Anyone know what's the actual cause to fix without the app?
[Galaxy Note 4 Q&A, Help & Troubleshooting] Chris Kerry:
Greetings.

My problem was random reboots. Really exasperated me. Sometimes several hours between reboots (though at least one within 36hrs). Other times, several reboots within a few minutes. I tried everything. I got a 2nd battery. Same thing.

However, I realised that clearing the cache (in Recovery) and changing to a resting cold battery (simply swapping between my 2 batteries) bought me many hours of peace before another random reboot. I still searched for a lasting solution, since I was dissatisfied with the above "solution". Therefore, I took the plunge & explored non-TouchWiz options.

I completely formatted my System partition (not Internal SDCard/Storage nor Ext SDCard) and cleared Cache and and Dalvik. (I first backed up EFS & Modem; I ignored backing up the TouchWiz ROM - was pissed with it).

I downloaded a CyanogenMod-13 ROM, the one by RaymondFX...

Viola! No more random reboots. Significantly better battery life (especially at rest). More beautiful. Much more theme-able, even accepting a mix between elements of different themes (eg, using ones Status-bar theme, a 2nd's general theme, a 3rd's system-font theme and possibly a 4th's boot-animation theme simultaneously. The stablility was what pleased me the most. The ROM sizes are 5-8 times SMALLER than TW ones thus easier to download, update & try options...

Sure I lost access to Samsung-specific apps, but I only ever used the s-pen ones (never its Note: better ones on Play Store) when on TW. Now on CM-13, I sought out alternatives for the Samsung Spen apps from the Play Store (eg, CM SPen & Note Buddy; some like GMD even extend on the capability of the Stock Spen prompts). It still fast charges. I can use the Fingerprint lock (though registering each fingerprint is tricky & requires speed at its last stage of setup).

I'm grateful for the existence of CM & alternative AOSP ROMs (instead of just Stock & Other TW options).

I've been on RaymanFX CyanogenMod (more accurately, erickwill's updates) for over a month now. No more random reboots.

I'm very disappointed that the manufacturer's own software was the cause of my pain all this while prior to discovering RaymanFX (& erickwill's) CyanogenMod.

Hello all

Since the upgrade o MM, my battery was getting worst and i thought that a replacement wiill solve the problem since it have almost 2 years with intensive use, but so far in didnt get a new one. Was also getting some random reboots and crashes, but after reboot phone works good. But now, every time he crashes, even with battery level at 100% or 60%, he dont start. Will go the point to insert Pin, and crash again. The only way to get in to be working, is pluging charger, insert pint, and then remove charger, until next crash obvious. Try to format the phone but problem remains. I think its battery that some how, dont have power too boot and maintain phone on, it will crash with heavy or normal apps and usage, just like browsing or receiving calls. Anyone experienced something like this? Thanks

Update: Went to buy a new battery. At the store, the guy mesure the voltage and was giving 4.08v when it works at 3.85v causing the . Got the new one and works flawless.

I've been having the same problems with my note 4. Reboots, freezing and lag and had an eMMC read error one time. Started a few weeks after the MM OTA. Factory reset didn't fix anything and I tried the Overdrive ROM and still had issues. I'm surprised how many people are having this problem.

Being in the same waters as you guys

Hello everyone,

I have been sailing in the same waters as you guys. Here is my story and how i might have fixed it.

My Device: SM-N910F

Android version: 6.0.1 (Stock)

Security patch level: July 1, 2016

Baseband version: N910FXXU1DPB1

Build number: MMB29M.N910FXXS1DPG1

My knox counter has been tripped twice because i had tried to root it in the past (unseccessfully i might add)... but oh well... i reset the phone to factory settings reapplied the updates and everything was okay... until a couple of months ago when the phone started rebooting/freezing(-and then rebooting)/giving me errors like "the app isn't responding" then reboot. So i armed myself with a lot of patience and i did a lot of RTFM; Besides the fact i have never understood how you root this gooddamn phone i have found that the latest firmware updates are most likely the cause to my problems. I tried to install several ROMS, but the was no way my phone was booting correctly. I have tried several procedures and if you google something like "SM-N910F rooting" you will come a cross too many guides all telling you to do a different thing or to flash different firmwares so after like 4 hours of tinkering i decided to go back to the stock rom and/or go buy a new phone ASAP. Although i had notice that after the very first stock FW flashing the phone didn't freeze or reboot and believe me: i got errors even at the first configuration screens while on other roms. So today i flashed it back at the firmware i posted here and so far so good. I have still got some freezes, but they are like 3 seconds long freezes so no big deal and i noticed the battery drain has increased (more than just a little bit) but at least it doesn't randomly reboot anymore. I will keep you posted if i have news but i strongly suggest you try this procedure if you can.

P.S. i factory reset the phone everytime i flash new firmwares. So i will start installing apps soon and keep you posted if you wish.

Update 2016/08/05----

It rebooted after few minutes, but it's much less frequent... is there a way to access the phone logs?

As said earlier, fingerprint works: it's just a bit tricky to do the initial registration (you'll need to be be fast in submitting the last step of the validation process). Afterwards, it's usable, even after dirty flashing newer ROM versions.

I personally haven't encountered bugs but 2 reported bugs are: 1) Bluetooth calling seems to echo / not clear (normal calls are OK, random issues disappear when touch sounds are enabled) 2) sending SMS claims not to have sent (the mesage) but ACTUALLY sends.

I've had the exact same problem with the lagging/freezing/restarting. Thanks to someone's suggestion on here, I downloaded the wakelock app and my phone seems to be working fine now. I still think something is wrong with my SIMS card and will try to have my carrier replace it to see if it fixes the issue.

Been using the wakelock app for the past 3 days on stock MM rooted rom and the phone seems better. No more freezes or reboots, battery life hasn't taken a huge impact. This will hold me over until I can get a new phone
[Galaxy Note 4 Q&A, Help & Troubleshooting] golden_m:
same here, phone is up and running with no issue since i've installed the app (about two weeks now)

however, if i restart the phone, it does not turn on...need to unplug the battery and wait about 10 minutes before i can plug it in and restart.
[Galaxy Note 4 Q&A, Help & Troubleshooting] The Sponge:
Doesn't anyone find it weird that all of our Galaxy Note 4s began having this issue around the same time? This started happening to me about 2 weeks ago as well. I've tried reflashing my pit file, erasing NAND, downgrading to 4.4.4, using Smart Switch to recover and go back to 6.0.1. This is so frustrating.

The WakeLock app works, but it's not a permanent long-term fix.
[Galaxy Note 4 Q&A, Help & Troubleshooting] skinnyaznkid:
It is strange. My note is almost 2 years old, so it's like there was a timer on the phone that breaks the phone so it forces you to upgrade your phone (note 7?). I had some computers that would break the day after the warranty was up
[Galaxy Note 4 Q&A, Help & Troubleshooting] The Sponge:
Yeah haha. Well, atleast Wake Lock keeps it working. I need this phone to survive another 2-3 years before I can get another phone. :crying:

Problem is the emmc with wake lock you have a solution for a small time.

My note 4 now (after weeks with wake lock) don't boot.

I think they had too much write circles for the emmc so they damaged it.

There are so much note 4 users out there with this problem.....just look at eBay how much seller have a defect one....

forced to restart to restore data

Hi folks this thread has been extremely reassuring and useful to read, much more helpful than the angry but useless conspiracy rants elsewhere on the web. Thanks to everyone who's reported what works and what hasn't.

I bought a SM-910G second hand a year ago and was using it as a wifi tablet until two months ago, when my S3 finally kicked the bucket (and I was tired of the subpar camera). The usual problems started kicking in a month ago and I've been doing all the interim fixes, am weighing options re: Motherboard replacement (local cost 87 USD - prob. used mobo though).

It's fine for now if I don't restart... BUT! I appear to have really poor reception on this phone here in Singapore (where it was originally sold). It constantly drops out. And the worst thing is once it drops out (which it invariably does), I can't get mobile data back until I restart the phone. Curiously enough, however, mobile data works flawlessly in Australia of all places - even on a Singapore modem.

I've tried the latest Singapore modem (N910GDTU1DQD3) and bootloader (N910GDTS1DQE4) for Singapore, as well as the latest Australian modem (N910GDTS1DQA1) and bootloader (N910GDTS1DQH2) for Australia and... again, same thing, data works for a while until it suddenly doesn't, even while staying in the same spot, and the only way to get it back is restart - which often means pulling the battery these days. :/ it's really frustrating having to pull off the case+back+batt in the middle of the city, and I really would like this phone to last as long as possible before replacing the mobo.

TLDR: How can I stop needing to restart the phone to get mobile data back when it drops off?

For reference I'm running the latest build of RR (5.8.5 RC4) on carrier SIN.

Any help would be hugely appreciated!!
[Galaxy Note 4 Q&A, Help & Troubleshooting] nicholes:
I changed my MOBO (purchased from aliexpress) but my new mobo also was heating a lot so i sold my note 4 and i am now in search of some new phone like note 4 ,, so think before you plan to change mobo once again . hope this helps
[Galaxy Note 4 Q&A, Help & Troubleshooting] SteveRiley:
Try enabling then disabling airplane mode.
[Galaxy Note 4 Q&A, Help & Troubleshooting] phone_etix:
I tried doing that for ages - used to work with my old S3. Sadly doesn't seem to do the job with the note 4.

I've tried trawling through logcats when it happens and some common lines seem to be:

D/csd_client(466): csd_client_error_cb: error -2 cb_data 0xac54b068
D/csd_client(466): csd_client_error_cb: MDM reset

followed by a whole bunch of csd_client disconnection messages.

Then I get the following recurring messages (not necessarily together):

E/csd_client(466): csd_service_init: Check modem power up with MDM reset !!!
E/PhoneInterfaceManager(1798): [PhoneIntfMgr] getIccId: No UICC

Also noticed this popping up from time to time:

E/ (982): E/open failed: /dev/mdm: No such file or directory

I also constantly get this even when it's connected:

E/BatteryStatsService(982): modem info is invalid: ModemActivityInfo{ mTimestamp=0 mSleepTimeMs=0 mIdleTimeMs=0 mTxTimeMs[]=[0, 0, 0, 0, 0] mRxTimeMs=0 mEnergyUsed=0}

I can't make much sense out of this, I'm afraid, but I just cannot get data back without restarting, and that might be the dealbreaker for me... I'd be willing to extend the life of this phone a while longer by replacing the mobo, just until I move out of this country in a few months - but if it spends most of the time as an unreliable WiFi tablet, well... :(

9 in 10 times when I try to reboot my phone, it crashes and never reboot unless keep it in freezer for 5 minutes (deep freeze -20C)

Lately I have discover and use this app to get things done.

https://play.google.com/store/apps/details?id=simple.reboot.com&hl

I use it to mainly soft reboot phone, which is not as hard as reboot(where bootloader is involved and crashes)

Give it a try if you want.

Use it to soft reboot your phone, this will restore your DATA back and maybe wouldn't crash.
[Galaxy Note 4 Q&A, Help & Troubleshooting] phone_etix:
Yep, I've tried this several times with Resurrection Remix's soft reboot function - doesn't crash, but doesn't reconnect to data either. Worse still it doesn't detect the sim card :/

Hi everyone, im having the same issues on my Note 4 too (but in my case, the problem starts only at some battery level point..Yesterday it was 75%-->50%--->30%.. don't think its the battery because i've changed it 6 months ago, because the last one was 2 years old.). My phone is rooted and its running on Android 6.0.1 (i take my time with updates haha), i didnt use any custom ROM. Any suggestion about how to solve this frustrating issue?
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Most likely the battery percentage is just a coincidence - If your phone is starting to succumb to the emmc Failure all the new batteries in the world won't fix it - The only real solution is to replace the motherboard ?

If however it's not the beginning of the emmc Failure - I'd Factory Reset - Wipe Caches and see if it helps

Sent from my SM-G955W ??
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
So in order what should i have to do is:

-Wipe Caches

-Factory Reset

-Buy and mount a new motherboard

And of course check at each step if the issue was solved before moving to the next one.

Correct?
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Yeah I'd start with the simple stuff - Factory Reset and Wipe Caches - Reboot and see how your phone behaves - From your previous post I believe that you are also running the stock firmware with the stock kernel?

If your phone is at the beginning of the emmc Failure you will typically start to see the phone Reboot and sometimes Boot into Download Mode spontaneously (This is almost a sure sign of the emmc Failure) - Once this begins to happen it can take anywhere from a couple of weeks to a few months before the phone will not Boot unless you put it in the freezer (yes I said freezer) - At this point you can decide how you want to proceed - Replace the moment or get a new phone ?

Sent from my SM-G955W ??
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
The fact is that im supposing my problem is caused by emmc Failure, because my phone keeps rebooting for like 6/7 times (each time the boot procedure stops, the phone just goes off automaticcally, like if someone has just taken out the battery from it between the first interface, (the one with just your device name) and the one with the SAMSUNG logo )...if the weather is good outside , then maybe it wont do that anymore for the next 2/3 hours.

Answering to your question, yes im running on the original firmware...the only thing that i did was to just root my phone.
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
If your phone is only rebooting and booting normally - It may be premature to conclude that it's the emmc Failure - Normally when a phone is randomly rebooting it's usually related to the kernel - But since you are running the stock kernel - I'd be suspecting that an app may be causing the problem - Did you install any apps prior to the reboot issue?

Sent from my SM-G955W ??
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
Mhh, dont think so, i got on my phone just the most common apps (whatsapp, paypal, netflix, amazon, zappIR remote and some games such as clash royale/of clans). The strange thing is that yesterday the phone worked normally, without rebooting even once. This day it's already the second time it has been doing that. After rooting my phone, on the first interface, at left top corner, there is a message "Warranty bit: kernel", but i guess it's just Samsung Knox. Aren't there some app to "investigate"?
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
You could use Titanium to Freeze the downloaded apps and see if you get any reboots - If you don't - One by one unfreeze your downloaded apps until you get reboots again - That should tell you which one is the culprit ?

Sent from my SM-G955W ??
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
You mean Titanium backup?
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Yup - You said that your phone was Rooted right?

Sent from my SM-G955W ??
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
Yep.

So in order to make a sort of "summary", what we know is that my problem it seems to dont be correlated to emmc failure right, so Im gonna use Titanium and search for any possible app that can may be responsible for my phone's problem. If i dont find any "suspicios" app, should we have to consider the emmc failure hypothesis?
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
From what you've said so far it seems more like an issue with an app - As long as your phone Reboots normally (although inconvenient if you didn't initiate it) then I'd hold off on thinking that it's the emmc Failure - If your phone Reboots spontaneously into Download Mode - That's a strong indicator of the emmc Failure starting to appear ?

Sent from my SM-G955W ??
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
OK, so in the last few days i've been doing what you said about freezing apps with Titanium, but sadly, the problem persist. The strange thinghs is that differently from others people who are affected by emmc failure, my phone, while is rebooting, it has NEVER gone spontaneously in Download mode.
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
K - The only other thing that I can think of - Download the Latest Stock Firmware from sammobile.com to your computer - Download the Samsung USB Drivers to your computer - Download Odin 3.12.3 to your computer - Copy EVERYTHING you need or want to the external sd card - Factory Reset - Advanced in TWRP 3.1.1-0 - Manually Wipe System - Data and Caches - Power Off.

Boot DIRECTLY into Download Mode and Flash the Stock Firmware with Odin and Setup as New - Don't install ANY Apps other than a Launcher and Only Google Apps - Don't install anything else! See how your phone behaves over the next couple of days ?
