    My phone becomes dead ( phone dont wake up with any key press and not able to recieve and dial call and messages) when i leave my phone to 3G network, if any app is running phone remain normal:), if not its dead after some time and eats battery and on 2G connection it is perfect.
    here i explain what i have done with my phone,
    i have upgraded my phone from 1.6 to 2.1 from lg care many times, done hard reset and i made external partition EXT2 on sdcard and rooted by myself, app to sdcard is working correctly.
    i dont know whats wrong with this.:mad:

    your question is not clear. Are you saying that your phone battery goes down when you leave it with 3G??

    Well, 3G eats the battery more and you'll end up finishing up your battery within a day if you leave it on 3G. Thats why you need to click 2G only option to save battery life time.

    no, it doesnt drain out whole battery.
    when it is dead after then i have to take out battery and reinsert it , battery level goes down only by 10 to 15% only, i want to say if i keep running an app then my phone is ok at 3G but when i dont i goes dead after sometime, even if battery is full. when it is dead there is no other way to turn it on except reinserting the battery, please read the previous post carefully, i keep battery full.

    Its very peculiar behaviour of your phone :thinking:. I can't think of a reason. How long does it lasts when its on 3G?? I was on 1.6 later 2.1 now 2.3.3 never had such problem.

    is there any malware running on your phone doing this nasty stuff??.

    Why dont you unroot your phone, then factory reset then try again.

    If they doesn't show up, trying Importing from SD (Go to Contacts>Press Menu buttone>Import/Export>Import from SIM Card)...

    I think it's better to uninstall Autokiller Memory Optimiser, Task killers are harmful in many ways...

    With Auto-Starts, you can you can select which apps will start during startup & block apps from starting at Startup... It's for advanced users & stopping critical apps from starting at startup can cause malfunctions.

    Swap is like "Virtual Memory" or Page File (Windows) in PCs, Uses a part of the SD card as RAM, You can enable it via that app (Instructions in the last section, "Swapping", of the CyanogenMod 7 thread) Well, It won't work as "RAM", will just give a slight push...

    Terminal Emulator lets you execute commands in your phone

    Check out this thread of "Theme Chooser" themes: Themes Working On LG GT540 CM7 - xda-developers

    Don't know about Internet calling, Tablet tweaks are in Settings>CyanogenMod Settings>Tablet Tweaks

    Set Min CPU Frequency to 245Mhz & Max CPU frequency upto 845Mhz... DON'T set more than 845Mhz, It's safe to go upto 806Mhz... You're phone will be faster but it'll get hot & battery will drain fast

    Go to Settings>Wireless & networks>Mobile Networks & Untick "Data Enabled" when you don't wish to use internet...

    Phone type keyboard here & Android 2.1 keyboard here

    You can try Barcode Scanner, Google Sky Maps, Google Goggles, Metal Detector, SoundHound, Swype(You have to signup in their website), Wireless Tether... Try browsing the Market, there are more cool apps there...

    I upgraded my phone and it just work amazing:D:D, but there are some apps that are not working:thinking::mad::thinking: like

    multi mount sdcard


    saved messages in SIM card, i cant find them,

    phone doesn't wake up when plugged and unplugged charging

    LG IME (Phone type keyboard as in android 2.1) is force closing everytime

    applanet is force closing while searching sometime,

    all call recorder sometime works and sometimes not(It worked very fine in 2.1)

    in cyanogenmod settings>systems>update notification force closes every time,anonymous statistics is also force closing,
    can you explain the performance in cyanogenmod settings,
    can i add more lockscreen styles,

    i wish to change black colour status bar to my favorite colour, is it possible,

    Where can i get flash player for Cyanogenmod 7,

    Are these bugs,
    But still this OS is great but with these little problems

    Download it from dudeman1996's post & install it via any file manager

    you have to install this one via Recovery (Install zip from SD)

    Multi Mount SDCard won't work in this ROM

    Uninstall QQPlayer & re-install from the Market

    Open "Messages">Press Menu>Settings>Manage SIM Card Messages.. Your messages should be there...

    It doesn't for us too

    Did you flash it via Recovery?

    No idea, I don't use it, Try reinstalling

    no idea

    As ours isn't "Official CyanogenMod" these options doesn't work

    CyanogenMod Settings - CyanogenMod Wiki

    You have to edit framework-res.apk in system as far as I know

    Either you have to find a modded SystemUI.apk or edit it yourself...

    We have ARMv6 processor, Flash won't work
