Locked screen waking up alone - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi there. I just bought a Note 4, 910F version, and i´ve been enjoying it a lot so far, but there´s something that it bothering me quite a bit. Everything was working flawlessly until a few hours ago when the phone starts turning the screen on, but stays in lockscreen mode, then the brightness goes to almost non viewable and stays that way. I try everything to make him go back to viewable brightness, but with no luck. If i unlock the phone sometimes the brightness comes back to normal and other times stays non viewable . . . . . . . . . . . and now comes the most weird thing of it all....the phone goes himself to task manager and starts force disabling/closing random apps. Sometimes only closes one, other times starts doing it to half a dozen ones and then all goes back to normal.
Anyone have any idea of whats causing this and why? Anyone experienced anything like this?
My phone is not rooted.
Thank you all for reading

Ok, so i figured out what is causing the waking, but now i would like to know how to make it stop. It seems that it´s the Greenify hibernating the apps that is causing the lockscreen to wake, but it´s strange because on my S3 that never happened. Any ideas of why it´s doing it this way in the Note 4?

serious problems with xda

over the past few days my exec has been getting worse and worse, originally the battery would run down really fast, ive read over previous posts about what people where saying about their battery problems but mine dsnt seem like most of them as the battery fully runs out before it turns off, it just does it much faster than it used to, and ive checked all my settings to help preserve the battery and none of them have changed, so i guess i just need a new battery.
next the screen turns off at random times and sometimes only works when the screen is facing one way.
i also have problems with the backlight sometimes it just turns off when i check the backlight settings, they have usually been reset, sometimes when i turn them back on the backlight comes back on and sometimes it just stays off.
it also experiences lots of lagging and often just freezes, when i soft reset the problems just continue.
recently i have also been having problems with the sound, the phone rings when someone phones but then i cant hear them and they cant hear me, also all of the other sounds that would usually come from the phone, dont.
i have hard re-set the phone, and all of the problems are still happening.
please can anyone give me any help, im not very technically minded when it comes to my phone so i may not understand all of your advise but i would be grateful for it anyway.
cheers.

Sense Keeps Crashing

im wondering if its just me..
most times, when the phone comes out of sleep, after i slide to unlock, it just hangs. i dont even get to see the clock, sometimes, it just shows a black screen, and sometimes, all i see is the lock screen..stuck.
i can push the start button, and it would work as normal, but i cant go home.. and everything else related to sense...music, settings, message, ..just crashes.
i always have to reboot phone to get it back to normal.
could there be something making it crash? ..and does it happen to anyone else?
yes it happens to me from time to time. sometime HD2 just lies on my desk and 'fall asleep'... cannot turn on the screen though all the buttons light up.
when this happens i have to call from my HD to turn HD2 on and when it's on, it's unstable, and i have to reboot it.
same problem
I have exactly the same problem. it just crashes for no reason. sometimes when WiFi is on. sometimes after I synchronize. sometimes if only plugged out of the charger.
it was in version 1.48 and kept happening even after I upgraded to 1.66
I hope this has a fix or something or atleast a way to restart sense because the Windows button works, phone works, except the volume, the turn off and the settings in the start menu..
help!
thank you in advance.
Same problem here. Freezes at the lock screen and the lights appear from the buttons. Occurring with worrying frequency now. Twice in the last three days. Any ideas?
folks, do report your issues here .. i have a feeling that this is a known hardware issue by HTC and they are just keeping veru quiet about this.

anoying white screen

Hi guys, this is my first post here and I hope someone can help me please!!
I got my phone 5 weeks no problem till last night,
basically when I am in screen lock state and then go unlock, I keep getting this anoying WHITE screen which coveres the whole screen and only on the top in narrow blue band it say "wiedges setting" to get out of this, I have to press the return button (on the right ) and it goes away , this happens everytime I go to lock position (after it stays in that position for 5 minutes or more),
Also I noticed even DURING my call after about 5-6 minutes through out the call this white screen appears and it ALWAYS goes away as soon as I press the return button.!!
so please tell me how to get ride of this?
if not, how to reset the phone without losing my apps and data? if I do factory reset is my apps will stay in andriod market, or do they also get deleted?
my phone IS NOT rooted phone.
what can I do, this is really killing me, as its everytimes into my face.
Please help me...
thanks so much
ps. is there any way that I can reset the phone to previously saved version! (3 days ago lets say),?
Sounds to me like an app causing this, as it seems it wants you to alter some settings.
Can you think of any apps you have installed since it started happening? It is usually always the fault of a dodgy app when you have issues.
I am not sure you can restore the phone back 3 days if you havent already done a backup.
Restoring your phone won't necessarily help as you will probably end up re installing the bad app once you are done.
I would try taking off some apps that you installed recently or anything you think might affect the screen.
Good luck and i'm sure someone else will be able to help
Biff.
edit: if it only started last night, is there anything you've installed just before it happened?

Screen goes black & everything disabled for 60seconds.

Once in a while my screen will go completely BLACK outta nowhere... NOTHING I do brings screen back on or does ANYTHING at all UNTIL about 30-60 seconds it suddenly comes back on..
**Here is the curious part.. When screen comes back it is ALWAYS in CAMERA mode! weird right? I'm thinking maybe a virus though have found none...
My ONLY other guess is that it may be related to app LASTPASS as im running it at time AND it has a screenlock function after idle timer...
The part with camera showing up on return is quite disturbing though, although maybe thats a result of me pressing every button possible during blackout??
Any clues or similar experiences? It used to occur daily.. Now just once a week.. Every virus spyware scan came clean.. Tho since phone is NOT rooted im skeptical how accurate these virus/trojan screeners can be without system access?
Phone has never been out of my possession & utilize screenlock since day 1...

It's an inherent issue with some displays present on the Moto G4. It most often happens when you charge your phone. Too much current builds into the frame of the display and you get weird ghost and jitter touches.
No way around it unless you send it in, and even then it may be only a temporary fix.
I also face this issue. Unable to find solid solution for this. Finally i decied to go for custom rom like RR and Invicta. This still comes occasionally(when Heats too much during phone charging)

On my phone this happens while not charging. Seems to happen about one out of every 3 times the phone is unlocked using the fingerprint sensor. Locking the screen and unlocking via a pin seems to be a reliable way of getting past the issue. Though occasionally it happens on the pin entry screen before it the pin has been entered. Needless to say, it IS annoying.
Same problem which is fixed.
I had this problem with the factory firmware too, intermittent bouts of the phone going crazy with phantom touches on my Moto G4. I sent it to Motorola/Lenovo after the supplier gave me their phone number and they did find the problem and fix it. Now I can play graphic intensive games even during fast charge and the phone is awesome for once. : )
Please note they will fix it for free if in warranty and bootloader not yet modified.
Pressing power button to turn off the display and then pressing power button again to turn the display back on will provide temporary relief from jittery screen. I noticed that the jittery screen has twice subsided over time but came back twice immediately after OS upgrade so blaming the problem on charging, or hardware doesn't seem accurate.
Updated 5/20/2018
As a last ditch effort prior to buying a replacement phone I deleted all apps I installed, reset phone and reinstalled fresh copies of most if the apps I needed.
I don't recall every thing I did but my focus was to delete everything I could and then reset phone back to factory state. After reinstalling, my jittery problem went away and has not returned. Your millage may very, so no promises. Phil

phone going crazy
Hi,
I am having the same exact problem. I have observed that Google Assistant is intruding because each time this happens, Google Assistant is trying to run. Reboot is a temporary fix but the problem persists. I have removed most of the third party apps just to see if anything changes but it did not work.
This is not something that was happening from the start. I have the phone for about 2 months put the problem only started a couple weeks ago. I would love to hear if there is a solution and what. Thanks
Sadly, but compared to the issues visible indoors, in outdoors this Lenovo gift turns complete crap:
youtu.be/dTcHclVEfCg
"Lenovo Moto Z2 Force touchscreen gets completely unusable when getting outdoors! The video is made at about 0 degrees Celsius. So it takes about 30 sec from getting MotoZ2 Frc to sleep with pwr btn (and wakeing up back) to see the touchscreen goes crazy. At -10C, it takes ~5 sec. At +15-20C, after several min it becomes unresponsive and have to use pwr button to recover.
Lenovo, what you have done to Motorola ?!!"
Can it be fixed somehow with changing the upper protective part? I have seen comments that the touchscreen can stop working completely, if peel off the cover part..
