Vibrating then crash?

Has anyone else experienced this on DK28? It's happening to me quite often.
Is it an unavoidable bug?

are you running stock?

Mhmm, no custom Rom as of yet. Is it a stock only issue?

What are you doing when the phone does that?
Sent from my Evo Killer!!!

Running Facebook, or running the Android market or tweetcaster or the XDA app, but it's stopped so far oddly enough.
EDIT: It still persists to happen. I still haven't figured out why. It's always when the keyboard is out typing. Swype, the Samsung Keypad, as well the GB keyboard.

I get that. Running ext 4 viper rom.
Vibrates twice then reboots.
Then when it turns on, I've went from 66 percent to 13 percent battery life for example.

Same as well. Either the app crashes or my phone will reboot. I reinstalled the leak again and it persists to be that way still. Hopefully the official comes out soon, but for now I'm fine with this.

Does it reboot or shut down?
It sort of sounds like a low battery shutdown. Maybe there is a problem with your battery. I'm just guessing here.

I have seen that happen from a couple of scenarios...
Not doing a wipe after going to DK28
Switching between roms and not wiping
Or flashing a rom or theme that you failed to verify the integrity of the zip before flashing.

I had this problem for a while and it seemed to get worse over time. I backed-up everything and wiped the cache and factory reset in CWM. Seems to have fixed the problem so far.

I'm going to take your approach to it and try that, hopefully it goes well for me, if not I'll just deal with it lol. Either way I have a functional phone. That vibrates and closes everything lol.

I will report that last night this happened on my walk home.
Phone kept rebooting over and over.
Phone was in my pocket and my hands were full so I could do nothing. Absolutely nothin would bring my device to life expect reinstall the rom. Even when I pushed my data backup I made while it boot looped on me, it would do the same.
So I had to start fresh. I have to say, previously I may have had a bad installation.
I went from 100 to 1 as to calibrate the battery once, no reboot yay. Also before, playing music while getting a text only muted the sound of incoming text for a plit second to where yu wouldn't know if not paying attention, sounds like a skip.
Now it decends volume while sounding the alert, and return music volume as normal.

[Q] Data corruption upon clearing cache/Dalvik?

First off, i always do a nandroid backup before flashing a theme or ROM.. which usually saves me.
I've noticed recently that, pretty much every time I clear the cache 3 times, then clear Dalvik 3 times, (in clockwork 3), after flashing anything, upon reboot, i get the boot animation, then vibrate, then double vibrate > bootloop.
This seems to happen even if I don't flash anything following the cache clear. Has anyone else had this experience? I'm more interested in the cause of this. I've since restored everything manually, but I'm a total flash/pushaholic, and looking for ways to avoid this situation. Any help is appreciated.

Did you properly shut your phone down prior to the cache wipe? As in power off then wait for the vibrate to signal it shut off.

Why are you clearing cache and dalvik 3 times after flashing? Once should be plenty sufficient..
As for the cause, I would assume its the dalvik clearing.. cache is its own partition, where the dalvik is is on the system partition, and you are probably corrupting it with excessive writes..

Also remember that the version of CWM 3 we run on the Epic currently is not official. It can be a PITA sometimes. Dameon has done an awesome job porting it so we can have ext4, but I'm hoping some of these issues get cleaned up when we have the official version.

Hm, I almost never do that, but I will start. I usually do the death grip, then reverse death grip into recovery. (Can i trademark that name?)
@Mattalica: also good to know I'm not totally alone on this. I hadn't considered that. Thk God for nandroid + unyaffs
@Chris41g: i was trying the cache wipes on their own just to try to isolate the issue.
Thx everyone for feedback.

If your phone is running a "no-journaling" Rom that will cause corruption.

No journaling alone will not corrupt data. You have to shut down improperly or have a lockup caused by an unstable App (like beta wireless tether) or an unstable overclock/undervolt.

Yep, I know you know what your talkin about. I just didn't want decalex to take your response out of context, as some have been stating that the lack of journaling by itself causes corruption.

Is the vibrate, then double vibrate during the boot animation (then loop) indicative of "data corruption" ?
Next time it happens, I'll try to logcat.. I'm curious what is actually happening .. unless one of you already knows.

Bluetooth issues

Anyone have issues turning on bluetooth while running the new 4.0.3/4.0.4?
It takes me a good dozen trys for it to turn on.

nope, no problem at all
maybe you just need a good clean & wipe, to re-install everything from scratch again, instead of restoring backups

I have tried doing that, along with multiple different roms. Always do a darkside wipe, than factory wipe before rom in stall, than darkside cache wipe and factory cache and davik wipe after.

have you tried using just a plain stock rom via ODIN?
just trying to rule out if it's a hardware problem or software problem
if it's a hardware problem, it shouldn't even work at all, so it still seems like just some piece of software preventing you from properly enabling/disabling bluetooth

I too will have intermittent Bluetooth issues with a couple of 4.0.x ROMs and I did not use any app restores. Usually a phone reboot gets it working again though.

OK - installed Clones/Drones v4 ICS yesterday, and Bluetooth will not turn on today - just stays at attempting to turn on bluetooth.... And yes I followed in install procedures to a tee. Will try a different ROM today.

Yes, I still have the same issue after 2 repair attempts by samsung. First attempt, they flashed the firmware, second attempt, they replaced a component. (Never told me which component)
When I try turning on bluetoot, it just seems like it's trying to enable itself, but just hangs. I have to restart the phone several times before it works again.
I have an SGH-T989 factory unlocked and using it with Straight Talk

I'm using stock 4.0.4 and I've only had my phone crash once, and that was when I turned on blue tooth and quickly closed the status bar and tried to open an app. It just rebooted and was fine after that.
The blue tooth on this phone turns on almost instantly compared to my old Galaxy Ace though. Either way, I think there are a few blue tooth issues with this phone, just not ones that I notice as severely as the OP

FYI: I have a stock Galaxy 2 and after the recent update, I'm getting bluetooth issues when connecting to my car, bluetooth stops.

Lit Screen Woes. My phone's bright beautiful and won't shut up.

I would love it if my screen stayed off when I'm not using my phone. My screen is constantly lighting up. Many different things can trigger it, but once the screen is lit up, it stays lit for hours. This is very stressful. I have not modified my phone; it is stock. I have installed an Snes emulator and Worms Armageddon. That's it.
When I'm charging the phone, I'm usually asleep. When the phone completes recharging, the screen lights up and stays lit ALL FREAKING NIGHT. When I wake in the morning, I have to reach over and hit the button. When it's in my pocket and I receive a text, the screen lights up and STAYS LIT until I reach in and hit the button. Sometimes the phone is lit for an hour or more before I notice the heat in my pocket.
Also, this phone is huge and beautiful and I love it, but it's so wide in my pocket that the power button is constantly being pressed somehow. This also causes the screen to light up and stay lit inside my pocket. So far on average 80-90% of my battery is CONSTANTLY CONSUMED by this screen constantly turning on and staying on when I don't want it to. Do I have any options?
Is there a rom that addresses these issues?

1. Happened a couple times on my wife's stock rooted phone. A dalvik cache clear set it right whenever it happened.
2. Get a TPU case that has holes for buttons. This way buttons would be accessibly only by accessing it wantedly, and not by pockets.
3. Install greenify, and push all games to that. This way your emulator would be put to hibernate mode until needed again.

Yep I'm crazy. I flashed back to stock and low and behold it wasn't there.

I don't feel much closer to a solution here. I would really like to know: Is this behaviour normal for the S3? Do your phones do this too? Or is it just mine? My Galaxy (original) never did this kind of thing. It would light up, then time out, and turn off the screen, like a phone should.
Just today, I open my work locker to check my S3. Screen's on again of course. Why is it on? Because I got a text 2 HOURS AGO. I just .... don't freaking understand this behaviour. It's AWFULY FRUSTRATING AND STRESSFUL.

1. I looked it up. A "dalvik chache clear" requires that I install something called the "Clockwork Mod" - is that right?
2. I have never used a case for my phone and I NEVER will. I suppose I'll just have to put up with the button problem. I'll be more careful maybe.
3. How would pushing my games to greenify solve my problem? Doesn't android automatically hibernate all unused apps anyway? And do you think my Snes emulator is affecting my phone in the way I described? I don't think it would.

1. Yes
3. If an app requests to access resources like internet at regular intervals, android doesn't stop it. Greenify stops this from happening by disabling the app completely. Consider it on lines of disabled service.

I +1 on greenify!
Its a great app!
But don't hibernate apps such as Facebook,Gmail,Twitter, anything with push notifications. Since greenify "freezes" them until you open them manually, you won't receive any notifications. But nonetheless its a great app and battery saver

Greenify sounds great and I'll likely get it.
But none of this addresses the issue: My issue is not with the phone's efficiency. I know it would be fantastically efficient if it didn't permanently light up the screen every time I received a text. This wears out the screen too! THIS is the problem and it's a real big problem!
EDIT: "To prevent spam to the forums, new users must wait five minutes between posts" - Okay but why do I also have to wait 5 minutes to fix my typos? GRRRR!! Website design oversight, I think!

Yeah I checked that. it's always been set to 30 seconds. Thanks though.

To me it sounds like you dont have anything on your phone so why not do a factory reset? You can use SMS Backup to keep all your texts, and everything else is synced. If you dont want to factory reset, then I don't know what.
Id just root it and put a custom recovery such as TWRP and clear both caches.

[FIX] Lollipop Lag, slowness, signal issues, bad battery life, etc.

If any of you are having Lag, slowness, signal issues, bad battery life, etc. and/or other weird glitches after the lollipop update you need to factory reset your phone.
This is a know bug with updating from Kitkat to lollipop. It has happened on many devices, Nexus 5, nexus 7, Shield tablet, N910A etc.
Just factory reset your phone and re-set it up and most if not all of the problems will be gone.
From my brief understanding it has to do with some downloaded apps not switching from davlink to ART correctly during the OTA process. Facebook on my shield tablet was a notorious culprit.
Just an FYI hope it helps a few people out.

We did have one person factory reset to attempt to solve the "heart rate light turning on" bug, and it did not solve the problem.
Have you noticed this bug or used S Health yet?

One list I always go through is: update, update all apps, boot into recovery, wipe cache, and reboot twice. Works great and I know a bunch of others see similar results

Luckily I was already running ART prior to the update to 5.0.1, so I haven't seen any of these issues yet, and hope none crop up. :good:

Luckily I haven't had any of the glitches a few people have mentioned. However, my friend with an S5 needed to factory reset hers after being pushed the lollipop update and it smoothed everything out. Just like when flashing a ROM guys...starting fresh helps a lot.

Anytime there is a major change to an OS, whether it be on my PC/Mac or my phone, I always factory reset and start over. ALWAYS. Too many little bugs and quirks pop up in software upgrades for me to waste my time with that stuff. I'd always rather start fresh...plus then I can weed out the apps I don't use anymore.

As an old habit, I always do a system reset after a major upgrade. I did the same with this upgrade and it has been running pretty smooth for me.

I am now experiencing lag in a bunch of places, yet I did a factory reset.

I did this right here cause I noticed my battery was draining a good amount when the phone wasn't being used. After this and a full charge, the phone went back to how it was before.

I wiped cache and factory reset 3 times and I haven't experienced any of the aforementioned issues.

This is what I did. I had absolutely no issues with the update.
The minor issue is the quick note app pops up very slowly. But that is fairly minor, and not significantly different from kitkat.

factory reset
I rebooted a couple of times after the update, and wiped cache in recovery. Still experienced lag all over the place, especially w/ the dialer. I factory reset last night and it's been running more smoothly since.
Has anyone noticed that when booting into recovery, it says "installing system updates"? I even got a message, before the recovery screen popped up, that "no command found". After that popped up briefly, the phone went into recovery and all seemed fine.

Yup,
Dead Andy then into recovery. Weird...

This update to lollipop on the note 4 has been the best update experience that I've had on any phone. Love it. And yes, factory reset solved many issues that were honestly minor and I really didn't feel I had to, but I did bc I'm crazy. ..but it was worth it.
Back up phone via kies, I am impressed it worked great.

I'm going to try this again. I've already done it before but hopefully this will fix my problem.
On 4.4 I went 2 days with heavy usage. It was insane! I use my phone a ton at work for RDP, videos, and other IT related stuff. Now I can barely go 1 good full day.... Really hope this fixes it.

My update went well without any troubles, but now I am few weeks into using Lollipop and I definitely notice faster battery drain. I also have disappearing icons, just like others complained (Google Hangout and Phone icon disappeared).

I'm not experience a lot of major issues....but I did do a recovery reset....but I reinstalled via kies. I'm planning on doing a recovery flash again....but this time I'm not going to have it install the apps.

I'm not experiencing this I'm actually getting very good battery life. Don't know if you have disabled the system apps you don't use???
Also something I always used to do when I had the T-Mobile note 4 rooted of course, I always disabled Samsung push services it was always recommended. Don't know if it would make any difference but you can give it a shot.

I have all the apps I don't use disabled and it still hasn't been helping. I'm thinking about calling ATT and getting an exchange
