[Q] Phone arriving tomorrow, some advice please - Galaxy Note 4 Q&A, Help & Troubleshooting

My SM-N910F arrives tomorrow. I guess ios the Qualcomm device, I live in Italy.
Some advice please
1. Many experience worse battery usage with lollipop and advice not to upgrade from kk4.4.4., is it still so? For me battery drain is a problem, my Note 3 last half day, because of very heavy usage (8 email accounts, 6 messenger programs, many calls, many whatsapp/viber call messages, and so on)
2. Rooting. My only wish is to use GMD Gesture (or similar) in order to use device with one hand. Is rooting obligatory, or there is another program, or? If obligatory, is it possible NOT to trip knox?
3. I never liked touchwiz and always put Nova Launcher in my previous samsung (S3, Note 2, Note 3. Is it still the same?
4. other advices?

hi ,
ok, this is my "take " on the n Note 4 N910F ................
I have a Note 4 N910F ,rooted ( since October 2014 , hours after i got phone and on Android v4.4.4)
I am now on Lollipop BOC5 ,with custom recovery CWM and stock ROM .( i have also been on previous/ earlier Lollipop versions ...BOB4 and BOC3 ) I am a meduim user .
So, I think i can give an opinion about how i experience/find Lollipop ???
My battery life has always been good ,across all versions from Android v4.4.4 up to now .My device is running very smooth and have no lag ..apart from recent button and one other small "bug " ..thats it .I have taken note of members complaining about poor battery life and this is very strange to me.
Yes, i have had odd battery drain ,but managed to id "culprit/culprits " " and its always been an 3rd party app that was badly behaving or an setting ( location ...etc ..)...maybe i am lucky ?.....NO .
I also have an Note 3 ,rooted ,stock Rom etc ..No problems, battery been good, running smooth .. etc etc I also have a Note 2 ,rooted ,No problems ...........................................
I would say your battery usage, should be the same as your Note 3...( my take )
as this is what i experience between my Note3 and Note 4 .
2.....Rooting, i rooted from day one with Chainfire CF autoroot and still up to Lollipop .I am personally not obsessed/care " about Knox .I don't need Knox and use a Nortons antivirus on my phone ..been for years and happy with it ..I do however respect members viewpoints ,that do worry or care about Knox.
I also use GMD gesture on LollIpop. ( and joined the app beta testing program )
Its is still a little " buggy " here and there ,but works mostly fine for me !
3.I have Nova Prime on all my phones and don't use Touchwiz...No problems .
4. Surely ,if you encounter an issues , you should be able to short it out .....?
Bottom line ..its your device enjoy it .
Good luck

Other advice is not to root the phone before you are 100% sure all hardware works flawless.
It would be a shame sending a faulty device in for repair for something that could have easily been avoided by proper testing, then have your warranty rejected because you rooted it.
And of course when you root, make proper back-ups.
Also getting a screen protector and a nice cover should be recommend.
I'm using the Samsung S-View*flipcover and enjoy it a lot.
Kind regards, Stefan.

I agree with ThaEvilOne, make sure you test the phone for the first few days first before you root. I never rooted mine, just disabled some Bloatwiz, and I get great battery life. In fact we have two N910C in the family and both last a day.

thanks, but you should see GMD gestures what does to your phone, is an amazing program.
I agree will need to check is 100% working before rooting
BTW I bought it from Amazon warehouse delas, and saved 100 Euro, I hope nothing is faulty with it

To all.
How to check that is 100% working, beside using it a lot. There is maybe some downloadable app that checks that all the phone is fine?

The phone is perfect but KNOX counter is 0x1, the bastard using Amazon warranty gave it back like this (I bought from Amazon warehouse deals).
I paid for it 525 EUro.
Suggestions?
New it costs 570 Euro, maybe waiting some weeks usually you can find it for 530 Euro (NEW).
ALthough I was thinking to root it so ......

share your experience to help me tranfer from ios

hello dear xda community!
it has been a while since i was last here.
i owned a gs2 but made the move to ios with iphone 5 and currently use iphone 6.
I am considering buying note 4 (c variant with exynos)!mostly for the great screen ,battery life and not overheating( almost all other androids can cook your hand)
i lurked around here to do some digging and i keep seeing members having big problems with battery drains, overheating and slow down...( i will be skipping on note 5 as it will not come to europe and mostly because of no removable battery-micro sd)
have i missed something? is the big res scree bogging down the phone?
owning an iphone, performance is a given for me.
Please share your honest views since you own the device and help me make the move!
got sick of same damn thing and restrictions (ios)
My best advice to you would be stick with iOS. I own Note 4. Previously owned lots of flagship android phones and before that iPhone 3GS, 4S and 5S. I will shift to 6S when it will be available in my country because I am tired of bloated SW solutions from big firms and sick of flashing custom roms that almost never match the performanco of camera with stock. iOS is still the best SW you can get and I will stick with it for a while.
Regarding android IMHO Note 4 is the best you can hope taking other 2015 flahships in mind that are not worth the upgrade specialy with SD 810, no microSD and non-replacable battery that is getting smaller and smaller despite constant *****ing about it's insufficiencuy. With latest 5.1.1 it is realy fast, takes great pictures and battery life is awsome. I have no problems with it and till now it is as close to iOS experience as it gets.

For the OP!
Stick whit IOS my friend ....
My 910f is realy awsome whit 5.1.1, no overheat, no lag and superb battery, but ios much much better in stabiliti and before android 5.1.1 it has better performance.
you see, the thing is..what made me consider moving was the hideous battery life (iphone battery is epic bad-like..bards would sing of its loussiness).
and couple more every day stuff that really halt your schedule( try attaching two different file types-say 1 xls+1pdf on same mail in ios)
i guess i was hoping that it would be better with note 4, but from what you guys say it lacks stability on a very profound level..

hi ,
i guess there always 2 sides to a story . ?
I have a Note2 , Note3, and ... Note4 ( ........cannot say anything much, about Note5 ..!!)
All my devices battery ( removable ) life is good/acceptable , no overheating , smooth running and customized to my liking !!!!!! This is what i want and enjoying it .!!
I do not own a Iphone and thus cannot say much about it .!!
(Yes ,i have "played around " a few times ,with a Iphone in the phone shops and know its overall feel and workings )
Everytime i just put it down and say no i am happy with my Note4 .
All i can say is , in the end it is "what you want from your device...its you choice ."
So is it an an option ..... to have/own both ?
i want freedom of choice, ( customize etc ) and cannot see myself been tied down .
My message is only ,there nothing "wrong " with Note4
Hardware ,specs , removable battery and to do real multitasking on a device ? ...etc
Also i am on Android v 5.1.1 and device working very, very smooth .No issues .
However i have noticed some forum members have /had certain issues
good luck with your choice .
post entry
my observation of reading post and " my opinion" ,
regarding battery drainage in Note 4 is that a some members have either
3rd party apps or wrong settings or some" mod/theme " on phone responsible for this ( yes, i know not always ) eg facebook, whatsapp , gps location enable ,data always on ,etc... in some setting etc ( battery drainers ) or just badly coded apps or games .sucking away on battery.I had Note4 since October 2014 and had odd battery drain and always ( when investigating ) found 3rd party app or mod eg Xposed framework or module etc responsible for this .
Bottom line ,
is you only read mostly in threads, when members have a "problem " and hardly read post of members that is happy with performance/etc of device ?
good..this is what i want to hear..opinions based on real owner experiences!
just one more question!
is it true that since knox , i cannot root the device without it being permanently recorded? i mean, i remember being to erase such things on gs2 with stuff like triangle away app.. i dont care for flashing roms, rather than using my paid titanium app, adaway,root explorer and be able to freeze bloatware.

hi,
yes, thats overall true eg. if you use dev @ chainfire CF auto root it will trip Knox.(this CF auto root method, is what i used overall. except in Android v5.1.1 it does not work so i used another method ) However you do get certain root
methods that won't trip Knox.
Don't ask me what method as i really was never interested in rooting this way.
My personal opinion of Knox is.. i see it as a "bogey man" it does not worry me as i got no interest in Knox features. .. or the attitude... "o what is Samsung warranty going to say.?"
That said...
I do however respect other members view on Knox.!
I wanted to enjoy my user experience and rooted my device way back in October 2014... never looked back.
My viewpoint is,
If something "happens" well then it "happens" an i will deal with it accordingly or get another device.
I just wanted you to get my viewpoint over, that overall Note4 is a very, very capable device..good at multi tasking, good battery use (overall) no overheating issues and very smooth and fast (just tweak right)
Good luck with your choice
to be honest as long as it works and battery performs , i am happy camper..i am familiar with androids plus and minuses..
I wouldn't get it now. On its stock rom the dpi is way too high, everything is so big on the screen and there is no added real estate from a phone such as the S6. As for performance I've never been happy (N910F) until 5.1, but on 5.1 I can't use per app dpi. Do not throw your money at Samsung, opt for a Moto (or even the new Sony Z5 series), they're much more consistent performers. You could even wait for the new Nexus 5 or 6 coming out next month which will have biometric sensors. The one on the Note 4 sucks haha.
If you want to use the Samsung apps then stay with Touchwiz and root it, I would currently recommend using this ROM
I know you said that you are not into flashing ROMs but I would recommend that you give CM a chance or if you want extra personalization then try other custom roms.

i'd have no problem with flashing but custom roms never really get the camera app right or work well with ril files etc..
CM is very far from my taste although it has a sink ful of features.
i am almost set with giving up the iphone 6 for note 4.
just gonna wait till ios 9 gets previewed on wensday.
cant wait for a note 4 like battery, coming from i6.

I was not really happy with my Note 4 N910C until 5.1.1 came around.
More happy when I installed a stock pre-rooted ROM from Wanam and ultimate kernel then installed Note 5 theme and multi dpi for app.
My phone is very fast now, great battery too!

Still buy a Note 4?

Hello guys,
I hope it's not a too stupid question, but do you think it's still a good time to go for a Note 4?
At this moment I have a Sony Z1 and I want to buy a new phone in december.
And for now I really like the Note 4. The only thing that is scarryng me is knox. Is the lost warrenty the only thing you lose with root and bootloader unlock?
On the Sony's you also lose features and camera is getting worse... What's about Samsung?
Also I'm interessted in AOSP's... Are they stable and support all stock features? (There are really a a lot^^ without trying it's heavy to say)
I also ask because on the Z1 there are no stable AOSP's and CM is still buggy.
If you thing it's not a good decission to go for a Note 4, would you recommend another phone?
I'm sorry for my english and also sorry if I said something wrong or stupid.^^
Thank you!
Go for it. You wont regret it, trust me. (just bought a note 4 lay week coming from a s4)
If interchangeable covers (like flip covers with clip-on battery cover), removable battery and extra micro-sd slot are things that you care about, then YES, definitely go for Note4.
If the above list is "meh" for you, then go for Note5. If the S-Pen is not something you are chasing, then S6 edge plus may be a viable option as well.
I just bought my N4 2 weeks ago and I have mixed feelings now (coming from a Z3 Compact). The little Sony is way much faster and fluid compared to Note4 (even with the 5.1.1 update). Other than this, yes, Note 4 is a good device, actually brilliant for business use (I'm actually using it to take notes during meetings).

Nothing is gone if you root Note 4....you'll get way better instead.
But....in my opinion, AOSP on Note series is a waste, because it's removing all it's built in features.
In the last update (5.1.1), even it's stock ROM is awesome.
All TouchWiz lag is gone, but you must flash custom permissive kernel to root it or you'll stuck in a bootloop.
But even the bootloop on stock ROM after rooting is easily fixed by re-flashing the ROM.
Remember that Samsung Galaxy Note 4 is not an ordinary phone, unlike Sony Xperia Z1.
What makes Note 4 special is its stylus.
Currently I'm using Googy Kernel + Stock 5.1.1 for my N910H + TWRP recovery + LED Cover / S-View wireless charging cover.
...and yes KNOX counter will be tripped if you root or flash custom recovery & warranty void "officially".
But some said that they can even get a replacement device even after rooted when the device is broken.
Who knows...
I hope my information helps you
EDIT:
Some say that the camera is worse in AOSP.

Just an FYI, don't buy an n910a (the US ATT model). It isn't rootable due to a locked bootloader, so you be able to do any of the stuff you mentioned in the OP.

Go for the Note 4 . 5.1.1 is smooth as hell and all the Touchwiz problems are gone ! Note 4 has the best looking display , Be it saturated AMOLED Cinema mode or the BASIC mode with perfect colour calibration . The camera is out of the world . It is very well implemented . I get 24 hours of usage with 5 hours SOT easy with HSPDA . With the Super awesome Screen , out of the world camera , swappable battery , MicroSD card it is by far the best deal .
Go for CM12.1 for Stock experience , Also I dualboot CM12.1 and stock so that I get best of both the worlds . No other phone attracts me after I bought the mighty Note 4 .

Note 4 [SM-N910F] : Considering moving on, lag and poor experience....HELP!!!

Hi Everyone,
I'll keep this short...I've had my Note 4 for about 10 months now. Generally I have to say I feel that I've been living in denial, I love the device from a HW perspective and also the S Pen features however the SW is just too damn clunky, laggy and slow. Right now there is 1 to 2 second delay before it responds to any gestures + this can be up to 5 seconds when launching the camera for example. Also when playing music via Bluetooth it is very choppy and cuts in and out of the track being played (I have tried this on more than 1 Bluetooth device and its the same). When updating to Lollipop it seems that the experience hasn't got better, infact probably worse. I've loaded another launcher (Nova launcher) to see if the problem was touchwiz however its still the same. Lastly I've reset the device to factory 3 times now, which helps however it doesn't take long for it to get back to its usual clunky self. With all of this in mind, I am seriously considering moving on to another premium device however I wanted to throw this out there to you all to see if there was anyone else who had experienced the same issues and even better had a resolution.
Should I root the device and install another rom or simply move on???
Any help is much appreciated in advance.
Thanks,
OB
Try root and try a rom. There are a few out there that have been through the paces
Try another rom, I'm on dn5 and my phone is incredible fast

Thanks for the replies guys. I have a 910F, sucessfully fully rooted it today. I am looking for a fast and reliable ROM which also has the S Pen features. Can anyone recommend one instead of trial and error. Must be 910F variant.
Lastly, do I need to do something to a bootloader or something in order to load the ROM? Apologies if that's a stupid question...I am still quite new to this and learning.
Thanks,
OB

What about your battery performance? I have the same model and it's very bad!!!
I had the same feeling when I got my N910F a couple of months ago (coming from a Note 2 which I felt was more responsive and snappy than the Note 4).
But then I upgraded from the original 5.0.1 to stock 5.1.1 and it's like having a new phone; no more lag, or stutter or delays. This is what the Note 4 should have been like from the beginning.
So I suggest you try first upgrading to stock 5.1.1, no root and Knox intact at 0x0.

My battery last around 9 hours with 3 hours SOT with very heavy use :
Youtube
Radio streaming
Music
Gaming
Many syncs (Outlook, Yahoo mail, Gmail, ICQmail, Instagram, Twitter, BBM, Periscope, Skype, Instructible, Facebook, Facebook messenger, Whatsapp, Line, G+, Path, GTalk, Hangouts, Mega, Dropbox, 4Shared, Box, Drive, Onedrive, Youtube, Sing!, and many more)
For Cloud storage I sync some folder on access using FolderSync.
Downloads
Web browsing for around 1 hours
Some note taking.
WiFi, GPS, Bluetooth is always ON
With medium usage it can lasts for around 13-16 hours.
With light usage it can lasts for 18 -20 hours
With very light usage it can lasts 34 hours max (only standby+music+5 minutes web browsing).
It used to be 42 hours during very light usage, but it's been 1 year so the battery is degrading.
I didn't mention phone call because many of my family members & friends use BBM/Whatsapp/Line/Skype to call me.
I only use a real phone call for less than 15 minutes a day so it's negligible.

Note 4 Auto Reboot HELP !!!!!

Guys, I preordered my Note 4 when it first became available and got the phone at the earliest in my country. It's a SM-910G. I used a lot of custom roms but TW always had the best battery performance and features for S health and S Pen etc. But my phone keeps on auto rebooting on the latest official TW MM rom from Samsung and it wasnt even rooted, updated regularly. but when the problem persisted, i bought a Stalion battery from amazon as a lot of developers suggested. It went ok form 2 months. Then the issue continued. switched to Lineage and also downgraded to official KK, LP roms from Sammy but all in vain. Samsung Servicing asks aroung 320$ to fix the phone. Partial Wake Lock did not fix my phone. Please help.

Sounds very much like the eMMC_read failed issue.
See:
https://us.community.samsung.com/t5...ePhones/thread-id/12183/highlight/true/page/1

https://forum.xda-developers.com/note-4-tmobile/general/ddi-mmcread-failed-boot-error-fix-t3434335
In my case it started out exactly like yours, I bought a new battery (official Samsung), in my case because the camera app seemed to crash out and cause a reboot, I suspected a tired battery. Then a few months later it went downhill, and fast. Started out with perceptible "lag" in some apps, then full-on freezes (everything just stopped in it's tracks for a few moments - eg a page-swipe in the App Drawer, or scrolling a web page). These then started to be followed by spontaneous reboots, until one day I got the "emmc_read failed error".
I did not try the wakelock sticking plaster. I wrote to Samsung and convinced them to repair my phone FoC despite being a few weeks out of warranty. It's with them now, I'll see what it is like when it comes back.
Bonne chance.

[Q] New Samsung Note 4 owner, things I should know?

HI all.
I'm a new Samsung Galaxy Note 4 owner! Recently upgraded from a Note 3. Phones are years old but are decently priced and still good phones when you're not looking for something too fancy.
Honestly, the Note 3 was the best phone I've ever had and was looking forward to a Note 4 upgrade (was looking forward to the fingerprint scanner, even if not the best, and to the metal edges)
Now, I'd just like to ask for a few pointers on this device. Any custom ROM suggestions? Anything I should know about?
I am doing my fair share of research, I've been reading a lot of posts regarding this device, posts that are months old, posts that are years old and I've gotten myself a general idea of what to expect.
But I think even with all this reading, I probably won't be able to compare what I learn from these posts to someone that has owned a Note 4 for months, possibly years! Which is why I'm posting this thread, to ask those who have had this device for a longer time and will probably continue to use it for a longer time since this phone is amazing!
I just want to ask you Note 4 owners, if you bought a brand new Note 4, what set-up will you prefer? Custom ROM? Stock ROM? Any kernels you would flash?
I know the best ROM will always be stock ROM, but is there any worth-while N7 ports for the Note 4? I'm a big fan of the off-screen memo, the smart screen capture (scroll and screen-recording that records gifs) and also enjoy tweaking the kernel (overclock) for smoother game performance. I've also read that the most common problem with ports is the fingerprint scanner. I'll probably end up doing the work-around since no custom ROM has gotten this fixed (from what I read it's almost impossible without leaving a lot of the stock ROM's assets which defeat the point of a custom ROM).
Currently, I am downloading stock EQI2 6.0.1 which is the latest firmware for the N910T variant. I know that the T-Mobile variant has it's own forum but I usually see that the "Samsung Galaxy Note 4" thread is the most active and sometimes includes things for the T-Mobile variant (was the same case with the Note 3, the T-Mobile forum was dead and the international forum was alive and well)
It's running 5.0.1 software right now, hopefully 6.0.1 is better.
Thank you for your time!
I kindly invite you to try the unified trlte build linked in the [ROM] [UNOFFICIAL] [7.1.2] LineageOS 14.1 [SM-N910F/G/P/R4/T/T3/V/W8] thread.

Thanks for your input, I am currently trying out a Note 7 ROM port, but if it doesn't work out I will try it out
Personally, I prefer to run the stock OS that comes pre-installed on my device and update the OS to the latest version provided by the manufacturer. As I know for a fact that Custom 3rd Party OSs do not have the best post imaging software. Which hinders the performance of the camera sensor on your device.

Been snooping around and messing with a couple of custom ROM's either with Note 7/8 features and S7 Edge/S8.
I really like the look overall to the stock Note 4 UI, but I seem to have a very bad luck with random reboots and some features missing (fingerprint) or not working (night clock).
I was really afraid my phone was doomed with the eMMC failure I keep reading about that plagued the Note 4, but I don't have any problems running stock.
Yup, I guess my motto came true. "The best ROM is always STOCK ROM", even if it looks a bit out-dated.
I'm currently running stock and a custom kernel I found for stock MM. I'm pleased with the results so far, just kind of wish I could boot straight in to camera with double HOME press
Best advice I can give you , owning the phone for 2,5 years, is to never use quick charge and never update the phone or flash custom roms while the phone is being charged.

That's interesting, the first time I've ever read not to use quick charge. What particular reason do you have to suggest this?

I am amazed you are not aware of the motherboard brick problem of the note 4 !
Do a quick search and read about the motherboard Emmc problem on a lot of Note 4s.
Cheers!

I did read about it, I just wasn't sure what was the root cause for it. So I guess fast charge is the culprit? Every place I read this people seemed to blame an update either from KK to LL, or from LL to MM. Wow... I gotta think about this one. One of the reasons I love this phone over my Note 3 is because of the quick charge. Man :/
Gotta think about trading that feature in for... you know... a FUNCTIONAL PHONE :laugh:

IMO the culprit was a heavy update(eg. from lollipop to Marshmallow) being installed , while the phone was pluged in being quickcharged.
This pushed the temperatures to exceed the max threshold of a bad emmc solder on the motherboard on some specific batches of the note 4.

So you think regular quick charge should be fine? The phone doesn't heat up with regular quick charge, so I really hope it's safe. I know that just to be safe, I shouldn't use quick charge. But I guess I'll roll the dice.
I updated from LL to MM via Odin, so it wasn't quick charging :victory:

In my case , my phone gets really warm while being quickcharged even if I am not using it at all.
I live in a warm place though!
If you want to use quickcharge , I suggest you go ahead and use it but without using the phone during the charge.

Yeah, I'll take my precautions. Thank you for your input
I have an exynos version so can't tell you much about the snapdragon versions (also never heard of emmc problems on exynos devices, the only problem I have is IR blaster stopped working some update ago and never worked again since), but here's little general advice :
Stock ROM is perfectly reliable and very smooth with little customization :
I recommend a package disabler app like EZ disabler to get rid of bloat. I disable anything that doesn't have a clear use for me . If something breaks functionality I enable it back.
If you don't want to root you can use adhel to block ads in very efficient way .
If you do want to root I recommend magisk . It's the best way to do it because if anything goes wrong you can just uninstall it and everything is fine again , it doesn't affect system partition.
Also system less xposed works great if you use the proper version . I love youtube background mod.
In my experience you should never use apps that claim to save battery like amplify/greenify etc . (In some cases they drain the battery even faster with their continuous background services) The better way to save power is to not install power hungry apps in the first place or disable them with EZ disabler . Also disable animations and just disable functions when you don't use them : Sync/Location /Bluetooth etc .
Last but not least : download and use Samsung game booster : it's amazing for our old gpus : you can lower resolution/frame rates to make games more playable and battery last longer .
These were my quick tips . Hope you enjoy your new phone !

The only small problem I have with stock is that it looks outdated. I know visuals are the least you should look for in a ROM, should be more worried about stability and battery life, but I simply can't deny that visually, stock TW UI bothers me.
But I guess I'll have to get used to it anyway since all the ROMs I've tried have issues here and there, but most importantly I get random shut downs and reboots with most custom ROMs and I lose the fingerprint scanner.
As for games, I heavily play a game called Shadowgun Deadzone. It's not that graphics heavy, but I need it to run smooth. I haven't tried Samsung's game booster, I've only messed around with custom kernels and changing the CPU governor, overclocking, etc... and it runs fine for a little while, but starts chugging after a few minutes in.
If the game booster can fix this, heck I can stick with stock ROM without any problems.
When you say it looks outdated
Are you talking about the launcher?
If so why not try the many other launchers out there? Like nova launcher..

A launcher can only do so much. I'm referring to mostly on things like the notification drawer, the settings and stuff like that.
