SmartassV2 Hovers at 600MHz (as in will not go lower than) with the screen on but quickly scales up if something more is needed. Seems to spend less time at higher frequencies with the screen on and not doing anything than other governors.

Ondemand almost ignores everything between 200MHz and 1200MHz, quickly scales up at the drop of a hat and is also very smooth because of this. Seems to not use 100MHz when the screen is on at all.

InteractiveX seems much like Ondemand except it will actually use the 100MHz step with the screen on but it also seems to clock less time at 1200MHz than Ondemand when not doing anything.

Conservative stays at the lowest possible frequency it can unless the CPU load gets high enough for long enough then it scales up to the next step. For scaling down CPU load has to be below a certain threshold before it slowly moves back down. Might be worth it if you needed to get every last drop out of the battery but I found it very annoying to use as it can take a good third to half a second to scale up to a usable frequency leading to very laggy scrolling until it steps up.

All of them seem to sleep well with the screen off.

Tested with my phone set 100MHz min and 1200MHz max with the 900MHz and 1100MHz steps disabled and using the SIO Scheduler.

Overall SmartassV2 kinda acts like Conservative with very low threshold times and a high minimum frequency with the screen on to keep it smooth and InteractiveX seems to be an improved Ondemand from what I'm seeing. Its hard to say what one of the two would be better for battery life without further testing but I think this might vary greatly with usage patterns so I say test both and use the one you like.

Merry Xmas everyone. Of note : benchmarking a respectable if not slightly sluggish 1675 with about 60 apps on board and conservative color settings in Voodoo. I then bumped up the max voltage to 1200 in Voltage Control and touched no other settings and the phone is snappy and benchmarks around 2300 which I believe is where the phone should operate. It just feels right. Thank you Sensei for the wonderful rom.

Here is a back up of the default gallery(un zip into your titanium back up folder, and use titanium to install). I also like the stock gallery better than quick pic.
[Epic 4G Android Development] Devtodi:
Why do you like it better?
[Epic 4G Android Development] unoriginal:
Thanks for fixing the download issue. I was finally able to grab a copy of the ROM, now to test it out.
[Epic 4G Android Development] Devtodi:
Anyone going to try Shadow kernel 1.0.4?
[Epic 4G Android Development] TexasAggie97:
Wow, that's a lot of data to process but VERY helpful. Thank you very much!
[Epic 4G Android Development] syntax_erorr:
Gallery is hands down much smoother & faster when zoomed in on a picture compared to quick pic. Quick pic is only faster at loading / creating thumbnails the *first* time you add that directory to it.
[Epic 4G Android Development] SenseiSimple:
I've been running the test version of ShadowKernel 1.0.4, it's good of course. Since SleeperROM comes with preset for voodoo color, you should be ok either way. 1.0.4 has a fix to the yellowish default appearance of Voodoo Color kernels.

I'd recommend installing it!

Merry Christmas Everyone!​

12 hours after install, Swype notified me of an upgrade. Swype then became unusable with FCs. I like Swype, any suggestions?

Also, after getting home and plugging in to charge, noticed that the phone had shut down. Strange.
[Epic 4G Android Development] TexasAggie97:
What installation method did you use (full wipe pre-rom install, etc...) and do you have Shadow Kernel 1.03 installed?
[Epic 4G Android Development] Trident:
How do I turn off the pop-up sms notifications? Really annoying.

Also, I am having MUCH BETTER results with the default 1.0.2 Shadow kernel than any of the later ones. When 1.0.3 or later is used, wifi & 4G are both very unreliable.
[Epic 4G Android Development] Trident:
I did a full wipe x3 and it happened withe the default kernel. See above post for comments about later kernels. ^^^

I'm back on Shadow 1.0.2 now.
[Epic 4G Android Development] bbelos:
I believe there is an included SMS Popup app, you can disable the popups in there.

Your kernel issue is strange, because nothing i changed in versions 1.0.3 & 1.0.4 should have affected wifi or 4G.
[Epic 4G Android Development] ghostlegion7:
anyone having problems with usb still showing connected when after you have charged it?
[Epic 4G Android Development] Trident:
I agree that it's odd. I can only think that it has something to do with the switching back and forth- that's usually where the issue is. WiFi will work fine until I go out of range and 4G kicks in. Sometimes, I can toggle 4G off/on and will work for a little while, but once it idles, I have to reboot. And WiFi will reconnect, but not actually work. Meaning, the WiFi icon will be lit up, the settings will show connected, but whenever I try to open a browser, FB or the market, it says there is no connection.

I also think that it has something to do with the kernel in conjunction with specific ROMs. When I tried 1.0.3 with the beta Thunderhawk 3.3, it worked beautifully. When I used it with the released 3.3, I had the repeatable issues (same with 3.3 + 1.0.4). Sleeper seemed to be fine (but I didn't use it for more than16hrs with the default 1.0.2) until I tried flashing 1.0.3/.4, again, same repeatable issues.

I've been using it with 1.0.2 for the better part of today and aside from not very good battery life, it's worked well under heavy usage [Browsing, sms, calls, WiFi & 4G].

I now need to try Thunderhawk 3.3 with 1.0.2 to see if that works better.
[Epic 4G Android Development] Devtodi:
Just tried to attach a file to email and it fc'd the email app. Anyone else?
[Epic 4G Android Development] webslasher:
yes i have this issues even in stock rom, usually after charging via PC. And somtimes it just show usb connected, then disappear then appear again, then disappear.

Look like bad grounding
[Epic 4G Android Development] s1148625:
I had the same problem. Changed keyboard to Samsung default, removed Swype, downloaded the latest Swype beta and installed it. Has been working without any issues for 36 hours.
[Epic 4G Android Development] Adam_v1:
I wonder if this might be somewhat related to the problems I have been having using the Samsung dock. Most of the time after unplugging it the notification LED will stay lit red as long as the screen is on until you plug it into a power source other than the dock or reboot the phone. This happens on all GB kernels and ROMs I have tried so far.

From what I can tell what sets it off is something trying to use the notification LED while its charging, if I get a email or twitter notification overnight it will bug out but if I wake up in the morning to no notifications then it will normally be fine once I unplug it.

Even the initial behavior of putting it in the dock is odd on GB, it will turn on the screen right away and make the plugged in sound but the notification LED will not turn on to indicate its charging until 6-7 seconds later. If you turn the screen off right after plugging the phone in it will turn itself back on again when the notification LED finally lights up.

There must be something screwy with the base ROM/kernel that's causing this.
[Epic 4G Android Development] webslasher:
hmmm, getting notification while charging will screw up the USB notification right ? now thats interesting, seems like we're on the same case. Now can we really be sure this is not hardware related ? cause im not covered in warranty anymore..

EDIT: just tried reboot, then charging via usb cable connected to laptop, went fine, unplug and no twitchy USB connected notification.

Plug my cable again, try to make my notification light blink via sms popup, then unplug, the USB connected notification is screwed up, it says connected then disappear, reappear few seconds later and keep looping :eek:

reboot, the screwy usb notification is still happening :eek::eek:, turn my epic off, battery pull, then all booted up normal, no twitchy USB notification.

EDIT 2 : It look like it has to do with microSD too, but not really sure, can you try removing the sdcard, then plug your epic, and get notification, and unplug. Will the USB notification screwed ? mine got no preoblem if i remove my sdcard. Not really sure tho

EDIT 3 : Formatting my microsd and trying a clean install now, will report back later

EDIT 4 : nope, still getting them, although unmounting then remove the sdcard seems to be the workaround for me now
[Epic 4G Android Development] Devtodi:
Samurai legend

I am going to flash the new Samurai kernel (TW/BML Legend) and will report back. Yes, I just backed up and nandroided. Anyone with me?

UPDATE: phone is fast enough, haven't tried OC/UV yet, scrolling is a little glitchy but connectivity to 4G is strong. Benchmarked at 1750.
[Epic 4G Android Development] ghostlegion7:
i have tried numerous things to fix this issue as well... tried fixing permissions, formatting, clean install again and nothing... its very annoying and believe its something in the phone port itself....
[Epic 4G Android Development] SenseiSimple:
To everyone reporting a USB issue, presumably it's related to USB issues such as inability to remain off when charging, and possibly even unable to Odin while in download mode. Other symptoms might include LED notification stuck on or lighting erratically, usb debugging mode showing randomly while phone is not plugged in, phone showing as USB Device Malfunctioned when connected to a computer.

the Instructions were

So download that EC05 ROM from the link above, it will restore ALL of your partitions to stock froyo (something that doesn't happen with the GB stock package), then you can flash whatever ROM you want. (haven't tried MTD after this).

This was a complete solution to that issue, and was also syntax_error's result, see this post: http://xdaforums.com/showthread.php?p=20524690#post20524690
[Epic 4G Android Development] Adam_v1:
Sadly I don't think that's the issue for me, this ROM was installed as cleanly as I possibly could. I Odined back to stock EC05 with repartition checked, used Odin to flash CWM 5.0.2.7, upgraded the modem to EI22, used your clean slate tool to wipe and then installed the ROM and then upgraded to ShadowKernel 1.0.3+. The SD card I used for this install was a freshly formatted right before all this as well.

I know all this was overkill but I wanted to be sure I was starting as fresh as possible. I wanted to make sure I was not a victim of SD card or any sort of corruption after coming from MarcusantROM v1 and running a few different Samurai Kernel versions with known SD corruption issues.

Overall this is quite possibly the best ROM I have ever used and am VERY happy with it but this looks to be an issue with something from Samsung that everyone is building off of. Judging by http://community.sprint.com/baw/thread/82418 it would seem it is happening to a few other people as well (first hit on google for "epic gingerbread notification light"). It has also happened to me when running ACS ICS 4.0, 5.1, and MarcusantROM v1. I have not tested bare stock because I could not stand to use it for long enough to test it properly on the stuck light bug but it does have the odd dock behavior I noted earlier.

For me the fix for the stuck notification light is easy, just unplug power from my dock and plug it right into the phone and as soon as I unplug it from the phone everything is fine again. I have never had this issue pop up charging directly from the wall, only from a dock. I really never charge from USB so I can't speak for that. It's just a little quirk I have learned to live with but I thought I would mention it and see if it might be related to other peoples problems.

Edit: Forgot to mention that I got no messages or anything that would cause notification overnight and still ended up with a stuck charging LED this morning. So while notifications make it more reliably happen it will do it without any.
[Epic 4G Android Development] syntax_erorr:
Try following the directions in this post. I would also download the EC05 modem, and flash that frist. Then use clockwork to flash the mostly stock EC05 zip that is in that post.

Does your phone charge when it is powered off now? Or does the screen freeze on the big battery icon?
[Epic 4G Android Development] Adam_v1:
I'm really not sure how that is going to get things cleaner than Odin + repartitioning especially when it says right in the post it cant touch the modem. Odin + repartitioning should blitz everything on the internal storage, then lay down the partitions, then format them including the modem before writing all the data back on there. I did think to check when it rebooted after Odin and it did correctly show it had the EC05 modem and of course the EC05 to EI22 modem update flashed perfectly.
[Epic 4G Android Development] rsage:
Cool, was just about to flash, I will await the new version then :)
[Epic 4G Android Development] ansong:
I had this issue earlier. I'm not sure what the problem was but it went away on its own.
[Epic 4G Android Development] ansong:
Thanks for the great customer service! I flashed this last night when I saw your reply. Then I flashed 1.0.02 at noon today. Everything is working great. Any progress on the proxy issue?

I'll probably stick with your ROM for as long as you keep up with it as I don't really care for the ones that are themed to the gills.

Are you working on any particular improvements now?
[Epic 4G Android Development] rsage:
Hey there Sensei, sorry to bother you, just want to make sure since the OP seems unchanged but the hash is still the same - did you just re-upload a new 1.0.02 at the same link or is the upload still pending? Thanks again.
[Epic 4G Android Development] bit1:
This ROM is sweet OP.anyone not having haptic feedback working? Can't seem to get it to work no matter what I do.
[Epic 4G Android Development] chkchkboom:
Im gonna wait for the update version with no user apps...i spent to much time squaring stuff away to have to do it again....thats not to say im not perfectly happy waiting till it gets here.

Then maybe a review will be in order. :)
[Epic 4G Android Development] jasonrr987:
Is anyone else having problems with haptic feedback on this? Everything else is working great this is my favorite rom so far, keep up the good work!
[Epic 4G Android Development] SenseiSimple:
you're very welcome! I feel the same way, i like for it to look clean and simple, but have all the underlying power and features available.. i've spent a lot of time balancing out setting values and tweaks and making sure things don't interfere with each other

this release is mostly efficiency and fixes to 10.0.02, removed some apps, added a few back. a lot of the user apps had a tendency to be broken because lately, they are designed to only work straight from the market (like QuickPic). Proxy is next, will try to make it flashable if it's a simple thing (if anyone has any info on it, i'd appreciate it - hard to find those settings now i had info on it a while back but can't find it).

upload was pending... made some space and file system improvements but borked some things up so took a bit to clean it up they should match now for 1.0.03.

I haven't had problems with haptic, on first boot (clean install) it starts up turned on, but i always turn it off. I have noticed some random issues with certain apps when they've been restored but it's very random, something having to do with the app's user data.

GOOD NEWS, EVERYONE!

uploaded the Slim version, details of what apps are gone are in the OP under apps (hopefully it's easy to understand).

See the changelog for more info. Thanks for all the good feedback! Next on the agenda is proxy fix (i'm gonna experiment with it and if no difference i'll leave it alone) and the 1x/3g icon that's being eagerly awaited

Thanks to everyone who's tried it out - glad you like it

EDIT: COULDN'T wait any more so i re-upped with the 1x/3g fix!! fresh out the box.
[Epic 4G Android Development] SenseiSimple:
DONE and DONE! :D

check the latest version

Once you flash, to check the action,

1 - Get your MSL - can be found by typing getprop ril.MSL from Terminal Emulator

2 - Dial ##DEBUG# (##33284#) on your phone, Enter your MSL

3 - Scroll to "Others" at the bottom of the list.

4 - Choose HDR/1X Selection

5 - Change from Hybrid Mode to CDMA Only Mode. This puts your phone in 1X only mode.

6 - Press OK, wait 30 seconds, you should see joy - see the 1x icon switch.

7 - Repeat steps 4-6, and set Hybrid Mode to switch back - VERY IMPORTANT.
[Epic 4G Android Development] digiblur:
Awesome work... I know what I am flashing tonight.

The 1x fix is a must have. Like just now I noticed my speeds in the toilet. Checked the debug screen and sure enough 1x connection only. Not sure why 3g is down but it would be nice to know it.
[Epic 4G Android Development] SenseiSimple:
Thanks! i live in a dead-zone so mine keeps switching back and forth, i just like to know when i can expect slowness to say the least

Took the downloads down for the moment, i've noticed that certain things aren't being preserved across backups/restores when flashing - like SMS/MMS and logs, and other app data

from what i can tell this is happening in few roms, hopefully it can be sorted out
[Epic 4G Android Development] BeerChameleon:
Can't wait for the new version to be uploaded!!!'

Awesome now i can finally switch from froyo rom :D:D

[Epic 4G Android Development] bit1:
I've tried flashing clean. converting to ext 4 and rfs but still no haptic feedback. not sure why. I restored the original stock and haptic feedback is back. I didn't install anything after a clean install. I'm using ACS Recovery. could that be affecting some file?
[Epic 4G Android Development] BeerChameleon:
Sucks u had to take it down :(:(

I always wipe clean and just restore using titatanium, any chance u could post it up for people that use clean slate anyway? :confused:

And just put a note saying that.

You don't have too LOL

I'm just freaking excited to flash this baby!!! :D:D

---------- Post added at 11:07 AM ---------- Previous post was at 10:19 AM ----------

did u happen to get the new version before it was taken down? :confused:

If so mind uploading it for me and pm me it?

Thanks :D:D
[Epic 4G Android Development] HateMeILoveIt:
Darn. I was wanting to try this one. Guess I have to be patient... I HAVE NO PATIENCE! LOL :eek:
[Epic 4G Android Development] BeerChameleon:
Like wise :(:(

Hopefully he puts it up soon!!! :eek::eek:
[Epic 4G Android Development] digiblur:
I am the same way...nothing like having a clean os install. I install my apps from the android market from my pc. Pushes them all to my device. Then in use titanium to restore a handful of apps data and that's it. Keeps all the problems and FCs away.
[Epic 4G Android Development] HateMeILoveIt:
I've tried all the other roms and this one seems like one I'd actually stick with for more than 12hrs. Lol. Seriously, I need a daily driver and I think this could be it.
[Epic 4G Android Development] BeerChameleon:
ya its the only one with a plain theme, that i can work with, i really like his circle battery mod as its clean and green :D

I just first before installing go through the zip file and throw out apps and stuff i don't need and maybe add some theme mods to it ;)
[Epic 4G Android Development] webslasher:
Im not sure about bad partition, mine charged fine when off, but will try the post about flashing stock ec05 above when i got the time . Im on bandwidth cap now, i dont think i can download the rom with my 64 kbps connection

Edit : got another sympton, now everytime i turn on my Epic, it always detecting a usb connection, just when the media scanner is running. and just disappear.
[Epic 4G Android Development] dps33:
Screwed upmy install, update to 1.0.4 and got stucj at S (smasung ) screen ans tayed that. Tried to go back to 1.0.3 and same thing. SoIhad tore-install ROM and it worked. Now back to titanium to find al the things I had.:mad:

---------- Post added at 04:37 PM ---------- Previous post was at 03:54 PM ----------

Well

No phone, No Dialer. Getting Framework error. gAPPS. something liek that.

Going to try re-install after complete re-set. Wow, what the hack happened?
[Epic 4G Android Development] SenseiSimple:
When you restore from backup, sometimes (actually, more often than not) system settings don't work well and cause FC's. follow the restore instructions in the OP, and see if you fare better... don't restore "Accounts" or Settings (bluetooth/system).. as for the no phone, i'm not sure... sounds like a bad flash
[Epic 4G Android Development] dps33:
Thanks, I was able to do the same. Is it possible that Kernel came with ROM is 1.0.2+OC and I updated to 1.0.3+OC. When I show 1.0.4 out I flashed regular and not +OC. Would that mess up thing? :confused:
[Epic 4G Android Development] ColinPM:
Hi Guys

Thanks for your replies last week - it took me a few days to get past this problem. First and foremost, THIS WAS NOT A ROM PROBLEM.

After flashing back to EC05, redoing my ACS recovery and everything I could think of to get my phone back, I went back to my router (Apple Airport Extreme) and edited its configuration: no matter what I did, my phone would not work. The clincher was when my son's stock Epic 4G also stopped getting an IP address from the router.

I did a hard reset on the router and reloaded the configuration bit by bit. I use a list of reserved IP addresses on the router, reserved by MAC address. The router utility limits the number of reserved IP addresses to 25 and I had used them all. I also use a list of MAC addresses and a password to limit access to the router. One of those lists just did not work correctly, either because of a software problem, or because I had made a mistake.

The problem eventually spread to an iPod Touch as well so I put it down to a problem at the router, and not an Epic 4G issue. Right now it is working with 25 reserved IPs, and 22 MAC addresses, so I suspect that the problem was me: perhaps I fat-fingered the 3 MAC addresses.

As you can imagine, I am now significantly older and wiser!

Something else I learned this week is that the internal RAM size on the Epic 4G is very, very limiting. I moved all the apps I could to the SD, and then started to use Titanium Backup to force move some remaining apps to the SD (the ones that wouldn't let me do it 'correctly', and avoiding the widgets etc.).

It makes me wonder: has anyone ever heard of a disk compression utility for the built in memory, like a Stacker for android?

I might have to uninstall ThinkFree office because I can't move it to SD and it uses a large chunk of memory. I'd love to move Adobe Flash too, but it also won't move with Titanium Backup.
[Epic 4G Android Development] digiblur:
I wouldn't even waste your time with mac address lists for blocking others from using the router. Takes 10 seconds to get around that. Just use WPA2 with a good pass phrase and turn off wps. Good to go.
[Epic 4G Android Development] ColinPM:
Yeah, I know, but the hassle value of typing in a complex passphrase on some of my devices is significant. I am OK with it, but other family members are not :-)

Also, I know the tech level of my neighbors, and keep an eye on the DHCP clients so I have traded the security for convenience.

Having said that, my router has become a pain anyway so I may well follow that good advice.
[Epic 4G Android Development] webslasher:
Just tried these procedures,

> Format SDcard

> Flash EC05 modem back

> Flash the ReRFS rom posted earlier

> boot up fine

> flash EI22 modem

> flash sleepercleanslatefix

> Flash sleeperrom ensure clean install

still getting those annoying erratic usb connection in notification

> flash shadowkernel 1.0.4

still getting them, any ideas ? havent tried samurai kernel, link seemed down
