I use my phone in the car a lot so GPS, Bluetooth and 4G Internet have to work
I use wifi instead of 4G at home and even though I don't use NFC at present, I plan to in future
No1 Omega 2.0 (The BEST one) - Everything worked flawlessly (installed G900i modded kernel from install)
NFC did NOT work in any of the other roms but if that doesn't concern you, here is a rundown.
No2 Shohat 5.0 - Everything worked except NFC
No3 Pheonix 1.2 - Everything except NFC and Navigon (Google maps worked but Navigon locked up the phone badly)
No4 Echoe 2.0 - Had troubles keeping the bluetooth connection (navigation kept dropping out all the time)
No5 XtreStoLite 1.0.2 - Most of my apps force closed and wifi connected but then turned off (Big Disappointment)
At No6 is Alliance 1.1 - I couldn't really test this one as the default colour scheme meant I couldn't set it up
The text and check box colours were the same as the background so it was just a blank.
This is just my opinion from tests I have done and others may have differing experiences but hope it helps people wanting to try out
some of the roms.
