I've seen the page about governors, but can't seem to find anything about schedulers. Which scheduler is recommended to use?

I think it will a little bit help when you change the change log with the point that touch control no longer will work at the moment, every three posts the same question sucks.

If you think no need it's ok but I think it helps the one or other :)

If you will you can take my short how to that I post a few posts before ( touch wake ) for a faq post.

Otherwise 9.0 works fine for me, no bugs found at the moment.

any suggestions for the tcp, io, governor as well as the color settings?

i m using lg color preset....do i need to change the amp to make it even better?

I'm currently using 15, 15, 5; 0, 0, 0 for amp.

100% removes the yellow tint (better known as urine filter), and makes the colours less washed out. Try it, look at a white screen and you'll understand what I mean.

OTG, thanks mathkid, otg was the missing part of the jigsaw for me.

Only problem now is I have no idea which of the latest version I need to download.

I usually swap between carbon, rasbean & xenon.

Pls help, cheers

Ok guys, poll is up!
[Nexus 4 Original Android Development] playya:
Putting it on the first page as a changelog or in the post above you won't matter to most if they are too lazy to read... Unfortunately xda has a lot of those types of people.

For those that care 9.0 runs just as smooth as 8.5 if not better, I had some emails some text used some wifi tethering (not much) and just checked my battery and its at 91 after 5 hrs 45 mins of running. This is also with adding the "fix" posted earlier for receiving notifications over wifi. All is working fine....

LiquidSmooth Matr1x kernel(s) = no problems

In the change log it said OTG in v9 : (. Yehi know what it is and was using ziddey/franko rim with my y-cable and 5v powerpack.

If there's no otg with new matrix, any idea (besides Franko based kernel that has OTG capability. I miss being able to keep a ton of rims and kernels on flash disk : (

'Rims' being 'ROMs' lol. Thank you auto correct

---------- Post added at 06:56 PM ---------- Previous post was at 06:21 PM ----------

v9.0 Added USB OTG by ziddey, updated the FauxSound to v2.1, added the idle drain patches, updated the ROW I/O Scheduler to the latest version, added Touch Wake by stratosk, and got rid of the touch_boost errors in the logcat.

Where is the the OTG bit?, I used to get to ziddeys through storage in settings.

Used to say 'mount usb device', days bugger all in matrix v9 wtf? : (

Strictly as an fyi - but the first line of the Carbon rom thread reads "CarbonRom is an aftermarket firmware based on the Android Open Source Project" - generally if it was a CM based rom most developers will let you know at that point. Also the "search the thread" feature within this thread would of pulled up a previous discussion of what kernel to use in the same situation by simply typing "carbon". I believe the user in that discussion actually used the cm version and preferred it. Feel free to go back and check or even PM them to see their results. You may have multiple choices :D

If you shut off the screen with the power button nothing will happen, let the screen timeout and it should work.

Thanks. I've never used touch awake before. Seems like it works great
[Nexus 4 Original Android Development] alen1901:
You know what in trickster app "seconds to delay" means in touchwake? If i set it to zero, touchwake works, if i set it to 5 or 40seconds, it doesnt work. Also, there isnt option to set touchwake time out, maybe on semaphore app?

EDIT: nevermind, that IS timeout option. Somehow it didnt work at first, now all is ok.

You have to download "touch control" app from the play store.

The only kernels that have native s2w are faux, showp, and.... one other. There is a problem with those though. Read the threads

There is a problem with showp s2w. It's not as stable. Read the threads, I don't the technical lingo.

I know sometimes you have to tap the screen first, before you can slide. And I think there is another bug as well. But I don't want to comment without knowing for sure.

Show says s2w version 2 is coming but he didn't say when.

Same here, +25mV and the lag on wake up lockscreen disappeared ;)

I think below 200mhz and 100mV UV is pretty tight, maybe not stable over all for every one.

Im more than happy with the version in this kernel as its a new feature for me....and i love it :good:
[Nexus 4 Original Android Development] krispycorn:
Have same exact issue and a friend as well. Won't charge in car, charges in the house. Went back to 8.5 and it charges fine. Curious what the cause is.

Carbonrom's battery icon shows charging, but in System Settings > Battery it shows Not Charging and battery drains like nobody's business with typical gps/BT car usage (obviously).

[Nexus 4 Original Android Development] soumoks:
I have noticed that the CPU tends to stay at the max frequency a lot,is this because of the lowered min frequency? What frequencies are you guys using with this kernel?also this kernel comes UV by 100mv by default,is this ok for my phone?have a nominal CPU..TIA :)
[Nexus 4 Original Android Development] jiayit:
To answer your 2nd question.. Each phone handles UVing differently. I have a fast CPU but it can't even handle -50. Some others here have a nominal one and can handle -100. So if things start going wonky, your phone starts rebooting and whatnot then just increase the voltages :)
[Nexus 4 Original Android Development] tkgod:
The only reasons your CPU would do that is either MP decision is enabled or the Wheatley governor is active. Either is normal. Ondemand will do that too if it's under a lot of load.
[Nexus 4 Original Android Development] soumoks:
Thanks both of you!

the phone seems to run fine with the default undervolt,so will keep it at that..

the governor was at ondemand,so got the answer..

one more question,if the min frequency is set at 192 MHz ,is it an advantage or a disadvantage?when we open any app,it never uses the min frequency instead jumps to a higher frequency,so it will be helpful if the min frequency is set a little bit higher :p.hope you guys got my doubt..

[Nexus 4 Original Android Development] sirxdroid:
It's questionable whether frequencies under 384 Mhz are really used at all, in spite of what the sysfs might report. There were some tests done in the _m+ kernel thread and the conclusion was they were not used. Also, show-p1984 who develops the Bricked kernel showed that he could "run" even at 27 Mhz :) You can make the kernel report whatever via sysfs, but you'd actually have to open up the phone and measure the frequency to be confident it's running at the reported number. Same with the voltages, it was discovered that in some kernels there was a missing patch that prevented the voltages from being lowered, even though they were reported lower so some people were claiming they could run 1.5Ghz @ 600mV when in fact the stock voltage was being used instead.
[Nexus 4 Original Android Development] alen1901:
192mhz is used on idle with screen on too. If you dont touch anything. Ofcourse MHz will oscilate but it will use 192mhz. Use perf monitor to see that.
