[Tweak] SuperCharger-Maximum MultiTasking

Alright ppl, here is another tweak.
This one is brought to you today by zepplinrox (creator of V6 SuperCharger)
Linky to the SuperCharger-Maximum MultiTasking
** In a nutshell **
This tweak makes changes to the services.jar. It basically allows you to run more apps in the background and apps won't automagically get killed as often. Allows the phone to switch between apps a lot faster.
I have so kindly gone through the process of modifying the services.jar from BrokenOut2.0 and have packaged it in a flashable zip (found HERE)
As always, I am not responsible if your device does not like it, gets sick, or dies. But if you ask nicely, I might be able to help fix it.
Make a backup!!!!!! I will post an uninstall zip shortly.
1. Reboot into cwm
2. Flash zip (will wipe cache and dalvik-cache)
3. Reboot
Enjoy kiddies!!!!
DOWNLOAD
For those who do not like living on the edge... UNINSTALLER

If apps don't get killed in the background, then wouldn't the phone run out of memory, thus causing it to reboot? And wouldn't it lag the phone overall?

In theory yes, but as zepplinrox states in his thread, (not a direct quote) "Minfrees are absolute".
Android allows a maximum of about 15 apps in the background and this tweak ups the limit to 70. Plus android kills apps on a regular just cuz it was sitting idle too long. Also with this tweak, the time to kill background apps has been increased to about 24 hours. And yes, we only have so much ram, but when your minfree values are reached, the service is invoked and apps are killed.
I have been running this tweak for a few days now and love how facebook loads up like my contacts. I can say (and my wife will back me up, :laugh: my in-home beta tester :laugh, that there is little to no redraw when switching from dialer (and i use exDialer), to contacts, to msging (goSMS).

Did you install this on top of using the V6 Supercharger? Right now I have done ICS Tweaks and the V6 Supercharger. With the extended battery, I am getting ridiculously long usage and my phone is quite snappy for the most part. I guess I can just backup and try it and if it causes any issues just restore my backup.

Right now I'm using a few tweaks from pmr, and v6, and max-multitasking.
I started out with just the multitasking, then added v6, then played around with some tweaks from pmr.

It would be nice if we could get a ROM update with some of these tweaks built right in. or some sort of software app like other phones have where we could select all the tweaks from a list and apply the ones we want real easy.

I'm working on that. Aroma baby!!!!!!!! The esteem crew over at AF have done that with all the bloat ware stock apps and I'm working on that concept with all the flashable tweaks and maybe another one with all the stock vz/lg bloatware. The only bad thing is aroma makes flashable zips very large.

downloading now...
if I want to get back to stock kernel,, can I just simply flash the ZV9 stock kernel??
or I have to wait for your uninstall zip?

Uninstall zip should be up tonight

OP updated.
Added uninstall zip.
Updated install zip to 'actually' wipe dalvik-cache. ( forgot to mount /data in the zip. )
All should be good now.
Enjoy.

Bro, this works in other Devices? (Moto g xt1033)
Thx

I use it as my daily rom and it is on my phone almost stable. No reboots No freezes.
And not everybody knows about it.

sorry but this has nothing to do in dev forum. the funniest thing is that almost all steps are only advices. you wrote things on what to do, but not how to do. you didn't develop any thing.
and your latest post before this is from 7 april 2012 with 0.02 posts per day
are you serious ?

I get a google search FC after doing all these..
any suggestions..

Re: [ROM] [MOD] [GUIDE] CM10.1 Official + MOD + How to install
If the rom is stable, it should work without doing all this crap. And all of this us just known stuff, or your recommendations. No development of your own. This doesn't belong here. Noobys noob how to is enough.

Nice joke. Because it is a joke, is it?

hmmm......i kinda disagree, it is 'almost' stable, but with every version of the nighlties, i experience unstablility issues...
i think it's because of my kernel settings or the number of apps i've installed....
but then again, i'm using IZS with 90+ apps and with ZGK and i'm not experiencing any issues....yet.
......if you ask me, i'll wait for a stable release, if ever it becomes fully stable....
Just sayin'

guys, first of all you need not to install this rom at all.
I dont say that I have develop anything so what is your problem?
Everyone know what the word nightly means so I dont need to tell you that you can brick your rom...
I wrote almost stable, because I run it for 1 week now without reboot and force closes.
You can of course install only the Cm10.1 build, but I provide in this guide how to get the most out of it.

Official 4.3 ram consumption

Since my update on official 4.3, I have a high consumption of ram ... after starting the system already uses 1GB ram and after a while the RAM is full, even if I stop all applications Recent ... am I the only one in this situation?
I'm on the official 4.3 UB with Xposed framework and gravity box.

Try this command on terminal emulator, then post the result here
Code:
# ps | grep system_server

use MA6 kernel, set CPU governor to smartassv2 with 600MHz as max cpu and 245MHz as Min CPU frequencies..
Enable Kernel samepage merging in Memory management..
Enable GPU rendering in Developer options..
Memory management is fine in kitkat, Os is not taking much of memory..Better go for greenify app, greenify google services and apps to get battery..
I never tried sd extension dude, so i am sorry i can't help you in that matter.. Hope someone will clear your doubt regarding this..
And help others with your feedback..

review
note: i'm not a rom-junky, this is my first cm after i've been playing with 9.2 and 10.1 while ago and to be honest - i prefer miui over cm because of its unique features and ultimate themeing
first impressions:
- stable and (surprisingly) ram friendly (one of the main reasons i wanted to test it, including greenifying which i miss very much in my favorite miui)
- everything ok with YourZgappsXS for 4.4
- everything working except for fm radio (tried spirit) << i guess it's a common cm11 bug?!
- i like the new camera very much, but like @naresh babu said: "it's not very colorful" (closer to b&w)
- installed crossbreeder (p_goodbye edition) just because i used to use it with other CMs and it there's nothing about performance scripts in MA6 kernel thread >> don't see any difference and i don't believe in virtual testing
- MA6 kernel @245-729 smartassh3 with sioplus (tought it would give me max performance) with ksm and zram (@69mb) <> would like to hear learn about other's experience with different settings (original and/or other kernel)
- at the moment running (cronmod) INT2EXT4+ without problems, but since my sd is lousy i believe it's producing additional lag; will try with my favorite: s2e
weird stuff and help needed:
1) tried to remove some bloaty and system apps that i don't use (whisperpush, android keyboard, terminal emulator, simtoolkit) with TiB and clean master; everything seemed to work ok, but they reappear instantly - even without reboot?!!?
2) attempted to change superuser with su (with an old flashable zip that worked with other CMs) without success <> superuser sucks, it's very slow compared to su and not updated
3) getting frequent "android.process.media has stopped" when boot and accessing sd, but it's probably because i f*****up something, or maybe int2ext4?!
will attempt to solve these issues messing around with the rom before installation, but it would be better to have the possibility to fix them afterwards
also, i will test more with xposed (mainly regular modules + greenify and xtheme)....
btw any cartoonish (BUUF like) theme? (complete, with icons, menus, statusbar, etc)

Firstly i want to thank you for providing review.. and

[DISCONTINUED][ROM][T715] Formula Performante [6/03/2019][CRH1]

Welcome to Formula Performante...
Hey there fellow Tab S2 user! So... your wondering what this ROM is huh? This ROM is the fruit of my labour, after many many hours of work, research etc. This ROM is genuinely the lightest stock based ROM, in all of the Tab S2 ROM era. The ROM weighs just 675 MB, its RAM usage only 1.0-1.1 GB and its fluidity and speed is unmatched, since any and all modifications have been directed towards only enhancing performance and battery life. So, what does this ROM pack? Here's a list:
Features:
1. Extraordinarily Light Operating System with a very deep debloat
2. Google Apps Removed while still maintaining SafetyNet
3. Latest @engine95 Kernel with Enforcing and far more superior RAM Management
4. Updated SoundAlive with slightly modified Volume Increases
5. Every App has been replaced by the lightest equivalent (For e.g, for the Music App, I checked RAM management of Google Play Music and Eleven Music (Cyangogenmod) and found that Eleven Music used 50 MB of RAM lesser than GPM, so I used that. This should give you an idea of how much research and time it took to find the lightest variant of most stock apps)
6. S8 Camera UI with FHD 60FPS,Tracking AF and Standard Improved Autofocus. Other than these improvements, the camera app was debloated as well, and any useless modes were terminated and rooted out.
7. Completely De-knoxed

Thanks. Just installed it.
First impressions:
Starting with "Music has stopped". Oops.
Upgrading Magisk Manager results in error, because Magisk version lower than v18.0 not supported. You should mention this. So no updated version of Magisk possible here (from 17.1 to 18.1)? Oops
its fast, really fast. Wow
more to follow, will just reinstall everything to get Magisk to work.

Oh yeah, thanks for reminder. OP updated

You should explain why it isn't possible to update to the newest version of Magisk. It isn't so nice installing a new ROM with an old version of root and no chance to fix this.
Update:
Removed the ROM. Titanium Backup crashes immediately. So unusable for me.

He explained why...upgraded versions of magisk are not compatible with the custom kernel he used inside the rom. Possibly if the kernel gets some updates we'll get magisk updated support too.
Btw idk why Titanium crashes...will test tonight if happens with me too. Dumb tought: maybe it uses some gapp related services to work and then it crashes because thei're missing? That sound stupid i know...
For the Dev:
It's possible to install gapps (bare minimum as play store and play services) or MicroGapps in this rom? Just in case i wont rely on Fdroid or other thirdy part stores. Thank you

Ok so Titanium backup, is related with the kernel being enforcing. Titanium require permissive which I didn't release due to the many security holes it usually poses. Oh and about Gapps, don't flash.

Updated Magisk 17.3 and up, (18.0, 18.1) compatible kernel is here https://forum.xda-developers.com/showpost.php?p=79164496&postcount=42
Enjoy

Can't enable any Accessibility Services telling that the text to speech language is not supported and when i tries to force itself to change it to english it restarts.

Thanks

core issue imo is that the calling app dialer does not show up during a call-no call ui (call received but no way to accept it) if there was a way to go back to stock dialer and messages this ROM would have been perfect. too bad all in the past now.

For me, after some finetuning, this is the best, fastest and most stable and compatible custom ROM ever for the SM-T715. Thank you Skulldron!
My finetuning after flashing the ROM (TWRP is clearly a requirement):
1) flash new Kernel v1.4
2) flash Magisk v.21.4 (the last one before Magisk (with v.22.0) became an "App", bundeled with the Magisk Manager )
3) install MagiskManager-v8.0.7.apk (The last separate Version of the Magisk Manager before it became a bundle with Magisk)
4) install newest Open Gapps for Arm 7.0 ("Micro" bundle in my case, because I need Exchange support that seems only to come with GMail) choose the one for your needs if you need: open gapps 7.0 arm
5) install Magisk Module "Google Dialer Framework" via Magisk Manager
6) install Google Phone (The offical Google dialer app shows a "device not supported" message but works fine with the Performante Rom. If you don´t like the error message, try another dialer app)
7) install Google contacts (The offical Google contacts app that works fine with the Performante Rom)
That´s the good and stable working basis installation for me. I do not need any google account and use sources like F-Droid, uptodown or the A**zon appstore for some charged applications i need (like Business Calendar, Mobile Doc Scanner...)

Based on you description I reinstalled this one because all other custom roms result in reboots, looping etc.
- Installed stock Gapps (Micro wasn't even available for 7.0)
- the newest kernel 1.6.1
- can use phone and contacts without warnings and problems
- upgraded to lastest magisk version, get warning about system app etc (seems a known problem right now, so I'll wait). But root works
- Netflix, Prime working, Disney with error 39
- fast!
-------------------------
Very good until now. Have to wait a few days and see if the reboots/boot loops etc are gone.
-------------------------
I'll use it only inhouse (since yesterday we have a Galaxy Tab S7+ as primary tablet, but: I can't use it because my daughert occupies it constantly!). Maybe this old and slim rom will give the S2 a new life.
@photona: Thanks for your post. Without it I never would have tried this one again. Sadly Skulldron was last online some months ago...
@engine95: Thanks for updating the kernel!

Thank you for the tips, after installing opengapps, system webview will be missing, so I have to push a webview (v70.0.3538.80) into /system/app and install it again in the system. Didn't you encounter this issue?

I don't use webview, so: no.

cant believe i haven't tried this before. made this ancient tablet very useable. I wish they still made tablets this size, this thin and light with such good screens. its perfect if you want to read the news or surf social media, want something bigger than your phone but not a monster tablet like most these days

Been using for a couple of days now and it is the best rom by far for everyhting, tried lineage android 10 and 11, both of them make the tab run very hot in games and after a few mins the graphics glitch so bad it is unplayable.
This rom however, the games run great and the tab only gets warm. Also battery usage is superior to all other roms ive tried.
Thank you for your hard work.
Glad to see the link still works, shame this was the last rom ive tried, the last happens to be the best
