I am experiencing shutdowns or crashes when my phone is idle with b8. Since this was not initially the case in the 1st week I wonder if it might be an application I installed.
[Captivate Android Development] Jirv311:
Finally figured out what was eating my battery. It wasn't bad but I certainly noticed a difference today. I usually get right at about 16 hours on a full charge, but right now, I'm showing 17 hours unplugged with 52% battery left. Just by turning off GPS. Everything else at default. WiFi sleep policy, etc. Just thought that was nice. :D
[Captivate Android Development] Exostenza:
What is a wifi sleep policy? I noticed after leaving my wifi on over night it sucked down the battery and spare parts said that the wifi was running 100 percent of the time. Is there a way to make it go off while the phone is sleeping? This was the case with my Milestone, but it did it on it's own.

Thanks.

Set Policy to "Sleep when screen turns off"
[Captivate Android Development] BLWedge09:
While that is definitely the correct procedure to adjust the wifi sleep policy, the best setting for battery life has been widely debated. I personally find that setting the Wifi sleep policy to "Never" yeilds the best battery results. Maybe it's because I live in a low to moderate service area, but my wifi definitely sucks down less battery than the cell radio. Since I have widgets that update, etc., making wifi turn off and widgets update over 3G causes decreased battery life. As with anything else, YMMV.
[Captivate Android Development] crolling:
Agreed. As always battery conservation comes down to individual usage. I don't use widgets (or anything else that auto-updates regularly), so having the policy set to sleep when screen is off works well for me.

Edit: Don't mean for this to turn into a "how to conserve battery" discussion, just wanted to let Exostenza know how to change the sleep policy so they could experiment for themselves.

Create a ringtones folder in the root of your SD card... And put the MP3s in there. It'll scan and recognize them.

For those looking for a good reason to stay on Cog and not Perc... Upcoming changes:

"NO GPS (network location still works, good for general location)"
[Captivate Android Development] Exostenza:
I just wish that Cognition would be 3.5g compatible like perception is.

Also thanks guys for the answer about wifi sleep policy.

Anyone know how to stop the first half a second of my ringtone being dampened and also how to stop getting text messages for my voice mails?

running cog 2.3B6. disabled voodoo by placing a folder named disable-lagfix in the voodoo folder. rebooted phone and now it's been sitting at the AT&T world phone screen for about 5 minutes?

nvm, pulled the battery and rebooted. voices came on and it worked. had a little hiccup there i suppose.

although now the market is gone, how does one acquire that?
[Captivate Android Development] TexUs:
I wondered about the ringtone thing, too. I think the easiest way is to download Audacity to edit the MP3... And add a couple seconds of silence to the beginning of it. I've just been too lazy to do it myself yet.

And about text for your voicemail???? Stock doesn't do that. Are you using Google Voice?

Wired Headset not working in 2.3b8

:( hi does anyone face this issue of not able to hear with wired headset with mic on this new rom. It was working fine with 2.3b7 fine. I used headset and tried to call people but not able to hear anything. Please help.

I have searched this thread but did not find any thing. Please help.

Thanks in advance

What does that mean? Perception 9.5, the current build, has no gps issues, other than what all our phones do. You are referring to 99. a TEST version that has that issue, not v9.5.... he also said he was releasing several other TEST versions for people to play with.

"Upcoming Changes:

- Backup entire sdcard to timestamped folder before flashing

Build 99 Changelog:

Rebased on JL5

Lock Screen Chooser

Gingerbread Clone

NO GPS (network location still works, good for general location)

Build 9.5 Changelog:

- no more overclocking issues because its gone!

- no more sdcard corruption

- no more charging death

- no more random reboots

- everything else is the same"

Get your facts straight before reporting them, please. People, try cognition AND perception and decide for yourselves.....

I have flashed several roms, but not a kernel/modem combo, is there a correct order to flash them in (e.g., modem then kernel or kernel then modem)?

Edit: Nevermind
[Captivate Android Development] techjeep:
Gingerbread Theme?

Does anyone know if there is a working Gingerbread theme for 2.3b8? I looked in the Themes and Apps forum but none of those seem to work for Cognition. I like the look of Perception, but I use the GPS quite a bit and the battery drain is just a little more than I like.

One that does NOT have a percentage in the battery icon is preferable.

BLN!?!?

Alright, I'm on Beta 7 because I like the backlight notificaitons.

Except...they stopped working.

Literally just stopped.

I haven't changed or flashed anything.

Does anyone know how to fix this?

Would it take a simple kernel reflash or something?

PLEASE HELP! - BLN is the reason I'm staying on Beta7, because I love that feature.
[Captivate Android Development] richsale:
I've been on 2.3b8 for a few days and everything worked great except voice on phone is all gobbled. I switched to P9.5 and the the calls keeps dropping out. I want to go back to 2.3b8. My question is are there any other modems I can try on 2.3b8, and if there is, where can I find out how to flash just the modem. I have flashed a few roms but never just the modem.

I'm not the first to report this, all those who have posted about it, their post has been passed on or ignored.

Also lost 3G, out of no where. Reflashed modem (JI6) and still no 3G.

Only option now is to reflash the rom.... 3rd time now :(.

About to give up and go to stock rom with voodoofix only.....

It is frustrating that we don't have a solid ROM that LASTS. I mean come on, each rom is like on it's 10th beta or something haha. I'm not complaining or blaming the devs, they do a great job as it is, I'm just frustrated in general because of all the re-flashing I've been having to do as of late.
[Captivate Android Development] Jirv311:
Ummm, welcome to the "Development Forum". :D

You don't have to reflash all the time. You can simply One-click Odin to stock and stay with that. No more Beta build. Remember these devs are not paid, only collecting donations. ;)
[Captivate Android Development] RockRatt:
To hopefully answer some of the recent post here, perception 9.5 has evrything working smoothly and has the 3g and 3.5g speeds. Cognition only has the 3g speeds. Cog.7 used an i9000 parts in it and is different than any other cogs. Perception uses ACTUAL froyo rims ( most of them at least as far as I remember) and is why it now has speed and stability. Perception 99 is a test rom and gps is not working. It is basically a gingerbread clone at the moment. Cognition does NOT have or is NOT based off of a actual froyo version but is based off two samsung leaked. Efsions that DG got a hold of and made better. The only Cog rom I have not tried yet was Cog 8 and only because I have been trying every single Perception build and the Tech Demo build of gingernread port. In my humble opinions both Cog and perc. Are awesome. I have used some that needed rework or bad bugs. But with trying every build of Perception and Cognition (except Cog 8 as previously noted) Cog n64 was the best for me, and Perception 9.5 was the best Perception rom. I actually really love Perc. 99 and the only downfall os not working gps at the moment. Knowing DG that will vet fixed in the next build I bet. These are just my takes on both Cog and Perception from my own personal experiences. Your may differ since each phone seems to have its own android mind and some roms work great for some and not for others. I keep all the rims I have tested and when all else fails I alelwayz go back to either cog 2.3b6 or Perception 9.5 for speed and stability. Hope this can help some decide to try out the other toms or switch between them. But then again I am a flash shore and these are just my own personal experiences.

[Captivate Android Development] musicalmindz:
ultra noob question, do the 2.3xx builds represent gingerbread or are those just updated versions of froyo? Read through tons of this thread and just trying to understand if I should just odin flash that JI6 build, go with a 2.2 cognition build or go with one of these newer 2.3xx cognition ones. Thanks :)
[Captivate Android Development] n19htmare:
I understand that and trust me, I've donated plenty....

by Roms that Last.... I was comparing to Cyanogen's ROMS. Meaning, ROM is only released when it's tested and stable.

In here, it's like all over the place... For example Cognition has gone Captivate only, to I9000 to OC, to NON oc, to this and to that, all in the Beta1-Beta8 etc. it should have been SEPARATE for each, and a separate thread.

Same goes for Percetion 9.5 and all prior to it, where things where added, and removed etc. I understand it's beta but when i see a Beta 8, i expect it to be more stable and have more features then a Beta 7 or 6. But often times there's MORE broken stuff in newer betas.... i just dont think they should be named that way.

What I'm saying is it comes down to maybe the naming schemes? Maybe Beta 9.5|99 shouldn't be beta 9.5, it should be Perception Gingerbread Clone in a whole NEW thread. Because it's actually a STEP down from 9.5, because you lose functionality etc.

So I guesssss, what I'm asking for is better version/naming schemes.
[Captivate Android Development] AdamSHayward:
n19htmare, I for one am somewhat offended by your post.

If you've been following this thread it should be quite clear in its progression. I have probably read 80% of the thread and have had no confusion at all. DG does what he wants to do and we reap the benefits. His ROMs are top notch. If this thread doesn’t appeal to you can stay stock or try another.

Also had you taken the time to look 9.5 and 99 are separate ROMs.

I officially hate this damn phone, after hours of trying to get the phone connect to the computer then trying to get odin to recognize it then after a master clear it tries to brick while flashing back to JF6, finally get that sorted and then the computer then cant see it again, get that sorted and the final straw is it now says signature verification failed. Any help would be appreciated. And MY GOD I forgot how slow this damn phone was stock, I really dont know how people put up with this thing in stock form.

Re: Driver issues

So I had a lot of frustrations with one of my Win7 boxes and Captivate/Samsung drivers. I eventually went to dev mgr and forced the driver from the Cog FAQ(beginning of this post) onto the Samsung devices. After I did that no more crappy usb issues (btw, if you are having issues and have Keis remove keis driver set/suite, reboot and force driver as I mentioned).

i asume by signature verifcation failed you mean that u tried to run an update zip under reinstall packets and it said that. that happend to me before if the case and what i did was i went under settings and reformated sd card. i then redownloaded the update zip becuase sometimes it to me seems to corrupt the update zip if you reuse it to many times. the reinstall update zip and should read it then.

sort of not related to Cognition

I have a question for DG, but feel free to answer if you know it (and arent DG). I am running CDE 3.1 from way back in the day and I prefer it to all other roms, my only issue with it is that bluetooth doesnt work and I was wondering if anyone knows how to take files (and what specific files) from cognition and inject it into my .zip of cde so that I can get bluetooth working on that rom. I dont want to switch to cognition just for bluetooth as I only use it when in my wife's new car (hence why I hadnt needed it before).

My specific issue with bluetooth is that calls are statiky. Bluetooth music works fine but calls have a really bad static or hang up entirely.

feel free to PM me if you have a solution and dont want to waste space in this thread.
[Captivate Android Development] zaures:
Anyone have any insight as to the signature verfication failed issue, reformatted internal sd and still no luck.

Got it to work finally just had to flash to a newer rom and go through clockwork recovery like normal... weird :/
[Captivate Android Development] s44:
Offended? Don't be silly.

The general lack of stability releases is a real problem among Cap ROMs. b8 is the first Cognition in ages that *only* fixed stuff and didn't add a bunch of other big changes.
[Captivate Android Development] n19htmare:
offended at an opinion and offended at what I believe is wrong? I've donated to devs, I've got paid version of titanium and Rom manager, I do my due diligence, and in doing so, I also give suggestions to the devs and the community.

I'm not bashing the devs, as I said earlier, they do PLENTY that some of us wouldn't be able to.

I was just pointing out the short falls of the captivate in the developers world and I was merely suggesting that we have a ROM that is tweaked and made BETTER with every revision and made stable... instead of injecting new beta stuff into it and calling it the next beta build. A good example is is Cyanogen's Rom. A single rom is made and once stable it is left ALONE in the STABLE section. But development never stops, it stays in the experimental and nightly build sections.

That's all that I ask for when I say a Stable Captivate rom. RIGHT NOW, if I had to pick, I think that rom would be the Cognition v2.3b8.

20 Roms, 20 kernerls, 20 different modems....trying to mix and match this and that...it's tedious work not just for Developers but for users as well.

This is a forum, place to spread knowledge, suggestions and opinions, don't be offended.

[Captivate Android Development] greyhulk:
I just installed this rom...

And I...jizzed...in...my pants!

Seriously, this ROM kicks ass. I figured that by the time Samsung/ATT got around to releasing Froyo for the Captivate, it would be buggy and probably missing features (tethering), so I rooted and took the plunge.

This ROM is super fast and smooth. The only issue I had was a weird random reboot right after I started installing apps. I chalked that up to my Hardware getting acquainted with the new image. They seem to be friends now. I'm stoked that the AT&T crap is gone, too.

I'm a little confused as to why the Beach live wallpaper was left off, but it's easy enough to download (I think it's cool, maybe not everyone does).

One question: I read tons of posts on here about the radio/download speeds, but I'm confused. Will my download speeds on AT&T be slower with this ROM? I'm in my office building now, so I can't really test it.

Everything else about this ROM kicks ass.
[Captivate Android Development] loraque:
No, your speeds should be the same as they are with stock. The talk is likely in reference to the file (called a modem) that controls the antennas in your phone and how they connect to the frequencies available. The main issue is this- on a Captivate phone (not a i9000 Euro phone for example), we do not get to enjoy the high-speed 3.5g upload capability (HSUPA). This is reserved for the iphone 4 ATM here in the US, so our phones are using normal 3g for upload. Cognition is based on a Captivate software load and uses Captivate modems, so no HSUPA.

DG's other ROM, Perception, is essentially Cognition based on a i9000 ROM, that uses different modems to allow HSUPA (which does have some side effects on your connection as a whole, but is MOSTLY to do with uploading). The success of using the i9000 modems seems more erratic in that some areas work best with certain modems, while other areas are dead with those and work with others... and so on.

I spent quite some time trying i9000 ROMs to enjoy the speedier network, but was plagued with always having SOMETHING not working correctly, or at least not as good as here on Cog. I would get network skips on streamed music far more frequently on any i9000 ROM, would get BT issues with some, call issues with others... it was a total crapshoot. I eventually got frustrated when each new modem (every other day it seems!) would be worse than the last, and eventually I had no idea if JK3 or JK4 was the last decent functional one for me. Or what.

Went back to Cog for a 100% functional phone. I need two phones to hack like I want to apparently. I am unwilling to have the wife give me crap about my phone not working 100%, as I am the resident geek and have an image to maintain. Perception 5 I think was the best in that line... the current 99 build using JL3 is the worst performing modem yet for me in that it was the first one to not receive calls. I did have data stackups on previous ones... but no voice calling is somewhat hard to work-around on a phone for me! And yet, from the posts, it is working great for a good number of people. I really like the look on it with the Gingerbread coloring.

YMMV.
[Captivate Android Development] greyhulk:
Okay, so we don't have 3.5g. That was what I was taking away from the discussion. That's unfortunate, but everything else about this ROM works so well, I can live without it. I have a feeling it will STILL be better than the official ROM when it's released.

One issue I just noticed: I have the new version of the Gmail app (2.3.2) and the header is not floating. I uninstalled an reinstalled the app with no success. I read in a few other places that Sense UI phones have this issue. I anyone else experiencing this on the Captivate?

Battery life

I recently got my Captivate and tried a few roms and ended up liking this one, but I have a problem. When I used my GPS app Navigon to drive home for the holidays, I noticed when I unplugged the charger from the phone, the battery was almost dead.

I know Navigon uses offline maps and can possibly be a cpu hog and I'm wondering, how did the battery get depleted while using Navigon even though it was connected and charging while I was driving? My only guess is that the overclocked CPU was draining the battery quicker than it could recharge.

Any help would be appreciated. thx

Lagging

I was getting random lag when using this ROM before I switched to another. I ran a linpack to see what was up and I was getting 14+ then I would get only 4 then it would go back up to 14. I know linpack scores are generally crap but it definitely showed the lag.

I want to come back to Cog but only if this can be resolved. Any ideas?
[Captivate Android Development] TexUs:
Can you reproduce it or was it one-time only?

As a general rule... Don't complain about it until you know it can be reproduced :p
[Captivate Android Development] shutterbc:
Regarding battery life and GPS, I think you might notice that happening anyway even with the stock ROM. Supposedly the GPS module (Broadcom BCM4751) is a relatively low-power unit, but I noticed rapid battery drain using it even straight out of the box.

I believe the drivers for GPS are part of the baseband modem. So if GPS power management is somehow broken in the I897UCJxx - JI7 modem, then it's possible to get better GPS / battery performance via a future update.
[Captivate Android Development] Shoey Peachew:
It happens every time, unfortunately.

ok, I'm not sure what I'll do but wait and see. thx
[Captivate Android Development] Exostenza:
Alright can someone please give me some insight into this. I have done the bump charge thing and wiped my battery stats and am draining it for the first time since I wiped my stats. From 25 to 24 percent it took long than the last 15 percent on so. It looks like my last 25 percent will last much longer than the first 75 percent. Will this change once I have depleted it and charged it back up so the phone has better stats or is this something I just have to deal with?
[Captivate Android Development] n19htmare:
once you deplete the battery and fully charge it a couple of times, it will calibrate the battery.

Right now your battery is uncalibrated. the Lithium batteries have a cutt 0ff voltage, basically, the "indicator" tries to measure your maH from that cutoff.... if you flash your phone, it is possible to throw that calculation off. But it all comes back once your calibrate the battery.

Use your phone till it dies, then plug it (use a wall charger, if you use your computers usb, you'll be waiting a LONG time) until ALLL THE WAY TO 100%, this is crucial because it's going to measure and calibrate from that.
[Captivate Android Development] s44:
Your car charger probably isn't being registered as a charge-only device (by shorting the data lines). Check the phone to see if it thinks it's on AC power or USB (computer).
