Whether to swap or not is an age-old debate - no doubt about it. The XDA post that I referenced talks about some of the pros and cons.

Nine months ago, I came from a Samsung Intercept where (for me) running swap was a necessity for that 256MB RAM. There were pros and cons for that based upon the 800MHz processor and no GPU.

However, I believe the proof is in the pudding and right now, my Exhibit seems faster using swap on CM9 than it has ever been. The problem is that there is no benchmarking the performance via an app, as it only shows when switching from/to another app/screen, etc.. So, it is a total experience mod that should help negate the lag - especially for people who multi-task a lot.

I'm still experimenting and I will do my own benchmarks with and without. I just thought I'd throw this post out here.

Regarding the wear on the SD card. Yes, it will cause excess wear - but only in the place that you put the partition (i.e. the last 256-512MB of the card). If it goes blah.... then just create a new partition or turn off swapping... Don't use a swap file.
[Samsung Galaxy Exhibit 4G] a0b1c2:
Yah, that's the problem .. one of the jobs I do is run benchmarks and saying something "seems" faster .. well, ... you know! :) :) :) ... it's not very scientific.

I'm not trying to dispute that your effort isn't valid ... what would be cool is once you have it dialed in, to put up a youtube video showing a before and after. Or something which you believe showcases your effort.

Cheers!

Some CM9 issues.

Google Navigation and Waze audio is lower than other audio.

Waze has locked up a few times.

Google Now is still pretty sluggish.

The phone is sucking the battery juice pretty quick too.

I'm sorry if some of these issues were already posted. Otherwise I love CM9 but also may go back to Peach Sunrise for a bit until CM9 matures a bit more. I really don't want too but I think giving CM9 a bit more time to mature is in order.

My favorite feature of CM9 or Android 4.0 is how the speech to text will show you the text as you speak.

I think I will look into dual booting or something.

I hope my bug reports help. ;)
[Samsung Galaxy Exhibit 4G] friedCELLS:
I see some people having issues that I think may just simply be due to not wiping well. Even if it's a small update, I've always preferred a full wipe b4 installing. I wipe dalvik & cache like twice. ROM wipe twice, & even factory reset once. I make sure it's clean. I've never had most issues that people report. I can set my phone up in about half an hour though. I simply make sure titanium automatically backs up to the external SD. I also set up my pictures to automatically store on external SD. These steps save time in copying folders as the resets wipe all data on internal but leave external safe. So before wiping, all I have to do is use SMS backup app to backup my texts as titanium fails at this for me, and then copy that folder, data folder, & any other necessary folders to the external SD. Then wipe, install new ROM, install titanium & es file explorer, move folders back, batch restore in titanium missing apps without data, then go back & restore data only where needed, use SMS backup to restore texts, change the setting that I like. Done. Easy. Phone works great every time. Oh, I also use nova launcher, & backup the configuration before wiping. Then after moving that folder back in place, simply restore configuration, & no need to put back 1 app at a time. If you're having issues that others don't have, try a better wipe. And hopefully you're not restoring apps & data that were saved on a gingerbread ROM. That can cause issues. Only issue for me is vanishing text in emails, browser, etc. Otherwise, great battery life, great speed. Near perfect. But vanishing text is noted in OP, so no need to report it.

[Q] PC-SD Help

I was wonder if the CM9 thread could help me. I created the update for the KEMIUI 2.8.10 based off of this updated rom. My phone recognizes the external sd and reads all the data. When I plug it in it show the internal SD. How do I get it to pop up the external instead on the computer?
[Samsung Galaxy Exhibit 4G] dennis96411:
Hm, I guess I'll have to wipe again. Ah, the joy of restoring all my apps and redoing my homescreens again and again :P
[Samsung Galaxy Exhibit 4G] SurgeRush:
These are the only changes in 04 correct?
[Samsung Galaxy Exhibit 4G] jocala:
Try just a dalvik and cache wipe. See if that works.
[Samsung Galaxy Exhibit 4G] braski:
Hey jocala can confirm the brightness and lockscreen also battery is not charging for me
[Samsung Galaxy Exhibit 4G] jocala:
I'm sorry you are having problems. So far, I can't replicate them. Here, installing after a full wipe, adjusting brightness works from both the status line and settings. The display blanks when I press power and does not flash. It also blanks after a set delay period. The display rotates as it did in 03. Turn on autorotation in Settings->Launcher->General. And the battery is charging as I type...
[Samsung Galaxy Exhibit 4G] danny8:
CORRECTION: Backlight turns off after short delay. Still no brightness adj. Anyone else have haptic fb come and go at random?

Will try 2-cache wipe. Second shot at gapps (re-copied) worked. Gonna format/wipe some things after playing with CM_wip (=work-in-progress) a while.

Weird: XDA is not in the Play Store. Had to get my Ti backup.

Whatever happens, thanks dude.

The .nomedia file has been an option all along, I just discovered it.
[Samsung Galaxy Exhibit 4G] braski:
maybe it was me idk plugged my phone in at 40 percent, went did some things came back it was at 20. Did a restore of .03 it's charging now when fully charged I'll try again :)
[Samsung Galaxy Exhibit 4G] richardlibeau:
thanks i was wondering that
[Samsung Galaxy Exhibit 4G] danny8:
Maybe something that should be looked at

Jocala, I could be barking up the wrong tree here. Something appears to be amiss with the CM9 file system. I noticed this before, but I didn't make too much of it at the time.

I decided I needed to reformat my external SD card. I could do this on my PC but I figured it'd be better to use my phone to format it. I went to the storage devices section of my system settings. There I see an entry called "SD Card". It shows an eight gigabyte volume with a display of in-use / not-in-use. The amount "not in use" is incorrect. I didn't really pay much heed to that. I went ahead and formatted the card. EDIT: The "not in use" amount might be correct, according to gparted. I see a lot of the .tar files have a size of zero bytes when they should be ≈50-120 MB. Regardless, the wrong device was formatted. Maybe I'm confused by the settings panel. I'll be looking at it again. There should be a way to format the external SD card using the GUI, or so I hope. It seems more likely to me that someone would want to format the external card and leave the internal card alone. So they should make it easy to do the more likely thing. WTH do I know, anyway.[END EDIT]

What results is my internal SD Card is formatted. My external SD Card was left untouched. I was using the "eight gigabytes" to assume I was formatting the correct device. This was a bad assumption. No harm is done, but it says to me either something is set up wrong on my device, OR the OS has a device conflation of some sort.

Dumb/rude question, but you have an external SD card installed in your test device, right?

==

Perhaps unrelated: I read the back-and-forth about CWM wrongly labeling the menu items pertaining to the external sdcard. I never noticed this issue even though I went looking for it. I was sort of paranoid and even asked you about it once. I reinstalled CWM regardless. Again, this might be a red herring. So far, I've not had a problem using CWM (other than my own dumbness).

Tonight all CWM backups on my external card fail on the checksum step. ALL THAT CAN BE TOTALLY MY OWN FAULT, I simply don't know. OR, the card might have gone bad.

Anyway, I've got clockwordmod copies on my PC. Going to reformat my card in PC. Then I'll try to use a PC backup and roll back my phone via CWM. My phone still boots to both OS and CWM recovery mode. Yay.

Thanks for listening. :p
[Samsung Galaxy Exhibit 4G] stab244:
Can I update to 04 from 03?

Also everyone I try to download it gives me an invalid token error.
[Samsung Galaxy Exhibit 4G] jocala:
As in applying a diff to update in place? No. I just downloaded 04 w/o problems.
[Samsung Galaxy Exhibit 4G] stab244:
Like updating from release 3 to release 4 of this ROM.

And hmm guess I'll try to redownload later.

Edit: I clicked on your name and the file isn't listed there. Weird.
[Samsung Galaxy Exhibit 4G] dennis96411:
Do you rename your backups? Like do you rename the folders that backups are made in? That causes MD5 checksum fail.
[Samsung Galaxy Exhibit 4G] danny8:
Thanks man. YES! I was wondering about that myself. I dropped two digits and a period from the end. Doh, I'll never get them back.

Irrespective of that blunder, my backups are clearly damaged. Based on the file sizes. Also, my last nandroid created tonight (never renamed) was a mere 13 MB. That ain't right.

But it's good to know about that. I won't be renaming them in the future.
[Samsung Galaxy Exhibit 4G] jocala:
Erase SD Card via storage settings formats the internal sd, not the removable. Offhand, I don't see a setting to erase emmc. You can reformat emmc in CWM. No fs problems here.
[Samsung Galaxy Exhibit 4G] SurgeRush:
Ok, so a problem I've been having since I got the phone is when I plug anything into the headphone jack, the volume on the phone can't go above around 75% without pausing my music and lowering my volume. I usually switch roms before I go out, so I haven't had the phone playing in my car on the rom since 02 when you needed to use the widget to get things to play through the jack. Left the rom on today, plugged my phone into the car, and now I'm having the volume problem again. Although it doesn't lower my volume, if the volume is too high on the phone it keeps pausing my music. Can't stand this volume thing, it's been driving me nuts since the beginning.
[Samsung Galaxy Exhibit 4G] jocala:
Geez, this is really turning into *****, piss and moan night. Thanks folks :)

AFAIK, the volume reduction issue was a Samsung ROM proprietary "safety measure," not a cyanogenmod problem. I just plugged in my earbuds and blasted out Blue Oyster Cult's Godzilla at full volume. No skips, no pauses, no drops in volume.
[Samsung Galaxy Exhibit 4G] SurgeRush:
Not trying to complain, simply letting you know something I ran into... Thought that was the point in betas.
[Samsung Galaxy Exhibit 4G] jocala:
My snark was not directed at you personally, ended with a :) and I answered your question with the best info I have.

[Samsung Galaxy Exhibit 4G] Octanee:
im having troubles with this latest build 0814, my screen seems slow, if i scroll down ONCE, its nice and fast, i release, and try again and its either a:retarded and slow responding or b: does not respond and i take my finger and swipe a few times... orrr it will think i selected something when i didnt, i did a full rom wipe of course...

also using it a bit more, its feeling sluggish, fast.....
[Samsung Galaxy Exhibit 4G] afwolfpacked:
For the slow screen problems have you done any memory management tweaks. The performance tab allows for some minor ones and I personally use V6 rc10 in conjunction. There is another memory manager that is an app in the market that is easy interface to work with. I can't remember the name but it has been mentioned many times above this post.
[Samsung Galaxy Exhibit 4G] ETFoneHome:
I noticed my recent app reviews on Google Play using cm9 does not display the Samsung Exhibit II device under my name on the reviews.

Anyone else noticed the same?
[Samsung Galaxy Exhibit 4G] lolitsjae:
Hm...has anyone thought about or already have flashed this? I wonder ...
[Samsung Galaxy Exhibit 4G] 954wrecker:
I flashed and played with it for a few hours its not bad.
[Samsung Galaxy Exhibit 4G] lolitsjae:
agreed, it's not terrible, actually it's a really big leap from early Kemikal's project. But it does have a tendency to not recognize the music, which are kept in my sd card.
[Samsung Galaxy Exhibit 4G] mrken:
Thank you Jocala for the recent ROMs! The camera was the only problem holding me back from using your CM9 ROM permanently.

I notice that the loudspeaker volume on CM9 is not as loud as the stock Bell ROM, using the loudest DSP Manager or Volume+ settings. The difference was significant when I compared two T679s side by side, with the stock Bell ROM being louder than the CM9 ROM. (Both T679s have similar volumes using the same ROM.)

Do you know why the loudspeaker volume would be softer on CM9?

Thanks again!

P.S. I upgraded from an LG P500 which can easily rupture any nearby eardrums.

[Samsung Galaxy Exhibit 4G] jrleathers:
Im using all performance settings on cm9 simultaneously with good results. I'm not using v6 yet. Tell you the truth I don't even know the best way to use v6 as I've only used it once on rebwlrom because it came with the rom. I've read the v6 thread but still confused which method to use for çm9.
[Samsung Galaxy Exhibit 4G] ArtfulDodger:
Save yourself the trouble. I tried it and ended up with force close issues. That was with letting it set everything automatically. The "unsupercharge" didn't work and I had to restore from nandroid. Maybe there was something I could have done differently, IDK.

Try Auto Killer from Google Play. I have the paid version and after experimenting I'm using the aggressive setting. Other tweaks are available in the app also. That coupled with Rom Toolbox Pro for tweaking CPU makes a good combo IMO. Everyone here has a different take on this but this is what has worked for me. BTW Rom Toolbox has a memory tweaking option but I like the extras Auto Killer adds.
[Samsung Galaxy Exhibit 4G] strtkempo:
Do not use V6 unless you have read the entire V6 op. This changes the way your phone operates and handles itself. It can break your rom. If you know how to use it, it is very beneficial. I did have some fc issues but fix permissions usually solves this issue.
[Samsung Galaxy Exhibit 4G] T679noob:
These options are good for memory management. I swear by the option I have checked:
[Samsung Galaxy Exhibit 4G] jrleathers:
I've read it, but confuses me a little on the correct way to use it so I've stayed away from it for now.
[Samsung Galaxy Exhibit 4G] congee:
I've got the same problem too. After I open the email, the text appears and then it disappears a second or two later. I did a cache flush and data delete which solved the issue for about an hour, but now it is back.
[Samsung Galaxy Exhibit 4G] a0b1c2:
Hi,

I had encountered the above issue yesterday. When I killed gmail (I have my Back button configured to kill an app) and started gmail, the problem went away. I believe I had also tried deleting and re-downloading gmail from the App Store first.

[Samsung Galaxy Exhibit 4G] Seminoles:
Change the two animation scales to off makes the ROM a lot more responsive someone said use spare parts a app on play store I was trying to find out how to use the spare parts built into the ROM and the only settings you could change where the ones in here maybe this is the ROM spare parts.
[Samsung Galaxy Exhibit 4G] jocala:
No luck here with that, sorry.

That's a great looking build though. I can't imagine there would be any objection if you forked it into your own project, since the original developer has moved on to another device and the project is moribund. You've already taken it quite a bit farther it seems, at least with my limited amount of testing. I hope you open a thread and invite people in!

Haha xda, the poor little device w/o a forum has active development for stock, cm9, aokp, cm7 and perhaps miui. :)
[Samsung Galaxy Exhibit 4G] congee:
The first time it happened, I restarted my phone. But then it came back. Definitely something funky going on.
[Samsung Galaxy Exhibit 4G] shakatu:
I can confirm that disabling v6 and setting all the CM9 performance tweaks makes this rom FLY!
[Samsung Galaxy Exhibit 4G] a0b1c2:
Hi,

Which CM9 performance tweaks did you set and what values?

Thanks a lot!

[Samsung Galaxy Exhibit 4G] tom_yellowblue:
I have a possible clue for the disappearing gmail test. Or maybe it's just the equivalent of booting into recovery and clearing the cache.

I found that these steps temporarily fix the problem just like clearing the cache in recovery.

1. Close the gmail app. I long-press on the home button and then swipe the gmail app away.

2. Change the extension of the gmail apk to something else. I used ES File Explorer with the root system writeable.

3. Change the name of the gmail extension back to .apk.

4. Open gmail, it works again. It doesn't need to re-sync.

Maybe just killing gmail and restarting it would work as another person posted. I think I tried it and it didn't work, but I'm not positive. I'll try it next time.

I don't know much about Android, but maybe as a temporary workaround we could write a script to do this.

su
kill -9 <gmail app>
cd /system/app
mv com.google.android.gm-1.apk com.google.android.gm-1.abc
mv com.google.android.gm-1.abc com.google.android.gm-1.apk

WiFi calling

The WiFi calling works great in this latest build the only thing is turning on after a reboot I may be a little off base in has been a long time since I dabbled in Linux but is there a start up folder or something like the one Windows uses if not how do you tell Android what to start on boot might be there is a switch that has to be added like ( libkineto.so -a ) to activate on boot.

:fingers-crossed:
[Samsung Galaxy Exhibit 4G] shakatu:
Under processor set CPU governor to "Interactive" and "Set on boot."

Under memory set zRam to 18%, purging of assets on, kernel samepage merging on.

That's really all I did. Before simple things as opening and closing the notification tray would stutter, now I can wiggle it back and forth smoothly. Also, many apps seem to open quicker, such as Dolphin Browser opening in 1 second. I should also state that I INITIALLY had the Google Now Gapps package installed with the 8-12 build, but after updating to 8-14 it was removed and I never reinstalled it. With Google Now people have reported the phone is slower. (GNow wasn't made for ICS anyways!)

On a different note, I had 75% battery left last night before going to bed, but I still charged it back up overnight just in case it died today. My experience has been opposite where CM9 is BETTER with battery than Peach Sunrise. I keep WiFi and GPS on all day, but have told WiFi to sleep when not plugged in, so that may be the big difference for me. Also, I disabled WiFi calling from loading at boot using Rom Toolbox, and I found that one change has improved battery life significantly. WiFi calling seems to be constantly running even when there is no WiFi connection, causing the battery to drop a % every few minutes.
[Samsung Galaxy Exhibit 4G] jocala:
Autostart (no root) works for Wifi-Calling app. Just tested it...
[Samsung Galaxy Exhibit 4G] mayateca:
Someone asked a question about speaker volume. I too agree that the CM9 speaker is quite lower than stock. Any tweaks to boost it? Already have it set to Max. Maybe an outside app? Also, someone asked if you have to do a romwipe to install Google apps lite over Google now; I want to ditch Google now too as its too slow and I prefer regular Google voice search. So, can I just flash the lite zip from recovery or do I have to start from scratch?
[Samsung Galaxy Exhibit 4G] jocala:
Yes, wipe & re-install.

[Samsung Galaxy Exhibit 4G] elmerohueso:
I just flashed CM9 (I've been on Peach Sunrise but wanted to check out the advancements in CM9). Biggest problem is it won't mount the internal /sdcard partition. If I go into settings and manually tell it to mount, it seems to try it (and flashes up the storage chart for a second) but immediately unmounts it. Any ideas?

BTW - Yes, I did a full ROMwipe first.

Edit - Got it working. Freed up some space on the internal /sdcard, now it mounts fine.
[Samsung Galaxy Exhibit 4G] tom_yellowblue:
My gmail text disappeared yet again and killing it worked for me too. I exited gmail, held down the home key, then swiped away gmail. When I started it up again it was fine.

Is it possible to get just the gmail app from the non- Google Now apps and replace the one I have? Has anyone seen the disappearing text with the google lite apps?
[Samsung Galaxy Exhibit 4G] interessant:
Just a reminder for anyone using camera more often. Please change to SD card storage because I've wiped out my camera folder twice already. :)

[Samsung Galaxy Exhibit 4G] jocala:
The gapps "lite" link does not contain gmail or maps. It's simply a framework that allows you to install those Google apps from Google Play. If you've installed gapps.now all you are doing is installing the framework with those apps added in as a convenience: gmail/maps/now. If you'd rather install them yourself, just install regular gapps and seek out the other apps from elsewhere. Gmail and maps current versions are always available from the Google Play store.

This has nothing to do with the disappearing text issue for gmail (which also affects Facebook IIRC.) The disappearing text issue is just another cross we must bear.
[Samsung Galaxy Exhibit 4G] a0b1c2:
FWIW, it happened again to me this evening. I back-kill'd gmail and clicked on it and voila! the problem is resolved (until next time. :) I hope the work-around works for other people.

ps: And ... I'm "this" close to deleting the RebelROM backup ... :) :) :)
[Samsung Galaxy Exhibit 4G] ArtfulDodger:
I have no idea why this is such an issue. I just wipe the cache as instructed and the problem never happens after that. Every new build that's installed this must be done each time and it only takes a few seconds guys.

You know the ROM is near completion when this is the type of stuff people are down to complaining about!
[Samsung Galaxy Exhibit 4G] tom_yellowblue:
Thanks for explanation, I didn't realize gapps lite was only a framework. I understand it better now.

---------- Post added at 07:29 PM ---------- Previous post was at 07:21 PM ----------

I'm glad it works for you, but for some of us it's not a permanent fix. I've wiped gmail's cache and its data. I've rebooted into recovery and wiped the cache there (several times). I've wiped the dalvik cache for good measure. Still the problem keeps coming back, 2-3 times a day for me.

I'm not complaining, I'm thankful for all the hard work put in by the devs. I'm just trying to find a solution.
[Samsung Galaxy Exhibit 4G] danny8:
In defense of folks with the disappearing text problem, it seems the problem does not always yield to quick fixes. And it's a really vexing problem when it happens.

I haven't had it in quite a while, but I've had it several times. I was tearing my hair out trying to fix it. At times I just ignored it, using my comp for email, seeing as I had other things to test with the ROM.
