[Samsung Epic 4G Touch] wase4711:
what kind of life are you getting, and how do you use your phone?

Since this is a powerhouse, super phone, that does tons of stuff, if you are a normal, "power" user, I would say getting 12 hours of heavy use is pretty darn good; if you only use it for calls, email, and texting, then you should get around 18 hours, and, if you rarely do anything but make calls, you should get around 24 hours

Think about it; of you use a laptop, you are lucky to get 3-4 hours of use on it; these phones are at least a "powerful" as a basic laptop, and, you get at least 12 hours or so out of the battery on it..

I think peoples expectations on battery life FAR exceed the reality of what a battery can actually deliver. and, as we get into the colder months, especially in chicagoland where I live, battery life will be even less..
[Samsung Epic 4G Touch] akarol:
Ok guys, I need your help in determining where this yellow glow overcroll effect came from in my phone. Not that I mind it at all, but I'd like to clean the culprit file from this tweak and re-upload it to Calk.

Anyone notice their phone has a yelllow glow overscroll effect (to check, go to Settings and scroll all the way up and down)? If you do, did you flash the Market Fix .zip or the Hotspot framework.jar that was posted here?

Thank you in advance for your help.
[Samsung Epic 4G Touch] bluefire808:
I had battery problems alot. For me rhere is one thing I can do to fix 100% of the time. Let it full charge with the phone on. Calibraye battery. Run the phone till it dies then with the phone off after it dies charge it ( phone off ). When you turn you phone back on you will have the best battery life you can get garrens
[Samsung Epic 4G Touch] HondaCop:
No overscroll effect here

[Samsung Epic 4G Touch] Duce HD2:
With this rom running it out of the box I get slightly better than what I used to get with pure stock. With moderate to heavy use (mainly web + text, calls not so much, maybe 30-40 minutes) after10 hours of use I'm at around 50% battery consistently. So, on a regular day I personally average 18-20 hours, on a day off work where i sit and play with it nonstop 10-14 hours. I'm not one that UCs, turns data off, lowers brightness all the way, and leaves it on standby for 95% of the time, I like my phone to do what it's supposed to do, be fast, responsive, impress me with its display (and others), and be stable. Battery..meh, as long as I can get to mid afternoon on one charge I'm good..
[Samsung Epic 4G Touch] playya:
I must admit I do get very good use out of my phone when I run it all the way down and recharge just like you have posted. I also run my phone at 800 mhz
[Samsung Epic 4G Touch] steelersmb:
Man, this is driving me crazy. Everything was working fine but then I got a LOS. I am using tasker and it rebooted my phone. Now my phone constantly reboots when it starts up. This is like the second or third time this has happened to me and only with this ROM. I am going to flash one more time but may have to go back to Starburst because it's driving me crazy.
[Samsung Epic 4G Touch] rickyq12:
SAME EXACT thing happens to me. Gets really frustrating cause I really like this ROM. I thought I was doing something wrong, but I see others are having the same issue.

It's like we can't reboot or go into recovery cause we will get into a bootloop after a simple reboot.

So, should we try to prevent from rebooting the phone when running the ROM?

And yes, I manually wiped the required wipes prior to flashing the ROM.
[Samsung Epic 4G Touch] playya:
did you see the responses above to possibly fix your issue
[Samsung Epic 4G Touch] greatlakesghost:
Have you tried a different kernel? I had the same issue but went back to 1.0.0.1exp kernel and have been fine ever since. I have flashed a couple of themes since having this setup so I have a few reboots and not one issue. The newer exp kernels just act wonky on my phone. Just a thought. Good luck :-)
[Samsung Epic 4G Touch] Lento10:
I am using ADW EX with no problems, I restore it from a back up, using TB.
[Samsung Epic 4G Touch] meatwadathf:
You Can't change voltages with setcpu on a stock kernel. Only on rogue modded kernels. If you need to do it on a stock kernel, use tegrak.
[Samsung Epic 4G Touch] scarmon25:
OK. That may be the confusion that I was having. I am on a rogue kernel but its the stock EL29 kernel with rogue recovery. Which I use tegrak just fine on. But with hit man of course I use Set CPU or voltage control. So when you say stock kernel that's the one I think of. The included standard kernel with rogue recovery. And modded I think if hitman.
[Samsung Epic 4G Touch] meatwadathf:
Yup, stock= stock with rogue cwm. Modded=gunslinger, hitman, desperado, etc..
[Samsung Epic 4G Touch] Indrid Cole:
More details plz. I've never heard of this. Whoa. Is the phone alred on when holding power. Or off?
[Samsung Epic 4G Touch] Ja5oN:
You know that is what I thought... I got in a argument with some dude in Q&A about the same thing the other day. He told me that he was totally stock except for root and he was able to overclock with setcpu. He even loaded a screen shot and it showed to be true. Is this possible because I always thought the same thing: Stock-Tegrak / Custom Kernel-SetCPU.
[Samsung Epic 4G Touch] agentfazexx:
As of lately whenever I update Market apps, my phone goes into Airplane Mode...
[Samsung Epic 4G Touch] meatwadathf:
Simple solution... Load a stock kernel and try to overclock w/ setcpu yourself. People lie for whatever reasons.
[Samsung Epic 4G Touch] scott500:
Just a couple quick questions of I could..

Is there a way to uninstall Go Launcher from the rom. For some strange reason there is no option to under manage applications to uninstall it.

Also, has anyone reverted the app draw back to its normal size. The 5x5 is a little crowded for me.

Anyway...thanks in advance for your thoughts and thank you for the great rom!
[Samsung Epic 4G Touch] agentfazexx:
Use Titanium Backup root to uninstall it.
[Samsung Epic 4G Touch] sdglenn:
Anyone have a link to v 2.7. I don't remember high aos on el26
[Samsung Epic 4G Touch] Moebius01:
Ok, since this thread is pretty darn long now, it's a bit much to go back through. So, I'm going to throw a couple total noob questions out there, put on the flame retardant suit, and hope for the best.

For background, just picked up an E4GT last month after nursing a Touch Pro (running one of Calkulin's roms actually) along for more years than I care to admit to. Back there, flashing was pretty straightforward. Unlock, flash rom, yank battery, reboot. Now, there are roms, kernels, recoveries, CWM, ODIN, CPU scripts, undervoltage... enough to make a head spin. But, I've had the phone for a bit and gotten used to the os, so it's time to learn this stuff and flash.

I've got it rooted, and ClockWorkMod installed. So for the noob stuff... When I get ready to flash the rom (waiting for 2.9 to give me some more time to do the learnins), I use CWM to run the formatall zip, then the rom zip - do I need to install a kernal, or is that part of the rom? Also, as far as modem/radios go, same question. Are they part of the rom, or separate entities? And finally, all the conversations I'm sifting through on SetCPU and voltage and cpu scripts, is there default stuff on the rom to begin with, or do I need to do something once I flash to get all of that working?
[Samsung Epic 4G Touch] beseenwithgreen:
I believe each ROM comes with some kind of a kernel in it already....modems i think are a separate thing on their own....but Im sure someone more knowledgable can prove me wrong and inform better you :)
[Samsung Epic 4G Touch] kgatlanta:
GPS won't lock in after upgrading to 2.8.1

I did an upgrade from 2.5 without doing a clean wipe first, could that be my problem? Anything I can do to reset the GPS without wiping and re-installing?

---------- Post added at 03:36 PM ---------- Previous post was at 03:34 PM ----------

Santi, is there a known GPS isue?
[Samsung Epic 4G Touch] Indrid Cole:
They aren't lying. It's a medical condition called verbal diarrhea.
[Samsung Epic 4G Touch] shakewell:
after you iosntall the rom check the verison numbers ,, you will have to do a el29 radio update

and should be good tto go
[Samsung Epic 4G Touch] Moebius01:
Which reminds me of one other question. Is there a site anywhere that breaks down all the version stuff? Looking at my phone, my build and baseband both show EK02, but most of the roms I see mention the EL numbers (29 in this case). What's the difference?
[Samsung Epic 4G Touch] JohnCorleone:
You will get it all except the modem. Actually if built off of the official release then it could have the modem too but basically you will flash the format all zip, flash the ROM (which will definitely come with a kernel) and you're good to go. The scripts will run automatically since it looks like he is going with Rogue kernel. Now the part that gets tricky (correct me if I am wrong) but if you run SetCPU to overclock then it overrides some of the scripts. Calkulin's default settings are best for most people. He seems like a dev who actually tests for more than 5 minutes before release. I am willing to bet he's putting Hitman through the paces to see if he should include that rather than Gunslinger. Which from what I have seen it is Gunslinger with the Touch Recovery instead of Rogue Recovery
[Samsung Epic 4G Touch] Bazirker:
No flame retardant suit required!

Each ROM comes with a kernel, so no need to flash one. Modems, on the other hand, are different; you need to update that separately. I've had the best signal and battery life with EL13 but have read that EK02 and EL29 are preferred by others. YMMV.

This ROM, by default, runs its own script to adjust voltage and CPU frequency. By default, it runs -50 mV and scales the CPU frequency as described in the OP. If you so desire, you can modify the script to suit your own needs, or you can use SetCPU or other similar programs. One nice thing about this ROM is that if you are using SetCPU, Tegrak, etc., this ROM detects that and lets that take charge rather than the default built-in script.

Did I get everything? :)
[Samsung Epic 4G Touch] Duce HD2:
Anybody using route hitman kernel see any battery improvement? Or stock still better? Thanks
[Samsung Epic 4G Touch] Isriam:
stock seems better
[Samsung Epic 4G Touch] darren.wlsn1:
i get better battery life but a lag when switching homescreens but its small lag and batter improvement is worth it.
[Samsung Epic 4G Touch] Dchibro:
The guy probably rooted quite while back via the Zedomax or LoStKernel, but is running the stock ROM so he thinks he's stock.
[Samsung Epic 4G Touch] JohnCorleone:
Tegrak and Mobile Odin have updates. The Tegrak update speaks of added custom kernel support but I haven't messed with it yet. Where are you guys seeing lag on Hitman and what governor?
[Samsung Epic 4G Touch] Quocstazz:
I see lag on the home screen when trying to go from page to page on the home screen. Not sure what my governor is but I just flashed it over calkulin 2.8.1.
[Samsung Epic 4G Touch] JohnCorleone:
Is this in Touchwiz launcher? I am on ADW EX and don't see any of that behavior but I still want to help troubleshoot. Maybe some voltages were scaled back in Hitman. Let me go check the changelog....
[Samsung Epic 4G Touch] KBizzle:
I am also one of the few with lag. I didn't change my on demand settings and conservative is what's turned on in calks roms. Also was running the -50 mv undervolt that comes stock on his rom. I tried oc settings at 1.2, 1.4, and 1.5 with no change in the lag. Yes, I was running TW, no launcher but in my recent experience, with stock Kernel TW was the only launcher that was consistent with no lag.
[Samsung Epic 4G Touch] JohnCorleone:
Hmmm...there must be some voltage or governor tweaking or something going on in the kernel. Changelog didn't help me and github is over my head
[Samsung Epic 4G Touch] KBizzle:
I could try running Hitman on a Stock Rom without the tweaks and see what happens. Could be clashing with the kernel some how.
[Samsung Epic 4G Touch] rokair:
3cpufreq_screenstate_scaling

Hmmm. I'm not an Android programmer but still I didn't expect this part to be hard.

I have modified the default 3cpufreq_screenstate_scaling script so that when the phone is plugged in (no matter the current % of battery charge) the MAX Freq will be set back to 1.2GHz. I generally have this working fine but I have noticed the following.

It seems that the trigger for this script to execute is when the phone is put to sleep or woke up (with the power button or a general timeout).

So, when the phone is unplugged, at say 80% charge so the MAX Freq is at 1Ghz, and the screen is on. I plug the phone in but it stays at 1GHz until I turn the screen off and back on.

Is there an easy way to make the script execute when the charger is plugged in / unplugged? Seems like that should have been an easy one to find but I am not having any luck.

Thanks,

Rokair
[Samsung Epic 4G Touch] JohnCorleone:
Good thinking. The baked in undervolt could slow things down if kernel is undervolted tooo
[Samsung Epic 4G Touch] Dchibro:
Well a simple test would to install SETCPU and reboot. This will disable the underclocking script. If no change in homescreen lag, then boost the voltage at the top end CPU steps by 25 increments and test each time. That should tell you if it's a voltage issue or not.
[Samsung Epic 4G Touch] KBizzle:
Good Idea.
[Samsung Epic 4G Touch] JohnCorleone:
Great idea actually
[Samsung Epic 4G Touch] nibrwr:
Stupid thanks button!

I'm pretty sure any changes included in that script are initiated by turning the screen off if the display is already on
[Samsung Epic 4G Touch] rokair:
Note that if you look at the scripts the undervolt script does not include the exceptions to other applications such as SetCPU. Also it sets the voltages to exact values and not by a subtraction.

Of course this might still be a good idea in general.

You could also remove the scripts (of course with a backup copy) from /etc/init.d and that would certainly remove their actions.

---------- Post added at 03:34 PM ---------- Previous post was at 03:32 PM ----------

Yes...they do seem to be initiated by turning the screen off (Timeout or Button) if it is on...and by turning the screen on.

I'm looking for a way to also initiate them by plugging in the charger or unplugging the charger. (Thanks though...;)
[Samsung Epic 4G Touch] scarmon25:
That's what I do. I use Tegrak and I remove he under volt, and CPU tuner scripts from system/etc/init.d. I leave the ones that don't mess with frequency and voltage. Works like a champ.
[Samsung Epic 4G Touch] coiledwire:
I don't know about an easy way. You have to find which flag is used to indicate if the battery is being charged. Then you need to make that the priority over screen state by adding to the logic such that your charging config is selected despite the screen state.

Not too difficult, but more than editing 1 or 2 lines.

[Samsung Epic 4G Touch] JohnCorleone:
I altered one of the scripts quite a bit with a little help from a friend...my phone didn't like 800 at all. Lots of random menu popups
[Samsung Epic 4G Touch] KBizzle:
So, initial use, I have no lag. I never thought of rebooting after installing SETCPU. Also didn't know the kernel was undervolted. I'll report back if I see anything.
[Samsung Epic 4G Touch] rokair:
I guess I am just confusing everyone (Sorry-thanks to JohnCorleone/nibrwr/coiledwire for you replies).

The script works as I have it. The problem is simply that it seems the script only executes when the screen is switching states.

JohnCorleone:: I actually have it right now so it runs at 500MHz anytime the screen is off (charging or not). It runs at 800 when the battery is below 35% and it is unplugged. It runs at 1GHz when the battery is above 35% and it is unplugged. And, it runs at 1.2GHz when it is plugged in regardless of the battery % and the screen is turned on.

My only issue is that the script only seems to run (so it can trigger a change in the MAX Freq based on the already valid conditions) when the screen is changing states. All of the above script works great. I just have to remember if the screen is already on when I plug it in I have to turn the screen off and then back on before I will get the performance boost.
[Samsung Epic 4G Touch] spongaweb:
Noticed my baseband was el13 and updated modem through Odin, seems to have fixed it

Edit: anybody get chrome beta working?
[Samsung Epic 4G Touch] agentfazexx:

[Samsung Epic 4G Touch] neverends:
I love Calkulin's ROM and it is my daily driver...

I fully understand that developing such a flawless rom takes time and that Calkulin does this because he likes it and this is not his 9-5

I also fully understand that out of respect we do not ask for ETAs

I only have one simple question...

Why post that an update is coming... a full week before it comes out...

I can understand if Calkulin was coming out with an ICS rom and wanted to build up the hype... But it seems as thought the jump from 2.9.1 to 2.9 is more of a maintenance updated and nothing ground breaking...

I guess to me coming soon means 24 - 48 - or even 72 hours Not hey the rom is just around the corner and will be released in only 192 hours...

With that being said I love this rom and am still looking forward to (as I have been for the last 7 days) its release!
[Samsung Epic 4G Touch] Dchibro:
To let people know that an update will be coming (at some point) and what he has in mind for it? A full week? Really? You say that like it's an eternity. I know you're trying to be as polite and appreciative as you can, but I think your expectations are a bit off, otherwise you wouldn't even ask.
[Samsung Epic 4G Touch] neverends:
Like I said in my post... updating the post to show coming to me implies coming soon... the list of changes implies update is completed and being tested for final release...

I would not expect someone to post coming if they had just decided what changes they would make to a future version...

I know there are other people on the forum like me who may have wanted to try blazers new version or the cm9 build and saw the post on 2.9 and decided to wait it out for the new calkulin rom which they are already used too and comfortable with.
[Samsung Epic 4G Touch] neverends:
You are correct... my expectations must be off if no one else feels the same!
[Samsung Epic 4G Touch] rokair:
Unless you have donated a large sum to Calkulin you must remember that he is maintaining this ROM on his own time with no obligation to do anything. Please be respectful of the efforts he is putting into this ROM and simply wait. If you feel you cannot wait then I'm sure the other options you have listed are also fine ROMs.
[Samsung Epic 4G Touch] dvtmg704:
Does 4g work with the hotspot app on this rom
[Samsung Epic 4G Touch] meatwadathf:
Flash it and test for yourself ;).

J/k. Yea. It works.
[Samsung Epic 4G Touch] KBizzle:
Well i seem to have fixed my lag issues. Pretty damn happy. Just to see how the battery does tomorrow.
[Samsung Epic 4G Touch] Dchibro:
So what did you do? Did it have anything to do with my SetCPU suggestion, or something similar?
[Samsung Epic 4G Touch] Mr Global:
There is going to be a 2.9 release? Does anyone know when that is coming out? :D
[Samsung Epic 4G Touch] meatwadathf:
I heard soon.
[Samsung Epic 4G Touch] agentfazexx:
Stop asking!!! We had two pages of flaming for this same question! Don't ask for ETA's!
[Samsung Epic 4G Touch] KBizzle:
Yes. Installed SETCPU and then rebooted. Ran well then. Went ahead and ran the odex script and now everything is smooth as butter. I had just not ever rebooted. Got mad and immediately flashed back to stock Kernel. Lol.
[Samsung Epic 4G Touch] KBizzle:
Whoa! He put a smiley, indicating sarcasm.
[Samsung Epic 4G Touch] JohnCorleone:
Maybe he is considering baking in Hitman kernel but wants to test it thoroughly or see if any changes need to be made to make the two run even better together....
[Samsung Epic 4G Touch] tdunham:
I can see how you got your tag name cause it JUST NEVERENDS (rofl).

Seriously though, I haven't had any problems with lag and I use Go Launcher so that is probably why. I'm actually glad you observed that because I've been roughly following Rogue's thread and I don't think anyone has pointed that one out, or I may have missed it. Plenty of suggestions to overclock, undervolt (no undervolt) and it goes on forever people trying to get the bugs out.
[Samsung Epic 4G Touch] asteetva:
Question Regarding Default Profiles and -voltage zips

In the OP it says

Preset profiles are:

1.2GHz - 100-85%

1.0GHz - 84-36%

800MHz - 35-0%

And just an FYI, even at 800MHz, the phone still operates very well & smooth but the battery saving are the real benefit

Now I am not a tech savvy person so my question is do I need to edit the init.d to have "800MHz - 35-0%" or it is used by default.

Also this does not have any connection with the -5v,-75v,-100v zips that are available for download right?

Once again all I know is how to flash not really tech savvy like lot of users here.
[Samsung Epic 4G Touch] adima:
Anybody having problems with the screen going black after boot animation? It's happened 3 times in the past 4 days and the only fix i've found is to reinstall the rom. Wiping the cache and dalvik doesn't work.
[Samsung Epic 4G Touch] EeZeEpEe:
The preset profiles work by default. You can check for yourself with SetCPU or ROM Toolbox when you go below 85% and 35%. Also the zips are for undervolting. -50v is already built-in. You can try -75v or -100v but if you end up getting restarts go back to -50v.
[Samsung Epic 4G Touch] tdunham:
Is there a way to check under volting without using an app like Setcpu that will disable the unit.d scripts?
[Samsung Epic 4G Touch] asteetva:
Thank you for explaining very precisely.
[Samsung Epic 4G Touch] darren.wlsn1:
what kernel are you using?
[Samsung Epic 4G Touch] adima:
I believe it is stock?..since I flashed this rom a couple wks ago after using blazer w/ rogue 1.4 and have not flashed rogue yet.
[Samsung Epic 4G Touch] darren.wlsn1:
not sure then... are you wiping properly? (lol) sounds like part of a theme or something is left over causing issue.
[Samsung Epic 4G Touch] adima:
I'm using caulkins format all to wipe before I install a rom
[Samsung Epic 4G Touch] meatwadathf:
How long are you waiting exactly? Let the black screen go for atleast 10 minutes. Could be it is booting but the boot animation is somehow messed up and it is really just booting. The first one is always very long. 10 minutes is probably exageration but let it go just to be safe.
[Samsung Epic 4G Touch] carhauler1969:
Trying to download from the phone on wifi, says starting download, then instantly fails every time, weird. Actually anything I try to download fails immediately.
[Samsung Epic 4G Touch] meatwadathf:
Its a torrent file. You have to use a torrent client. Not sure if they have torrent clients on android. If you are not familiar with torrents, look here: http://www.utorrent.com/help/guides/beginners-guide

Essentially download utorrent, install it, and open the .torrent file I posted with the utorrent program. It will then download calk's rom directly from me and anyone else who is sharing the file.

EDIT: There ARE torrent clients for android but I am not familiar with then so cannot recommend one.

EDIT 2: did some research and ttorrent pro seems like an awesome android torrent client.
