its just a gimmick

No, Android will manage all of your memory for you. You do NOT need a task killer.

AWBob is right.
Task killer is not needed and actually can give the opposite effect from what you want it to do.....
Android is capable to manage memory (in addition, DHD has a lot of memory )

I am no technogeekexpert
but Advanced Task Killer works just fine for me. Just leaving everything running slowed my Evo down enough to make it a satisfying. and feasible option.

Don't use it. It is not needed. Check the detailed info here.

Maybe this article helps you
By default, every application runs in its own Linux process. Android starts the process when any of the application’s code needs to be executed, and shuts down the process when it’s no longer needed and system resources are required by other applications.
A content provider is active only while it’s responding to a request from a ContentResolver. And a broadcast receiver is active only while it’s responding to a broadcast message. So there’s no need to explicitly shut down these components.
Activities, on the other hand, provide the user interface. They’re in a long-running conversation with the user and may remain active, even when idle, as long as the conversation continues. Similarly, services may also remain running for a long time. So Android has methods to shut down activities and services in an orderly way:
An activity can be shut down by calling its finish() method. One activity can shut down another activity (one it started with startActivityForResult()) by calling finishActivity().
A service can be stopped by calling its stopSelf() method, or by calling Context.stopService().
Components might also be shut down by the system when they are no longer being used or when Android must reclaim memory for more active components.
If the user leaves a task for a long time, the system clears the task of all activities except the root activity. When the user returns to the task again, it’s as the user left it, except that only the initial activity is present. The idea is that, after a time, users will likely have abandoned what they were doing before and are returning to the task to begin something new

You don't need free RAM, this isn't windows it doesn't perform better with free RAM, if you kill tasks to free RAM, android will probably re-open them again. Task killers will break your system, young children will laugh and point at you for using them, and support for any problems will consist of remove your task killer then come back and talk. Don't do it kids you know it makes sense

HI,
As I don't want that children laughing at me and throwing some little rocks on me let me ask THE silly (or not ?) question :
is autokiller* as bad as the other "taskiller" ?
I've read that this app was "not like the others" but hey... devs who want to stick their apps in my phone are a bit like mens trying to stick something else .. somewhere else :
"I'm really not like the others baby..."
so... where is the truth ?

autokiller doesn't actually kill anything.. it allows you to change the default values set in android's internal memory management. it's more like an interface for android's internal memory manager.

I've replaced ATK with auto killer and I think that it is a positive change. My device feels faster en it looks like it runs smoother.
I think this is a great thread which helps me beter understand the memory handling within Android. For now auto killer looks like a charm to me, and has more benefit than ATK.

Using Launcher Pro, easier way to close apps faster?

I heard App Killers use memory, so I was wondering is there a way to get a shortcut, or a way to tweak to put what apps I want terminated and that I use on the go all at once or all in the same list? It's annoying to go into settings, then applications, then run and scroll through each one and force stop lol .

Don't force apps to stop. If it's not in use, it doesn't matter if it's in the memory.
Linux operates differently. In Windows you could use up a bunch of memory and it slows things down, but until you get to a critical level your Atrix isn't going to slow down. It's better to let it manage itself, otherwise it will simply start the task over and pull it to the foreground even though it was using no resources happily in the background.
Only close apps if they're erratic or if you want to clear memory for something hardcore like a PSX or N64 emulator, etc.
Trust me. I don't kill apps and used my phone like some sort of newb, but it actually works way better than when I try erratically killing apps all the time.

so even if its in the running tab say like browser and gmail, and say an app that uses gps and data and I close it but don't force stop it, it won't do a big deal on my battery? Sorry im new to all this, very new.

As soon as apps like Maps are out of focus (not immediately running on your screen) the GPS will stop searching. You will notice that Android is more than capable of handling it's own memory management. Just relax and let the OS do it's job. Some things you're killing with a task killer will just be immediately reopened by Android, as it's being referenced by another app. That will kill your battery much more so than just letting Android remove resources from a running app.

This brother is right!
Yep, it's kind of a strange concept. I was so skeptical and yes, sometimes I look at the stuff in the background and still get suspicious. But the battery life and performance speaks for itself. After months and months of it pestering me, I finally submitted. I only kill tasks before running high end console emulators or a couple other apps that require a lot of juice.
It's definitely something that takes time getting used to. I've had an Android for almost exactly a year to this day and it's still a hard concept to grasp. As long as you're not running some crappy program that was poorly coded, it otherwise does a great job.
First Android OS was 1.6/Donut and that wasn't nearly as good as Froyo and Gingerbread. HUGE difference. I'm using an Xperia X10 because my Atrix is currently broken, but I've got CM running Gingerbread and WOW. It's like a completely different phone!! Even just the stock Froyo handles tasks much better. The Atrix is damn near flawless in comparison too.

I like Watchdog, http://goo.gl/c4On5. It will tell you if an app needs killing. You can even put a widget on your screen and watch how many apps are running, how many are idle, and what % of cpu is used.

Also,the definition of lag varies among people.

have you ever used a mac computer?
Just because ram isn't showing free does not mean it isn't there. It keeps apps background but using no actual ram or cpu so they can be quickly opened. If it needs the ram it is easily freed up for other things instantly.
Free ram sitting there doing nothing is actually a waste on a linux based system

Of cous I have used mac,my home has one mac book pro.
I understand your point.Memory not free doesnot mean it cannt be used.
I am concerning the case that heavy use.
Even system freeze( correct me if I use this word wrong) those low priority apps,however,in such case,too much apps to be freezed will make laggy.
So,try it yourself,open msn talk pro,facebook,xda app,browser,poweramp with playing flac,dsp manager and large game(Heavy use enough?)
In the game,switch back to launcher,wow,shouls be laggy(Sys just do what it supposed to do.
Sometimes the memory manage mechainsm can not been done within in a short time,killing some non-restart may make you feel less laggy.
Compare the smoothness when the free ram is 30mb and 130 mb,give it a try

for the last time android handles its RAM well, free RAM is completely wasted, it keeps apps running so you can quickly re open them...its called multitasking.
If a app (like a game) is opened that needs alot of RAM the manger just kills some apps to free enough RAM for it.
There is no need for free ram at all its doing NOTHING

It is well known that most automatic task killers actually cause poor performance and battery life because they don't allow the OS to manage itself properly.
Task killers do have a place in killing errant processes, but never automatically.
Remember, just because a process is "running" doesn't mean it is consuming any CPU cycles, and as has already been mentioned, free RAM is wasted RAM.

I do not agree
If free RAM is wasted RAM, then why does phone get fast and more responsive when you clear RAM from (default) task manager ?
It means free RAM is doing something.
If free RAM was wasted RAM, phone should be always running snappier with everything kept in the memory. But it does not.
I never used any third party task manager though, but tweaking LMK always yieds better performance. That means default memory management is not so good.

If your device it slowing down when less ram is free then you have a rouge app taking up processing time, its processing time that slow down the phone NOT free ram, when a app is 'running' in the background it shouldnt be using any processing time however some rouge apps do not manger this well at all and keep running processors

I do yes, sorry being dyslexic is never good on forums

It's not needed. Consider the RAM as some food. The food not eaten is just wasted food. Unused RAM is just wasted. When you run an app or game that needs much more RAM, some other apps are killed. Android manages it's RAM really very efficiently. Specially on note, I never have to use any app killer.
Edit: Task killers do nothing but use more CPU and decrease battery life. If you kill 10 'good' apps with X task killer, and then have to open them again, you are doing nothing but using CPU cycles and battery to reopen the same apps that you closed. You walk 10 miles and then come back from where you started for no reason and again walk the same 10 miles just consume more energy, apart from making you look like a complete fool. Do not use task killers. Just check if you got a bad app.

But when you kill these "not used" apps the system will have to reload from scratch when required consuming more CPU (and battery) most apps task killers say are running are mearly cached. Read up on this as it is different from running. Android is not windows!
