Free Seeder app lag reduction on all Android devices rooted required

  Hmm looks like it is targeting issues with certain versions of the OS and specific apps. I don't like the fix, there is a good reason random and urandom are different, if the app doesn't need random it can just use urandom.

  I didn't read all the comments, but this just doesn't sit well with me.

  Caveats

  There is a (theoretical) security risk, in that seeding /dev/random with /dev/urandom decreases the quality of the random data. In practice, the odds of this being cryptographically exploited are far lower than the odds of someone attacking the OS itself (a much simpler challenge).
  This may adversely affect battery life, since it wakes every second. It does not hold a wakelock, so it shouldn't have a big impact, but let me know if you think it's causing problems. I can add a blocking read to the code so that it only executes while the screen is on. On the other hand, many of us attribute lag to lacking CPU power. Since this hack eliminates almost all lag, there is less of a need to overclock, potentially reducing battery consumption.

  Reviews on Play Store seem very positive.

    From the comments I don't think that article is conclusive. See also discussions on Google Group for more technical reads.

  Having read a bit more there are two reasons this might work:

  1: An application is using /dev/random when it should be using /dev/urandom. This is unlikely to have any real significance, and even if it did the bug is in the app.

  2: Keeping the CPU at a higher clock. This can also be done by changing the scheduling profile on any rooted phone.

  So I don't think this is the right 'solution' to whatever problem people may think they have. This is of course just my opinion/understanding.
