If you think its just you, its not, I wanted to share this article I just found on SamMobile. I feel the headline says it all "It’s 2014, Samsung. Why does your software still lag, even on a flagship device?"

I'm assuming GPU Rendering uses more battery?
[AT&T Samsung Galaxy Note 4] imnoob55:
No issues here but I disabled all the ATT bloat ware the moment I booted it up. Mine is running like a champ, very pleased. This is with a few background monitoring apps for health and VPN.

Would suggest nightly restarts just to keep the phone fresh. Also would suggest disabling "Reduced CPU" under power savings even if power saving mode isn't on, have heard that stays on all the time.
[AT&T Samsung Galaxy Note 4] ok2nvnexus:
What apps r u using for monitoring ?
[AT&T Samsung Galaxy Note 4] imnoob55:
For health? Google fit, lark and s health. My Fitness Pal seems to also always be going but it's not doing anything except making the CPU get hotter.
[AT&T Samsung Galaxy Note 4] ronj1986:
I had lag on the AT&T variant as well as my current T-mobile variant. It mostly occurs when i press the multi app button on the bottom left of the screen. I originally thought it was because I have battery saver enabled , but I disabled it and that is not the case. Still lagging.
[AT&T Samsung Galaxy Note 4] naplesbill:
I can see a significant boost in UI performance when switching to the Google Now Launcher over TW. I am amazed how everything snaps and flows with the Google launcher compared to TW. This is on an ATT model.
[AT&T Samsung Galaxy Note 4] meanhacker:
make sure you're not on battery saving mode. also, can someone verify if the note 4 ships with Force GPU option enabled by default? Thanks. :)
[AT&T Samsung Galaxy Note 4] nyydynasty:
Mine was not on by default.

[AT&T Samsung Galaxy Note 4] meanhacker:
thanks, it would be actually kind of awkward if it was enabled by default lol.
[AT&T Samsung Galaxy Note 4] Cutetech:
I was having some lag overall last week - only had the phone a couple of weeks now - and turns out I had forgotten to turn off power save mode, lol. So yes, that does make quite the difference if you forget that you have it on. I'm running Nova Launcher, even though I do like the more improved Touchwhiz, but with Nova, the phone runs even better - smoother and faster.
[AT&T Samsung Galaxy Note 4] jalshah05:
No lag here, but could be an app doing this

To start off, I am using TouchWIZ launcher and everything stock. I have disabled tons of AT&T apps, but other than that everything stock. I usually do not start by downloading all the apps at once, I download only couple of apps a day and keep noticing my phone's battery life and lag in the phone in first month.

So far I found 2 apps that I used which created issue for me. 1) Magisto - Within 1 day of installing this app, my phone started running little hot and battery was dying a little faster. - Uninstalled it and checked for a day, everything went back to normal. 2) Ticket Master - Worst app ever. Within an hour of installation, I started noticing incredible lag, heat and battery issues. And when I say lag, basically it reminded me of Gingerbread days of android. - Uninstalled it and again everything back to normal.

There is one more app which might be a culprit in making phone temp go high and it is Inbox by google. I don't have complete proof yet, but I have seen it running in background even after exiting the app and taking almost 80% of CPU usage. I have noticed it only 2 times so far, so will keep an eye on that app.

Another thing I noticed with new TouchWIZ is that, it runs really really smooth without any type of issues at all for me. In fact I like TouchWIZ and the features it gives. I was using iPhone 5s for past 7 months and let me tell you that Note 4 feels even faster to me than iPhone 5s after getting iOS 8 on iPhone. Not by any means iPhone 5s is any type of industry standard, but I have noticed that iPhones always feel smoother than android phone due to the fact that no Apps run in background and no multitasking. But with this phone, this time, I have complete opposite feelings. I feel this phones is the smoothest phone I have ever tried after Lumia 1020 when it came out. I like to keep switching between platforms. :) But there is one issue that I found. Usually I love to create folders for all the apps from my app drawer. I usually have 2 pages filled with folders and all apps sorted out properly right on the home screen. But with this TouchWIZ, I noticed that once you have 2 full pages of folders, it sometimes has a very minor jerkiness while rotating home pages. But for some reason no matter how many widgets you put, it doesn't matter to this phone. :)

Last but not the least, my phone has been running like a champ without any sort of lagging or over heating. Love this phone.
[AT&T Samsung Galaxy Note 4] JasW:
Power save mode is off by default, or at least it was on mine. In any event, the Google Now launcher fixed the only real issue I had, which was an occasional glitch/stutter when swiping from the home screen to the following screen. (I never had any "lag," unless that little glitch qualifies, and unless we're counting the delay on the recent apps button when one has a number of recently opened apps.) A subsequent move to Nova and the "faster than light" animation settings was icing on the cake. Plus I got back the unread badges one loses with the Google Now launcher.
[AT&T Samsung Galaxy Note 4] jordant2:
I was using a rooted s5 with custom ROM and it was smooth as butter. This phone is awesome but there is some hesitation when launching apps for the first time, and definitely launching recent apps. I really think a part of it is just pushing such a high res display. If the display was 1080, the phone would probably fly. I never really say a phone has zero lag, every phone lags at times and I've used them all from the iPhone 4 -5s and HTC Evo - Note 4 (I switch every 3 months). This phone has some slight lag at times, but it is by no means slow. I'm sure the next update will make it purr.
[AT&T Samsung Galaxy Note 4] ShrekOpher:
Turn on ART. I get WAY better performance with it on and way better battery life
[AT&T Samsung Galaxy Note 4] jordant2:
You know I tried art the first day I had it and my phone got so hot compiling apps that I was worried. I ran it for a while but I swear it was running warmer, I could've just been paranoid. Then it would update for 2-3 minutes on reboot and get pretty hot in the process so I decided to wait for 5.0. So is your note running cool on art? Does it still update 60-75 apps on every reboot and get hot?
[AT&T Samsung Galaxy Note 4] nyydynasty:
I ran art for about a day or two and I didn't notice any difference other than some random app crashes, probably due to incompatibility issues. I switched back to dalvik and it's been butter.

Plus, I agree with the above. Reboots took almost 5 minutes because it was compiling all my apps.

[AT&T Samsung Galaxy Note 4] krips2003:
FYI... This also happens on my Nexus 5. Therefore it's not an issue with Note 4 but something on the at&t side. I too have to toggle airplane mode and then it comes back to LTE. I have also noticed this when I use runkeeper app during Walk activity. It'll pause automatically and then resume again due to switching back and forth with LTE and 4G.
[AT&T Samsung Galaxy Note 4] JasW:
I'm currently running ART, and I agree the lengthy reboot time is supremely annoying. But I don't reboot often, and I found switching to it did reduce the recent apps button delay to virtually nothing. Or let me say may have -- I also wiped the cache partition just before switching, so it was one of those two things or perhaps even both.
[AT&T Samsung Galaxy Note 4] nyydynasty:
I agree that ART did have some noticeable improvements but overall, it was nothing to write home about, at least not with KK. This might (hopefully) change with lollipop. I dont reboot often but when I do, its because something is acting up and waiting 3+ minutes to use it again reminds me of my Blackberry Pearl days....ughh:crying:
[AT&T Samsung Galaxy Note 4] jordant2:
OK so after switching back to art again, things are a lot smoother. The delay pressing the recent apps key is gone and the device feels faster overall. But now private mode won't work! I just can't win as I'd love to keep it on art, but I use private mode quite a bit.
[AT&T Samsung Galaxy Note 4] dazed1:
Art makes the phone MUCH faster, but it has some incompatibility issues, since at some times it lags out hardcore, like 1 sec pauses.....
[AT&T Samsung Galaxy Note 4] austin912:
how did disable apps/bloatware from carrier without root?
[AT&T Samsung Galaxy Note 4] threedfx:
Disabling apps doesn't require root. Go into Application Manager and find the app you want to disable, click on it and hit disable. It won't completely remove the app (uninstall) but it won't run and or show up on your app drawer.
[AT&T Samsung Galaxy Note 4] Techweed:
What type of incompatibilities are you referring to? I want to give ART a try but not if it breaks stuff that I actually use.
[AT&T Samsung Galaxy Note 4] joqsan:
When I was on ART I got random lag it wouldn't do anything for a good second and sometimes even force close the app that I was in. Switched back to dalvik and haven't had the problem since. Waiting for lollipop to fix whatever issues it has
[AT&T Samsung Galaxy Note 4] dazed1:
Random loading like pauses, it does makes the phone alot faster, but the occasional lag ruin the experience, that lags are because of incompatibility of ART.
[AT&T Samsung Galaxy Note 4] insang-droid:
I'm on my second note4. On my first note4 I tried switching to ART out of the box but it failed after rebooting 4-5 times. After that phone was dog slow, rebooted for no reason and apps just crashed. 4.4.4 wasn't meant to be ran on ART on this phone I guess.

I'm running on dalvik on 2nd note4 and haven't had the erge to switch. . Phone is blazing fast. Not perfect but so far my impression is best android phone so far. Surpasses lg g3 in speed, smoothness, battery, and sadly bloat.

[XDA Assist] RadarsCowgirl:
I hate to waste ur time over something that there is so much info on already. my issue is the low space msg. I have spent the past week reading and re-reading all the threads. The links for clockwork and unrevoked r dead ends. i have googled those files and i cant seem to find what i need. Im ready to pull all my hair out, and when im done doing that i think i may find a stick and poke myself in the eye, its gotta be less painful than trying to root this phone. I have put about 50 hours into this project and i am no closer to rooting my phone today than i was when i started. I love this phone, as a matter a fact i just bought it off ebay and changed from my iphone 4s to the incredible. i bought a 64g sd card thinking that would solve the space problem, and well as you know it didnt. Is there anything else u can tell me that might solve this issue? or help me with the files i need. anything??? Not being able to root this phone and complete this project i started is making me CRAZY!!!!!!!!! Thank you for your time, and i completely understand if u call me an idiot and demand i step away from the phone!! !Hahahahahahaha
[XDA Assist] Razvan:
Hi there,

Can you please tell me what kind of smartphone do you have, and exactly what you want to do?

Thank you
[AT&T Samsung Galaxy Note 4] mircury:
Chainfire posted a long writeup of what the future holds for root on Android phones including Lollipop. It's an interesting read.

"As stated above, it seems for now that modifications to the kernel package are required to have root, we cannot attain it with only modifications to the system partition.

Combine that with a locked bootloader (and optionally dm-verity) and a device becomes nigh unrootable - exactly as intended by the security guys.

Exploit-based roots are already harder to do thanks to SELinux, and now because of the kernel requirements for persistent root, these exploits will need to be run at every boot. Exploits that make the system unstable (as many do) are thus out as well.

It is now thus more important than ever to buy unlocked devices if you want root."

Edit: Tikerz beat me to it. His post is here. Mods delete if you want.
[AT&T Samsung Galaxy Note 4] JasonJoel:
No real surprise to me. It was only a matter of time before it got locked down to the point of no easy exploit. I'm surprised it took this long, actually.
[AT&T Samsung Galaxy Note 4] soraxd:
man locking bootloaders is one thing.. but root??!?

its not even a poormans route anymore to get a carrier phone over a factory one, you need to choose between functionality or reception..

i wonder if Xposed is responsible for crazy bootloader security moving over to root.
[AT&T Samsung Galaxy Note 4] funnycreature:
The lack of root in the foreseeable future really ruined my excitement for this phone :( I have gotten so used to all the nice features of root (in addition to custom ROMs) like Ti Backup, AdAway, customization, etc. that I do not want to fork out the money for a phone that doesn't feel truly mine.

That said, I'm confident the devs will find a solution. Just like every iPhone has been jailbroken there will be root for the Note 4!
[AT&T Samsung Galaxy Note 4] AcquiredIntellect:
There is a root for the note 4.....just not ours ...as intended...if we want root we bought the wrong device...I got it the day before it came out in the mail and was excited I wasn't aware that it was going to be so neglected...I was at least hoping for a safestrap like the note 3 I had that I don't anymore because it shattered and they gave me this as a replacement...now I can't get root...way too sleezy...they got me!
[AT&T Samsung Galaxy Note 4] JasonJoel:
I certainly don't see it as 'sleezy', as the devices were always known to be locked. It isnt like AT&T were endorsing root or safe strap in the first place... Or secretly locked it at the last minute without telling anyone.

But opinions on morality aside, it is disappointing that root may take a while. Though I'm still optimistic that it will happen eventually.
[AT&T Samsung Galaxy Note 4] funnycreature:
Do you have a feel for how long it might take? How many phones have there been historically that never made it? Cheers!
[AT&T Samsung Galaxy Note 4] pr0cl1v1ty:
Depends if you have a smart enough person with enough time / incentive.

Thus....the bounty thread we all made to hopefully catch a genius eye or 2
[AT&T Samsung Galaxy Note 4] ShrekOpher:
AT&T Note 3 still does not have an unlocked boot loader. I wouldn't hold out for one on this phone. Also everyone with locked boot loaders will loose root permanently when lollipop rolls out.
[AT&T Samsung Galaxy Note 4] fbauto1:
I agree with you but "enough time" could be a whole year
[AT&T Samsung Galaxy Note 4] californiarailroader:
Yeah, if you can afford it, for the rest of us though, it sounds like we'll be out of luck.
[AT&T Samsung Galaxy Note 4] mshinall:
Maybe we need to start looking at hardware hacks, like when chipping a console?
[AT&T Samsung Galaxy Note 4] cnote74:
Maybe an insecure boot.img can root this phone.
[AT&T Samsung Galaxy Note 4] ShrekOpher:
Focus on the boot loader. If it gets unlocked we will be fine with root.
[AT&T Samsung Galaxy Note 4] Why0Why:
Which is why I will be buying the T-Mobile Note 4 and unlocking. They already have root and TWRP.
[AT&T Samsung Galaxy Note 4] ThaiM:
At the very least, I just want AdAway to be functional. :(
[AT&T Samsung Galaxy Note 4] yogi217:
I may sell my att one when my bb pre-order arrives and buy a T-Mobile version...
[AT&T Samsung Galaxy Note 4] UniX1rm:
That would be the way to go if the bootloader will not be unlocked. It.will be like Playstation 3 .
[AT&T Samsung Galaxy Note 4] rans0m00:
nice having posts like this just right up front.... I come to xda for the modding and mainly rooting of my phones.... att releases a totally locked down note 4 and already people are speaking out about its probably not going to get an unlock like the s5... I give up all hope of seeing a subsidized note 4 and start waiting on a nexus 6 to see if the bootloader is still unlockable.

So within 3 posts and less than 15 minutes I learned abandon the att n4... quick and easy... ty xda :highfive:
[AT&T Samsung Galaxy Note 4] jacklex13:
Im coming from the S5 I have faith in the Devs here in the beginning with the S5 seemed like all hope was lost and then out of nowhere root was available. I'm going to enjoy the device and give whoever has the means enough time to do their thing it will happen eventually
[AT&T Samsung Galaxy Note 4] 903tex:
People enjoy the phone. Most likely the note 4 will never be unlock bootloader and maybe will have a root exploit down the road.

Overall just enjoy it. If you don't want to wait go the tmobile route and unlock that model.
[AT&T Samsung Galaxy Note 4] WizeGuyDezignz:
I'm personally sick and tired of hearing about root and the bootloader on this phone.

You either knew what you were getting into when you bought this phone or you didn't. If you knew what you were getting into, then don't complain. If you didn't know, do more research next time, return your phone and quit complaining.

It's super easy when you think logically. I just hate when people complain and act like they were owed root and a bootloader unlock. You weren't.

I want root and the bootloader unlocked just as much as the next guy or girl. At the same time, I knew exactly what I was getting into when I let my rooted S5 go in favor of the locked down Note 4. And I'm totally prepared to never receive root. It was my choice and I will live with it.

There are tons of other phones and carriers to choose from. Good luck to all and thanks for reading my rant.
[AT&T Samsung Galaxy Note 4] chaosjh:
Not that I've been complaining but I disagree in part. I do want root of course, and hope it will come sooner than later. There are several functions on a phone I cannot use without root. Air stream is one I use every day I'm off to listen to music. Sixaxis I use to play games. I use xposed app settings to make use of in house apps made only for tablet. I use other apps as well that require root. Am I owed it? No, but why lock it? Apps can be stolen without root, warranties don't have to be fulfilled if tampered, and great minds can create ideas for future software ideas. I'm mad that is locked in the first place. I also disagree with your statement of just getting another phone. I like this phone. I think it's the best. So why would I want to downgrade? No thank you, just don't lock the phone to begin with. /rant
[AT&T Samsung Galaxy Note 4] silentecho13:
I honestly just want to fix the SD card issue with kitkat. I bought my phone prepared for not having root but I had no idea the SD card would be an issue. Now, it seems like root is the only way to fix it.
[AT&T Samsung Galaxy Note 4] WizeGuyDezignz:
My point is why be mad? Being mad is your personal choice, but you aren't owed root and being mad isn't gonna get you root.

If you like this phone and "need" root, why not get the T-mobile Note 4? Otherwise there's not much you can do but accept what you have. No need to be mad and bring more emotion and stress into your life that you don't need.

Just my opinion, but whatever floats your boat. :thumbup:
[AT&T Samsung Galaxy Note 4] 903tex:
Everything is security. We xda users only make a small dent in what normal users of today's market are. Security sells, it what most people care about with these smartphones cause their basically computers that make phone calls. Eventually it's to the point where if you want a unlocked device you have to go thru Google and get their phone selections.

I want root and custom roms just like everybody on here. But I knew walking in to the att store and getting the note 4, that I would most likely never have that on this phone! Does it suck? Hell yes could I have just bought the tmobile n4 and unlock called it a day? Sure but I didn't want to go that route.

Long rant but I agree with guyz. IMHO these bounty threads are mostly pointless....
[AT&T Samsung Galaxy Note 4] 12MaNy:
You mad bro? :p

I think its atrocious that this is happening......but rooting and patching exploits has been a game of cat and mouse for years. We exploit holes in their security (in order to obtain root) and they patch it up with OTA updates. Now...SELinux is has been implemented......and SELinux is kind of like those "agents" in the Matrix. We just need to figure out a way to be Neo.

It also doesnt help that these huge bully corporations steal people from our community to help them patch up their overlooked renderings. ;)
[AT&T Samsung Galaxy Note 4] fbauto1:
I agree with you completely. But stealing people from our community is just part of the business.
[AT&T Samsung Galaxy Note 4] pr0cl1v1ty:
agreed.
[AT&T Samsung Galaxy Note 4] jlczl:
This is exactly what I've chosen to do. I didn't think I'd need root because I never expected lag on my Note........but it's there (scrolling and hangouts) so off to the root route I go. That means returning my at&t version and getting T-Mobile's version.
[AT&T Samsung Galaxy Note 4] SysAdmNj:
Will Tmobile's work on At&t ok? And will Tmobile sell one off contract? I mean I do have a prepaid account with them for work. But my main line is on At&t.

[AT&T Samsung Galaxy Note 4] 12MaNy:
My point was...in essence, we are one of the security threats that they "inadvertently" protect against. So, the fact that they hire people from our community to seal up the cracks in their software is both ironic and eye opening. The people they hire from our community end up being "double agents"...so to speak (which is a good thing). It also tells me that sometimes the people that bully you need to come to you for help. It's an awesome, yet annoying feeling. :)
[AT&T Samsung Galaxy Note 4] fbauto1:
Yes. I truly understand your concern. I too, am a business owner. If the "best" people who fix my problems are on the "other" side of the fence, I'd hire them too. Like I said in my previous posts, this is just how business goes.
[AT&T Samsung Galaxy Note 4] 12MaNy:
Yes. It is normal for employers to scout talent, but I'm pretty sure the other business owner would be pissed if you took his/her elite employees......especially if you hire them specifically to help screw over the former employer.

In that instance.....it's not "normal business". It's a f****ng slap in the face.
[AT&T Samsung Galaxy Note 4] fbauto1:
Huh? Its totally obvious you're not familiar with how big companies work. If I can get the best employees of my competition, I would do it. Money talks in businesses, not feelings. Its not what "feels" right, its about what and how it can affect the company positively. Its the exact same reason as NBA owners do. Its f*****ng business. If u can't comprehend that, then there's nothing else I can do. They are hiring people, not kidnapping and forcing them to work. If you keep thinking businesses shouldn't do this or do that, you should never own one.
