So Coming from the tmobile Galaxy 4 to the tmobile Galaxy 5 my question is will the s5 be the same as the 4 can we flash Roms from the General Galaxy 5 or only tmobile Roms are compatible ??? I know WIFI Calling won't work since their roms obiously don't have that built in ?? Voice over LTE ??? We will lose this also Correct ??? Will everything else work ? calls/messages/mms/etc etc I'm more than happy with my tmobile Rom at the moment works flawlessly just trying to have this as an information Thread ? for future reference and other people that may be wondering the same thing ????
