Has anyone experienced any spontaneous reboots on their ZL yet?
Mine has done it twice, both times while doing things related to Google apps or accounts. The first time my phone rebooted, I was actually adding my Google account after a reset to fix the notification LED issue. When I unchecked the option to backup and restore my Google account, my phone blinked the xperia logo, then rebooted (Sony logo, xperia logo, boot animation then done). It was a very quick reboot.
The next time, I was installing apps from the Play Store. A bunch of apps were queued up, downloading and installing over Wi-Fi. I hit the home button, then was about to open up a folder to check my Gmail app settings when again, the phone blinked the xperia logo and proceeded to reboot. When it was done, it continued to install my apps as queued from the Play Store, as if nothing happened. It hasn't done it since (of course, this was only a few hours ago).
My phone is not rooted & I have not messed with the bootloader unlocking or anything. It's 100% stock while I'm evaluating it against my SGS3 for a potential permanent switch. I've got the US C6506 model (black, on AT&T -- LTE is working fine).
I really, really like this phone so far, and I'm just hoping that these two reboots were a random oddity, not to be repeated.
Interestingly, I actually fully set up the phone yesterday evening, but when I discovered I had the notification issue, I reset it this morning and re-did all of it. The phone did NOT reboot at all yesterday in the 4 or 5 hours I spent playing with it, either. It sat in standby overnight without incident as well -- all prior to the reset today & the 2 subsequent reboots.
I guess from here it'll be a waiting game to see if it does it again, but in the meantime, I was curious if anyone else had seen anything like this with their ZL.
Yup, seen it twice myself. First time, I noticed that it had rebooted when I couldn't find any previously running apps. The second time I was in the Settings screen when it randomly rebooted. I was just about to click the Display setting when this happened.
I'm just running the stock ROM on the C6506 model. I'm keeping an eye out on it and will see if there is a pattern.

Thanks ... in some ways it's good to know, and in others, it worries me. I hope it isn't a pattern, though. Thus far, I've used the phone since the two reboots without incident (music playing, bluetooth connections, and phone calls).
EDIT: A third reboot. This time I had just updated a few apps in the Play Store, returned to my home screen and was about to turn my Wi-Fi off when it rebooted. One common thread thus far is that my Wi-Fi has been on each time. I have no idea if that's related or not, though.
I have been using mine for 1 week and have not had any reboots. I am using the hspa version (c6502) and I am a heavy user
Seems to me that the random reboots are isolated to 6506 models. I haven't had one single reboot in the past week I have been extensively using mine (6502). However, while I was on CM10, my phone hung and rebooted like hell.
Yeah I'm c6502 aswell no random reboots.

No reboots on C6502
Same here, have been using my ZL (C6502) for the past 22 days without a single reboot or freeze. Heavy usage for last week or so (wifi on all the time). I too think this and the low call volume issue might be specific to C6506 (LTE) version.
6502 here as well, no reboots so far and I'm rooted. Been about 2 weeks.
I'm starting to think this issue is unique to me and/or my phone -- at least my specific case. Actually, I'm glad for that, because I love this phone.
I realized I may in fact have memory card corruption. I'm going to explore that further, because I had some serious issues with my SGS3 corrupting microSD cards. I thought it hadn't done it on my current card, but I have discovered some corrupted sound files on it, so I think I'm going to do a format of my microSD and see what happens.
Thanks for all the input, folks!
I had some reboots in past one week
using since March 10th
today itself had 2-3 reboots
one more thing is had blank screen during a phone call also
we need Roms for this device I never understood
why there is so much delay in release of custom Roms
Once,
but not sure it was rebooting. Cuz the screen went blank. Then i had to press a tiny yellow button that says off near the sim slot. Then it came back to life. Plus my wake up button is kinda hard to press. Do you guys hv that problem?

I wouldn't call that a reboot, at least not in the sense that I was seeing them. That's more like a freeze that would require a battery pull on a phone with a removable battery (I used to have this all the time on the Samsung Captivate).
My ZL was rebooting fully right in front of me (screen goes black, then the xperia logo, followed by the full normal boot sequence, just very rapid -- the boot animation is shorter than a cold boot).
Note -- I have not actually fixed my memory card yet, and I have not seen any more reboots. I'm nearly a full day on my current battery charge, too.
I have the C6506 also, and I get numerous random reboots also. I did get few logcats, but I have not seen any revelant info that causes the random reboots. I replaced my micro-sim, thinking it may caused modem panic reboots, but that wasn't root of the problem. However, I did notice that the reboots occurred less without micro SD card, but I haven't completely made that conclusion yet (I want to listent to my music!).
I also have a 6506 and have been experiencing some kind of reboot. Not a full reboot that the OP has been talking about, but one where my screen just turns off. At first I thought better battery stats was just having issues as my stats would end up all out of whack for no reason. Then today the screen shut off while in use. I only had to push the power button to get back to my lock screen. But again my stays were all out of whack. I'll have to pull the log later but I hope this is is just a software issue.

Interesting. I've replaced all my corrupted files on my microSD card as of now, and so far, aside from that first day, I have not had a single reboot of the kind I saw before. Actually, no reboots at all, and my current uptime shows it (111 hours).
What happened to me was I had had a bad microSD card in my SGS3 -- files would become corrupted with time on it. I finally replaced it with a new one, but apparently when I copied my data back to it, I inadvertently copied a few of the corrupted audio files (notification sounds, actually) but never noticed it. I realized this when I was resetting my notification sound for text messages and heard the signs of corruption in the file, and so I began to think my phone had been responsible for the corruption. I know now that that can't be true -- otherwise I'd have some corrupt photos as well, and I don't. Only a few select sound files were bad, and because I keep regular backups of the contents of my microSD cards, I just copied the wrong ones (d'oh!).
Of course, I've had random reboots on android devices before (Asus TF101), so I'm quite wary of them -- if I see anything further, I'll post about it.
I looked at the log and saw nothing conclusive that would be making my screen turn off. I also checked my up time and it hasn't reset, so I know it's not a true reboot. When I put my SD card in I just wiped it from the phone. The only thing I put back was music files. Thinking about that now it wasn't the clean start I usually give my phones. So I just wiped the card again and we will see today if anything happens
C6503 here and I've been getting a couple reboots a day since I bought it. 2 days ago I used PC Companion to solve another issue (random loss of network signal) by reinstalling the phone software and that seems to have fixed it. Unfortunately the random reboots are still present.
I don't use any SD card at the moment.
I've now been using my ZL for a month or so, and since that first day when I made this post, no spontaneous reboots at all. I have no idea how or why, they just stopped on their own.
Twice this week my alarm didn't go off (luckily I set a backup today) because sometime throughout the night something happened. When I woke up the phone was frozen on the yellow Sprint Spark startup screen. I needed to pull the battery and everything started up fine. I updated to Lollipop about 2 weeks ago which is where I'm guessing the issues stem from.
Is there anything I should try other than restoring to factory and starting over? I'd prefer to not have to wipe everything from my phone but these issues are becoming problematic. I am not rooted.
Thanks.
You answered your own question. You need to try a factory reset. Problems happen when you upgrade to new software without wiping.

Dschachm is correct. Then if you root and install TWRP you can back it up with all of your apps and data. So if there is ever a problem again, just restore and done.
So I ended up doing a factory reset and while the phone certainly started running faster with better battery performance after the reset I'm still having this issue. I would say it occurs 2-3 times a week. It has only occurred overnight which is typically when I charge my phone so I'm pretty sure it is related to being left connected to the charger. The majority of the times I will wake up with a dim yellow Sprint screen and everything else frozen though occasionally the screen will be black with the led notification light red. In both situations the screen will not respond to any button pushes or holds and I need to pull the battery and then everything will start up fine.
Does anybody have any suggestions here on what I should do? I guess I can try and restore one more time and see but I don't really know why it would be different and it is certainly a pain to keep restoring the phone and losing all my settings. I definitely don't want to root now since I believe that voids the warranty and if I can't figure anything out with this I'll certainly be requesting a new phone from Sprint. Before I start dealing with Sprint though I thought I would check here first. Through all my searches on the internet I haven't seen anyone else complaining about this problem.
Thanks.
I've gotten the sprint yellow screen and nothing else.phone doesn't turn on? When I try turn it on after removing batteryou I get the android figure and phone turns off? How can I reboot or start the phone..?and can I save my contacts?
Hello!
Everything was working fine until my phone started acting up about 6 months ago. The screen began to become unresponsive, apps crashed when switching between them and random reboots occurred frequently. I thought back then it had to be software related, so I completed multiple factory resets, and completely removed everything on my phone. It became slightly more usable, but these crashed and random reboots still occurred.
Last week, my phone continued to reboot, but a new problem occurred-it no longer would turn on after the reboot. I tried plugging it into the wall, pressing the volume down + home + power to force bootloader mode, but it wouldn't turn on at all. The fix was I had to remove the entire case, take out the battery and put it back in the phone. After that it would turn on, but only for a few minutes before another random reboot occurred and I had to remove the entire battery again. My phone is now virtually useless as I cant before even the basic functions, calling and texting without it becoming unresponsive or shutting off and not turning on.
I narrowed it down to the eMMC chip. I am almost certain that is corrupt, because during some of the reboots it would fail and throw me into download mode with the error:
mmc0_read_fail
or something along those lines. My last attempt at recovering the phone was to the stock rom PE2 with a PIT file (I had created before I started flashing custom roms). Each time I would attempt to flash with ODIN it would result in a:
mmc0_write_fail
However, I was finally able to get the PIT and PE2 firmware to flash. Now I have a half-working phone that will randomly reboot still and in order to turn it back on, the battery has to be pulled out for a minimum of 15 seconds.
New Issue I just noticed: When the screen turns off when the phone is inactive, it won't turn on again after pressing the power or home buttons. Only solution to this is once again, pull battery and hope I boot into system again.
I am pretty sure there is no fix to this problem on the software side, but let me know if you have a suggestion! Thanks!
Same situation. This thing is a lemon!
Sounds like hardware failure.
Replaced the battery yet? My original didn't last fifteen months before it started shutting the phone down. It's the first thing I think of when someone reports having to pull the battery.
Are you checking battery capacity before the battery pull by plugging in when it shuts down? Mine showed 0%. Before the shutdown, it may have indicated as high as 30%. It gets worse.
You didn't mention capacity when plugged so I thought I'd ask.

One of my note 4 had same issue. Its a hardware issue. I was able to get the phone working by using a heatgun on the motherboard to try and reflow the solder on the chips. The phone works like brand new after the heatgun but the phone would only work for like 3 or 4 days before crapping out again. Ultimately ended up buying a used motherboard on ebay with a clean esn and its working perfectly again.
My wife's Note 4 started the random reboot thing and screen being unresponsive thing last week. She said it randomly started after installing Snapchat, so she uninstalled it hoping that would fix it. It didnt. I put a new battery in it thinking the original was bad, but still same issues. Then did a factory reset but that didnt work. After a lot of searching I stumbled on to someone who mentioned downloading an app called Wakelock. I did and phone has been running smoothly for several days now.
I also recently did the most recent update hoping that would fix the issue, it didnt but during the install I did get one error of emmc read failure or something like that. May just order a used/new motherboard just in case.
Just be careful when swapping out the motherboard as it essentially is taking apart the whole phone including the removal of the LCD.
My Note4 has developed a weird issue where it will be on just fine for like 5-10 hours then all of a sudden it will show the Verizon logo full-screen with nothing else and be unusable. I need to pull the battery to fix it.
Q1: What the heck would cause this? Only changes Ive made were using the new GearVR and sideloadVR, not sure if related. But seemed to have happened several days after installing them, not at the same time.
- I use synapse and have tried undervolting thinking it might be overheating. No change. Put it back to normal.
- Happens with both the standard battery and Zero Lemon battery.
- Happens when in or out of power save mode (black and white screen etc)
Q2: If I factory reset, will I lose root? Note: A software update has been downloaded and its been asking me every day to install it and I always decline.
I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?
I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.
I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:
have you downgraded?
and can you help me with my problem?[

I'm downgrading to stock 5.1.1 right now. I'll keep you updated. I placed an order for a Galaxy S7 Edge International Version (G935F) yesterday.

can you downgrade to Android 5.0.1 and help me with my problem?
its something completely different to this topic
I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.
Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)
Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.
My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.
Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.
Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.
Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.
