Hi Guys,

It's been more than a year since i purchased my Samsung galaxy S3 and almost the same amount of time since i have done any modifications on any android device. I have been facing quite a lot of issues especially when it comes to the speed. At the moment, i have a Samsung Galaxy S3 GT-I9300 with the following specs:

Android version 4.1.2,
Baseband version I9300XXEMA5,
Kernel Version 3.0.31-1287119 se.infra@Sep-78 #1 SMP PREEMPT Fri Jun 28 00:40:06 KST 2013
Build Number JZ054J.I9300XXEMF6

I have the following concerns/questions:

1. Why Slow Speed?
2. If a stock s3 is upgradable to 4.3 then why is my current version 4.1.2 even when though i have tried the software upgrade via wifi and Kies. Can it be upgraded through any other means?
3. How can i root it without bricking it

appreciate an expert opinion on this.

1. don't know, maybe after upgrade and full wipe it is solved (backup data before)
2. maybe in your country an upgrade is not available at the moment. you can also upgrade with odin. download a 4.3 sammy rom and flash it through odin. how to is in the general section - stickies
3. again stickies. alternative: choose a prerooted stock firmware or a custom sammy rom and flash it through a custom recovery (recovery has also to be flashed threough odin e.g. philz)

Slow speed as in memory is usually used upto 80%, hardly any applications are running in the background, too much lagging, applications take a lot of time to open etc.

This also happens even when i have turned my sync off and have limited the applications to at most 2 process at a time.
