Safety feature when using camera? - Galaxy Note 4 Q&A, Help & Troubleshooting

When video recording for over 20secs, the screen will go dim and when u go into brightness settings i will get a message saying the device is overheating if you try to change the brightness back to full, this normal?
It happens on both 5.0.1 and 4.4.4..
I checked the temp straight after and it was only at 40c.. I have literally just bought the phone and never experienced screen dimming on the note 3, possible bug, faulty phone?

Not experiencing that on both version even when recording 4K. Maybe you're encountering the issue below.

Yes i do notice the top half of the phone getting really hot, but ive only had the phone since saturday and dont want to root the phone just incase i have to take it back, any other options?
EDIT: Got the phone replaced, using the samsung stock camera the screen will dim a tiny bit and in the brightness settings it will say device is overheating even though phone not warm must be a safety feature to stop phone from overheating itself, downloaded snap camera and there was no screen dimming or warnings in settings. Checked my old note 3 and the same thing is there with the dimming and warning.
I read somewhere about knox being a culprit so i will look into that due to all the security features etc.

HTC One 4.2.2 update pros and cons

I updated my ONE to 4.2.2 around 3 days ago. Needless to say its a pretty cool and major update. Still some observations..
Mentioned in Update Changelog
DayDream
Improved menu button
Notification Bar
Quick settings
AE|AF lock
Back buton = start of Blinkfeed
Some of the good stuff which wasnt mentioned in the log
Gallery has removed the extra step to go to events,albums etc
App drawer animation is waaay smoother
Dynamic contrast now doesnt flicker the screen [I think]
If you have multiple types of numbers stored for a contact, it comes up in small just above the message from the type the message has come
Some of the Issues I found
Normal mode in camera produces a blue tinge in the view finder
BoomSound volume is a little lesser
Power saving mode has degraded. Or maybe the brightness level has been increased. Something has changed in that
One more - I got Wechat preinstalled after this update!
Any of you facing any issues?
I saw nothing wrong with the camera.
But i hav one priblem since 4.1.2 the keyboard flicker sometime, does anybody hav this also??

Can someone who has 4.2.2 comment as to whether there is still a waiting period when sending group messages? What I mean is that when you send a group mms message, there is a small popup with a blue circle that says "Please wait..." Is that still the case? Thanks.
I can confirm too that boomsound sounds a little lesser. and the camera I tested In a bright sunny day, in the screen is something (better I think) and them the picture taken is a little warmer.
The sky quality even in sunny day have a very bad quality. its like 8bit blue color.
my sound isnt as loud anymore and i think my battery got worse, i get 1 hour less screen time -_-
Sound is down for sure but my guess is that some people blew their speakers with very loud files I assume this is a "fix"
Power saver mode doesn't work after update.... Seriously need to fix it soon

cons:
- proximity issue
- crackling noise during call

Yeah proximity issue. Once a call starts, suddenly the screen would go black and I have to toggle the power button to turn it on. And when you do that, it wont turn off i.e the proximity wont work.
I have no issues with the camera, seems very good still to me...I get the proximity issue though it seems intermittent, I don't really use the speakers to be fair so not sure about the difference there. They still kick the crap out of any other phone I've heard so can't complain! I also think my battery isn't as good as it was though I'm getting there with it. Think the settings are just a little different. I did notice that there seem to be two auto-brightness settings by default if you tap the brightness in quick settings there is a bright and a dim auto-brightness by the looks of it to me.....might be wrong (and I dont mean powersaver auto-brightness, that is lower again!)
Since the 4.2.2 update, my wifi takes between 2-4 attempts before it successfully connects to my d-link router, i also have an Huawei router and it`s the same, before the update it only took one attempt
Also the new drop down setting list, wifi, bluetooth ect. where is the GPS one.
John.
Videos didnt work after update
I have videos downloaded in my videos folder wich were running fine before ota 4.2.2 update. but after update video extension were not supported anymore.
i am running htc stock videoplayer only
Battery... battery took a hit, and not a small one.
I'd say 20% is just gone... and "Kernel (Android OS)" looks to be the bad guy who's ****ing things up.
battery life has gone down
Worth noting that I had massive wakelocks from 7 Digital so disabled that and my battery seems better already.....

Mine went down for the first couple of days but now seems to have settled down and if anything is slightly better.
Seems the battery needs to recalibrate over a few charge cycles.
15% and 100% battery level notification sound, wish i could disable it

Anyone?
Also i think it takes more time to charge now..
As people mentioned, battery might need 3-4 cycles to recalibrate...
And yes dynamic contrast flickering has stopped. Screen doesn't into an infinite loop trying to adjust the brightness on a white background screen. Need more confirmation though..

Battery is horrible, I got my update about a week ago and no improvements. In fact, after first charge since 4.2.2 battery was EXCELLENT. But since then, it's awful. Power saving mode is not working, I had it on all the time because phone would overheat in these temperatures. (40+ degrees).
I am seriously thinking about rooting my phone and installing Paranoid Android on it, I love Sense but 4.2.2 just made the phone worse in my opinion
The only thing that's keeping me from moving it's the boom sound + beats audio.

[Q] some strange adaptive brightness randomly

helllo
Even if I am using manual brightness set to max - when browsing for example XDA forums which has alot of white - I notice if i drop down the statusbar to check notifications - then go back into xda the screen dims down a notch. (Going from alot of black to alot of white)
This is with all auto-options set to disabled and at max brightness.
This also occured in omega rom, also MF8 base.
And sometimes after a while, it can go back to max brightness randomly. I feel its some sort of adaptive brightness thingy that is misbehaving - even though everything is set to manual.
I tried MGA but its the same thing - . -
and it happens randomly. then after a little while the brightness can go up to max again.......
There's an option in the display settings which is badly named but which turns off this behavior. I think it's named adaptative display or auto tone or something like that. It's the 2nd from the bottom.

Same problem here. Couldn't find any 3rd party app to address this. Tried almost all brightness related titles in the play store. Hope someone will come out with some dolution for this. It's sooooo annoying!

Same probleme here....
That made now 2 weeks that I search a solution. All the options of auto-luminosity are disabled, luminosity set to the maximum manually, auto-tons disabled and eco mode off but despite everything, in a dark part, my screen dimmed. It is very disturbing because it dimmed then return in full luminosity etc.... It is a problem but beyond that, I noted that at the time when the automatic adjustment of luminosity occurs, the processor also loses in frequency. It still reaches a maximum at 1.458 ghz or worse at 1.2 ghz.. I tested several Roms: Stock rooted, Google edition 4.3, V8.0 Omega, the result is the same one. I tested several Kernels: Faux123, KT-SGS4 and Adam Kernel. I tried to block the processor at 1.89 GHZ (min + max) at a session of games but at the end of a few seconds, automatic reduction of the luminosity and decreased processor. I think it is not a hardware problem because much of users of Galaxy S4 have this worries.
I become insane with that! And my wife also
Is it possible that a developer integrates a corrective in next a Rom or perhaps make a tweak?
Sent from my GT-I9505 using xda app-developers app
I think i know what's causing the issue.
When I got my phone I noticed the same thing. Apparently its a function of the software deep in the system(at least that's how I understand it). There is no easy way to turn it off. Basically it throttles the screen brightness depending on the average amount of white displayed. The more white the more the brightness is throttled. Not sure if it's to prevent the screen from overheating or to save battery or for both. It's kind of like how the screen can ramp up to a higher brightness when in auto than when in manual. I think it's a thermal issue, but not sure.

i also think its thermal/power saving related.
a kernel tweak should fix it.

Screen flashing

Hello xda, I don't know if it is problem or it is that "technology" when i set full brightness, I notice that screen is somehow "flashing" anyone facing that or it's just me...
I noticed this flickering, but not always, just in two live wallpapers, I think it has to do with the number of fps, some lwp use different fps, from 20 to 60, as I have not noticed this in the rest of the apps, native or installed, I think these two apps cause this, not the hardware

I went to Samsung store and every Note4 has screen flickering, when you are not watching screen for example you are looking at home button you'll see that screen flickers.
You are sensitive to flickering and Samsung use this technology for better battery. There is nothing you can do except get used to it or get another phone without amoled.
It funny how all pc monitor market move to non pwm flicker free as selling point, and yet Samsung use more and more aggressive flickering.

Screen flickering on my OP2

Out of nowhere, my phone's screen has tarted to flicker. The brightness flickers and is very distracting. I've already tried to flash the latest OxygenOS available, but it hasn't worked.
Thing is, it flickers in both OOS and TWRP but it doesn't when booting up and in the bootloader.
Is it a hardware issue or there's a software fix?

Nope, in the end I had to RMA the phone.
I had to go through the hops from support, but they were certain it was a hardware fault, I had it fixed at no cost.
There can be two things, one's Adaptive Brightness which usually does that, check if you have it enabled, disable it.
Second thing can be CABC (Content Adaptive Backlight Control) which works as opt's lcd throttler. It throttles, i.e. puts the brightness to a bare minimum when the temperature of the screen exceeds a particular value.
Now disabling this isn't very productive and/or practical. But if you want it disabled you can flash cm13 (a custom rom). On cm13 I've realised it works only on temperatures more than 65-70*.
I suggest you to keep your opt cool as long as you can.
Mine started flickering just after I made a change in Settings, and it was Turning OFF Adaptive Brightness
Mine just started flickering after I didn't change anything at all. Never used adaptive brightness in my life.

Always On Display bug/issue after latest Firmware update 09.April.16?

Hey, i updated to the latest firmware that came out today 9. april 2016. Firmware version : G935FXXU1APD1/G935FNEE1APC5/G935FXXU1APD1. My Phone is a Nordic Edition S7E with Carrier Telenor Norway.
after the update everything works like it should except the Always on Display. The AoD works but its always on the lowest brightness... it moves around, shows what i ask etc but it wont get brighter when i go outside or shine something at it, auto brightness works fine on the screen when its on. my question is: does this happen to anyone else? this has to be a software bug within the AoS app or the OS itself :/ cheers
What version does it show in the AOD settings ( About AOD)
Version 1.1.14
I guess its a change, this is the version i have. Im on fw PB6
it seems like it does work tho much slower than before, i think they tweaked the sensitivity on the brightness, because before it changed waaaaaay to easy, now it stays on the right brightness for the area you are in, tho if you go from a dark room to a bright room it takes waaaaaaaaay to long for it to change, and when you take it out of you're pocket it will still be on the lowest brightness for some reason... so AoD is now useless outdoors if its sunny out, ill guess they will change it again since i think they over did it.
it is not a problem it is intended to reduce power uage.

iknow that, but the point of AoD is that you should not need to turn ON your display, now you have to if you are outside, since the update rate it so low on the brightness. for indoor use its awesome tho.

Idk about the brightness, mine bases itself off of lighting around me. As for it moving, that is to save your screen from AMOLED burn in.
I have a real problem with AOD, after the latest T-Mobile April security update, AOD doesn't move and it should to prevent burn in. I currently have it turned off until it's fixed.

i know it has to move the issue is that it takes so long for the brightness to increase/decrease after the update when the light changes in the room/place you are, so when you are outside and take your phone out its on the lowest brightness, so you cant see anything, it takes over 20 sec before it increases the brightness. but why there is so many " latest version" of the AoD is weird if you ask me. it worked before the firmware update tho it increased the brightness to the max much easier before, so it used a lot of battery, i think they tried to fix this but overdid it. that is why i'm asking if its happening to anyone else.

Oh, sorry I misread that. I thought you were having multiple issues. Yes, mine takes forever too.
I don't know why they just don't put it in the Galaxy App Store so that all can have the latest version.

Yeah they really should put it in the app store, just like they did with the edge features, but i didnt receive the new updates yet, so im waiting for it
i did a test now, it only changes brightness when the AoD moves for me, i guess that is how it should work, i don't remember how often i did back on the PB4 firmware but it was much more sensitive that is for sure.
latest firmware did break AOD for me too, T-Mobile US. AOD no longer moves. Not sure if I noticed before but waking the screen up now with power or home button, the screen fades in somewhat. It's a very quick fade in but noticeable because it's not instant.
I am seeing some serious problems with the AOD- I even asked for an exchange thinking something was defective. I got my new phone today and it reacts in the exact same way: AOD brightness changes completely at random ie I am not able to see any sort of correlation between how dark/light it is where I am. AOD version is 1.1.06, while the firmware version is PB9.
The other issue I am seeing is with GPS- worst that I have seen until now. I tried it with GMaps and a couple similar apps- the arrow that shows the direction does not move around based on which way the phone is pointing. This was the exact same on the phone that I sent back in exchange for the new one this morning..
