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.
