"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] Having issues with launchers...

Just got my galaxy s3 today. Been messing with it sense. Unfortunately i've had issues with some launchers and I don't know why. Apex/Nova/Holo have all been giving issues in the terms of putting down Widgets at the home screen. All three will tell me that there isnt enough room on the page for the widget when that same page is completely blank.
Another issue i had was super lagginess. I haven't rooted yet because im still kinda noobish and i dont want to do anything derpy to the phone. And i wanted to give touchwiz at least a little bit of time. Aside from that though ive been installing and un-installing launchers like mad and im still getting a bit of lag from switching between pages for an example. Ive got scroll effects turned off and speed nearly all the way up (or low in Apex i think) and its still feeling sluggish.
Was wondering what recomendations you guys could give. Like i said i want to stay stock for a bit...at least until cm comes out

When you reboot the phone, do you get the prompt that asks you what program you want to use (for the launcher)? Select your desired launcher, and press Always.

Yea I get that option and ive placed it for my holo launcher but for whatever reason apex and nova were giving me issues like lag and starting to fc things. Was just curious if any one knewbl what was up. Any good launches you would recommend?

Don't quote me on this but I believe you have to make launchers a system app if you want widgets to work correctly.
At least, that's what I heard. I could be wrong.
Its worth a try?

I use nova on my phone and tab and have no issues. Might want to try and do a full wipe and start from scratch

Yep, full wipe is my suggestion as well.

Going to ask something slightly noobish but how do I make one of the launchers a system app? Im still stock at the moment so im trying to figure out whats going on.
I did a full wipe just now and its sill giving me issues that there isnt enough room on the page for the upload of the widget. All im trying to do is upload a stock digital clock widget and its giving me issues in both apex and holo. Is it because they might be touchwiz widgets and the launchers aren't recognizing them? I dont know if that could be the issue but like I said im still stock. Now that i look at it though I may have to root my phone sooner than I wanted. Been on battery for three hours and im already discharged at 51% grr..:crying:

Read this.
Q: I can't add widgets to my homescreen from the Widgets tab of the drawer. Help!
A: In order to use the in-drawer widgets feature, you have to either enable the Root Helper from advanced settings or install Apex Launcher as a system app (instructions below), both of which require root on your device. This is due to limitations of the Android framework, so there is no way we could change this requirement. If you have just installed it as a system app and still cannot add widgets from the drawer, please reboot your device and try again. If you do not have root access, you may still add widgets from the system widget picker. Just long press on the homescreen and choose "Widgets" from the popup list.

[Q] Note 8 VERY slow... now

I've had my 8 for several months but now it's starting to slow down. I have done everything except a factory reset (because thats just a pain in the ass) but it is still slow. Short of the reset does anyone have any ideas? Thanks!

I assume your battery drain is normal, or has not changed since the slowness has happened.
You have not stated if you rooted or custom ROM has been installed.
I found a few apps will do this time to time... depending on when they update. I always monitor my apps so troubling apps are always reverted back to their previous version.
You can use security 360 to monitor your tablet... It is a very good antivirus with some nice built in features. One is memory speed up and usage.
Basically it lets you know what apps are running in background, and releases them to speed up the tablet. I like it because it is like having 3 or 4 apps all into one and does not hog memory.
You can search the Q&A for battery drain if you have issues with battery as well ... there are many threads, so at least one will help. The lengthy threads have some good info near the end... as I try to help using simple methods that work with stock ROMs.

If not rooted, do so and you can eliminate apps that you don't use and that suck up RAM. You can as well move programs to an SD Card to increase the memory available.
Additionally, rooted or not you can go in and clean out the cache of all your apps. They build up over time.

Went to Best Buy and talked to the Samsung rep and he had the answer! First, get rid of SPB launcher then use Clean Sweep (in the store) to get rid of bloatware. Fast as Hell now! App only works on non-rooted I think. But it DOES work! Thanks for the help!

SPB launcher??? It must have been rooted. I have a mostly stock ROM... never had speed issues, but it is all in the choice of apps I install.
Given that many apps are developer driven, and from my experience with developers here on the forum, makes me cautious about installing apps. I install only what I need and does the job cleanly. Sometimes the best apps are buggy when being updated to run 4.4.x, as I seen that a lot since Xmas. Though May has been a good start for the year... many apps have been sorted out, but still iffy as there are thousands of apps to choose from.
I places a thread, and an answer to battery, and apps disabling in a simple and minimalistic method. If anyone is interested, they can search for posts by me... they are within this year.

You should not have needed to uninstall SPB unless you already had a whole bunch of apps. I have 200+ Apps with no issues.
Also Clean Sweep is a nice app, but you can do this already without the added app. Open you Google search, look at the bottom left hand tab, open it and you can do the same thing.

Nope. Not rooted and the launcher worked fine but apparently it slowed the system down. Now it's smokin'.

Greenify still worth it non-root?

My first non-rooted phone, and it may be that way for a long time! What's the consensus on using Greenify without the root features? I'm shocked at some of the lag issues with stock contacts app, and dialer. Oh well - Greenify - yay or nay?

I use it, and my screen on time on MK5 is a bit over 5 hours. Not everything can be successfully Greenified, but I Greenify a lot of background running system apps and it makes a difference. If nothing else, Greenify Facebook or other background uploading services. That's what really kills your battery life.

Have this phone for about 2 weeks and absolutely love it... very smooth and snappy ... but I'd like to see it root ... love this phone

So cool! Should I give it a shot or has it not been approved by the Note 4 masses yet?

Many ppl use this on their verizon and att note 4's seeing as how we dont have root to disable all these things another way.

Question A greenify app for OPO Android 13

Hello everyone and a happy new year to all!!
I run a business with my phone and used greenify to close all background apps (ig, fb, Twitter etc) from opening up and distracting from business text and email notifications popping up. And also saving battery.
But obviously I learned the greenify isn't being updated for a while and it's a nightmare to easily close certain apps I need closed. I still use it but it takes like 10 mins to close apps that I have chosen to be hibernated.
Is there an app for android 12 that I can use that actually works and closes my background apps in 10 seconds?
I wholeheartedly appreciate any answers!
Thank you all and please stay safe.

I use Ice Box to freeze and defrost apps when I'm not using them.

Thank you for your reply, I'm assuming that you're rooted?
And also when I do greenify all the apps (which takes forever) you know how when you want to share something, you hit "share" and Android opens up all the suggested apps to share with, that causes all the apps to wake up, does that happen with your method?

Hi, servicly is a good alternative for greenify, but for this to be operational android phone must be rooted..

Thank you, I was not trying to go the rooting route, I used to root and install nightlies like a mad man years ago. But now I'm out of the game. Just one question with that. Do you lose Ota updates rooting? Thank you very much.

No, freezing the app disables it until you launch it again. The other suggestion of Servicely may fit your needs better. Both require root.
Mikedeez! said:

Click to expand...
Click to collapse
You still get OTA updates when rooted, just have to do an extra step after installing to keep root. Install OTA but don't reboot yet, then install magisk to inactive slot, then reboot.

Oh I see, if I root then get the Ota it'll disable root and will have to root again. Got it.
But are you 100 percent sure that "share suggestions" don't open up all the apps? Because greenify froze my apps too but like I said before the "search suggestions" would reopen them.
And also does servicely and the other apps freeze quickly? Unlike greenify now that takes like 5 seconds each app to force close. Was so used to greenify it was so easy.
I really do appreciate your help and patience

For my part, i use a battery monitor app called BatteryGuru which has an option for doze configuration which puts apps in hibernation and your device in deep sleep same as the shortcut for sleep in greenify.

Hey, thanks. Do i need root?

Try Naptime.

BatteryGuru needs a set of permissions achieved with adb commands. There's how to guide in app.

Both icebox and brevent are good to go, neither requires root, you need to do adb or wireless debug though, easy to use and I also recommend Shizuku which helps a lot for non root but high previliege actions

Hello, and thank you again. But it seems like these apps are for doze. I'm more looking for an app that "force stops" apps. Preferably like a batch force stop like greenify did.
I want to pick and choose which apps I want running and which I don't.
Thank you and happy new year

Icebox works great with root. Never tried it without. It completely disables target apps like they aren't even installed on your phone. They don't show up in the share menu. The free version tackles 10 apps max. For more, you need the full version.
What @terlynn4 said about rooted OTA is correct, with the qualification that you will need to download the full OTA (4gb+), not incremental.

I'll definitely dabble again in rooting if needed be. Had so much fun with it since the first Android. But then just got older and busier and stopped sadly.
Now with this new oxygen colorOS crap it's a nightmare.
Does anyone know why greenify technically DOES work but takes so darn long to go thru its cycle on Android 12? Or is it just our OS that's like that?

It was definitely all good until Android 12. Now even the other apps that were like greenify do the same thing and take forever to cycle thru the apps and force stops them. I wonder why

Maybe because android 12 already "optimizes" apps and has a background app check that shows which app are running since when. Maybe not an expert here.I
know this is off-topic but If anyone is interested in a good close to stock android 12 source custom rom, i highly suggest StagOs 12. It spoofs a pixel 5 so you get all pixel 5 features. I like it very much.

I went on background check and there's only 2 apps there with a date that says March.

Dumb question guys/gals like I said since I haven't rooted in a looooong time.. If I root will it erase my phone? And if so what app do I use to make the best backup so I can keep my apps and data associated with it before I root. Love you all for the help.
