Hi, I am a new android user. I recently upgraded by SGH-I747M phone on Rogers to 4.3. Since the upgrade the phone runs really sluggish and cache is always above 1GB even after clearing. I did the update over wifi and was advised by Rogers to re-install the firmware. How do I re-install the 4.3 OS without deleting all my data? I tried to go into Kies but it asks me to initialize which deletes all the data.
Please help. Thanks.
