Well, without any sort of kernel log/logcat of any type, it's anyone's guess...
Reflash the ROM only and run that for a couple of days before flashing another kernel, or try another ROM altogether.

Hm, can u say to ms, how i can make a log?

You'll probably want to pull a dmesg log and/or kmsg log, I've never done that but here's how you can pull that info: http://forum.xda-developers.com/showthread.php?t=1520508
At that point, if you get these, you'll want to send them to the ROM and kernel developers of the ROM/kernel you're using to see what they see in those outputs.

Do you have the 8 or 16 GB? Apparently the 16 has issues when it's nearly full. I'd say wipe the caches and see if it gets better. Are you stock or running a custom rom? Stock or custom kernel?
16 and on stock

Mine's that way too... almost unusable, it was almost full, now with 6gb free...
Stock 16gb
I was having something like this happening about a month ago. I took that time to consider rooting and it's never been better.

I've never used any nexus I own without rooting
And AFAIK, rooting doesn't change the speed of the device, just gives you root powers to alter something, that MAY alter the speed!

Why does this thing lock up all the time?

This device is blazing fast most of the time, but it will inexplicably lock up, completely, for a few minutes at a time for seemingly no reason. Right now it's frozen on a youtube video and I can't turn it off or use the screen. The device is also unusable really when installing apps, and will lag heavily in Google Now sometimes.
Is this just me? Or 4.2.1?
Just you. My N7 is still operating at warp speed and doesn't lock up..

Are you stock? If so I heard people saying turning off the sync for currents will help, for Google now lag I feel its performs better if you turn off the hot word in setting. But with that you can't say Google and start voice search
Sent from my Nexus 7 using Tapatalk 2
I'm stock 4.2.1 and don't have those issues. I do have currents (and various other apps) disabled, so like previous response said try that. Otherwise maybe go with a factory reset.
When my gnex updated to 4.2 it's performance suffered until I factory reset, now it's been much better.
Sent from my Galaxy Nexus using xda premium
My best guess would be you have installed an app that is not compatible with 4.2.
How about posting a list of what you have installed, if you use multi-user, and if you are stock (not rooted), and we can give comments.
I agree. I'm running PA and rock solid. I was also rock solid on stock.
I've never had it lock up. I flashed a Trinity kernel once that caused sleep of death... but it was a known issue.

I have a pretty decent amount of apps installed. I'll post them in a minute, but no, I'm not multi-user, and I'm stock. I'll root and put a new rom on this thing if it's worth it, I figured it'd be fine the way it came.
btw, here are my androbench results. Are these slow?

These are what I disable.

thanks, I'll try disabling those.
Over 100 apps in total, my andronbench write speed is clearly an error so just compare read and app open macros.
My apps open much faster than yours, which I'd put down to PA ROM and kernel. Maybe your write speed is a bit slow?
Can you download "forever gone" from market and try a full fill and delete? Apparently helps reset the memory controller to improve performance.

Nexus 4 aokp sound not working

Hey so I've been running aokp for a few days now, and suddenly I noticed that the sound isn't working, not for notifications, not for music, videos, anything. Not even when the headset is plugged in. So I flashed my stock Rom backup and it still isn't working, any ideas?? Thanks!
Sent from my Nexus 4 using xda app-developers app
Ok this is weird, sound just started working on my stock Rom. Haven't tried aokp yet, the restore backup of stock Rom took 30 minutes and I need to sleep soon so I don't want to risk hanging to stay awake for it, it normally takes 3 minutes to restore backups though, idk what's wrong

I'm having a pretty same problem here, the only difference is that I'm running Paranoid Android on my Nexus 4. Do you find any solution yet?

Slow Nexus 7..

For some reason my Nexus 7 is strangely slow lately idk why, but I want to know if anyone else has seen there Nexus 7 lagging? And if anyone knows how to speed it up? Posting screen shot of my system info.

Exactly the same here. Typing's hard work, and tapping icons or buttons can take a couple of tries before it registers. All updated and tried a reboot.
You should upgade to 4.2.2, make full wipe and start from scratch. Then you will see if lag is still there.

Try lagfix(fstrim) anyway it free and took only a few seconds to finish it's job. Even you're already have more than 5 GB free but in the old kernel seem to have a problem with nand flash controller.

[Q] Nexus 10 running like a slug

My Nexus 10 has started running like a slug at times. Rebooting does not help. Last night I upgraded to 4.3 and it still seems to be an issue. This device is stock.
Any suggestions?
Try a custom ROM or kernel. Or both. You can always go back..

It worked fine up until last week. Then it would go through spells of slugginess. I would reboot, and it would seem fine for about 10 minutes and get sluggy again. I figured it was an app action up and I was going to set it on born on date and start all over. I put the 4.3 on it thinking that might help, but it still had issues. The next day, all was fine. It has only been two days of working fine, so who knows, but i am happy again.
Looking at some posts in this thread, I will assume that you are not happy with yours and have been very vocal about it.
What are your issues?
you name it ...
i am waiting for Sabermod 4.3 ... they could make this more acceptable , again
