Hello ! So , i have a stupid problem with my galaxy s4 gt-i9505 . The phone was working perfectly until i installed the leaked 4.3 firmware ,but i reverted to 4.2.2 because of the battery life . Well , after i reinstalled the 4.2.2 the phone started to shutter and lag very bad , even touchwiz lags and games shutter stupidly . Recovery restores did not helped with anything (i did 5 of them) . I went to my operator and i explained them what is the problem , and they sent it into service , but they said that the phone is ok .After it came from the service i got frustrated , i rooted the phone and installed the google play 4.4 edition rom . Now , the phone works marginally better , but still shutters in games and sometimes in the launcher . I am not writing this because i am mad at samsung , but i want to ask you guys if you have any ideea of what is the problem . Thanks a lot !!!
Hello , so i got my new phone galaxy note3 and i updated it to the new android 4.4.2 and it seems it drains the battery like way to fast,
in the older version of 4.3 it didnt happen at all this is so obvious that something its the Android System takes to much battery its always on top can anybody help me to root to the original stock rom of android 4.3 with all working functions? Or is any update coming to the note3 to fix this ? i know that the warranty will go off but i dont need it anyway all i want is battery !

There is no unusual battery drain in 4.4.2 if not factory reseted do it, it will fix your problem, u can't go back to 4.3 now.
If you do a google search you will see there are many many users affected by the battery drain bug. Im yet to find a fix.
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
Hi
I have a Samsung S4 I9500 with 4.4.2 official,some days ago I install Android 5.0.1 official, the rom is I9500XXUHOA7 from Russia with Odin 3.09, the installation was normally I use the option AP.
But i have the next problems:
- The screen of the phone too hot on top only with normal use without playing.
- The battery lasts much less.
Is there any way to return 4.4.2 or solve these problems
Thanks
Odin it back to 4.4.2 thats what I had to do wait for 5.1 to see if it fixes up these pesky bugs.
I believed im the only with top screen hot.

Battery & Gestures
I like the lollipop update except two things battery,something I think Sammy needs to address, second problem is that the Gestures are not fully working i.e scrolling when using stock browser. I've tried both Russian and Indian firmwares both same result. Anyone notice this or anything else?
Oh! dirov if you do downgrade make a backup & bk your imei. Report back how you get on, Good Luck!

İ can say that lollipop is the perfect but has one flaw.Battery life is shorter than kitkat.For example i can get nearly 6 hours screen open time(sot).After lollipop hardly 4 hours sot i can get.Beside that lollipop is smoothest version ever.Everything with animation and fast.If you install a rom with s6 or note 4apps your phone will fly.More stable and good looking apps also.
The answer is posted all over the forum .
Some say its poor but usually they lack experience .
Many of the custom roms are working fine not found battery any different but i don't count battery seconds .
However as you have N900 i would read the N900 posts first as the majority on here are N9005 .
