"Don't keep activities" - anybody use it?

Love the phone but a few times the launcher has redrawn after exiting an app because of most likely memory issues. Anybody using this option? Assuming over time this would keep more memory free and reduce this issue. Any thoughts?

This is one of the reasons why I don't like that Google included these developer options pre-installed on this phone. They're developer options for a reason, we can install them if we need to.
This feature is designed so that developers can test their app to be sure that data is properly saved when is no longer in the foreground. For example, if a user receives a phone call or jumps to another app, the app needs to do what is necessary to save it's data. At times, Android can kill a process in the background. If the user plans to go back (perhaps they finished the phone call), they want to see what it is they were working on last. The developer is supposed to handle this case by rebuilding everything as it was before (to provide that seamless experience for the user when switching between apps).
This debug feature helps us test that it works.
For the average user, all you're really more likely to do is slow down your apps. As they will have to rebuild themselves when you resume them, and you may even open yourself to more quirky bugs (for those apps that didn't properly test the above scenario).
So please don't enable it unless you're doing it for development purposes. My 2 cents.
*EDIT* Here's a page from the Android Dev Guide justifying my explanation:
http://developer.android.com/guide/developing/debugging/debugging-devtools.html
Immediately destroy activities
Tells the system to destroy an activity as soon as it is stopped (as if Android had to reclaim memory). This is very useful for testing the onSaveInstanceState(Bundle) / onCreate(android.os.Bundle) code path, which would otherwise be difficult to force. Choosing this option will probably reveal a number of problems in your application due to not saving state. For more information about saving an activity's state, see the Activities document.

Thanks. I turned it off. Did notice some bugs while on. I just wish with 1GB of RAM the launcher wouldnt have to reload. Hopefully things get better. Might just be my apps but it happens quite often when leaving the browser.

weird.. how many widgets do you have on your launcher? the more widgets you have, the slower the launcher is.
Have you tried another launcher? The stock launcher has never been known for being fast and efficient, although I haven't had any issues with it (whereas I'm a LauncherPro fan on my other devices).

I have quite a few Widgets but nothing too crazy I don't think. I use LauncherPro on my other devices as well but I love this new launcher so I'm going to stick it out. Like I said the most common task that causes the issue is when I'm using the web browser and then come out of it. Otherwise its been stable. I've noticed the same thing with Honeycomb on my Xoom so it might just be one of those things I have to put up with.

i'm also noticing some redraw and occasional lag when hitting the home button.
I'm hoping that CM9's custom launcher will have an option to lock it in memory- that may increase the performance by a lot.
also when replacement launchers like go launcher start optimizing more for ICS those might be good options.

Have you tried converting your launcher into a system app? You'll need to use Titanium Backup Pro or something similar to do it for you, or simple copy the APK into your system/app folder... Really sped up my launcher!

Thanks for clarifying the meaning of "Don't keep activities"

my razr xt910 cannot be counted upon to run smoothly with all the apps simultaneously running and forcing itself to go into reboot. i then fancied an iPhone single styled system (as compared to Android multi-talks) cuz iPhone looks robust and responsive. all the killer that claimed to do the job looked more of a farce and then when i stumbled upon the destroy activity i was like OMG. srsly b4 using it I've only got just inner 100mb of ram, after using it i have a whooping 400mb ram. UI appears faster and all. regarding the relaunching of apps and battery life being used up. i think I'll start to worry about it on a later date. what say any body. ooh yes to add on, even after i deleted 40 apps on my phone it still hanged like fcuked. i guess i can reinstall them back again and not have to worry about it. btw i can't seem to root my xt910 for nuts so i can't custom ROM it along with all other fanciful mods that i hear about what others did to their phones.

[Q] Anyone else notice some lag after the first few days? need help if you have!

So i've only had the phone for a few days and started noticing lag mainly in the settings yesterday.
It was buttery smooth the first few days until yesterday. I'll try to create a clear description of what is happening.
Everything in terms of hitting applications, sliding/switching pages, and browsers seems smooth but I'm getting doubts since settings have started lagging. So as of now, the settings menu is where I really notice the problem. What happens is I would press any of the choices such as display, sound, storage, etc and it would light up blue as a sign that I pressed it. Basically, the blue lighting stutters/lags as it turns into a deeper color and fades away proving that there is some lag. That itself is very irritating on such a powerful phone. The page also lags a bit as it's opening so it's obvious that it does lag. I don't understand why something as simple as settings might be causing this?
have any of you guys noticed this? I tried clearing ram, restarting phone, messing with dev options by changing animation and something else to .5x while enabling "force GPU rendering." I'm running stock touchwiz on baseband T889UVALJ1 if that helps. Keep in mind i'm not really tech savvy so try to suggest things in an easy to understand way please.
Any help is greatly appreciated and I hope you guys can help me fix my problem!

Been using it for the past 1 month plus and I do not have any lagging issues. I am on stock rom as well.

No lag either, been using the Note 2 for 2 months now. Check your apps with BetterBatteryStatts (too many backgroundservices runing).

No lag either. Did u install some crappy apps that run backstage

Thanks for the replies so far and before I spend some money on apps or what not, is there any way I can post a 5 second animation of what is happening? Kind of like a 5 second gif of my screen? A mix of a screenshot and video so like a screen vid? Are there are any apps that can do that(preferably free). I'll try to find an app that can do that in the meantime and will edit if I find something useful.
Edit: No idea what this is or how it ended up on my phone but could this be the culprit? https://play.google.com/store/apps/details?id=com.tgrape.android.radar
People say it's bloatware and s-suggest from samsung but i'm not sure why it would be shown as an app on the play store website

I have noticed the phone can lag a bit if you have a heavy live wallpaper running.
Just sharing my thoughts on this

did you modify anything? no lags on my N2.

normally i'd say if you leave your phone on for a few days in a row, clear the memory every once in a while (press and hold home, go task manager, ram tab, clear memory) or reboot it, just so you dont have anything residual in your ram.
when android sees that you have 2gb of ram, it doesnt auto kill as many apps as it would if you were to have only 1gb of ram (my note 1 autokilled sooooooo frequently that it was annoying), so your ram ends up getting filled with some apps that you only used once in a while.

I wrote that I tried clearing ram and restarting phone but it didn't help. Thanks for trying though

Yeah, I get a bit of lag here and there, specially if I haven't cleared running/background apps in a while.
I just do it from the task manager, and also check out what apps are using the most battery, and possibly therefore are some of the likely culprits.
I actually use this app called Carat, which is an "Energy bug detector app" (whatever that means), but it helps identify apps that are draining the battery, and incidentally, partially contributing to the lag.
Also obvious thing like live wallpapers or touchwiz in general (including all the 'special' Samsung features like smart rotate, smart stay, smart motion) probably add to it to. Nova launcher and a static wallpaper might help.

I'll try to post a video sometime soon showing the lag. It's not serious lag, but it does stutter and lag a decent amount compared to my first few days which is what sucks.

This happen to me..If surf net lag this could help..check your network setting.
if your SIM card is 3G,set it to "GSM/WCDMA AUTO MODE" instead of LTE..
Hope it help

Well I have a T-mobile Galaxy note II. It should be the 4g LTE variant but lte is not available yet. I think it is the n7105

You can try enabling Force GPU rendering in developers options. That usually helps with that, or at least it seemed to in my case. Report back if it actually helped

quick update:
I found a vid and my lag basically looks like this http://youtu.be/0qyijcTeHcU?t=2m27s
Look at when he clicks on display, there is clearly some lag even if it is half a second - 1 second. I'm almost certain that my lag is even worse than that, but not by too much. It's just a pain in the ass after the first few days. Would flashing a custom rom like jedi X 7.2 help out with this since it's running a bravia engine?

Screen Flicker - No OC or UV

I have not had this problem at all...until maybe a week or go, when it started.
I have screen flicker, sometimes quite bad. I thought I read somewhere that GPU settings may have something do do with it.
Thing is, I haven't changed any settings, or kernels. I'm no what is listed in my sig, and have been for quite a while.
Any thoughts?

You could try disabling HW overlays under developer options in the settings menu.

Disabling hw overlays won't help (much anyways). Turn off auto brightness. Just set your brightness to a usable level. I didn't notice a single flicker the day I turned off auto brightness. The only tradeoff there is you're gonna run through your battery a little more quickly in lower light levels. Wasn't worth it for me, but whatever makes you happy.
Sent from my SAMSUNG-SGH-I747 using xda premium

Neither is a go for me.
I never use auto brightness; I've tried both having Disable Hardware Overlays set and not set.
It's strange...I never had this problem until recently.
But, another thing that seems to be the case: I"m not sure it's happening in any app other than Samsung Email.
...
Just went and tried something: opened an email and scrolled in Samsung eMail, and it flashed. Did same in GMail, and it didn't. Maybe it's just something about a recent upgrade on that app. Maybe I'll post a topic on that app and see if anyone else is seeing it.

It's listed in my signature. Stock/Rooted.
I do have an update: I also was having pretty severe flicker/flashing when reading in Aldiko.
Last night I did a TWRP backup; factory reset; restore Data partition. Flashing is improved quite a bit, but still there.
So again, it seems it is happening, for the most part, in just a couple apps: Samsung Email, and Aldiko.

Sorry. Didn't mean to offend. I didn't know sigs don't show up when viewing in mobile. I put the info in the sig in order to prevent people from having to ask, and to prevent from having to type it with every post. I appreciate your telling me it doesn't show up in mobile apps. I never use mobile for forums...typing is to laborious.
IN answer to three, yes, have tried different kernel, although it's been quite a while.

It's ok.
I've had this issue on AOSP ROMs. Only way out was to change ROM.

Whatsapp and whatsapp+ resolution problem

Has someone here the same problem like me? Every time if I open whatsapp/+ the resolution changes. Also if I change between chats, it gets every time smaller and smaller. It looks like it goes on tablet mode. If I delete my ram and start whatsapp again, it gets normal but than after a close or a switch of the chats, it gets again smaller. This Problem is on whatsapp+ now. On Stock whatsapp I haven't this problem, but there is also a resolution problem. like if I press menu button, the menu window is only on the half the other part is gone. I will post some screens tomorrow. Let me know if you have the same experience like me.

Try installing xposed framework and then installing the AppSettings module, or it was called something similar. There you can set specific pixel density/resolution for Whatsapp. That way I fixed similar problems with Flipboard on my chinese tab.
Good luck!

Hi, i recently updated to 4.4.2. KK (I went pristine as well) but when I reinstalled WhatsApp it looked different AND I can't send mp3 files anymore! Any idea on why?

Thx man! That fixed the half problem. It's much better now. If I change the screen (dp), the resolution jumping is still there. Only if I change the DPI, the resolution stay fixed. The DPI on the Ascend P6 is 312, if change it to 312, its all to small (very small) and the background wallpaper does no match. I've changed now to 349 DPI, this looks perfekt for me.
The first picture is with the Appsettings mod, the DPI is 349. You can see, the menu is lost in the edge.
The second picture is stock whatsapp+ with a theme. The last picture is also stock whatsapp+ with a theme, but here I've changed the chat after I made the second screenshot.

[Q] Slow Camera Gallery

Anyone else seeing a really long lag when trying to load the gallery from the stock camera app? Checking a shot takes way too long; easily 5-6 seconds. It's driving me a bit nuts. And yes, I could use a different camera app, but the stock on is the camera it loads from the lockscreen, which I actually do a lot. Anyone else experiencing this, or possibly know how to fix it?

I experience the same.. and I don't have a resolution.
I just figured it was software properly releasing the hardware to something.. drivers letting go of whatever they hardware they were holding on to.

You are correct. I don't think you can make it the default gallery for the camera app sadly.

Love QuickPic- been using it since Note 2. I'm not seeing any lag though. I've got the pics going to the external sd card and it's a fast card- maybe card read/write speed matters here.
Another thought is maybe there's a file that's corrupted in the folder where the pics are.

I have found that if you have the option set to view picture or video after each shot it's almost instant, and the gallery loads very quick for me this way.

That kind of works, but I don't want to have to review each picture and then go back to the camera each time. I have to believe that Samsung is working on this, as this is a huge consumer-facing issue, though I haven't heard much talk about it.

Have you tried QuickPic out? I know it doesn't load from the lockscreen but at least that will tell you if it's an issue with that app specifically. I was also thinking it might be card-related-- is your micro sd card a fast one?

Turning off online photo locations and using .nomedia files to stop the gallery from scanning unwanted folders helps too.

Well yes...because it doesn't have to scan your external SD card. Obviously anything saved to the internal will load faster.
