Sandman512,

Not sure if this is the same thing but this helped me get a lot more battery life:

Run your phone till its about 5% or less.

Plug it into the phone charger and then pop out the battery while its still connected. The phone will attempt to charge but won't (due to lack of battery).

Wait a minute or more and then pop in the battery (you can turn on the phone if you wish.)

*here you should see an instant increase of battery. This is because when the phone reboots/panics/etc.... it leaves some juice as a cushion.

Make sure to let the phone charge to full

Use it till 5% or less and repeat a few more times.

This should give you some more battery life and allow you to get an accurate battery reading.

If you have a generic usb cigarette lighter charger that will put out some decent amperage or any other power / chargers with a usb port you can make up a "charging" cable by shorting (or using a small resistor) the two data pins on the phone side of a usb micro cable. It will force the phone into thinking it's an AC charger and cause it to try to pull a higher current when charging. I keep a couple of these cables around for plugging into computers, other usb chargers etc. It works great even when tethered wirelessly, and running gps, maps, and an app that turns the phone into a bluetooth gps for my laptop in the car. It'll stay charged up and ready for use.

You can get some really cheap but good quality usb cables here. The place is great for HDMI cables as well.

Yes my reboots were on the included kernel with RC 2.0. Not on wifi, though. I flashed the 1.8.6 kernel and haven't had any issues yet. One thing that immediately triggered a reboot was the Flick Golf game that is on sale today for 10 cents.
[Epic 4G Android Development] dawinkley1:
Thanks

My wife got an Iphone for birthday, so I took her Epic to work to give to one of my employees. (it was a refab in the box as her old one had died and she wanted the iphone, so I exchanged the old Epic and luckily the refab was a EC05) On a whim, I rooted it (thanks for the one-click root..flawless) and then loaded up some different ROMs just to see if I could "stand" the phone (been with HTC's my whole life, with a rooted EvoShift right now). Loaded up Legendary yesterday, got it all set up the way I like it, and I'm stunned today... it's gorgeous, quick and so useful! Testing to see what kind of battery life I get, but Im seriously thinking of handing the Shift off instead.

So now I'm trying to learn all this Epic talk of odins and modems and all that... whew...

Just wanted to thank this Dev for a wonderful ROM and all you guys for the work you do.
[Epic 4G Android Development] zanderman112:
Feel free to ask anything. We have very knowledgable people around these parts.
[Epic 4G Android Development] scottyd035ntknow:
Yeah the epic is 100 times nicer than the shift imho and has the best keyboard out along with the vzw stratosphere clone.

Sent from my boost Epic 4G. Legendary rom, 1.5ghz Samurai.

Bluetooth enable and notification text issue

Anyone else having trouble turning on bluetooth on 2.1? Also, I am noticing that certain notifications, like the browser download notification, appear to be white text on white background so you can't see what the notification text is.
[Epic 4G Android Development] hoffman1984:
Yeah... but it's only active downloads... when they're complete the text turns black. That will be fixed soon.
[Epic 4G Android Development] hayzooos:
I dunno, not for me. I was on RC2 (with the included kernel) until last night when I updated to the 2.0.8 Samurai kernel last night. I never had a reboot before (and I was running RC2 since it first came out) and haven't had one since last night when I flashed the new kernel.

Speaking of which, what was the 'stock' kernel in RC2? Did it change to something else with the 2.1 update?
[Epic 4G Android Development] hoffman1984:
But the points we're trying to make is that it's NOT active with this ROM (if all was done right), unless you've flashed something over it that replaced one of the following:

DialerTabActivity.apk

ext.jar

framework.jar

services.jar

Or, as was said earlier, you came from the OTA GB, where the kernel replaces some system files as well.

Back to Froyo (EC05), and try again... I bet if it's done right this time, you don't get these results again.

CIQ is removed in this ROM and from what i can tell, all others... END OF STORY.

Not trying to be a jerk here... But you were fighting facts.
[Epic 4G Android Development] dead78:
ok, but in point of fact, all of those things were said to me after I pointed out what happened with my install. the tutorial video I watched made no mention of having to come from stock Froyo to completely eliminate CIQ, so you can understand why this information would have been entirely new to me. if it's been stated earlier than when I appeared in this thread that stock Froyo is necessary, please accept my apologies because I didn't see it.
[Epic 4G Android Development] hoffman1984:
All is good... But just know that we're here to help. So when someone who's posted multiple times throughout a thread with advice and guidance kicks a little knowledge your way. Just take it in stride... Try to find the problem based on information given, and if it's still an issue, please just contact one of the devs directly. We're happy to help all, but we don't need users mucking up the thread with misleading posts about what you think something is, and what it really is. Makes potential Legendary downloaders look the other way. And we're trying our best to make this the best possible experience for all.

Keep the suggestions and problems coming... we're trying to work through them as best we can.
[Epic 4G Android Development] KennyG123:
I have not gotten a single reboot on EI22. I have flashed every Samurai kernel as well. Am now on 2.08 and no problems. I feel the only ones on that kernel getting reboots have already damaged their processor by pushing it to 1500 Mhz. I have never OC'd higher than 1100 Mhz ever. My phone is rock solid.
[Epic 4G Android Development] JettMartinez:
Just for the sake of more data points, I've never overclocked at all and got the reboots on 2.08. It happened with low signal like was happening with the early GB leaks. I've been fine all day today on Samurai 2.01 (same place with the same low signal)
[Epic 4G Android Development] KennyG123:
Thank you JM. Are you also on the EI22 modem?
[Epic 4G Android Development] doggiedog:
I asked this same question a few days ago in page 183 that Kenny and Hoffman answered. Basically you have to go to:

Settings=>Applications=>All=>Launcher=>Clear data

That's what fixed it for me.
[Epic 4G Android Development] DeeODoubleD:
Thanks Kenny. I tried all this and still no go. It forced me to do a factory wipe to remove the main account which sucked but oh well. What is odd is that he added a few contacts today and it still syncs nothing. This leads me to believe there is a problem with his gmail account. It should have at least sync'ed what he added today.
[Epic 4G Android Development] colo-natas:
Ok, cool. There was another app notification that was doing the same thing but I can't remember it atm.

Is not being able to enable bluetooth a known issue? I use it daily so if it's just me I want to get to the bottom of it.
[Epic 4G Android Development] hayzooos:
First time I opened up bluetooth took a while for it to kick in. Reboot your phone, wait for everything to scan (SD card), and then flip bluetooth on. Wait up to a full minute if you have to. If it doesn't show up by then, I think it's time for a reflash because something didn't go right.

I use bluetooth all the time and don't have a problem with it on this phone. Every now and again it won't kick in (it'll like half start, kind of like wifi sometimes) in which case I can reboot the phone and it's working well again.
[Epic 4G Android Development] antmon:
well, ADW that is in v2.1 and Zeam that in installed afterwards doesnt auto rotate to landscape on the home screens or the app drawer, unless i open the keyboard....

anyone else notice this?

will try Launcher Pro next with this rom since that does auto rotate with my current ACS ICS v4
[Epic 4G Android Development] zetterwing:
I didn't see any issues until updating to 2.08. Then it was lag and freezing after a few hours of uptime. I tried tweaking through voltage control and nothing good came of it. This wasn't a clean install but after switching kernels all os well at the moment. I loves the initial speed but it didn't last.
[Epic 4G Android Development] KennyG123:
Are the syncs turned on in Accounts? I manually sync mine.

---------- Post added at 07:07 PM ---------- Previous post was at 07:04 PM ----------

It is something in your phone then. Zeam rotates in the app drawer just fine for me. There is a setting in preferences>general in zeam for sensor rotation. Make sure that is checked.

---------- Post added at 07:10 PM ---------- Previous post was at 07:07 PM ----------

For some reason my GPS fix got killed either after updating to 2.1 (not likely) or updating to Samurai 2.08. Reflashed the fix and all good, but something to watch out for.
[Epic 4G Android Development] antmon:
i will try zeam again and check the settings... don't think is a phone issue since ACS ICS v4 that came with Launcher Pro did rotate.
[Epic 4G Android Development] DeeODoubleD:
Thanks for your help Kenny. I didn't keep it simple and finally showed him adding a contact and asked if he chose phone or his google account. Ugh, you can guess the answer. Sorry to waste your time.
[Epic 4G Android Development] mbartels:
Is this a different way to calibrate the battery or something mutually exclusive? Are you saying to do this a few more times in a row and be done with it for good or is it something that should be done once a week or so to keep getting maximum battery life? After doing this should I calibrate the battery or does that ruin what I've done?
[Epic 4G Android Development] stilesja:
adw ex is rotating fine for me. Have tried horizontal calibration under display settings?
[Epic 4G Android Development] Ragnar:
I have used the launcher with the rom, adw and adw ex and they all rotate with no problem. You either have a hardware issue or a settings issue. I would check your launcher settings maybe vlear them all restart the launcher and delete any data for the launcher and test it out
[Epic 4G Android Development] KennyG123:
Not to raise a dead horse BUT if you run the Voodoo CIQ detection app and get a 370 and says that CIQ is active reflash K0nane's zip. I just did and now it says elements are there but appears inactive. His thread with the file is here:

just to weigh in on performance...

been running this since Monday, haven't experienced any reboots or any weird performance issues apart from the inability to change volume in calls that everyone's experiencing. only thing I've noticed is that battery life has been so-so. today, for example, I've been unplugged for about 6.5 hours and battery has dropped 17%. in that time, for about 6 of the hours my Epic has been near an Airave. I've made no calls, received one call that lasted under 5 minutes, and done nothing but run a few market updates and check email a handful of times. all in all extremely minimal use, and I have notifications on just about everything but email turned off.

so yeah, other than that, everything has been really smooth. nice rom.
[Epic 4G Android Development] KennyG123:
Thanks for that...it made me laugh. :)
[Epic 4G Android Development] LGK1:
I've got some weird behavior going on after Installing this this ROM I flashed my Epic from Hurricane 1.6 with EI22 Modem to this after doing Cache, Data and Dalvik Wipes but when I'm trying to navigate around it freezes and stutters I tried flashing the ROM several Times but the only thing that's not stuttering and freezing is my NAND Backup of Hurricane 1.6 every time I've update to this ROM I experience the same Freezing and stuttering is there anything else I can do I even tried the Format Options in CWM and then doing all the Wipes and loading the ROM and it once again was doing the stuttering and freezing :confused:
[Epic 4G Android Development] KennyG123:
Does it stutter and freeze before restoring anything? I mean did you try it right after flashing from full data wipe? If it works fine there then it is something you are restoring. Restore apps only with no data and see if that works still.
[Epic 4G Android Development] JettMartinez:
Yep, EI22.
[Epic 4G Android Development] LGK1:
Yes it immediately stutters after installing the ROM only no Data restore no logging into the Market or anything I even tried a different new MicroSD Card just in case and it still does it the only time it works fine is with the NAND Hurricane 1.6 it's very odd since I've tried several ROM's before 2.3.5 and everything has been working fine other then the random Reboots etc. that 2.3.4 likes to do which is why I would like to upgrade...
[Epic 4G Android Development] KennyG123:
Hmmm...interesting problem. You are flashing from Hurricane 1.6 each time? Have you tried Odining to EC05 stock, rooting and then flashing immediately?
[Epic 4G Android Development] LGK1:
I keep flashing back to the NAND Backup of Hurricane 1.6 since that's the last good and working backup I have of the Phone. I tried to flash this ROM got the stuttering and flashed back to Hurricane 1.6 and everything was back to normal I tried flashing it several times but not having any Luck and no I have not tried going back to EC05 Stock then Rooting and Flashing but will give that a try I just haven't had any weird problems like this after Flashing a new ROM it's only been the random reboots and Force Closes that were somewhat of a standard problem with the older ROMS but this stuttering and freezing is just very strange
[Epic 4G Android Development] KennyG123:
If that doesn't work, try a redownload as well.
[Epic 4G Android Development] mbartels:
I odined back to stock, didn't do the OTB GB update, cleared everything about 10 times, and installed 2.0 followed by 2.1. Downloaded Carrier IQ detector, ran it, and got a 270. That was a few hours ago, I just ran it again and scored a 470. Not doubting it's removed (frankly I'm not that worried even if it's not) but I wanted to let you know.

EDIT: One thing I did between getting the 270 and 470 was restoring my text messages using SMS Backup & Restore. Would that alter one of the four files mentioned above?
[Epic 4G Android Development] zanderman112:
I still don't know why people said upgrading to gb via ota then rooting messed stuff up. Tis what I did. All you had to do was use odin to flash a kernel, then cwm was able to stick.
[Epic 4G Android Development] jarcher12:
I would be quite happy with a 17% drop in 6.5 hours, i get more like 30% drop under the same conditions !
[Epic 4G Android Development] Ragnar:
OK so when are we taking this rom to MTD and Yaffs file system :-)
[Epic 4G Android Development] MeetFace:
+1 10charz
[Epic 4G Android Development] G.I.Geoff:
Sounds like an install gone bad. Like really bad. redownload, reinstall the ROM, and do a pre-theme wipe (davlic cache and cache). And then fix permissions and reboot. Usually the issues you described happen when the file system gets messed up or a download has error and messed up files in the .zip (this is from my experience. Anyone wants to correct me please do)

*and that is so the wrong thread. How did I even get here? Lol my bad
[Epic 4G Android Development] jarcher12:
here is my -18 % after 4 hours extremely light use.

and i am actually ok with that, much better than on froyo for instance.

;)
[Epic 4G Android Development] dead78:
one thing I'll share in case you missed it earlier...

I was getting a score of 370 and "active" every time I ran Voodoo CIQ detector...and I ran it about 10 times over a two day period. Earlier today I decided to reboot the phone, and ever since then all CIQ tests with Voodoo show CIQ is present but inactive. Most recent tests have yielded a score of 170. The whole thing is a bit odd.
[Epic 4G Android Development] flastnoles11:
Again... new app that still doesn't have. The quirks out... give them a few weeks and supercurio will have that app working perfectly. Right now it is not completely accurate and you should take anything it gives you with a grain of salt
[Epic 4G Android Development] tclarkey:
dumb question, but what do the colors under phone signal represent?
[Epic 4G Android Development] flastnoles11:
Yellow is "ok" signal. Green is "good" signal... I never have green! Lol

And where it's just plain ol' brown, like crap color, the phone signal is crap?
[Epic 4G Android Development] flastnoles11:
Youu got it!
[Epic 4G Android Development] esuuuu09:
From what i read, it resets the battery calibration. You only need to do it once. It basically releases the extra battery that your phone is conserving due to a history of kernal panics and whatnot (reboots).

How is that method different from using this app:

That was also already asked back in the thread. The app just guides you through the procedure and automates some of it. I never tried it though.

[Epic 4G Android Development] maltydog:
My phone is rebooting endlessly now. Not sure why, it was fine when I first installed the Rom. I tried changing back to the earlier kernel as suggested in this thread but it has not helped at all. I think I may have to rewipe and try something else.
[Epic 4G Android Development] hayzooos:
I'm still running RC2. I upgraded to the Samurai 2.0.8 kernel the other day, and things went fine for about 24-36 hours. Then it really started to slow and I got my first ever random reboot (at least I think) since being on EI22. I now changed it back to 2.0.1 as it's the newest older version I had on my SD card. So far, so good.
[Epic 4G Android Development] algorhythm:
Agreed. I've gotten like 10+ reboots the past 3 days. I tried Samurai kernel 1.8.2 and got a few random reboots, kept getting them suddenly on the included kernel, and I am now on 2.0.8 and got one or two already.

It is EXTREMELY strange.. this rom was absolutely rock solid the first few weeks, but suddenly I get reboots multiple times per day.
[Epic 4G Android Development] Joph:
thanks! seems to work now.
[Epic 4G Android Development] Ragnar:
I was just messing around, but this is incredible, because I hate Odin and I didn't want to start using it to go back and forth between my two roms. This is like an early Christmas gift.....
[Epic 4G Android Development] altimuh:
I've been seeing more and more posts on bad battery life and reboots.

My one phone is on RC1, and aside from some occasional reboots - battery life seems average (not sure it's as good as srf 1.2 yet).

My other phone is on RC2.1, and I'm having abysmal battery life. (I was getting some reboots, but I since have toned down my undervolting.)

I've run BetterBatteryStats: attached are some screenshots. Does anything here seem to be the culprit?
[Epic 4G Android Development] hayzooos:
Your phone has been awake for 5.5 hours while the screen has only been on for slightly over 30 minutes. I would check the wakelock part and see if something is sticking out there...

Unless you're constantly streaming audio or something, I don't know what else would be keeping your phone awake all that time while the screen is off.
[Epic 4G Android Development] flastnoles11:
Check your wakelocks. Anything abnormally high isn't letting your phone go to sleep...
[Epic 4G Android Development] h4kudoshi:
uhm, yea so wrong rom. sorry however i am now flashed to this rom so time to try it out! :D
[Epic 4G Android Development] altimuh:
That's what I thought too! But I said, "nah, what the heck would be keeping my phone awake! Maybe I'm reading this wrong!" Perhaps I should have trusted my instincts...

Here's a few screenshots of the different wakelocks.
[Epic 4G Android Development] algorhythm:
Is that... comic sans ms on your phone? bleh
[Epic 4G Android Development] altimuh:
lol yeah - it's sort of my signature font :D
[Epic 4G Android Development] hayzooos:
I think it's that 'mcc_delayed_work' or whatever it is. I know the vbs something or another is when your phone is charging, so you don't need to worry about that. Whatever the delayed_work one is, that's probably your problem. Hopefully someone with more knowledge than me can chime in and let us know what it is.
[Epic 4G Android Development] maltydog:
I decided to reflash the same older kernel (Samurai 1.2.6), this time doing a cache/dalvik cache wipe first, and the reboots have stopped for the moment. Keeping my fingers crossed.
[Epic 4G Android Development] altimuh:
I googled 'mmc_delayed_work' and some people were talking about it being related to wifi. I opened up my wi-fi settings and (while connected to my wifi) it kept on scanning for networks. Is that normal? If not, how the heck do I get it from repeatedly scanning for new networks?
[Epic 4G Android Development] hayzooos:
I don't believe so, no. I know there is a way to change the timing on how often the wifi scans for networks, but I cannot remember where that setting is now. You may want to snoop around in settings for something like that, or maybe it's within the ROM or kernel, but my guess would be ROM if one of those two.
[Epic 4G Android Development] rkcrawl:
When you have the network setting open, its scan every 5 seconds. When its closed, it will scan only once every X seconds which is set in a file I don't recall now.

I went to increase mine to 300 seconds (5 mins) and found that it was already set.

I'm on RC2.1, Samurai 2.0.8 kernel, and I'm getting pretty good battery life. I'll give it a good test this weekend. I'll be in the woods Sat/Sun probably better then 12hrs each day.
[Epic 4G Android Development] altimuh:
Ok thanks - so if that's not it - what's forcing 'mmc_delayed_work' to keep my phone awake?

I too am on RC2.1, Samurai 2.0.8. I've removed SNS, and I'm running Superfreeze. I've MetaMorphed (changed font), and my Voltage Control Settings are as follows:

i/o - noop

gov - conservative

min - 200

max - 1000

All voltages are undervolted 25mV.

Another odd thing I noticed is that only 600, 400, 200, 100 are now "supported" by VC. Prior to my Samurai 2.0.8, I had everything between my min/max.
[Epic 4G Android Development] KennyG123:
Mine keeps scanning every few seconds with the network closed. No interval I change makes a difference.

Hoffman, can you look into making the wifi scan manual only?
