  1. It’s very nice and happy to have a separate place for Viper.
    please make compatible this VIPER for 512 MB ROM phones.
    It is working flawlessly the song, but when screen off, the music playing is cut-play-cut-play,…like this…

    1. Chandu,
      That is probably CPU governor fault, not mem.
      Try changing the governor, some governors tend to limit cpu when screen is off.
      For example, on Motorola Defy, frequencies are 300/600/800
      If Governor limit it to 300 or 600, it will cut the song.
      Have to be at least 800.

      1. Very very thanks for your suggestion.
        Mine is LG optimus black (p970) model. Now using No-Frills CPU Control for changing governors or something.
        Please suggest me some best governor and I/O scheduler.
        I have available Governors are (dysinteractive, interactive, ondemandplus, ondemand, lionheart, performance)
        And I/O schedulers available are (noop, row, cfq, fiops)
        As you said, I will set minimum frequency for 800 and maximum for 1000 Ghz.
        Thanks in advance..

        1. I/O Scheduler is not of grave importance in that matter.
          As a CPU-Gov give “interactive” or “lionheart” a try. If all fails, go for “performance”, though it’ll be a battery-drain-monster.

          I don’t know No-Frills and its options, but you could also check out if there is an option to configure the govenor. If there is you could maybe adjust the off-screen-behaviour. If there is no option, try Pimp-My-Rom or Trickster-Mod or one of the likes.

          Be aware, that if you don’t have a custom Kernel installed, these settings may have no effect at all.

    2. do you mean skips? It causing by the kernel/rom side of your android. too much battery saving can cause stuttering/skips issue, something that deal with the processor power and how many core it runs. Super audio driver needs at least dual proc to run, if only 1 core run it will lags like hell…

    1. Performance governor will keep your CPU running at the maximum frequency- this will of course negatively impact battery life however. ROW scheduler has worked great for me too. My phone is Samsung Galaxy S Captivate i897, 512MB, 1000MHz Cortex-A8 with NEON.

  3. hi your mod is the best i have found on the net but if some more features are added then it would be the best, such as Dolby like sound i know that we can use i r s to make it sound like that but it should be in dhe viper it self

  4. I have Viper4Android on all my devices. Reinstalled firmware on this Asus Memo Pad 8 181c, rooted as usual with Chainfire’s SuperSU, installed Stericsons BusyBox Pro. Every time I try to install V4A, any version, and have tried all reinstalls of busybox, checked SuperSU (all correctly installed) it says cannot install driver due to either not being rooted correctly or busybox is broken??!!!! Never have seen this but found others posting with this problem, all seem to be current.
