  1. My phone is always lag and not enough space in Ram memory as i often found that most of my apps often runs by itself such as services whenever i clear it even by using pro launcher with it's go power master. Is there a way to improve our phone performance so that it won't be so laggy or stop so much autoruns?

    1. You can try Autokiller Memory Optimizer : https://play.google.com/store/apps/details?id=com.rs.autokiller&feature=more_from_developer#?t=W251bGwsMSwxLDEwMiwiY29tLnJzLmF1dG9raWxsZXIiXQ..
      You can also stop running process manually by go to setting > app > running apps. You can choose any app u want to stop here.

    1. sorry i'm not really understand your question.
      there is no need to flash anything in swap or unswap.
      swap or unswap just need to replace a system file.
      thats all..
      no need to flash anything

  7. swap with sd card class 4 can or not? Sory my english bad.

    ReplyDelete
    Replies
    1. Yes. you can swap with sdcard class 4.
      I recommend swap your phone using class 6 and above because it have faster write/read speed.
      But, class 4 is ok. Not too slow and not too fast also.
      If you swap using sdcard class 4, make sure not to install too many useless apps since it can slow your phone down

    1. It is normal if using sdcard class 4.
      Delete the pics using a computer. Connect your phone to a computer and delete the pics.
      Let me know if it's working or not.

  9. Cannot find that picture... Idon know where the file location.. Pic details 'unknown'.

    1. Can you delete the pics using My File. If cant, try to use gallery to delete it.
      If it's still there, try to connect your phone to a computer.
      Then, copy all folders and files in your sdcard to your computer.
      Format your sdcard.
      Copy and paste all your folders and files that you copy to your computer earlier to sdcard.
      Then, find the pics that you cant delete before. It should be gone now.

  12. Hi,
    I appreciate some help and advice. I already swapped the memory. I tried to find the storage info like one you screen captured above but couldn't find it. I look under setting > storage, but it different from yours. I looked under Applications > Memory usage, but still different.

    Mine is 2.3.6 android version. Under USB debugging mode, I can only see 2 type of storage (internal 1.7GB and 14GB). Where does the other 1.7GB internal memory goes? I know that the phone have two 1.7GB internal memory, but couldn't find it via the AndroidZip or when connected to PC. Any ideas?

    1. Cm9 has a features for swapping internal/external no need to do this tweak LOL

      How to swap Cm9?

      Setting>Storage>Storage Configuration>Check Use Internal storage.
      Restart Cm9 then you external was already you internal memory.

      Delete
    2. Will save the settings when I flash cm9 to cm10 ?

      Delete
  17. I tried this on CM9a7 and it also left me stuck at the boot screen. I re-applied the cm9 zip file using the clockwork recovery menu in order to repair the filesystem.
    I realised that I'd applied it to /etc rather than /system/etc but both ways prevents the OS from booting.

    I eventually used root explorer to edit the /system/etc/vold.fstab file in a text editor and hand-edited the mount points.

    1. This maybe cause u dont follow the steps carefully.
      There are only 2 ways to solve this problem.
      1. Restore the backup if u make a backup before doing this.
      2. If u dont, you need to flash back to stock rom: http://mygalaxywonder.blogspot.com/2012/07/how-to-flash-and-install-stock-rom.html .
      Also, make sure your phone is rooted before doing this.
