Last week I was so desperate with the “Official Firmware Upgrade” in Indonesia area, from Jelly Bean 4.2 to Jelly Bean 4.3
The 4.3. upgrade was doing so bad. My S4 performance was being poor. Here are some result after I’m using 4.3. :
- Long charge battery and fast drain in use.
- The swipe screen is not smooth.
- The WiFi connection in not stable. It can disconnected by self when the device receive less that two bar signal.
Then i decided to search better upgrade. I found KitKat 4.4.2. in Rusian release for S4. I downloaded the file..damn..1.5 GB and being 2 GB after extraction.
Using Odin 3.0.9. i done my S4 upgrade from Jelly Bean 4.3. to KitKat 4.4.2. I’m very satisfied with the result and my S4’s performance raised more than when i’m using Jelly Bean 4.2. from the factory.
The battery is much much longer for standby and talk time. The charging time needs maximum of 2 hours. The WiFi is back to stable connected. The swipe screen is very smooth like before.
