My new Samsung Galaxy Advance S is running with android Gingerbread. I am thinking to upgrade it to Jelly Bean. I am very new to Android devices.
I have following basic questions
- Are there any known advantages and disadvantages in upgrading my device to JellyBean?
- If I upgrade to Jelly Bean do my all apps remain works?
- Upgrading OS, does it void my warranty?
- Is there any official instruction to upgrade my phone to Jelly Bean?
Thanks in advance
