[Q] Lollipop, The Aggressive App Killer

Does this even need an explanation? Lollipop kills apps like it's his hobby.
Even with only a few light (on RAM) user apps running in the background you sometimes find yourself staring at your launcher home screen that, you could've sworn, was just showing a different app a second ago.
Or the times when, after multi-tasking a bit, your phone starts becoming painfully slow. Turns out that some apps are so stubborn that they go on strike (continuously restarting) when LP kills them.
I'm sure many have experienced this. And I have seen some devs address this issue here and there. I though it would be useful to gather the info into one thread, to ease our (or my?) frustration on this issue.
What I wanna know is, what causes it exactly (why didn't it happen on KK?), and is there a solution to this? Or at some way to calm LP down a bit with his killing of innocent apps.
Thanks.

Im running 1/8 FML with synapse injected R10 kernel on my toro and with ksm and laptop mode enabled in synapse, I haven't had a launcher redraw in days. I don't have anything whitelisted either. However, the trade-off I have at the moment is I cant seem to stream videos on my stock browser. Havent tried a different browser or anything. I just uncheck those two settings and reboot and all is well, but my phone certainly works much better now, and no redraws, with neph settings for LMK
Hope something helps someone!
Thanks

Perhaps you can noobify that a bit, lol. I had to google almost everything you mentioned. As I understand it, this Synapse allows you to tweak the kernel? And this KSM settings can improve this RAM issue? Care to elaborate? And what is laptop mode?
I've read about adjusting the LMK values to calm LP down a little. Any idea though why this was so necessary in LP, but not in KK? Is stock LP 'naturally' more RAM hungry than KK?

I can try to elaborate little bit, as Ive been flashing things and researching xda a lot, but I am still noob in how/why things are the way they are. From what I gather lollipop just handles memory differently then kk did. I think that is some of the reason as to why the "recent apps" persist through reboots now. Remember, our device was not really supposed to run kk and certainly not meant to run lollipop. The developers here are without a doubt amazing in what they know and what they do for us users. A new kernel and driver was necessary to run lollipop on the aging gnex. Now, some of the issues we are experiencing is a google issue and will only seem to get fixed when they get around to it. I know my nexus 7 (old) has some memory issues and lag and redraws from time to time....not as much as I noticed with my gnex before the changes were made I stated in the above post. I recently helped my friend root and upgrade his oneplus one to lollipop and he has the same issues we all have, maybe not as bad, but they are noticeable
A lot of the questions you have, have been discussed recently in bsmitty83 kernel thread, since I asked them. There are links there as to what KSM and laptop mode are and what they do. KSM-kernel same page merging helps with RAM and I believe laptop mode helps to conserve power. A lot of these things are geared at devices with low ram like the aging gnex, but the developers have done a great job at making lollipop a daily driver. Most users I think use trickstermod from playstore to tune kernel settings, and that is ok, however, you must purchase the paid version to tweak low memory settings, which I did. However, synapse, also found on playstore can also be used to tweak kernel settings, but the kernel has to contain UCI support for the synapse app to work. Synapse has more settings available to tweak than trickster does, like KSM and laptop mode, which have helped me very much. The only kernel I'm aware of that has UCI support for synapse is bsmitty83 Full_Auto R10, because osmosis made it work
Hopefully this was rather accurate and helpful and not convoluted! ha.....im sure some more knowledgeable people will come and correct anything I said that may be incorrect, but in the meantime, read through the R10 kernel thread and see what you come up with
What ROM and kernel are you currently using?
Thank you

I'm currently using AOSP rom (by freshgimmi) and the Full Auto R10 you mentioned. I'll try injecting the new ramdisk now and see how it goes.

I noticed this issue as well for the first several days . However once I installed the new bootanimation from arter97 the issue doesn't occur anymore. Not sure if it's related but all I did was mount /system as rw and copied into the new lollipop boot animation from here: http://forum.xda-developers.com/android/software/arm-arm64-android-5-0-lollipop-t3032247

I know about this issue. It is a memory leak during boot. It is a good catch, though all you're changing is the bootanimation.zip. AFAIK, it should not affect your system's performance after boot, once your phone is up and running. My issue is a different thing entirely. I never got bootloops (that is, when not messing around with xposed).

Okay, you're right. As a test last night I switched from FML 5.0.2 to LiquidSmooth's LP ROM and I'm not seeing any aggressive app kills in LiquidSmooth.

I have got synapse up and running. I AM wondering though, what LMK settings are you using? Cause the neph settings I know of tell me to set empty app to 370, but synapse only allows max 320... If you're following different settings, could you link the post for me?

Glad you got everything up and running.....Im using Neph's settings for LMK, and your correct the empty app only goes up to 320 in synapse. There was a post somewhere where Neph said he was still tweaking his LMK values and I believe he mentioned about lower empty app to 330 or something, so I just set it to 320 in synapse and call it a day

Eliminating Scroll Lag/Jitter?

I am one of the few people who hasn't been happy with his LG G4. I love the build, camera and to some extent, the stock launcher, but one thing that irks me is the irritating scroll lag/jitter I experience in most apps. Coming from the Nexus 5, this is jarring and I want to punch the G4 in the face (I then resort to pressing on the screen very hard...it doesn't care).
I have looked and looked for a solution, but there is none. So I ask here, is there a way to eliminate/reduce scroll lag/jitter? The jitter is most noticeable on the official Twitter and Facebook apps, where scrolling causes the feed to hiccup along the way.
What I have tried so far:
- Debloated (no-root) apps and services
- Tried numerous stock launchers including Nova and Google
- Turned animation speeds to 0.5.
- Greenified some apps
- Turned on forced GPU rendering (this one makes no bloody difference)
Is there ANYTHING I can do? Appreciate the help!

I have set up where lag is and jitter is pretty non-existent.
I am rooted for one. Using kernel adiutor changed to interactive on big and little.
Using Amplify to prevent wakelocks. Greenify to hibernate apps. Powernap for battery life. Finally the CTT mod.
Unfortunately, it seems like a lot of work to alleviate (not eliminate) the lag and jitter.
Hopefully we get some good roms when all bootloaders get unlocked.

Damn, that's a lot of work. I am **** scared of rooting my phone in case I brick it, so that's out of the question.
I am hoping for some good Custom ROMS as well, but damn the phone is so powerful. It shouldn't lag at all!

My nexus 5 has less lag. True, this phone shouldn't lag, but bloat ware doesn't help. Rooting this phone wasn't as hard as I thought. I want pure Android on this phone. Give me some cyanogenmod or cataclysm and I will be happy.

Your favourite rom

i'm thinking of switching from stock(currently mm .144) to cm14.1, can you give me cons & pros comparing both roms? well, in terms of ui, battery drain, apps & games performance/compatibility.
Tapped from my Zenny 2 using XDA Legacy

I agree!The only thing that prevents me from enjoying it is no Radio and no Cover support(the rest of Zenui apps are working)

Also there are some incompatibilities with pixelmaster

I don't use stock so much because I'm more attached to CM/AOSP than stock.
As for performance, it's blazing fast. My 1080p 10-bit videos could play smoothly, even with CPU clock limited to 1333 MHz. I test PPSSPP games and it's same as CM13, but it performs a little bit better.
As for UI, CMTE is absent right now. Substratum is incompatible. So, I leave most things unthemed. One unique but useful thing I found is Power notification tuner inside System UI Tuner > Other, which could be used to force set an app's notification's priority.
The only thing that bugging me is Opera Max notifications, because there's one data control panel notification and one empty and useless space from Opera Max. Disabling it from the app's settings doesn't get rid of notifications.
Games compatibility: I think I should open a new thread for CM-14.1 games compatibility list, that also include Ingress which has started to working.

I see, another question, how much SoT you have from moderate to heavy usage?
And btw, do i still need to install xposed for its features like gravitybox or it is already integrated on the rom?
EDIT: I think for now i'll just stick to Stock MM as i saw on the CM14.1 Z00A thread that there are cases of battery sudden drop to 0℅, sensor bugs, etc.

1. Probably I would have to charge my phone until full, then. However, I attached my session from 87% to 9% recorded by AccuBattery, with moderate usage on browsing here and there, doing update to 12/11 build, then playing a PSP game.
2. Xposed is absent for Nougat.

Sudden battery drop: I feel it.
Sensor bugs: Some devices affected.
Other things: Unimplemented/WIP features, GPS bugs (I don't care :v)

The first is CM14.1
The sencond is stock 5.0 - always stable (except with Facebook apps:silly
And btw, i hate stock 6 the most, it even drain my battery faster than CM13/14.1

Average sot for every rom on this board with average usage is 4 to 5 hours. I've been on here a long time , and have read through pretty much all the threads . Especially the Rom ones. And it is pretty much universally 4 to 5 hours. Of course it will all depend on what you are doing.

No xposed for nougat? Damn, i will wait then

Xposed modules

anyone knows any good xposed modules for k430 mtk?

Depends on what are you looking for...

anything that could boost my android performance (or battery saving)
anyway, anything is good, as i want to test the xposed on my phone
EDIT: im a pure noob in this things

Xposed modules dont help to improve performance much but for battery i suggest Greenify (it also works without xposed but there are some extar options with xposed)
Amplify (greenify and amplify combination is the best)
Bootmanager
Gravity Box (I DID NOT USE IT ON LG BECAUSE I DIDNOT ROOT MY PHONE YET BUT USED IT ON SAMSUNG SO BE CAREFULL BUT I SUGGEST NOT TO USE IT AS YOU SAID THAT YOU ARE A NOOB)
Apart from these you can use also use:
One click video downloader and one click youtube extension.
Youtube background playback.
Virtual sensor
Flat style status bar icons

60FPS PUBG optimisation app.

PUBG doesn't run well on our low-end device especially with MIUI(talking about 2GB RAM variants). But custom ROMs have made that possible. Here is an app that'll make the gaming even smoother. Literally smoother. I've personally tried it and works surprisingly. Download the app given below and set the configurations as posted in the screenshot below.
https://play.google.com/store/apps/details?id=eu.tsoml.graphicssettings
Update: You can control the graphics as well.

Yes, i use that apps too, its so worked for me. The game run smoother, but its make your phone 45°C(thats mean hot)
