sEFix Description: 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:


android.permission.INTERNET &
android.permission.ACCESS_NETWORK_STATE -> for ad banner.

android.permission.RECEIVE_BOOT_COMPLETED -> for applying the fix on boot.
