I was using sensorly, and when I locked the screen it attempted to block it when it asked me a question. My phone vibrated for a few seconds as it fought to overcome the fingerprint screen (and failed)
The fingerprint scanner wont initialize (always ready... but never really). I have to reboot(haven't yet). I can't stop the process/service either... no idea why.
Anyone know of any fixes?

I own a Nokia N810... from my experience rebooting kills the life of your battery with these kinds of devices, and this happens like once every 2 days for me

When you say life of battery do you mean it discharges more energy than it would if you didnt reboot it? Or do you mean the battery itself will die months sooner than it would have.?
Battery capacity lowers over time. Booting that thing clocked it at 400Mhz (the top speed) for about 5 minutes, eating up a whopping 5-20% of the battery.
I noticed my battery lasted less and less every time it crashed and rebooted (it does it so much now that its pretty useless (read: every 10 or so minutes) - thanks nokia)
I have a feeling its the same way with Lithium Batteries too... The battery life is about 40 minutes (if im lucky) and I used to get like a day (of moderate use).

Its impossible to kill the fingerprint reader service. I find that kind of strange.
Sent from my MB860 using XDA App
That kind of makes sense. I think the fingerprint service might be an integral part of the system so you can't fully kill the process... Kinda like the android process.
And the comment about battery dying after a reboot faster is true. If you reboot a phone, especially these android beasts with 1ghz+ processors, revs up the processor to max, essentially eating up a large chunk of battery because it would be running at max for 5-10+ minutes. It's crazy. So unless you wanna do a lot of charging, don't restart too much.

Well on one hand I'm happy to see it's not just me. On the other hand it sucks that it consistently happens. For me if I continually run my finger on the scanner on a reboot it will unlock the screen. Then, after a bit (or a few locks) it will stop working and just say "Initializing Fingerprint Scanner" or something along those lines. I ended up disabling it and using a pattern as a screen lock.
For me it happened after installing a ROM that had 1.8.3 as its base. I've seen some previous mentions of the issue I'm seeing and tried their fixes but they haven't worked. I'm eager to see this get fixed. Otherwise I really like the device.
I use widgetlocker and once in a while it won't work when I first wake it up but if I hit the back key and go to the default lockscreen it initializes right away and I can use the scanner.
Holy run-on sentence, Batman! Sorry

I may have been able to reproduce it. Unlock your phone, then immediately lock it, then immeditely wake it. Killed the fingerprint sensor.

Yeah for me, and maybe this is a similar state/situation, I find it really happens when I swipe the unlock screen after waking the phone up rather than the fingerprint sensor.
It happens to me sometimes.
But instead of rebooting my device, I go to Settings -> Location & security -> Change screen lock. There I use my password/pin and then I wipe my fingerprints already registered and start all over again.
My system update is the one before 1.5.7 I guess (the android updates are called OTA ### right?)
Hope it helps someone who doesn´t reboot the device.
Thanks
Whenever my phone goes to sleep, and I try and turn on the screen again, it simply reboots. This occurs in airplane mode with nothing enabled as well
Unlocked, CM7. I flashed different roms and they all had this, I don't think it happened on stock.
Any fixes? All the threads I've seen have no real info
Seems like your system files might be corrupted. Wipe system partition from fastboot or cwm then reflash your rom. Any time I had weird stuff happen on a rom, I wipe the system then it goes away. Hope this helps you get rid of this issue. Good luck!

Doesn't work, just wiped system, cache and dalvik, then flashed rom and sod's still happen.
I have also tried flashing several radios, all with sod's. Any suggestions?
wakelock
I had this problem on stock and every rom I tried (this was actually the reason I unlocked) I installed wakelock app from the market. I set it on partial wakelock. I think it keeps phone from going into deep sleep. It worked for me. I think it may make battery life a bit worse but having to pull battery sucks. Since I also have the issue on stock I am prob sending it in on warranty

So you've had SODs since you got the phone? Wakelock seems to work, but kills the battery.
For anyone who does NOT have SODs what modem/radio are you using?
Yes had them since I got the phone. Wakelok fixed it for me. Battery life is not horrible. It still last me like 14 hrs moderate use. I have tried radios and everything else I could thing of. Think mine is hardware related. That is why I am sending it in. I was surprised to find out it was still under warranty
I've just noticed that when mine shuts down, it gives a green notification first, then when I try turning the screen it, it reboots.
Unfortunately, my phone is out of warranty, I bought it used
SODs still happen in airplane mode.
Try wakelock and post if that fixes it.
Call Motorola directly. I bought two used. Had the same problem. They replaced them both with new units.

Just don't say anything about buying it used.
Good luck.
As posted above, wake lock works but uses battery.
I live in Canada and am out of warranty, would I still be able to call?
It's worth a try. You have nothing to lose.

I had the same problems.. but mine happens when phone gets above 35°C.. So I activate wakelock at this time until i see temp is lower than that.. after that I disable wake lock.. it's a pain in the ass.. but it is better than pull the battery out once every 15 min..

Is there something specific about 35C, and are you sure it is exactly that?
I have installed 2.3.6 Bell and I still get reboots, anyone have a link to stock 2.2.1 Bell SBF that I can try?
sometime 35 sometime 36.. but above that temp.. sod kills me.. under that temp phone runs smooth..
I'm a system enginner but I haven't program in years.. I'm thinking seriously in create just a services to read temp and launch a wake lock when temp reache some level..
I'm pretty sure I will help lot of people but aint sure when i can start doing some work

my phone would not actually reboot but in went into SOD (sleep of death) so every time this has happened to me i installed a new kernel or reinstalled the one i had.........always rectified the issue.
Same issue
I had the same problem when I flashed CM9 and then when I downgraded back down to CM7, I tweaked the kernels I used and changed my UV settings and it hasn't happened since. Perhaps flash a different kernel and see if that works?

Tried several of them, this seems to happen on stock 2.3.6 as well.
I flashed a stock sbf to return to stock. Still had the sleep of death. Reboots after and during phone calls, and touch screen problems. I believe it is hardware related.
When I lock the screen of my Galaxy S3, then press either the power button or the home button to show the lockscreen, about half the time it takes about 2 seconds to show the screen after button press. I've searched and seen S-Voice caused this problem so I disabled that. I also removed my SD card and rebooted but the same issue still occurs.
Any way to fix this because my HTC One X didn't have this problem...
Thanks.

Power saving mode is already off. I don't particularly want to flash a ROM unless I have to because I've had warranty troubles in the past. Are you certain a ROM would fix it? Which ROM?
And I also tune lock screen off.
Do you install any power save app??

I get this also. Got it on the Stock ROM and ARHD. I have also seen this on my gf's Galaxy Ace, but only when upgraded to GB. On Froyo (Yes, that old version) it turns on instantly. So think it might be a Samsung thing. Not yet tried an AOSP ROM on my S III yet so may give that a go as itching to get some Jelly Bean on it.

Lag is hardware-related looks like. Present on CM10 based ROMs as well. On stock-based disabling S-Voice helps just a little bit when it comes to waking up from Home button...
Killing me as well. :\ What I getting used to is to press Home while pulling phone out - straight away so by the time I get it in position to work with, the screen is either already on or will be on in a 200-500 ms.
Still this is a most frustrating "feature" of SGS3 that will most likely force me to look for replacements once those are available on the market.
The issue is still present even in the latest Paranoid Android ROM.
After tweaking a bit, I found that if you have WiFi enabled, will cause this lag.
Just disable the WiFi and you get instant screen wake up.

This problem annoys me to death too. I've tried many ICS/JB stock ROM and custom ROM (including CM10), but none of them could solve the problem.
I did notice some trend: right after a reboot, the screen turns on fairly quickly. Then after turning on the network (mobile data or wifi) and use facebook or other apps that access network for a few minutes, the delay starts to increase to the usual ~2sec. Looks like some network process might be causing the problem. FYI, My cousin's Note 2 don't seem to have this problem.
Any hacker out there can give some hints or help find out what process might be the culprit?
it's because the phone goes into deep sleep, to prevent this you can download a app that named softlocker. you may get not as good batterytime.

From what I see, I don't believe deep sleep is the problem. My LG P500 (running ICS) goes into deep sleep all the time (per CPU spy et al), and it never has this problem. Seems to me like something else is causing this...

no other brands have this problem. only samsung, thats so strange.
I too suffer from wakeup delay of 1-2 seconds and it's driving me crazy.
After 2 long years I had to live with majestically f**ed up LG Optimus 2X, I finally decided to throw that junk away and get a phone that works as expected, phone performance of which would be equal to it's price (and the price was not something that limited me).
Now I own a phone which even though is snappy and nice and everything, takes ages to wake up. And what pisses me off the most is that Samsung is OK with that, because obviously majority of the customers / owners is OK with that. How is that possible ffs. Low end devices for fraction of that price resume from deep sleep almost immediatelly (in time I don't consider waiting). How's that this is not a big issue ?!
Sorry, I'm just frustrated
EDIT: To add something constructive ... the deep sleep really is the problem here. If the phone doesn't go to deep sleep, wake up to lockscreen is instantaneous (try that by yourselves with SoftLocker app). It's believed that S3 suffers from this issue because of the way the GSM modem is integrated with (or in ? I am not sure) Exynos4 - source.
I just smacked my phone in the table, while in my pocket and now I"m experiencing the same problem. Is this even possible, or I had it before and just didnt notice till now?!
Is anyone else getting Android OS around 50-60% battery use?
I have tried every ROM included going back to stock. I have ran the phone with nothing but Stock and no apps installed for a day and still get the same drain so I can only assume its a kernel issue.
I am not familiar with LG products in the slightest, but I had a yellow screen of death the other day...something I have never seen in my years with samsung android products. Anyone have any idea what this is maybe it is pointing to a hardware issue?
LG made a great phone, but I don't think I will keep it much longer. Locked boot loaders, no sources, and history of terrible updates have me regretting purchasing this phone. I tried my hand at building a working jb release when I first got the phone and it is going to take a skill set I do not have and I hate waiting on a company to do what they've never done in the past..

Easy, brother. I have only had one of my apps/utilities run higher than AndroidOS ever on this phone; however, that said, I think there is a problem with the way it's being calculated. I'm getting really good battery life with good sleep and still AndroidOS shows the highest by far. I know that's abnormal for it to be so high and still get good battery life, but it is what it is.
Edit: you've installed the fast dormancy toggle, right? As for the yellow screen, I've seen it once in my two months with the phone, just rebooted and carried on. Forgot what they said it was...but it is here in this forum somewhere.

I was just about to post something similar. Andriod OS being high kind of makes sense if nothing else is using the battery, although you would expect that number to fall significantly with increased screen on time and heavy app usage, which it doesn't ever seem to.
I've been having horrible battery drain lately. I'm currently traveling for business, and just use my OG for web surfing and stuff when I'm in my hotel. I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from Better Battery Stats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals. I'm underclocked to 1350 and using powersave gov with deadline.

Believe you are correct. There were issues on the Samsung Infuse and even the international SGS3 for a while... it was referred to as 'memory leak.' Has been worked out by devs on XDA. You can put memory leak in the XDA search above... it's above my pay grade.
Edit: It's great to see another RD here... hope you will reconsider keeping the phone and stay !!

Thanks for pointing me in the right direction. I have Google+ uninstalled, but part of me thinks Google Now may be partially the culprit (although why that would be the case with all radios off, I don't know).
I'll try a fresh install of the 2.2 kernel and see if that helps. Thanks.

I would be less inclined to believe it is a faulty measure if we had a different ROM not built off stock (AOKP/CM10) that could produce different values. However, I seriously doubt anything built into either of the two custom ROM's is geared toward normalizing that reading. That's why they are both the same as the stock AndroidOS percentages. Jivy is probably right that it's a kernel issue. With the size battery we have, imagine the potential if it is a true reading (androidOS out-of-control) and we can get it under control down the road. We're talking double the current best battery life you've ever had on this phone at the very least.

Get BetterBatteryStats, select Since unplugged and Alarms to see what is waking the device (making it not go into a deep sleep). eBay was a big culprit for me.
The wakelock that keeps the phone awake during background data transfer (screen off) lasts 6 seconds (I am guessing it does it in multiples of 6s) regardless of how long the sync takes. Everytime email, facebook, gmail, drive, picasa, twitter, g+, google maps, ebay, calendar, contacts.. whatever wakes the phone to check something, it will be a minimum of 6 seconds.. This adds up over the course of the day and it is counted in the Android OS. Shut down syncs you don't absolutely want/need and this number will go down. All phones with the Snapdragon S4 Pro has it, especially the Nexus4. It seems they've done some kernel work to fix/reduce it but I havent really looked into it since I don't have that phone. I've seen complaints in the Droid DNA forum as well.

Check out this thread: http://forum.xda-developers.com/showthread.php?t=1987032
If anyone is experiencing this problem, I hope the following steps may help.
I would like to express my appreciation to XDA members, who have commended and helped out with this. Credits go to @LordManhattan and @abuihsan . Many thanks for your help.
1/ Do a re-flash: I always thought my device was a c6802, after I flashed c6833, it helped.
2/ Do a factory reset/ Cache wipe/ Dalvik Wipe/ in recovery or in the phone settings.
3/ Install SD-Maid and clean the mess from the programs, also take a look at APPCONTROL to see which is running. You can freeze it here.
4/ Install Performance control to Underclock your CPU. Believe me, 1.7Ghz is far too enough for all the tasks you need.
5/ Use more pwerful tool, like Titanium Backup to stop all the backgound-running apps. You just need to leave the one which were in GREEN color.
6/ Use Wakelock Detector to see which apps get your phone out of deepsleep. Mostly they are Facebook and Messenger. My advice: Disable Facebook notice and if you don't use chat quite often, don't install facebook messenger.
Hope these help.
Personally I had tried a lot of methods, including checking the processes and re-insert the memory card but no such helps.

Hi everyone,
Recently I just bought a ZU from a local vendor here. It runs 4.2.2 with no problem. However, I want to get rid of the *new system update* and I also want to use the xperia Themes, I decided to upgrade to 4.3.
My phone model is C6802, and I chose the file here : http://forum.xda-developers.com/showthread.php?t=2453921
The upgrade went through fast and smooth, as I had experienced in many Sony devices.
However, after getting to 4.3, I had noticed some problems as follow:
+ Heat: Device heats up very fast, even left alone. Just imagine you have the phone on 100% battery lying on your table, a moment later it heats up and the battery drops dramatically.
+ Battery drop: Just as mentioned above, the battery drops quickly. I do not expect extreme battery life on this device, but since 4.3, it is too low, I can barely make it to 6 hours without doing anything consuming battery.
+ Process: When checking the battery, I notice that most of the process that takes up battery is Android OS, which nearly 50-60%. I use the phone frequently to answer SMS and call, sometimes play games. I think that the most used applications should be the bad-ass screen?
I am running on the 14.2.A.0.290 with R4B.
Anyone had experienced this problem before, or know a solution to fix? Will clearing the Dalvik Cache help? I had re-flash several times but the problem is still there.
Many thanks in advance.

Sounds like somethings has gone wrong in the update process.
Have you tried backing up all your data and doing a factory reset?
I do not think clearing Dalvik will help you here, sounds like something else is acting up. You could try to install one of the apps designed to detect what is causing the wakelock.
I'm not at my Android tablet at the moment, but I think I used this when I had this problems myself on my Galaxy Note: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector

First of all, thanks for your reply and suggestion.
I had tried to flash the roms multiple times, but the problem still exists. Furthermore, I even flash back to 4.2.2 and the problem is still there. The phone heats up slowly and battery runs out pretty fast.
I had installed the Wakelock Detector on my device and I will update the situation tomorrow, I will leave it there for a night and see the status tomorrow.
Did you wipe after updating? I had the same issue when i updated to 4.3.
Correct me if I'm wrong, but as long as he's been downgraded to 4.2.2 again, he'd have to wipe. At least that is how it was on my Xperia Z.

this might not be related, but I've been noticing much worse battery life today than normal! i normally only drop about 50% in 24 hours, but today I've dropped 30% in just a few hours. Android OS seems to be doing it...
no real heat issue tho, maybe slightly warmer from whatever the OS is doing, but nothing too major. running stock rooted 4.3
had that on my Xperia Z on a 4.1 or 4.2 build (dunno which one). Sounds strange, but simply turning off the sync fixed the problem, give it a try :laugh:.
Hope it also helps on your XZU.

At first I did not choose to wipe Data in Flashtool, then I flashed again, this time I checked everything.
the problem still exists.
UPDATE:
Yesterday after working hours, I had rooted and installed BetterBatteryStats, Performance Control to monitor the system. I also had WaveLockDetector and Titanium Backup installed.
It appeared that the CPU runs all the time, in the highest state (2.15 Ghz), the phone never goes to DeepSleep and Awake all the time.
On Performance control, I had underclocked the CPU to 1.5Ghz and the temperature seems to be cooler.
I had tried to freeze a lot of applications via Titanium backup but so such luck.
Still researching.
However, many thanks to your kind replies. At least I know that I'm not alone with this problem :good:

I ever had no deep sleep problem with 4.3, even in stamina and airplane mode, and with location-off too, I checked with BBS and found the 'trigger' is a process under google now app. I use GREENIFY and get the google now hybernated. Everything fines now and I still can use google now as it only hybernated when not in use : )

hey, thanks for your reply. I did the same to you, even with Titanium backup to ensure this will never shows up again, but CPU keeps throtlling at 100%. I still can not find an answer to this 100% thing. now the phone is quite hot in my pocket, I decided to put in my bag and even turn off to keep it from heating.
I will try another rom and update.

do you use any cleaner/task killer app? before trying other rom or update, maybe you need to uninstall it, reboot recovery and wipe cache and see the result.
I don't know if this is relevance but while using greenify I also uninstall the previous cleaner app and replace with another one that I think is better.
now my c6833 has great deep sleep.

Hi, Thanks again for your advice.
Would you please give me the name of the cleaner apps that you think are way better?
Are you running on 4.3 stock or on some modified roms?

The thing is, you don't need a task killer/cleaner app. It was useful way back on Android 2.1/2.3, but you shouldn't use it at all on 4.0+. You're actually making things worse.
mine has been heating up as well. the battery isn't draining like how yours is, but any kind of use will heat the top back side of the phone. I checked and after killing all apps, my cpu load was still around 65%. is that normal? no custom flash here. locked bootloader. updated through pcc normally. I'd imagine this is why 4.3 isn't running as buttery smooth like everyone else.

No, that's not normal. Mine's around 20-30 degress celsius (depending on what i'm doing). Even streaming 1080p videos shouldn't make it hot or even mildly hot. When i had the heating problem, two cores would always be stuck at 2150 MHz. Now one core is active at 960 MHz when the screen is on. CPU load is around 20 and 60% (single core). Temperature is currently at 26 degrees. Also, stop killing apps and processes. Most of them are set to start automatically, so when you kill them over and over again, they'll start again and they'll use even more battery. Android is built to manage resources very well on its own, and it's not operating like Windows or any other computer OS. Just leave it alone unless something has gone rouge and you don't have a choice.
I'm on stock 290, rooted and extremely debloated.
- Current battery level: 88%
- Current uptime: 3 h 30 min
- Current screentime: 1 hour (browsing etc.)

hmm... yea that sounds like the problem i am having. im noticing two cores stuck at 2150mhz with a third kicking in here and there. how were you able to fix it? just a fresh install of .290?
so as far as the apps go, i have Du Battery Saver installed and the "optimize" button is supposed to clear up some of the background junk. are you saying that i should leave the optimize button alone and just let android figure itself out?

What i'm saying is that you should uninstall that crappy app. Task killers were useful three years ago when Android devices had slow processors and low amount of RAM. What you're doing now is killing everything everytime you tap that button. WHY do you want to do that? What's the point of having 2GB of RAM when you don't want to use it? Are you always killing processes on your computer too? Would you do it if your computer had 32GB of RAM with 30GB available? Unused RAM is wasted RAM. Android is a modern OS that can handle this on its own. If you only have 300MB RAM left and you want to play Asphalt 8 which requires (i'm guessing) 500MB RAM, Android will find the oldest and less frequently used process and kill it. It's that easy.
You can read more about it here and here.

I think it'll be a little easier if you tell us what you've done till now. We have no idea what you've tried and not tried.

ok. so I haven't done anything at all to remedy the situation. I figured I'd ask about it before messing it up myself. I upgraded to .290 via pcc. it updated fine with no errors. once it was done updating, it was hot and battery was diminished. I had seen on another thread that most people had that happened so I didn't see it as an issue, just a side effect of the update process.
I have been checking back to see if anyone was having heating issues with 4.3 after the update and didn't hear about it until I had seen this thread. the OP stated he flashed .290 on his 6802 and is rooted. I am not, so I wasn't sure if the steps he was taking were the same given my 6833 being completely stock.
