Phone optimizes after every reboot. - Nexus 4 Q&A, Help & Troubleshooting

Why is my phone optimizing after every time I restart my phone. I'm getting tired of this. Why is it doing this? This is a stock rom. It comes up as a black screen with a white dialogue box that's says Android is starting...optimizing apps. Can someone help me stop this? This has been going on for about 3 days.

Did you do anything to your phone when it started, or did it happen out of the blue?

It happened out of the blue.

I suggest that as soon as it is up and running you straight away do a full back up with a product like "wondershare trans mobile" This will give you a full backup of all your data, apps,contacts and SMS etc.
When you have done that it's time to do a full factory reset using the Volume Down Button while pressing the Power Button this will show you the bootloader use the Volume UP & Down to select factory reset. then press the power button to select start.
When it reboots you can connect to your USB to your pc and copy back your contacts sms etc.
I hope that helps
Keep us posted as to how you do>

Dialer lag

Does anyone got noticeable delay in start of the call when tap contact from the call history list?
I suspect it started after latest (1.31.405.4) ROM installation and happens periodically - you just tap the contact and nothing happens (sometimes at all but sometimes it reacts after minute or so and suddenly starts to call).
There could be at least two causes:
1. No reaction on actual "tap" (hard to explain why it finally calls sometimes but I noticed that Call button could give different reactions comparing to clicks on actual contact)
2. Process that executes call is doing something in the background (freeing up memory? restarting? doing some sync?)
After it "breaks through" it works for some time seamlessly - you just touch the contact and it calls immediately but after some time (even after phone reboot) the glitch is back
NB. I uninstalled almost all apps (including beautiful Timeriffic) I've got from Android Market and prey it's not related to the Exchange Sync and apps around it... Let's see if I still have problem tomorrow.
same problem i got. any solution pls tell.

Same problem
it could be a memory leak or something who knows,
the phone hasnt been out for long and there may be more updates comming.
plus if its a performance problem then when android 2.2 comes out with the JIT compiler it should be faster
lifeis, do you have any applications (in addition to pre-installed) on your device?
Version 1
The more I observe situations when dialer "hangs" the more I suspect that it happens due to some synchronization. Already several times I noticed such behavior starts when "data" icon indicates some outgoing traffic but nothing comes back (no active incoming arrow). Could it be that it tries to sync contact (with Exchange? Twitter? Facebook? Gmail?) and at the OS level it sees that network is "available" (somebody here already complained about similar issues) so needs to time-out instead of skip that attempt and proceed with requested operation immediately?
mee too
Today i notice that when i press the contact and after i pres power button screen goes and comes and phone starts dialing. I think sync cause this. May be latest update they can solve this. I had a hero and hero did n't have problem like that.
Dialer lag present on my device aswell. its not often and oddly happens when no apps are running in background. I think it conflicts with whatever sync services may be syncing at the time one tries to make a call

Same with mine. There is also a lag when I press the "Sync All' immediately after a WiFi connection is established.
Hope they fix this as it is quite annoying. And also make Maps 4 "officially" available to Legend.
Same problem
I started after updating the legend software!
Anyone have a solution?
Is it possible to go back to earlier software?

Does anyone willing to try? Not sure that I'm ready to spend another half a day restoring all settings and configurations after factory reset (also suspect that chances to succeed are not too high)...
Ah c'mon! that's like "hey do you have a problem with one application in windows? Ok that's the solution: go to ms dos and then type "format c:\"....
Ridiculus. HTC should just understand what's going on and release an update!
The reset actually works. I have not re-installed all of the applications i had before and did not use the backup file to restore the phone in its previous state so the dissappearence of the lag might be due to some setting being restored to default, but whatever the reason, the legend is now much faster.
Factory reset
Have you also installed latest ROM after factory reset?

Actually the update was still there after the reset - I didn't have to update again.
More observations
Interesting observations:
You try to call - dialer hangs
If you return to home screen you see that widget time is correct while status string on the top shows "outdated" time
If you try to browse some web page it connects and you see the content - I got feeling that this is some kind of "break thorough" since after that -->
Time at the status string gets updated
Almost immediately after that phone starts calling
Reset
Gave up and did factory reset - took couple of hours to restore it to the wanted state. Let's see if that solves the problem or I get issue back after returning configuration to the desired state.
Last observation I did before reset: problem disappears (or minimizes?) if I keep WiFi off - especially if Legend sees some network around but isn't connected. The same applies if it unsuccessfully tries to connect to some faulty router - most probably dialer lag starts after that...
Hi everybody,
Factory reset helped here. I didn't make lots of tests but after 3 days of using I didn't notice the lag.

Michal

Hi everyone,
I had the same problem and the factory reset helped me,too.
I believe that either the rom update or one of the applications I have installed was causing the problem.
Now I will begin re-installing all the applications I had before and see if the problem will reappear again.

It appears that storing (remembering) wifi networks slows down connecting to any of them when present. When I only have one network remembered connecting to it is almost instant, while as soon as I remember other network setting, connecting to same network is much slower, even if is the only one present.

[Q] Nexus S 1st day and its froze, cant unlock

Hi guys, having a problem with the nexus s that i have just got today.
Installed an app for getting wallpapers, something like FLickir HD wallpapers or something.
Set a wall paper, then browsed on through others.
Phone soft rebooted, and now the screen and bottom buttons are totally unresponsive. No idea why, and no matter how many times i battery pull etc i cant get it sorted.
Any help would be a great help.
Can you get into recovery mode?
Pull battery. Wait 30 seconds. Put battery back in.
Press and hold volume up button, then press hold power on button.
Phone should enter Fastboot mode.
Use volume keys to highlight the recovery option.
Use power button to select it.
Once the phone starts to reboot you'll quickly see a little box pouring an arrow into an android figure, hold the power button, then press hold the volume up key. Timing (on my phone) is important, you need to be holding the power key first, then get the volume up key while the box and arrow are still there.
If you get to the Android and triangle, you might still be able to do the two buttons to get into recovery, but it doesn't work on my phone; some reports on various blogs say it does, though.
Once in Recovery, you should be able to pick the option to factory wipe/reset the phone. This will wipe the ROM space and reset the phone, but it won't touch the sdcard stuff. You'll have to set up the phone again, but that's not too difficult.
Just trying it now. Didnt realise about the 2nd stage of the power button and volume up. Just rebooting now after the reset.
Seems to have worked with the phone setup.
Will all my apps be gone?

Yes, all apps from the Market will be gone.
So will your wifi settings, user accounts, EVERYTHING, except the sdcard contents.
You're basically putting the non-sdcard part of the phone back into the same state it was in when you took the phone new out of the box.
I'd recommend appbrain.com for your phone to have an easy way to reinstall apps if something like this has to be done in the future.

Ah, so much the better! It should just sync up after logging in with his account.
I thought I had to acknowledge I want that feature when I first set up the phone.
Either way, Appbrain still a neat combo of website discovery and phone installation, I find it very useful.
Ive been using app brain and the apps are being re installd.
However some of them that are in my list on the webpage, are not showing up in the app on my device. Any ideas why?

No, not sure, but if they're on your webpage, just click onto their links for the full app description page, then and cancel install if it's there as an option, and then install again.
this happend to me with two phones
Last night after my phone froze after downloading a wallpaper, after an initial pull of the battery the phone booted but the screen was unresponsive to touch, after I tried a hard reboot, with no success, I took it to best buy today and got a replacement. (Phone 1)
I Did system updated asked by the OS after i turned the phone on. (Downloaded update via wifi, and no sym card was in the phone) After Boot it was unresponsive to touch just like the last one. (Phone 2)
I went to Best Buy again and got a 3rd Nexus S. Have not done the system update and the phone is working well....for now
Any thoughts??????

Sprint LG G2 - Lock screen not activating, Home soft key not working...

This just started occuring this afternoon before and after I installed the latest ZVA firmware:
1. The "Home" soft button responds to my touch - as in I get the visual and haptic feedback as if I've touched the soft button but it refuses to actually DO anything. I can hit the Home button on any screen and any app and it takes me nowhere.
2. The Lock screen is no longer activating - as in I let the screen hit the timeout and let it set for a few minutes. If I try to "knock" on or use the power button, it opens right back up where I left it with no Lock screen.
I hope this makes sense. I'm really stumped here. Like I said, it just started happening this afternoon and I figured that it was some weirdness to due w/ the pending OTA update. After installing the OTA update, the problems persist.
I'd rather not do a factory reset, but I will if I must

Bringing this old post up as I just now encountered this on my AT&T LG G2. It occurred when I was using Google Maps which then crashed and caused everything to freeze. Upon reboot, I get the exact same issues as stated above. What was the outcome for you guys? Did you end up doing a hard reset?
Everything appears to be functioning with the exception of above. I'm suspecting a software issue with the home launcher as the soft keys are responsive but the Home one. The Notification Bar lags when trying to drag it down, but none of the notifications are functioning. I also noticed a significant amount of lag. Prior to the "crash" my phone was flawless with no lag for the past 10 months. I absolutely have no clue what just happened...

No sound on lollipop?

Fixed problem by wiping cache from stock recovery
Anyone else flash factory image and now has no sound what soever? Completely clean factory image flash and no headphone or speaker sound. Only vibrations. Made sure everything was up all the way and tested on YouTube and play music and notification sounds. I saw one other person post they had the issue. So is it anyone who flashed factory image or everyone?

I have sound, but the button works backwards.
I was just coming in to ask the same question - no sound at all on my N10 on 5.0 factory image. Strange. Makes it really useful as an alarm clock, eh?
Fixed it. If you have the issue reboot into stock recovery and wipe cache. Works after that.
No sound on Nexus10 after upgrading to lollipop
I have the same problem as others with no sound from nexus 10 since installing lollipop.
I don't understand how you can do, what has been posted. Please can someone tell/explain how to do it.

I've tried following these instructions several times so far. Each time I get to the point where I'm pressing the power button to enter recovery, the screen goes blank for about a minute, and a "No command" message is displayed, along with a picture of a dead android robot on its back. The only thing I can do at that point is to hold down the power button until it reboots normally. I never see any option to wipe cache. Suggestions?

Mine did exactly same. Sounds worked after boot though..
My N10 with Android 5.0.1 will always cut off audio if I power it on with a headset plugged in. I just unplug the headset then reboot and wait until the desktop is displayed before using the headset. That's never failed yet.

When You see screen with android on his back (and triangle/exclamation mark), just one more step: hold Power button and tap Volume Up once before releasing the Power. A list of items should now appear at the screen. Now, you can wipe the cache partition (~10 minutes to complete).

I need help. I wiped out the cache partition following the above instruction but unfortunately, still no sound. The only way I have sound is via my bluetooth speakers. Any idea what I can do next?
I ran into this problem a couple days ago when booting after a recharge, with 5.0.1. No sound coming out of my Nexus 10, no matter what I did. Simply rebooting the tablet fixed it.
Just restart phone
All I had to do was turn my phone off and on. Running Nexus 4 on Lollipop.
Cause of the Sound Issue...
This is what we know based on several trial and error tests. The issue occurs when you have the tablet plugged into a charger and unplug it. Not sure why the issue is caused this way but each time it happens that was the case.
Solution...
After charging your Nexus 10 you will have to reboot the device once to get the sound back. You could go in and clear cache although its generally easier for most people to just restart the device. Have noticed best results when the tablet is on then turned off and back on again as opposed to just turning it on from a dead state.
I know this is annoying and more of a temporary solution but it will get your sound back just the same until Google pushes out an update to fix the underlying issue. It is annoying having to reboot the device each time you put it on the charger but for the time being it works.
Hope this helps.

For me it also kills the front mic but the back one works. The solution of restarting fixes sound and mic for me.
So its not just me. Good.

Reboot With NO Attached Devices
Try rebooting your Nexus 10 with all connections to external devices detached and off. This means NO power supply, NO bluetooth, NO HDMI cable, NO headphones, etc.
You may need to do this a few times. This worked for me when no other remedy worked, and I tried everything.

Trusty Note 4 Booting Issue!!

Hey guys, I have had my Note 4 for about 3 years now and it has never done me wrong. However, things have taken a turn for the worse... I started noticing a few days ago that it was slowing down on me, I mean, really slowing down. Big lag times when it comes to swiping to open the screen, or changing between apps, and the occasional self-shut down when the battery got down to about 15-20%. I had been putting off doing a self-update for a while, and when I finally had time to do one tonight, in hopes of cleaning it up, it is now lying on its death bed
I do not think the update ever finished (my phone is not rooted) but I was desperate enough to even do a factory reset and that has not fixed the issue.
Here are the symptoms:
As I go to boot the phone, I get past the Samsung Note logo and it looks like it is about to load properly, but then I get a popup that says "Unfortunately, the process com.android.phone has stopped" I hit ok and it keeps popping up again. I can't bypass it.. Then after I get passed that for a split second, another popup comes up that says "unfortunately system UI has stopped" It prevents me from getting to the home screen, in fact the screen behind it is black.
I have tried the following:
Clearing the cache partition from the recovery screen
I have done numerous hard restarts
I have gone through with a factory restart
That is where I have left off, and lost most hope, was with the factory restart. Now when I turn it on, I get past the logos and I can see in the background the page you would get as if it was a brand new phone (it says "Welcome! Preparing you device for first time use.." etc. But I can't do anything about it because I am still getting the same two popups that prevent me from doing absolutely everything!!!)
I have read about this happening and people seem to be able to fix this by accessing certain app setting and either resetting them, or clearing their cache. However, that is not an option for me because I can't get that far. I think something must have went wrong during the update...
Please help with any advice you can think of. I have been putting off rooting this phone pretty much because I was afraid of royally f****** it up, but at this point I am willing to try anything.
Thanks,
Eric
Hey guys, does anyone have any suggestions for my issue?? I am about to go out and buy a new phone, I have no idea what I can do to fix this. I have rooted it using Odin, but the popups are still occurring. I can't get the popups to stop, and they are preventing me from doing absolutely everything.
Is there anyway I can get it to go back to complete scratch? Again, I have done a factory reset, cleared the cache, rooted using Odin. I have done everything I can think of/what I have read I can do. I am willing to try anything at this point.
UPDATE: At this point my phone is on, and the only error message/popup I am getting is "Unfortunately, System UI has stopped." Behind that popup is a blank, black screen. The only option I have is to click ok, and the screen remains black.
Temporary solution that might work- Try logging in safe mode: Switch off the phone. Power it on and as soon as Samsung logo appears, release the power button and press and hold the volume down button. Release button when you see Safe Mode on the lower left corner of the screen. Try uninstalling all user apps in safe mode. To get back to the normal mode you can drag down from notification and disable safe mode.
You could also download the latest software for your model from samfirm and flash it via odin after factory reset. Could be a permanent solution.
why you just flash last frimware from sammobile,it will solve all your problems
SOLVED!!!
Alright guys, I was able to solve my problem, all thanks to this thread:
https://forum.xda-developers.com/note-4-sprint/general/stock-tar-odin-flashable-t3250864
I had already tried flashing a fresh stock rom, but to no prevail. I saw this thread and thought, hey why not give it a shot, and bingo! After downloading the .tar file for marshmellow and launching it through odin, she was good as new! So if anyone seems to have a problem with the system ui or the process phone.android popup, I suggest that thread.
