There are just tons of ways to learn how to do this stuff.

As someone mentioned, there is an app in the playstore called log cat that will get you the log. You'll need to monitor the phone and try to capture when the data drop happens so you can get the log without having to sift through a ton of info because it's tracks lots of stuff.

If your phone gets a random reboot, when it powers on use a file explorer (i use root explorer) and go the base directory. From there go the to proc folder and look for the file names last_kmsg. Copy that file and past it into your normal SD card. You can move it to your computer, zip the file, and upload it to the post. This is one way of doing it, but there are also many others.

---------- Post added at 10:32 AM ---------- Previous post was at 10:31 AM ----------

Not even 2 pages back franco said it's pointless to post the info unless the proper info is provided. I explained how to do it, but as soon as it's 1 page old people will come on asking the same questions.
[Nexus 4 Original Android Development] nixie2121:
Thanks, you are correct, I should have searched first, I apologize.

Anyway,, The issue just happens and it can take some time, so I suppose the log would be giant as I would just have to start logging and then when it happens stop it, unless someone has a better solution.

Thanks for the help everyone, and I will do a better job searching first, my bad.
[Nexus 4 Original Android Development] PetritH:
But still, his question was how to post a log... anyway its pointless discussing that now.. and it will happen again and again... people are lazy too read these days
[Nexus 4 Original Android Development] Net.silb:
First of all, I'm pretty sure [MENTION=4928198]Arstoien[/MENTION] was referring to kernel releases, mistakenly calling them revisions...

Anyways, if you're already opening up the topic, I have a rev10 and I compared it to a friend's rev11 and I can confirm that the touch sensitivity is much better... :(

However, I fixed this by flashing the E015 touch driver that has much better sensitivity than the E027 driver. I know that in the past you said that the E015 driver has ghosting bugs but here is my theory:

E015 works best on rev10 devices and does not cause bugs on those devices, because their touch panel is less sensitive so the driver makes them more sensitive to touches. E027 on these devices lowers the sensitivity to touch, but becuase these panels are already not as sensitive, it makes their touch sensitivity not as good.

E027 works best on rev11 devices, but E015 raises the sensitivity to much for these panels and causes ghosting issues because they are already more sensitive to begin with.

What do you think of my theory?

Maybe, now that you have experienced bad sensitivity on your rev10, you can add an option in the kernel and in the app to use E015 as the default touch driver for us poor rev10 owners? :angel:

By the way, here's the thread for the touch sensitivity fix: http://xdaforums.com/showthread.php?t=2163924

THere is a thread here on xda that explains how to logcat like a pro. I use to have it bookmarked but I dont anymore. I do know it was titled "learn to logcat like a pro" so that should make it easy to find.

You are right the log will be huge if this is not happening real frequent plus with logs you need to edit out your personal info that pops up in it.

An update to my post below. I discovered last night that my wife had accidentally switched her 8MP camera to be taking 1.3MP shots. I switched mine to the same setting... and *poof* faster shutter. I was kicking myself for not figuring it out sooner. Sorry if I sent anyone on a goose chase. Thanks again to Franco for the awesome kernel.
[Nexus 4 Original Android Development] :
Problem is some noobs will flash that driver and come complaining in the thread and the tweaks Franco's done for sensitivity work great, why give additional options? Great idea though, I consider myself adventurous but even I've never tried those drivers, I don't see the point using downgraded drivers, I bought a Nexus cause I wanted to get away from ugly hacks (coming from the S2)

Hey all,

running 154 and it's pretty smooth. Checked my wakelocks and first time I've got this one "sns_async-ev-wakelock". Any one got an idea of what's causing this? Thanks! :)

Are you using Tasker?
[Nexus 4 Original Android Development] roilosh11:
No I don't have Tasker installed.
[Nexus 4 Original Android Development] hol17:
From what I've read, it is a magnetic sensor wakelock (which is why I asked about tasker). It won't be caused by the kernel, most likely an app or widget.

[Nexus 4 Original Android Development] steviewevie:
Rev 10 to rev 11 was just a motherboard change though. I wonder if those who are experiencing touch differences are just experiencing a coincidence? In all the threads discussing rev differences I have never seen lots of people saying there was a difference in touch sensitivity.

Similarly some people have claimed they have a better screen or whatever, but again the statistics don't seem to back this up.

Hi there,

Just to share, after 2-3 cycles of using and charging, no any suspicions of mine regarding more battery drain of FK r.154.- all default.

I mean - it is normal, it doesn't take more juice than usual

All is smooth, efficient.

The heaviest load I have when I watch a Flash stream from website (all 4 cores are on and at high load) - no issues,

I am with PA (latest before HALO)

The only "glitches" I ever had were while on FK r.148 I had first and only period of time 5-6 h with red line spots in battery stats for cell connectivity at home. (another phone has no signal lost - same provider H+/3G/2G fallback).

Now, all is good no complains :cool:

Thank you for the kernel and discussion here.

This is a very ignorant post... I'm on Tmobile and yes, they aren't known for best coverage. My signal was dropping in and out with r154 for several days, after reverting to r111 everything is back to normal. I'm sitting on the same chair where I had constant signal issues. Now signal is steady. Guess I just built three new towers around me, then :rolleyes:

Maybe it's an android problem but I haven't noticed that on stock but then again I didn't want to be on stock kernel for a long time.

Franco, not sure if you changed anything in that regard, but I think mobile data is better on r666 than r154. I had delays/timeouts on mobile data with 154 that don't happen in 666.

There's a chance to re-enable in some way wakestats for non-noob user? actually I find useful sometimes see what is draining and SEARCH ON GOOGLE FOR SOLUTION (all the time the drain is caused by app) or we can see app draining in another way?

[Nexus 4 Original Android Development] jasonwc:
It sounds like you're talking about manually flashing the OTA update in TWRP? This can be done. The conversation is about whether you can receive and successfully install an OTA update from within Android. And, everything I've seen suggests that the update will fail if you have a custom recovery.

As far as I have seen, OTA's update so long as none of the files it actually replaces are changed. So if it replaces recovery, you must have stock, if it replaces browserprovider.odex, it must be present etc...

After my first battery cycle with r22 (my first try of the franco kernel), I only got 3 hours of screen on time browsing with chrome on wifi and watching 25 minutes of imbedded video from a website in chrome. 3-4 hours is what I got with the stock kernel. So it's not too bad for a first try but I was hoping for a larger improvement. Do kernels usually need a couple cycles before improvements are seen? In one of the other kernel release threads, the developer mentioned a few cycles being needed before improvements are seen.

When people complain of battery drain, it's mostly caused by a wake lock, how are people supposed to figure out what app?
[Nexus 4 Original Android Development] franciscofranco:
Comon, its not hard... check the services running, check for apps with a bit higher CPU usage, googling a bit... its not rocket science.
[Nexus 4 Original Android Development] republitarian:
On the one hand I see your point. Numerous posts regarding wakelocks in this thread is a pain in the ass for u. On the other hand for users like myself who don't point to the kernel as being the culprit of wakelocks will have a little more difficult time to search for idle battery drain. Using the wake lock name on Google quickly points to sites that provide extensive information regarding the wake lock. Furthermore when installing numerous amounts of apps it will be difficult to differentiate what is causing idle battery drain. I pray this is not a permanent solution for the idiots on the forum.

Is 6666 the same as 155 with wakelocks being shown?

Kernel wakelocks won't be shown. Apps (Partial) wakelocks will be shown AFAIK.

OK fair enough. But, for me at least, I was having major msm_hsic_host "Kernel wakelock" (up to 22% on BBS and Android OS was on top of the list) when I was on your kernel in the higher 140s. This changed when you reverted back to different hsic in the 150s. Now my msm_hsic_host is 2%. Nevertheless a major kernel wake lock that was dramatically reducing my battery life. I guess if you don't change the hsic again this issue won't arise....
