Hi.

I will posting the last version of monitor. Now its shows the "entropy_avail" after READ event.

My device (N8000) not run any scripts, Seeder or other tricks.

Only stock and rooted device.

By the way, log shows activity in "random" only when i enable WIFI. Same result in GNexus.

And "elitevet", dnt flood thread with wrong informations... and please, respect my personal work.

I believe this forum exists to exchange informations and experiences, not for personal promotions or earn money.

the outp.n8000.1.zip contain log for execution with N8000, enabling wifi, utorrent and playing The Sims Freeplay.

if you run the monRand you see:

20130106 20:50:07 random [ open] [1 0 0 0 (1)]
20130106 20:50:07 urandom [ open] [12 11 11 0 (1)]
20130106 20:50:07 urandom [ read] [12 11 12 0 (1)] 132

20130106 20:50:07 random [ read] [1 0 1 0 (1)] 5
20130106 20:50:07 random [ close] [1 1 1 0 (0)]

in format:

Date time access (urandom or random) operation (open, read, close) and an summary with opens, closes, reads, writes and pending instances.

if read operation, last info is "entropy_avail".

do the testing yourself and check the results.

no root need. simple put "monRand" into /data/local/tmp, change permission to execute. i use Windows box and run with console.

adb shell /data/local/tmp/monRand -lstdout -s/data/local/tmp/shutdown >outp.n8000.log

before, i use my device and see results.

and, definitively, these is no BUG in Android. is a placebo. if you run a infinite loop in terminal you get the same effect, no lag... and battery drain faster!

for the comparison i run the monitor in my Linux box and acquired same behavior.

Thanks for this! It's made my miserable Droid 3 (work phone) tolerable! I would hardly use it because of all the ridiculous lag (I thought it was just from lack of ram... old phones with little ram..) It'll never get to Jellybean (can't really install a custom ROM on a workphone) but this at least makes it so I don't just want to throw it against a wall :)

No wake locks at all (as expected).

So whether you think its placebo or not, having it running shouldn't have any hit on battery life.

with seeder 1.1 I have constantly a value of ~ 3900 when I type "cat /proc/sys/kernel/random/entropy_avail" , if I want to test this command do I need to uninstall it before ?
[Android Software/Hacking General [Developers Only]] pepoluan:
The sysctl incantation is meant to be replacement of Seeder.

There should be no problem using both, but unnecessary.

That said, rngd (the binary of Seeder) seems to have more effects than just entropy pool filling. But if sysctl is enough for you, by all means use it.

Sent from Note 2 running Jedi X
[Android Software/Hacking General [Developers Only]] dwang:
I don't see how the sysctl version is equivalent to the seeder apk.

The whole point of the seeder app is to prevent the kernel from generating random numbers because it blocks.

Changing the read wakeup threshold still has the kernel generating random numbers so it doesn't solve the problem that the apk is suppose to fix.
[Android Software/Hacking General [Developers Only]] debork:
Seeder app keeps kernel from mixing hardware input (or only 1/4096 inputs) because it keeps bucket above trickle_thresh.

Higher read_wakeup_threshold and write_wakeup_threshold encourages normal entropy generation stay at higher quantity...if it stays above trickle_thresh, then same effect.

[Android Software/Hacking General [Developers Only]] STELIOSFAN:
Well, I've been using seeder in 3 rooted phones. ZTE BLADE (older apk version) , SE Neo V (older apk version) , Galaxy S3 (older apk version and then updated to newest V6 zip version and flashed via CWM after I fulled wipe in order to flash new ROM & kernel) for weeks now

1. NO BATTERY drain at all !!! Maybe there is some, but I really can't tell any difference on the battery life. Same as before on all 3 phones.

2. Blade feels the same with or without seeder. Neo V feels faster and Galaxy S3 is a charm. The biggest difference is on Galaxy S3. I don't do benchmarks and there is no mention that the phone will run faster, so I wasn't expecting a great performance bootst. The dev clearly mentions that the phone will be less laggy. Well, that's the case and I can confirm it. Especially in Galaxy S3.

Don't believe me? Don't use it. But I would like to personally thank the dev for this great app. No problems, no battery drain and phone feels snappier. Well, why not use it ;)

I'm using a chinese phone running on MTK6577 dual core 1.2GHZ processor and i've installed the Seeder 1.1 APK. So far no difference at all. Will keep using for a few days to see it it has any effects but I'm guessing this script works differently for different processors which is why some phone reported great differences, some little differences and some no difference like mine.

Can somebody confirm this for me whether or not different processors affects the Seeder's effectiveness?

I dont think speed is the real issue. I think smoother user interface fludity is the real issue. If people perceive a smoother flow of operation and transitions on their device screen then thats all good.

Most of use with quad core and 2 gig ram devices would probably never notice these things... but we cannot take this view for granted.

People perceive thibgs differently for a number of biological and neurological reasons

I may see red intensely while you may not.

I may see small movements more clearly while you may not.

In the past these subtle difference in people contributed to who was a better hunter in the tribe or who was a better painter.

[Android Software/Hacking General [Developers Only]] jova33:
I'm not denying that it makes a difference. If I could find my old phone, which I nicknamed the lag monster(would lag so hard I couldn't answer an incoming call, thus defeating the purpose of the phone), I'd love to see the improvement.

And I agree with you that any improvement in speed is nice. If it did absolutely nothing, devs wouldn't bother implementing their fixes.

I would also like to see how this would fare on devices that have locked bootloaders where you can't modify the kernel.
[Android Software/Hacking General [Developers Only]] Fallingwater:
Found this via hackaday, installed the seeder on my cheapo generic tablet (CPU = Allwinner A13) and unless I'm fooling myself (but I sorta doubt it) it's made a world of difference. I can now actually use it without having to kill apps all the time and reboot it often to get it to speed up. Thumbs up, way up!

I have yet to be convinced.

I have run the apk on my DInc2 (active), OG Droid (wifi), and G1 (wifi).

The G1 normally can go several days on a charge (being used only minutes per day), but with seeder active it will eat up the battery overnight.

I can't report on the other phones at the moment.

It's not worth adding to the cruft in this overwhelmed thread with another post, but I wanted to say that I loaded the apk onto my wife's range and since then the bacon has been tastier than before. I'll try it out on the washing machine and see if it uses less detergent. :D

I installed your app on my nsz-gs7 Sony Google TV it it worked. Greatly improved the lag when switching between apps thanks a million
[Android Software/Hacking General [Developers Only]] rmagruder:
I did something interesting yesterday which no one has really talked about. I have a Nexus 7 and my wife has a Transformer Infinity. Same processor, after all.

We were trying to do audio recordings using the VoicePro app from the Play Store. When I first started using that app on my N7 I got occassional recording stutters and hiccups . I'd press the record button and there might be a bit of a delay before recording started, and while recording, the device might lag, creating a chopped up recording in some spots. I haven't had the problem at all since doing the stuff in this thread (updating read_wakeup_threshold as well as running Seeder).

On the other hand, my wife's TF700 running stock unrooted ASUS Jelly bean SUCKED. I mean, we couldn't succeed at even a simple 5 second recording without lag screwing the recording. Meanwhile we did more than 20 recordings on the N7 flawlessly.

It made me wonder if that would be a useful test that would be a bit more objective than perceived smoothness. After all, if the kernel blocks during a recording, there is a permanent record of it, as you hear it every time it plays back.

thoughts?

[Android Software/Hacking General [Developers Only]] rmagruder:
I know that. Maybe I wasn't clear in my communication. I'm debating whether or not to go ahead and unlock/root the TF700 so I can try this tweak out.

BUT, before I do that, I was hoping someone reading this thread might actually try testing a laggy microphone recording app WITHOUT and then WITH this seeder/entropy fix to see whether it actually fixes audio recording lag.

It would certainly help me with the current conundrum I'm in, if I knew the answer, and as a side effect to the community, might provide a more emperical means of testing the effects of this fix in a less subjective way.

There's one video showing that occasionally lack of entropy will cause an app to crash when starting but not of the "performance benefits" being claimed.

I even offered to do a video test on a Galaxy Nexus and Galaxy Note I717 if someone who noticed consistent differences would simply list the app and the steps that would have an UI lag without Seeder but didn't get anything.
