R64 is still running like crap here, back to r62 and all is perfect again. I can't work it out!
[Nexus 7 Original Development] franciscofranco:
Hmm, can you do a nandroid, flash stock rom, and see if its ok? Works just fine here on stock rom.
[Nexus 7 Original Development] sjknight413:
Yeah I'll give it a go a bit later, where would I go about finding a zip of stock 4.2.2?
[Nexus 7 Original Development] jfmcbrayer:
https://developers.google.com/android/nexus/images, though they're not zips -- you'll have to use fastboot to flash (as far as I know).

So, I'm sure this isn't a one kernel vs another kernel issue, more likely a launcher vs RAM issue but I'm hoping maybe someone can maybe help me with a governor/IO setup that can help: My N7 and N4 have nearly identical setups/apps etc... anyway, using Nova launcher heavily... on boot, N4 is fine, N7 takes like 1 minute after initial lock screen to load status bar and nav bar. AOKP. Any tunable ideas? Thanks
[Nexus 7 Original Development] Taxiback:
I have an N4 & N7, both stock roms, both running the latest franco kernel and to me the N7 seems faster at everything..!

[Nexus 7 Original Development] c0manche:
How does keeping 2 core affect the companion core?

I thought maybe wrongly that the companion core only operated when freq was bellow 400Mhz and only 1 core was in use!

Just a question sorry if I am been an idiot
[Nexus 7 Original Development] Kaiyes:
I was able to recreate the torrent-overnight charging-deep sleep-hard reboot issue with r64 & multirom with pa 3.15 as internal. Here is the last_kmsg.
[Nexus 7 Original Development] qu3becker:
Franco disabled the companion core since it's isn't a real core and switching from the "companion core" to actual core took more battery anyway. If I understood correctly.
[Nexus 7 Original Development] konradsa:
R64 is great, just as smooth as the previous versions. Also noticed the cpu frequency seems a lot less jumpy now. For instance, monitoring the cpu frequency in trickster, it doesn't jump around anymore continuously been 200 and 1300.
[Nexus 7 Original Development] The Gingerbread Man:
OK so from my limited abilities there was some stuff to do with GPU in that log, do you over clock it? Also I can't read that log in full as root explorer gives an error about file being to large. Could you post that log to pastie.org and link again
[Nexus 7 Original Development] The Gingerbread Man:
I'm probably going to curse myself for this but *touch wood* battery on r64 is looking to be very good. 45 mins off charger, 43 mins screen on time
[Nexus 7 Original Development] fgenari:
I know this will sound a bit stupid .... but after many, many tests, I came to a conclusion.

The problem is not Franco Kernel + Cm10.1

But the trebuchet of cm10.1

I tested with some other launchers (Nova and Apex) and the small lag that appeared after the R63 and R64 disappeared.

I pray that whoever is using Cm10.1 and reporting problems, test some other launcher.

I'm not a developer, just a user .... So all this can be really stupid. But I thought I should share with you all.

Maybe a small thing can lead to other conclusions.

I apologize if I spoke just nonsense things.

I love Cyaongenmod and Franco(gnex, n4 and n7 combo) then I am seeking some solution....

Cheers!!
[Nexus 7 Original Development] osm0sis:
Hmm maybe trebuchet doesn't like being reniced?

When you're noticing the lags, in Terminal Emulator type "su", grant root, then try: renice 0 `busybox pgrep com.cyanogenmod.trebuchet`

Let me know if that resolves it (should be instant). You could also try values of -10, or -21 to see if they make a difference.

Edit: Note that if you didn't have any problems with r61-osmod that basically rules the above out as being the current issue, but might as well try other niceness values anyway.

P.S. r64 seems to fix the touch issues I was seeing in Chrome, especially on pinches.
[Nexus 7 Original Development] nuchdog:
This has been going on for a while. Try it in portrait mode. For some reason, when the app is in landscape mode, the popup download status/progress window doesn't appear and it causes a force close when you try to auto flash or down load a zip.
[Nexus 7 Original Development] :
This was in portrait mode, so I don't know what's the problem.
[Nexus 7 Original Development] GedBlake:
And for what it's worth - there is a warning...

Running franco.Kernel updater v10.0.5 - Having selected the franco.Kernel Updater option for the latest kernel, I received this 'toast' message whilst in lanscape...

"Your device is in Landscape mode, please change to Portrait before downloading to prevent unwanted Force Close due to Activity being destroyed."

[MENTION=4860695]jasperjoey[/MENTION] There were quite a few force closure issues with earlier versions of v10, but I think these have now largely been resolved. Certainly I have no problems myself... (whilst in portrait).

Have you tried clearing data in SETTINGS>APPS>ALL>Franco.Kernel updater? Might be worth a shot.

The most safe and stable is the default stock value!

The next values are 484 & 520.

[Nexus 7 Original Development] !crazy:
Just try your self, not every chip is same. I am using 546 (currently) and sometimes over 600 (but not Franco's kernel, because there is no option to over volt.) and never had any problems
[Nexus 7 Original Development] Fobz:
I have to say that the latest r64 feels abit faster than r63. Most noticeable when opening app drawer on nova.

Thanks for the amazing kernel!!
[Nexus 7 Original Development] gtizon:
No issues running r64.
[Nexus 7 Original Development] l3s:
My battery draining little bit faster, and also have low charging speed. Sometimes when I plug the charging cable not changing, I have to connect again.

Anyway, this is the smoothest kernel for N7.

Anybody that is smarter than I am read this? I haven't noticed it on my tablet yet. They talked about it on the most recent all about android podcast as well. http://androidandme.com/2013/06/opi...from-the-best-to-worst-tablet-ive-ever-owned/
[Nexus 7 Original Development] lollyjay:
All I can say is that I've had my 32 gb since first introduction, and experienced NOTHING like described in the post. It really disturbs me when people use limited experience and knowledge and make blanket statements denigrating a person/place/object.

EDIT:

" I can’t find one person who has been using the Nexus 7 for an extended period of time, and hasn’t seen a massive downgrade in performance."

Thanks for pointing this out.

[Nexus 7 Original Development] qu3becker:
Yeh, read that today too.

I did notice a noticeable lag on my 16GB N7 but once I runned LagFix it all disappeared.

What I understand is that ASUS cheaped out on the flash memory module because the Nexus 7 is not the only device slowing down (according to some users) after some usage/full internal memory. Many ASUS android tablet have the same problem.

You might try Forever Gone (SD Card Cleaner) if you have any of those issue too. Both tools are temporary workaround.

The title is sensationalist bullcrap, though. I'm sure the first iPads with some of the last updates it had has terrible performance by now.
[Nexus 7 Original Development] jlvlawrence:
I've only had mine for about 8 or so months. One of the guys on the AAA podcast was complaining about his gnex slowing down as well. I haven't noticed it on mine either. My next question is would this affect people that are changing ROMs frequently. Sorry about getting of topic@ Franco. R64 is running like a boss on my 7.
[Nexus 7 Original Development] Kaiyes:
Thanks for taking interest, I really appropriate this. However I have the same problem as you. Can't open the file fully. Root explorer is giving me the same error message. I didn't touch anything in r64. I almost never over clock my GPU.
[Nexus 7 Original Development] GedBlake:
Yes, I read that article too... it's referenced over at

Digital Spy Forums - thoughts on nexus 7

, where it's sparked a bit of a debate.

I'm not sure if the author of the article is being deliberately contentious or not... but I've had my Nexus 7 since November, and I ran it for several weeks, stock unrooted, before I got involved in the business of flashing custom ROMs/kernels. And I do not recognize the authors experience... Quote:

"I can’t find one person who has been using the Nexus 7 for an extended period of time, and hasn’t seen a massive downgrade in performance. Just what kind of downgrade are we talking here? I cannot pick up my Nexus 7 without experiencing problems like a lag of ten seconds, or more, just to rotate the display; touches refusing to acknowledged; stuttering notification panel actions; and unresponsive apps."

Maybe he had a faulty tablet... or a lack of technical knowledge to remedy the problems. Whatever the reason, I wholeheartedly disagree with him.

Anyway... just my thoughts.

Rgrds,

Ged.
[Nexus 7 Original Development] osm0sis:
My best guess is he got a chip that doesn't discard, so he needs to run fstrim/Lag Fix.
[Nexus 7 Original Development] slebit:
R64 is running nice for me, it's really smooth.
[Nexus 7 Original Development] khaytsus:
Every 16G owner, unless they changed chips at some point. Although he claims that he's done a factory reset and it didn't help. He doesn't say he didn't restore everything back and fill it again etc, so we don't know if it was still slow "out of box" right after his factory reset, etc..

The 16G chip does need discard/fstrim, and does get slower as it fills. But if it's not full and it's properly trimmed it's no worse than it was to start with.

The whole article repeatedly implies that flash storage gets slower as it ages/is used, basically. That I've never heard of.

That said; I do Forever Gone about monthly, and own the fstrim app to do nightly fstrims on a schedule. It minimizes the erase lag of the 16G chip anyway. I still think the storage is crap in the 16G model of the Nexus 7. But as for "wear and tear", no.
[Nexus 7 Original Development] konradsa:
While I love r64 for performance, battery life is worse thn r47. GSAM lists average battery life of 9h 30m, while on r47 it was always between 10h 0m and 10h 30m.

Franco, any clue why that could be? Is it due to the undervolting not working anymore, so even your default undervolt over stock is not active anymore in r64?
[Nexus 7 Original Development] TheByteSmasher:
That happens to me too. Only on Franco's kernels though. When I wanna torrent I have to reboot with lean kernel or something... :(
[Nexus 7 Original Development] lollyjay:
Should say that even though your battery life is worse, not a general problem as far as I know. Mine is same or even slightly better on r64. Possible that you have something running that consumes battery? If you revert back to r47, does battery life instantly improve? I tried this and noticed no difference, or even slightly worse than r64. Personally I'm confused as to how to get a definitive handle on it. Is there a good battery benchmark test?

Just had a major slowdown while browsing with chrome, from system monitor it looked like the processor was locked to 204mhz during the slowdown period then it came back normal.
[Nexus 7 Original Development] Shano56:
Logcat?
[Nexus 7 Original Development] combatdeity:
Had a freeze today when opening chrome and reloading a bunch of tabs. Had to hold down the power button.

Would this show up in kmsg?
[Nexus 7 Original Development] osm0sis:
No. Because you held down the power button. :(

/proc/last_kmsg isn't useful in these situations because it only gets recreated after a soft (sudden/automatic or menu-triggered) reboot. Holding the power button down is equivalent to a battery pull so it doesn't provide a new last_kmsg.

For something where you have to hard reboot (power button), you have to copy /proc/kmsg before rebooting to provide anything useful. A logcat or dmesg before rebooting could also help.

[Nexus 7 Original Development] Shmi117:
If battery life is worse why not just change some of the kernel values? I've UC'd to 1000 with 760 as my high speed load. I've also raised the hotplug value to online all cores to 90 instead of 60. I have great battery life and smooth performance.
[Nexus 7 Original Development] konradsa:
True, but would be nice to have the cake and eat it too! :D But the only way I can think of getting longer battery life now without giving up performance is undervolting, but as I understand that is broken in the latest builds.
[Nexus 7 Original Development] Twau:
Great to see the nexus 7 getting some love :) r62 seems a bit smoother on my device, I notice a slight difference when I scroll down in G+/Falcon pro for example. I am running stock rom. Guess it's a derp on my device, cause I've not seen anyone else mention this.

Got a strange bug using r64.. The first time happening for me...

[Nexus 7 Original Development] franciscofranco:
Companion core is bull****, never seen any real battery improvements from it. And the Kernel driver that gives awareness for cluster switching is something so half assed and weird coding that sometimes I wonder how the device even operates.

Thats been fixed on my local build. Newest beta apk also has that fixed.

Those apps only run algorithms based on history, I wouldn't give them any real credit for battery prediction other than being informative. Best thing you can do is just enjoy your tablet and not paying attention to those apps other than general information.

--------

Few things though.

1 - I don't know whats that torrent bug. Seems like somehow related to some IO patch, but I don't know what it is unfortunately. I'm hoping that 4.3 comes fast because I want to rebase and start over fresh.

2 - I didn't feel r64 wastes more battery than the others. But you're also free to increase the Hotplug driver first_level threshold to 80 or 90 to prevent cores to go online as much. You can also decrease input_boost_freq and hispeed_freq to 760MHz.

I have other tricks up my sleeve though. We'll see what goes in the next days. N10 and the new app update will have priority because I want things to be great before I go to vacation in about 20 days.

Thanks everyone for all the feedbacks!

[Nexus 7 Original Development] !crazy:
I was getting the same issue with my GN back then. After a while device was getting slower and slower. Full factory reset, formating everything would 'fix' that. And yes I was flashing like a crasy, and was using the device a lot.

Regarding N7 I don't have any problems, it is very fast (But I tune it more for performance, not interessted in sacrificing performance for 15 m more battery gain.), but I got a new N7 a couple of month ago (so new memory, but don't rember I had any such problems with our old N7), because my son broke the screen of our first N7. And while we use the device its flash memory is not very stressed I think. We usually stream videos for my son, and I am having fun here and there by playing most wanted or similar. So no torrents, or similar.

Which driver from r62?
[Nexus 7 Original Development] Gspin96:
LOL removed touchscreen driver. How can the touchscreen work then? That's black magic!:laugh:

I'm running r64 perfect here, although I had high screen-off battery drain I think. Now charged full and see how this goes, maybe I've some battery-killer-apps ;)
[Nexus 7 Original Development] irminsul:
How's the touchscreen working for you? With r64 I can't use my n7 when using my thumb, it doesn't recognize the touches or makes a click in stead of a swipe. The overall response of the screen feels a little worse compared to r62.
[Nexus 7 Original Development] Timo_SGS2:
Tried to reproduce your issue, but it seems i am not able too.

tried it in landscade and portrait mode, no issues...
[Nexus 7 Original Development] why always me:
Try it by your self then, like scrolling though setting page or facebook newsfeed with the same amount of pressure and distant and see what is the different.

Maybe it's just me but with r999v1, r999v2 and r62 when i'm changing direction of scroll instantly like swipe from scrolling down to scrolling up the touchscreen respond properly it not stop scrolling it just change direction.

But with r63, r64 and all other kernels when you've swipe your finger to change scroll direction it stop scrolling so you've have to swipe your finger to the direction you want again.

And yes the touchscreen its little more responsive in r999 and r62.

And sorry for my mistake the word remove I mean he convert back from that unique driver in those build (Remove) to stock driver not mean he completely remove the driver.
[Nexus 7 Original Development] Gspin96:
How do you use the tablet?

It's known that the nexus 7 has some grounding issues. Since the capacitive touchscreen works because of the electrons moving between your finger and the screen, the screen has to be well-grounded. On nexus 7, if you aren't holding the tab in one hand, it's possible that grounding can be insufficient to get correctly more than one touch.

Here is a video from a random guy on youtube: http://www.youtube.com/watch?v=Cd2xtIxhEBA&feature=plcp

EDIT: [MENTION=5239262]why always me[/MENTION]: i tried scrolling, then turning back. Even if i make rapid circles (or ovals) the page scrolls correctly following my finger, so I can't reproduce your problem. I don't understand the "same amount of pressure and distant" thing. If you talk about screen reacting from distance, then touchscreen=you have to touch it, it's not meant for distance interaction. If instead you talk about very-low-pressure touches, then I can say that my nexus 7 registers them correctly.
[Nexus 7 Original Development] mpokwsths:
R64 is pretty good. But r62 is the most responsive kernel I have every used. The first time I use my N7 without having erratic touchscreen behavior at all. There is definitely an impact of the active cores and/or frequency to the touchscreen behavior...
[Nexus 7 Original Development] bsoplinger:
Same here, completely frozen with no chance of pulling a logfile. Dropping back to r62 for now. Only info that I can provide is that the error happens when I'm letting it sleep while using the Audible app over Bluetooth. If it sleeps without me using Audible but still with Bluetooth audio I'm fine.

[Nexus 7 Original Development] franciscofranco:
I'm starting to think there is some kind of problem with the Nexus 7 itself, theres so many issues that I've seen listed across the web from people even using stock rom/kernel that I can't really differentiate between some possible derp from me or a real derp from Google, specially because logs don't show any error as far as I can tell. I might just start from scratch again from a clean Kernel state and build it up again from there.
[Nexus 7 Original Development] nexusmaniac:
That sounds like a good idea because even with 4.3 around the corner I don't think that Google will fix any of the nexus 7 problems so building up your kernel from scratch would make the kernel even better than it already is :)
