Yes..should be okay for rooting. But flashing different kernel or custom recovery sometimes bring problem. I sofbricked my phone twice and need to go to service centre.

Safest way is either you root and stay on stock rooted ROM or flash custom ROM and use it without tweaking anything else.

Look at that custom ROM thread and follow each and every step.
Then you should be okay. If that custom ROM need to be flash via CWM then use CWM and not TWRP or Philz. Like I said..follow each step carefully to avoid any problem.

Good luck to you

Forget bout S3 flashing...with SELinux and Knox combo..everything changed. Using different custom recovery can get your phone into bootloop.

Root phone then pick which custom ROM you want. If that custom rom state use CWM then only you flash CWM. After flash and install CWM..do Nandroid backup first..then proceed with flashing that custom ROM.

I use two 64GB Sandisk Ultra Class 10 without any problem..so far

Easy for Sandisk

Ultra < Extreme < Extreme Pro

Why..?
That's a standard S4 setting tabs..always been like that even on stock firmware.

Ooo...I see...did you change any dpi..?
Or maybe you need to do full wipe after flashing custom ROM

Ehehe..Ultra Class 10 also okay..
I use the 64GB without any problem. Just remember not to transfer many big files at one go. Transfer big files in smaller portion a few times.

The phone will go into safe mode or auto showndown before it become overheat. Don't worry bout the temperature.

Only repairs at service centre otherwise your whole warranty void.

Bahh..I had enough of S Series..later most features comes out half baked...then buggy somemore.

Just flash the new version. .

Yes..just be carefull when changing type of custom recovery as sometimes your Nandroid won't restored if you use different recovery.

Unless you love go jogging with your S4 strap at your arm, Ant+ bring nothing new to ordinary user.
But...it do still a good things.

It shouldn't be if you already disabled it.

If your battery start swollen..go get a replacement.
BTW..our battery have a 6months mandatory warranty.

If your SELinux still permissive then yes..you can safely root your phone. After you root your phone you won't get any updates anymore.

You need to manually do the update via Odin or MobileOdin if you use LTE version. Flashing via Odin will unroot your phone and if that update bring your status from permissive to enforcing then you need to be very careful not to trip your Knox flag.

I see..same here
BTW...flashing stock firmware won't trigger the Knox warranty flag.
