I am using cm10.1 alpha 8 with completely inbuilt setting. Means I havent changes any settings like freq, governer etc in rom after I flashed it :)

Okies. :) Don't know why i faced such issues. But with ondemand governor it working all good.




i take it back...battery life too seems pretty good on this rom....the second cycle gave me more than a day :good::good:

Wow! 6 hours screen on time! That too on JB? How? :confused:
I'm sure it's new battery. But my new battery gives max 4 hours screen on time on JB.
Any mods or something?!:p

So you are not facing the backlight issue any more?

Sent from my Huawei Ascend Y300!


well as i mentioned here http://forum.xda-developers.com/showpost.php?p=44207625&postcount=1381

the backlight bug is partially solved.....say 70% of the time, when i lock the screen, i dont face any backlight issue....the remaining 30%, the backlight issue appears (screen lights up) for say 40 secs - 1 min...after that it turns off ( hence the low battery drain overnight).....maybe it has something to do with deep sleep..who knows

Another observation : during calls, the backlight stays on...and the phone heats up for some reason....so that seems to draining the most battery

Asking for a fix is awkward when the issue itself is so complex :p

For mods, i use Direct Inject......it is said to improve battery life but it also improves performance....so whether that counters it, i am not sure


As for why i get that much screen time, the screen on time is say 60% reading ebooks ( which is not cpu intensive)..that along with managing the brightness and using night mode while reading at night gives me 6 hours....my battery is 1 n a half year old btw

Generally improve the camera (especially HD video record)

I agree with abde. Our SL need cm10.1 oc kernel so it will be much smoother.The HD video record for me is working fine. Sometimes reboot to recovery didnt work.

Bluetooth Car Stereo for Phone calls

Wow...u are now God for those devices also ;)

Hi Dhiru

Thanks for this awesome Rom. So far i would say this is the best ROM with battery, i have tried stock, DDLF2,DDM1 all the customs rom with those Base, i have not had a smoother better experience than Alpha 8. Thanks a lot for the good contribution. I am not sure if i can post this querry but still going to:-

I use Bluetooth for phone calls using my car stereo, this is very critical, though the BT connects, stay connected when a call is going on, the moment call ends, ti disconnects, i understand this is due to deepsleep, but if i recieve a call, the BT connection revives but get active only after 1 min or so and by the time i ahve take the call through the headset, once BT activates the call then gets transfered to the car speakers.

this is find strange, any help on this will be deeply appreciated.

thanks

So, with this Alpha, the 1280x720 video recording is smooth? No stuttering? I was waiting for that. Can you confirm this?

Video playback of camera recordings with HD 720p is stuttering very hard.
SD 480p is smooth, but the sound isn't synchronous to the image.

So the issue remains the same as in A7.


Problems concerning the backlight issue:
I had both backlight issues on A7, but now they are gone.
I did a clean flash in CWM, nothing else.

Backlight issue hasn't been fixed yet.

Hi Dhiru,

One more interesting observation w.r.t backlight. (I am still on A7)
- The backlight bug comes up even when I am charging a switched off phone! If I press power button, the screen switches off and after a few seconds, the backlight comes out. I am charging over USB cable from my computer.

Does that mean it has nothing to do with Android as such, but with the kernel? Let me know if you need some specific logs for this particular use case.

rgds,
Dipu.

Alpha 8 is fine although I experienced less errors with alpha 7.
I've had some reboots, last some days ago, so maybe that's not a problem.

But when using Apollo at some time it stop playing and I'm unable to play any kind of music either using other players. Play button seems to do nothing. That happen until reboots.

I will try to provide some logs

Bluetooth issue now solved: blueth me on

i did my own research, the bluetooth cuts off completely due to deepsleep, found an app which can enable 2 settings
1) keep bluetooth always on
2) switch on bluetooth only when a call is to made or recieved.
both these setting works beautifully and has been able to get the phone awake from the deepsleep.

the app is called "blueth me on", i have tested it to work with Alpha 8.

regards

    Installation Instructions


    IMPORTANT! READ BEFORE FLASHING!
    1. If you flash this ROM from Stock ROM, it will wipe data due to different partitioning. The device would reboot while flashing and resume again.
    2. Once on this ROM, the most effective way of going back to any other ROM would be to repartition from Odin.
    3. While converting the filesystem, your efs that has your IMEI is backed up to /emmc/backup/efs. Keep a backup on your PC just in case.
    4. Incase if you don't get a network signal, check if your IMEI and Baseband are proper. If not, go back to stock and try again.
    5. Do NOT use Odin to flash Modems. Due to different partitions, Odin will screw up your existing MTD setup.


    Stock ROM
    1. Flash CWM Compatible Kernel (CF ROOT)
    2. Reboot to Recovery.
    3. Wipe Data / Factory Reset.
    4. Select the ROM zip from your SD Card and flash.

    6. Reboot to Recovery Again.
    7. Flash Google Apps.
    8. Reboot

    Any other AOSP ROM (CM7/MIUI/CM9)
    1. Reboot to Recovery.
    3. Wipe Data / Factory Reset.
    4. Select the ROM zip from your SD Card and flash.
    5. The device will reboot and finish flashing.

    I have finally purchased LG Optimus Black P970. Big Thanks to everyone who has donated.

    I have received the phone yesterday and I have built CM10.1 and installed it. I started playing around with the HWComposer and testing out few stuff. After hours of debugging with the P970, I finally came to know what's the problem that was preventing HWComposer to run on Galaxy SL. I immediately made the fixes and viola! It works.

    The UI is butter smooth now with almost no visible lag. The performance is same as that of P970. However, I have been facing issues with getting the HD video to work. There are some display subsystem errors and the screen turns off when a video is played. Once this issue is fixed, I will roll out the next release with HWComposer.

    Alpha 7 is out. This would be the most stable and complete release so far.
    65
    New build of Alpha 6 is out. You could download it from the Download section.

    You will never have seen your phone perform so well as that of new Alpha 6 :cyclops:
