Having trouble diagnosing cause of lagging/freezing/rebooting issues. - Galaxy Note 4 Q&A, Help & Troubleshooting

I've had my Note 4 for over a year now, and just the other day it started becoming unusable. I had noticed some minor lags here and there, and apps would sometimes freeze and force close. I then decided to disable some built in apps like Facebook. The phone was running much faster for a couple of days, and then suddenly went to hell. It started lagging very badly, freezing up to the point I'd have to pull the battery. It will often randomly reboot, and occasionally boot loops a few times before successfully rebooting. I've tried everything I can think of so far, I enabled the apps I originally disabled, wiped the cache partition, did multiple factory resets, and today got a brand new battery. None of these things seem to work. It will run fine for a few minutes if it's been off a while, but then starts lagging pretty quickly. I also had pulled the SD card before, but didn't notice any difference there. However, I did just notice that it seems to run completely fine without the SIM card in it. I have my SIM in my old S4 right now, and I popped it back in the Note thinking the battery fixed it, but it started freezing up again. I powered down the phone, pulled the SIM card, and powered it back up. I've been loading all of my apps on the Note no problem now over wifi (no problems so far). The SIM and SD cards are in my S4 and that runs completely fine. Is it possible that the SIM is causing an issue in only the Note? I'm out of ideas at this point and hoping that someone has some suggestions. Thanks!

Full battery drain caused all core apps to fail, even after recharge...

Anyone have any idea what may have happened here?
I was unexpectedly away from home, but using the device quite heavily, and didn't have a method to charge the battery.
Once the battery had drained to about 3%, I switched the phone off but I ended up needing to make another call. The phone booted, but all core apps returned a force close message. Phone, Maps, Google Account, all the main stuff... Other apps would launch and function with no problem though.
Thinking it may have just been a glitch, I rebooted the phone again thinking there would still be just enough juice to allow a phone call, but while booting, the battery totally failed.
Once I had a chance to plug in the charger, all core apps continued to fail, even though the phone now had plenty of power.
Even after a battery pull, the same issues continued, rendering the phone pretty much useless. No link to Sprint, no WiFi network, nothing...
The phone is rooted with v1.5.2 RC and Fresh ROM v1.0, so lacking anything else to do, I performed a Nandroid restore from a backup made about 2 days ago and that seems to have fixed up the problem. (whew.. I did not want to resort to the RUU)
But, I just can't figure out what may have caused this odd behavior in the first place....
Are you using apps2sd?
No, I'm not using the apps2sd feature.
The lockscreen text showed "No service" and the notification bar icon showed the same. The "phone" application was the only one that would attempt to restart after being forced closed. After a second fc though, it would apparently give up.
Oh, and just remembered one other oddity.. Once booted and all force close messages removed, attempting to turn on the mobile network resulted in a hard reboot. I really didn't expect anything since there was no service link, but I was just clicking various shortcuts to see what did or didn't work.
Good part is that a Nandroid restore saved the day, so it's more of a curiosity at this point to what the root cause might have been.
I wouldn't have thought that a battery drain could have corrupted the apps or prevented the root filesystem from mounting.
You probably had too many apps installed. It's a known issue with the Hero, where having too many apps installed causes a bunch of core apps to fail to load for no apparent reason. The phone losing power just caused it to reboot, which triggers the issue.

oddly enough I've had a similar experience. it was 2 days before christmas and i was doing all my last minute shopping. heavy use of the phone caused the battery to die, so i just threw it on my car charger. it booted, but REFUSED to get any data at all (i didn't run into any fc's, however). I rebooted it 3 times and each time the issue persisted.
I was running the AOSP 2.0 build at the time, so i flashed my backup of 2.1 and everything was fine from there...

Hmm, good possibility there. Just did a count and I do have 85 apps installed.
(whoof, I had no idea the number had gotten that high. just too many useful apps for this phone.

HD2 w/ updated version of ROM freezing

I bought an HD2 last week that is already running the updated ROM (2.13.531.1) but the phone still freezes, turns off, then turns itself back on immediately. It does this several times a day. Is anyone else having this problem with the updated version? I love the phone, but it's getting really frustrating. I check the task manager frequently and close out of all programs that I'm not using. I don't really watch videos, listen to music or run multiple apps at once, and the phone goes through this freezing process during all different types of activities; there isn't any single app/activity that seems to trigger it. Also, I initially didn't realize that I had the updated version, so I waited a few days to install new apps (until I had time to update), thinking that I would have to re-install everything, and during that time the freezing did occur just as often, so I can't attribute it any app that I have installed. Once I realized that I already had the updated version, I installed a couple new apps.
Any advice on what could be causing this and what I might be able to do to fix it?
Any help is greatly appreciated.

I had this problem with my HD2 also even when I had did plenty of hard resets and installed custom ROMS problem was the processor was bad so I got a replacement for my defective HD2 now the one i have now runs perfect does not freeze at all and the battery life is perfect im now running MAY 31 Energy ROM
I just did a hard reset. I am going to avoid installing any news apps for a few days to see how the phone does. I' ll post a reply in a few days to give an update. Thanks for the help.
same here.
I have been having this same problem since i have upgraded to the latest version from tmobile website. What is worse it that, i am also having problems with playing videos on youtube. The video would start to play and after few seconds it will freeze and makes a very loud and annoying sound, then shuts itself off and restart, sometimes freezing while restarting, so i had to take out the battery. Sometimes it would freeze right after it restarted. It's becoming so frustrating dealing with these everyday. 40 percent of my time using the phone is spent on restarting, taking the battery off and waiting.
someone please help. thanks!
Have you done a hard reset since installing the new ROM. It's recommended by the super intelligent people on this site. I am not there yet, but I did a few hard resets on my phone after upgrading to the new ROM and it works great.
i would either
1 go back to rom 2.10
or, more likely since its so new
2 go get a new one, see if its the same.
I received a text message from t-mobile indicating that a new update rom was available for install. After updating I noticed that the mobile phone would freeze for a split second and then instantly restart. After having the unit freeze several times throughout the day, I performed a hard restart and did not install any cabs. I noticed that it would freeze when I would go online.
Just yesterday I downgraded back to the original rom and no more problems.
After the hard reset last night, my phone froze several times in the next couple of hours. It even turned off, then back on three times when I wasn't even using it and the battery was full. I have only had the phone for five days, so decided that is wasn't worth the headache and I called T-Mobile to exchange it for a new one. Hopefully, I have better luck with the new one.
Well, I received the new one yesterday and it's doing the same thing. Not sure what to do at this point. I'm irritated that HTC and T-Mobile released this phone when it obviously wasn't ready.
HD2 Freezing issue: Try this
For everyone who's having tons of freezing issues with their HD2. I found something interesting. I got my HD 2 a couple of months ago in June. It ran for almost a month, no freezing but sadly I had to return that one because the output resolution was bad. Some kind of defect. The second one I got for a replacement didn't have much freezing issues but I did encounter a couple and then I installed BeeJive. That program freezes my HD2 sometimes. Then I discovered that my WI-FI wasn't working, no idea what happened. I tried everything thing I could but it would not work. So I did a hard reset.
After the hard reset, the HD2 freezes all the time and was soooo slooooooow. It was so bad that I could not work on it. Having experienced the HD2 before all the freezing issues, I know that it had to be something else causing the freezing. So I hard reset again and reinstalled my applications again and tested each to make sure it was working and not causing the frequent freezing and most importantly, the slooooowness.
So far so good. I still installed BeeJive because it's the best IM software I found out there that uses your data plan for IM. It still causes freezing but I know what functions will cause it so I try to avoid it. I also keep my list of installed applications down to reduce the chance that it's one of my infrequently used apps that's causing the freezing.
So if you're daring, hard reset your HD2, then install your most used applications first, test it, then installed the next frequently used application next, and so on and so on.
One more thing, I've discovered that the auto update for stocks, weather, and frequently direct pushed emails, as well as gmail/yahoo accounts will cause the HD2 to be slow. I still set my gmail to update every 10 minutes because it's my main account, but yahoo gets updated once an hour and outlook gets manually updated during work hours, since I'm at work, and gets direct push for the hours I'm awake at home. No need to push email when I'm asleep.
Another possibility for resolution - microSD card
I purchased a new microSD because I noticed that the one that came with the HD2 is a Class 2 device. I could not take videos for more than a minute and then it gets real choppy.
I bought a new Class 6 card. After getting the card, I tested it against the Class 2 card. Huge difference. It seems that SD card speed and HD2 performance are directly related. I tested the cards with the following applications: Opera Mini, Opera Mobile, BeeJive, Camera, Video Camera, and Email. On both cards, on certain programs, the card access goes down to below 1mbs. However, for the Class 6 card, it ramps up quickly. The class 2 card, being already slow, lingers. This in itself causes a huge lag and freezing. I discovered that on certain applications that froze before, it now doesn't freeze but it does take an extra 'second' to recover.
My biggest relief has been that BeeJive no longer freezes where it froze before on certain functions. I've been running for over a week now without any freezes. I'm not saying you should replace your SD card, yet. However, you can test it to see if the lag is causing the freezing.
A new 16gb card costs $75. Make sure you test it, if you decide to get one. I got 7mbs max access with mine and consistently got 6mbs, which is what it's suppose to be.

[Q] Automatic Restarts Help

So I got my Note 4 (N910F) a couple of weeks ago, everything was fine until today when I changed the sim cards, now the phone randomly restarts. I have taken the micro SD card out, that seemed to increase the time between restarts slightly but it still happens, also checked to see if the battery was inserted properly but that was fine. Is there anything I can try before doing a factory reset? Would be a considerable chore to download/customise everything again with no guarantee of it fixing the problem.

same problem. but after factory reset. i haven't encounter any random restart
Just a bit of an update, found out that the problem was with the CPU power saving feature. Turning it off prevented the restarts from happening, just tried to enable it and got a restart. Would recommend anyone getting this to try disabling CPU power saving if they haven't already, before trying a factory reset.
Why CPU power waving causing restart when enabled?

Moto Z Force - Restart Loop

I'm having this issue on my 2 week old Moto Z Force.
I actually noticed a similar issue on a display model in Verizon but chalked it up to just that.. a display model in Verizon and I carried on with my purchase.
I've had a few experiences where it randomly reboots and then it's good to go again. Seems to happen more frequently when the phone is in high use, so I suspected an issue with RAM being full? The restart seems to take place at the same part of the startup animation every time.
TODAY - phone was in pocket while I was on a call for work and I felt it vibrate on a consistent interval. When off the phone, I looked at the phone and it is in a restart loop. The only thing I can do at this point is hold the Volume Down key to get into BIOs (through the rebooting loop) and then I have the following uptions:
1) Start
2) Restart Boot loader
3) Recovery Mode
4) Power Off
5) Factory Mode
6) Barcodes
7) BP Tools
8) QCOM
9) Bootloader Logs
If I sit in this menu inactive for awhile it will timeout and just shut the phone off until I turn it back on and then the loop resumes. I'm beginning to think I need to go with option 5 here... any help is appreciated...
No new apps were recently installed. I barely used my phone the morning when getting to work besides charging it to 90+/- % on my way in.
First I buy a hand grenade of a phone, forced to return, and now I buy a phone that is actually showing me a big issue (it is getting hot too). I'm going to let it sit off before trying a Factory Mode. :crying:

Thanks Steve. Any suggestion on where would be best? I would have thought the Q&A would be accurate...
I have had this phone for just over two month and have not had any similar issues. I assume that you've already tried options 1, 2, and and 4. Have you also gone into recovery to see if you can clear the cache?
I would personally return it as broken, but I save everything important to my SD, just in case this kind of thing happens.
I had this very same issue. I did a hardware replacement with Verizon and the new phone works great.

Awesome! Glad to hear that it worked out for you. Fingers crossed they don't give me a refurbished model (again, mine was 2 weeks old) and that I have the same luck as you.

I have tried all of the options at this point and none of those work. I can't even get into recovery. Every option does the same thing... reboots, reboots, reboots, etc.
New phone should be here tomorrow. I've got the good old run around on this one though and I'm not happy about it with Verizon and Best Buy. Best Buy's return policy is 14 days and I ran into issues on day 16, no exceptions according to them and off to Verizon I go where I had to purchase a temporary flip phone for the week my phone has been out of commission.
I'm in need of a new SD card before I put anything on there, it has been flaky. The only thing I care about on my phone is the media (photos, videos, and music), all of which are on Google. The crap thing is that now I need to spend another X hours putting all my apps, passwords, etc. on it to my liking. Just did this when moving to the Note 7, then Moto Z Force, and now again with the replacement. Starting to get annoyed.
Update - when switching to the replacement device I found the issue followed to the new phone... Meaning the issue was with the SD card or the SIM card. Found it was an issue with the SD card after switching between the two phones and experimenting. Unreal. Who would have thought?!
I will be formatting the card and keeping this thread posted on if that resolves it or if it's time for a new card (as I mentioned above).
I am very hopeful with your post. My phone has been going crazy with the rebooting mode for two days now. I brought it into Verizon yesterday but all of a sudden (of course) it started working. Now today its gone back to rebooting, over and over and over again. 2nd day in a row I am going to waste my lunch hour and run to Verizon. This time I will ask them about a new SIM card. BTW... I just got a new (refurbished) less then a week ago.

I just fixed my Moto Z Play by removing the SD card... for the second time... -_- I've had a previous issue where my phone rebooted as part of an update and it stopped seeing my previous SD card. After checking the SD card in various other systems, I found the SD card was completely shot. After some digging online, there is apparently an issue with the new Moto Z's that if your SD card isn't fast enough (somewhere around 85-90+ Mb/s)m, the Moto Z will slowly start to eat your SD card until it fails and causes issues for your phone. In this case, my second SD card failure was that my phone went into infinite booting loops until I removed the card. -_-
This card lasted longer, mainly I think due to the fact that it was larger and faster then my previous one, but it looks like I will need to get a new fast card.
Anyways, I hope this helps you or anyone else who comes across this thread.
About 2-3 weeks ago, the same thing started to happen to me, after that, phone started to act crazy...
-Bluetooth connection was working but glitching,
-Overheat (bottom of the phone) then started reboot in loop (until at start I'm able to turn off wifi). Did everything your supposed to do, clear cache, forget network, deleted my latest app, reboot, reboot in safe mode, remove sd/sim tray... the issues we're still there...
-After a few days of repeating all those steps (or don't know what I did), I finally got rid of the oveheat reboot loop when the wifi is on. But can only see and connect to 2,4g network, no 5g (doesn't see any) and no Bluetooth (turns on, but doesn't see anything), every other device in house works and connect like they should.
-the setting app, and the phone app started to be slow (freezes for a few seconds before the system ask you if you wanna wait or close the app, I choose wait and the app unfreeze)
-Ive tried the rsa (repair system assistant) from verizon without any fix
-finally decide to go for the factory reset. It fixed the freezing issues, works like a charm, but still no 5g wifi nor Bluetooth...
Is there a driver update possible for this ? Or because of overheat it might have damage the device...
I have the phone since September, never had any issues, went through all update, force droid edition xt1650-02, build ncl25.86-11.5, nougat 7.0 (wish verizon would update to 7.1.1 anytime soon), since its gsm unlocked, I'm using it on a Canadian network (Fido)
thanks for this thread. It was able to help me diagnose my wifes phone. The SD card she has been using since her DROID CHARGE (2011!!!) finally bit the dust in this phone. I swapped it out for a new Sandisk micro sdxc uhs-I up to 80 MB/s card class 10 and it booted. funny thing was she was not even storing pictures on the card.

I've had bootloops happen a couple of times for different triggers, and I still run the phone stock since release date with no updates ever taken. This has worked to correct the issue for me a couple of times. Give it a try:
Let your phone get down below 5% battery life, then plug into the turbo charger. Then fool around with whatever triggers the reboots.
Eventually the phone will not restart because the phone's battery needs to charge a little. When phone charges beyond 10% try to turn the phone back on, and see if boot loop persists. If it persists drain below the 5% battery life and try again. Usually, when I have fooled around with this scenario two or three times the bootloop has corrected itself.
Hope this works for you. Good luck.
Thanku, I will definitle give it a try .... and i am updated to nougat all updates till date installed...

A couple of weeks ago, the restart loop happened to me again, and my usual tinkering while connecting and disconnecting Turbo Charger wouldn't work. So I did some research on "stuck power button" or "power button not working".
I did the following:
I blew with my mouth over the power button (kind of like puting your lips in position to whistle)
I also gently tried to clasp the power button using a pair of tweezers, but couldn't. Instead I just kind of lifted/tugged-on the power button from the top and bottom.
I feel like I didn't really do anything, but the phone has been working for over a week now. Maybe pure luck.
Its weird, this made me think it is a hardware issue, but somehow the phone reacts as if it were software related.
Give it a try. Hope you have some luck.

My Axon 7 (2017U) became almost useless last night? Random reboots, lock ups, ect..

First off, I'm running stock-rooted, 7.1.1 - No Xposed installed. It's been running fine since the update came out (a few weeks).
Out of nowhere, my Axon 7 rebooted yesterday evening? It was sitting on a table, hadn't been dropped or anything.. After the reboot, it froze up and I had to reboot it.
Throughout the night, it rebooted a few times and I had to force re-start it even more. Then it wouldn't recognize my SD card on a few of the reboots (could my SD card be going bad)?
I'm having issues with my Playstore, other than "Waiting for Network" (yes, I'm having that too though). Downloads won't update, saying "try again later".
I tried a factory reset and didn't load any of my apps, same issues.
I'm getting ready to completely reformat my phone and start over.....Is anyone else having these issues, just out of no-where?
Mine spontaneously rebooted yesterday too. It then blasted the startup music even though that's turned off. It then had no data, as usual, and needed airplane mode cycled. My experience is that cell towers nearby matter. My phone works moderately well in some places but the radios crash every 30 seconds in others. Maybe you now have carrier aggregation in your area. T-Mobile 2+4 CA crashes mine constantly.
I wish I could believe that this would be fixed soon but I dropped out of the beta program because it seemed like ZTE just wanted a count of dead phones for each new build. I'd like to congratulate ZTE in joining Samsung, Panasonic, Lenovo, and Netgear as my list of manufacturers I'll never touch again. Making this list requires an exceptional dedication to releasing defective products and maintaining consistent customer deception about resolving problems.
Pretty sure it was a bad SD card.. Still had issues after complete rollback to Marshmallow.. Pulled the SD card out, working now.
