"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.

(and yes, they used to call it "Immediately destroy activities")

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.

Close all?

There are 3rd party app killers in the play store. Check there...
There was a stock task manager...but I guess Google removed it for JB

App killer

Cyanogenmod 10.1 has a button on the multitasking menu to do that. But it's kinda pointless except to clear the list of recently used apps. Android, if my understanding is correct, automatically fills the memory with tasks so killing apps is worse than pointless since you're just causing the system to prioritize unused background processes over the ones that you use more often.

You should listen to this guy. I know you're coming from a different OS, so you aren't aware of how Android deals with memory. The system is very good at multitasking. Apps that have been idling in the background will be pushed out and won't consume resources or ramp up your CPU. By killing those apps, you force the system to have to reload and process resources necessary to start the app. Android will keep enough of the resources to quickly fire up the app, but restrict activity so that your battery is pretty much unaffected.
An analogy if you need it: Android will bookmark and close whatever you were reading. That way, you can move the book around or leave it on the shelf and quickly pick it up and continue from the last page you were on. You are requesting that the system instead just closes the book, and buries it in a box with other books, and which is located in the attic. It takes more resources to find the book and locate the page again. Just let Android do its thing. Any popular dev will tell you the same thing.
TL;DNR - Don't use a task killer, you will get far better battery life and performance if you let the system deal with system resources.

Don't listen to this guy. He used the phrase "smart one," which I haven't heard since I was in elementary school (and I thought it was un-clever and uselessly sarcastic then). He also thinks that swiping away apps from the recents menu kills them. This is not how Android works. AOKP devs will not implement a recents menu that actually does let you swipe to kill apps because it's a useless feature that does more harm than good (zero benefit, actually). Just trust that your system knows how to handle its resources.
TL;DNR - Swiping away apps from the recents menu doesn't kill them. Stop trying to kill apps; only do so if they're unresponsive.

If u really want it, aokp has this feature

Let's say I start loading a web page and quickly jump to another app before it's loaded, then when I return to Chrome the page is ready and waiting. Doesn't this imply that apps are not just simply bookmarked and closed, but may remain active in the background? I am asking, not saying btw.

Foreground apps are told that they are no longer in view, but are allowed to keep running if they wish. The OS will stop them if the memory is needed - which with 2GB is not very often on the nexus 4!

So Hung0702 was wrong on the last page when he said:

It seems as though background apps can use resources and may have a negative impact on battery. Now I have got to the bottom of this I also want a clear all button!

Yes, they can keep using resources in the background. However, they will usually not keep the cpu awake unless they have an actual background service, so they will not stop the device from sleeping. As far as I know this is not enforced, but most apps will release the wakelock when told to pause by the OS (because the app is now hidden). This means they shouldn't have much impact on battery life.
You can see what is currently running by going to Settings -> Apps and select the Running tab. The recent apps list is not the same - most will have actually closed when you hid them.

[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.

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?

Samsung Galaxy S6 Edge+ Battery Saving Tips

A phone even with killer looks and amazing features still needs a descent battery backup to support it all. In past we've seen that a few tricks here and there always tend to increase battery life. Usually that includes disabling a few apps or features. This thread is for specifically targeting such tips & tricks and sharing it all so that S6 Edge+ can live upto its expectations..

1. To start with, lets get to the list of bloatwares that can be safely disabled.
If any of you own the AT&T version, here's a list you can disable:-
AT&T Apps:-
AT&T FamilyMap
AT&T Hot Spots
AT&T Live
AT&T Locker
AT&T Mail
AT&T Mobile Locate
AT&T Mobile Transfer
AT&T Navigator
AT&T Ready2Go
AT&T Smart Wi-Fi
Drive Mode
Caller Name ID
Mobile TV
Plenti
Smart Limits
Yp (Yellow Pages)
Other Apps:-
S Voice
Amazon (I prefer the playstore version for frequent updates)
Amazon Kindle
Device Help
Live Weather (Yahoo)
Lookout
Theme Store
Visual Voicemail
2. Refrain from using any free application that has embedded advertisements. They tend to run threads in background to load adds and thus degrade the app performance and used data (so naturally consume more power too). Either buy add-free version or find an alternate app for same purpose and without adds.
3. Disable notifications from social media/news apps like Facebook, Twitter, Tapatalk, etc. Although, the phone wouldn't be that smart if all the notifications are disabled, however, keep them at bare minimum. Not everybody would be interested in notifications from all the apps, so spend some time analyzing through all the installed apps and their settings to turn off the notifications for the apps you do not need to get notifications for. There are several apps that keep sending notifications and running a thread in background which again checks internet to load the notification content. An example would be games like Candy Crush or Clash Of Clans.
4. Turn off "Send Usage Statistics" or "Help Improve the app performance", "Participate in improvement" etc settings from the app which sends data from your device from time to time which acts as a survey to improve the performance of the app. Although this is a necessary option for a developer, however, if you do not care about your granular contribution towards further development of the app, try deselecting such options while setting up new apps.
5. Refrain from using external Memory Management Apps and RAM Cleaners. They tend to run heavy background services to detect memory usage and kill applications. Trust me, you would be better without them.
6. Try using black wallpaper and lock screen. Also, always select Dark Mode if any app has theme section. This makes the pixels produce less brightness and considerably save more battery.
7. Keep GPS Location off when not using any navigational/location based apps. When the GPS is ON, there are some apps that tend to acquire a GPS Lock even though they can work without it. Keeping GPS Off will not allow such apps to request for GPS Lock. GPS Locking is a battery draining process.
8. You can use certain tools like Greenify, WiFi Automatic, etc. to automatically manage application states or phone wireless to save some additional battery. Use these only if you are lazy like me. Otherwise you can always manually turn on/off wifi/bluetooth/nfc etc etc. Also, there are tools (like Juice Defender) which can enable/disable data connective at a frequent interval which results in really good power conservation without loosing push notification.
With applying most of these settings, I'm getting 6-7 hrs of screen on time very easily even when I've downloaded 1+ GB data and 40 minutes of video chat (hangout). Not to mention the usual gaming and application usage.:cyclops:
I hope that helps. I'll keep adding if I get any (without root).

Reserved for future use!

I'm sure you mean rooting and installing all sorts of battery saving items/tweaking.
Marely rooting wouldn't bring any difference to battery life for sure!

Just tweak brightness, make sure you getting good signal and use WiFi when available, don't leave Abby of the radio on unless not using it and that shall be good I guess

Please tell me a solution if any one knows:
I open facebook and after some time i close this application by click on list tasks soft key and close it. Immediately when I go into setting > application manager > running apps I still see a facebook process running. Technically i guess this should be gone i guess and hence any idea how to clean these which i guess can improve battery life.
Update: If I have notifications turned on in facebook then yes it can still run some process even after I close it in Apps Tab but I see the same with Samsung Music Player i.e after I close it I still see a thread in "Running" Apps.

These kind of apps do tend to run a background process to check for updates. Closing the app doesn't necessarily mean that the processes will close. And I'm not even sure even if you turn off all the notification services of an app, all the related processes will close for sure, it depends. Also, if you are using apps like facebook etc, do not worry much about the battery life if you have turned off the background data usage and notification services. It will have very minimal impact, almost negligible!

Various LG V30 Tweaks and Modding - Discussion

I wanted to start an informal thread here where anyone could discuss various little mods and tweaks that any of us might be playing around with on our V30s.
I'm not talking major things like flashing a rom or rooting or anything like that. We already have super talented people that helped to make all those things possible and there are 100+ page threads about some of them. (Big thanks to all of you serious developers!)
Consider this a discussion thread for the "Tinkerers" though more experienced actual development is of course welcomed.
Personally I am always playing around with my device just to see what I can get it to do, or access or change etc. I use apps like Preference Manager, and Shortcut Master to play around and discover the "hidden" stuff that you aren't supposed to get to, or at least not yet. Sometimes this gives me a sneak peak at some beta feature or adds a setting I didn't have, or a UI tweak etc.
I figure that a bunch of you probably do the same things and thought it would be cool to have a thread just to share those little one off things we discover that wouldn't normally warrant a whole post of it's own.
Maybe you want to share what substratum build is working well for you.
Or maybe you found a magisk module that wasn't built for the LG V30 but works great (Dialer and contacts for the one plus worked great on my device)
I'll kick us off with one little tweak I never see posts about.
Using Shortcut Master I have changed some of the LG Home App settings in order to have a modded home launcher. Basically I'm using some of the features LG chooses to keep hidden. Some pics of the menu are below. Minor changes but I've had the Google screen to the left of my home screen for a while now and I don't have to use Nova or something else to get it to work.
I've never really seen a post on what all of these check boxes do, so I've played around with all of them and can report that most are minor, and some will ruin your day, so Tinkerers beware if you decide to emulate.

Here's another example of the kind of stuff I mean. Does anyone actually know what High Lux Mode does? I've enabled and disabled and don't really notice a difference.
Maybe a thread like this will help shed a little light on something we can all use.

I want to share that anyone on rom without Qlen support can co to system/build.prop, find "lge.support.lglens=not-suppport" change it to support and reboot

Can you link to Shortcut Manager? The ones I see in play store don't look like your screenshots.

It's Shortcut MASTER, not Shortcut Manager.

I've seen the "Lite" version referenced several times in the V30 threads, and it's even mentioned on the XDA thread linked above, but that version seems is no longer available -- only the fully paid version is still listed on Google Play.

That's probably because those screenshots are from older versions of Android. Or he has some theme applied.
It looks like the screenshots where it's been talked about in other threads, especially the Shortcut Master Lite.

You can still download a copy of Shortcut Master (Lite) 1.2.4 from APKMirror. It disappeared from the Play Store about a month ago - I'm not sure of the reason.

Not positive and can't test for it because I don't yet have a V30, but I would guess this toggles the phone's ability to use fullbright/sunlight/etc mode.
Brightness is usually capped below 100% to increase panel longevity; this limit is bypassed with high enough light levels hitting the light sensor next to the call speaker. Last I heard you need VERY bright light with the V30, and the high threshold makes it flicker on and off a lot; this could give some people bothered by it a bit of relief.

Swap Torpedo (Magisk Module): It flushes your stupid stupid compressed ZRAM/Swap. All of your apps will load faster and smoother.
https://forum.xda-developers.com/apps/magisk/module-swap-torpedo-run-faster-reliably-t3766883
Reasoning: You don't need freaking swap on a phone with 2 GB or more. V30 has 4 GB RAM. Never run into any issues with this. Flash and forget.
fstrim (Magisk module): trims your phone when it has been idle for more than 5 minutes.
https://github.com/GreyLeshy/magisk-module-fstrim/releases
Reasoning: Right now your phone only trims when it has been idle for hours and is charging which is almost never. You will notice the difference. Things will write faster to storage. Read and write speeds are faster in general. It's a very simple script that you don't need to check for updates. Flash and forget.
RAM Manager (Magisk Module): Reduces app refreshing significantly.
https://forum.xda-developers.com/android/software-hacking/ram-manager-magisk-t3816986
Reasoning: V30 has very aggressive memory management which works for most people but gives trouble for heavy multitasking. This is fixing the issue. Everything stays in memory until it's absolutely out of memory. Then it starts kicking things out. Flash and forget. Note: If you want to use this with Swap Torpedo you must install Swap Torpedo first, then RAM Manager.
None of these tweaks consume battery, in fact they save you battery. I used to tweak my previous phones a lot but after many tests I've realized that the V30 is incredibly optimized. No need for L Speed or Kernel Adiutor or any of that nonsense. Storage, CPU, GPU and battery performance are super optimized on this device. It even puts some flagship phones with SD 845 CPUs to shame. LG devs did an incredible job and pulling out ALL of the stops to make it run smooth. Read ahead is already at 4096 kb, no need to tweak! Storage is mounted relatime so it won't waste write and read. All partitions are already aligned perfectly. LG dedicated some space for overprovisioning so nothing to tweak there either. On a good day my UFS 2.1 storage read speed is more than 740 MB/s and write up to 300 MB/s. More than my SSDs in my computer. Incredible work by LG. Battery life is tweaked to the maximum as well and so is GPU driver performance. Do not touch those things especially build.prop. Every other tweak I have tried has introduced some issue somewhere else. This is a phone that you leave alone and be happy that the devs optimized it so well LG has people smarter than us working on these and who fully understand how the device works. The era of complex kernel tweaks and scripts is officially over.

Thanks for the tips on the other 2 but I just wanted to chime in on swap torpedo or getting rid of the swap on the V30. Doing this made a pretty big difference on my V20 but I noticed on my TMobile V30 that it actually was making me reload certain apps quite frequently. Now I didn't do very much testing with it but I noticed that when I got rid of swap if I had one of my more intensive 3D games running and I switched over to the camera or vice versa I would have to reload the app that was switched from. With stock swap settings I could switch back to the previous app (game or camera whichever) and it would still be open and ready.
Now take this with a grain of salt obviously because there are too many variables but I'm sharing my experience and so far mine has been better with stock swap settings on the H932 at least.

For those who don't frequent the Q&A section, @rollingstone321 figured out how to force quick-charging while the screen is on;
rollingstone321 said:
Ok after searching a long time I have found where lg did hide the charging restriction
Sys/module/lge_power_class_charging_controller
If you put the parameter for restricted_charging to LCD OFF you will get quick charge when also using the phone.
But Android changes this parameter back once the device goes to sleep. How can I make this parameter stay or even remove the module?

Septfox said:
Try setting it to read-only. I'm not sure if this will persist the setting after reboot, though. This might also have the unintended effect of forcing the charging restriction to happen while the screen is off, as "LCD OFF" suggests; have you tried seeing what happens if you blank the setting instead?

rollingstone321 said:
Leaving it blank freezes the phone, same with '0' or 'disable'. So LCD OFF is only option for now. But I rather have fast charge while I m using Waze in the car and be able to charge till 100% fast, and slow charging at night.
...
Seems like changing the parameter to LCD OFF and setting the file to only read did the trick.

As bolded, setting it to LCD OFF and making it read-only might make the phone slow-charge while the screen is off. Having something (Tasker, AutomateIt, etc) set it each time the screen is turned on is a better solution if you want all QC, all the time, since it'll reset itself on screen-off.
If someone wants to go digging in LG's kernel source to see what the valid parameters are, figure out the proper setting to just disable the limiter and set it to read-only, that'd of course be best.
I went digging myself using Lunar kernel, and it seems this is read and limit set based on it, not the condition under which the restriction is imposed as I first thought.
---
Keep in mind that fast-charging alone creates quite some heat, and doing it while running the SoC under load will increase the rate that your battery ages. It's hard to say how much, since there are so many contributing factors to battery wear, but one thing is true regardless: li-ion batteries don't particularly like heat. Charge responsibly!

No I can confirm what you are saying. There is more reloading because LG optimized the V30 so perfectly. You really don't need the tweaks tbh. But that is why I use Swap Torpedo in conjunction with RAM Manager. I would even argue there is not enough of a benefit that people would notice anyway but for me things like Nova Launcher run slightly smoother. It might even just be placebo and there is no tangible difference. Either way V30 is so well optimized out of the box, I personally believe it's a waste of time and resources to use tweaks even if I use them. :good:

Isn't this actually bad though? You don't want fstrim triggering 24/7? I know on an SSD that counts as writes and you only get a certain amount until you kill the lifespan.

RAM Torpedo is actually good. Just look for yourself. Screenshot of before and after.

Ok using torpedo swap, it's actually horrible for multitasking. I'll have only 1 app open, ( line chat) open chrome for a link, copy and go back to line chat and it wants to reload.
Total crap. Never had an issue till this mod. It's also the only mod I've ran.

I wanted to start an informal thread here where anyone could discuss various little mods and tweaks that any of us might be playing around with on our V30s.
I'm not talking major things like flashing a rom or rooting or anything like that. We already have super talented people that helped to make all those things possible and there are 100+ page threads about some of them. (Big thanks to all of you serious developers!)
Consider this a discussion thread for the "Tinkerers" though more experienced actual development is of course welcomed.
Personally I am always playing around with my device just to see what I can get it to do, or access or change etc. I use apps like Preference Manager, and Shortcut Master to play around and discover the "hidden" stuff that you aren't supposed to get to, or at least not yet. Sometimes this gives me a sneak peak at some beta feature or adds a setting I didn't have, or a UI tweak etc.
I figure that a bunch of you probably do the same things and thought it would be cool to have a thread just to share those little one off things we discover that wouldn't normally warrant a whole post of it's own.
Maybe you want to share what substratum build is working well for you.
Or maybe you found a magisk module that wasn't built for the LG V30 but works great (Dialer and contacts for the one plus worked great on my device)
I'll kick us off with one little tweak I never see posts about.
