Freezing and Restarts! - Note 7 Questions & Answers

Got my N930FD from Dubai two days ago and had freezing and rebooting issues after a couple of hours of playing with it.
Got 2 OTA updates but no luck, changed FW no luck either.
I guess i know what the problem is - it's the fingerprint scanner!
I disabled the fb lock and kept iris and the freezes disappeared, once i re-enabled the fb lock it went back to freezing.
Going tomorrow to Samsung to drop it off, hopefully they'll change it for me.

Strange slowdown and freeze

Hey all got my gn gsm from mobicity au about two weeks and today I had something strange happen.
I was at work got a SMS the phone started to make a tone but very slowly and it repeated it ( which is strange) then I put in my pin and unlocked my phone to find that its lagging like crazy, home screens are sticking and freezing . So I reboot, once rebooted the phone tells me that the ics launcher has stopped working, and its still lagging can't open settings.
So once again I restart and take out battery this time all is well, battery went down 10% at that tine also.
I'm on 4.0.1 Google build all stock.
Any one else have this issue?

Very strange issues with my M8

I've been using unlocked international M8 for more than 5 months, and I've never had any problems.
Few days ago I updated it to 4.4.4, and everything worked perfectly. But today I've noticed some strange issuses.
1. Screen turns on by itself
2. Auto-rotation is off, but screen is still rotating in every angle (including 180). I can even rotate screen on lockscreen, home screen or app list.
3. I can't browse the web because pages are constantly refreshing them by themselfes.
Phone is fully stock, never rooted.
Anyone has similar problem? Or does anyone know why is this happening and how to solve it? Any help is appreciated.
Random bugs after an update can often be resolved by backing up your personal data and doing a factory reset.

Random Rebooting

I haven't unlocked the boot loader nor added any custom ROM on my Pixel, but last few months it started to reboot at random times. I did a factory reset and it lasted a few weeks before doing it again. I've been slow to add my old apps back to see if it was an app, but it doesn't seem to be the case.
I thought about flashing a ROM, maybe it would help haha.
Any ideas?

Do you have Pokemon Go installed? I have the same problem when that game is installed.
I don't. I don't have any games installed right now to test things but it still reboots.
Having the same problem - started about 2 weeks ago as far as I can tell. Haven't done anything to the bootloader and isn't rooted - completely stock. Seems to happen when browsing web pages, or pages with links on such as within Twitter or Google app. Not every time. Phone just freezes for about 3 seconds and then reboots. WTF?
I believe this is an app problem so try to pay attention to what specifically you are doing when it happens. Like the guy above says, happens fairly frequently with Pokemon GO since one of their updates this year-ish. I personally haven't noticed it anywhere else.
Have tried uninstalling bitdefender ... see if that makes a difference
2 DAYS LATER - seems to have solved the problem!

Camera cannot be started

After about 1,5 weeks of usage, the camera cannot be started anymore since a few hours.
Rebooted a few times already. There is a popup stating that the "camera could not be started, either reboot or restart the camera".
It worked a few hours ago and since then nothing happened with the phone.
I cleared the cache of the "camera" app and made a fresh start. Other camera apps also do not work.
What happened? :/
EDIT: I did a factory reset and the camera is working again...
Just out of curiosity what build were you on when this happened. I only noticed the problem after I updated to the latest update version ending in .225.
The only way I was able to fix it was by powering off the phone and then powering it back on because clearing the cache/restarting it didn't work. It worked fine for a while after the first power off but then it started giving me the same error after a few hours. So now I powered off a second time and it's been about 12 hours since and so far no issues....
Next time, take a bug report from developer settings, and post it in their official forum.
Had the same problem twice in the first week of the phone, looks like hang after U use the super slowmo and dont close the app. at least was both times after using the slowmo and just locking the phone
Just started getting this error in the last few days. Most of the time a reboot fixes the issue. Sometimes it takes several reboots. BTW, I did the most recent software update a couple weeks ago.
Had the same issue, it also causes a battery drain.
The app BetterBatteryStats showed a 100% kernel wakelocks of the process "Sony,camera_modules".
My battery drained from 100 to 40% in 4 hours with just 10 minute screentime.
I've expierenced camera cannot be started error now 8 times, rebooting temporary solves the problem...
Hopefully a OTA update will solve this problem.
Hi, i have the same problem with latest .225 built
Camera works but black screen, and after 3 or 4 times crashed.
The only fix is wait an update by sony??
Me too. Same problem. I had to Factory reset. It pissed me off....
Now sometimes it appears but i reboot and then goes back .
I confirm i have the same problem with the latest firmware but i have it one time with an old one to. For me it's happens when i close the camera app while i have the phone on horizontal. Some time to recover i just open the camera with the phone horizontally but sometimes i need to clear data and restart the phone to make it work again XD
Maybe the wrong thread, but is there a way to take motion photos (like in gcam) on the XZ2 Compact?

Random Freezing and Crashing

Hey guys, i love my pixel 3 XL its been great but it has been randomly freezing and locking up, somtimes requiring a restart.
Other time i get the system UI crashed message and then i close it and it works again. Sometimes Chrome or the camera app locks up and crashes too.
Anybody experiencing this? Any ideas on a fix, maybe the next December OTA will fix it hopefully.
Thanks

I'm getting pretty fed up of factory resetting my phone, the phone started saying it's corrupt so I ended up reflashing it and that issue is now gone, but this freezing issue happens every now and then. You really think a factory reset is worth trying? Or could have something of gone wrong with the reflash?

I absolutely would try a factory reset if things are acting strange for no apparent reason.

If you flashed the factory image it's either a hardware or app issue. Have you tried using the phone for awhile with a minimum of apps? I'd give that a try I don't think a factory reset will do anything if you've already flashed the factory image.

try the flash-all.bat then when its complete go to stock recovery and format /data
are you using substratum?
Pixel 3 XL crashing
I have had the same problem. My system UI crashes since new, along with other apps and the phone becomes non-responsive. I thought it was just a new phone glitch that would be fixed with an update, no such luck... I need to do a hard reboot by holding the power button until it reboots. I bought a Pixel 2 XL in August and never had any problems like this. I finally contacted Google about the problems and they RMA'd it. I never root my phones before making sure they work correctly, so this one is and has been stock, unrooted.
My wife and I have the 64GB models in Black (mine), White (hers). She's on her 3rd replacement phone for what seems to be a similar issue.
Symptoms:
When using the fingerprint reader to unlock the phone, it may not unlock for 10+ tries.
The phone's battery drains quickly, within a couple hours of barely any use, her phone might be down to 60-70%
System_UI crashes
Some apps don't seem to load quickly (Like going into messages, you see the app container, and a new chat button, but no messages load for a minute). Or she's had a straight up black screen, and the app wouldn't load.
Takes minutes to call or hang up a call and often takes rebooting to close out the phone app.
It almost seems like something is running in the background that is utilizing the CPU and causing the lag/app/battery issues.
Troubleshooting:
Factory Reset
Wiping Dalvik Cache
Replacing the phone twice through Verizon. The first replacement had the same issues immediately. The 2nd phone showed the same issues immediately, and then went away for 3 weeks since the Dec. 5th Security update, but in the past few days has returned.
Booted in Safe Mode (everything seems to be working fine however extremely limited).
We've also checked the processes and no apps seem to be running that would make any sort of impact.

Since the December update, the freezing issues I was having have been significantly reduced, but it still freezes sometimes... I am hoping the January update coming in the next week will smooth out any remaining bugs.
Any of you using a different launcher?
I had this freezing and non-responsive issue. The google rep, replaced it, he determined it is some kind of hardware issue. My replacement didn't have this issue at all (November update). However, the lag/stuttering still persists though. I had replaced quiet a few pixel 3 XL, and i am just getting tired of it. For a $1K phone, we shouldn't get mediocre quality of phone.
So my wife had been removing applications in small groups to try to narrow it down. It seemed for a week or so that she was in the clear and everything was working. Then all of a sudden she got the January update and her phone is still having issues.
Slow responding finger print reader.
System UI crashes
Unable to answer phone calls despite numerous attempts.
It still seems like there is something that is running in the background that is just using the processing power.

Get gsam from the app store, if you don't have it. After awhile see what apps are using battery, app sucker in the app. Gsam is a battery monitor.

Sadly, gsam and accubattery don't show anything out of the norm app wise.
