Tab 2 shutdown issue! - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hello
I have a galaxy tab 2 gt p3100. My problem is that sometimes it shuts down itself which is very annoying. Any suggestions?
Sent from my SM-G906S using Tapatalk

Are you on stock firmware? using any particular rom? which android version? please provide details about when it shuts down. any particular app or activity? or is it random reboots? using gapps? facebook? or games? give us some hint.
Usually it happens when you overburden the CPU and RAM with things that the device can't handle, like Games with high requirements.

I am on stock firmware. Not rooted. When i take it out from the charging for some moments it stays awake then it vibrates and shutsdown.

i think it would b battry problem
Replace old battry with new one.
It could cost you nearly 2000rs

Greetings,
If it turns Off:
- Try a new Battery
- Check Battery Connector and Related Chip Temperature.
This black square chip should not overheat while the device is not charging. If its unbearable to put your finger in it over 3 or 4 seconds... Assume at hand you may have a faulty device.
Yet only service will confirm such problem.
If the Device Reboots:
- Verify if it is not RAM overload.
My device is Running on Stock Rom, but Rooted so I can be able to manage my RAM, and CPU Clock (and more ofcourse).
If you suspect that is the case, and you are adventurous enough..Root the Device (Please Read about "How to" and "Risks Envolved" if you're not so experienced), and Install: "Memory Manager" from Google Play.
Set it to Optimal or Strict and to Start on Boot.
Memory Issues are most likely gone.
In Both cases there are a few more related issues.
Either Software or Hardware.
If none of the tips I said helped. You need to investigate a little bit more so we can give you further help.
Hopefully you already got this fixed.
Best Regards;
Richard
Please hit thanks if this helped. It will keep me motivated to continue helping.

Security storage app? Consumes 98% battery

I have the app android booster to monitor battery use. When I go to applications everything is at 1% and 2% but the android process "security storage" is consuming 98% battery? Does anyone know what this is? Is there a way to minimize it or can I freeze it with Titanium Backup?
Sent from my SAMSUNG-SGH-I997 using XDA Premium App
I wish I knew as it's killing my battery also, I'm thinking I'll have to reflash or even odin back to stock before I'll get rd of the battery drain caused by secure storage, I found out it's com.android.providers.security that started secure storage but not much else
I see nobody is addressing this issue, or even explaining it. Too bad, as I'm having the same issue. The annoying part is, no matter what kernel I run, the same thing happens: The phone will sit sedately idle until I want to use it, then the minute I try to do something "Security Storage" starts running and the phone becomes non-responsive for 30 seconds to a minute or two while that stupid app is running.
Why can't this app do its maintenance while the phone is idle, rather than the minute the user wants to do something, or be forced into "nice" mode (don't know if Android has such a setting, but it's based on linux and linux does have such a setting) so that it's only allowed to hog the CPU when the phone is idling.

I've noticed a lot of system resources get wasted even after removing the knox apps and enterprise and container agent stuff that comes on samsung phones. I mean, I guess its good as an option to have if you have use for it. Problem is tho, for ppl like me, its also built into the system in order to make those implementations effective and when you install a custom ROM and or kernel it causes errors. I think thats why some people dont like touchwiz ROMs and think theyre laggy. When the kernel and system are not synced anymore, crap goes on in the background that is just a waste. I still dont know much really, but I spent some time trying to fugure out how to disable some loggers and errors that were going on and were pissing me off. Here is a link to a post I ran across that helped shed some light on some stuff. Be careful tho, and if you don't know what your doing, spend some time to learn about what all that stuff does, because it's system stuff and you could find yourself in a bootloop or with an expensive azz brick http://forum.xda-developers.com/showthread.php?t=2599266

interestingly using icyfusion rom and terrasilent kernel, I cannot find this line in my build.prop. anyone else not seeing it there? secure storage is eating up at least 20% constantly of battery/cpu accord to elixir2. My battery drain continues to plague the device and I can only get about 1-2 hours of light use out of it while it continues to drain when screen is off. All I want to do is use it to listen to some tunes and I'm regretting rooting the device now. Refreshing to stock, wiping everything...formatting etc. has no effect. Has anyone solved this problem (presumably related to secure storage?) with another method?
(yp-g1 us version, currently on GB 2.3.5 stock, rooted with terrasilent kernel).

I tried CM11 which worked fine for a week or so and then all of the sudden the battery drain problem appeared. I didn't check the build.prop when on that because I decided to reflash to stock and start from scratch trying different roms/kernels. I can't shake the battery drain now no matter what I do - factory reset full wipe, you name it. I guess I could try installing cm11 again and see if it is in the build.prop then?? I just don't know how to proceed at this point.
My suggestion would be to go into developer options and take a look at process stats to see if there are any rogue processes running that you don't need. You can also download and install BetterBatteryStats app from here on XDA or purchase the paid version from the play store so that you can specifically pinpoint what is causing your device problems. Also, older devices often need batteries replaced because they wear out. I don't think the secure storage bug affects AOSP based ROMs since it is related to Samsung's Knox. Another tip would be to use a build prop editor app that has a search function to make finding things easier.

thanks for the suggestions, but it's all similar to what I've already tried. I did use Elixir2 and another battery status app to monitor things, and I have also gone through running process and disabled everything that I don't need. I did order a new battery just to check, but I don't think that's the problem. The top part of the case (where the CPU is running I presume, not the battery) is getting very hot, so there is some problem with a program or service overheating the CPU which in turn drains the battery. I just charged to full today and turned the screen off so that the device will sleep. 2 hours later, it is dead. I checked battery stats in settings and there is no indication that the device wakes while screen is off...I'm just totally at a loss. It's almost like it's a hardware issue maybe caused by a kernel or something like that, rather than an app or service. I just have no idea. Someone in another forum advised me to flash to stock and run a logcat app and post results..so I guess I'll do that. I'm worried though, because I was googling prices for ipod touches earlier today....I don't want to go back to the dark side...but I just want a device that works and I can listen to music for more than 30 minutes too.

thanks, but that was one of the first things I turned off. I only want to use the device for music listening and quick browsing/email. I shut off wifi when not using and leave it in airplane mode as well....definitely something internally wrong with the device somewhere that goes beyong changing the usual battery draining settings. Still have the logcat running and the device is making very strange noises I've never heard before...popping, screeching scratchy sounds....very strange...things just seem to be getting worse and I'm worried I'm quickly heading to an expensive paper weight situation... Battery continues to drain at 20% or more/hour with screen off. I think after this if no progress is made,...I may try to unroot the device, but I don't know if that will solve the problem and will undo the damage already done.

MB865 CPU Out of control and Excess Heat

Has anybody else had the issue of an out of control CPU?
Using the stock Task Manager, CPU usage is reported almost at 99% at times... but I get nothing to indicate usage out of the ordinary using Watchdog or other third party task managers. I am honestly at a loss for words at this point, as I can never pinpoint exactly what app is causing trouble. One minute my phone will be fine, and the next its 109 degrees with CPU being reported at 99% or 100%.
Has anybody else had luck in fixing issues like this? This is probably the second Atrix 2 I have received from AT&T, and it doesn't appear to be a hardware issue.

I was actually having a similar issue a while back, and keep in mind I never exchanged my original handset.
On stock rom, my phone would freeze up, and begin to get really hot. I would have to remove the battery to restart the phone. Now I'm a creeper user and I've been lurking the forums since I bought this phone. I've seen tons of posts about it. The strangest thing was that it was sporadic, it would happen twice in one day, then it wouldn't happen for a month, and would suddenly happen out of nowhere, completely random times of the day. Your problem sounds similar, pretty much exactly what was happening to me except mine would freeze, you're probably catching it before it freezes. I wouldn't notice it as I don't constantly handle my phone it usually sits for at least an hour or two at a time. The 'freezing' may have been a temperature failsafe. I had luck restoring the phone to factory, but would occasionally still occur, the last I had the factory rom on it, it didn't happen for 2 months, at which point I installed a custom rom.
I read lots of replies to saying that it was probably a hardware defect, but I can assure it is not. Definitely on the software side of things.
Anyways, way too long of a post I know, try restoring to factory from the recovery partition.

Ok, now this is going to sound odd, and it is, it is also a real pain in the rear, but it is the ONLY way to figure it out.
Issue is that there is an app that you have installed, that you most likely always use, and install on your phone, that does not play nice.
How to fix this:
1) Trouble shooting:
remove ALL of your installed NON-stock apps, one at a time, and check your CPU usage and heat before and after each uninstalled app, when it goes away, it is most likely the last app that you uninstalled.
2) After finding that bad app, do NOT re-install it, report your issue to the developer.
3) Find an app that is similar, and does the same thing, and try a few out, but don't re-install the suspect app until the dev has fixed the issue.

Overheat problem-p5110

I have that problem since i got this tsablet.
On stock ics,stock jb,cm10,cm10.1,all 4.x roms.
It happens when the tab is charging,and in weak use(did it only once),and generally when it is in use(very warm on top left of the tab).I manage to cool it down by using an laptop cooling dock,but it shouldnt be normal that it overheats,should it?
Thank you.
Me too...
Just same tab and it is always over +30 C° temperature and my tab isnt even 3 months old. And when i play it gets to 33-36. Even now writing this this feels warm. Try battery stats+ and check your temperature and compare to cloud. Its prettyweird what twmperatures others have. I have.too looked for solution and i hope someone helps us.
I have no problem at all with the temperature of my tablet. It's never overheated (except when I play games for a while) but then again, I do watch my apps. What could help is checking which apps start at boot. If you have to many apps starting at boot, it could cause your tablet to overheat due the programs running in the background.

I remove soo many apps every time I install a rom, and it kept heating up.
Other samsung device users report the same problem, and they conclude it is the software bug.
Galaxy s2 has a fix for that, but no fix for p5110 :/
I cant put my tab in a protective case because of this problem.Gonna wait for official 4.2(until september), it will probably feature the fix for this problem.

Horrible Battery Life

Hello All,
I have (2) N5's (one white, one black). I've noticed that battery life on the black one is extremely bad. I'm almost always near a charger, so it was quite a shock when I noticed the black one down to 37% by noon. The next day I swapped phones and never saw the charge on the white one drop below 97%. I wiped both phones and configured each identically and was able to duplicate very similar results over the next few days. This morning I decided to see what happened when I did not connect to a charger. My use has been almost nothing (5 mins of screen time, 3 hrs off battery), yet my phone is already at 81%. I notice "Android OS" is using approx 50% of the battery. I do have a few apps that run in the background and I also leave GPS, BT, mobile and wifi on all of the time, however this is no different than how I used the white one or any previous phones. I suspect this is a hardware problem, however I would like to try to pinpoint the cause to satisfy my own curiosity. Can anyone recommend specific apps/tools that would provide more detailed information about what is going on with the different subsystems (battery, cpu, radios, storage, etc) that could help me find the problem? Thank you.
Do some searching and reading.
It's your apps. Not a hardware problem.

You have a wakelock obviously. My Android OS does the same thing, but it doesnt destroy the battery that bad. My wakelock is wlan_rx_wake, and its very annoying to get rid of. Still havent found a way to kill it yet.
I've noticed if you turn the location settings to "Device only" the Nexus 5 sips battery, while the screen is off, because it isn't always waking itself 1,000+ times a day to report your location.

I initially thought the same thing; however, I did not install any apps after wiping the phone, yet the problem remains. Also, I do not have this problem on my other N5 with all of my normal apps installed and configured for normal use.

I did this... mostly. After wiping both phones (by reflashing the factory image) I did charge both to 100% before using them. Unfortunately, I am on-call 24/7 and have to use one phone at all times. I did keep usage as identical as possible. I did this by not installing any apps and charging at the same times for the same amount of time. Also, my commute and time at work/home/elsewhere was almost identical. Of course there are some things that are out of my control (call, sms, emails, etc received), however it was certainly not enough to account for the difference I am seeing. If I take the phones off the charger at 7A, and use as little as possible, the white one will be >90% where the black one with be <40% by noon.

This very well may be. How did you find out that your wakelock is wlan_rx_wake? This is what I'm really seeking - app recommendations or other ways to acquire this in-depth information. I've done some googling, but many of the apps that I've seen recommended do not work with KitKat. What I find most odd is how the white N5 with a 100% identical configuration does not have this problem.

Thank you. I suspect this would make a difference, however I am basing my expected usage on what I get with the white N5 with the same configuration. I did not change any settings on either and would like to see them similar with the same configuration. Once the issue is worked out, I will definitely take your advice and change this setting to increase my battery life.
Thank you all.
Did you download the firmware from Google then flash it in bootloader? Also you need to flash both phones to stock, Then not install any apps or settings on both so there both the same. That's a fair test.
If you can't do this, Then this thread is pointless as far as I'm concerned.

Why the attitude? You're clearly a helpful person, based on the time you spend helping others on here. If you're having a bad day or dealing with some personal issues, I sincerely hope things get better for you. If you really have a problem with my test constraints, then please move along. As a UNIX Administrator for the past 15 years, and a component-level electronics tech for 5 years before that, I can tell you from experience that the real world simply does not always provide for ideal conditions. While I agree that a 100% identical setup is preferred as a control, it's simply not an option. Even with my constraints, there is no way the number of emails and texts that I sent/received on a given day are the cause here. All that said, the point of this thread was to gain insight into how I can find more detailed information about what is going on with the various subsystems - either app recommendations or other tools. Much of the information I've found has been high-level - Settings > Battery or BetterBatteryStats (which doesn't work with KitKat AFAIK).
Thank you.
Without the 100% identical test, it's a guessing game.
I don't have an attitude, if I did, I would have told you my credentials, but I didn't think that had anything to do with this thread...
I'm not being a smart-ass buddy, and I do like to help on here as much as possible or as much as my knowledge can allow me.
Better battery stats, is for sure your best bet, that app is a must have for trouble shooting. I'm sure within a few days, there will be a update.

Bad battery on I9505. How to check if your battery is bad and more.

Hey guys,
for a few weeks now, my phone has been randomly shutting off at the slightest increase of load. Whether it be loading a YouTube video, playing the casual session of Cut the Rope (Does it count as casual when you complete all three parts with perfects everywhere in about two weeks?) and maybe Plants vs Zombies.
I've not seen similar symptoms on XDA, but who knows when it will hit the next person?
Now, I've searched quite a few forums, such as Android Central, but haven't found a thread similar to this.
I created this thread, in the hopes that it'll help some more people.
Read on if you think you have a bad battery.
Likely symptoms of a bad battery
Serial number starts with BD (Could it be short for BAD? Illuminati! Just kidding )
Phone randomly shuts off completely at the slightest increase of load
Phone refuses to power on again for a few minutes (Turning it back on usually causes it to shut off before/during boot)
The phone constantly looses signal
The phone gets extremely hot when not being used
I've had all of these symptoms and I can promise you it's a known problem.
What will happen if I don't change the battery?
Several things might happen if you don't change the battery:
The battery may explode (Leaving you with either a really big hole in your leg, or worse you might loose some bits and pieces.
The battery may leak and damage your phone irreparably.
The battery may leak and corrode your legs, clothes or what ever encloses the phone.
What can I do?
You can either go to a Samsung Repair Centre or go to your local retailer/provider.
They should cover this under warranty, no matter if the device is rooted or not.
If they don't, you CAN press charges/sue the company/provider.
Why? If they do not replace your battery, they may lead you to harm either by explosion or corrosion.
But that's a last-resort.
What I did, is following:
I called my provider (German Telekom, call them for free from your mobile in Germany under
Code:
2202
) and told them what is going on. They asked me what exactly is happening and got following response:
German Telekom Call Centre Agent said:
Oh, f*ck. Get to your nearest store and get that replaced immediately!

Click to collapse
which is what I'm doing tomorrow.
You can always use this as a good excuse to buy one of those extended batteries, but why should you? The stock battery is pretty decent.
I'll update this thread when I'm back or on my way back home and let you guys know what exactly happened.
I hope this can help someone with these issues and I can help prevent loosing a leg, or worse, different bits and bobs.
If you're experiencing this problem, and you've done something similar, let others know below!
Edit: I had a Galaxy S III lying around. It's battery fits more or less snug and works as long as you have the back panel on the phone. I'm using it until I get to the store tomorrow.
Yeah....I had the battery problem on S4 about two months ago and Samsung confirm that it was a known issue and that about 30% of S4 battery might be affected. They replaced my battery without any question asked.
See link below as well:
http://www.trustedreviews.com/news/...lems-samsung-offers-free-battery-replacements
Part of the symptoms include swollen battery as well. My battery got swollen to a point that it started pushing my battery cover and the screen out. If you want to know that you have a swollen battery, put it on a desk and give it a spin. If it rolls (with the middle of the battery touching the desk) , then you have a defective battery and you should get it replaced at no cost.
Another symptom is that your battery could go from 100% charged to 0% (phone won't be able to start unless you connect a charger) during a reboot. It will then jumped to about 80% full after connecting your phone to a charger.

Symptoms: serial number of faulty batch; swithing off while showing different load state, heating, swollen battery.
Remedy: replace the battery. By purchasing, visiting the Samsung centre or calling the Samsung Customer Help in ANY country.
So, please, read the linked thread again. Take special attention on the posts: 1; 2; 9; 12; 17; 18; 28; 29; 33; 34; 36.
So far, you were unable to find the linked in my previous post thread, what gives some interesting picture about the ... ability of searching.
Symptoms: wrong as well, because typical for DB bad battery case symptom is that you cannot turn the phone on back again, no matter how long you would wait, without putting the phone to the charger. As well, phone was not going hot (above normal level) no matter, used or not.
Finally, the phone wasn't loosing signal more frequently than normal.
"What will happen section" :, your statement that bad BD series battery will leak, explode, cause the nuclear blast or whatever is unjustified, because the battery is swelling so badly that it would damage the screen much faster. ( further info here and here - I hope you will be able to find the appropriate posts by yourself. If not - please ask, I will help you if your parents are too busy).
Furthermore, so called solutions you tried to provide are ridiculous, as Samsung knows the problem with BD batteries and replaces it without single word, worldwide (examples from threads: Asia, Australia, Africa, Europe).
Last but not least: on the XDA, there is simple set of rules, where one of them states: DO NOT REPLICATE the posts and threads, USE the search button before posting and add your comment to the existing thread before starting a new one if the similar thread exists.
so far, your thread is the 4th related with officially called back by Samsung faulty BD series of batteries.
I don't see anything wrong with this thread and am leaving it open. It provides useful information, which is clearly outlined in the OP, and may cut down on future threads being opened about it.
