Phoned Turned off by itself - Sprint LG Optimus G

So Im unlocked and flashed the Super Nexus ROM about 3 days ago. Its the first ROM to be ever flashed into my phone. Today I was on my way to school and the phone out of no were just turned off by itself? It wouldnt turn on until I connected it to the charger. Has anyone else had this happens to them?

I've had similar issues. I also had an instance where the phone was on but unresponsive. I had Ana alarm going off and it wouldn't turn off, screen was off and buttons not illuminated. Next time try holding power + vol up. Usually after about 15 secs or so it'll reboot.

Screen not timing out

So I noticed this a few days ago. I have the screen set to time out after 30 seconds. It will work for a while and then it will no longer time out. If i reboot the phone everything goes back to working order. Ive tried this with and without smart stay on and got the same results. I do not have any applications installed that would cause the screen not to time out, plus it works from time to time. Any ideas as to why it may be doing this?
This has been happening to me lately too... Don't really know what could it be.

Yes I'd also like to know as it is a bit annoying and killing my battery if I dont catch it!
This used to happen to me too. I even returned phone and it started happening again. This seems to be a bug. I flashed a new rom and it never happened again

[Q] Charging after Root/Unlocked Phone

So I used Freegee to unlock booloaders and Adri's Root method to root the phone and everything went smoothly.
Now I usually turn off my phone to charge at night and when i do this it seems that the phone goes off, but the screen is black but glowing like the light is on inside the phone.
Is there away i can fix that? I hope this makes sense.
TIA!
Why turn it off in the first place???? And I have no answer.

I can't help you, but I'm just letting you know you're not alone. Mine did that a couple of times when I was on some CM 10.1 nightlies. The phone would just shut off. I thought maybe it was just a SOD on black screen, but one time I caught it flash the Samsung logo, and then shut off. I had to press and hold the power button to turn it back on. Strange indeed. I don't know what caused it, but I would like to know. I use my phone as my alarm, and if it would shut off during the night that would not be good for the morning.
You'd get much more input if you were on a Rom on xda.
This is why I won't use a few roms....jellybam, carbon....at least until there is a dev thread on it....and a couple others.
Just my two cents!

Exact same thing with me...even the logo every once in a while...I just factory restore to stock rom with no root and no problem so its something with the software

It can be the software or the hardware. My phone keeps rebooting even though I reverted back to stock.
I'm getting the same issue with the random shutdowns. I'm on PAC-man rom. The few times I noticed that it happened was when the screen shutdown while an app was active.

Rooted Phone won't boot, can't access recovery or download mode.

Hello,
Today my phone randomly turned off by itself, and when I turned it back on, it got to the samsung screen and then went black. After I tried again/pulled the battery, it did the same thing. I can access recovery and download modes, but when I tried to restore my phone, my phone ****s off before the process can commence. Since the phone barely stays on for 5 seconds, I can't get Odin to see my phone. Please help. My phone is rooted, but I never installed a custom ROM. I'm still stock.
Try to pull the battery, then plug in the USB. You should be able to enter download mode without the restart.

Doesn't work. When I plug it in without the battery, the charging light comes on, then turns off, then the mini vibration happens. But I never get a samsung screen. Can't access download mode at all without the battery.
That did happen to me before. I'm trying to remember how I repaired it. When the battery is in, and turned on. Is it rebooting alot or stuck on the Samsung screen?

The samsung screen will come up, disappear, and then the phone doesn't do anything again. I have to pull the battery to get it to turn on again.
Have you had trouble with the USB staying connected with the PC before?

Not before this happened...
Hmm. I'm stumped. Sorry. I had the very same issue with my i777. I had the Odin screen on while I fiddled wth the USB connection at the phone until it finally stayed connected long enough to push a recovery to it. Although it doesn't appear you have the same issue. I figured I'd throw it out there. Again. I'm sorry I can't help further.

Not to my knowledge, I can still push it just fine.
There have been more than a few instances where someone would have similar issues where if would shut off after a few seconds. Most times it would reboot itself over and over, but for a few people it would just shut down.
Most of the cases I've seen, it turned out to be something keeping the button in contact causing it to trigger the switch.
Sometimes it was the button itself got jammed, others the button felt ok, maybe a bit loose, but under it it was essentially pushed in. A couple have apparently just had a bad switch or a short.
May or may not be the case here, but thought I'd go ahead and mention it.

What do you suggest doing if this is the problem?

Some people simply opened up the phone and reseated the button. Others had to buy a new button and replace themselves. Some sent it in to a repair shop to have it done for them and a couple who suspected it was an issue with a switch or a short on the board I don't think were ever able to fix it.
One guy got mad at his and slammed it on the table. After that he said it worked fine! I do NOT recommend this!!! But I have fixed stereos, VCR's, CD players, and all sorts of electronic equipment with this method! I would never attempt it with this fragile screen though!
What I recommend is that you go to a phone service centre that does JTAG, that way they can diagnose and repair the motherboard

I can't be so sure, but to me it sounds like the motherboard, if you have used triangle away before and have a clean flash counter you could send your device to Samsung for service and repair?

I was under the impression that Sudden Death couldn't happen to US variants and they they had fixed it in the updates, guess I was wrong. Gonna have my friend look at it, if he can't fix it i'll send it to T-Mobile.
when you try to access dl mode you get the option to continue or reboot, choose reboot and long press home and volume up, this will cause recovery to boot up (I sometimes have trouble getting it to boot with my problem without this method) then flash your rom again or flash a firmware package. this will at least get you into your rom for the time being. Then you can work from there.

Doesn't work, phone still cuts off before I can get into recovery.

did you try taking battery out for about a minute then putting back in and trying to boot to recovery?

Something odd..

Ok so my note 2 turns on, will boot into download mode or recovery just fine. It boots up but dies immediately upon finishing boot. (Occasionally, I can press a button or two.) I have flashed a Rom since this problem and it does the same thing. This is driving me crazy!

You on a custom rom or stock with custom kernel what was last thing you did b4 this happened?
Sent from my SAMSUNG-SGH-I317 using XDA Premium 4 mobile app
It was rooted stock with cwm. Since this has happened I have put a Rom on it was(jedi x) but it boots to the homescreen but just for a second then it reboots. It's my wife's phone and she says she got shocked by the outlet and the phone shut off oddly.

The problem seemed to fix itself (this has never happened before!) It maybe thatmy battery terminalwas a bit messed up (long story) and wasnt pushing up against the battery with enough force. Little piece of aluminum foil and a lot of cursing at unsteady fingers and it hasnt had a problem since.

I keep every phone I ever had. I don't need to sell them to get extra change for my next one. This phone quit charging for a week. Then one day it started charging again. That's when I put a sliver of aluminum foil in it to Mae the connection tighter. Probably didn't need it but the phone still works today. When is your momma gunna buy you a new phone? Better go to bed so you can get up and cut that grass.
