Hmm, I've not played it a lot, but I've never seen any lag. Is there?

Edit: Another thing.. If anyone could give me a pointer as to how to set up per app governor in tasked I'd much appreciate it. I'll figure it out myself I just can't find the variable for governor. (Update : FOUND IT :) )

By the way, anyone who hasn't had a look at tasker should do, it looks like a really amazing app. You can make it do things like automatically putting your phone on silent when you get to work by GPS. That's a very simple example. Unbelievably cool what can be done with it. The only thing is it really helps if you've done some computer programming to be able to use it.

But that also makes it interesting to me. I like a challenge.
[Nexus 7 Themes and Apps] bradman117:
well i was getting some. i didnt have any oc or anything on. and i did see some lagg maybe it was me?:confused:

can some one check there entropy_avail file?

proc/sys/kernel/random/

i dont have my phone or nexus 7 for a couple days. but did the file only say 172?? I thought it had more in it. someone please check on that? :) thanks!
[Nexus 7 Themes and Apps] Richieboy67:
I have no issues with lag on any of these games. Not sure any app is needed except maybe for games that are not set up for the nex 7..
[Nexus 7 Themes and Apps] Adinaky:
I can't download all the files. The 91RNGD link is the same as the entropy_avail link. Can you do something?

One more question: First I put these files in their places, fix permissions and then I flash the archive?
[Nexus 7 Themes and Apps] Larry94:
Same boat. Flashing or APK doesn't work, so I'm not sure what to do.

EDIT: Mine says 4026, does that mean it worked?
[Nexus 7 Themes and Apps] bradman117:
in 4000s sound about right

Amazing on Nexus 7

The is the single most amazing thing i have ever known, NFS most wanted, Nova 3 even bloody gamelofts spideman was utterly

Lag free and i don't even have my nexus 7 over clocked at all while running this, usually have to without it to get smooth gameplay and ui

Thank you
[Nexus 7 Themes and Apps] lordvincent 90:
Sure.

Download entro-tweak.zip

Extract the contents.

Using a root explorer, take the 'entro' file and place it in /system/xbin/ and set permissions to rwx,r-x,r-x

Then take the '20Entropy' file and place it in system/etc/init.d and set the permissions to rwx,r-x,r-x.(I created folders inside the zip to mimic their location)

Reboot.

Open terminal and type

entro

to monitor it.

It will run the equivalent of "watch -n 1 cat /proc/sys/kernel/random/entropy_avail"

When I get home later tonight I can just make it flashable if anyone is interested (or these instructions arent clear enough)

installed the APK on my Droid RAZR w/ D-WiZ 4.1.2 and run that cat command and i'm getting 1200~1350ish every second. sounds about right?

need to get home to try it on my Nexus7. so far i can't feel anything different on my RAZR.
[Nexus 7 Themes and Apps] buffjam9011:
Normally I flash whenever I can, but this was simple and it worked for me. entrop_avail is in 3600s now
[Nexus 7 Themes and Apps] ace-user:
i turn it on but when i exit the app and enter it again, it shows "off"...so is it working or not? how do i check?
[Nexus 7 Themes and Apps] DarknessWarrior:
ok so i tried the "entro-tweak" and it now shows 4096 on terminal. so it seems to be working.
[Nexus 7 Themes and Apps] doublin:
I have the same question.
[Nexus 7 Themes and Apps] DarknessWarrior:
i just updated my ROM and redid the entro-tweak and now it says "entropy_avail went up 40-60" and once it reaches like 1k it says "entropy_avail went down 1000" and just starts all over again.
[Nexus 7 Themes and Apps] lordvincent 90:
Are you sure the permissions are correct?

I know with mine, it doesn't climb very fast, but mine went up to almost 4000 and its been staying there.
[Nexus 7 Themes and Apps] DarknessWarrior:
755 on both files, right?

edit: also looks like task killers make the entro go down, maybe because of the re-opening apps use all the entro
[Nexus 7 Themes and Apps] lordvincent 90:
755 is correct. And I'm not sure about the task killers, I don't use them.
[Nexus 7 Themes and Apps] DarknessWarrior:
i'll change it to 775 then.

but it seems to be working better now, it now goes up like 100+/s instead of the 40-50/s
[Nexus 7 Themes and Apps] lordvincent 90:
*Facepalm* that was supposed to say 755....

I was affirming that you had it correct
[Nexus 7 Themes and Apps] iofractal:
So which should we be doing here the directions for seeder or using entro-tweak.zip????
[Nexus 7 Themes and Apps] DarknessWarrior:
oh lol, yeah i have 755.

it is working i think. It is a bit slow getting to the 4k but it eventually gets there

edit: it seems to be stopping at around 3590 (3586-3597)
[Nexus 7 Themes and Apps] lordvincent 90:
Sorry... didn't mean to thread jack...:o

But the method in the op actively runs every second in the background, quickly refilling the pool, while the entro-tweak builds it up a little slower, but doesn't require a process to be running to do so.
[Nexus 7 Themes and Apps] sefirosu0522:
I flashed the CWM file with TWRP. I then checked with root explorer and none of these files are there. What can I do?
[Nexus 7 Themes and Apps] iofractal:
manually place the files and change permissions then flash the zip
[Nexus 7 Themes and Apps] ÜBER™:
You didn't type that as root. Type su then hit enter... then do the command.

Actually I just did it... Didn't work. Just do cat... Take out the watch -n 1. It should spit out a number. On my N7 its 4096.

Also i cannot see any benefit, NFS i running ****ty as always.

When i type the Terminal command i only see a ongoing list, an echo of the command, but cannot see any real values , like the 3000/4000, no info at all ??

[Nexus 7 Themes and Apps] Atrix2destroyer:
I did this on my Nexus 7 using the entro tweak zip. It works because now my entro shows almost 4000 but it seems like my battery drain was majorly increased. I went from 63% to 56% within an hour. zero LAG in Batman the dark knight though. There used to be major LAG from that game, its almost transition-less now.

---------- Post added at 01:08 PM ---------- Previous post was at 01:05 PM ----------

try the entro tweak zip on page 4 i think. It double my entro values and you dont have to post anything at the kernel level so the kernel may have nothing to do with it.
[Nexus 7 Themes and Apps] R3dbeaver:
anybody else can comment on battery life yet?
[Nexus 7 Themes and Apps] darkuni:
I hope this doesn't turn out to be a fake, and I'm just susceptible to suggestion ... because this really appears to work. Tried on Nexus 10 and Galaxy Nexus (Vzn) and I see notable improvement.
[Nexus 7 Themes and Apps] Atrix2destroyer:
Just type entro, it will show the values like a ping would show up and automatically update. Mine went higher with every touch and swip i did and i ran itin the background during a game and it showed almost 4000
[Nexus 7 Themes and Apps] lordvincent 90:
Less than 10% in an hour, while playing a graphic intense game is a big increase in drain? Mine drains about 10% an hour while using it normally :D
[Nexus 7 Themes and Apps] Atrix2destroyer:
I wasnt playing a game, just normal use. Before i did the entro tweak i had 40% at the end of the day (around 7pm) and thats with playing with it all day (web browsing, using tablet talk, multiple social accounts synced, playing games) if it were only 10% an hour during gameplay that may be expected especially with the increased entro.
[Nexus 7 Themes and Apps] porkovich:
hm , you are right, if i type SU and leave the watch -n 1 i get the value - it's 4096 with my nexus. But strangely , NFS dont run any smoother ? and i read that there is a major improvement there .... maybe i can try the entro thing ....
[Nexus 7 Themes and Apps] stfudude:
Running this for a day now. I flashed Seeder V5 CWM zip from the original thread. I can safely say that I notice a minor improvement. Maybe it's just minor because my Nexus is still in need of more ram (I have many background services chewing ram all the time). I don't over clock my Nexus before and after trying the tweak. Battery level is definitely higher with this tweak, as I expected.
[Nexus 7 Themes and Apps] iifuzz:
I did this on my phone and everything seems to have more lag
[Nexus 7 Themes and Apps] ÜBER™:
Its not a miracle worker its not gunna fix a poorly coded game. The only time I get lag on MW is when it comes up to a road block.. Which also happens on my GS3 so I'm pretty sure that is by design.

Hi,

I installed files one by one on Nexus 7, after reboot I deleted because nothing improved but I am not able to delete this file:

entropy_avail from /proc/sys/kernel/random/

I tryed to delete from TWRP -> file manager .... but still no chance to delete this one.

any idea ?

thx
[Nexus 7 Themes and Apps] Zorua:
Can't seem to move entropy_avail to proc/sys/kernel/random. It says access denied. The other files copied fine though.

EDIT: oops, ninja'd by poster above.

N00b question - sorry

So I'm trying to cook this into my rom (I've been building AOKP nightly from source) - but my update.zip doesn't have a /proc folder to put the entropy_avail file into. So I've got the 91RNGD in my init.d with proper permissions (0755), and I've got the rngd file in /system/xbin with the correct permissions as well.

So - questions:

Is there a way to get entropy_avail into the proc folder at flash time?

Do I need to do that?

Is this the best way to implement this tweak into my rom?

This tweak can be done much easier without flashing any zips or running any daemons.

If you have init.d support, simply create a file (e.g. /etc/init.d/97urandom):

#!/system/xbin/sh (or wherever sh is on your device)
rm /dev/random
ln -s /dev/urandom /dev/random

and urandom gets symlinked to random at boot.

So, does the APK application only work if I'm running a kernel with init.d? Or does that not matter?
[Nexus 7 Themes and Apps] Flukester69:
This is one of the reasons it's not working for some. If you don't have init.d support you are screwed. Don't know for sure about flashing but the APK won't create any init.d folder. Rasbeanjelly doesn't have init.d, or the version I'm running doesn't. Many other ROM's don't either.

While this post is helpful, it's repeated and already available on the forums and was posted on Google+. Why we needed another one other than to leech more Thanks for someone elses work is beyond me.

A simple post that linked to the original article was all that was needed. To call people newbies and then neglect to give the information about init.d support makes me wonder who the newbie really is here.

While most of the discussion here about the technical aspects r mostly over my head I don't think the entropy avail file matters if the other files are deleted or if u uninstall the apk. I'm thinking if the init.d script is deleted or if the seeder app is deleted there is no way to start the process so the entropy avail file is kinda just dead weight and unused.
