Lag reduction for ROOT users!
On some (older) versions of Android, the JVM (and other components) often read random data from the blocking /dev/random, which has a low entropy by default, causing that some processes block themselves waiting for new data generation with a greater entropy.

This app modifies the system's "wakeup threshold" to update /dev/random values more often when the entropy is too low.

Details for nerds available here: http://linux.die.net/man/4/random

I thought straight away someone saying entropy,they must be good at what they are making an app for,I must say that it's exactly what it states it works miles beyond what I ever thought it would I used it in conjunction with a cpu control already loaded for octa core devices,and na considering it behaved like a single core prior to all tools it now slams through it all like a bullet.It's an honest and extremely good app the likes of which I am yet to see rivalled,it's like it's done the math and other tools have not.

I upgraded my not well known Asus tablet (z380kl) to cyanogenmod nougat and it was still lagging in some areas. Despite the description saying its for older devices, I installed this app and the tablet is now smooth AF. I recommend this to anyone with root.

I figured that people were exaggerating about the diff this app made, because I've used other Entropy apps (they did make some diff), but they weren't! I immediately noticed the diff with this one and it has made my device buttery smooth! I don't know what this guy is doing diff, but whatever it is, it's working! If anyone cares to know, I currently have mine set at "High".

This app is amazing! I've never encountered any app that gave me performance like this. I don't even understand. So much better than seeder. This app is super amazing and I recommend it to everyone who's looking for good performance by tweaking entropy pool. You won't be disappointed . Thanks a lot developer for making such an amazing app. I wish I knew about it before.

I can't get root on my device it never works for me no matter what I do I can't believe you need root to use this app and get rid of lags

Running this on my ancient HTC Evo4g on a modded gingerbread ROM. It makes the phone feel brand new. I can't believe the difference.

I am thoroughly impressed by this application. Rooted my Android, /proc/sys/kernel/random/entropy_avail showed low values and my phone was running slowly. After using this app to produce more entropy, my phone is much more responsive. Thank you!

Freezed my GT-S7500 for some minutes after installation, then everything back to normal

Used on old jelly bean OS tablet that lagged all the time. Tried this after constant freezing and it appeared to make it worser & worser so I'm uninstalling & just play with the systems heap size, hoping it helps, already rooted tablet

Not sure if it is affective cuz mine is not very affective my tablet still lags...

Dad. B. Sep 11, 2018     

Not so sure if I'm able to enable ultra because of root but I just don't wanna add roots man!

Bro. M. May 3, 2018

I'm on a tmobile LG g4 (h811) with 2 of my 6 CPUs disabled. On resurection remix official on marshmallow It worked. On oreo via lineage os (a custom build for the g4) it doesn't work. It doesn't detect my entropy at all. And yes my phone is rooted.

Ros. A. L. Feb 17, 2017
