Samsung Galaxy Note 4 Lag - Galaxy Note 4 Q&A, Help & Troubleshooting

I recently made the switch of my life to Android and I decided to go with a Note 4, since I tend to get quite bored, I enjoy
playing mobile games, but after reading about the lag I have been getting while playing a wide arrangements of games, I've decided to
try if downgrading from 5.1.1 Lollipop to 4.4 KitKat will resolve this issue, but will it trip the Knox counter and void my warranty?
I've tried other methods such as a full reset, but my issue hasn't been solved.
EDIT: Also, does anyone know of a direct link to download the firmware for SM-910W8? Thanks!

Downgrading my samsung galaxy s4(I9500) to 4.2.2

Hey guys i have a samsung galaxy s4 on android 4.4.2 kitkat and i am not happy at all with the kitkat update since it has ruined battery life and is causing many other problems like lag and overheating
So i want to downgrade to the stock 4.2.2. I have never rooted my samsung galaxy s4 and i am still unrooted.
I know knox will be set to 0x1 after downgrading but i do not care about it as triangle away supports galaxy s4 now .
So here is what i want to know
If i download the proper 4.2.2 firmware from sammobile according to my country(India) and install it via odin then will the process work? and if it is the right procedure does it require root ?
Is there any chance that my phone can get bricked because of knox ?
and how should i take backup of efs in case of a possible imei error ?
I know how to downgrade i9505 but i9500 Im not sure about it I never tested it out
I think you can downgrade successfully, I have a thread about how to downgrade from 4.4.2 to 4.3 but its for i9505 check my profile threads
You can downgrade successfully if you follow my guide, but you will lose wifi of maybe imei
So you can solve 4.3 wifi problem by downloading 4.3 kernel
You can use the same way to downgrade from 4.3 to 4.2.2
And for how to backup your imei you will need a rooted device !!
There some apps that backsup imei
Just look for your phone model "gt-i9500"
And you can backup you system starting from imei by having custom recovery like CWM and do Nandroid
And Knox will be tripped
Downgrade or Install Custom ROM

Hey dude,
I don't really understand how the s4 lags - did u try resetting the device?
the battery life is fine with the latest update.
Overheating is still there in i9500 & also it cools down rapidly - I guess its a HW design. Hope it wont be fixed.
I was annoyed with the overheating issue & now i am used to it. It heats while using 2G or 3G Internet & playing games.
Using regular apps it doesn't heats up & now i am okay with it.
Regarding the downgrade, frimware from sammobile will work fine. You will have to install via odin.
no your phone wont get bricked cos of knox - I suggest you to follow a video tutorial and do the downgrade.
But I recommend you to try a custom rom such as Omega, Hassan etc
In my experience the these roms are very good on battery and performance. Pls do note these roms (Omega, Hassan) are based on samsung stock rom.
If you still want to downgrade, I would suggest you to take it to the service center guys & they will do it for free.
Hope this helps!! :good:
Yeah it mostly gets heated while playing games and using chrome
Though i can still live with the heat because eventually i will get used to it after some time
But the lag is killing me
My phone shows lags while entering and leaving apps and camera and gallery too and it was not lagging before on 4.2.2
Also i have experienced significant battery drag
While using the internet it falls of by 1 percent every two minutes
Is this kind of battery drop normal ?
I am really missing the old firmware so i think i am gonna go to samsung and get it downgraded from there
Thanx for the sugesstion bro

I think will be not easy. You voided ur warranty when u downgraded (KNOX:0x1). No service centers will fix it (in theory) :highfive:
No Performance Lag & Good Battery Life

Hey bro,
In my experience with the S4 on Stock ROM I never experienced a lag.
Please check on the settings - switch off the gimmicky features such as Air View, Air Gesture, S Beam, Air Gesture, Motion, Palm Motion etc etc.
Settings --> Connections Tab --> NFC, S Beam, Nearby devices, Screen Mirroring
Settings --> My Device -->(scroll down) motions & gestures, smart screen, air view
Turn locations off
Check the battery graph - see which app consumes more
I had this issues when these features were on.
The phone will be always hot, battery was draining like 1 % for 1 to 2 mins.
There is no lag with camera and gallery.
Battery drag is bit similar that I lose 1% for every 3 to 4 mins on 2/3G Internet. But on Wifi battery is solid.
In my opinion battery is very solid in S4.
The latest firmware is very stable. The performance has increased from old firmwares.
If you hv rooted the device, and got custom recovery just try a custom rom.
Okay i think it would be good to try the custom rom
So i am gonna try that and see what happens

As I know, if you download an official firmware of samsung from sammobile, you can downgrade/upgrade your firmware without rooting, just flash via odin. Maybe you can uninstall KNOX first before downgrading, open KNOX mode and press menu and click uninstall KNOX. I hope this helps. Good Luck

[Q] KitKat vs Jelly Bean

Okay guys, this is not first thread about this subject but give your thoughts please.
I have:
Note 3 (SM-N9005) running some JB 4.3, unrooted
Note Pro 12.2 LTE (SM-N905) running KK 4.2
So far I haven't got any problems with Note 3, so kinda no reason to update it to 4.4, but does that update do more good or harm to me, since no way to dowgrade back.
About ext. sdcard writing problem, I haven't noticed anything that differs between my JB Note 3 and KK NP 12.2
Main reason why I would want KK on my Note 3 is Samsung SideSync feature (works only on KitKat devices) that I could use my Note 3 through my NP 12.2..
But is that really that good reason to update fully working phone (if there comes some problems with KitKat)??
Please help me with this, thanks

For me personally, I don't see more harms compare to the good parts.
I understand so many ppl do complain about KK firmwares. And to be frank, those problems stated, I have never experienced on my N9005 device (**touch wood**)
My ext. sd card writing also has no problem eversince I upgraded from JB to KK for the first time.
S-view cover, some also stated they experience problems, but my S-view is working just fine. And I have a fake S-view (made in China)
But all is your decision to make. My only advise is... if you really want to upgrade, after the upgrade is done, no matter you still can go through the homescreen, try to do factory reset from stock recovery. This step is very simple, but do help a lot to avoid future unnecessary problems (example : battery drains, FC, freeze, sudden reboot, phone very slow, etc).
So, my suggestions is, do backup of your important data (before upgrade) to your external SD, or to your laptop/PC.

yeah there few changes in KK update of N3
few GUI improvement
reason u may like to update is RAM management that is in native KitKat codes that of course others implements it.
:good:
Thanks, both of you..
I think I'm gonna update when I got some time to make all backups of my phone.
But let's see if this get some more replys and maby some pros/cons about KitKat
I have original S-View (which I do not use, since it makes phone too bulky for me), so I'm not worried about KitKat affects to those covers.
On my NP 12.2 running KK I haven't seen any issues with external sdcard so that should be fine.
(Possible??) battery drain issues don't scare me, and of course if I update, I'm going to make factory reset from recovery to make "clean" install
Last time I updated my phone, a day after I found URDLV, way to root without tripping KNOX. But obviously it was too late since that update patched bootloader, LOL.
I bet this wont most probably happen when going from JB to KK, that someone finds a way to root JB without tripping KNOX, but not for KK.
KitKat makes device faster/smoother (I've read somewhere, don't know is it really noticable on daily use?)
So what else you people have noticed running KK versus JB, any other cons and how about pros?

it is noticeable
Sent from somewhere under the sky, at the corner of this rounded earth.
Yep... So I pulled the trigger and updated my phone.
First impressions:
-It's a lot faster
-After update my USB 3.0 connection works no more to my PC (My NP 12.2 USB 3 connection also don't work, now I found what's the reason.. KitKat)
-My favourite internet browser force closes when trying to open it (I loved it since it was like ICS stock browser, got those must have fast button when you slide from edge of screen, it was fast and always on fullscreen exept when you opened adress line from fast button Does any of you know any similar browser working on (non rooted) KitKat?)
It takes 100++ years to get phone back to "usable" state (All settings, homescreens, app drawer, apps and they're settings, WIFI settings, paired BT devices...etc..etc....)
Let's see what else time shows me

[Q] GT-i9506 Safe root

Hello
My S4 got lollipop this weekend, (I9506XXUDOA6) and i want to root it without tripping knox. Is there any way to do this? Ive tryed towelroot or kingoroot but nothing worked
thanks in advance
I'm not 100% sure, but I don't believe you can downgrade the Android 5.0.1 modem to an earlier version and root using Towelroot. CF Autoroot still works, but it will trip Knox.
Yes thats the case.. I dont want to trip knox and i wont try to downgrade the modem.. Ok maybe patience is what i need
Im just facing some curious lags on my phone that have no sense... For example in the recent apps, on facebook, on messenger, and on swiftkey keyboard.. But i have to admit that battery is at its best. On kitkat with normal use, the phone was dead for about 20 hours, and now on lollipop for about 2 and a half days i guess? Does anyone know how to fix those lags or minimize them?
My main concern, and something I'll have to do further research into, is whether I'd lose my SIM unlock on an upgrade. I used RegionLock Away to unlock my S4 after repairing it. The unlock survived the restoration of Android 4.4.2, but I have my concerns as to whether it would survive an upgrade to 5.0.1. Especially as downgrading the modem apparently is not possible.
It might simply be easier for me to find a custom Touchwiz ROM and install it instead, but there aren't many of them as of yet.
Can anyone confirm that there is no way to saferoot a s4 lte-a with official lollipop?

Note 4 5.1.1 CF auto Root

Hi All,
I currently have a Note 4 910G that is still 5.1.1 with no OTA updates available.
I have been having dramas with my phone rebooting sometimes every 2 minutes, laggy and generally unresponsive.
I have backed up the phone the best I can as its stock and not rooted. However I was going to factory reset to see if it fixed the issues I am having. I have decided that root and flash may be a better option though as back up is horrible on android and also some added features would be handy (titanium back up and tasker).
My question is I am not 100% across what exact files to use as everything I find is for a different version. I found the CF auto root application, however, I am nervous that the kernel that is listed on their website is based on 6.0.1. I am finding it hard to find the 5.1.1 N910G Kernel to use instead
Will this cause an issue or does someone have the 5.1.1 kernel I can grab prior to flashing.
I hope this makes sense and any help would be much appreciated. Sorry if this has been covered, I have been searching around for a while and couldn't find this specific enquiry.
