[Q] Huge (2-120 minutes) lags with play store install uninstall, sms, root - Android Q&A, Help & Troubleshooting

Brand new Note 4 SM-N910C. Rooted in a first day and worked excellent for several weeks.
I recently start experiencing strange lags in lots of different places in android. Eventually I start thinking that they are related.
1. First of all SMS coming 5...50 minutes late, sometimes 2 hours late... If I put SIM in another phone, they arrives instantly. I cannot login to systems with sms passwords (online banking), because they are already expired when arrive.
2. If I click Uninstall in play store, it in 100% cases stuck in uninstalling... it is labeled as uninstalling and remains in this state for the 5...30 minutes. Then when I click Install again (does not matter what kind or what size of application or what connection I have) It usually stuck in the middle of downloading even if it is 150KB app. After 5...30 minutes it jumps to 'Installing' step and stuck here for another 5...30 minutes...
3. Most apps that want root access usually don't get it instantly, it also took some significant time... I usually even don't catch a moment when SuperSu finally asks me about permission and obligated to grant it manually in SuperSu...
4. There are a lot of other different minor lags that I usually never experienced...
This is obvious some software issue and I'm pretty sure that hard reset / restoring factory image can help, but this is too easy and didn't reveal the real cause of problem... I want to know how to deal with it in the future.
And finally, I just noticed in logcat this lines:
SecureStorage SPID (0x0000006B) wrong ready flag
SecureStorage SPID (0x00000000) could not connect to secure storage daemon
SecureStorage SPID (0x00000000) internal error
It is really hard to say what I did to achieve that, may be there is some update rolled... But first symptoms appeared 2 week ago and I really don't remember what I did.

[Q] Official ICS update causing reboots

I know I know, I am very late to the party.
But anyway, I finally installed the ICS update a few hours ago.... and my phone won't stop rebooting now.
Its not a boot loop, because it does get into Sense UI and I can use it, but eventually after a few minutes, it will reboot all on it's own with no warning. I assume its loading my (rather large) list of apps from the SD card since I have never seen it reboot until it finally wakes up, realizes a SD card is indeed mounted, and starts populating my app list. I never saw that process finish from the few times I bothered to watch it.
I tried removing the SD card and now its no longer rebooting, so unless taking out the battery did something, I assume its likely the SD card.
Is there any way to tell what is causing it without reformatting my phone? I REALLY don't want to wipe out everything.
After some testing, I have found two issues with the update:
1. It seems that it is not any one specific app, but the NUMBER of apps on my SD-card causing the reboot. I have somewhere around 200-250 apps installed on it. So far I can put about 80 or so of them in .androud_secure and it will work fine, I do not know exactly what the braking point it, but I know that having around 140 apps causes it to reboot every 5 minutes, regardless of which apps are on there.
2. I can't load my text messages anymore. Any contact who I have had a long history of texting with, it just gets stuck saying "loading". I can still receieve messages, but since I can't actually open the message list anymore, I can't reply!
I would really like to avoid doing a factory reset if possible, is there anything I can do about this?
I was consideing just doing a SMS-backup and then flashing a custom rom, but I like the 3D feature and it seems like there is not a SINGLE custom rom out there that supports 3D, and many don't support 4G either.
Please, does anyone have any advice?

i9300 lock up problems - seemingly at random

Hey guys,
I'm hoping somebody here might have an idea for where I can start to look for this problem, I have had the SGS3 for around a year now, I put CM10 on it initially (from memory), upgraded to CM10.1 when that was released via the nightly releases and I have been running those since.
Recently I updated from a Feb / early March release (cant recall specifically which one) to the next latest (mid to late March I believe) to move from 4.2.1 to 4.2.2. I believe a little after that ( if not that day) I began to very occasionally have small lock up problems with the phone. It would lag out for a short amount of time, or would just completely lock up on the screen its on for a while (if I leave it, it can be between 30 minutes to an hour before it becomes responsive again)
Often I would need to use it so I just end up having to hold the power button in to force a reboot to clear it.
Initially I thought "ok just a bug in a nightly, that's cool, it'll be patched out soon enough", a few days later a nightly came down that fixed a notification bar drop down loop problem I was getting but this other thing has stuck around, depending on how my phone feels its occurring a lot or a little each day, generally seconds / a minute after I start to use it.
I have since jumped around on a few more CM10.1 roms and I have even reverted to the 4.2.1 roms I was using ( I still have them on the phone so I know they are the right ones) to test if its that, but now they are encountering this problem as well.
The phone is completely clear now of user data, I have done a full data clear via CWM and even the original Google "welcome" setup section has locked up more than once in my attempts to set the initial configuration of the phone....
Any thoughts? CWM etc has never had a problem so while it seems to lean toward hardware i'm still thinking its software, maybe a CM10.1 release has updated something else in the phone that's now causing problems, something more firmware related etc?
EDIT: to give some examples, just before I readded my exchange details and started to sync contacts etc, I went into contacts, opened the menu and selected "Settings" to change the first name last name sorting and it just stopped on the settings button, settings was still lit up etc but it was not responsive.
Just now (about 30 minutes later) I have pressed to turn the screen on and its on the lockscreen. Great its back I think, i'll grab the baseband / kernel etc to put in here, I slide it to the unlock and bam, frozen on that now.
more info
I had a play this morning and activated the CPU overlay etc as well as strict mode.
The phone has just done it again in the play store, however the CPU overlay shows nothing out of the ordinary and there was no screen flash to indicate a long run causing a problem.
Interestingly the cursor in the search bar for google play is still blinking, so the phone is still "alive" however i cant control it via the touchscreen or the hardware buttons.
I am trying to dump the log via ADB now however its gotten as far as finding the phone and seems to have stopped (though maybe its still going, i'll see soon hopefully)
Anybody got any ideas? This is driving me crazy and i'm not sure where to go with it now, i guess back to stock is the next option then maybe a warranty claim if thats still possible....
Log collected
Either it was still collecting or it collected after the last event in the log but i've uploaded the log to pastebin here:
http://pastebin.com/Cc20CYZH
The main thing seems to be this:
Code:
W/SQLiteConnectionPool( 6385): Requests in progress:
W/SQLiteConnectionPool( 6385): execute started 646409ms ago - running, sql="COMMIT;"
W/SQLiteConnectionPool( 6385): The connection pool for database '/data/data/com.android.email/databases/EmailProvider.db' has been unable to grant a connection to thread 237 (AsyncTask #2) with flags 0x1 for 646.44104 seconds.

And also this:
Code:
W/InputEventReceiver( 3327): Attempted to finish an input event but the input event receiver has already been disposed.
FYI - that bit at the bottom of the paste about the screen turning off with timeout, the screen has now turned off but i still cant turn it back on etc, soon enough it'll probably reboot (which seems to be what it ends up doing) then it'll be ok again until a problem occurs again.
I'm currently trying a new baseband as recommended here:
http://forum.xda-developers.com/showthread.php?t=2133401
Will post the results after a few days, fingers crossed.
Did you had the same problem on any other aosp or aokp based roms?
Or just try flashing the stock rom

I actually never ended up changing back, i flashed the new baseband as above, ran the dumm file generator app a few times (letting it lock up as it went), flashed a new rom a few times as well and after all of that it seems to have worked out all the bad sectors.
Definitely seemed like I was a victim of the beginning of the SDS problem, all due to the fact i had flashed this almost immediately after receiving it and had never updated the baseband.
For those with lock up problems, go to http://forum.xda-developers.com/showthread.php?t=2133401 and follow that for installing the baseband, then do the dummy file generator etc, i'm back to a phone that works properly
PS - It took a few weeks after for it to find and remove all the problems, remember your actual ROM install could be written to bad sectors so i would definitely recommend after you run the dummy file generator a few times to update your ROM at least once, it was after 2-3 updates mine had completely settled down.
PPS - If the dummy file gen fills up your storage then crashes, just go to app info (drag from launcher is the easiest way to get here) and clear the data, that'll delete all the dummy data
PPPS - The dummy file gen can make your phone run terribly as it gets close to full, be patient, its not necessarily the lock up problem but even if it is you need to let it sort it out itself, restarting will make it worse not better.

[Q] Android gets into a hotboot looping state for unknown reason

Hi.
My Galaxy S3 is frequently getting into hotboot looping state for no apparent reason. The only way to get it out of this state is to wipe the phone or restore a backup of the "data" folder only.
After that, it might work for a week, but it might not work for a day (not work = start to hotboot loop).
It happens when after the phone screen is locked, it doesn't wake up anymore. It doesn't answers to any calls (like if it's off) or notifications. Just dies.
Forcing a reboot (by holding the power button) or removing the battery ables me to reboot it, but enter in hotboot looping state. I can make it go thru the whole booting state and I see the homescreen (And that's weird because I'm supposed to see the lockscreen first). Some widgets animation works but the device doesn't answer to touch (two softbuttons vibrates when touched, they do vibrate but don't render anything on Android) and then hotboots. Keeps doing this forever. Booting into safemode USED to work, but it doesn't work anymore, I don't know why.
After wiping the device or restoring the Data backup, device turns on as expected (restoring data takes it back to working state exactly like it was before the backup, even the same lockscreen pattern). I've tried to leave a terminal running logcat to catch the error, but it doesn't write in realtime, so when the bug breaks out, the logfile is empty.
I even thought it could be the S3 memory issue with firmware, but I'm using the "fixed" kernels. Also, it is recoverable, and not permanently dead.
I suspect of some rogue app, but I have too many apps to just go through installing one by one (and waiting even weeks to install the other one). Is there any way I can get a postmortem logfile or make logcat write in realtime?
Thanks

Try flashing another ROM for S3 and doing a full wipe.

I already did. It started to happen out of nowhere while I used the Android Revolution HD ROM, then after a few wipes and reinstalls with the same problem, I gave a shot to WanamLite ROM. Exactly same problem. Both are based on the original 4.1.2 Android.
I'm pretty sure it is being caused by some rogue app, because the only thing in common between those ROMs is that I "batch-install" all my apps back from Google Play.
So far, I'm suspecting about Vine (it's the last install that I remember since it started to have this issue) and I have already uninstalled it, but it might have been caused by some app update that broke hell to my phone.
If there were some kind of "black box" that I could retrieve after a crash, it could be the solution

If you wipe data, your apps disappear, so I think this is not the problem.
Do another full wipe and DON'T restore your data. Just download again from Google Play and see if the problem appear again.

I started doing this the first time, but it still crashes it. And as I was wasting too much time with this, the backup option came as a option to not have to click to download over 200 apps one by one. Also, it once happened during a long holiday, and I was in a friend's ranch with no decent internet connection for downloading. All my apps were gone and I was stuck with a default phone for five days.
The backup is exactly the point where I finish downloading all the apps and they're installed. There are no cracked programs or adapted (e.g. Nexus camera). Every single app is obtainable from Play Store, so it's pretty fresh
Funny (actually sad) thing is that it's a system-wide error that a wipe solves it. If I don't wipe data and reinstall the same ROM (which under normal condition is no big deal), it doesn't get past from boot screen.
The worst is it happens instantly. It's working now, but then it crashes. Bam, gone. Few hours ago I was texting my gf and I left the phone for a while, waiting for her answer. After some time I knew something was off, picked up the phone and it was pretty warm (first signal), with the LED blinking some Facebook notification. Tried to wake up but it is in coma. I force a restart and it hotboot loops like I described on first post
It -only- happens when screen is locked. I disabled the screen lock for now to see if it's a workaround, but I'm not holding my breath
It could be a hardware malfunction if it can carry through all the roms you flashed and even when you tried a fresh install without your apps it still happened.

That's pretty much discarded. Wiping data instantly solves it. It did indeed run for 5 days with no external app without a single problem.
But also it ran over one week with external apps without a problem. I've executed some memory integrity tests and they all reported a-OK.
I'm kinda ruling out the "rogue-app" issue. I thought that recovering "data" from NAND backup was the /sdcard/android/data. But it's deeper than that. Now I don't even have a lead.
Phone already crashed today, without Vine and lockscreen, so that's not the problem. I really need to get some logs out of him. Just need to know how. Only if it could write a realtime log, so I could pull through ADB.
My last resort will be a fresh-fresh android installation, default S3 i9300 ROM, with only essential apps. Already have it triggered for the next crash.
If it goes rogue even this way, I'm running triangleaway and returning it (will be a profit too, the silver border is stripping).
This time around, I'm trying running it without a external sdcard (several files were being corrupted in it, don't know if it's due to force restart by removing battery, or some real issue on the card)
It's a problem within the Facebook social app or Youtube.
I've managed to run the phone flawlessly for weeks without signing in on Facebook, suspecting it might be it.
Today I logged in on Youtube app accidentally, and had to login on Facebook app to retrieve some info. Three hours later, phone went mad again.
I don't know which app caused it, but I think there's some relation to Facebook due to a greater ~involvement~ (couldn't find a proper word.. forgot it) with Android.
I've changed ROMs, launchers, system versions.. but not Kernel. I'll try another kernel and report on Boeffla main thread to see if there's some known bug

[Q] Reboots every evening after getting 4.2.2 update

OK, this is really weird - after getting the 4.2.2 update, my phone reboots itself every night, not 100% sure it's exactly the same time, but it's been while sitting in my pocket or on the table, not even in use. At first I assumed it was Zooper, which I had installed right after the update, but I disabled it yesterday and got the reboot again tonight.
I even checked my Tasker to make sure some auto-reboot profile hadn't installed itself!
Any hints about how to diagnose this? Do I have no choice but to remove apps one by one? Most of the apps I run are the same ones I run on my TF300 tablet which also has 4.2.2, so don't know if it could be an app.
Did it again tonight and it is the exact same time - 9:19pm It's also interesting is that this is about the time of day I did the update to 4.2.2 It's like some daily thing going on. It must be some new app applied by default by the update, I've disabled some of the obvious new apps.
Does anyone know if I do a factory reset will it go back to 4.1 (which worked fine for me), or will it stay at 4.1?

the Factory reset will erase all ur Apps and will stay in 4.2.2 ......
Looks like this update has really screwed up my phone. After a couple of more nights of trying to disable more apps, and trying to catch the error with logcat (nothing that makes any sense in the log, no error or crashes preceding the reboot) I decided to factory reset.
It rebooted again tonight, about 24 hours after the factory reset.
Also, intermittently now the power button will not suspend the phone, though I can hold it and reboot, I don't know any other way to put it to sleep.
Looking at the log some more, the only thing that gives any hint is that there was Location Services activity before the crash. Googling around about my problem showed there was a bug in Location Services early in 4.2 but the claim was that it was fixed. I guess tomorrow night I'll try turning off Location Services as well.

The update may have screwed up somewhere in the middle, you could try to re-ruu your phone or unlock the bootloader and flash a custom rom, also the thing about the power button not putting the phone to sleep or doing anything than reboot on long press happened to me on each and every custom rom and I never did any OTA, got my phone, unlocked bootloader and flash away from sense, my hboot is still the one that it came with, but for me that thing happens really randomly, like once every 1 or 2 weeks, and when that happens for me the volume buttons stop working also till reboot, I was thinking I was the only one facing it so I kinda decided not to talk about that as I saw no one say anything about it, but I am also one of those for who the phone turns off exactly when my phone goes to 6% battery whatever I do, on whatever rom I am and even in the recovery, so I was thinking that maybe vodafone modified something on it, that's an other reason I didn't say anything about the buttons becoming unresponsive...
So what I would recommend is to re-ruu your phone or go to a custom rom (or if none solves anything the phone may have some kind of hard brick).
Just to help out anyone else who ever has this problem.
It was not location services.
I can see clearly in two logs an HTC process crashing. This seems to cause a cascade that leads to reboot.
I contacted HTC tech support, they suggested I boot up in a recovery mode and try to wipe data cache. They were surprised to find that attempting to do that caused a reboot.
So as Ranomez suggests above, they want me to re-do the update with the RUU when they release it, which they said would be "soon" last weekend.
On the other hand, my battery life after this update is fantastic, so I've decided I can live with this to not have to worry about recharging by mid-afternoon!

Device Secuirty: Unauthorised actions

Hi there fellow S6 edge owners.
my version of Samsung S6 Edge is Hong Kong's G9250, only got this phone two days, ago, I used to have an HTC One m7 and always rooted with custom roms, but seems like Samsung has done a great job this time, I am going to stick with stock rom for now.
Strange things happened to me after I purchase from the store and with the helpful staff from the samsung store helping me setting up this beauty. Not long later after I walk out of the store the Following message from Security Log pops up: "Unauthorised actions have been detected. Restart your device to undo any unauthorised changes"
So I restart my phone, thinking it's no biggie, but the message would reoccur any time in between 30 to 2 hours, or when I am updating and installing apps as a new phone. I didn't transfer any old contents, nor having install any apk manually. The rom is stock as it can be.
So I factory reset it, and the same message would keep popping up, I scan my phone using the security app and no threats were found, but I had to restart my phone to make the notifications goes away, I start to suspect there might be something wrong with the rom itself or the kernel, so I decide to Factory reset it in under 6 hours of purchase, after booting on and signing in, the message would come up again!!
So I took it to the store, and asked them have they seen this? One of the manager said you need to cleared the app preferences and clear the credentials. I also updated the security policy myself. but still no luck. So they gave me a new one, with in 20 minutes of setting up, the message "Unauthorised actions have been detected. Restart your device to undo any unauthorised changes" Comes up again.
I am just wondering if any other is experiencing any similar issues? This is getting annoying.
same issue
Im having the same issue with Australian stock.
I too am having the same issue on Australian stock. :/
I'm having the exact same issue with Hong Kong stock. Tried everything from reinstalling to clearing the app preferences.
Has anyone found a solution to this annoyance? I don't like these notifications popping up every 5 minutes!!
If youre rooted, Use TitaniumBackup and freeze "SecurityLogAgent"
it'll get rid of those popups

same problem here as well
So, I was faced with the same problem as you all above. I did a bit of research and speculate (I'm still not 100% on this) that this security bug is linked with the keyboard Samsung has preinstalled on the device. Try disabling it, using another keyboard, or just disconnecting it from any network it may use (mainly to update your dictionary regularly.)
What I did exactly:
-Reboot phone into recovery, wipe cache partition, factory reset.
-Start up phone, security threat came after a few minutes, before anything was installed.
-Restarted phone through security to reset kernel
-On startup, disabled keyboard and enabled swiftkey. Scanned, result: secure.
-Enabled keyboard, but disabled all features. No problems. Scanned, result: secure.
-Enabled features one by one, no problems yet. No problems. Scanned, result: secure.
-Reset keyboard settings. Scanned, result: secure. After a few minutes, security was triggered.
As I said, this may or may not be related, but this is the first time I've been seeing my phone as secured since I bought it.
I read somewhere that the problem is known.. and should be fixed in an update...if you are rooted you know what you have to do
Had the very same problem which disappeared with the update to 5.1.1. Have a couple of colleagues who suffered as well as the update cleared it up. Unfortunately from what I've read 5.1.1 kills the prospect of rooting without triggering Knox... Should have done more research before rushing to update...
