[Epic 4G Android Development] chuckdez:
do you have apps running in your sdcard?
[Epic 4G Android Development] murso74:
nope... i'm gonna reboot and hope that fixes it. didnt' reboot before because i was tryign to troubleshoot the problem while it was happening

i think its related to me losing my ringtones (which are on my SD card) unfortunatly unmounting and mounting the SD card did nothing so i dunno how to fix that
[Epic 4G Android Development] ac16313:
Run the media scan in the dev tools app

And earlier in the thread someone posted a grep command to see what's being constantly accessed on the sdcard I was looking for it but couldn't find it:(

Guys,

Last I checked, this was a CM9 thread ;) Not a battery thread, not a "you did this so I'd do this" thread, not a "Mine's bigger than yours" thread.

I have left some of the battery posts here as there is some good info there. Rest all is gone.

Lets stay on topic and enjoy the spirit of XDA.

Thanks.

Even though I turned off pulse notifications, the setting does not sick and the notifications keep coming back. If this a known issue? If not, how can I fix it?

Thanks.
[Epic 4G Android Development] wtogami:
It did for us.

The MMC wakelock seems to be falsely blamed for other things. For the CM devs turning off the blinking notification LED eliminated most of the mmc wakelock that we saw. It is possible something else exists that is similarly causing MMC to be blamed.

Menu, Home, Back, Search buttons

If I missed this I'm sorry.

I'm looking for a way to change the backlight timeout on the Menu, Home, Back, Search buttons on the face of the phone. In other ROMs there was a setting were those buttons would go out with the screen timeout. I can't find the same or similar setting in CM9. Am I missing something?????

Thanks for the help

In summary, optimizes the memory performance and L2 processor cache. By default its configured to use the minimum 128kbyte L2 cache on the ARM Cortex-A8. The Epic4g processor (ARM Cortex-A8 s5pc110) comes with 512kbyte L2 cache.

It is very light use though.. I typically would get around 13 hours and it would be dead. That would be with about 1.5h - 2h screen on time. Having JD turn off my wi-fi seems to save a lot.
[Epic 4G Android Development] Jesse6749:
Anyone tried the wifi hotspot on alpha 4??, I tried it and did not work. I am not asking for it to be fixed but will wait till this works later and the rom is a bit more stable. Otherwise I love the rom, but I need the wifi hotspot for work so I am going back to CleanGB 1.1.2 for now.
[Epic 4G Android Development] sonarchist:
..........wifi hotspot works just fine, has worked consistently on all CM9 alphas.....Q: you running a stock kernel w/ this? Not all non-standard custom kernels allow consistent hotspot.
[Epic 4G Android Development] brooksyx:
Works fine for me.
[Epic 4G Android Development] Jesse6749:
Thanks!!!

Hmmmm!! Maybe I will try it again and maybe do the factory reset wipe 6 times instead of 3 times. See if that gets the wifi hotspot working for me LOL!!!!

Thanks Guys for the quick replies :p;)

I noticed you have 100mhz sticking....any idea how? mine is most definitely not, fresh flash, stock kernel, no themes, etc.

[Epic 4G Android Development] KennyG123:
The first time I tried it it turned on then right back off. I rebooted and tried again and was more patient and it turned on, off then back on and stayed on.
[Epic 4G Android Development] Speedin07si:
Nope have no idea how... I have never had a issue with 100mhz not sticking untill I played w/ a 3rd party kernel for about 5 hours and i couldn't get it to stick at 100mhz. So I reflashed alpha 4 to get CM9 kernel and 100mhz sticks again.

I've been playing with different governors to see which one i like.
[Epic 4G Android Development] stir fry a lot:
You only have to wipe once. Only older versions of CWM needed multiple wipings. Try this method of a clean install. Make sure you flash your new rom immediately afterwards since you'll effectively a nothing but a shell of a phone in your hand with this method.
[Epic 4G Android Development] StoneRyno:
Hopefully I've not come off as defensive as I try to help others with their battery woes.

Mines been the top of the list too so I'm going to try the below suggestion and see how it changes various things.

I'm going to try this too. I thought it would be nice to have the LED notice but I honestly don't think that I actually use or benefit from having it as the notification sounds nearly all of the time are what alert me to new notifications.

By running do you mean simply stored on the SD card or actively using one or more of those apps? The reason I ask is I have the same very rarely used apps I always have on my SD card since I started with the alpha builds of CM7. And recently with CM9 is the first time I have seen anything out of the ordinary consuming battery.
[Epic 4G Android Development] arod404:

I am loving CM9.the devs have really done an awesome job.I have one issue that's on the tracker and I know they definitely have bigger issues but I realize I haven't seen any posts of someone saying they're going back to ec05 over it so maybe I'm doing something wrong? My Bluetooth connections will not play music. If I try Pandora, Google music, slacker,etc... It'll play one song then just skip and be unable to play the next song.it makes the sound like when your CDs used to be scratched.sometimes it won't even start playing at all.this issue is not present in builds before ics.like I said I still prefer and am using cm9 as my daily, but NPR all day is starting to depress me.any help is greatly appreciated :-)
[Epic 4G Android Development] nimitz87:
I had this problem, few questions is your phone plugged in when this happens?

have you had the problem making phone calls and losing data?

toggle airplane mode do anything?

what I did was go into the dialer options

pretty sure the combo is something like *#*#4636*#*# if not do a search on here I don't have my phone in front of me to check

go into the options and toggle data on/off this seemed to fix the problem temporaily but upon reboot would go back to doing the same thing.

I finally ODIN'd back to stock re rooted, flashed fresh download and it seems to have fixed quite a few problems I was having, mainly this, and 100mhz sticking, not sure if it fixed the promixity sensor yet haven't tested.

Hey fellow CM9 Users

In an attempt to keep the development thread as clean as possible, other members have created threads for asking questions to other users.

Here is a tip thread in the General Forum that KennyGlass123 created:

for some reason I can't get 100 mhz to stick. every time I go to performance menu it goes back to min 200 mhz. do I check persist after reboot? I never had this issue before.

I'm running stock kernel with v6 supercharger.

thanks.
[Epic 4G Android Development] chuckdez:
Those changes can't be made to a ROM already compiled. You'll need to compile the ROM with those compiler options.

Last time i provided a ROM ole Zu slammed it without trying it, he acted like I stole it some how. Have him compile it since he is well versed on ROMs.
[Epic 4G Android Development] slimpyman:
anyone getting a problem when sometimes plugging in, the phone will seem to reboot and stay on the boot loading screen indefinitely? my wifi is on when this happens. only resolved by a battery pull.

the reboots also sometimes happen when im switching applications... btw, is there a way to limit how maNY active recent app thumbnails i can have at once? ive aquired sometimes around 16 of them! not sure if its affecting my performaNCE
[Epic 4G Android Development] bit1:
How do we change these values? Is this something we would get when building our own build from source? Is it something we can terminal emulator or root explorer modify? thanks Noob here
[Epic 4G Android Development] dnathan13:
I realize that Zu stepped on your toes, I read the other thread and he was way off base and didn't know what he was talking about, but that was only one or two members, not everyone here. Could you perhaps give more insight as to how to input the information you provided? Does this need to happen in ADB or terminal emulator? Do we need to have SU permission. For a lot of people you just posted gobletygook, but we want to try it if you give more info about how to do it.
[Epic 4G Android Development] fromchaos0646:
had this issue too. it stopped with alpha3. do a clean install from a full charge, drain it, let it die, and charge it all the way back up again. ive heard people say that it was fixed with a3 and others say that it was fixed when they let the battery die. im on a4 with samurai and i use the v6 and kernel tweaks. my settings in the performance have stuck properly, including 100mhz and settings in control freak have stuck as well.
[Epic 4G Android Development] Ragnar:
This is going off topic, if you want to discuss how to compile a rom go start your own thread. The mods have already stated it and have actually pointed out out other threads where users can help other users. This is the development thread for cm9 and should only be used for that.
[Epic 4G Android Development] DeeODoubleD:
Yes! I have issues with native wired tethering on alpha3 & 4. I suggest using the Wired Tether 1.4 that mkasick posted a while back. You can search and find it in the epic apps forums. It works great!
[Epic 4G Android Development] murso74:
if you don't know how to compile a rom then you can't do it.. he said as much. unless the CM9 devs deem to roll these changes in or someone else creates a kanged rom there's not much you can do with it.

Is there anyway to change the boot animation? I took the original boot animations, and added my name in part of it. Kept the same amount of images and the file size is still the same, however after I zipped the folder back up and went to put it back in the media folder, the boot animation wont work anymore.

Any idea why it wont work?
[Epic 4G Android Development] thomasskull666:
There are lots of threads on here relating to bootanimation creation, so I would check out one of them. Did you make sure to use 0% compression when zipping the files back up? Most compression tools have a "store" option, which is what needs to be used in bootanimation .zip files.
[Epic 4G Android Development] Orion78:
Yeah I tried everything, And yes I saved as store and still no luck. I have made sevral of my own before that worked, so I wasnt sure if it was a CM9 issues or what.

PLDSIZE != Cache Size

I suspect PLDSIZE of 512 is incorrect.

https://github.com/CyanogenMod/android_bionic/blob/ics/libc/arch-arm/bionic/memmove.S#L54

#define PLDSIZE	(128)	/* L2 cache line size */

PLDSIZE is not the size of the L2 cache. It is rather the size or "length" of the L2 cache line.

Your own quoted link and this other guide says the L2 cache line length is 64 bytes.

Not sure if anyone has noticed this, i know it has been discussed. But i do not know if this was mentioned specifically. As we all know wired tether is not working in the current build, but it did work once. I was using 2 then went to 4, and no mas. Tried 1, works but 4g is not in the status bar so nix that. I did not fully test 3 since at the time the kernel i had for that was corrupted, without tether didnt bother to dl again. So if any devs know exactly why 2 works but the newest doesnt, i hope this helps you in some way. Either way thanks alot for all the progress with this phone, first Android device I ever owned and I could not imagine life without it. You guys rock.
[Epic 4G Android Development] Shinydude100:
I'd like to share an issue I've been having. Not sure if it's Carrier or ROM Related. I suspect carrier but here goes. Texting someone in Spanish with accents causes the recieved message to be separated as if I spaced everything out on the receiving end. As well as recieved texts in Spanish tend to sometimes come jumbled. I'll re-test and post screenshots. Perhaps someone else on Virgin Mobile can verify this, or someone on Sprint can test this to see if it's the entire Sprint network, or ROM related. Thanks.

Notice: I am sharing MY issue with this CM9 thread before posting under CM issue tracker so I won't waste dev time looking into something that may/may not be related to a rom issue. Feedback from users rocking CM9 is much appreciated.

And yes, 160 split is on. Something peculiar is that when accents are added before I send, i notice that the counter goes into what looks to be mms mode.
[Epic 4G Android Development] Speedin07si:
Idk about spanish issues but the jumbled part. If its just a buch of symbols and letters to make non sense. It should be by default but make sure your text app it set to split messages larger then 160 characters . It might solve the issue.

This afternoon my phone beeped at me that the battery was low ( which it shouldn't have been ) then shut itself off. A few minutes later I turned it on and the battery was at 56%. Anyone have an idea on tracking down what happened? I've had nothing like this on any of the alphas.

On stock alpha 4
[Epic 4G Android Development] DeeODoubleD:
I've had this happen on alpha3 and other roms as well. I found that while deleting cache and delvik before installation of a rom and such that deleting the battery stats gets a fresh reading on first boot. Especially if you're already at full battery.
[Epic 4G Android Development] ashbuly:
Actually, it says it can be 64 or 128.
[Epic 4G Android Development] Shinydude100:
I use to have this issue on stock battery, turns out it was bad. And it only got worse. I use to think it was CyanogenMod or a bad battery calibration. Turns out my battery was pretty fried.
[Epic 4G Android Development] chuckdez:
I stand corrected, got a little ahead of myself.

Okay, I'll build both and see if there is any measurable performance between the two. According to the ARM documentation the correct setting can reduce cycles and increase performance.

Really hope you're wrong, I've had no other battery issues and 16 hour days. But thanks anyway I'll keep an eye on it.

Lost Ringtones - Temp Solution?

Today I joined the ranks of people who suddenly appeared to "lose' their custom ringtone files. They just dissappeard - nothing new, others have posted about this - but I found a temporary solution that I have not seen mentioned -

Using a "ringtone maker I downloaded from the market, I was creating some new ringtones to replace the ones I lost. After saving one or two, I went into system settings, sounds, phone ringtones - and there were all of the old ringtones I thought I had lost along with the usual CM9 ringtones - apparently by saving a new file, it reconnected the ones I thought I had lost previously.

I don't recall seeing anyone posting a similar solution - but honestly, while I have been pretty dilligent about reading this thread, I may have overlooked it - so forgive me if I am being redundant. This obviously is not a permenet solution to the greateer problem for why ringtones are being lost in the first place, but it is a quick and easy way to get them back if you do lose yours.

if you feel you lost your ringtones and want to try to find them again - try creating a new ringtone with one of the various programs you can download from the market (I use a program called "Music Ringtone" that I downloaded and saved a long time ago - I looked to see if it is still avaialble and it is not in the market that I can see - but it does work great. You can download virtually any song you can think of by searching for it - then use their music editor to cut the piece of the song you want to use - you can assign one as your Default Ringtone after creating it or assign to specific content - after you ahve created a couple - look in system settings/sounds/phone ringtone - and see if the ringtones you thought you lost are back. Mine were - :-) I don't know if this will work you - but it did work for me -
[Epic 4G Android Development] funktron:
Forgive me if this has been posted and I missed it while searching for it - but does anyone else not have a Voicemail app after install?

Since CM (in general, not just this build) are AOSP based, they don't include any of the "stock" apps.
[Epic 4G Android Development] funktron:
OK, cool. Thanks for the quick response. I haven't installed a CM build before this one since the T-Mob G1, so I'm still catching up. :-)
[Epic 4G Android Development] Ragnar:
Actually I dont know how you missed it because its been mentioned 1000 times. But there is no vvm app for this. But if you go into the dialer settings into voicemail and make sure your phone number is in there you can simply hold the 1 digit on the dialer and it will call your voicemail or you can go to Google voice and use that for VM. Once set up correctly it will function pretty much the same.

EDIT: wow I type slow lol
[Epic 4G Android Development] bstevens23:
I believe having GOSMS installed also fixes this. I used to have this problem on CM7 and I had GOSMS saved to my SD card so everytime the phone rebooted I'd temporarily lose my ringtones until GOSMS loaded.
