Did you have this problem before?

I had this problem with the OC/UV kernel. Flashes the other one and this solved my problem. This was with b7 though.
[Captivate Android Development] ratflinger:
Screw that - Gingerbread is in the oven now & DG is one of the bakers
[Captivate Android Development] s44:
Is it *that* hard to read the first page (heck, at this point the very top thread!) in the general section?

See here (history of issue, ending up with app that basically solves it) and here (if the phone was made before November 6, you can get an easy exchange for this problem).
[Captivate Android Development] mark72501:
OK. Well, when I was in the 3G area earlier today if I went to Settings > About Phone > Status ... it would show, under Mobile network type, HSDPA. So maybe it was HSDPA just showing 3G on the status bar?

I hit 1.1Mbps today in one spot, with 5 bars of 3G, but I still feel that is slower than it should be. However, that may be a network issue and not the phone's and/or ROM's.
[Captivate Android Development] Srikar_NBK:
Thanks for the clarification. That atleast lets me understand why, these ROM's are better performing than the Samsung default build, one reason being rfs vs ext4.
[Captivate Android Development] CuriousTech:
B8 is the best so far except I can't seem to mount /system as R/W. Anyone else or should I just reflash and try again?

EDIT: Figured it out. Root Explorer couldn't do it, possibly because it's ext4, but it worked in shell using mount command.

$ mount -o,rw,remount -t ext4 /dev/block/stl4 /system

/stl4 being whatever cat /proc/mounts shows
[Captivate Android Development] torrin66:
B7 is light years different than B8.

B7 is I9000 based (non-captivate ROM)

B7 is Superfast

B7 has most of the issues related to I9000 (Bluetooth, Market issues)

B8 is a Captivate ROM

B8 is Fast (though not as fast as B7)

B8 has none of the I9000 issues

I went to B8 for stability and no I9000 issues.
[Captivate Android Development] torrin66:
You got it. That is the point of Voodoo, it allows for EXT4 file systems on the Captivate. It makes for a faster file system.
[Captivate Android Development] torrin66:
Errrrm, it is mounted as read only on my and I have no system issues? Why do you need system rw?
[Captivate Android Development] CuriousTech:
Mostly for customizing the framework resources.
[Captivate Android Development] TexUs:
Cog uses 5% an hour on battery.

Axura 10%.

Not sure what major differences are that cause this but Cog is still the best Captivate ROM in my opinion.
[Captivate Android Development] Copronymous:
I'm not sure about the headset, but battery life for me has been stellar.

After 20 hours of moderate use (browsing, texting, email and camera) I still have 50% left.
[Captivate Android Development] cumanzor:
Ahh, thanks for the clarification. I haven't had any major issues with b7. Bluetooth and market are working fine. Only problem I'm having is the accuracy of the gps.
[Captivate Android Development] newter55:
Moderate is such a relative term....my wife gets two days on hers with what she considers moderate.....I might get through a day without plugging in when in the car. Display time in relation to off charger time is a much more accurate representation unless you are one who actually uses one of these things as a phone.
[Captivate Android Development] derechbennoach:
Just a quick report:

Running B8.

Installed from stock, master clear etc.

Battery life great.

GPS: used GPS Restore app

Bought CoPilot

It works great. Fast and accurate.

No reboots on charge. Everything I use works.

I have not used BT yet. I am in the low IMEI numbers but no problem.

I have tried the I9000 roms and have had issues. I think the Captivate specific Rom and Kernel work best for me.
[Captivate Android Development] joeybear23:
Those numbers are relative.

With 2.3b8 I lose about 1% per hour with no use (in my pocket or on the desk) and can lose up to 1% a minute in heavy use.

During the week I have to charge every night, but I can go a whole weekend without plugging it in once and still have 30-40% battery left.
[Captivate Android Development] TexUs:
Axura was during the day, when my phone largely sits around and I don't do much messaging.

Cognition was during the evening in which I'm messaging everybody.

So the Cognition had more usage and it still performed twice as good.

My only complaint/issue at this point is the WiFi. It has always done this (on many ROMs), but I leave my WiFi on 24/7, and when connect it to my phone, drive to work, it won't connect to my work without shutting it off and on again. Anyone else's do this? I don't have a sleep policy.
[Captivate Android Development] loraque:
JK3 or JK4 for B7 wasn't it? Try some of the other modems and see if you get better GPS performance. There are a lot of i9000 modems that are decent, and one or another seems to work better depending on who you were in a former life.

Clear the GPS data with each new modem :).
[Captivate Android Development] loraque:
I have come to the same conclusion for my phone. I am somewhat convinced that the "spikey" network performance I would see using speedtest on HSUPA modems was not an artefact of of the measurement. I would skip streaming music too frequently to listen to it, incoming calls would go to VM without ringing the phone, SMS/IM would stack up as if I were disconnected. Of course when I wanted to use it, it always worked, so the problems were somewhat masked for a while. I was willingly looking the other way to keep HSUPA.

JI6 works great for me, better than JJ4. JJ4 gets some of the same skipping on data, while I can't point to a problem with JI6.
[Captivate Android Development] derechbennoach:
Now that you mention it, I have had this a few times on all of the Roms, cog b8 included. I cannot seem to force duplicate it. It will say the network is not in range. I turn off WiFi and turn it back on and it connects.

Not a big deal, but does uses cellular data when it should be using WiFi.
[Captivate Android Development] TexUs:
As with me: It's happened on all ROMs I've used. I don't know if they're all using bad modem files or what.

But if you go in the "long way" to see the status, I've had mine say not in range, or even "Disconnected" (today).

Turning it off than back on always fixes it but as you said, until you realize it, it's using the battery-draining cellular radio and using bandwidth (I've got unlimited but for those that don't this is a bigger issue) because it won't connect.

Not sure how this would be "fixed" unless DG or some other dev could make an app that increases the pinging or shuts it off and on when it can't connect (which would increase battery usage as well).
[Captivate Android Development] cumanzor:
JK3 yeah. How do you go around flashing a new modem?
[Captivate Android Development] Misterkeef:
Hello, first post here. I am running cognition v2.3b8. I just wanted to say I'm very pleased with all of the features of the cog rom. I am however experiencing a few issues like everyone else.

issue 1. The phone freezes after being charged over night.

issue 2. Network speeds on 3g are capped at aproxamatly 500kbps. A friends 2.1 captivate hit over 800kbps using the same speed test.

Other than that, just a few android market update crashes and some force closes after i restored some apps from titanium backup.

Thanks for the rom! I look forward to the next version.
[Captivate Android Development] connexion2005:
As long as full credit is given to DG, is there any issue with someone else also providing hosting for the downloads of the COG/Perception ROMS? I was considering having a ROM repository as well and never can get a hold of DG in PM's so I figured he or someone else may see this and know the answer.
[Captivate Android Development] mwerth11:
Bug?

My phone stopped auto-rotating the display after a few days on this ROM. Tried to toggle auto-rotation on/off & reboot. Still a no-go. Ended up re-flashing.
[Captivate Android Development] gordec:
Anyone knows how to disable vibrate on swipe for the lock screen?
[Captivate Android Development] dalavar:
Thanks for the links. Sorry I didn't read the general section. I flashed Cog right after turning the phone on. I did read the entire Cog thread first though. And the imei is 2750 so guess it's affected.
[Captivate Android Development] pinoymutt:
Unfortunately I've seen the question asked on different models and forums as well, and the answer seems to consistently be that there is no easy way to disable it (at least not from the UI). There is an option to disable haptic feedback for the pattern unlock, but not for the regular swipe screen.

Sorry -- probably not what you wanted to hear though.
[Captivate Android Development] rootnik:
After a couple weeks of messing with i9000 based roms, I am back to Cognition. While I enjoyed the speed, It all came down to battery life. Nothing I have tried is better than Cognition.
[Captivate Android Development] cumanzor:
I'm running b7, what's the best way to move to b8?
[Captivate Android Development] derechbennoach:
Same ole same ole

One click back to stock.

Master clear.

root

install Clockwork

(or use the update.zip from CWM installed from a stock recovery -- you can bypass rooting with this. Be sure to put your new rom on the sd card first.)

Use Clockwork to install rom.

Then reinstall your stuff from your TB backup.

Most of us have done this so often we have worn places on the screen and buttons.
[Captivate Android Development] cumanzor:
I have to flash back to stock? Odin kinda freaks me out as I've read you can brick your phone if something goes wrong.
[Captivate Android Development] derechbennoach:
It is the best way. I have yet to blow one up. Maybe I'm just lucky.

Just put it all in place on the external sd, and reboot to download.

Forgot: Oden to stock with a master clear.

Copy it over to the stock internal sd and reboot into recovery. Install the update.zip from CWM and then install the rom with it.

I think I can do it in my sleep.
[Captivate Android Development] Kanzeon:
Thanks. This was a pretty weird issue, so I tried reflashing and starting from scratch. Both problems seem to have resolved.
[Captivate Android Development] slvr00gt:
I hit the same issue with both 2.3b6 and 2.3b8. I use tasker to turn off wifi at night and while BT is connected. Every now and than wifi will refuse to turn back on
[Captivate Android Development] gkallivrousis:
Is there a way to get Backlight notification on cognition?
[Captivate Android Development] s44:
No, just flash the kernel and modem. Nothing changed on the ROM side at all.
[Captivate Android Development] Srikar_NBK:
Couple of others issues I see with b8

1) I see download speeds reduce from ~1.5 Mbps to ~700 kbps on this ROM. How did I test this ? Turned on USB tethering to my laptop and ran some bandwidth tests. Upload speeds have also gone down from ~400 kbps to less than 100 kbps. Not sure if it has to do with it being Captivate only ROM.

2) When I lock my phone with Wifi turned on and let it go to standby or whatever for a few mins and then when I unlock the phone, I can clearly see that the phone instantly turns on Wiki and turns off 3G. I guess once in standby or whatever, the phone turns off Wifi automatically and uses 3G. Does 3G suck more battery than Wifi ?
[Captivate Android Development] pinoymutt:
2 items:

1. What are you comparing b8 to? (What version?)

2. Yes, 3G typically does suck down more battery than WiFi. This behavior you explained is the default behavior for data (disables WiFi in standby). You can override this by going to Settings > Wireless and Network > Wi-Fi Setting > Advanced (from options) > Wi-Fi sleep policy. From there you can have it choose to keep WiFi on when plugged in, or never turn it off.

Please note that if you never turn off Wi-Fi that it will poll for AP's when you are out of range if you keep WiFi enabled. For this I would recommend a utility like Y5 Battery Saver, Locale, or Tasker that can automate when and where your WiFi is enabled and disabled.
[Captivate Android Development] mdoctor:
Get rid of Vibrate on unlock...

The only other option you have is to revert back to the Samsung's Original Glass Lock screen that was part of cognition in v2.3b4. If you like the glass lock screen, extract the android.policy.jar file from b4 and overwrite the existing one in b8 (its in the /system/framework/ folder). You will need root explorer or super manager for that. Once you copy the file over to the above folder, reboot the phone. The first boot will after the copy will stay on the cognition boot screen for a while, so don't panic. Eventually, it should boot to the glass lock screen in all its goodness (and no vibrate on unlock). Enjoy... :)

p.s. - after the copy and reboot if the phone is stuck on cog boot screen for longer than 10 minutes, then it would be time to panic. Would probably need a battery pull and reboot, or maybe even a reflash. So backup before you start the copy process, and don't blame me if you by some freak accident manage to brick your phone... ;)

Backup and Restore Question

Hi All,

Just wondering if I do a backup of my current ROM (Rogers 2.1 Captivate), can I restore from the back up (without any issues) after I flash Cognition? I am just asking in case if flashing Cog doesn't go smoothly, atleast I can revert without too much trouble (ex. ODIN).
[Captivate Android Development] patterson12123:
if im already running the newest cognition rom, would ryanza's one click lag fix do me any good?
[Captivate Android Development] mdoctor:
I use Super Manager. It allows me to mount /system as R/W in B8, and the best part about it is its FREE. ;)
[Captivate Android Development] Jikx:
Nope, as Voodoo lagfix is already pre-installed.
[Captivate Android Development] mdoctor:
NOPE! in fact you could potentially mess up your phone if you do use it...
[Captivate Android Development] cumanzor:
This is what I figured. Is there any tool, or do I use clockwork manager? I'll check around because I think I saw instructions on how to do it...
[Captivate Android Development] 4got2g0:
Ok so I've been reading these last few pages and understand the i9000 modem has its issues, but just for clarification is it compatible with cogb.8? I had the voodoo lagfix with bln and hsupa on the stock eclair rom and my upload and dl speeds were dramatically faster. I tried to install that same thing after flashing cog and bricked. If not i9000, is there a way to improve this?
[Captivate Android Development] null_x86:
Just wondering about it cause the mms thing is irritating with b4. Im going to flash later tonight to b8 or b7, depending on what works best. Hopefully the mms issue is fixed with those. What version did you flash to that worked?
[Captivate Android Development] random1204:
Facebook not syncing?

Has anyone had a problem with their Facebook account not syncing?

Randomly the other day my phone removed all of the info/pictures from my facebook account out of my contacts. I have no idea what caused this. I didn't touch any settings or accounts or anything.

Can anyone point me in the right direction in order to fix this? :(

OH BTW - Unlike my signature, I'm currently running 2.3b7.
[Captivate Android Development] Srikar_NBK:
Odin version of Froyo 2.2.

Thanks for the Wifi clarification. I normally make sure I turn off Wifi when not in range.
[Captivate Android Development] Blueback22:
I am running B7 with the supercurio modem and kernel fix (basically same as B8).

The problem I am having is that since adding this modem, I have noticed that I am not getting vibration notifications on Gmail or Good for Enterprise emails. I have checked all my notification settings (both general and program specific) and they are all set right.

Is anyone else noticing this? The only thing I can connect it to is Cognition.

BTW: I am super happy with Cognition. Props to DG!
[Captivate Android Development] hoopas:
Wow. For me this a first.....before bed, turned off all data & sync, turned wifi on & was at 70% battery. 8 hrs later, still at 70%. Kudo's on your work DG;-)
[Captivate Android Development] rcmatos:
Having trouble with my alarm. It won't work, any ideas?
[Captivate Android Development] k2snowboards88:
This really is the only rom I can use without problems. I really wish it was more actively developed. If this rom had backlight notifications voodoo color and the newest gps tweaks that really do work, I wouldn't even be tempted to try another rom.

I can't use any i9000 roms. I lose signal a few times a day and every single night. It always takes a reboot to get it back. I do live in an odd area that has equal strength combination bands on both 1900 and 850. Which one is stronger changes room to room and block to block. The modems that work with the i9000 roms just can't handle it.
[Captivate Android Development] cumanzor:
Any words on how to flash only the kernel and modem?
[Captivate Android Development] Neowind:
haha, my alarm doesn't work too. I have to use another software like alarm+ or something like that. I'm reading around and flashing perception :D

just to test but i think i'll back to cog2.3b6 :D

Test

Tested beta 8 for a few days days experienced a few forced closes and wifi problem but nothing to significant but i have already flashed back to beta 6 no problems with that hopefully soon it will be perfected and come out of beta
[Captivate Android Development] dizx:
Hi All,

I've been running Axura 2.5.1 with no significant issues, but thought I'd come back in and run a pure Captivate ROM for a few days to compare.

From what I've read, just flash Cog2.3b8, figure out which modem works best for me, figure out which GPS settings work for me, and away I go, right?
[Captivate Android Development] tbong777:
Back to a stable Perception......finally. I liked the captivate ROM but Perception's ROM stuffing is far better.
[Captivate Android Development] rootnik:
Always works best with flash to stock, master clear, then flashing the rom. You can use the same update.zip you used with Axura to install clockwork recovery.

Don't expect much from the gps though. i9000 roms are king when it comes to the gps.

Things you can expect:

Better battery life

Better bluetooth

Worse GPS

Also, you can take the /system/framework/framework-res.apk file from your old zipped Axura rom and extract /res/anim from if you want to keep the Axura transition animations (do this before flashing). Once you extract the anim folder delete the same folder from the cognition rom zip and replace it with the one you took from the Axura rom. Don't try to replace the whole framework-res.apk file, just the animations. I thought about making a zip you can install with clockwork recovery to do this for you, but I'd have to get Adam's permission before posting it.

Part of the reason Axura felt so fast were the animations. You'll be surprised how fast Cognition feels with them (especially after using the spare parts app to speen up the transitions).
[Captivate Android Development] Delicate Donut:
Is this lockscreen the puzzle one? Cause I really miss that thing lol
[Captivate Android Development] dizx:
Yep, Always go back to stock and MC. I'm paranoid that way. :)

Thanks a bunch for your additional comments and tips.

This flash round will give me an excuse to work on my nv_data and unlock codes as well.
[Captivate Android Development] s44:
Pretty much. Others have discussed the flashing part. Looks like Da_G's thread may be the GPS fix of the moment.
[Captivate Android Development] wezli:
Overclocked?

Love the 2.3b8 ROM - stable, fast, and free of all the bloatware from AT&T. But... I'm getting about half of the battery life that I used to. I only make it maybe 8 hours before I have to recharge. Is this an OC'd ROM? Any ideas for extending battery life? I've already killed off all unnecessary tasks and dialed brightness down to lowest setting.

Cheers,

W
[Captivate Android Development] cumanzor:
Finally did a stock recovery and master wipe with odin. Installed b8 and signal seems to be better, although I haven't tried GPS yet.

One thing though. I'm hitting around 1600 with quadrant, but overall I.'m noticon some lag with some apps. Anyone else having this experience?
[Captivate Android Development] TAWoody:
You probably just need to calibrate your battery. I did for mine.

HOW TO: BATTERY Calibrate

1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%

2. Disconnect the phone from the charger, and power it off.

3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).

4. Disconnect the phone from the charger and power it on.

5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.

6. Disconnect the phone, power it on, and use it.

You should only need to use this sequence one time
[Captivate Android Development] loraque:
I tried 9.5 out, and immediately saw the same modem problems- Bluetooth refused to pair with my car, and incoming calls were not ringing the phone. I could have flashed JK3 which I had previously had decent performance from, but honestly I am fatigued from the modem flashing frenzy that i9000 seems to be. While I was out picking up Chili's curbside, restored back to Cog8 and problems go away so I don't have to keep explaining to the wife why my phone is only partially functional when I am supposed to be the geek of the house.

I wonder if it is area, signal strength or whatever it is that gets such varied results.
[Captivate Android Development] TexUs:
15 hours of very light use (a dozen or two texts, a phone call, some facebook surfing) today.

Down 30% battery life.

Got to say, DG... This is the best ROM on the market (Perception is good except for the stability problems).

Axura sucks a$$ when it came to battery life, I couldn't have made it on these 15 hours on Axura and I've still got 70% left on Cognition!
[Captivate Android Development] TexUs:
I'm actually having trouble seeing what advantage Perception is over Cognition???

I'm on Cog and don't miss anything on Perception.
[Captivate Android Development] kaczu:
I've used both. Percep is faster than Cog in most things. However, it comes at a cost. Bluetooth and stability for handling voice calls isn't as good. Overall it's kind of a wash depending on how you use your phone. Battery life used to be better than Cog. However, I flashed Cog b8 earlier. 9 hours so far and I'm at 85% with WiFi on. It is slower with minor stutter but if I make it 2 days on a single charge i might have to keep this for a while.
[Captivate Android Development] RDI:
Any ideas on why TitaniumBackup, all of sudden, will not see any apps? I tried reloading app.

Also, my 2 email accounts (not gmail) are gone.????

Running Cognition v2.3b8
[Captivate Android Development] Death_Keeper:
my cappy also suffers from this issue, cant seem to get it right.

i did what you described, it did show 100 after step 6, but 10 min later when i connected the phone to the computer it showed 97% :(

if i just charge it, than when it completed the charge i take it out - again 97 or 98...if i try again - 99...when i let the phone stay connected for the night, in the morning i get a real 100% reading that lasts. (the batt works fine for about 15 hours of moderate use - so this is not a batt issue).

i tried everything, wiping the stats, than calibrating. calibrating without stats wipe.

flashing at 100%... nothing worked...

what am i doing wrong?

im on the last cog rom and very happy with it...just this bug drives me crazy!

Hope someone can help...

Thank you DG, and everyone for your help!
