[Q] My Device All Of A Sudden Is VERY Buggy - Galaxy Note 4 Q&A, Help & Troubleshooting

I have a Sprint Galaxy Note 4, it's rooted but that it.. NO custom ROM or custom, anything really. Just a Galaxy Note 4 that has root access!
I've had my device for a total for maybe.. 5 months, and it's been rooted since last week.
Since yesterday, all of a sudden my phone is extremely buggy. All of these errors and problems have NEVER occurred before, and now they occur extremely frequently.:
-Scrolling through Gallery app is super jerky, it's like my phone things I'm trying to scroll up and down with 4 fingers on the screen at once. (This has never happened until yesterday)
-Messaging app takes sometimes 6 secconds to load up. (This has never happened until yesterday)
-Phone will sometimes make it to 0% then die, or sometimes die completely when at 15-20%. (This has never happened until yesterday)
-Nova Launcher crashes maybe 4 times a day on average (This has never happened until yesterday)
By "Yesterday" I mean.. probably yesterday, but possibly just the last several days in general. I literally didn't do anything to my phone that would've caused this, other than simply rooting it. I just rooted it, no custom ROM or custom anything else..
Anyone know why this may be happening, or any fixes? Thanks!

back everything up. flash stock ROM through Odin or Kies then restore.
Before that try enter *#2663# into the dialer and then click TSP FW Update

strange issues with my Vibrant

running rooted stock Vibrant. Phone was doing great until yesterday.
All of a sudden It started going into a reboot loop. Did a factory reset. waited for about an hr.
Then started installing my apps. I only use a bunch of games, launcher pro and some others, nothing crazy. after about 3 hrs of playing word wise, it starts it again. This time I notice that the notification bar it takes a long time to run the media scanner. sometimes it scanned twice , then reboot over and over. I finally did a factory reset again.
Could it be Launcher pro? I havent reloaded any apps at this time, and it been 10 hrs with no reboot?
Anyone else had this sort of issues?
I've used LP since day 1 with absolutely no issues. I would have to venture a bad app?
I think it might be beautiful widgets, or fancy widgets. I think it went into a boot loop when it did a auto time and date update. I kept seeing that at the bottom of my phone before it rebooted.
dunno, will be very frustrated if I cant customize it the way I want.
Well, I've used BW from day 1 also, no issues.

didnt figure it was one of those,
guess I will have to look at one app at a time.
Sorry man, if discovered, will you let me know via a PM so I can put it in the sticky as a possible problem?
are you using setcpu? i was having all sorts of problems with phone hanging and never waking and such with setcpu...i finally just did a nandroid restore and uninstalled...no issues since
not using set cpu. very wierd. hasnt happened since my last factory reset last night. installed apps, not all of them because I am in the process of seeing if I have a bad app.
just taking it slow to see if I can duplicate the problems.
only thing now is that I have a problem with disappearing icons on my launcher pro dock LOL

Random restarts

The past week I got 3 restarts on my note. First was at home with USB cable to PC to charge it, nothing else, locked screen, don't remember if there was a running app. The other 2 times where on the road, I was listening music on stock music player. The only app I am thinking it could have something to do with this is top deals, even not 100% sure need to confirm got rid of it now let me check it. Anyone else noticed anything similar???

It happened to me few days back. It did not restart but I found it was off. Battery was around 50% and it was on third day after restart. I think it could be remote desktop app called 2X - Note particularly gets slow after runing 2X couple of times. I am on 2nd day without running 2X and I wish to confirm if this app is playing something wrong (btw I didn't have problem with 2X on S2).
Yup. It does happen to many people. "Sleep of death" happened to me several times on stock speeds/voltages. Restarts on my phone seem to be more OC/UV related.
I got mine about a week now and have had several restarts. It was way worse before I ran the update though... Now it "only" reboots 0-3 times a day
I don't dare to root it before I know it software related, but it seems like that since it got better with the official update...
I have restored it to factory defaults etc and nothing helps. I experienced this with NO extra apps installed and with the 4 apps I installed it's not worse. (Don't wanna personalize it before I root OR send it back and hope for replacement.)
Third day and it restarted. It however did not reset System Uptime.

Never had a random restart or sleep of death, in fact I can only recall 1 FC and I've had the phone for 2 weeks now

Lucky you!
Well what I wonder is if I root it is it possible that a custom ROM will fix my problems?

Note 4 (T-Mobile) Lag, Freeze, Crashes, Restarts.

This is my first post on this forum. I searched around here for a solution, didn't really find one matching my problem. I am not a phone wizard or anything like that either. So I'll try my best explaining my problem.
First things first:
Phone: Note 4
Model #: SM-N910T
Android Version: 5.1.1
Rom: Stock Rom
Rooted: Rooted Once and used a custom Stock T Mobile Rom Once.
Here's the ROM I used at the time: http://forum.xda-developers.com/not...10tuvu1cog2-debloated-deodexed-stock-t3175406
Recently I So recently my phone out of the blue started lagging, freezing, and restarting itself. I didn't download any applications or anything like that for it to freeze up. I was currently then on the custom ROM I have mentioned above and it was the updated version. I have tried everything to my knowledge to try and fix the problem. I have tried going back to stock T mobile ROM (currently on stock rom now) through odin and stuff. After all that, it was still lagging, freezing, and restarting etc... Ran it through safe mode and the only problem in safe mode is that the lag is gone, but the restart is still there. Running in safe mode, if I would turn the screen off and back on to unlock my phone, there would be like 40% chance that it would restart after unlocking the phone and the phone would just restart normally. Rarely, whenever my phone would attempt to restart.. I would get a "Could not boot normally" message along with couples codes below and the image of android guy. Then I would have to take my battery out and attempt to restart the phone once again.. I've wiped the cache and everything in recovery mode, nothing helps at all. Also, the phone is in perfect condition. Hasn't been dropped, cracked, no water damage, or anything like that.
This place is my only hope to fix my phone before I will go out to buy another phone from the carrier.
Thank you all for taking your time to help me

Well I already got rid of my note 4 unfortunately before anyone could help me here so I had to upgrade my phone to note 5 and return note 4. While I still had my note 4, I realized something weird. While the phone was lagging and crashing etc.. When I had it plugged in for charge it would work perfectly fine. No lag, it wouldn't freeze up or restart (had it running perfect for 7 hours). It was like my phone was brand new again. As soon as I unplugged it from the charger, few minutes in and it was back to restarting and all that. I never knew why it did that.
Anyone know why this mightve happened?
Might be the battery though
I thought that too. I tried my brothers note 4 battery for awhile and it worked for a little bit and then it started doing the same thing even on his battery. Shrugs.

In the COH update iteration there is an annoying bug that affect fingerprint.
The bug causing the phone to restart, lagging & closing all apps randomly when the fingerprint is set.
May be this one is also the same.
Try to disable all fingerprint related settings.

I never used finger print scanning on my Note 4. Always disabled.

Note4 boots into download mode.

So, here is my problem. I've got an almost four years old Note4. I flashed some custom ROM's after i bought it but then I found an old X-note 4.4.4 based custom ROM and i was using that for more than 2 years. Yesterday around noon i noticed that if I try to use Viber, it takes seconds till it opens, and lags badly. (Before that the phone was working perfectly for years). I deleted it, reinstalled, but the problem stayed the same. After a few hours all the other apps started to do the same, the phone became really laggy. As time went by it got worse and worse, around 8pm it started to freeze, reboot, became almost completely useless. I thought maybe a factory reset and a new flash would help. I did a factory reset, and flashed a completely stock ROM on it. It started well, was working good for an hour or so, and then the same problems occured again. Lag, freeze, reboot.... And then nothing. Did not even restart. I can switch it on every now and then, (like in every 20 minutes), but it boots into odin mode. I thought maybe the battery, but that is less then 2 months old. Anyone any idea what happened? I mean the phone is almost 4 years old, so I'm not really pissed off, the only reason why I wanna keep using the Note4 cuz it's removable battery. I don't like phones with built-in battery, this is why i did not upgrade to Note8 for instance. Any help would be much appreciated. By the way, my device is an SM-N910F.
Well, things got even weirder later. I found my old battery which i replaced 2 months ago, still had some juice in it, i put it in, and the phone started!!! Worked perfectly, for about an hour and a bit, then the same problems occured again, lag freeze reboot, and now it boots itself into recovery if i can start it up at all... All the same story. Anyway, i threw it in the drawer and bought a new phone.

Weird System Bugs/ Issues Stock

Hi, I have owned a One Plus 6T for a few years now, didn't have many issues, until the last few months. I used to be on Android 10. (something) can't remember and the issues I'm about to describe happened on that version too. I have recently updated to Android 11.1.1.1 and the problems still persisted. And I've run a factory reset a few days ago and that still hasn't solved the issues. My bootloader is unlocked and I am not rooted.
Issues:
1. Phone randomly rebooting (almost like there isn't any RAM but there's over a gig spare) eg Ill be listening to spotify and suddenly phone reboots
2. Extreme System UI delay/lag and screen lag. This is the weird one. Happens at completely random times. Phone will slow down extremely to the point where nothing will be responding. For example if I click the power button to look at the lock screen the screen will just stay black for ages. Apps will not open etc. Can barely even swipe or do anything, it happens multiple times a day too.
I was wondering if anybody knew why this might be occurring, considering I am running a fresh install, unless it comes down to just bad software.
