Galaxy Note 4 heating [camera]

I purchased Galaxy Note 4 [SM-N910G] a week back. It's on Android 4.4.4 (KitKat)

I am having a different problem for which I could not find any satisfying solution on the Internet. Whenever I open camera app, the phone starts heating up near camera & battery also drains very quickly [around 2% under 5 min.]

I know that the phone will heat up a little bit when playing high graphics games, but I don't think it should heat up too much when using camera app.

I have already factory reset [both soft & hard reset] the phone, but still it does not help. I contacted Samsung support, & they told me to 'Reset app preferences' from Application manger, but still the device heats up when using camera app.

I also cleared data of the camera app, but still the issue remains :(

The phone does not heat up at all on standby mode, but opening camera app raises it's temperature more than it should. Previously a Note 2 user, this problem was not there.

Anyone else experiencing the same issue on Note 4 ? Any ideas on this ?
[Galaxy Note 4 Q&A, Help & Troubleshooting] RISHI RAJ:
The phone heats up only if you're recording 4k or 2k video.If you use camera generally & your device heats up.You must get your device checked
[Galaxy Note 4 Q&A, Help & Troubleshooting] mythos234:
You can factory reset all day, it won't help. Thats not a problem, the camera just uses a lot of processor power and thus generates heat. You can't change that, you have to live with it ;)

My note 4 with ****y snapdragon heat like fire

I wanna replace it because of the overheating I can't something even hold it I put is always in freezer to cold it

With cpu temp app it gave me 60c even without games the :crying:best value was 40c but when I put it in freezer it down to 30c

And the weard thing that at the same time the cpu temperature app gave me 60c the cpu cooler app gave me 34c

Weard which is right? ??

This phone is making me crazy
[Galaxy Note 4 Q&A, Help & Troubleshooting] mythos234:
Sorry, but do you have any idea about CPU temperatures? 60 isn't bad. 40 isn't bad. 30 isn't bad. Even 70° and occasionally 79° would be acceptable. Don't put your phone into the freezer, ity not good to freeze the hardware.. Especially if you literally have no problem. The CPU is prone to temperature fluctuations and your values are fully normal in the world of CPUs. There is no best value, everything up to 70° is the normal temperature variation. Your phone doesn't have a problem, its perfectly fine.
[Galaxy Note 4 Q&A, Help & Troubleshooting] xurimx:
Mine actually heats up while charging and using at same time. Clean master shows 70-75°C cpu temperature while using browser and stuff but 80+ while gaming, that's not normal right? I'm worried cuz I always used my old phones while charging and they never got this hot, I feel like it will melt someday :/ In what temperatures exynos operates?
[Galaxy Note 4 Q&A, Help & Troubleshooting] wpkwolfseye:
I got my SM-N910F yesterday and installed LP 5.0.1 via OTA. Temperatures are 40+ when the phone isnt doing anything. While I did the Antutu Benchmark, it was around 50-52 degrees (Celsius). Feels much warmer than my previous Note 3 (which of course never had LP). And since i am not used to this temparature on my Note 3, i kinda worry about the temps right now. I read a lot that many have that problem since LP update. So whats normal and what would be too high for regular usage (not using Camera or playing Games) ? Is there an average i can go by and compare ?

And whats my alternatives now if I want lower temps , go back to 4.4.4 Stock Rom (currently have LP 5.0.1 Stock) or do I try a 5.x Custom ROM . Did the Custom ROMS fixed these heating problems or is that just something I have to live with ?

Thanks for any help.

My old G3 used to sit at 50 degrees idle!, 30 and 40 degrees is cool!!!!!!
[Galaxy Note 4 Q&A, Help & Troubleshooting] mru007:
Just do a Factory Reset (hard reset)

First backup everything & Google for detail instructions on hard reset.
[Galaxy Note 4 Q&A, Help & Troubleshooting] wpkwolfseye:
Sure that makes all the difference ? I read a lot of posts from people saying that a factory reset didnt really solve their problems. Do you know for sure it will help ?

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Aqualunguer:
So, here's what happened.

I have a N7000 and it's charger port stopped working a semester ago. So I bought a new one and replaced it. Everything went back to normal.

Now yesterday I was using my phone and it discharged (It discharges even while charging and browsing the internet for example), but I was talking with someone and I had to get back ASAP and conclude the conversation. So I took a older battery that's stuffed and pluged it in and finished what I was doing.

The thing is, now that I connect the newer battery (3 months old, original), I get stuck on a battery logo loop. The battery icon shows up with the circle that rotates in the middle, then the screen gets brighter, flickers a little (My phone always flicker at 25%~ battery) and goes black. Then it starts again and again in a loop.

The stuffed battery still works and is charging fine, with that said, I'm sure I don't have any problems with the charging port/cables/chargers.

I believe this has happened once before but I can't remember the procedure to fix it. Does anyone?

Thank you!
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] pdolton2000:
It almost sounds from what your describing like the charger block (not the cable itself) is not sending enough power down the cable, I would try either a different block or even a 2 amp charger block just to make sure.

[Moto X Q&A] carstenx90:
They cost about the same - if it wasn't that old, I'd go for the Moto X. But I guess it won't be getting updates much longer, and with CM you'll lose e.g. Active Display. What are your thoughts?
[Moto X Q&A] Darth:
The Moto X, IMHO, is the far better unit. Even over the G 2014. We're comparing budget devices to a former Flagship.

And as far as losing features on CM.... That's true. But the X is preferred by most I'd say, running stock with Xposed /gravity box for customization.

Again, all my opinion. ?
[Moto X Q&A] whgp:
not same cost Moto G in ebay 169-165$ \ Moto X 245-265$

of course Moto X better :o
[Moto X Q&A] wolfen69:
Heck, I'm getting a Moto X next Wednesday and I just sold my Nexus 5. I guess technically it's a downgrade, but I wanted the extra Moto features. If you're not a major power user, the Moto X is still a good phone. If there's a Moto X 2015, I'll probably get that at the end of the year. I would definitely get the X over the G any day.
[Other SmartWatches] caras2uk:
I have azgpax s8(android 4.4) and one of the best app is shake...sheke-it and the app is starting any app from your watch...another is acdisplay,which is a nice replacement for stock lockscreen(as a watch).Not bad is watchmacker(is for wear) but in connection with shake can be used as a watch.Any more interested apps for our smartwaches? Thank you.
[Other SmartWatches] Apokriphos:
I would strongly recommend SWApp. In addition, you must have rooted your smartwatch to take advantage of further battery optimizations and processor optimization.

Battery Op: You need a process killer/startup killer beyond stock. Many apps can do this.

You also need a way to monitor voltage, as many chinese smartwatches don't do this accurately.

Suggestions: Battery Doctor, Clean Master, with root permissions.

Processor Op: A way to modify processor speed, and # of cores running, to minimize always on app drain.

Suggestions:CPU Sleeper, Trickster Mod

Text to Speech/Typing Interface: You need an app that does text to speech, preferably offline. You need an app that allows you to accurately type on a small screen.

Suggestions: I haven't found anything yet optimal for this. I want to use Google Voice Offline, but haven't gotten it to work, despite following guides in XDA. Typing: I use a swype variant typing app. It works, but isn't ideal. Looking for more suggestions here.

Shake to wake:

I use Shake. It works well. There is also Shake Screen On Off FREE.

[8525, TyTN, MDA Vario II, JasJam ROM Development] jmat:
I'm assuming this is associated with the recent phenomenon of hardware ID's changing everytime a new ROM is installed. Apparently MS uses the same hardware ID when it encrypts files on SD cards. What this means is you will lose all of your files on the SD card (including backup files) if you have encryption turned on, the files get encrypted, and then you switch ROM's.

So.. uh.. this is just a little warning, and it might be obvious to everyone but me... don't use SD encryption unless you know you're going to stick with a ROM. :)

I have no idea why MS doesn't just use the IMEI, but... they don't.
[8525, TyTN, MDA Vario II, JasJam ROM Development] y2whisper:
From what I read about the encryption, the key is generated after a hard reset, so basically you can't hard reset the device once data is encrypted.
[8525, TyTN, MDA Vario II, JasJam ROM Development] ElePhone:
Do you know wether there is an option to backup ones key to a file, save it to ones PC, and then reimport it once one has finished hardresetting the device? :confused:

If I were MS I'd see the vast usefullness of such an option and integrate it at once ;)
[8525, TyTN, MDA Vario II, JasJam ROM Development] walshieau:
the encryption key is created when you turn the Setting on...

and when flashing a new ROM or a HardReset the key is desteroid...

i am still yet to find the location... still looking...
[8525, TyTN, MDA Vario II, JasJam ROM Development] Percz:
Providing you remember, can't you just turn off the setting before a flash or hard reset and restore all the files to there unencrypted state?

Once the ROM has been flash and everything hard-reset you can just encrypt them again?
[8525, TyTN, MDA Vario II, JasJam ROM Development] jmat:
No, because turning it off doesn't decrypt existing encrypted files. Just like turning it on doesn't encrypt the normal files. It will decrypt them as you open and resave them.

:-\
[8525, TyTN, MDA Vario II, JasJam ROM Development] jmat:
OK; that makes sense. I just realized that after I hard-reset I restored most of my settings with the data from a backup (Sprite Backup). I wasn't seeing the encoded files problem because I was restoring from a non-encrypted file.

ugh.
[8525, TyTN, MDA Vario II, JasJam ROM Development] jmat:
That makes perfect sense, actually. That way someone can't hard reset your phone to get at the data.

Too bad it also means the real owner can't get to his own data.. :)

Some FAQs from the horse's mouth: http://blogs.msdn.com/windowsmobile...ows-mobile-6-storage-card-encryption-faq.aspx
[8525, TyTN, MDA Vario II, JasJam ROM Development] bernardryan:
What you can do is ActiveSync your Device and then drag and drop all the files you want to keep before the hardreset. And then when you finish installing your ROM and Hardresetting your device, just transfer back the files via activesync. I know its tedious and long if you have like 1 gig of **** in the SD card, but thats the only way i've found.
[8525, TyTN, MDA Vario II, JasJam ROM Development] Steveborough:
just lost files to encryption

Been reflashing my 8525 with new versions of custels and vanilla and have never lost files to encyption. However just flashed to Black 3.01 and lost all my stuff. If i flash back to my previous ROM is it conceivable that the same key will be created and i will regain access to my files?
[8525, TyTN, MDA Vario II, JasJam ROM Development] keshen:
Unfortunately, I was also unaware of this. I presumed MS would use a key based on the hardware or something like that.

Anyway, is there any way of breaking the encryption and get back the files?

Thanks!

[8525, TyTN, MDA Vario II, JasJam ROM Development] MrGAN:
As the DataProtection API as in WinXP and Win2003 is used, it is AES-128 by default.

"The design and strength of all key lengths of the AES algorithm (i.e., 128, 192 and 256) are sufficient to protect classified information up to the SECRET level. TOP SECRET information will require use of either the 192 or 256 key lengths."

So brute force attack is not really an option….

As the key is stored somewhere in the flash I think this will be the only feasible way to decrypt the files.

But as the key is lost because of the hard-reset during upgrade, there is not much hope...

Only if we can get more information on how the keys are generated, maybe this will reduce

the complexity of an attack.
[8525, TyTN, MDA Vario II, JasJam ROM Development] JasenR:
You won't have good luck trying to crack the encryption. Which, is actually a good thing since the purpose is to keep your data safe in the wrong hands. I prefer to use a 3rd party encryption solution as it allows more choices and control.
[8525, TyTN, MDA Vario II, JasJam ROM Development] jmat:
Breaking AES is pretty hopeless unless you have access to the NSA's computer systems. :)

The big problem, in my opinion, is MS doesn't give you an easy way to back up the key and restore it. Now that I've given it more thought, it makes perfect sense that the key gets nuked on a hard-reset: otherwise someone could just hard-reset your phone and have access to your data. In most cases, it's better to permanently lose the data than to allow someone else to have access to it.

Another thing that MS would be wise to offer is a "mass decrypt" function that would go through the entire SD and decrypt all of the encrypted files.

Other than that -- the way I've been dealing with it is by using SpriteBackup (I'm sure SBP does this too) and back up the SD card along with the main memory. Since the encoding happens in the OS level, the backup software sees the normal unencrypted files. So this way I can restore the SD backup after a rebuild (I don't recommend restoring the main ROM image, since so much changes between each release).

j
[8525, TyTN, MDA Vario II, JasJam ROM Development] jmat:
Once you hard-reset your device and lose that key, your files are gone, unless you somehow have access to some very very high powered computer systems that can break AES -- and even then it would take several years.

I think the NSA in the US has managed to break AES (that's the rumor I've heard), but it takes quite some time.

j
[8525, TyTN, MDA Vario II, JasJam ROM Development] MrGAN:
AES-128 offers a sufficiently large number of possible keys, making an exhaustive search impractical for many decades.Correctly implemented AES-128 is likely to protect against a million dollar budget for at least 50 – 60 years and against individual budgets for at least another 10 years.

But as there are many pitfalls to avoid when encryption is implemented, and keys are generated.

So if the key is easy to guess it doesn’t matter if AES is secure ot not.

Creating good and strong keys is a surprisingly difficult problem and requires careful design when done with a computer. The challenge is that computers are notoriously deterministic, but what is required of a good and strong key is the opposite – unpredictability and randomness.

Provided that the implementation is correct, the security provided reduces to a relatively simple question about how many bits the chosen key, password or pass phrase really corresponds to. Unfortunately this estimate is somewhat difficult to calculate, when the key is not generated by a true random generator.

To make a long story short: if at all then the key generation might be the weak spot...
[8525, TyTN, MDA Vario II, JasJam ROM Development] F1forever:
So i've to realyze that i've lost all the data of mi SD card. That sounds incredible!!, i don't know if i will be able to recover all the changes made.

I installed Mobsync, wich makes me backups of the SD data to avoid SD corruption, but the files are also encrypted on my PC.
[8525, TyTN, MDA Vario II, JasJam ROM Development] JoeVulture:
WM5torage

I'm curious if anybody has tried turning encryption on, and using WM5torage to transfer files to/from the Hermes. Does it properly encrypt/decrypt the files, or does that work only when using ActiveSync?

Hi guys. Sometimes when i open my camera app it says Warning CAMERA FAILED and only thing i can do is to tap on accept. If i try to clear cache and data it's the same. I have to reboot the phone... sometimes after reboot all is good but sometimes don't. I have to reboot 2 or 3 times to get camera working again. If my phone doesn't power off the camera works as it should but if the phone is turned off rebooted etc, the camera sometimes work sometimes don't and i have to start again....

Anyone have this problem?

I have used mine for a week and it is slower than the Galaxy Nexus, which means that it is **** dog slow. I have reset it and there is little improvement, still very ****.

It is very very very bad. Not enough power to run SwiftKey properly even. The UI is bad. Games run very smoothly including GPU killers like Real Racing 3. I think a lot of the problem is not in thermal throttling, it's memory utilization. The more apps in memory it really does.

The g2 is many times smoother. Any phone available today is faster including the piss slow Samsung Galaxy V.
[LG G Flex 2] Applesexual:

Took mine back after 2 days the phone was laggy from day one and the phone charger would not charge the phone. Then today i went to make a call and the entire screen was black with color lines across the screen so i tried to unlock it and all i could see was a faded status bar . so on the way to Sprint i rebooted the phone 4 times and it finally came back on to normal took it back to Sprint and got a free replacement. The replacement phone i have now is so fast and lag free i can't believe it's the same Danm phone. This phone now is blazing fast and responsive the other phone i took back ran like a old s3 that's how bad it was doing anything. If all the flex phones ran this fast they would of scored a hit. but there's a few duds out there that's spoiling the party. If you have any issues with lag take it back and get it replaced before the 14 days. Had the screen not messed up i would of never known how fast this phone was when working right. Smdh i can't believe this phone messing up was a blessing. I mean it ran like **** i thought it was the software like everyone was saying it's not .
