[Q] My Galaxy Nexus keeps re-booting - Samsung Galaxy Nexus

I was running Paul's custom ROM for the past week or so. I plugged my phone in to a portable charger because the battery was low. This is not the first time I have used this charger on this phone. After a few minutes the phone rebooted. I found this odd so I tried to figure out what was going on. I unlocked the device and went into settings....phone rebooted again. I tried reflashing the MoDaCo ROM, reflashing the original ROM and resetting the device. It still does it. Im still new to Android platform (moving away from a shameful iPhone) so Im lost on what the problem could be. Any ideas?

did you undervolt and tick set on boot without testing voltages?

No. I didn't change any of that. My phone is unusable

I think one of my apps is causing it. Is that possible even though I'm not running the app?

I have no idea. I think youre leaving out something.

After i restore to factory everything works fine. It starts again (doesn't matter which ROM I'm using) when Google syncs the apps I've downloaded to the phone. It's stable right now until I figure out what the hell is going on.

I would say app but you said you wiped everything..

Right. It works fine until Google starts to sync my data from my account. Is there a way to pinpoint which app is causing the damage?

Nevermind. It does it anyway. Hardware issue? Overheating issue?

Android is upgrading?

Hey,
Everytime I turn on my Nexus it reads Android is upgrading' - is this the normal procedure?
Sent from my Galaxy Nexus using xda premium
yes it seems to be normal with Android 4.0
Yes I have this too. Seems strange.

Yes, it'll do that every time you restart the phone

Yes. This is normal. This is where Android's optimization occurs (now with handy "Optimizing <x> of <y>" count to let you know what's happening) instead of prolonging the boot video. If it doesn't need to do that it just skips straight to launching the launcher, I guess...
Noted from observation, not from source code
My Galaxy Nexus only started doing this after both selecting "Encrypt Phone" and replacing my recovery image with Clockwork Mod Recovery 5.5.
It should not be happening on every boot unless you are a chronic flasher.
Mine phone did that on 4.0.1. On 4.0.2 that is gone

I got the "Android is Upgrading" when I zip-aligned all of the apks on my phone for the first time in GummyNex. So far it's only done it once, maybe twice in the last few weeks.
i only notice this after a dalvik/cache wipe. Atleast thats the only time it does this running 4.0.3 on my sgs fascinate.
Mine does this on every reboot, but I'm still on 4.0.1 where, based on earlier posts, that sounds more normal...
Only displays for a couple of seconds and nothing bad seems to happen as a result!
Mine started doing this after installing Google Wallet with that first crazy workaround. I hated it and restored my nandroid backup then used the apk that came out later and haven't seen that screen since. It definitely isn't normal to have it happen every time, except maybe in 4.0.1 I guess...
I just got this on 4.0.3 after wiping cache. Does anyone know what is actually doing. Rebuilding the cache?

Bump. My VzW GNex is doing this every boot. This has got to be fixable. Has anyone actually determined what is happening here? VzW Galaxy Nexus w/stock Android 4.0.2, rooted.

Fix what? Nothing is broken. The phone is making new app caches. That's it. There is no problem and there is no fix because nothing is broken.
its normal with my htc hd2 and nexushd2 v1.1 by tytung? =/

Me three, I saw it on every bootup until I got 4.0.2, now I never see it.
However, my phone's uptime is currently at 7days 38 mins and not lagging or otherwise needing a reboot/battery pull as older versions of Android seemed to need every two or three days. Yay ICS!
"Android is upgrading" appears when the system is generating ODEX files (optimized DEX). This essentially uncompresses "classes.dex" from the APKs, verifies them, optimizes them for the host (byte order, class prunning, ...) and writes them out in the dalvik-cache directory.
Dexopt should be performed when installing applications by the package installer though and it does it upon boot only when there's no corresponding ODEX file already. It also does it upon system upgrade, because the dalvik version likely changed and ODEX files need to be redone for the new VM.
This is a poor choice of words. "Android is optimizing applications" would be less confusing.

Crashing issues possible cause

I just had another crash replying to a post here using tapatalk. The keyboard had small pink corruptions as if video memory had an issue.
I pulled the battery for about 10 seconds, tried to turn it back on. No dice. I tried again except pulled the sim as well, that worked.
Maybe some of us having crashes are sim related?

I've had to do a second battery pull today. Phone locks up then about 5 seconds later the display goes dark. Not fun.

I froze twice in the past three days. I was using hand cent and browsing. The battery had to be pulled in order for restart.

Yesterday I noticed GetJar was keeping the device awake (in battery stats), but otherwise it was responsive and all good. I uninstalled GetJar and rebooted for good measure. It powered down fine, but wouldn't power back up. I had to pull the battery.
My first 'battery pull' so far!
I had my first crash today while I was replying to an SMS message. The screen produced these broken specs of green.
I couldn't exit from the SMS, eventually the screen turned itself off and then nothing.
I had to perform a battery pull to fix.
When the phone booted back up ICS complained that the launcher had crashed.
Instead of clicking 'stop' I clicked 'wait'.
Phone returned to normal after that.

Did you guys restore old apps/app data from your previous Android device? If so, factory reset and START FRESH.
I can't count the people I know that had issues all stubbornly because they refused to start fresh from a new device.

I didn't use a restore. I just added my Google account and let the phone download my apps that I more or less had from my Nexus One.
Is that OK to do?
Or should I have done something else??
Let me know, Thanks.

This is how it works. When you login all the apps install automatically.
I just noticed this morning that a bunch of apps I had uninstalled already on my GN automatically reinstalled. Odd right?

If you have "force 2d rendering" checked in the developer settings, that will cause many issues.

I don't have any dev options on. I'm basically seeing what others are. Lockup, sometimes with screen corruption, then the display eventually goes black some short amount of time afterward. Battery pull required. I thought it may be heat related at one time but it has happened when the device was relatively cool. Seems like a software driver issue that can hopefully be addressed.

On Boot Android is Upgrading??? wtf??

I
My GN every time I boot says, Android is Upgrading, start applications, what do this means???
Im still on 4.0.1 ics..
Any advice please
Sent from my Galaxy Nexus using xda premium
This is normal. Your phone is not updating its building app cache or something.
Search is your friend.
Question is though... Why is it always rebuilding?
Is it still completely stock from Day 1 of purchase?
Have you rooted it? If so, what method?
Have you installed any apps?
Have you tried doing a factory reset? (Ensure you back up your data)
The phone is purelly stock
I havent done nothing except using it and installing apps...the regular as an every day phone...i got since sunday
Should I factory reset?
Thanks
Sent from my Galaxy Nexus using xda premium
And what do that means?
Does your GN does the same thing?

Sent from my Galaxy Nexus using xda premium
If a factory reset will I lose my photos and the musics and apk's i have on Download folder?
Any way to back up that?
Thanks

mine does it to. its normal
I can tell you its not normal for it to happen on every single boot! It's probably an app that is causing issues with the os. Try and remember what you recently installed and uninstall a couple apps to try and narrow it down. This happened to me when I installed Wallet.
mine has done it since i powered it on out of the box the very 1st time. so i'd say its normal
I wonder why its doing it then? If on my device it only does it when system files are being played with but on others on every boot?
Happens for me too, only noticed it since upgrading to 4.01 (stock)

[Q] No data after flash, or reboot

I am having a reoccurring problem. Sometimes, when I flash a new nightly, or even just reboot my phone, I get no data. Even when I turn on wifi, it connects but stays gray instead of turning blue or teal. Same thing for my 3G. I have full bars, but it stays gray. Best way I have been dealing with it if wiping cache and reloading the rom.
I have tried going in and out of airplane mode, rebooting the phone, letting it sit for hours. I would just like to know if I'm doing something wrong.
By the way I am running CM10.
All in all, it's a small price to pay to run such a slick rom. And now that I got dual boot all figured out......much easier to try things out.
-Nick
Did you do a clean flash?
Did u use the sprint cm10?
Does this happen on tw ROMs?
Sent from my Samsung Galaxy Emperor using psycommu
I wiped everything except for data.
On sprint cm10
Does not do it on a tw ROM I have
So this is what you did
Was on random tw ROM>wiped cache and dalvic> flashed cm10
If so your only hope really is to wipe everything and reflasb

I finally figured it out. The problem seemed to be with my clock settings. I can replicate the problem by setting my clock ahead and reboot. Then I will not connect. I figured out it was a Google account sign in issue. If I then reset my clock to the correct time and reboot, no problems.
Just had a question about dual boot. Was it easy to setup? How hard is it to go back to single boot? I would imagine having two roms would take up a ton of space.

Am I the only one with Wifi sleep issues?

Just about every time my phone deep sleeps, wifi shuts off completely. I've tried multiple roms and kernels, and every advanced wife setting combination possible. Thinking it's a hardware issue in which case bye bye nexus.
I've googled and googled and only really found suggestions like "uncheck wifi optimization" or "make sure turn wifi off while sleeping is (un)checked". Tried all of that, and still persists.
Anyone else have this issue, or can someone give me an out of the box tip?
Thanks

You've probably already tried this, but have you tried a full wipe? Also, have you tried wiping you device's internal memory (SD card), and have you tried reverting to complete stock and starting over?
its a known issue with 4.2.2 roms, nothing much you can do about it, temporarily it can work but problem will repeat itself
I have done a full wipe, but not wiped the sd card, or reverted to stock. Hoping to avoid such a tedious task.
So my options are either suck it up, revert to a 4.1 rom, or get a new phone?

Thanks for your suggestion, let me try and report back later to see if this works.
This problem has been constantly bugging me that I want to dump this phone. Seriously disappointed with Google over all these bugs...
but I keep wifi optimization off... should I keep it on?
If you are unlocked, you can flash some custom kernels to fix the problem. I use Fancy Kernel and the developer included a fix in the kernel.

Work-around for Wifi drops (Kernel specific)
After fiddling with the Wifi Optimisation, I would like to report back that it DOESN'T WORK.
