Entropy, got a new uckk6, but from all I've read it seems I should flash uckh7, that's your opinion currently am I correct? It seems I can get a hold of the correct clockworkmod recovery for that too because the download links for cwm for uckk6 don't seem to be working anyway. I guess I'm just wondering what's best to do with this new phone...coming from an infuse that took a crap on me.

Anybody have any ideas of what would be ideal to be running on this thing? Stock rooted uckh7 with your 2/7 kernel?
[AT&T Samsung Galaxy S II SGH-I777] :
I'm on UnNamed 1.3.2 which is the final from built off of KH7 and it has been fantastic for me.

A lot of other people are hellraising i9100 roms and are liking them. Just about anything is better than KK6 at the moment... just depends on if you want an AT&T build or a European Samsung build.

Is the OC a secret or something?
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Max is 1.6! oc/uv settings are accessed with setcpu or voltage control all from market
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
If OC is the only reason for installing this kernel, then I would not advise it. I've put in a lot of basic fixes for power management and stability, OC is just a lucky additional feature that I put in because it was highly requested and it was low-hanging fruit thanks to codeworkx having an easily cherrypickable commit.

However if people are consistently irresponsible in use of the feature, such as not realizing that every device is different and that one person's OC or UV success means NOTHING on another device, I might have to pull the feature.

I ask that no one discusses undervolt settings in this thread - as every phone is different, giving someone undervolt settings has no guarantee of working. People need to learn how to zero in on voltage/clock settings themselves - "Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime."

Entropy, its seems the 10/9 "experimental" kernel has been successful experiment. :) I've had no issues, whatsoever. Great battery life, stable as a rock.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
It's been good for me so far.

I think I'm going to take a break for a few days (the past week was a MAJOR development sprint due to being sick) and let people beat on 10/9 Experimental. 10/9 Experimental seems to remove high Android OS reporting from the battery stats, however sleep statistics and actual drain don't seem to be any better on my device. However, having sane reporting in battery usage stats IS a good thing when people DO have drain problems.

If 10/9 experimental is consistently good for people I'm going to make it my baseline.

At this point I'd ask that people try 10/9 experimental first, then IF you have problems, run 10/9 non-experimental to see if the bug is specific to the experimental branch.
[AT&T Samsung Galaxy S II SGH-I777] mjgspr95:
Experimental didn't do well with OC for me. Just letting you know, I know thats not your prority. The stable 10/9 is doing well a day in with OC.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Hmm, that's odd. I'll look through the patches to see if there's anything that could've affected OC, but I'm fairly certain none of the cpufreq code was touched... most of that is in arch/arm/mach-s5pv310 anyway...

Edit: Can't find anything yet. I'm really inclined to move towards Experimental unless I get any more negative reports. It contains a bunch of general fixes, including, it seems, that patching up to .14 is the key to getting sane stats in Settings->About Phone->Battery Usage. Android OS is no longer an insanely high percentage - although it has also proven that the "bug" was display-only - battery life is approximately the same. AOS was, in my case, not draining the battery.
[AT&T Samsung Galaxy S II SGH-I777] nyydynasty:
i find that UV'ing doesnt save on battery life anyway.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Voltage control (either over or under) is sometimes needed for stability when OCing. As clock gets higher, the safe voltage range narrows - high voltage causes overheating which causes crashes, low voltage causes crashes directly.

UVing the core on most devices saves at most 5-10% CPU core power. (That's the best I could do on my Infuse without causing stability issues.) Won't affect display or peripheral power usage.
[AT&T Samsung Galaxy S II SGH-I777] SNadler:
Using your kernel's on both the infuse and the S2 which do you feel has the better battery life under average daily use at work? Mine should be here tomorrow or Thursday and I am reading up on it... :)
[AT&T Samsung Galaxy S II SGH-I777] TheTodFather:
entropy, i'm really digging the experimental kernel with oc and updated linux kernel. Thanks a lot. I have 0 problems, phone is always cool. Very stable...
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
They're about the same - GS2 might actually be slightly better with the battery.

I originally thought the dual-core would cause fundamentally higher drain, but Samsung's dual-core implementation can fully power off the second core when not needed, unlike Tegra, where if one core's on they're both on.

What I'm thinking of next once people have beaten on 10/9 Experimental for a few more days is to pull in some nice patches from arighi that improve management of the second core.

I may eventually put in GPU OC once everything else is rock solid stable. However I worry about putting too many "at the user's own risk" features until I've figured out how to get ramconsole working. I kept forgetting to pick up a 150k resistor for UART mode at my local electronics store, then I remembered that didn't matter as they haven't reopened after last month's flooding. :(

Does it happen even if you disable OC/UV?

Easy enough to flash a different kernel (such as an older non-OC one) to test even if it happens with OC/UV fully disabled.

And what do you mean by "lower" both in SoC percentage and absolute battery voltage?
[AT&T Samsung Galaxy S II SGH-I777] Freddy2Fred:
I installed the experimental kernel and I OC to 1.6 Ghz with out a problem. I get a quadrant score of 4955. Now did I also overclock the GPU as well by overclocking the CPU?
[AT&T Samsung Galaxy S II SGH-I777] mjgspr95:
I flashed noname and seems to have fixed the problem ... I think going from stock to deodexed to cog and having SU problems along with other crap I've flashed just left remnants that caused issues.

It's going to be very minimal - And I may do it as part of a high-level tutorial that I always was going to do. (High-level meaning that anyone following it should be fairly comfortable navigating the Linux commandline and creating directories/extracting archives and such.)

It will be basically:

Deodex and fix problems in the deodex process

Remove bloat

Add Hellraiser

I may keep JKay separate.

That'll be it - after that I won't be doing anything more because I'm happy with it the way it is, unless someone finds a nasty bug that I can find a fix for. :)

Gestures

Sorry if this question is out of place for this forum. I've been searching through the forums and Google, and haven't got any luck. I just wanna make sure is not kernel related. Is there an app or mod that allows to skip songs from any app and any screen with gestures, maybe like setting up swype gestures right on the bottom of the screeen to skip or pause music.

An example of a good situation is that google maps doesn't give the option to skip song within the app, and the only option would be by exit out the google maps, open the actual running music app and then perform the desired action. Is pretty inconvenient while driving. Any help or suggestions would be appreciated it. Thanks again.

What's wrong with XWLA4 over XWKL1? or just not as much test time on it?

@ ****x76 - If it seems like the wrong place to post a question that has nothing to do with the thread it probably is...instead of being a **** some more I can tell you that PowerAmp has some shake to skip apps....I don't use them so idk if they're legit or not but its a start.
[AT&T Samsung Galaxy S II SGH-I777] kikex76:
I was just wondering if is something that can be done kernel wise. I think Poweramp only works with Poweramp. I was wondering if there is something you can use with any music app like pandora on any screen. Thanks for the suggestion brow.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
That's 100% userspace (system or applications), definitively not kernel.

Well it COULD be done in the kernel but this would be a craptacularly bad way to do it! (Basically putting userland code that has no business being in the kernel into the kernel.)

I've been running XWKL1 for two weeks, XWLA4 is too new. When I started playing with XWKL1, LA4 was not supported by JKay.

I may drop a release then play with LA4. This is getting offtopic for a kernel thread though - just wait a few days and there should be a more on-topic thread. :)
[AT&T Samsung Galaxy S II SGH-I777] stone_ship:
Sorry Entropy, I know this is off topic but I can't resist:

Have you been able to get as good battery life with your kernel on XWKL1? I have been on Hyperdroid KL1 final for 2 weeks, and have not been able to hit 5 hrs screen-on time with a single charge, which was pretty much guaranteed with UCKH7. Everything else--BetterBattery, CPUspy, Wireshark--shows nothing abnormal. Could be just my usage has changed....
[AT&T Samsung Galaxy S II SGH-I777] tedkunich:
I would think that Tasker would be suited to do this.

T
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I have had excellent battery life on XWKL1, it fixed some small drain issues that happened when combining my kernel with XXKI3.

However I don't pay attention to screen-on time as a battery life metric because it simply has too many variables - brightness levels, usage patterns (web browsing will use much less battery than a 2D game like Parallel Kingdom, which will use less than a 3D game, and hardware accelerated video decoding is fairly battery efficient even if AFTR idle gets blocked, since the CPU sits at fairly low clock speeds.).

I generally focus on reducing baseline idle drain as much as possible - this saves juice for when you need it. XWKL1 + later DD releases is the first combo to achieve less than 1%/hour at my desk (which is a horrible weak-signal scenario), and gets close to 0.5%/hour when connected to my home wifi. XXKI3 had issues where it would hit 2%/hour on my home wifi despite no obvious deep sleep/wakelock impact - it seems like some wifi feature got "stuck on".
[AT&T Samsung Galaxy S II SGH-I777] stone_ship:
Thanks. You're probably right about screen on time. Too many variables.

Anyway, I would love to try out your pile of poo ROM or whatever you decide to call it. Since you are consistently diligent in documenting your steps, there are many of us who would love to learn the process from you.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
This has been my experience as well. On KL1 and your 1/30 and 2/7(on this one now) weak signal drain is the best I've seen(<1%/hr). Better than what I was seeing with VillainROM(KI3). At home on my wifi network drain is extremely minimal. For example, the other night went to bed at 10pm with wifi on, battery at 89%, woke up 630am with battery at 85%, thats 4% drain in roughly 8hrs. I'm extremely happy with that, to say the least!

Thanks Entropy, for never being satisfied or complacent with your kernel and always looking for ways to improve it.(I think I can speak for most/if not all of us in the I777 community, when I say we're lucky to have you here in I777 land :))

I'm not sure what router you have for Uverse, but if it's a 2-Wire 3800HGV-B then you most certainly can use a proper wireless router behind it. I've got a Cisco E4200 running Tomato behind my 2-Wire and it works flawlessly; the 3800 is simply acting as a modem and the E4200 handles all routing duties. I also used to have an old Buffalo running DD-WRT in the same way.

PM me (or point me to the thread where people decided that it wasn't possible to do with Uverse) if you have the same 2-Wire gateway and need details on how to set it up. It's very easy to do.

Hey all, have a few newbish questions. First off, I'm running UnNamed 2.2.1. Up until recently I was running the included DD 12/08 kernel. I'm having some intermittent bt connectivity issues. Seems like about 1/3 of the time it won't connect to my in car bt (Acura HandsFreeLink.) Also have problems connecting to my headphones (Sony MW-600) and my laptop. When I was trying to pair it with the laptop, I had the bt radio on and had the phone visible. The laptop could see my printer, but the phone didn't show up on the list. Cycling the bt radio off and on didn't help. Rebooting the phone didn't either. It just eventually showed up. Same thing seems to happen in the car. I didn't have the issues when running the stock firmware. I updated to DD 2/07 and the issue persisted. If anything, it was worse. Earlier today I updated to DD 2/15C. Should that solve the issue?

How much effect does kernel have on data speed? The speed test app used to show around 2.5 - 3 on average. When I updated to DD 2/07 it went to anywhere from 7 - 9. Upload speed was unchanged. And I am seeing a definite difference in web browsing and app update speed.

Third, with all the issues associated with KK6 is there anything keeping me on that radio? Can I switch to a different radio on the same ROM and kernel without issue? Thanks!

+1 for Sh!tRom
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Nothing in 2/15 should be an improvement over 2/7 Bluetooth-wise - sounds like most of your issues are specific to Unnamed 2.x regardless of kernel, which is not surprising considering how many known issues are present in the UCKK6 system base with wifi and Bluetooth. (WIFI and BT are handled by the same chip).

In fact 2/15 consists mostly of reverting a bunch of patches out of 2/7 to figure out which one caused stability issues for some, and some fixes for clock speeds that were likely the cause of some of the 2/7 stability issues.

Compared to a stock kernel, the initramfs in this kernel could affect data speeds - I changed the TCP buffer size values to match the Infuse. (I think the UCKK6 kernel has most of the same changes.)

Modem and system/kernel are fairly independent of each other. Some people think UCKK6 modem is better, some think UCKH7 works better. At first I though UCKK6 was better, the second time I tried it, it performed poorly at work, but now that I'm back on UCKH7 modem and it still performs poorly, I think something just changed with the local tower.

To fix wifi and BT issues I recommend trying a firmware not based on the UCKK6 system image.

While the BT chip's driver is in the kernel, there are a bunch of userspace support utilities including the chip firmware in the system image - it seems like everything related to wifi/BT support in the UCKK6 system image is kinda broken.

Not much use, about 1.5hr on calls, 2 hr display, which included about 40 texts, some google maps for getting directions, some web browsing, and a few tweets. Very little usage for the amount of time. But in my history I've never gone 2 days without charghing, on any phone or device, and I've had a few ;)

the last 24 min or so was a phone call, ended at 1% battery. Had 7% about 9 hours ago

[AT&T Samsung Galaxy S II SGH-I777] UGART3:
I have been using the 2/15 C for over 24 hours now I can I say I have seen a significant decrease in battery life coming from Siyah on ICScrewed. After about 7 hours of very minimal use I would see about 17% drain and today after being fully charged this morning and exact same usage I saw 46% drain. Just an FYI for those who are more concerned about the actual performance as opposed to ****ty ROM names (semi-serious sarcasm)
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
This is very unusual - NOT consistent with the results I get.

More details - any unusual wakelocks, anything unusual in battery statistics?

The only power management problem I've seen of significance is that on XXKI3, idle drain could go up to 2%/hour since I updated to I9100 update3 - but that would not explain what happened to you, since I have never seen that behavior on an XWKL1 base.
