hello Guys,
I would like to know what steps should we take to ensure maximum performance before installing a new official firmware.
I'm about to manually upgrade my galaxy s4 I9505 from jelly bean 4.3 to Kitkat 4.4.2 through Odin and i was just wondering whether or not i should format/erase/factory reset all the data currently the phone before stepping in into the new firmware? Will the new firmware erase the existent one? without the need of format?
I would like to know your expert view on this subject,
many thanks in advance.
