Just a small something, when I'm playing music and go to the lock screen, the album art is going off the screen.

Weird my phone turns off by itself when put into the pocket after a while. Could be a heat issue since it's pretty hot here where I live. Especially these last few days when this started occurring.

Edit: For clarification, it shuts off and doesn't reboot.

I have the same problem. Also, wifi drops randomly in standby and says authentication problem. Happened on multiple routers. Forces me to turn off wifi and back on. I'm on a fresh install of latest build.

No offense intended at ALL, but I wish people would stop giving out this advice. Wiping battery stats (ie deleting batterystats.bin, which is the same thing that the option in CWM does) has absolutely zero... ZERO effect on battery life. It also has ZERO effect on the battery life that Android shows you in the status bar.

The 'battery stats' (better known as batterystats.bin) is ONLY used for the per-app battery usage tracking in Android.

But don't believe me, believe it right from the horses mouth:

(you'll have to copy and paste the link below, XDA won't let me post links because apparently I haven't posted here enough... hpmh!)

With that being said it IS a good idea to fully charge and then discharge your Li-Ion batteries once in awhile - they tend to live longer that way. :)

Here's the deal. It doesn't change the physical way the phone or the battery work, just the way that the operating system is reporting it. Yes, the file is deleted in certain circumstances when the phone is nearly charged, in which case this won't help. In the case where people's charging habits don't coincide with that possibility, this may help them out.

In my case, after doing this, Android reported a 30+% improvement. Up from 10+ hours to nearly 14 before expiring.

So, that is more likely the current baseline for this ROM. People who turn off Wifi or total cellular data (or both) could get much better battery usage. That's where Juice defender comes in and is good at. However...

When I am at home, I have both Wifi and data radios going but not GPS or Bluetooth. I don't need mobile 3G data but I do want to get Google Voice push notifications, which rely on a data connection (not sure about cell), so I can't turn on airplane mode. IIRC, you should be able to turn off 3G data radio without turning off cellular (GPRS) so that's next on my list.

So, obviously, this is still a work in progress. I've just started using this ROM, so I apologize in advance if this is a waste of time.

I just noticed a bug. When playing music that is plugged into my stereo receiver using a 3.5mm to red white connectors, the audio always stops. Like it just stops during random times. I don't have this issue using regular earphones, so it is really weird. Does anyone have this problem?

I do.. For my car stereo, it's very annoying.

I do wonder why.. It doesnt matter at what volume I put it in.. On GB it doesn't do that.. And in previous builds of CM9 is didn't either.

It is Mixer ICS theme (props to T679noob for the suggestion) with minimalistic text "icons".

The Mixer ICS theme is installed from a downloaded .apk. It has (at least) one bug, with the alarm display, but it has a really nice look. For CM9/ICS only, I think.

(In fairness I should call it an incompatibility, not a bug. When I applied the theme it warned me about "missing assets for this screen size" but I clicked "apply anyway".)

How would you describe your usage? I still can't believe you are getting over a day with that battery! :eek: I can't wait for mine to come in..

Left my phone laying on my bed the whole day.. Wifi/network on. Was receiving notifications. The giant steep dip at the end was because I started to use it. Tumblr/music/Google voice. Stock battery..

Dunno if this is considered to be good or not...?

What the other poster was saying is that it doesn't even do this. It just monitors how much each individual app has been using the battery for each session. It doesn't have anything to do with the OS reporting it or displaying it.

In my case, after doing this, Android reported a 30+% improvement. Up from 10+ hours to nearly 14 before expiring.

My battery drainage has varied wildly with similar usage patterns. I am still testing it, and it seems Talkatone was using quite a bit of battery, but I'm still not sure. It's pretty hard to pinpoint something like this unless the programmer tells you there's a bug in their software. Unless is absolutely obvious, you need to test many times, so you get some sense of a statistically valid answer. A 30% increase after you changed a setting might not mean anything, and from the information in the post linked, it likely doesn't.

Apparently, the later Samsung phones use their own chip to monitor and report battery usage, ignoring Android altogether. So, YMMV, as it obviously is.

New build so fluid. Could be the ROMWipe but whatever.

Also, any music player that saves your playlists? I'm using WinAmp but when I restored from TB the playlists don't restore.

    This is a port of CyanogenMod 9 (Android 4.0.x) for the Samsung Exhibit II 4G. It is very much a work-in-progress. There are no guarantees whatsoever that it will work to your requirements or that it will progress beyond its current state. Major kudos to Arco68 for his help in getting this going; you would not have this ROM except for him.

    Here is a video by dennis96411, showing CM9 on the Exhibit II

    What seems to work
    Phone
    Wifi
    SMS/MMS
    GPS
    Bluetooth audio
    Amazon Market
    HW accelerated display
    Headphone detection
    Microphone detection
    T-Mobile Wifi-calling (works for most)
    init.d support
    CIFS networking
    Camera (Stock Camera only, 3rd-Party apps mostly don't work)
    Haptic keyboard feedback
    Market/Play
    Gmail
    Browser
    Screenshots
    Streaming video

    What does not work (NO ETAs)
    911 Emergency Calls
    Torch app (check thread for alternatives)

    CM9 for the Galaxy Exhibit is NOT vulnerable to USSD dialer exploits.

    Vanishing text
    The content of text buffers sometimes disappear when touched (messages in: gmail,yahoo,fb). Wiping cache has fixed this for some. Long-press of back key and restarting app for others.

    Facebook
    Facebook sync is not included in AOSP. 3rd-party apps are available in the market.

    3g vs 4g
    Cyanogen Mod views UMTS as 3g whereas the stock Exhibit II rom views it as 4g. Even though you see 3g on your status bar, your actual speed should be unchanged from stock.

    Changing band preference
    In dialer, enter Service Mode via
    *#*#2263#*#*
    Click to expand...
    Click to collapse
    You should see:
    [1] Automatic
    [2] WCDMA Band Preference
    [3] GSM Band Preference

    To force WCDMA only, tap option 2, on next screen tap option 6 - WCDMA All

    To force GSM only, tap option 3, on next screen tap option 7 - GSM All

    You can use the back button to verify your settings took effect. To exit, tap menu button, quit. This change does not survive a reboot. If you use this frequently, save it as a contact.



    WIFI Problems
    Wifi is working fine for almost everyone using CyanogenMod 9 Galaxy Exhibit build (and also for the Galaxy W). If you are one of the very few having difficulties, a possible fix has been posted that may help: WiFix Manager.

    Installation
    Installation requires a CWM-based recovery. Download/update Galaxy Exhibit Custom CWM Recovery here.

    Updating CyanogenMod 9
    Once you have a stable install you're happy with you can apply future updates w/o any wiping. If for some reason a wipe is required, I'll make that known.

    Download CM9 Beta
    Core2idiot's CM9 Nightlies

    Google Apps
    Google Apps gapps-ics-20120429-signed.zip .... Mirror

    Kernel sources

    Copy the downloaded cm9 beta and gapps zip files to your internal or removable sdcard.

    Back up your data.

    Start Custom Recovery (cwm): Press & hold Vol-Up, then press & hold Power. Shortly after the plain white Samsung logo appears, release both buttons. Recovery should start after the color Samsung/T-Mobile Exhibit logo.

    CWM Keys:
    Home key = enter
    Back key = back
    VolUp/Dwn = highlight choice

    If installing over a non-CM9 ROM you must do a ROMwipe before installing.

    Select "Install zip from sdcard." Choose the cm9 beta zip from sdcard or external sdcard, depending on where you placed it. Highlight the cm9 beta zip file then press Home. Confirm the choice and installation will proceed. You may also install Google Apps (gapps) at this time. Gapps does not include all Google apps. Those not included are available from the market.

    Please DO NOT PM me with support questions! Post them in this thread!

    Compile CM9

    Portions copied from Motorola Droid X CyanogenMod Wiki

    Thanks to Arco68 for hand-holding and patches. Any mistakes are mine.

    These instructions assume that you will be using an Ubuntu 10.10 Linux system (or a close relation, Debian, Linux Mint,etc). Setting up a Linux partition or creating a Linux VM are beyond the scope of this post.

    First, Install the Android SDK

    Next, install the linux build packages required. I install using apt-get:

    For 32-bit & 64-bit systems
    apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool

    For 64-bit only systems
    apt-get install g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline5-dev gcc-4.3-multilib g++-4.3-multilib

    NOTE: gcc-4.3-multilib g++-4.3-multilib is no longer available for Ubuntu 11.04 64-bit, but should still build without issue.
    Click to expand...
    Click to collapse
    NOTE: On Ubuntu 10.10, and variants, you need to enable the partner repository to install sun-java6-jdk:

    add-apt-repository "deb http://archive.canonical.com/ maverick partner"

    NOTE: sun-java6-jdk <> open-java6-jdk!
    Click to expand...

    These instructions assume an "android" directory located in your home

    Install repo
    Code: 
    mkdir ~/bin
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo 
chmod a+x ~/bin/repo
    Download CM9 source
    Code: 
    mkdir ~/android/system
cd ~/android/system
repo init -u git://github.com/CyanogenMod/android.git -b ics
repo sync -j16
    This can take hours. When done, ~/android/system should be at least 11Gb in size.

    Next:
    Code: 
    cd ~/android/system/frameworks/base
git remote add arco git://github.com/arco/android_frameworks_base.git
git fetch arco
    Download kernel source
    Code: 
    mkdir -p ~/android/system/kernel/samsung/ancora_tmo
cd ~/android/system/kernel/samsung/ancora_tmo
git init
git pull https://github.com/arco/samsung-kernel-msm7x30.git

Repeat the pull command occasionally to obtain updates.
    Download ancora_tmo device directory
    Code: 
    mkdir -p ~/android/system/device/samsung/ancora_tmo
cd ~/android/system/device/samsung/ancora_tmo
git init
git pull git://github.com/Jocala/device.ancora_tmo.ics.git

Repeat the pull command occasionally to obtain updates.

cd ~/android/system/vendor/samsung/ancora_tmo
git init
git pull git://github.com/Jocala/vendor.ancora_tmo.ics.git

Repeat the pull command occasionally to obtain updates.
    Set up prebuilts:
    Code: 
    cd ~/android/system
./vendor/cm/get-prebuilts
    Applying cherry-picks
    You'll need to gain at least a rudimentary knowledge of
    using git and github. Teaching this is beyond the scope
    of this howto. Cherry-picks must be re-applied after each
    repo sync.As time goes by they also get merged, so it may be that some
    cherry-picks are no longer required. You can check their status here.

    Attached to this post is a script (reposync.txt) that will do a repo
    sync then apply current cherry-picks. I keep it in my
    android/system directory. Rename and chmod 0755.

    Set up your environment & build

    Code: 
    . build/envsetup.sh
lunch cm_ancora_tmo-userdebug
brunch ancora_tmo
    Building takes at least an hour. If everything worked, you should have a
    out/target/product/ancora_tmo/cm-9-SOMEDATE-UNOFFICIAL-ancora_tmo.zip file

    ============

    CCACHE

    If you have room on your build system you can speed
    your builds up considerably by using ccache. ccache is a compiler
    cache. It speeds up re-compilation of C/C++ code by caching
    previous compiles and detecting when the same compile is
    being done again.

    Install it with apt-get: sudo apt-get ccache

    Set environment vars for Android use:
    (I put these exports in my .bashrc)
    Code: 
    export USE_CCACHE=1
export NDK_CCACHE=ccache
    Set a cache size of 10G for optimal results:

    Code: 
    ccache -M 10G
    Check the status of your cache with the command:
    Code: 
    ccache -s 

Returns:

cache directory                 /home/jocala/.ccache
cache hit                         106673

    This is true. My phone always says 3G, but switches to H when downloading, then goes back to 3G.

    Also, even though he's now ignored, Nightlies aren't forced updates. You can flash over the update whenever YOU want. They're just always supplied on a nightly basis in case there have been any changes to the repos. Since it's CM9 there probably won't be many new changes, but its still offered...

    It's always hilarious when a newcomer shows up who absolutely knows it all, refuting everything we only think we know about our phones.

    I think the idea of nightlies is great, I never had the resources. I've replaced the OPs download link with a link to Core2Idiot's nightly page.

    On another note, I've decided to keep my Exhibit as a dev device, so I'm going to continue busting my head with 911 for a while at least. I'll post if I have any breakthroughs.
