    So you got this "Holo Launcher" on there, I have to check that out now and see if the old GO Launcher EX 2.85 comes back or not. Hmm.. I have to say that this rom is quite attractive looking just with the font change! I thought I had the Cyanbread selected in Theme Chooser but only see system colors.

    I just happened to come across this article today after installing the new kernel. Curious what the experience of others has been. The phone seems a bit faster to me, but according to this, the entropy change has nothing to do with it?

    Entropy Seed Generator Not All Its Hacked Up to Be xda-developers

    [...]
    The premise of the hack is that you can reduce lag by keeping a section of the Android file system (/dev/random) full of random bits so that the system does not have to wait for the file system to generate them. In theory that sounds great, and has shown some success in certain areas where lag was obvious, but it presents all sorts of other problems.

    It is for those concerns that we do not recommend using this fix. The fix itself in no way causes harm, and is near-placebo in its effects. CyanogenMod developer arcee posted information on the fix, stating that

    The only users of /dev/random are libcrypto (used for cryptographic operations like SSL connections, ssh key generation, and so on), wpa_supplicant/hostapd (to generate WEP/WPA keys while in AP mode), and the libraries that generate random partition IDs when you do an ext2/3/4 format. None of those 3 users are in the path of app execution, so feeding random from urandom does nothing except make random well less random

    There are valid concerns about lag and how the Android OS handles them, and there is discussion currently ongoing within the Android Code about this, but this fix does not address those issues and instead gives performance gains through boosting CPU speed. The developer himself stated that this could in effect reduce battery life, since the hack is waking the CPU every second.

    The entropy fix in this kernel is not the same as seeder. It is a fix for the underlying problem of why something like seeder was created in the first place to keep the entropy from dropping. It does not cause the CPU to wake more often than before like seeder did and it is not possibly diminishing the randomness of /dev/random.

    Yaconsult, the discussion you have linked is about the seeder app and I actually agree with the CM developers that it is an ad-hoc fix. I wouldn't include in MiRaGe. See my earlier comments here.

    What I have included in the MiRaGe kernel is a patch that addresses the entropy depletion problem in the kernel level taken from LKML. It will probably be included in the mainline Linux kernel soon. This patch is not even specific to Android. So, skeeterfood is right. There is no change on the Android side since the problem is addressed at its root.

    The XDA mod posts the following follow up comment on that thread:

    "faekplastik3s a month ago
    You're jumping the gun yet again, it's still inconclusive.

    jerdog76 Mod > faekplastik3s
    No we're stepping back from endorsing it BECAUSE it's inconclusive."

    The mod isn't saying that it doesn't work, I think he is saying that it doesn't work for everyone and that some performance increases are due to constant polling of the CPU and have nothing to do with entropy. Also, gingerbread and below access dev/random more often than ICS and above - the platforms need to be split when users report success or failure of the hack.

    And like mrg666 stated, this isn't an Android issue, it's a lower level issue than that.

    Is there is an option to make (media volume) the default instead of ringer or was it just a BACKside addon?

    I just can't seem to figure out what's constantly using my entropy then. I've disabled/force stopped/uninstalled all but the basics, rebooted, and still get 150 - 200 for entropy_avail...

    Thank you, mrg666! This is the smoothest and fastest this phone has ever run!

    I had already switched to holo some months ago and agree it's great - light, fast, and looks good.

    Entropy checker shows ~3500 - not sure why some seem to be having problems with it.

    You also have the best instructions in the first posts at the top of this thread - everyone should read though them all when they install. Link2sd works great! By following your instructions, I can put all the apps I want on the phone and not have any space problems. I just partition the sd with one fat and one ext4 partition, install link2sd as one of the first apps and it moves everything that can be moved to the sd automatically - I don't even need to think about it.

    When I think back to how crappy this phone was when I first got it with froyo from VM and the battery wouldn't last a day and the memory was full and I couldn't install more than a few apps and nothing could be moved to the sd card, it's amazing! Job well done, Sir!

    Enmod, are you sure seeder app has been removed properly and no links left in / dev? If that is not the cause you might try a clean flash after a nandroid backup and restore your apps/mods/themes one by one.

    I wasn't sure if I uninstalled it properly, so I just went with a fresh flash after flashing LeslieAnn's Prep_for_new_rom zip. Flashed the latest build, flashed official gapps, booted, and went into the terminal emulator to use the cat command that would give me the current entropy. It was ~3500 as expected.

    So I then went about messing with system settings, configuring them as I normally would. The first and only app I installed next was the entropy checker app mentioned earlier in the thread. It displayed the entropy building up to ~2100 slowly as you described, which confused me. Why was the upper limit suddenly lowered by ~1400? Disregarding that I exited the app and tried the cat command again, to see if something went wrong. Entropy was dropping with each successive use of the cat command, starting from ~1700 and dropping by ~30 each time; I stopped when it hit ~1500. Knowing this was the wrong behavior I tried the checker app again, out of curiosity. It displayed the entropy available with an upper limit of ~400, decreasing eventually to the range of 150~200 I mentioned before.

    I tried uninstalling unnecessary apps, like live wallpapers, Gallery3D (I was going to for QuickPic), VoiceDialer, even the checker app. But when I went back into the terminal it showed the same results as the checker app: 150~200

    Was it something I changed in system settings that is causing all this entropy use? I only adjusted the Notifications Power Widget, changed my CPU settings to 245-806, and activated WiFi, setting sleep policy to Never...I doubt it though. Idk what else could be keeping my entropy at a limit of 150~200 though.

    Note: a CPU setting like what you posted will use way more battery trying to ramp up to you Max setting than just setting Min to 480MHz.

    480MHz Min and 768MHz (give or take a setting either way according to the quality of the CPU) Max, is actually where the best battery off charge time is at.Good performance as well.

    Lol I know about the whole 480 min thing, I've just found that for my uses I actually notice more drain on 480 min, if you can believe it. As for Max, you think 806 is inefficiently high? It's worked for me.

    So here is a question, how can you judge battery drain like is there an app or anything that will measure it?

    These links you're referring to in /dev.....
    What would one look for to delete? and/or what shouldn't be there?
    I installed the Seeder app almost a month ago now. I did the uninstall via Link2SD and since then was when you had made the kernal update. How would you know if there is somehow any sign(s) or traces of it left?
    I took this SS when it was going well...however, when I do check it at times, it still seemes to be all over the place. Doesn't stay "low" though as some have mentioned here.

    Linking /dev/random to /dev/urandom was another method used along with seeder. If you have not done that don't worry about it.

    Regarding entropy going up and down, that is normal. The kernel patch is not overaggressive about keeping the entropy level always at high values. When there is high demand the entropy level can go low, this is expected. Keeping the entropy always high will cost cpu load and battery life. But I have not observed depletion with this patch yet. That is the point.

    Any thoughts about it being constantly low though, like it still is for me?

    Hello, great rom. I'm having a bit of trouble that I'm not quite sure is completely related to the ROM. Out of the blue my phone completely stopped being able to send or receive MMS. I'm at my wits end and wanted to see if any of y'all could help before I resort to wiping everything and trying a different rom. I updated to the latest rom, but that didn't help me any. I'm currently using Go SMS Pro, but it won't let me send or receive them via the stock messaging app either. The last MMS I received was on Feb. 5th, and I haven't been able to download one since. Since that time I haven't installed any new apps or changed any settings. I'm completely baffled as to what's going on here. Also, it isn't one specific carrier either. I've had friends send me messages from att, t mobile, and virgin mobile and none have worked.

    Install the Harmonia ROM or the Resurrected Bumblebee. Then everything you have on that ROM.
    If it fixes the problem, you have issues with the ROM. Re-download the ROM and double check the md5 sum. Then wipe and format everything but the SD card.

    If you still have issues it's the network.

    Not likely the ROM, there have been unconfirmed reports of SMS/MMS/Data down by a number of VM subscribers. Might check VM's Facebook/Twitter page for the operational status in your particular area.

    I don't know why I didn't think to check the VM facebook page. Apparently there is a "national picture message outage" expected to be resolved sometime tomorrow. I'm hoping that's the case! It's been driving me crazy, and I really did not want to switch ROMs.

    Thanks for the quick responses, you guys are the best.

    I have been running an older version of Mirage on my phone with no problems so I installed a newer version on my wife's phone about a month ago. She immediately started having battery drain issues. It ended up being caused by having Bluetooth on all the time. She has Bluetooth in her car so she just leaves it enabled on the phone. This wasn't an issue on the stock rom. I tested my phone by leaving BT on and it drained the battery quick too with nothing connected to it. Anyone have an answer for this?

    In the mean time, you can try toggling the Airplane mode. My 3G was randomly dropping to 1X, while my signal was still displayed as being good, repeatedly last week. I toggled the Airplane mode, and 3G would come back. However, all seems back to normal--consistent 3G connection--for me as of yesterday.

    I have Mirage for about 3 weeks now. Are there new updates for this rom since then? I forget to constantly check in on what's going on. ;(

    Also, my phone seems to only last a day or two before something happens and I'd have to restart the phone or it restarts on it self. Is that normal? I'm currently overclocked 480min 748 Max interactive. What are the suggested advice on overclocking on this rom?
