Phone locks up at 5am each morning.

I've had a SII for a couple of weeks now (new user to android) and I have flashed it to Lightning Rom 1.5. But even before doing this and also afterwards the phone seems to crash/lockup at 5am on about 5-6 occasions.
Is there any program/app I can install to monitor what is kicking in at this time so that I can disable/uninstall it?
Thanks

What do you mean by crash exactly ? Reboot ? Freeze ?
What you could do is plug your phone to your computer before it crashes, and start adb logcat, wait for the crash, and then look at the log to see what caused the crash.

It is completely frozen. I get up at 6:15am and the phone has a blank screen, but I can press a button to activate the screen and the clock is stopped at 5:01am and you cannot do anything else except turn the phone off and back on.

Maybe its the rom? Have you checked its thread? Try flashing bacm to stock. See if problem occurs.

I checked the thread but doesn't appear to be anyone else with same issue. I might try the stock ROM to see if the problem persists. Although I sure it happened once on the firmware that came on the phone (KE2 I think it was).

scheduled backup?

I couldn't find any backups scheduled. So I wiped the phone last night and applied the Lightning 1.5 ROM again and it seems to have been fine this morning..no lockups.
Thanks for the advice.

I had a similar problem with my Nexus S. It went into a bootloop at around 5am... I'm not sure, but I used to think it might be that network operators refresh their networks at that time, and a buggy radio would crash.. This is not normal, if it does the same thing with stock return your phone for repair, especially if you use your phone as your alarm!

I'll keep that in mind if it happens again..cheers. Been OK this morning so shall see how it goes.

Its done it a few more times since I did a factory reset, always at 5:01am. After rebooting the phone and checking the battery stats it appears that 'Cell Standby' has used 52% of all battery consumption and the battery drained from 100% to 9% over 8 hours. The problem also occurs even if the phone is on charge over night.
So maybe it is a buggy radio? Gonna take it back to the store tomorrow to be looked at.

[Q] Nexus 4 shuts down right after boot every time!

Hi,
I don´t know what to do. I got my phone 2 days ago. All fine. Rooted right away and used only adfree and titanium backup to restore apps.
Today out of the blue my phone shuts down. When I reboot it shuts down again right after Android booted up. Every time!
Can´t use it at all!
Tried reflashin factory und relocking but still it shuts of right after start of Android. I can get to bootloader and wipe in recovery all day. That works but as soon as android boots up it shuts down again once you reach the lockscreen.
Guess my phone has a failure but I wanted to ask here first before returning it.
And honestly I did not do something kernel or rom or OC.

Can't tell you on the N4, but my vivid, anytime it started to do what you're describing, I had to re-flash the boot.img and reinstall the ROM to stop the boot loops.

I already did a factory reste via image flash. Still no good. Once you reach the lockscreen it shuts down "powering off"

temperature issue?, there must be some hardware fault that's forcing it to shutdown after all services are loaded or a issue with battery stats.I would restore it and rma, or somehow drain the battery then recharge it

Mine is doing the exact same thing. I have returned it to bone stock but no change. Will try to drain the battery but it might take days with just the recovery /bootloader screen on!
OP: were you able to fix yours?

Hi,
I did the same.....drained battery but afterwards it would not charge again all i got was a red LED and no hint to fix it helped me. Phone is completely dead.
I already ordered a replacement unit and am still waiting for it

Same deal with mine. It worked fine for 6 weeks, it was completely stock the entire time. I have sent it away for RMA.
---------- Post added at 05:31 PM ---------- Previous post was at 05:28 PM ----------
Also, when I told the CSR what it was doing they had absolutely no hesitation to process the RMA, they didn't even suggest a factory reset, I'm assuming this must be a known issue.

Same issue/ diff reason
I have the same issue with starting up the phone and automatic shut down.
I dropped mine in the water, however. Nothing seems to be wrong with it other than this auto shut down.. I was thinking that the battery was possibly fried. I ordered a new one to see if that would fix it.
Mine is also rooted too, however. This was the issue of the above original post. If there is a solution for either of my issues, I would greatly appreciate it.
thanks!

Hey dude this the new battery work? exactly the same issue here.

Nexus 4 shutdown after boot
Hey guys
I tried replacing the battery and the issue still persists and also tried a few different roms including stock but it does the same thing.
My N4 is not under warranty any more. Has anyone got this issue fixed...??

[Q] Nexus 4 -- Only working while plugged in...?!

Yeah... I'm not great at titling... Anywho...
I've come across a problem, of which I'll attempt to go through everything I did that leads to the point, which is; my Nexus 4 doesn't turn on without being plugged into, either the wall or any PC.
So my phone crashes, solemnly (probably because I have Cyanogen on my phone), but lately (lately is in this past week), it's been crashing 3-4 times a day. Then, a few days ago, I was on it and it crashed again, this time, it wouldn't turn on -- my brother was (and probably still is) under the impression that I bricked it -- I would still be thinking the same but seeing as the phone turns on whilst being plugged in I'm wondering if the battery is shot, the hardware is shot, they're both shot or something more undesirable is happening.
I'm not blaming the app for this, however, the frequent crashing did start to happen more violently after I installed and used "Google Camera" for no less than 5 minutes -- at which time, I uninstalled the app and went to the Default Camera App, only for it to also crash the phone, thereafter, the phone just started to crash no matter what I did.
The phone also chooses when to shut itself off; sometimes if I unplug it, it'll turn off immediately, other times I've noticed it'll actually stay on for awhile (the longest its gone so far is 5-10 minutes). I was playing around with wallpaper when I decided to see if I might be able to use the camera, to my dissatisfaction, the phone crashed -- I noticed this when I looked back at the screen.
So now, for the last 18 (give or take 4 hrs) hours, I've been using the phone 'normally' whilst plugged in.

Have you tried to make a clean install and not restoring anything to check if that helps? If that doesn't help I would try flashing a factory image.

Yes I have tried to make a clean install, with a different OS as well, CyanogenMOD's take on Lollipop 5.1. The phone still turns itself off though.
What is "Flashing a factory image" mean?

You download the full stock ROM from Google, and use fastboot to flash it. Here is a guide on how to do it. http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312

If you want a 100% clean flash, just download the factory image and flash it by executing the flash-all.bat (you are using windows I guess) script. It might be necessary to reboot into the bootloader first.

Tried this, didn't work.
My phone has basically been flashing red for awhile now and it doesn't turn on at all.

Your battery is dead, same happened with me 3 months ago.....
I took it to service centre, they just changed the battery (ask them specifically otherwise they will wipe data too, internal included)
Overall it cost me INR 1200 i.e approx $20

Yeah, so I figured.
My father and I just replaced the battery with a Tablet's battery. Although probably not seen as proper. If it works, why fight about it? Haha.
Thanks.

Galaxy S5 Reboot loop

Hi all,
My galaxy s5 is stuck in a reboot loop. It started doing this today around 12:18pm and I can't get it to stay on long enough to back up my data. I took it to AT&T and they basically did nothing but tried a different battery and booted into safe mode. Neither of those options worked. I took it to best buy and the tech installed the latest updated and flashed the ROM (I believe). Still didnt work. She believed the issue was with the battery but didnt have any new ones there to test so I went to batteries plus and tested a brand new battery, still is rebooting. I am home now and just wiped the cache in recovery mode, still not working. Is there anyway at all I can get this phone to turn on long enough to backup my data? Any other commands I can try to clear whatever is causing this? I was not using my phone when this happened. It died at 15% which I didnt make too big a deal of because I know the battery has been weakening, but when I charged it up for a bit then turned it on, this problem started. When I turned it on, I had a text message coming through and then it restarted. As I was able to get it on for a bit that same text kept coming in over and over again so I thought maybe something with the messaging app and I disabled that all together but the problem remains. I hope someone can help me out here. Thank you.

SOLVED: Samsung Galaxy S5 Reboot Loop
I figured out a workaround and I take full credit because this creative solution was no where to be found on the internet nor did AT&T, Samsung or Best Buy offer any other alternatives aside from wiping the device. This is what I did:
I booted back into Recovery mode and looked through the logs for any indication of what was happening. My assumption was that it was a driver error and so scrolling through the logs I saw an error that said something like fail psy battery. I immediately think maybe its the drivers for power so I thought I'd see how it would respond if I put it in Ultra Power save mode. Thankfully the phone stayed on just long enough for me to put it ultra power save which did work. The phone stopped the reboot cycle it was stuck in but I still was not able to back anything up since the Ultra power save disabled the USB drivers and port. I let it charge up overnight in ultra power save and said I would try regular power save mode in the morning to see if that would also work but this time allow me mass storage access. Well, that worked! I put it in power save and I am backing everything up now as I type. I've got all my pics and now just letting samsung switch do its thing to perform full backup. YAY! I WIN! Hopefully this helps someone else that may have this problem and have tried everything else that is recommended for solving this issue.

Don't really get it, what cause the boot loop in the first place? And you are flashing back to which rom?

I don't know what caused. I wasn't using the phone when it started. I hadn't downloaded any new apps and I wasn't messing around with the OS or system files. The phone battery died at 15%. I plugged in the charger and disconnected when it was at about 28%. I powered the phone on and there were a number of text messages coming through from my friend I was going to lunch with. I opened that message and noticed the text was duplicating itself then it rebooted. Each time I powered it up and got in for a bit that same text was coming through or trying to over and over again. So, I don't know what caused it but I have all of my data backed up and I am going to wipe it now.
Also, the Best Buy tech flashed the ROM so I am not sure which version or anything like that.

Help! Bootlooping out of the blue for NO reason

So... For no explainable reason my phone has gone into a bootloop, simply from me attempting to restart the phone.
Details of anything I can think of that might be related are below. I need a genius to help me A) figure out WHY this happend, B) help me figure out if there is a way to (non-destructively) get out of this bootloop (i.e. NOT having to do a factory reset), and / or C) tell me if there is a way that I can perform a full system backup using ADB, Fastboot or Odin with a phone that can't get past recovery or bootloader without going into an endless bootloop. I'm not a lazy guy and normally take the time to research problems and figure them out on my own, however at present this is my only activated phone, it's almost 11pm, I have to be up and out the door at 6am tomorrow, I will be judging competitions all day and will not have any opportunity to do anything about this until late tomorrow... In the meantime, I need a functioning PH1!!
My PH1 is the Sprint variant and I have not rooted it nor have I unlocked the bootloader. The only thing I have "done" to the phone is to sideload the latest OTA, NMJ32F (the day it came out, over a week ago, and it's functioned perfectly since that update). My phone has been in use throughout the day today with no difficulties. I went into a building with very spotty service for several hours this evening. On the way home, I noticed that I was stuck in 3G service, despite being in an area I know has good 4G/LTE coverage. I also noticed an unidentified icon on the status bar, a rectangle, which was located (I believe) to the right of the battery icon. It looked like a rectangle, perhaps representing a screen, or a phone? IDK. The other item of note is that I did sign into the guest account on my phone so that my daughter could use the stopwatch for timing competetion events without tampering with anything. She didn't drop it or get it wet or anything along those lines... she used it to time events, returned it to me in perfect shape. I logged out of the guest account, back into my account, rebooted to try to get the phone back into 4G service, and boom, I'm stuck in a frigging bootloop for no apparent reason.... And I'm about to lose my mind over this.
I CAN get into download mode and into recovery mode by holding the appropriate button combinations when it loops, but from there whether I power off and power on again or whether I select reboot from recovery menu, it continues to loop...

Well folks, still strange, still unexplained, but I had to bite the bullet and factory reset, just can't afford to wait. I'm still open to any thoughts on what might have gone wrong though I suspect we'll never know. This phone has been a bit buggy from day 1, things like BT randomly shutting off, VoLTE wouldn't stay enabled, etc... Hopefully this is the last time this happens. Still love the phone though!

So I am running O beta rooted and last night this happened to me. I ended up going into fastboot and starting OS through there and I had no issue with the reboot bootloop. However, last night I went to bed with a phone @ 75-80% and woke up 6 hours later with a dead phone. Charged and rebooted this morn and everything seemed normal today. It was super wierd

Had to return mine for this very reason. Less than a week in service and went into boot loop. The reboot happened after it lost all battery power (corrupt filesystem?). Several factory resets did nothing to fix it. Removed the SIM. The phone was also fully charged. Did not try ADB as it was brand new and a return was the safest easiest option.

I am stuck with the same problem, and this is my second phone already. This one doesn't stay on long enough even for an attempt to factory reset. I will send it back again, but I have no hope. Time to cut my losses and move on. Going to Pixel. And I sooo wanted Essential to succeed!

interesting.
If it's your second phone, have you looked at what applications you install?
The probability of getting two bad phones is pretty slim unless there is a major manufacturing flaw.
Not saying it can't happen, but it would be unusual.

Could it be due to Encrypted Data partition?
It once happened to me on a Huawei Mate 2 which I encrypted data and battery dead, then bootloop.
If that's due to corrupt encrypted partition, there seems only other recovery mode can help you get some files back.
