Many Android tasks run slower than they should for one simple, yet not-so-obvious reason: they consume large amounts of random data from a limited source. Random data is used to generate session keys and unique identifiers, in SSL and wifi, while starting processes, and during inter-process communication.
This data (entropy) runs out frequently, and that causes processes reading from the blocking device (if any) to temporarily stop responding (lag). These processes cannot continue until the Linux kernel repopulates the entropy pool, which takes time. In addition, input events are pulled from the user interface (to refill the pool), which may also contribute to the problem.
Seeder is a service for root users. It assists the kernel in "topping off" the entropy pool by re-seeding it with data from the non-blocking (high performance) random device. Optionally, it can also help alleviate MMC I/O contention by extending the I/O queue, allowing the I/O scheduler to make better decisions, and combine more writes.
On some devices, applications load significantly faster (particularly large ones like Facebook, Chrome, and Youtube), and task switching becomes effortless. Fewer visual "hiccups" occur.
You MUST be running a rooted device to use this application! If you don't know what this means, Seeder will probably not work on your device!
** Note **
This app does not increase raw performance, but rather eliminates some types of annoying lag (ie. applications briefly freezing, jerky scrolling, delays returning to the home screen, etc). The effect seems to be more noticeable the longer the device has been running prior to activating the RNG service.
Google's efforts to optimize newer builds of Android have been substantial, and Seeder has less effect on Android 4.0+ (though many users still report improvement).
Bug reports are greatly appreciated. If you have any trouble with the application, please send an email before leaving a review. If during testing you find that Seeder does not noticeably reduce lag on your device, please email me for a refund!
This should be used alongside Seeder or in conjunction with your own performance testing.
There is currently some discussion the loading apps requires there to be random numbers available.
I got the idea after reading over this forum post:
I read up about random entropy seeding and I'm using the following values:
Do not randomize address spaces: Performance Gain at loss of security?
busybox sysctl -w kernel.randomize_va_space=0
Minimum number to write random numbers: (Goal is 4096, so this is 25%.) Observed value 133 at beginning.
sysctl -w kernel.random.write_wakeup_threshold=1024
sysctl -w kernel.random.write_wakeup_threshold=4096
Minimum number to read random numbers: // gives it more time to read?
sysctl -w kernel.random.read_wakeup_threshold=512
Also interesting: I took a bunch of screenshots for this app release, and the number dipped down quite a bit..
Optimus improves system performance and battery life by adjusting Android's internal memory settings.
How does it work?
Android automatically kills background processes when system memory falls below a certain threshold. Optimus changes those memory settings, causing Android to free up memory more aggresively, thereby increasing system performance and battery life.
Optimus has three different settings: Moderate, Balanced and Extreme.
Optimus is a SAFER alternative to traditional Task Killers, which are known to cause damage to the Android operating system.
NEW FEATURE - Optimus can now start a background service that seeds Android's entropy pool, significantly reducing lag. When Android's entropy pool becomes depleted, lag is experienced. This service keeps the entropy pool full, therefore reducing lag.

Talking to your friend and suddenly your phone shuts down and you don't know why because your battery was not dead????
Battery Calibration Pro is the best app to calibrate your battery. No root access required.
Battery Calibration Pro shows some battery stats such as temperature, charge level,etc.
1-Charge your phone until the battery is 100% full
3-Let the battery completely discharge
4-Charge the battery to 100%

This program requires root permission, busybox and Android 4.0.4 to work.
If you don' t know what root or what ClockworkMod Recovery is then you should not use this app.
Warning: This software is for MK802 using Android 4.0.4 Firmware. Be sure that you have the right model to be flashed. Different models can cause critical damage in phone system storage.
Just in case you're not familiar with what CWM is, and what it can offer us now and in the future. Follow this link: http://www.addictivetips.com/mobile/what-is-clockworkmod-recovery-and-how-to-use-it-on-android-complete-guide
MK802II owners should step back and think twice before trying to install CWM. There are various reports of success (with CWM) and disasters.
Make sure you have the most recent versions of BusyBox and SuperUser installed.
Make sure that both apps are up to their current releases and not using legacy (superuser) or 1.18 (busybox).
This software is designed for AllWinner MK802 Mini PC Stick
CWM does work perfectly.. and have been able to do nandroid backup with ease and restore my Mk802 to its previous state after doing a quick flash via LiveSuit. Goodbye Titanium.
Remember... if you do flash via LiveSuite (which we will all do over next week or so) you will need to re-install CWM.
CMW use: You can use a USB wireless mouse and keyboard plugged directly into the Mk802 (usb hub will not be recognised).
Navigation: Move mouse up and down or arrow keys on keyboard to highlight selection and left click mouse to select or left arrow on keyboard, right arrow to go back a menu...
Main issue most will face when it comes to the Upgraded firmware and CWM, will be that the CWM menu will now display incorrectly. This was caused by a change in the kernels cedar. You will be faced with a screen split into four views, and every other selection made will blank the screen.. generally just keep an eye on the top right screen.

All the credit goes to KEgg and Ricomagic forums for their excellent work.

*Currently supports Samsung Galaxy Note (tested on N7000), Galaxy S2*
*THIS IS TRIAL VERSION!!! FULL VERSION REQUIRES REGISTRATION AND IS PAID*
NorthAmerican/AT&T Note users - see comment regarding kernel below!!!!
TouchScreenTune application allows you to fine-tune settings of phone's touchscreen and calibrate Pen cursor position for every screen orientation (portrait/landscape...). (S-pen calibration obviously works only for Note)
It allows to dramatically improve responsiveness and sensitivity of touchscreen.
If you are using screen protector on your phone, the application will allow to raise screen sensitivity, so there will be no responsiveness impact from using screen protector.
This application allows you to calibrate amount of touch movement, when actual reporting of scrolling starts. That allows more smooth feeling of the interaction with the touch screen.
Without this application you cannot precisely draw or click small items with Pen because it reports position incorrectly - few millimeters away from the actual touch point. But this application allows you to precisely calibrate position of Pen touch on the screen. (Galaxy Note only)
Some common problems:
When first starting there should be popup from SuperUser application with request to get Root access. Some people say that sometimes it doesn't appear. In that case try starting the SU program first, and then this application.
This application supports standard Samsung firmwares - with custom kernels it may not work (however I have successfully tested it with some custom kernels)
Custom kernels: app requires kernel with KALLSYMS, so ask developer of your kernel to include this in his config when building kernel: CONFIG_KALLSYMS=y, CONFIG_KALLSYMS_ALL=y
Known issues: if when first starting application it seems to be not responding, and dialog asking to force close app comes - choose wait. This should happen only on first run.
