    mostly things that most people overlook or don't know, like with titanium backup I just quoted myself in above, I just updated, I'm going to better organize my info and make it easier to read and follow.

    a good majority will come from CVPCS who wrote up a similar thing on his wiki, which I don't think many have seen.

    ongoing:android_myths [CVPCS Android Wiki]


    ^Things like that that most people don't know, or other tips that you find/found while having an android device, like the thing about titanium that I posted.

    Okay well something i just helped someone with a few minutes ago if you have larger apps like games or miui music or even dolphin browser and they randomly close without a force close message then you can increase your vm heap size to allow the larger apps to stay open here is a copy and paste from the post here

    They have apps that do it but in my opinion easiest way is to do it by hand cause you can then set whatever you want so i just use root explorer then go to the build.prop file this is located at /system/build.prop
    long press the build.prop and select open in text editor
    scroll down a bit till you see
    # This is a high density device with more memory, so larger vm heaps for it.
    dalkvick.vm.heapsize=<some number>m

    Then just change that some number to what you want the recommended usually is 32 i think but i just go big :) and put it at 52 ha just so i could run miui player and what not but if you feel more comfortable using an app just go to the market and search vm heap size there are a few apps that can do it for you.

    Can also be done through terminal but that's a bit more crazy works a little like this though just for knowledge purposes here's a quick script to change it to 52

    #!/system/bin/sh
    #

    BB=busybox
    $BB sed -i "s/dalvik.vm.heapsize=.*/dalvik.vm.heapsize=52/g" /system/build.prop
    $BB sed -i 's/hw_dalvik.vm.heapsize=.*/hw_dalvik.vm.heapsize=52/g' /system/build.prop

    then you would just save that as a file and place it at /system/xbin make sure to set your permissions and then run it through terminal emulator by just typing su and then the name of whatever you named the script

    Thanks for that man, VM heap size is in my thing.. lol but not how you covered it, and as a side note the ROM will be sporting the feature to change the VM heap size.. :)

    But exactly many people don't realize what the VM heap size is or what it even is for/does. so thanks for the input..

    LCD density is another tweak in there don't remember the benefits of that one though ha

    Don't plan on putting all tweaks and tips, i would make another thread for that though if there is intrest, for the most part this is mostly aiming to do what CVPCS did in that link, and add a few of my own things.

    Here i got another one if your battery life is starting to get bad you can wipe your battery stats which often improves your battery life this can be done in all of the recoveries i'm aware of and through terminal with the following commands

    $ su
    # rm /data/system/batterystat.bin

    (you don't type the $ and # they are done by terminal)

    LCD Density is effectively a Screen Resolution increase/decrease.
    To be honest, I see no real functional (every day) benefit to this tweak due to the fact that; what it does if you increase resolution is only good for basically icons on main screen and launcher. It is not all that usefully, effective with Widgets and if you have games, they can come out looking terrible. Likely this is due to the fact that it on many models, does not use screen real estate properly, landing you in a shrunken screen at higher resolutions.

    Those who have primarily icons on their screens and do not use many Widgets or have many..... any screen heavy games how ever may... (may) enjoy the effect.
