Efficiency: LEDs emit more light per watt than incandescent light bulbs.[99] Their efficiency is not affected by shape and size, unlike fluorescent light bulbs or tubes.

Color: LEDs can emit light of an intended color without using any color filters as traditional lighting methods need. This is more efficient and can lower initial costs.

Size: LEDs can be very small (smaller than 2 mm2[100]) and are easily attached to printed circuit boards.

On/Off time: LEDs light up very quickly. A typical red indicator LED will achieve full brightness in under a microsecond.[101] LEDs used in communications devices can have even faster response times.

Cycling: LEDs are ideal for uses subject to frequent on-off cycling, unlike fluorescent lamps that fail faster when cycled often, or HID lamps that require a long time before restarting.

Dimming: LEDs can very easily be dimmed either by pulse-width modulation or lowering the forward current.[102]

Cool light: In contrast to most light sources, LEDs radiate very little heat in the form of IR that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED.

Slow failure: LEDs mostly fail by dimming over time, rather than the abrupt failure of incandescent bulbs.[103]

Lifetime: LEDs can have a relatively long useful life. One report estimates 35,000 to 50,000 hours of useful life, though time to complete failure may be longer.[104] Fluorescent tubes typically are rated at about 10,000 to 15,000 hours, depending partly on the conditions of use, and incandescent light bulbs at 1,000 to 2,000 hours. Several DOE demonstrations have shown that reduced maintenance costs from this extended lifetime, rather than energy savings, is the primary factor in determining the payback period for an LED product.[105]

Shock resistance: LEDs, being solid-state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs, which are fragile.

Focus: The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner. For larger LED packages total internal reflection (TIR) lenses are often used to the same effect. However, when large quantities of light is needed many light sources are usually deployed, which are difficult to focus or collimate towards the same target.

While interesting, I don't think it is applicable, those are all talking lighting, not displays.

...wait a tic, are you just being a smartass... :confused: :silly:

There aren't LED screens, it is a marketing gimmick.
[Nexus 4 General] apzalo:
I wouldn't want a LED screen on a phone. You have to hold that against your face all the time, you might get LED poisoning.

[Android Software/Hacking General [Developers Only]] soadzoor:
Hi,

I would try this, cause I experienced these lags, and they're really annoying, but I'd really need a simple instruction for what to do. You wrote how you managed to discover what to do and stuff, but I'm lost between the lines. Since I'm kind of a newbie, I'm kindly asking you to write some kind of instruction manual step by step, and forgive my ignorance :)
[Android Software/Hacking General [Developers Only]] lambgx02:
Not yet. If a few people try it and report positive results, I'll make a flashable image. Stay tuned. :)

I updated the first post with instructions. Please be careful, though! Let me know if you need more detail.
[Android Software/Hacking General [Developers Only]] soadzoor:
I got troubles. Using Terminal Emulator I got an error message when I type the 3rd line ("cp /mnt/sdcard/rngd /system/xbin"), it says: "sh: cp: not found"
[Android Software/Hacking General [Developers Only]] lambgx02:
Where did you transfer rngd to on your phone? Have to make sure the source path matches.
[Android Software/Hacking General [Developers Only]] soadzoor:
It does match, that's why I'm confused.. :\ which terminal do you use?
[Android Software/Hacking General [Developers Only]] Zero Computing:
Will test this later, for sure! If all goes well, may I request permissions to include this with the MIUI build I will be learning to make and attempting to produce?

edit: My phone wasnt particularly laggy before except when playing games, but there is a noticeable difference after executing this binary. Noticed a few small hangs but unsure if it is related to this binary.
[Android Software/Hacking General [Developers Only]] thegreatergood:
I've tested it ... integrated it into my rom and installed ... there was no lag even right after it first boot ... its incredibly smooth ... though I too noticed small hangs ... though I attributed this to the device getting ahead of itself ....
[Android Software/Hacking General [Developers Only]] Zero Computing:
Yeah it kind of seems like its fine after settling a bit. Can't wait to see it in 0.7 thegreatergood.
[Android Software/Hacking General [Developers Only]] lambgx02:
Ok, everyone. I built a very simple Android app that bundles the rngd binary and starts/stops it. Details in first post.

[Android Software/Hacking General [Developers Only]] lambgx02:

[Android Software/Hacking General [Developers Only]] suku_patel_22:
Came across this today. Looks really promising.

Interesting thing is we had an issue in office where Oracle database connections were getting hung due to same reason, waiting on /dev/random as entropy pool wouldn't get filled up in a VM in a data center. Entropy gets generated from noise which is hard to find in a data center. We had to use a similar solution.

What we had done is link /dev/urandom to /dev/random.

[Android Software/Hacking General [Developers Only]] irawanjohan:
Install seeder v5 via recovery.
[Android Software/Hacking General [Developers Only]] cn.fyodor:
Yeah, another random passer-by. :P

Not tested your flashable zip, but why not use a proper name for a script in /etc/init.d, like 20seeder? And the mount command at the first line seems unnecessary because /data partition has been already mounted with rw option. Correct me if I missed any hints. :)
[Android Software/Hacking General [Developers Only]] Ryuinferno:
No, without mounting rngd won't be able to write anything in it...and the name does not matter, most init.d in android uses run-parts, which excecutes ALL scripts in a directory regardless of their name...:)
[Android Software/Hacking General [Developers Only]] karun11:
Not able to install v4 or v5 via cwm :( can anyone tell me how to install manually?
[Android Software/Hacking General [Developers Only]] Ryuinferno:
What status error are you getting in CWM? Tried replacing the update binary?:)
[Android Software/Hacking General [Developers Only]] cn.fyodor:
You sure the mount command made any sense? It sounds unreasonable. And yeah, the name thing is just a suggestion. But by convention, the number does make sense for run-parts.
[Android Software/Hacking General [Developers Only]] Ryuinferno:
Yes...rngd needs permissions to write in data...a file name rngd.pid will be produced...if the line is not there, rngd can't write that file...experimented on it...and the name...hmmm...so far to me, it only affects the order of when the script is excecuted...but doesn't matter for rngd...it can even be executed post-boot...;)
[Android Software/Hacking General [Developers Only]] sonnhy:
I'm curious, maybe is a better solution than this script... Can you make a script that work the same way you fix the problem in oracle database connections, but for android?

Hey everyone,

1.2.7 released. Reintroduces rngd suspend-on-sleep with a much more efficient method.

Can anyone who is having trouble with autostart try this build, and run:

logcat | grep SEEDER

.. and paste the results?
[Android Software/Hacking General [Developers Only]] lambgx02:
Quite a few people have been reporting this, but I'm not sure why it's happening yet. If you have a second, can you install 1.2.7, reboot, and send the results of:

logcat | grep SEEDER
[Android Software/Hacking General [Developers Only]] androidwkim:
Fantastic!

I'm using this on a P505R and an Xperia Ray, and while the differences seem negligible on the Ray I can SEE the difference quite clearly on the P505R. Animations and transitions seem much smoother, more than can be explained by a placebo effect. However, the Seeder seems to have troubles when waking up the phone; it seems slow and takes a while to catch up. Perhaps because of the new sleep function in 1.2.7.

Anyways, great app. It was fun to watch it go from a few pages to 200 over the weeks and months.

TF101 loves Seeder

On my Transformer TF101 running stock (rooted) ICS .27 this thing is a game changer. Wonder whether most of the ICS stability problems were related to processor throttling?
[Android Software/Hacking General [Developers Only]] jr_718:
Problem seem to be fixed on 1.2.7.. But there's a huge delay after you reboot for the apk to open.. It might have something to do with superuser...

That was definitely it for me. I didn't get the SU grant pop-up. Eventually, I got a notification that seeder was stuck, so I killed it. Right after that, I got the SU stuff. Ran dandy after that little exchange.

FWIW, I installed 1.2.7 over 1.2.6 (after answering yes to "this will replace an existing application").

Thank You so much
[Android Software/Hacking General [Developers Only]] mdean1981:
Not sure if this has been mentioned but I notice when running this my Gtalk people appear offline after so time. Not just 1 or 2 but the whole list. The only way I have found to fix it is to reboot and then it happens again. It has done this on several ROM's now. Ive narrowed it down to the app because it only happens when this is running. Not sure if it is any help or been mentioned as I said. I just thought I should let the dev know.
[Android Software/Hacking General [Developers Only]] lambgx02:
Looks like it was getting killed on startup due to ANR. It calls rngd synchronously from the UI thread, but during bootup, superuser takes a while to respond. Android kills the process.

This latest build launches the process (at startup) asynchronously, but if you start Seeder before the startup completes, it'll show up as off. It will eventually start on its own.

I'm working on a proper threaded start/stop version, but in the meantime, if it's still not starting properly, try 1.2.8.

Sorry for all the updates! Still new to Android development. ;)
[Android Software/Hacking General [Developers Only]] jr_718:
Never apologize.. Never dude you are doing a great job thanks and you owe nobody an apology.. Lol knock of the apology:D
[Android Software/Hacking General [Developers Only]] fivefour:
The reason seeder works for some and not others boils down to the kernel being used.

The kernel on my Galaxy Nexus has a low entropy maximum by default (exception being imoseyon's latest as he integrated a higher default entropy), whereas my inexpensive M9000 tablet has a high entropy maximum by default and shows little to no improvement running seeder.

Mystery solved.

---------- Post added at 03:48 AM ---------- Previous post was at 03:45 AM ----------

The reason a high entropy value increases GUI performance is still debatable, I think it's due to blocking until entropy reaches the needed level.

This is amazing!

Installed Seeder on SGS3 with Revolution HD 14 and custom Perseus Kernel. Most of microlags are now totally and unmistakably gone! More than that: battery life has improved! Currently battery discharge at 0.7% per hour! Never seen it doing this well. 25 hours and phone battery charge is at 85% still! This is with data connection (EDGE) and various synchronizations. Wifi is off.

Thanks so much to author! Looking forward to donating for this amazing piece of work! :good: :good::good:

For example I had a microlag like 100-300 ms after turning phone on - the lock screen appears but dimmed and after the 100-200 ms it's finally updated (the clock) and usable. Or opening the GoSMS was lagging a little bit but now this lag is gone.

As I said the difference was clear and immediate. Long term benefits still are remain to be seen but what I see so far makes me really happy someone came up with this idea.
