[Hero CDMA Q&A, Help & Troubleshooting] gTen:
Once 2.2 source hits there will be sense roms...which will be by end of the year most likely.

Yes they do..there just isn't a stable release yet...do't take things out of context...

Only 15 hours? I got over 24 hours on stock Epic..but then again as with all things it varies by usage...

True its not, but at the same time, stock Epic has less wrong with it as stock...aka we don't need custom roms to fix a lot of the issues because they work out of box...not saying there are no issues of course..That said it also has a HUGE i9000 community backing it which is bigger then the EVO one...

You can notice the difference..its not just the GPU...the 45nm cpu process adds a lot..not to mention hardware video decode via the ARM Neon.

Well I wouldn't say it adds nothing...just sprint removed a lot of the benefits it gives..its a very simple UI and very clean...some like it some hate it..but if sense is your hting a prot will be soon

The Epic will be getting a 2.2.1 update by the end of the year..which would make it ahead of updates then the EVO since it only has 2.2...lol...The Evo will not be getting Gignerbread officially for at least a few months...(if it ever will)..and please dont talk about HTC's track record (its horrible..even worse then smasungs ever been)...while samsung has been know for having shorter release cycles, HTC has also had a VERY terrible track record that only improved recently...I think samsung deserves at least a chance just like HTC has gotten..

This just means they arent confirming it or denying it...neither HTC or Motorola confirmed they are getting it either...overlal though chances are Samsung will release Gignerbread for the Epic..little reason why not..
[Hero CDMA Q&A, Help & Troubleshooting] stayclean:
Epic running better out of the box is more of an opinion than anything. Few people I know who opted for then over EVOs had to root on day one just to apply those lag fixes. Also, there is only a rough alpha of cm6 for just one of the galaxy s phones.
[Hero CDMA Q&A, Help & Troubleshooting] gTen:
Well.. everything subjectively is an opinion..that said I have yet to see one person deny that the Epic runs better stock...even EVO owners...

Lastly, are you sure you are talking about the Epic in specific and not other Galaxy S phones? The lagfix is almost useless on the epic as it doesn't need it..at best it offers 1% improvement on the Epic..at best..for the other Galaxy S phones it does offer a huge improvement.

Oh and there is an alpha for 3 phones..i9000, Vibrant and Epic...though not sure if vibrant is actual one or jsut a port of i9000
[Hero CDMA Q&A, Help & Troubleshooting] theimpaler747:

[Vibrant Q&A, Help & Troubleshooting] testomat:
Hello,

i'm newbie. Could someone tell me what the difference between ROM and Kernel and Mod means for a mobile phone like a vibrant?

Must the kernel fit to the rom ? Or could you use different kernel and rom versions?? "Mod" only applies to software like skin or theme ?

[Fascinate Android Development] geeknik:
This is an undervolt test version of my new StupidFast Kernel v1.2.3. This is a TEST release (NO VOODOO). This kernel aims to be fast, compatible, stable, and have good battery life. It is based on my StupidFast v1.0.36.

Changes since 1.2.2:
Fix for the 0.5-1.0 second pause/lag opening apps/drawer
Scheduling Tweaks
I/O Tweaks

Changes since 1.1.23:
Stock 1ghz @ 1225mV

Changes since 1.1.14:
Tweaked minfree settings
tweaked io scheduler
more compiler flags for cortex/hummingbird cpu
tweaked wifi scan interval to help with battery life

Changes since 1.0.36:
removed custom boot animation to trim size.
using kernel jhash3 instead of jhash2.
optimized compiler flags for the hummingbird cpu.
changed some kernel scheduling timings.
BLN disabled by default (configurable with [url=http://xdaforums.com/showthread.php?t=823922]this app[/url])

You will see that the custom boot animation was removed. It's okay. If you already have v1.0.36, 1.1.4 or 1.1.23 installed on your phone, the animation will stay. If you're new to my kernels with v1.2.3, your old boot animation will be there.

I'm not seeing any lag on the phone. Gallery opens pretty much instantly. Settings->Applications->Manage opens pretty much instantly. Launcher Pro+ pretty much instantly appears when the phone starts up.

Testers could NOT find any audio problems with this kernel using the media player in JT's Clean ROM. I've tested Youtube and Pandora and have had no audio issues. Also, we couldn't find any issues with USB mount/unmount, settings changes, etc.

As always, if you find a bug or what you think might be a bug, let me know. This is NOT the final stable release of the 1.2 kernel. :) Stay tuned to #samsung-fascinate on FreeNode or @geeknik on Twitter!

Download:

http://dl.dropbox.com/u/6088006/stupidfast-test-v1.2.3.zip

saps from #samsung-fascinate said that v1.0.36 was "far and away the fastest real world kernels I've ever seen, period"

If you like my kernel, show me some love. Donate today! :cool:

Thanks to saps, jt1134 my beta testers and the kind folks that donated cash to the cause! Keep fighting the good fight! :D
[Fascinate Android Development] themobijew:
sweet. dowlloading now. :)
[Fascinate Android Development] bL33d:
Downloading also. :)
[Fascinate Android Development] destroyerbmx:
I like your kernels, but I just noticed I am getting a super weird output in ADB when I try using that. I also have superdark ROM so it could be either one.

Ok, I just rebooted and checked again and all is running fine with 1.2.2 in recovery, but not in running android system, must mean its the rom.
[Fascinate Android Development] spyd3r05:
Downloading now.. went with full full wipe with jts clean, and still getting popping, on asop player, double twist, pandora
[Fascinate Android Development] mexiken:
Besides the battery life which is supposed to be increased, is there any other benefit to UV ???? Longer processor life, runs cooler, etc.

What are the drawbacks, if any ???? Does performance take a big hit, etc.

I'm asking more in general terms. Obviously I will observe first hand with this kernel, which I'm downloading now.
[Fascinate Android Development] destroyerbmx:
In theory, as I know computer not cell phone, UV will allow it to run cooler, which does mean last longer (but is that really a problem?) and use less juice while still being as fast as before. If it runs stable you will not see a performance hit and it will better with the battery. It will just freeze your phone if its too low and requires more juice, really no harm can be done, overvolting is more dangerous as that burns up cpus, but you overvolt to make the higher frequency stable. Simple overclocking principals apply, you want the lowest voltage for your cpu frequency.
[Fascinate Android Development] destroyerbmx:
are you upping the CPU to 200mhz to run those? I am doing that and its just fine, although I never had a popping problem at 100mhz either. I just set the min to 200 because that cleans up a little bit of the lag too.

Possibly related, every once and a while my phone will just decide to press a soft key on its own, what is that? (that causes a slight skip in the music when I am playing it)
[Fascinate Android Development] spyd3r05:
see if listening to it while hooked to power recreates the problem... i noticed for me atleast its only when plugged in...
[Fascinate Android Development] destroyerbmx:
I have it up to USB and its not skipping or popping right now, I am also using mixzing
[Fascinate Android Development] abowlofsoda:
v1.2.2 is the least fastest of all the geeknik kernels for me. There is 1 almost 2 second pause loading and exiting apps unless it was already in memory.

Still faster then everyone elses kernel. And so far battery life looks to be way better on this one but I haven't had it long enough to say for sure.

Nothing has changed on my audio popping issues so I am still using SetCPU at 200min still. I am short 6 hours of battery life like this by my best guestimate... which isn't a big concern for me- just reporting for those who need to make it thru a day without a charger nearby.

Never had any FC's with USB.

Touchwiz/JT's Super Clean ROM

And a thank you to geeknik for all your efforts! love how your pumping these out!
[Fascinate Android Development] problem0atique:
Kernal runs great! No unwanted sounds from the stock music player in jt's rom. USB works just fine. Thanks for your hard work!
[Fascinate Android Development] spyd3r05:
are you using setcpu? if so that helped me fix it bumping min to 200... any one else having the problem might try that...
[Fascinate Android Development] iceman1183:
Interestingly enough, this kernel does seem a touch slower than the 1.2.23 regular voltage kernel. Hangs just the slightest bit when firing up and exiting dolphin browser and xda app. Still, appears to be MUCH better with battery life, as the previous geeknik kernels were ravaging my battery.

Definite progress but not quite perfect imho. Still thanks for all your work geeknik, you're killing it with these.

Also fyi, running custom blackhole, with sns and lp
[Fascinate Android Development] mindtrip1016:
This kernel is running fairly smooth, like the other 2. I can deal with the extra 0.5 second delay when first opening an app, as long as BLN is optional and battery life is extended. Thank you very much for taking the time to come up with these kernels for us. Other kernel providers tend to make their products less accessible for us XDA users, but you take the stress out of the search. Thank you again.
[Fascinate Android Development] zachsx:
Can someone explain how to get bln. I saw a post about it but can't find it or I'm over looking it like an idiot
[Fascinate Android Development] iceman1183:
Re-read the first post of this thread, there's a link to how to enable/disable bln
[Fascinate Android Development] saps:
The uv kernel is a winner of course. I test these kernels for geeknik before he throws them up for the masses. Not just running quadrant [although I do that too] but going thru the real phone stuff itself. The manage applications load, replacing new dock shortcuts, gallery, apps and stuff everything we actually want to see improve with.

I for one never had battery issues with previous stupidfast kernels but I know some did, same this music crackling. It seems to me most of you that do are either running blackhold or deodexed rom though and quite humbly I'd look their for your culprit moreso than the kernel. If there was a music skipping issue from the kernel itself it would manifest itself across the boards but it doesnt.

Anyway, battery life is going to be stellar trust me, under light-moderate use Im only using like 2% per hour here swyping 8-10 texts per hour here, very good indeed
[Fascinate Android Development] abowlofsoda:
Hey Saps- I see ya on all the forums and your contributions have really helped me out...

That being said I keep seeing an overlook of real world usage in these testings. Can you guys test beyond stock apps? I mean checking stock should be the first thing you do obviously but how many people use the stock music player or the stock browser, etc? I am betting most the people that have the knowledge enough to test these kernels and ROMs aren't using stock functionality and apps.

Please test this kernel with the PowerAMP or Music PlayerPro music apps before writing off the issue.

Use Dolphin to check the internet, etc. Use K-9 to check email, etc.. ya know- use the popular apps during testing also if you could?

Audio cracking, FC's with the USB settings, and I even heard mention of live wallpapers having issues. These reports coming from 3 reported different ROMs.

How are you missing this?

I myself have had great success with battery life on the Stupid Fast kernels. Better then stock kernel for sure. But I've been having to run my battery faster by using my workaround to avoid the music crackling.

JT's Super Clean ROM using TouchWiz

Just suggestions so we can all get on the same page and enjoy these badass mods.

P.S. What ROM are you using during testing of this kernel? I'll gladly switch to fix the issues
[Fascinate Android Development] sic4672:
I would definately clear your battery stats.
[Fascinate Android Development] mamoru16:
I kind of liked my stock bootup animation, but it got removed once I installed the kernel. How do I get it back?

Other than that, kernel working great so far. I'll report later on stats after some use.
[Fascinate Android Development] DroiDAddicT14:
My quadrant score was 969....is that supposed to be accurate w/ this kernel?
[Fascinate Android Development] mindtrip1016:
I agree to extent. With the kernels installed, the device will reboot fine, which at some point during that time I would assume the device is "off". But when turned all the way off, "power off button" it will not completely cycle. I was only trying to relay my experience exactly as it occurred, in hopes of finding a solution or atleast others with the same issue.
[Fascinate Android Development] HybridByNature:
On my first try, my phone hung on the Clockwork Recovery screen at the "Finding Update Package" step. I waited 10 minutes and then pulled the battery. KEEP IN MIND: you are not supposed to do this at any other portion of a kernel flash. Anyways, my device restarted and I tried the kernel.zip again and it went through without a hitch. Took about 45 seconds for the whole thing to complete.

So far my Fascinate is running wonderfully. I've only had StupidFast in place for a little while but I definitely notice an improvement. My main concern was the keyboard / typing / texting lag I was experiencing but that is totally gone. It pops between landscape and portrait superbly as well. I am waiting to see if these improvement are truly long term or just a band-aid.

Apps dispearing

When switching from Dirrk's undervolt 1.2ghz to this kernel, upon reboot, my wallpaper changes back to one that it was like a week ago. Also, maps is no longer installed, as well as some other apps.

Flashing back to Dirrk's kernel brings back all these apps and my correct wallpaper. What on earth is going on with this?:confused:
[Fascinate Android Development] itznfb:
I waited until it died. Charged it while it was off and then reset battery stats. I'll report back with battery life.

[Fascinate Android Development] iTz Nicholas72:
I did the reboot after unplugging trick and the battery life issue was fixed for me.

8 hours at school with 100+ texts sent/received, at least 30 min on internet, a few pictures, and just a few minutes of Angry Birds.

Got in my car to drive home at plugged it into the charger and had 75% battery left.

Much better than before and ~10% more than stock.

ROM: Blackhole 1.3

Kernel: StupidFast 1.2.3

How long was it plugged into the charger before you rebooted? I plugged in phone for a few minutes, unplugged it and rebooted phone. When I go into Battery history it still shows running at 100%....

edit... Didn't give it enough time to go to sleep. Now showing 86%.....

hopefully this will give me a few more hours of juice.....

[Fascinate Android Development] itznfb:
So after wiping the battery stats it seems to be reporting battery accurately and seems to be a decent increase in battery life. Though this kernal has a decent amount of lag for me compared to the stable release, and the audio bugs are just killing me. My Fascinate is my primary mp3 device. I wish I knew something about code so I could help pinpoint the issue. I'll use jt's kernal for primary but I'll keep testing these as they come out. Thanks again for the great work.
[Fascinate Android Development] PhoenixPath:
Getting the gos issue here as well, just hadn't noticed it until I saw it reported here.

Stupidfast 1.2.3, blackish theme, and blackhole rom. (should be latest version of all.)

Sent from my stupidfast blackish hole...
[Fascinate Android Development] zeiroe:
Thought I'd post my results here as well. First, let me say that this is a really good kernel to use on a daily basis. My OS load is stock with all samsung apps still intact. I did however remove all bloat, bing and verizon crapware.

After I installed the 1.2.3 kernel, I did a factory reset from within the system options. I wanted to start fresh as I noticed clockwork and the stock recoveries wipe options do not completely wipe everything needed ie: dbdata.

The biggest benefit I noticed immediately is speed. Second was GPS. Side by side to another fascinate with a stock kernel, StupidFast gets a lock in 1-2 seconds. Even after a syncronized reboot, then immediate opening of GPS status, the GPS lock with the StupidFast Kernel is ... Stupid Fast =D

Bad thing I noticed is that I cannot clear battery stats. The clockwork recovery option does not return a confirmation message when the batterystats file is deleted. Manually checked the file and it is indeed still the original file.

Second bad thing is dalvik cache. I don't know about anyone else but if I clear my dalvik cache, its dead. No matter how long I let it sit to recreate the cache, it just sits there on a black screen. Logcat shows no activity

Other than the problems I've experienced, his kernel is great and will continue to be my daily driver. Can't wait for updates =D
[Fascinate Android Development] CHANGiism:
I'm a newbie when it comes to flashing and stuff so bear with me. I just noticed that I have update.zip file on my sdcard after flashing this kernel and I'm wondering what it is. Is it safe to remove and what does it do? Thanks.
[Fascinate Android Development] em.Tea:
personally i find this kernel great and fast. the only thing is that i get crappy battery life with it. it dies twice as bad as a different kernel im using. and this is comparing the StupidFast kernel(barely using the phone) to JT's test 11/16 UV kernel (and using the phone, ie games, internets, texting)

is there something im doing wrong?
[Fascinate Android Development] mexiken:
Try charging the phone, turn off, then boot back into recovery, and wipe battery stats. That seemed to get more accurate battery life for me.

Also, people have reported that the phone/kernel combo has a bug where when plugged in to charge, the phone does not go to sleep anymore once unplugged. At this time, the only known workaround is to do a soft reset AFTER you unplug the phone.

Hope this helps.
[Fascinate Android Development] fifreak:
I can confirm this solved all my battery issues. Stock ROM + this kernel.
[Fascinate Android Development] androidman78:
Do not remove that it is the update you need to run at first recovery screen to gain access to the clockwork recovery never remove or put in folder someplace as it needs to be on the root >>> /SD/UPDATE.ZIP/........To have ClockworkMod Recovey.
[Fascinate Android Development] mattstakilla:
I would like to know this also. My g1 would say the name in kernel and rom. Does the dev need to add this? Or is the fascinate not able to show it?
[Fascinate Android Development] crispybacon:
If you use SetCPU go into info and all the kernel info is there.
[Fascinate Android Development] mattstakilla:
Loving this kernel. Went to voodoo then returned too stock kernel. Tried some other kernels and this is by far the best.

Battery went to being around 30 percent at the end if the day. Its now 10 pm and battery is at 68 while writing this message. I've used games, gps, browser and camera throughout the day.and still at 68. Loving this
[Fascinate Android Development] dashultz:
Well I want to start off by saying this Kernel is amazing and mad props to geeknik for his hard work.

Background on my set up - running a custom themed, base rom and was running Voodoo for a while...I somehow felt that after three weeks of voodoo I felt it was actually slower than stock so I uninstalled and figured out it was only slightly faster and my memory is bad.

I picked out this kernel and loaded version v1.2.3 without problems - it ran very well and was superfast. I am not running setCPU and did not experience any application problems or sound issues. I did however have "battery problems". I installed the Kernel on Friday and after resetting battery stats Today was my best test to verify my concerns from Saturday - by 5pm today after some browsing, tweetdecking and texting (no calls) my battery was still draining as fast as ever (46%).

Saturday my batter died very quickly after charging the entire night - I tried the restarting even to see if that slowed the drain but seem to do nothing.

I decided to flash to version 1.0.36 (I noticed 1.5 is available if you are running DJ05 - but not published so those who are not faint of heart and know where to go you can let me know how that update is) which is running great and it seems my batter drain has really slowed drastically (25 minute phone call, pictures taken, couple more texts, little browsing - battery went from 34 to18 in just 3 hours).

So - I guess the later version are out until I update to DJ01...Mad props to Geeknik as this kernel is lightening fast.

[Fascinate Android Development] godihatework:
I love these kernels. I have experienced a live wallpaper force close issue when turning the screen on after it auto shuts off. The usb issue is part of the blackhole rom a the service is not included. As for the sound issues I have not come across them, however I rarely use the phone for music, so meh...
[Fascinate Android Development] starscream84:
Godihatework too =) ............. oh yeah, and this kernel is awesome =)

Thanks geeknik for your hard work and thanks saps for guinea pigging for us =)
[Fascinate Android Development] tlogank:
To those complaining about the USB Settings issue, the Blackhole ROM creator has openly admitted he is responsible for that. He said he removed the option, but will add it later. See his post here. Just wanted to say that so we could stop blaming this kernel. Thanks.
[Fascinate Android Development] spyd3r05:
Those still having audio problem download setcpu.. and boost your min to 200 and you should be good to go...
[Fascinate Android Development] neyenlives:
That makes no sense. Without setcpu the cpu runs at 1ghz all the time. So you think underclocking to 200mhz fixes an audio pop issue?
[Fascinate Android Development] abowlofsoda:
It does make sense- its not underclocking... your setting the minimum (min) to 200. The maximum is still untouched and running at 1000. If the cpu runs to slow (100) it skips. Or so thats how I understand it.

And FWIW, it works on my phone like a charm. But be aware it eats more battery. You can just shortcut SetCPU to the home screen and set it to 200 right before playback of music in affected apps then return to 100 afterwards to save some battery life. Its a good workaround so we can continue using this badass kernel AND music players like PowerAMP.

Have you guys tried PowerAMP? Its the best music player I've tried and I have all of em. Its has features the other ones never even thought of yet.
[Fascinate Android Development] emarx429:
Seems good so far... got a 920 on quadrant, which is really only important to me cause some of the older undervolts froze on my phone when running quadrant testing... i actually think that's the best results i've gotten on a non-voodoo kernal...
