[Q] L9 P769 Randomly Turns Off - LG Optimus L9 P760, P765, P768, P769

T-Mobile L9
Firmware: v10g
After the phone is off the only way to restart it is to re-seat the battery.
Is this the wifi sleep of death issue? I never had this problem with v10e but you can't even downgrade right now
Please advise. Thanks.

Am not quite sure, but i guess sleep of death (sod) is an SD card issue. Remove sd card and then see if u get sod. I found in galaxy tab thread that sod was happening due to incompatibility of sd card with device. So try to see without sd card for a day or 2?

You may have a bad battery or a bad phone. You may need to have either one replaced. I have had this on devices before and it is difficult to figure out which one is messing up.
Does it go into sleep-of-death while charging? If so, it is most definitely the device.

It has not SoD'd whilst charging.
I did a factory reset and so far so good but I don't have my hopes up. The battery life has recently become quite horrendous. Today I woke up with 100% and by the afternoon it was at 1%. The best part is that I only used it a couple of times in that whole span. This is the worst battery life I've experienced and it was initially nothing like this. So is this a software issue that is causing excessive battery drain and is also causing the device to shut down? Is it a defective battery which is causing the device to be shutdown? I don't know how to distinguish between those 2 short of buying another battery which will be a dumb purchase if the device is actually the problem.

Sounds about right.

I know this is a necro-thread, but I'm actually having the same issue. I had received this phone as an alternate swap from T-Mobile because they didn't have any more MyTouch 4g slides in stock for my warranty replacement. The day I got it, it said there was a system update that needed to be run, so I did it. Starting the next day and continuing until five minutes ago, I have to pull the battery out of my phone and restart it almost every single time I want to use it. This happens on and off the charger, as well as with and without an SD card. I'm a bit at the end of my rope, and I've seen sporadic posts about this "sleep of death" issue all over the place, but without much in the way of a solution. Did getting a replacement phone solve the issue, or did you just wind up swapping it out for a different model all together?

I bought LG l9 and it turns off only when i lock the phone.I brought the phone to the service and they said that is a software problem.When i pick it up i will update you .

having same issue
my LG L9 p769 is having similar issues, it will just randomly turn off and start power cycling itself, I notice when it starts vibrating during the startup process at regular intervals. you're saying that updating the software would help it stop doing this?

Hello erveryone,
I have the same problem. I have android 4.4.2 . Did somebody solve this problem?

reboots while on GPS
It doesnt allow me to start the GPS hardware. If I disable the GPS hardware and start gmaps it works fine but when the GPS is enabled and the moment I enter the GMaps the small icon blinks for a bit and the phone reboots.
any clues ?
i think we all are facing similar problem
i had posted the following on this thread -
t=830520
"i am facing the same issue...a workaround is to remove the battery, sim and sd card for 5 minutes and then put them all back and start
although the phone starts sometimes when i connect to my computer or try to restore the backup it gets into the loop again"

Have the same problem. When I open Navigation Software, it works fine. When I turn on the GPS Satellite it reboots itself.
No ideas?
I no longer have the jit hack, but I remember reading in the thread that once your memory goes under a certain percentage it reboots. So they suggested using a task killer.
just fyi^^

Anyone found a good fix for this I cant even open a game or GPS for longer than a min, just froze and reboot on a phone call and had to leave the battery out for a bit, this has been going on for ages now and getting worse and hotter. Only just got it back from SE Repair yesterday with a software reflash despite me stating in the letter that does not fix the issue, argues half the day with SE girl who said they wont replace any parts on 1st or second return even if they know there is a problem with it, i ended up loosing it a little. Very poor from a big company, send an email yesterday to SE main office and complaints, no reply either. The shop wont replace as its been 5 months says its SE's problem, but my phone is essentially becoming a paper weight
What annoys me most is a bought a webcam over a year ago from ebay and now its buggerd 1 email to microsoft tech support and they are sending a replacement out no need to send back the current one. Came as an open box purchase and everything, but when you pay for expensive hardware thats faulty the company has no interest in a propper repair/replace
It was a problem of power management chip and power path problem probably too little vias or whatnot. You need to get it fixed at the stealer for the main board replacement. Reflashing your device won't work at all. And you have to refrain from using cpu intensive app like robo defense and charging the device at the same time.

[Q] Has your SGSII ever turned off on its own? Please add to the poll :)

Just trying to build some statistics as to how common this turning off problem is.
--------------------
PLEASE READ THIS BEFORE ANSWERING:
1) Obviously this is regarding the phone turning off on its own when its not due an empty battery.
2) Only answer with "no" if you've been using the phone for at least a week. If you've been using it for less and it hasnt turned off, answer with "No - but had it for less than a week".
--------------------
I just want to know before I send my phone to Amazon for replacement.
I've had it 8 days, so I clicked the 2nd "no". If I saw any hardware fault in a new device I'd immediately get onto the supplier for a replacement. Unless there's software at fault here (unlikely, but obviously possible) then I can't see the problem simply going away.
Hope you get it sorted mate.
Nope. Had the phone since may 6.

Everyone runs different apps and settings on their phones. Unless there's a specific hardware problem there's going be tons of variables to consider for those having reboot issues. I've had mine for six weeks and its never done anything wonky.
I returned my 1st one as it turned off a few times a day. Replacement has been fine.

Does reboot count as a yes?
I clicked yes but I am not 100% sure if this happened to me or not. Allow me to explain...
I was carrying it in my hand walking and I happened to look at the screen and it was showing the Samsung GT-i9100 splash screen seemingly for no apparent reason. When it went away it just went right back to where it was (no media card reading or anything).
It was strange to say the least but I have not seen it happen again since then and that was about a week ago and I have had the device for approx. 3 weeks now.
Does this sound like the same issue?

Oh sorry i forgot to mention this. No, reboots don't count as they're probably a software problem which can be fixed maybe with a new ROM or update or wtvr (i'm probably going to install another ROM eventually). And i'm not sure how a replacement will help with that, since I already have the KE7 firmware installed.
Just complete turn offs, cuz it might be a hardware problem, which can be solved by a replacement.
Thanks for the responses guys. Keep it up
Hmm, well i'm not really sure of anything, but that looks like a reboot to me. It might be that it turned off and you accidentally held the power button and turned it on, but since there was no card reading or anything, i think it's the "fast reboot" problem i've seen some people with on the forums. I hope it doesn't happen again

Overheating Issues

I've been having issues with this phone overheating since I originally got it. Today, about 50 minutes after boot, the battery had gone from 100 to ~60%, and the temperature was 46 Celsius. The issue is that it regularly gets that hot. Putting it in airplane mode does stop the overheating, but I can't figure out what app or service is using the radios constantly. (Another issue I have noticed recently is really slow 3g speeds, but I don't know if that has any connection to it.) If anyone has any ideas, please tell me.

Well, what have you done to it? What software changes, apps installed? One might want to hope that its a simple software fix, have you backed your stuff up and done a factory reset, if that does not work what about doing another factory reset and formatting internal SD card (and removing external), if there are still issues, what firmware are you on?
So the main thing is to find out if it is actually defective (hard ware related) or software.
As TheChronicDroid pointed out, would be nice if Sprint could help but without the original ROM on it, they may not and hopefully won't make too much of an issue if its not the original one (wouldn't you hate it if the guy happened to remember that you came in before with a different ROM and have now put it back on original).
If you have changed the rom/rooted etc you can always put it back to original, including actually totally wiping and flashing an original sprint rom that will need some updates but will be totally original (is and SBF from memory).
Good luck;-)

No SIM issue software or hardware related?

I've had this phone for about 10 days. On Wednesday morning I awoke to the phone displaying a no SIM message at the top of the screen. I found this thread in the One X forum:
http://forum.xda-developers.com/showthread.php?t=1581349
I'm guessing that since these phones are so similar construction wise the issue I'm having is probably the same. Here's what I know so far. The first instance happened after some heavy gaming. To remedy it I restarted the phone. The second instance randomly occured while the phone layed on its back. Once again I remedied it by restarting the phone. Third instance happened sometime overnight. This time the remedy was switching on/off airplane mode.
I'm rooted with bl unlocked running insertcoin 1.1.3. Anyone else having no SIM issues? If so do you feel it is software or hardware related?

Umm I did search... Hence the link posted up above. Perhaps "one x+ no SIM" is not adequate. What are you searching on where you find the discussion that was brought up before?
Sent from my HTC One X+ using xda app-developers app
As suggested in other threads, I cut out a piece of a post-it note, stuck it on the back of the sim and I haven't had the issue since.
I decided to call HTC. They are mailing a new SIM tray to try. They advised if it does not remedy the issues to contact att and have the phone replaced as it sounds like the SIM card reader itself is defective. As suggested by the rep the phone is designed to work without postit notes and something is defective which is causing the problem.

As Lloir Said this has been answered several times, including by myself. The problem is hardware related. The sim card sits in the tray loose and every so often manages to wiggle its way out. DO NOT try and fix this by restarting the phone. I am sure it will not break anything but this is not a fix in the least bit. Pop the card out re seat it and place it back in. I have not had an issue in weeks since doing this. Other recomend a postit or tape, do so at your own risk. You would feel pretty stupid if something got stuck in there.
I used a piece of a sticker and stuck the sim to the tray after getting the error for a week. This was about a month ago and I haven't received the error since.
People say to use a piece of paper or something of that nature, but I would feel pretty sketchy about removing the sim one day and the paper not coming out with it.
I was actually able to shake my phone lightly and hear the sim card rattle around. Even placing my phone flat on its back and playing music or sounds from the speaker would be enough to rattle the sim around. Definitely Hardware issue.

I've had this happen two times to me and just restarted the phone, both times happened with a couple days of each other but this was at least 2 weeks ago. Why do you not recommend restarting the phone? Is it just because its not a real fix or could it do some sort of damage to the phone?

I said right in the post it will not break it. restarting the phone does not fix the fact the card is loose hence why it happens more frequently when restarting versus popping the card out and re-seating it.

[Q] Phone keeps shutting down

Hi guys.
My phone shuts down at random moments. I can boot it up again by holding the power button for about 10 seconds. Sometimes, not always, the phone feels hot and batterylife dropped. I have been struggling with this problem ever since i got this phone. I hoped to solve it with installing a new kernel and rom. I am now on Slimbean 3.1.0. The phone was initially on XLQ6 4.0.4. This didn't change anything, unfortunately.
I have also tried:
- removing external SD
- placing a new battery (which has no room to move, in case anyone suggests the battery might be moving)
- wiping caches
The strange thing is that my friend has bought his i9100 together with mine in the same order. He is also on XLQ6 and is experiencing the same issues. Less often than me, however.
My smalband is still on XLQ6. Is it possible that this causes my problems? Or is it more likely that my friend and me simply bought phones from a bad batch or something (hardware related)? I really don't want to send back my phone. That is my absolute last resort.
EDIT: Problem solved! Installing the application "Load Monitor" and enabling the "wake lock" function has done the trick. No more shutdowns or reboots!
Anyone?
2 devices with the same issue?
I'd be at the store where I bought it right now.
I will do that when I am absolutely sure that it is hardware related. However, if anyone has a potential solution I would really like to solve this issue myself.

Same with me. change from 4.0.4 WLPT to 4.0.4 WLPY but problem still presists.
Does anyone know if changing smalband (if that is possible?) could make a difference? Because that is the only similarity to the original state of my phone. A lot of AT&T users in the USA experienced the same problems also with 4.0.4. However, nobody can come up with a solution.

If it is heating near the camera, it's facing death soon.
If it is new and warranty isn't voided, why not flashing the carrier ROM and get a new one?

Because I don't like to lose my phone for a couple of weeks. And I prefer to fix these things myself. I have seen so many topics about this on XDA and Google. There must be a solution to it.
Is it possible that these problems are caused by my modem? That is the only unchanged thing since I have had this phone.
I might have found a possible solution. I've read something on a Dutch forum about sim-cards causing these issues. So I have placed a new sim-card and the problem hasn't appeared in the last 3 days. Before that, the problem was occuring about 3-6 times in one day. It's too early to say this has solved my problem, but it definitely made a difference so far. If it keeps functioning perfectly for the next couple of days I will close this topic.
Symptoms were merely reduced. Phone still shuts down approximately each 2 days. Much better than it was before though. Why would a sim-card change reduce, but not solve the problem? This is starting to hurt my brain.

You may experience sleep of death. What WiFi chipset do you have? I had the same issue on a Murata Wi-Fi chipset.
Yup, Murata chipset. I've googled some more on SoD. I have now installed an app called "Load Monitor" and enabled Wake Lock in preferences. This should prevent the phone from going into deep sleep, apparantly.
Some portugal carrier had a problem with lte sim card or something like that.
I really don't see how a sim card can actually mess with a phone.
Maybe the enabling of some features screws it up.

In my case Samsung Service Team replaced the motherboard. My new MB has a Samsung Electronics wifi chipset. Two weeks now and no SoD.
That sounds good. However, ever since I have installed Load Monitor my phone runs fine. It drains approximately 40% of my entire battery, but it lasts easily until the end of the day.
But again, I shouldn't get too excited. Sim-card change seemed to work in the first few days as well.
Will be continued...
It has been over a week since I have installed Load Monitor. My phone hasn't shut down once. Problem appears to be solved! I hope more people will read this topic, because I have seen a lot of desperate people during my search to a solution.
The only disadvantage is the battery usage of the application. I now have approximately 40-50% at the end of the day instead of 60-70%.
