so I have been googling everywhere for the past few days and cant come up with clear answers so i decided to try a post. I have my phone rooted and wanted to try flashing a rom. I saw 2 roms that interested me that I wanted to try in cyanogenmod and jedi x. thing is, I want to keep my wifi calling and both roms say they remove that feature. Now i read somewhere that there is a way to protect that feature but it didnt go into detail so i was wondering if anyone here knew how to keep the wifi calling feature with one of those 2 custom roms? also, i know that in order to flash a rom I have to data wipe, So i was wondering how do i backup my contacts first before i do this? lastly if i choose to remove the bloatware from my stock rom and not flash a custom rom, does anyone know of a way to change the shortcuts on the lockscreen or of a way to get the music player to work on the lockscreen? thanks in advance for any help.
