4.4.2 (Advent) First Boot - Extremely Slow - Nvidia Tegra Note 7

I've just installed the 4.4.2 update on my Advent-branded Tegra Note and the first boot was painfully slow. The "Optimizing Apps" stage of the boot took more than an hour for 161 apps and when the boot was complete the device was lagging to a ridiculous degree. Swiping left or right on the home screen resulted in a jittery page change after maybe 6 or 7 seconds. I eventually had to force a shutdown. Subsequent boots have started OK but with periodic lag for 20-30 seconds at a time. Has anyone else had issues like this?

Oh, yeah. Got frustrated enough that I rooted it and downgraded back to 4.3... That said, try going into recovery (if you're not rooted) and clear the cache from there to see if that helps.

I have seen this randomly, not on the first reboot of Kitkat for me, which worked fine. But just randomly on reboots after the update to 4.4.2. The slowness starts at the initial boot screen because the animated splash screen with the green swirling around the Nvidia logo is super sluggish and slow-mo, almost like the tablet is running on one core or something. If this occurs, I normally hold in the power button to force a hard reboot, then its fine again. Done it maybe a handful of times, but I don't restart my tablet that often. Only started happening after the 4.4 update tho.

workaround

This is not a solution, but instead a workaround that seems to work.
a) Firstly you need to turn on the 'developers options' in the settings menu.
Go into 'Settings' > 'About tablet' then tap the 'Build number' seven times.
You will get a message telling you that you are now a developer.
Return to the main settings page and a new option 'Developers options' will be visible.
B)Click on 'Developers options' > 'Select runtime'. Then click 'Art'. This cause android to rebuild the runtime system & libraries. When its finished optimising apps, use the tablet as normal for 10-15 minutes, note some apps will NOT function properly.
Restart tablet by powering off and turning back on.
C)Goto main 'Settings' page click 'Developers options' > 'Select runtime'. Then click 'Dalvik'. Android will rebuild the runtime system & libraries and return the tablet to its original state. When its finished optimising the apps, Power off the tablet then restart.
I hope this helps… (does not require unlocking or rooting)

[Q] Some apps have started closing immediately on opening

Earlier today, a few apps on my Nexus 7 have just started closing within one or two seconds of opening them.
Google Search Bar, Facebook and Catch Note all close within a couple of seconds after opening them. I have used them fairly frequently for the last few weeks with no problems. Other apps, such as Twitter, Chrome and some games all work fine.
I have turned my device on and off a couple of times, but the problem still persists. Any ideas?
The problem is still occurring for me.
Gmail, Calendar etc... all also closing within a second or two of opening. Is this a common problem?
Is your N7 all stock or do you have a custom rom?...custom kernel?
You really need to provide some information in order to get help.
I haven't seen it in the OP so: Reinstall them

I haven't rooted my Nexus, or anything like that, it's all stock.
I just uninstalled Facebook, then downloaded it again. It seems to be working. Other apps still have the same problem. I assume that I have to do the same for all other apps - but is that even possible for apps such as Gmail, Calendar and the Search Bar?
Uninstalling and re-downloading hasn't worked as I had hoped.
It seems to have worked for Facebook. But I did the same for Catch Notes, and although it worked for a minute or so when setting it up, after creating a test note, it force-closed, I opened the app up again, and the old problem of closing within 2 seconds happened.
Other apps such as Gmail, I uninstalled, 'updated' again, and nothing changed, still closes immediately. There is no error message, it just returns to the home screen.
I thought that Task Killer might have been a problem, but I uninstalled that, restarted the Nexus, and the problem persists. Actually, when I turned off my Nexus, and tried to turn it back on, it was stuck on the 'coloured X' screen for a few minutes, I had to hold the power button down, and turn it on again. I'm starting to worry about my Nexus now.
Update:
A couple of other odd ones.
Google Drive doesn't even open. When clicking on the icon, the normal shading effect happens, but nothing else, no window even for a second.
Google Calendar opens, and just has a white screen, as if it is ready to load the calendar, but nothing loads. It doesn't close, just remains on the white screen, which can't be backed out of without pressing the home button.
Have you tried doing a cold-boot on the device? Maybe another app running in the background is causing conflicts. Where there any recent apps that you've downloaded?

I have just followed the instructions for a 'cold-boot' and now my Nexus can't get beyond the 'X' screen...
I have held the power button down a number of times, and tried turning it on again - but the 'X' continues to be displayed for over 20 minutes.
Just managed to turn my device on - but the problem still exists.
I didn't download any new apps that seem to have caused this problem. Though I think an app might have force closed and the Nexus displayed an error message such as "android/Google system stopped working" (probably different) and my home screen went blank for a while. Everything reappeared though after a short while. It could have stemmed from that.
Sorry about another bump, but i'm wondering if anybody has any more ideas before I go for a factory reset?
Edit: Actually, I think that I have found the cause of the problem. I just opened a game (Let's Golf 3) that I was playing before the problem started and after a few seconds, a message popped up saying "Unfortunately, Launcher has stopped". When I press OK, it returns after a few seconds.
I pressed the sleep button, and my Nexus turned off. Now trying to turn it on again, having some problems getting past the 'X' screen again. If I finally get in, should I uninstall the game? Any other solutions to this problem?
If your N7 can boot up, go the isolate & identify routines - disable/uninstall or freeze the golf game - do a normal shutdown/restart.
If normal functionality is back, you've just found the source. Not a gamer myself except for Angry Birds ... , but from the Play Store description, it access & make changes to system & protocol, etc. as you should contact/email golf's tech support for resolution. Otherwise, take a look of any background running apps or widgets, newly added or updated.

Thanks for the help.
I couldn't get my N7 to boot up, so I finally gave in and did a hard reset (by holding power + volume down, Recovery Mode, then wipe data etc...) but my N7 still won't boot up
I have wiped it twice, and rebooted it, yet it is constantly stuck on the 'X' screen. What on earth can I do?

I would flash the stock system image.

My N7 isn't rooted or unlocked.

You will need to download the factory image, unlock your bootloader, and flash it. There is a guide on this forum, it might be stickied.

I was hoping there was going to be a resolution to this other than a "flash to stock" suggestion... My Nexus started doing this exact same thing this past Sunday when it ran out of power completely and needed to be recharged. After it powered back up from charging the following apps quit working altogether or just started quitting once it appears they try to access data: Netflix, Currents, Zillow, Gmail, HBO Go, Press (though Google RSS Reader works), NVision, TegraZone and a couple others. I have done the reboot thing as well and almost had this thing brick again (stuck at X), but I managed to clear the data cache from the fastboot menu and it started up again. I'm now at the point where I'm troubleshooting individual apps but the clear data/cache, uninstall - reinstall process isn't working for any of the broken apps. This is now the 4th time I will be facing a 'flash to stock' situation as it appears that I've had every problem that leads to this 'fix'. I'll try a couple more things (mostly deleting and clearing everything) but I'm really frustrated with how many times I've had to flash this damn thing. sigh.

[Q] Lollipop 5.0 has turned my Nexus into a pretty paperweight - help!

So I finally got the notification that I could update my Nexus 4 to Lollipop; I was aware of some issues regarding performance/wifi etc but nothing prepared me for this;
I installed Lollipop last night and left my phone optimising its apps etc overnight. In the morning I had a couple of messages saying the launcher was not responding, I also noticed I had no wifi or mobile data connection.
I restarted and my wifi connected but the phone promptly froze and needed another reboot. After reboot it took a long time for even the 'no signal' triangle to come up and much longer for it to show any service, but still no data connection. Various apps are causing popups asking me to close, wait or report. Normally it won't respond to any of these options. I've not even tried to use most of the apps, such as Google Docs which has come up a few times.
Within a couple of hours all I had managed to do was let Gmail steal my emails and get a quick glance of the 'new look' (which I like).
A bit more careful handling got Spotify running for my drive to work but it froze and needed a reboot after removing the aux lead from the port.
Then it stopped responding and I left it for the day as I was working, when I came back it still said 9am on the screen. I cleared the cache via the recovery boot process, performance has improved but its still freezing and the data/mobile reception is very flaky. In 24hrs I still haven't managed to use the phone for anything except Spotify. Not even loaded a web page. Its probably had 20 restarts today.
Help!
Just done the following and there has been a marginal improvement i.e. I can actually open an app (occasionally) without freezing the phone but its still largely unresponsive and no mobile reception at all.
Go into the developer options as above. There are three options under "Drawing" in Developer Options :
-Window animation scale
-Transition animation scale
-Animator duration scale
Turn all three to 'Animation off'.
then, under the 'Apps' subheading (in developer options still), set Background Process Limit to "at most, 2 processes".
My N4 and N7 have been flying along since I did that.

Nexus 4 wont launch, optimizing apps

Hi.
Yesterday my Nexus 4 turn off and then turn on again, on screen after boot animation appeared a windows that says "Optimizing apps" so I wait till the end of the process but after that phone wont launch. I tried to launch him many times but each time was the same. So I just flash the ROM from here
https://developers.google.com/android/nexus/images
then launch a phone but he stacked on boot animation for 30 minutes and I turn it off, lock the bootloader and the "Optimizing apps" window appears and phone went to the state from beginning.
What can I do to repair it?

Try flashing the images again and try waiting longer, sometimes it takes a really long time to boot the first time.

Lag and random reboot

Have been using PA 6.0 for Nexus 7 flo for a few days. It has been a decent experience so far except these two problems-
1. There is a significant amount of lag at the multitasking screen when you are attempting to switch between apps the tab freezes for a few seconds. Sometimes I have to reboot to make it work again.
2. Have been getting random reboots quite a few times like one per day. While using it suddenly goes blank and shows up the 'Google' logo followed by the boot animation and it would start up again. (no bootloops though)
Everything else is working fine for now.
Edit: The lag only comes into play when Auto rotate is on in landscape mode or when switching between potrait and landscape mode.

apps freezing bug

Hello, I'm facing this bug since some time ago (don't remember if this started with the pie update or not).
When scrolling an app (Twitter, Reddit, etc) sometimes it gets stuck and there's nothing I can do for it to become responsible again, the only thing that brings it back is pressing menu button and multitask to another app or to the same app that got frost and everything goes back to normal. It's weird. I think I has something to do with the screen shut down time because those freezes occurs when I stop scrolling for some seconds and when I want to scroll again it gets stuck as explained, probably approaching the time limit that the screen is set to shut down for inactivity... Also, when u try to scroll and realize it's stuck, when you multitask and get back to the app that got frost, you see that it actually scrolled it was just the screen/image that was stuck.
If there's anyone facing this bug or knows a fix?
Cheers.
