Frequently asked questions:

Q: Can I use Fly-On MOD™ with my device?
A:Fly-On works on all Android devices(Samsung Galaxy,Sony Xperia,HTC,Google,LG and all other OEMs) with Root,busyBox and init.d support.

Q: Should I patch my services.jar?
A:If you are using Fly-On's RAM config in top of Android 2.3 you'll not need to patch them,but since Android 4.0 OOM values are hardcoded into the services.jar so you'll need to patch them to have 100% RAM management.

Q: How to patch services.jar
A:you can either patch them using supercharger V6 script before installing Fly-On Mod or use magic patching tool by zeppelinrox(thanks to him),Visit his thread.

Q: I'm coming from an old version should I uninstall my version before installing new one?
A:No,Just new version over old one, the installation package will do everything.

Q: I feel very comfortable with my current old version,why should I update to never version?
A:Even If you feel very comfortable with your old version you should update to get latest improvements and bugfixes.

Q: What is EXT4 tweak?
A:It's a tweak that disables EXT4 journalism which increases I/O speed.

Q: Can I use EXT4 tweak?
A:In order to use this one you'll need your phone's file system to be on EXT4.

Q: Can I use INT2EXT+ with Fly-On Mod?
A:Yes It's totally compatible.

Q: Can I use Fly-On MOD™ with any other MOD that uses init.d scripts,binaries and Tweaks?
A:No,you can't as they will conflict ,so choose one of the them.

Q: And when I install a newer Fly-On version should I re-install my RAM Configs/EXT4 tweak?
A:No need.

Q: What is the best kernel to use with Fly-On?
A:No one is the best,Use any custom kernel with init.d support.

Q: What is entropy generator engine?
A:It an engine used to reduce lags by keeping a section of the Android file system (/dev/random) full of random bits so that the system does not have to wait for the file system to generate them.

Q: So for better performance/battery Entropy generator must be on or off?
A:No,It just off by default to let users have their own choices.

Q: Can I use Supercharger V6 with Fly-On Mod?
A:Yes,but If you are using Fly-On RAM manager delete It first.(Keep Fly-On main package installed).

Q: How can I uninstall Fly-On?
A:Use Fly-On uninstaller It's compatible with Version 4.0 only.

Q: But If I have an older version what to do to uninstall Fly-On?
A:Update your version to V4.0 A6 first then Flash the uninstaller.

Q: Do I need to mount /system or /data before flashing?
A:No need to do that as the installation package does everything.

Note also:

- Don't use any Task Killer with this Mod!
- Don't use Fly-On Mod with any other tweaking script as they will conflict!
- If you want to use Fly-On Mod in your ROM or your Mod ask for permissions first and give me credits!
- If you have any question ask me in the thread instead of PMs or I will not reply!
- Read well the thread before posting any newbie questions and do not ask for an already answered question!

The main goal of using scripts and tweaks:

Scripts and tweaks are used :
-Improve Performance and GUI Smoothness.
-Improve Battery Life.
-Tweak and Optimize the Android engine!


Useful Info About Tweaks:

-LMK:
The Low Memory Killer is a constant debate between more free RAM and more multitasking capabilities as free RAM (more than 60MB free) is actually wasted RAM.
The Low Memory Killer is actually a feature in the Android OS used to improve memory management.

This is an important feature due to the perennial problem of having low free memory causing lagginess and slowness in launching apps. When you have free memory lingering around the number of 40MB or less, the Android OS just lags like hell.

What this would mean is, you would want to tweak the LMK to not have the situation of it having less than 40MB (or even close to that).
The modern Linux machine in the Android ecosystem relies on a mechanism called Low Memory Killer (LMK) to consistently free up RAM. This is due to Android's internal mechanism of caching apps (and never fully exiting them) when you press the back button. This is to enable faster app switching and provide a seamless experience for apps usage model. Android also, by itself will also constantly look for often used apps to cache them for faster app opening. This will happen even before your system fully boots.

Now, when you mention LMK, the most obvious thoughts that come up are minfrees and Out Of Memory (OOM) groupings. Yes, those two are integral parts when it comes to LMK. The issue here is that no one actually mentioned that there are two LMK systems in Android, that being:
- Linux LMK
- Android Dalvik VM LMK

-Journaling/Barriers:
-This has been a touchy subject here in XDA for most people who debate about it. Most recently,Some Scripts included a way to disable journalism on these partitions:

/system (System is read only, it's safe to remove journalism. However, you will not see speed increase by removing it as you're not writing onto /system 99.99% of the time unless you're using Titanium backup to remove system apps or copying init.d scripts to it)
/cache (Cache can be rebuilt on the fly. Data corruption on it is not game breaking)
/data (All of your data on your phone is here. Removing journalism can risk data corruption. Read more below)

On whether we need journalism or not, I will pose this situation:

Journalism is required to maintain data consistency in events that could lead to data corruption. Data could get corrupted in a number of situations:
- Misbehaving app that constantly writes without syncing/committing data to the disk
- Power loss due to forced reboots or bootloops when data is partially written/committed into disk

-Memory leaks:
If you found out that your Android is laggy after sometime and a reboot will make it faster, then you're experiencing memory leaks. "free" is a command to show your currently free memory. It will not necessarily be the same value as your phone's free memory.

-Busybox:
Busybox is required to perform all of your superuser activities in your android phone. There are some problems associated with this when ROM developers decide to use a certain version of Busybox that are incompatible with the binaries that we use in our phones.

-MinFree:
Minfree is part of the Kernel used to multitasking and It differs from a Phone to another because of the RAM available in users space.

-Network Tweaks:
There are some Tweaks that are used to increase the speed of your Network browsing,downloading and uploading

-Build.Prop Tweaks:
Those Tweaks can generally be found in Build.prop /system and they are used to optimize overall system speed and battery

-SD Card Speed Fix:
This is a Tweaks that Has the goal of increasing the read-ahead speed of your SD Card,and that by improving your SD R/W speed.

-Smoothness Tweaks:
Well with the Linux Kernel there is a possibility to add some Tweaks to optimize the GUI Smoothness.

-Entropy generator engine:
This engine can reduce lag by keeping a section of the Android file system (/dev/random) full of random bits so that the system does not have to wait for the file system to generate them.

-Zipalign:
Zipalign is a tweak used to optimize Android application (.apk) files. The purpose is to ensure that all uncompressed data starts with a particular alignment relative to the start of the file. Specifically, it causes all uncompressed data within the .apk, such as images or raw files, to be aligned on 4-byte boundaries. This allows all portions to be accessed directly with mmap() even if they contain binary data with alignment restrictions. The benefit is a reduction in the amount of RAM consumed when running the application.
