nothing wrong don't worry

ota update just download the update only, the size is smaller
use kies update is download the full firmware, size is larger

ota update is use phone to update
go setting > about phone > software update

if you didn't the 2 things then camera is working

supersu apps is in user app which mean I can uninstall
get it ?

anyone try use the EyxnosAbuse apk v1.4 to root your device?

As you said, it is LTE version. We don't have lte yet bro.. So why pay more $$ for something you cant use yet..

but here got one fella using.. SamsungXP..
Very bising with his S3 LTE..
sent from a non-lte S3

or use exynos abuse

*don't use the root method for international version
as I say, if you buy LTE, nobody can answer your answer because nobody own lte s3

Sent From Non-LTE I9300

i think its just silly to get s3 lte when we dont have it here now. 2gb ram but se lte is dual core ,rite? so for extra 1 gb ram but less 2 core of cpu.. not only not worth it ...but its just plain stupid.

so far nobody kena that exploit bugs...yet 

that one not bugs..it only shows that your phone have exynos exploit that can be use. All you need to do is use that ExynosAbuse to close that exploit so no roque app can have your phone root system without notice.

my phone already rooted long ago..and no..my camera work without problem even with the exploit disable.
and yes..you can root your phone via ExynosAbuse apk.

Up to u actually. Disabling it will help ur phone from being exploit by nasty app installed. With the cost of back camera not working. But u can always enable it when u want to use camera

For rooted user, check this post n u can use the camera without needing to enable the fix. No hassle

Get MobileOdinPro instead of the Lite (free one).
It will make easier to flash new firmware without losing your root.

- you download new firmware from Sammobile and put the zip files in your phone.
- unzip that files into .tar.md5 files.
- open MobileOdin and click at Open file..
- search and put your firmware .tar.md5 files
- MobileOdin will auto fill that files into separate section such as cache..param..kernel.. etc..etc
- tick/enable  everything in Everroot section. (Inject Everroot inject SuperSU and inject MobileOdin) This will keep your phone rooted.
- flash firmware and you're done.

Modem..and sometimes language and extra apps that not available here.
